The present disclosure relates to: (a) processes for the preparation of (3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (referred to herein as “Compound 1”), (b) intermediates used in the preparation of Compound 1 and processes for preparing the intermediates; (c) solid state forms of Compound 1, (d) pharmaceutical compositions comprising one or more solid state forms of Compound 1, and, optionally, one or more additional therapeutic agents; (e) methods of treating Janus kinase-associated conditions (including rheumatoid arthritis) by administering one or more solid state forms of Compound 1 to a subject in need thereof; (f) kits comprising a first pharmaceutical composition comprising a solid state form of Compound 1, and, optionally, a second pharmaceutical composition comprising one or more additional therapeutic agents; (g) methods for the preparation of solid state forms of Compound 1; and (h) solid state forms of Compound 1 prepared in accordance with such methods.
(3S,4R)-3-ethyl-4-(3H-imidazo[1,2-a]pyrrolo[2,3-e]pyrazin-8-yl)-N-(2,2,2-trifluoroethyl)pyrrolidine-1-carboxamide (“Compound 1”) was first disclosed in International Application WO2011/068881A1, which is herein incorporated by reference in its entirety. The compound has activity as a Janus kinase (“JAK”) inhibitor, particularly as a JAK-1 inhibitor. Clinical trials are ongoing to evaluate the use of the compound to treat rheumatoid arthritis.
The isolation and commercial-scale preparation of a solid state form of Compound 1 and corresponding pharmaceutical formulations having acceptable solid state properties (including chemical stability, thermal stability, solubility, hygroscopicity, and/or particle size), compound manufacturability (including yield, impurity rejection during crystallization, filtration properties, drying properties, and milling properties), and formulation feasibility (including stability with respect to pressure or compression forces during tableting) present a number of challenges that are discussed in greater detail below. Accordingly, there is a current need for one or more solid state forms of Compound 1 that have an acceptable balance of these properties and can be used in the preparation of pharmaceutically acceptable solid dosage forms.
Additionally, currently known processes for the preparation of Compound 1 involve the use of particularly hazardous reagents, such as trimethylsilyldiazomethane or diazomethane, and do not produce a crystalline product. There is thus also a need for a process for preparing Compound 1, and pharmaceutically acceptable salts thereof, that avoids the use of particularly hazardous reagents, and can produce a crystalline product and crystalline intermediates.
Additionally, sustained peak plasma concentrations can theoretically be achieved by means of sustained release matrix systems. However, when such systems are made of hydrophilic polymers, such as HPMC, they seldom provide pH independent drug release of pH-dependent soluble drugs, and they are normally incapable of attaining zero-order release except for practically insoluble drugs. Unexpectedly, is has been discovered that when tartaric acid is used as a pH-modifier in such a system, it allows Compound 1 to be released at a steady rate regardless of the pH of the environment. In an unexpected finding, it was discovered that as a tablet containing the hydrophilic polymer matrix system erodes, Compound 1 reacts with the HPMC, creating a thicker gel layer which slows the release of Compound 1 from the tablet. The resulting gel layer provided an environment suitable for Compound 1 to dissolve.
Axial spondyloarthritis (axSpA) encompasses a spectrum of inflammatory involvement of the axial skeleton. Based on the Assessment of SpondyloArthritis International Society (ASAS) axSpA criteria, the disease can be further divided into 2 categories by radiographic findings: ankylosing spondylitis (AS), and an “early” form of axial SpA, referred to as non-radiographic axial spondyloarthritis (nr-axSpA). Patients with nr-axSpA and AS share common epidemiological, genetic, and clinical disease characteristics, including with regard to disease activity, and similar response to treatment. See, e.g., Poddubnyy and Sieper, Curr Opin Rheumatol. (2014) 26:377-383.
Per international treatment recommendations, nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line therapy in axSpA. See, e.g., van der Heijde D et al., Ann Rheum Dis. (2017) 76:978-991; Ward et al., Arthritis Rheumatol. (2016) 68:282-298. After failure of two NSAIDs given over a maximum of four weeks, biologic disease-modifying anti-rheumatic drugs (bDMARDs) are the next recommended treatment option. In axSpA, conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and long-term corticosteroids are not efficacious and therefore not recommended for treatment of axial symptoms. See, e.g., van der Heijde D et al., Ann Rheum Dis. (2017) 76:978-991. Furthermore, only approximately 45% to 50% of patients show an Assessment of SpondyloArthritis International Society 40 (ASAS40) response and only approximately 15% to 20% achieve a state of remission in biologic-naïve patients, and response rates are even less in axSpA patients who had an inadequate response to bDMARDs. See, e.g., Sieper and Poddubnyy, Lancet (2017) 390:73-84; Sieper et al., Ann Rheum Dis. (2017) 76:571-592; Rudwaleit et al., Arthritis Res Ther. (2010) 12:R117; Deodhar et al., Arthritis Rheumatol. (2019) 71:599-611. To date, other than NSAIDs, there have been no oral targeted therapies approved for the treatment of ankylosing spondylitis (AS) or non-radiographic axSpA.
Psoriatic Arthritis (PsA) is a chronic systemic inflammatory disease classified as a sub-type of spondyloarthritis (SpA) and characterized by the association of arthritis and psoriasis. The course of PsA is usually characterized by flares and remissions. Left untreated, patients with PsA can have persistent inflammation, progressive joint damage, disability, and a reduced life expectancy. Initial treatment of the musculoskeletal symptoms is composed of nonsteroidal anti-inflammatory drugs (NSAIDs) and local corticosteroid injections, while topical therapies are used for the initial treatment of psoriasis. For subjects who experience lack of efficacy or toxicity with these measures, systemic therapy with non-biologic disease modifying anti-rheumatic drugs (non-biologic DMARDs) (e.g., methotrexate [MTX], leflunomide [LEF], sulfasalazine [SSZ]) and ciclosporin A, followed by anti-tumor necrosis factor (TNF) therapy in subjects who do not respond adequately, is recommended. Other biologic therapies (e.g., IL-12/23 or IL-17 inhibitors) are also recommended as alternatives to anti-TNF inhibitors in selected PsA subjects. See, e.g., Gossec et al., Ann Rheum Dis. (2016) 75:499-510; Coates et al., Arthritis Rheumatol. (2016) 68:1060-71. However, despite the beneficial results achieved with currently available biologic agents, approximately 40% of patients do not have at least 20% improvement in American College of Rheumatology (ACR) scores and only 58% to 61% of patients with PsA who receive them are able to achieve clinical remission after 1 year of treatment, with only approximately 43% achieving sustained remission for at least 1 year. See, e.g., Gossec et al., Ann Rheum Dis. (2016) 75:499-510; Alamanos et al., J Rheumatol. (2003) 30:2641-2644; Savolainen et al., J Rheumatol. (2003) 30:2460-8; Sandborn, Dig Dis. (2010) 28:536-42; Saber et al., Arthritis Res Therapy (2010) 12: R94; Perrotta et al., J Rheumatol. (2016) 43:350-5.
Thus, there continues to remain a clear medical need for additional therapeutic options for the treatment of non-radiographic axial spondyloarthritis (nr-axSpA), ankylosing spondylitis (AS), psoriatic arthritis (PsA), and psoriasis (PsO), including PsO as a skin manifestation of PsA.

Domains used for the ASAS responses are as follows:
ASAS20 Response: Improvement of ≥20% and absolute improvement of ≥1 unit (on a scale of 0 to 10; 0=no pain and 10=worst possible pain) from Baseline in ≥3 of the above 4 domains above, with no deterioration (defined as a worsening of ≥20% and a net worsening of ≥1 unit) in the potential remaining domain.
ASAS40 Response: Improvement of ≥40% and absolute improvement of ≥2 units (on a scale of 0 to 10; 0=no pain and 10=worst possible pain) from Baseline in ≥3 of the above 4 domains above, with no deterioration (defined as a net worsening of >0 units) in the potential remaining domain.
ASAS partial remission (PR): an absolute score of <2 units (on a scale of 0 to 10; 0=no pain and 10=worst possible pain) from Baseline for each of the 4 domains above.
ASAS 5/6 Response: Improvement of ≥20% from Baseline in 5 out of the following 6 domains: BASFI, Patient's Assessment of Total Back Pain, PtGA-disease activity, inflammation (mean of Questions 5 and 6 of the BASDAI]), lateral lumbar flexion from BASMI, and hs-CRP.
The ASAS HI is a linear composite measure with a dichotomous response option: “I agree” and “I do not agree” to a listing of 17 Questions. Each statement on the ASAS HI is given a score of “1”=“I agree” or “0”=“I do not agree.” The total sum of the ASAS HI ranges from 0-17, with a lower score indicating a better health status. Questions 7 and 8 are not applicable to all patients. For those patients who ticked the response “not applicable,” the sum score is analyzed based on n=16 or n=15 respectively. A total score can be analyzed if no more than 20% of the data (i.e., 3 Questions) are missing. The total score is calculated as follows for respondents with up to a maximum of three missing responses: Sum.score=x/(17−m)*17, where x is the Question summation score and m is the number of missing Questions and m≤3. Cases with more than three missing responses (m>3) cannot be allocated a total score and the total score will be set as missing. The 17 ASAS Health Index Questions are as follows:
1. Pain sometimes disrupts my normal activities.
2. I find it hard to stand for long.
3. I have problems running
4. I have problems using toilet facilities.
5. I am often exhausted.
6. I am less motivated to do anything that requires physical effort.
7. I have lost interest in sex.
8. I have difficulty operating the pedals in my car.
9. I am finding it hard to make contact with people.
10. I am not able to walk outdoors on flat ground.
11. I find it hard to concentrate.
12. I am restricted in traveling because of my mobility.
13. I often get frustrated.
14. I find it difficult to wash my hair.
15. I have experienced financial changes because of my rheumatic disease.
16. I sleep badly at night.
17. I cannot overcome my difficulties.
Parameters used for the calculation of ASDAS:
Calculation of ASDAS:
ASDAShs-CRP=0.121×total back pain+0.110×PtGA+0.073×peripheral pain/swelling+0.058×duration of morning stiffness+0.579×Ln(hs-CRP+1).
ASDASESR=0.113×patient global+0.293×√ESR+0.086×peripheral pain/swelling+0.069×duration of morning stiffness+0.079×total back pain.
To calculate observed ASDAS scores, the observed component value will be calculated first. Then the components will be included in the calculation per the ASDAS formula. If any observed component is missing in a window, then the observed ASDAS score will be missing.
When the conventional CRP is below the limit of detection or when the high sensitivity CRP is <2 mg/L, the constant value of 2 mg/L should be used to calculate ASDAS-CRP.
ASDAS score is categorized by the following ASDAS Disease Activity States:
ASDAS Response categories are defined as follows:
Each of the 18 statements on the ASQoL (provided below) is given a score of “1” (yes) or “0” (no). Concepts measured include activities of daily life, emotional functioning, pain, fatigue, and sleep problems. A score of “1” is given where the Question is affirmed (with a “yes” answer), indicating adverse QoL. All Question scores are summed to give a total score or index. Scores can range from 0 (good QoL) to 18 (poor QoL), with higher scores equaling worsening functioning. Cases with more than three missing responses (i.e., more than 20%) cannot be allocated a total score. For cases with between one and three missing responses, the total score is calculated as follows: T=18x/18−m where: T is the total score, x is the total score for the Questions affirmed and m is the number of missing Questions.
1. My condition limits the places I can go
2. I sometimes feel like crying
3. I have difficulty dressing
4. I struggle to do jobs around the house
5. It's impossible to sleep
6. I am unable to join in activities with my friends/family
7. I am tired all the time
8. I have to keep stopping what I am doing to rest
9. I have unbearable pain
10. It takes a long time to get going in the morning
11. I am unable to do jobs around the house
12. I get tired easily
13. I often get frustrated
14. The pain is always there
15. I feel I miss out on a lot
16. I find it difficult to wash my hair
17. My condition gets me down
18. I worry about letting people down
The BASDAI consists of a 1 through 10 scale (1 being no problem and 10 being the worst problem) and is used to answer 6 questions pertaining to the 5 symptoms: Fatigue, Spinal pain, Joint pain/swelling, Areas of localized tenderness (also called enthesitis, or inflammation of tendons and ligaments), Morning stiffness duration, and Morning stiffness severity. A lower score indicates less disease activity.
The six BASDAI Questions (Components) are as follows:
Questions 1 through 5 have responses that can range from 0 (none) to 10 (very severe); Question 6 have response range from 0 (0 hr) to 10 (2 or more hrs), with 5 representing 1 hr.
Scoring of the BASDAI: BASDAI will be reported 0 to 10. The score has a maximum value of 10 and is calculated as follows:
BASDAI Score=0.2(Q1+Q2+Q3+Q4+Q5/2+Q6/2)
If one of the 5 Questions (Questions 1-Question 4, inflammation) is missing, then the score is the mean of the 4 non-missing Questions (total of 4 non-missing Questions divided by 4). If more than 1 of the 5 Questions is missing, then the BASDAI score is missing. Question 5 and Question 6 jointly constitute Question 5 (inflammation). If both Questions 5 and 6 are missing, and questions 1 through 4 are non-missing, then only one Question will be considered missing. The BASDAI score can still be calculated as the mean of Questions 1-4. However, if, for example, both Question 6 and Question 1 are missing, then 2 Questions will be considered missing, as the inflammation calculation would be incomplete. The BASDAI score would then be considered missing in this case.
A BASDAI 50 response is a categorical response based on BASDAI that represents an at least 50% improvement from baseline in BASDAI.
The Morning Stiffness Score is the average of BASDAI Questions 5 and 6, and it ranges from 0-10.
A “change from baseline in BASDAI and BASDAI Questions (Components), including change from baseline in mean of Question 5 and 6 of the BASDAI” means (1) a change from baseline from the BASDAI Score, (2) a change from baseline in all of the BASDAI Questions, and (3) a change from baseline of the mean of Questions 5 and 6 (which represent inflammation).
The BASFI consists of the following 10 questions, assessing ability to perform activities such as dressing, bending, reaching, turning, and climbing steps, each with a response ranging from 0 (easy) to 10 (impossible):
1. Putting on your socks or tights without help or aids (e.g., sock-aid).
2. Bending forward from the waist to pick up a pen from the floor without an aid.
3. Reaching up to a high shelf without help or aids (e.g., helping hand).
4. Getting up out of an armless dining room chair without using your hands or any other help.
5. Getting up off the floor without help from lying on your back.
6. Standing unsupported for 10 minutes without discomfort.
7. Climbing 12 to 15 steps without using a handrail or walking aid. One foot on each step.
8. Looking over your shoulder without turning your body.
9. Doing physically demanding activities (e.g., physiotherapy, exercises, gardening, or sports).
10. Doing a full day's activities whether at home or at work.
See, e.g., Sieper et al., Ann Rheum Dis (2009) 68 (Suppl II): ii1-ii44. doi:10.1136/ard.2008.104018.
Scoring of BASFI. The BASFI score will be derived based on the average of Questions 1 through 10. If up to 2 Questions are missing, corresponding scores will be replaced with the mean of the remaining non-missing Questions. If 3 or more Questions are missing, BASFI will be considered missing.
The Linear BASMI (BASMIlin) composite score will be calculated using the BASMI components. The table below presents the components of BASMIlin and assessment ranges for score.
Scores for each assessment range from 0 to 10, and the BASMIlin total score will be the average of the 5 assessment scores. If 1 Question is missing, the BASMIlin will be calculated as the mean of remaining 4 Questions. Hence, the range of the BASMIlin total score should be between 0 and 10. If 2 or more Questions are missing, then the BASMIlin score will be considered missing. See e.g., van der Heijde et al., Arth. Care & Res. (2012) 64:1919-1922 and van der Heijde et al., Ann Rheum Dis (2008) 67:489-93.
For the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index, 16 sites are evaluated as indicated in rows 1-8 in the table below. Tenderness on examination is recorded as either present (coded as 1), absent (coded as 0), or not assessed (NA) for each site. The SPARCC enthesitis index is calculated by taking the sum of the scores from the 16 sites. The SPARCC score ranges from 0 to 16.
The Leeds Enthesitis Index evaluates enthesitis at the 6 entheseal sites indicated in rows 2, 7 and 9 in the table below. Tenderness on examination is recorded as either present (coded as 1), absent (coded as 0), or not assessed (NA) for each of the 6 sites. The LEI is calculated by taking the sum of the scores from the 6 sites. The LEI ranges from 0 to 6.
The Total Enthesitis Count is calculated by taking the sum of the tenderness scores from all 18 sites in the table below.
The proportion of subjects with resolution of enthesitis sites included in the LEI is defined as the proportion of subjects with LEI=0; the proportion with resolution of the SPARCC Enthesitis Index and of the total enthesitis count are similarly defined (score=0).
The Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) will be measured to assess the presence (1) or absence (0) of enthesitis at 13 different sites (first costochondral joint left/right, seventh costochondral joint left/right, posterior superior iliac spine left/right, anterior superior iliac spine left/right, iliac crest left/right, fifth lumbar spinous process, and proximal insertion of Achilles tendon left/right), noting the subjects' responses, yielding a total score ranging 0-13. If one or more locations are missing, the score will be calculated using available data. If all locations are missing, then MASES is set to be missing.
The EQ-5D-5L questionnaire is one of the most commonly used questionnaires to measure health-related quality of life. It consists of a questionnaire and a visual analogue scale (VAS). The self-assessment questionnaire measures 5 dimensions of health status (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). The AS subject is asked to grade their own current level of function in each dimension into 1 of 3 degrees of disability (severe, moderate, or none). The PsA subject is asked to grade their own current level of function in each dimension into 5 levels per dimension (no problems, slight problems, moderate problems, severe problems, and extreme problems corresponding to Level 1 to Level 5 respectively) and includes the EQ Visual Analogue Scale (EQ VAS). The 5 dimensions of health status are converted into a single index value. Using the VAS, subjects record perceptions of current perceived health status with a grade ranging from 0 (the worst possible health status) to 100 (the best possible health status).
High-Sensitivity C Reactive Protein (hs-CRP)
C-reactive protein (CRP), which is measured in blood plasma, is an acute phase protein that appears in blood circulation in response to inflammation, and serves as a biomarker for systemic inflammation. However, routine methods of CRP detection (turbidimetric, nephelometric) demonstrated poor sensitivity in detecting concentrations of CRP below 6-10 mg/litre. See, e.g., Poddubnyy et al., Ann. Rheum. Dis. (2010) 69:1338-1341.
The high-sensitivity C-reactive protein (hs-CRP) assay is a more precise measurement than routine CRP. Several different tests may be used to measure the hs-CRP normal range versus abnormal value for the subject to be treated; thus the upper limit of normal (ULN) will be determined by the laboratory for the hs-CRP test used and may differ from laboratory to laboratory.
Swollen Joint Count Assessment (SJC or SJC66): An assessment of 66 joints will be done by physical examination. The joints to be examined for swelling are the same as those examined for tenderness, except the hip joints are excluded. Joint swelling will be classified as present (“1”), absent (“0”), replaced (“9”), or no assessment (“NA”). Joints injected with corticosteroid will be considered non-evaluable for 90 days from the time of the injection. The range for SJC66 will be 0 to 66.
Tender Joint Count Assessment (TJC or TJC68): An assessment of 68 joints will be done for tenderness by pressure manipulation on physical examination. Joint pain/tenderness will be classified as: present (“1”), absent (“0”), replaced (“9”), or no assessment (“NA”). Joints injected with corticosteroid will be considered non-evaluable for 90 days from the time of the injection. The range for TJC68 will be 0 to 68.
Anatomical joints are evaluated for swelling and tenderness at every study visit. The 34 anatomical joints in the below table are assessed in this study for both the left and right side of the body.
aHip joints are not assessed for swelling.
Modified Stoke Ankylosing Spondylitis Spine Score (mSASSS)
The mSASSS is a scoring method that measure radiographic progression in the spine of patients with ankylosing spondylitis. The mSASSS has a range of 0 to 72, which is derived from scoring the anterior site of the lumbar spine from the lower border of T12 to the upper border of S1 and the anterior site of the cervical spine from the lower border of C2 to the upper border of T1 as either 0 (normal), 1 (erosion, sclerosis, or squaring), 2 (syndesmophyte), 3 (bridging syndesmophyte), or NA vertebral body not evaluable. X-ray of spinal films will be analyzed for radiographic progression (from Baseline to the follow-up timepoint).
SPARCC scores for spine and sacroiliac (SI) joints are calculated by adding up the dichotomous outcomes from evaluations of the presence, depth and intensity of bone marrow edema lesions of the spine and SI joints, respectively.
In the MRI SPARCC score of Spine, the entire spine is evaluated for active inflammation (bone marrow edema) using the Short-TI Inversion Recovery (STIR) image sequence. 23 discovertebral units (DVUs) are assessed, and the six most severely affected DVUs are selected and used to calculate the MRI Spine SPARCC score. For each of the six DVUs, 3 consecutive sagittal slices are assessed in four quadrants in order to evaluate the extent of inflammation in all three dimensions:
The maximum possible score for any individual slice is 6, with a maximum score for all 6 discovertebral units being 108.
The MRI SPARCC score of SI joints is conducted on 6 consecutive slices of the STIR image sequence. All lesions within the iliac bone and within the sacrum up to the sacral foramina are to be scored. The SI joint is divided into 4 quadrants: upper iliac, lower iliac, upper sacral and lower sacral. Each consecutive slice is scored separately for the right and left joint in all four quadrants as follows:
The maximum possible score for any individual slice is 12, with a maximum score for all 6 slices being 72.
The 36-Item Short Form, Version 2 (SF-36v2) (Quality Metric) health survey consists of 36 general health questions. It has 2 components: physical and mental. For each component, a transformed summary score is calculated using 8 sub domains: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, and mental health. The range is from 0 to 100, with higher scores indicating better outcomes. The coding and scoring for the SF-36 will use the software provided by the vendor.
A “subject” means a human. The terms “patient” and “subject” are used interchangeably herein.
An “adult subject” means a subject 18 years or older.
A “juvenile” or “pediatric” subject means a subject 1 to <18 years old. Juvenile subjects to be treated are subjects diagnosed with juvenile AS (JAS), juvenile PsA (JPsA), and/or juvenile PsO (JPsO) and in need of treatment as determined by a physician (“active juvenile AS” and “active juvenile PsA”, “active juvenile PsO”, respectively). Juvenile AS may be classified per International League of Associations for Rheumatology (ILAR) (defining 7 discrete categories of arthritis starting before the age of 18 years: systemic arthritis, oligoarthritis, polyarthritis (rheumatoid factor [RF]-negative), polyarthritis (RF-positive), PsA, enthesitis-related JIA (or juvenile enthesitis-related arthritis [ERA]), and undifferentiated arthritis). See, e.g., Petty et al., J Rheumatol. (2004) 31:390-2. Juvenile PsA may be classified per pediatric International League of Associations for Rheumatology (ILAR) and/or adult criteria [Classification criteria for Psoriatic Arthritis (CASPAR)]. See e.g., Aviel et al., Pediatric Rheumatology (2013) 11:11; Zisman et al., J. Rheum. (2017) 44:342-351.
The “2009 ASAS classification criteria” for the classification of a subject with axial spondyloarthritis (axial SpA, or axSpA) is described in Rudwaleit et al., Ann. Rheum. Dis. (2009) 68:777-783. The criteria require chronic back pain (≥3 months) in the subject and age at onset <45 years, with the subject also having the following conditions (1) the presence of sacroiliitis by radiography or by magnetic resonance imaging (MRI) plus at least one SpA feature (“imaging arm”) or (2) the presence of human leukocyte antigen (HLA) B27 plus at least two SpA features (“clinical arm”). Sacroiliitis on imaging refers to active (acute) inflammation on MRI highly suggestive of sacroiliitis associated with SpA, or definite radiographic sacroiliitis. SpA features are selected from the group consisting of inflammatory back pain, arthritis, enthesitis (heel), uveitis, dactylitis, psoriasis, Crohn's disease or ulcerative colitis, good response to NSAISs (24-48 hours after a full dose of an NSAID the back pain is not present any more or is much better), family history for SpA, positive HLA-B27, and elevated C-reactive protein (above the upper normal limit in the presence of back pain, and after exclusion of other reasons for elevation). See also Deodhar et al., Arth. & Rheum. (2014) 66:2649-2656.
The “1984 modified New York criteria” for the classification of a subject with ankylosing spondylitis (AS), is described in van der Linden et al., Arthritis and Rheumatism (1984) 27:361-368, and has two components: diagnosis and grading; the diagnosis component further has two criteria: clinical and radiologic. The clinical criteria require: (i) low back pain and stiffness for more than 3 months which improves with exercise, but is not relieved by rest; (ii) limitation of motion of the lumbar spine in both the sagittal and frontal planes, and (iii) limitation of chest expansion relative to normal values corrected for age and sex. The radiologic criterion requires sacroiliitis grade ≥2 bilaterally or sacroiliitis grade 3-4 unilaterally. The grading component requires: (i) definite ankylosing spondylitis if the radiologic criterion is associated with at least 1 clinical criterion; and (ii) probable ankylosing spondylitis if 3 clinical criteria are present, and the radiologic criterion is present without any signs or symptoms satisfying the clinical criteria. See also Deodhar et al., Arth. & Rheum. (2014) 66:2649-2656.

The pre-specified significance level, alpha, is the probability of rejecting the null hypothesis given that it is true. Alpha is also called type I error or false positive rate. It is usually set at or below 0.05. The observed p value is the probability, under the null hypothesis, of observing an effect of the same magnitude or more extreme. When observed p value<alpha, the null hypothesis is rejected, and statistical significance is claimed. In a multiplicity-controlled analysis, when the adjusted p value<alpha, the result is statistically significant. In the fixed sequence of a multiplicity-controlled analysis, statistical significance can be claimed for a lower ranked endpoint only if the previous endpoint in the sequence meets the requirements of statistical significance.

The solid state form may also be combined with an immune modulator for CD4+CD25+ Treg cells. Treg cells are essential for maintaining normal immune homeostasis. In patients with autoimmune diseases, reduced numbers or functional impairment of Treg cells has been observed, leading to loss of this finely-tuned mechanism. A humanized agonistic monoclonal antibody, BT-061, binds to a unique epitope of human CD4, and induces Treg-specific signaling events that lead to their functional activation. Pre-clinical data using isolated Treg cells and rheumatoid arthritis synovial fluid indicate that BT-061 leads to suppression of CD4+ and CD8+T effector cell proliferation, reduction of the expression of pro-inflammatory cytokines, and increase in the production of the anti-inflammatory cytokine TGFβ. Thus similar immune modulators for CD4+CD25+ Treg cells can also be co-administered with a compound of the invention for treating any of the inflammatory disease/disorder, or an autoimmune disease/disorder described herein, including but not limited to rheumatoid arthritis, Crohn's disease, ankylosing spondylitis, psoriatic arthritis, psoriasis, ulcerative colitis, systemic lupus erythematosus, lupus nephritis, diabetic nephropathy, dry eye syndrome, Sjogren's syndrome, alopecia areata, vitiligo, or atopic dermatitis. In certain embodiments, the combination treats rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis, including moderately to severely active rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis. In certain embodiments, the rheumatoid arthritis, Crohn's disease, psoriasis, or psoriatic arthritis patient being treated has inadequately responded to or has discontinued therapy due to loss of response to or intolerance to a first line therapy (such as a DMARD, including methotrexate) or an anti-TNFα therapy.
In certain embodiments, the immune modulator has one or more (or all) of the following properties: (1) activates a subset of CD4+ T cells comprising CD4+CD25+ regulatory T cells (Treg), or CD4+CD25+ Treg cells; (2) binds only to a special epitope of the human CD4 antigen (such as the IgG-like C2 type 1 domain of CD4), which said epitope of human CD4 may be bound by a mouse IgG1 anti-CD4 monoclonal antibody B-F5 or a humanized version thereof, such as the BT-061 hB-F5 antibody tregalizumab as described in U.S. Pat. No. 7,452,981 (incorporated herein by reference, including all sequences of the VH and VL chains disclosed therein); (3) provides an activation signal to naturally occurring Treg cells but does not activate conventional T cells (e.g., CD4+ T cells that are not activated in (1), CD8+ cytotoxic T cells, etc.); and (4) is not a depleting anti-CD4 antibody that depletes CD4+ T cells, and/or does not appreciably trigger ADCC or CDC.

Ankylosing Spondylitis (AS) is a chronic, inflammatory rheumatic disease primarily affecting the axial skeleton, characterized by chronic back pain (including nocturnal back pain), morning stiffness, enthesitis, peripheral arthritis, and extra-articular manifestations. The “early” form of this disease (non-radiographic axial spondyloarthritis (nr-axSpA)) shares many of AS disease characteristics.
Due to the longstanding debilitating nature of AS, irreversible structural damage often occurs, negatively impacting patients' lives. No cure for AS exists, thus the primary goal of treatment is to maximize patients' quality of life through controlling the signs and symptoms of disease, preventing structural damage, and maintaining physical function, ideally by achieving sustained clinical remission or, at minimum, low disease activity. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the first-line treatment for AS, followed by biologic disease-modifying antirheumatic drugs (bDMARDs), such as tumor necrosis factor (TNF) inhibitors or interleukin-17 (IL-17) inhibitors, in patients who do not sufficiently respond to NSAIDs. TNF inhibitors and IL-17 inhibitors are efficacious in some patients with AS, but there are still patients for whom neither of these approved therapies address individual treatment goals. AS is a difficult disease to treat, as shown based on low efficacy achieved with IL-6 inhibitors tocilizumab and sarilumab, as well as IL-12/23 inhibitor ustekinumab and T cell blockade inhibitor abatacept. See, e.g., Sieper et al., Ann. Rheum. Dis. 2014 73:95-100, Sieper et al., Ann. Rheum. Dis. 2015 74:1051-1057; Deodhar et al., Arthritis and Rheumatology 2019 71:258-270, and Song et al., Ann. Rheum. Dis. 2011 70:1108-1110.
The JAK family is composed of 4 members: JAK1, 2, 3, and tyrosine kinase 2 (Tyk2). These cytoplasmic tyrosine kinases act in tandem to activate the Signal Transducer and Activator of Transcription (STAT) that transduce cytokine-mediated signals and are associated with multiple membrane cytokine receptors such as common gamma-chain (CGC) receptors and the glycoprotein 130 trans-membrane proteins. JAK3 and JAK1 are components of the CGC cytokine receptor complexes that are responsible for the signaling of the inflammatory cytokines IL-2, -4, -7, -9, -15 and −21; whereas IL-12 and IL-23 signal through JAK2 and Tyk2. See Ghoreschi, et al., Immunol Rev. (2009), 228:273-87. Propagation of these signals is important in the amplification of inflammatory responses in axial spondyloarthritis (axSpA). Upadacitinib, a JAK inhibitor engineered for increased selectivity for JAK1 over JAK2, JAK3, and tyrosine kinase 2, has been investigated for the treatment of bDMARD-naïve patients with AS who had an inadequate response to non-steroidal anti-inflammatory drugs (NSAIDs) in the randomized, placebo-controlled phase 2/3 SELECT-AXIS 1 study. See Example 31, herein. A second study (SELECT-AXIS-2) expanded the scope of enrollment to non-radiographic axial spondyloarthritis (nr-axSpA) patients and AS bDMARD-IR patients. See Examples 32 and 33 herein.
The SELECT-AXIS 1 met its primary endpoint of significantly greater achievement of Assessment of SpondyloArthritis International Society (ASAS40) response at Week 14, as well as several disease activity measures (ASDAS, BASDAI, ASAS, and their components), inflammation (based on MRI of spine and sacroiliac joints as well as hsCRP), physical function (BASFI), quality of life (ASQoL, ASAS HI), and other aspects of disease (BASMI, MASES), reflecting significant improvement in outcomes for upadacitinib versus placebo. Furthermore, a review of the placebo corrected data for upadacitinib at Week 14, biologics Ixekizumab and Adalimumab at Week 16, and JAK small molecule inhibitors Tofacitinib and Filgotinib at Week 12 for key primary and secondary endpoints, while not a head to head comparison, suggests that upadacitinib 15 mg QD shows decided promise for the more difficult to achieve endpoints ASAS PR, ASDAS ID, and ASDAS LDA versus the other two JAK small molecule inhibitors, with a remarkable efficacy only comparable to that demonstrated with the biologics. See U.S. Pat. App. No. 2021/0228575 (Example 2), and van der Heijde et al. Lancet (2018) 392: 2441-2451, van der Heijde D, et al. Ann. Rheum. Dis. (2017) 1-8; van der Heijde et al. Lancet (2018) 2378-2387. Furthermore, this efficacy, once achieved at Week 14, was sustained or improved over time, with long term efficacy in these difficult to achieve endpoints (including ASDAS major improvement (MI) and ASDAS clinically important improvement (CII)), sustained or improved up to and including Week 64. In patients who switched from placebo to upadacitinib at Week 14, a similar speed of onset and magnitude of efficacy response was observed up to and including Week 64 compared with those who received continuous upadacitinib starting at Week 0. Based on the results of phase 2/3 study SELECT-AXIS 1 and the consistent safety data from other upadacitinib clinical trials, the benefit-risk profile of upadacitinib in AS (particularly compared to the risk profile of other small molecule JAK inhibitors), and viewed in the context of the benefit-risk of TNF inhibitors and IL-17 inhibitors, presents a promising oral targeted treatment option for patients with AS, especially for those AS (as well as nr-axSpA patients) who have active disease and inadequate response to NSAIDs.

The Freebase Hydrate Form C and Amorphous Freebase solid state forms of Compound 1 were formulated into 24 mg extended release tablets according to the formulations set forth in Table 4.
The formulations were prepared by combining and blending the active, microcrystalline cellulose, hydroxypropyl methyl cellulose (HPMC), and colloidal silicone dioxide. The blend was milled using a Mobil Mill fitted with a 610-micron screen. The magnesium stearate was screened through mesh #30 and was added to the bin and blended.
The lubricated granulation was compressed into 480 mg weight tablets using a rotary tablet press. The tablets may optionally be coated with any suitable film coating.
The effect of solid state form on the dissolution profile of the tablets was evaluated. In particular, the dissolution profile of the Example 3 (containing Freebase Hydrate Form C as active) and Example 4 (containing Amorphous Freebase as active) tablets was evaluated at pH 6.8 (representative of the pH in the lower intestine). The dissolution test was carried out using the following dissolution parameters and conditions:
The medium used for the study was a 0.05 M sodium phosphate buffer solution, pH 6.8±0.05. The medium was prepared using an acid stage medium (0.1 N hydrochloric acid solution) and a buffer stage concentrate (0.05 M sodium phosphate buffer concentrate solution, prepared by dissolving about 41.4 g of sodium phosphate, monobasic, monohydrate and about 14.4 g of sodium hydroxide pellets in about 4 L of water, dilute to 6 L with water and mixing well). The medium was prepared by mixing 500 mL of the acid stage medium and 400 mL of buffer stage concentrate in an appropriate size container or directly in the dissolution vessel and adjusting the pH with 1 N phosphoric acid or 1 N sodium hydroxide, if the pH was not within 6.8±0.05.
For the dissolution test, one tablet each was added to a dissolution vessel containing 900 mL of the 0.05 M sodium phosphate buffer solution maintained at 37° C. The paddles of the dissolution apparatus were operated at 75 RPM, with 1.5 mL samples from the dissolution vessel automatically obtained at the designated time periods. The sample filtrate was the sample preparation.
For the analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % of the labelled amount of active released (% LA Released) was calculated. The formulation containing Freebase Hydrate Form C (Example 3) as the active showed a slower rate of dissolution than the formulation containing Amorphous Freebase (Example 4) as the active at pH 6.8.
The dissolution profile of formulations comprising Freebase Hydrate Form C as an active was further evaluated at pH 6.8 and in a dual pH system. In particular, the dissolution profile of the Example 1 (ER1), Example 2 (ER2), and Example 3 (ER3) tablets at pH 6.8 was carried out as described above. The dissolution profile of the Examples 1-3 tablets was also carried out in a dual pH system using the following dissolution parameters and conditions:
The acid stage medium is a 0.1 N hydrochloric acid solution. A buffer stage medium for the study was prepared using a buffer stage concentrate (0.05 M sodium phosphate buffer concentrate solution, prepared by dissolving about 41.4 g of sodium phosphate, monobasic, monohydrate and about 14.4 g of sodium hydroxide pellets in about 4 L of water, dilute to 6 L with water and mixing well). The buffer stage medium of a 0.05 M sodium phosphate buffer solution, pH 6.8±0.05, was prepared by mixing 500 mL of the acid stage medium and 400 mL of buffer stage medium concentrate in an appropriate size container or directly in the dissolution vessel and adjusting the pH of the buffer stage medium concentrate with 1 N phosphoric acid or 1 N sodium hydroxide, if the pH was not within 6.8±0.05.
For the dissolution test, one tablet each was added to a dissolution vessel containing 500 mL of a 0.1 N hydrochloric acid solution maintained at 37° C. The paddles of the dissolution apparatus were operated at 75 RPM for 1 hour, and then a 1.5 mL sample from the dissolution vessel was automatically obtained. After the acid stage sample was obtained, 400 mL of buffer stage medium concentrate was added, maintained at 37° C. The dissolution test was continued, with the paddles remaining at a speed of 75 RPM. The sample filtrate was the sample preparation.
For the analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % relative standard deviation (RSD) of peak areas was calculated for each set of six standard injections.
After the initial release at the low pH (representative of the pH in the stomach), release of the drug is slowed at the higher pH (representative of the pH in the lower intestine). Therefore, in order to achieve the desired bioavailability, a formulation which allowed pH independent release was required.
The Freebase Hydrate Form C solid state form of Compound 1 was formulated into 15 mg, 24 mg, or 30 mg extended release tablets according to the formulations set forth in Table 5 using direct compression.
aProvides 15 mg of Compound 1 freebase equivalent.
bProvides 30 mg of Compound 1 freebase equivalent.
cProvides 24 mg of Compound 1 freebase equivalent.
The formulations were prepared by first milling the tartaric acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The Freebase Hydrate Form C, microcrystalline cellulose, mannitol (when present), milled tartaric acid, release control polymer, and colloidal silicone dioxide (when present) were combined and blended. The blend was milled using a Mobil Mill fitted with a 610- or 1397-micron screen. The magnesium stearate was screened through mesh #30 and was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press.
The Example 5 and 8 tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.40 mg of coating had been applied to the tablets.
The dissolution profile of the Example 9 (ER4, 24 mg active), Example 10 (ER4, no mannitol, 24 mg active), Example 11 (ER5, 24 mg active), and Example 12 (ER6, 24 mg active) tablets was evaluated at pH 1.2, at pH 6.8, and in a dual pH system. The pH 6.8 study was performed as described above for Examples 3 and 4. For the dual pH study, an acid stage medium of 0.05 M sodium phosphate solution, pH 3.5±0.05, was prepared by dissolving about 41.4 g of sodium phosphate, monobasic, monohydrate in about 4 L of water, measuring the pH and adding phosphoric acid, 85%, dropwise as needed to adjust to the target pH. The mixture was diluted to 6 L with water and mixed. A buffer stage medium for the study was prepared using a buffer stage concentrate (0.05 M sodium phosphate buffer concentrate solution, prepared by dissolving about 41.4 g of sodium phosphate, monobasic, monohydrate and about 14.4 g of sodium hydroxide pellets in about 4 L of water, dilute to 6 L with water and mixing well). The buffer stage medium of a 0.05 M sodium phosphate buffer solution, pH 6.8±0.05, was prepared by mixing 500 mL of the acid stage medium and 400 mL of buffer stage medium concentrate in an appropriate size container or directly in the dissolution vessel and adjusting the pH of the buffer stage medium concentrate with 1 N phosphoric acid or 1 N sodium hydroxide, if the pH was not within 6.8±0.05.
The dissolution test was carried out using the following dissolution parameters and conditions:
For the dissolution test, one tablet each was added to a dissolution vessel containing 500 mL of the acid stage medium, maintained at 37° C. The paddles of the dissolution apparatus were operated at 75 RPM for 1 hour, and then a 1.5 mL sample from the dissolution vessel was automatically obtained. After the acid stage sample was obtained, 400 mL of buffer stage medium concentrate was added, and then the mixture was maintained at 37° C. The dissolution test was continued, with the paddles remaining at a speed of 75 RPM. The sample filtrate was the sample preparation.
For the pH 1.2 study, the dissolution test was carried out using the following dissolution parameters and conditions:
For this study, an acidic medium of 0.05 M sodium phosphate solution, pH 3.5±0.05, was prepared by dissolving about 41.4 g of sodium phosphate, monobasic, monohydrate in about 4 L of water, measuring the pH and adding phosphoric acid, 85%, dropwise as needed to adjust to the target pH of 1.2. The mixture was diluted to 6 L with water and mixed.
For the dissolution test, one tablet each was added to a dissolution vessel containing 500 mL of the acidic medium, maintained at 37° C. The paddles of the dissolution apparatus were operated at 75 RPM, with 1.5 mL samples from the dissolution vessel automatically obtained at the designated time periods. The sample filtrate was the sample preparation.
For the analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % relative standard deviation (RSD) of peak areas was calculated for each set of six standard injections. The results shown that pH independence is achieved in the once daily formulations.
The dissolution profile of the Example 5 (ER7), Example 8 (ER8), and Example 9 (ER4) tablets were evaluated in a dual pH system, as described above. The formulations provide an extended release profile of 80-100% over a period of about 8-10 hours.
The formulations of Examples 5 and 8-12 all exhibited pH independent release of the active ingredient. In contrast, after the initial release at the low pH, release of the active is slowed at the higher pH for the formulations of Examples 1-3. Without wishing to be bound to any particular theory, it is believed that the inclusion of tartaric acid as a pH modifier in the Example 5 and 8-12 formulations contributed to the pH independent release observed for these tablets.
The Freebase Hydrate Form C solid state form of Compound 1 was formulated into a 7.5 mg extended release tablet according to the formulation set forth in Table 6.
aProvides 7.5 mg of Compound 1 freebase equivalent.
The formulation was prepared by first milling the tartaric acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The Freebase Hydrate Form C, microcrystalline cellulose, mannitol, milled tartaric acid, release control polymer, and colloidal silicone dioxide were combined and blended. The blend was milled using a Mobil Mill fitted with a 610-micron screen. The magnesium stearate was screened through mesh #30 and was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press.
The tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.4 mg of coating had been applied to the tablets.
The Freebase Hydrate Form C solid state form of Compound 1 was formulated into 15 mg or 30 mg extended release tablets according to the formulations set forth in Table 7. The tablets were prepared using a wet granulation process, and were compressed into tablets having a core weight of about 480 mg.

bProvides 15 mg of Compound 1 freebase equivalent.
cFilm coat weight is approximate.
The formulation was prepared by first milling the tartaric acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The intragranular portion of the hydroxypropylmethyl cellulose release control polymer, the Freebase Hydrate Form C, and intragranular portion of the microcrystalline cellulose filler were added to a granulator, and mixed. Water was sprayed to granulate. The granulated material was then dried and milled using a comill fitted with a 610-micron screen. The milled granulation was then added to the extragranular tablet components other than magnesium stearate, and sieved using a comill fitted with a 1397-micron screen, followed by blending. The magnesium stearate was then added to the bin and blended. The lubricated granulation was compressed into about 480 mg weight tablets using a rotary tablet press.
The tablets were coated using a film coater, which sprayed a solution containing the Opadry® II Yellow film coat and purified water until 14.4 mg of coating had been applied to the tablets.
In this example, the effect of various organic acid pH modifiers (e.g., tartaric acid, citric acid, succinic acid, and fumaric acid) on the release rate of Freebase Hydrate Form C from 24 mg once-daily extended release (ER) tablets was evaluated. Freebase Hydrate Form C was formulated into 24 mg extended release tablets according to the formulations set forth in Table 8.
The formulations were prepared by first milling the organic acid through a Fitz mill Model M5A, fitted with a 1512-0027 screen. The active, microcrystalline cellulose, milled organic acid, and release control polymer, were combined and blended. The blend was milled using a Mobil Mill fitted with a 610-micron screen. The magnesium stearate was screened through mesh #30 and was added to the bin and blended. The lubricated granulation was compressed into 480 mg weight tablets using a rotary tablet press.
The effect of the organic acids on the dissolution profile of the tablets was evaluated at pH 1.2 and pH 6.8. The dissolution tests were carried out using the dissolution parameters and conditions as described above in Examples 3 and 4 and 9-12. For analysis of the sample, conventional liquid chromatography methods were utilized, wherein the % of the labelled amount of active released (% LA Released) was calculated. The results show that organic acids improved dissolution rate at high pH, with tartaric acid showing the best improvement. The formulations comprising the control release polymer Carbopol® with tartaric acid provided near linear release at pH 6.8.
To measure the pH of the environment created when Compound 1 reacts with HPMC, the following experiment was performed.
The Freebase Hydrate Form C solid state form of Compound 1 was formulated into 30 mg extended release tablets according to the formulations set forth in Table 9A. The tablets were prepared using a wet granulation process, as described in Examples 14-19.
Dissolution media of 0.01 N HCl (pH 2) and 113 mM sodium phosphate buffer (pH 6.8) was prepared at 37° C. One tablet was added to 500 mL of 0.01 N HCl media and stirred at 75 rpm at 37° C. for one hour in a Vankel VK 7010 dissolution bath. Then 400 mL of sodium phosphate buffer was added. The solution was stirred an additional three hours. The tablet was removed, rinsed with water and dried using laboratory tissues. The gel that formed on the tablet was separated from the dry core for pH measurement. This procedure was repeated three times for each formulation. The pH of the gel formed on the tablets is set forth in Table 9B.
The pharmacokinetic profile of the 15 mg once-daily extended release (ER) tablets prepared in Example 5 was evaluated, and compared to that of a 12 mg immediate-release (IR) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects (n=11) were administered a single dose of the 12 mg IR capsule (Regimen A) and the 15 mg ER (once-daily) tablet from Example 5 (Regimen B) under fasting conditions in a randomized, two-period, cross-over study design. Subjects were administered Regimen A in the first study period and Regimen B in the second study period, or administered Regimen B in the first study period and Regimen A in the second study period. Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen. The results are summarized in Table 10A.
aMedian (minimum, maximum)
bHarmonic mean (pseudo-% CV)
cData in parentheses is coefficient of variance of the PK parameter (% CV), unless otherwise indicated.
As can be seen from this data, the 15 mg ER tablet provided a lower Cmax and comparable AUC to the 12 mg IR capsule under fasting conditions.
The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen B) relative to the IR capsule formulation (Regimen A) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 10B below.
For Regimen B versus Regimen A, the point estimates for the ratios of AUCt and AUCinf were near unity, and the 90% confidence intervals were within the 0.86-1.09 range.
The pharmacokinetic profile of the 30 mg once daily extended release (ER) tablets prepared in Example 8 was evaluated, and compared to that of a 24 mg dose of an immediate release (IR) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects (n=12) were administered a single 24 mg dose (two 12 mg IR capsules) (Regimen C) and the 30 mg ER (once daily) tablet from Example 8 (Regimen D) under fasting conditions in a randomized, two-period, cross-over study design. Half the subjects were administered Regimen C in the first study period and Regimen D in the second study period, while the other half were administered Regimen D in the first study period and Regimen C in the second study period. Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen. The results are summarized in Table 11A.

As can be seen from this data, the 30 mg ER tablet provided a lower Cmax and comparable AUC to the 24 mg dose IR capsule (2×12 mg) under fasting conditions.
The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen D) relative to the IR capsule formulations (Regimen C) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 11B below.
For Regimen D versus Regimen C, the point estimates for the ratios of AUCt and AUCinf were near unity, and the 90% confidence intervals were within the 0.82-1.03 range.
The pharmacokinetic profile of the 30 mg extended release tablets prepared in Example 8 after a high-fat meal was evaluated, and compared to the pharmacokinetic profile of the 30 mg extended release tablets under fasting conditions (see Example 23).
Following completion of the Example 23 study, the healthy human subjects (n=12) were administered single doses of the 30 mg ER (once daily) tablet from Example 8 after a high-fat meal (Regimen E). Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter, and compared to the pharmacokinetic parameters for the 30 mg tablets administered under fasting conditions (see Example 23, Regimen D). The results are summarized in Table 12A.

The relative bioavailability for a single dose of the once-daily (ER) 30 mg tablet formulation after a high-fat meal (Regimen E) relative to the bioavailability of the ER 30 mg tablet under fasting conditions (Regimen D) was also determined based on analysis of the natural logarithms of Cmax and AUC. The results are summarized in Table 12B below.
As can be seen from Tables 13A and 13B, there is no clinically meaningful food effect for the 30 mg ER tablets. Administration following a high-fat meal increased the Compound 1 mean AUC and Cmax by 17% and 20%, respectively.
The steady state pharmacokinetic profile of the 15 mg once daily extended release (ER) tablets (prepared in Example 5) and the 30 mg once daily ER tablets (prepared in Example 8) was evaluated.
Healthy human subjects (n=24) were assigned to one of two regimens. Subjects in Regimen F (n=12) were administered the 15 mg ER tablet from Example 5 once daily for seven days under non-fasting conditions. Subjects in Regimen G (n=12) were administered the 30 mg ER tablet from Example 8 once daily for seven days under non-fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen. The results are summarized in Table 13A.

As can be seen from this data, the observed steady state Cmax and AUC24 following 15 mg QD and 30 mg QD administration are generally consistent with the single dose and food-effect results obtained in previous studies. The bioavailability of the 15 mg and 30 mg ER tablets is 70% to 80% relative to the same dose of IR capsules.
The steady state pharmacokinetic profile of the 15 mg once daily extended release (ER) tablets (prepared in Example 5) under fasting conditions was evaluated, and compared to that of a 6 mg immediate release (IR) twice daily (BID) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen K (n=12 at onset; n=11 on Day 7) were administered the 6 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen L (n=12) were administered the 15 mg ER tablet from Example 5 once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen. The results are summarized in Table 14A.

The relative bioavailability for the once-daily (ER) tablet formulation (Regimen L) relative to the twice daily (IR) capsule formulation (Regimen K) at steady state was also determined based on analysis of the natural logarithms of Cmax, AUC24, Cmin, and C24. The results are summarized in Table 14B below.
The ratio of steady-state AUC for the 15 mg QD tablets relative to the 6 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The ratio of the steady-state Cmin was approximately 1 for the 15 mg QD tablet relative to the 6 mg BID capsules.
The pre-morning dose trough concentration (Ctrough) for the 6 mg BID capsules and 15 mg QD tablets was determined prior to the morning dose on Days 2-8. At steady state under fasting conditions, the 15 mg QD tablets provided equivalent AUC24 and comparable Cmax and Cmin relative to the 6 mg BID capsules. The steady state Cmax was 10% lower for the 15 mg QD tablet compared to the 6 mg BID capsule.
The steady state pharmacokinetic profile of the 30 mg once daily extended release (ER) tablets (prepared in Example 8) under fasting conditions was evaluated, and compared to that of a 12 mg immediate release (IR) twice daily (BID) capsule comprising Tartrate Hydrate as the active.
Healthy human subjects were assigned to one of two regimens under fasting conditions in a randomized, two-period, cross-over study design. Subjects in Regimen M (n=11) were administered the 12 mg IR capsule twice daily for seven days under fasting conditions. Subjects in Regimen N (n=12 at onset; n=11 at Day 7) were administered the 30 mg ER tablet from Example 8 once daily for seven days under fasting conditions. On days one and seven, serial blood samples were collected from each subject prior to the daily dosing and up to 24 hours after dosing. Blood samples were also collected at 48, 72, 96 and 120 hours after initial dosing. Upon collection, the samples were promptly placed in an ice bath, and within 2 hours after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.
The results are summarized in Table 15A.

The relative bioavailability for a single dose of the once-daily (ER) tablet formulation (Regimen N) relative to the twice daily (IR) capsule formulation (Regimen M) was also determined based on analysis of the natural logarithms of Cmax, AUC24, Cmin, and C24. The results are summarized in Table 15B below.
The ratio of steady-state AUC for the 30 mg QD tablets relative to the 12 mg BID capsules was approximately 1, with the 90% confidence intervals within the equivalence boundaries. The steady-state Cmin for the 30 mg QD tablet was approximately 13% lower than for the 12 mg BID capsules. Outliers with high Cmin in the 12 mg BID dose may have contributed to this difference.
The pre-morning dose trough concentration (Ctrough) for the 12 mg BID capsules and 30 mg QD tablets was determined prior to the morning dose on Days 2-8. The results show that, at steady state under fasting conditions, the 30 mg QD tablets provided equivalent AUC24 and comparable Cmax and Cmin relative to the 12 mg BID capsules. The steady state Cmax was 10% lower for the 30 mg QD tablet compared to the 12 mg BID capsules.
The pharmacokinetic profile of the 6 mg immediate release (IR) twice daily (BID) capsules and the 12 mg IR twice daily capsules was determined on Day 7 of Regimen K (Example 26) and Regimen M (Example 27), respectively, after administration of the morning (AM dose) and evening (PM dose). The results are summarized in Table 16.

The pharmacokinetic profiles of the 30 mg once-daily extended release (ER) tablets that were prepared in Examples 14 (ER10, 30% tartaric acid), 15 (ER11, 20% tartaric acid), and 16 (ER12, 10% tartaric acid) using wet granulation were evaluated, and compared to that of the 30 mg ER tablet that was prepared in Example 8 (ER8, 30% tartaric acid) using direct compression (no wet granulation). The effect of a high-fat meal on the Example 14, 15, and 16 formulations was also evaluated.
Healthy human subjects (n=36) were administered a single dose of the 30 mg ER (once daily) tablet from Example 8 (ER8), Example 14 (ER10), Example 15 (ER11), and Example 16 (ER12) under fasting conditions or after a high-fat meal (non-fasting), in an open-label, randomized, four-period, incomplete crossover study. Doses in the four periods were separated by at least four days. Dosing regimens were as set forth below in Table 17A.
Serial blood samples were collected from each subject prior to dosing and for 72 hours after dosing in each study period. Upon collection, the samples were promptly placed in an ice bath, and within 1 hour after sample collection they were centrifuged at about 4° C. The resulting plasma samples were placed in clean polypropylene-tubes and stored in a freezer until analysis. The plasma samples were assayed for Compound 1 using appropriate liquid chromatography mass spectrometry procedures. Pharmacokinetic parameters were estimated using non-compartmental methods, and summary statistics were computed for each parameter by regimen.

The relative bioavailability for a single dose of the three once-daily (ER) tablet formulations prepared using wet granulation (Regimens B, D, and F) relative to the ER tablet prepared via direct compression (no wet granulation) (Regimen A) was also determined based on analysis of the natural logarithms of Cmax, AUCt, and AUCinf. The results are summarized in Table 17C below.
As can be seen from this data, all three of the 30 mg tablets prepared using wet granulation (ER10, ER11, and ER12) were bioequivalent under fasting conditions to the tablet prepared via direct compression (no wet granulation).

The results are summarized in Table 17G below.
As can be seen from this data, a high-fat meal increased the Cmax and AUCinf for the ER11 formulation (30 mg active, 20% tartaric acid) by about 34% and 29%, respectively, which was a similar food effect as that observed for the Example 14 (ER10) tablet.

As can be seen from this data, a high-fat meal increased the Cmax and AUCinf for the ER12 formulation (30 mg active, 10% tartaric acid) by about 53% and 27%, respectively.
The mean pharmacokinetic parameters under fasting conditions for the once daily (QD) 15 mg extended release tablets prepared in Examples 17 (ER13), 18 (ER14), and 19 (ER15) using wet granulation were extrapolated from the single dose data obtained in Example 29 for the Examples 14 (ER10), 15 (ER11), and 16 (ER12) formulations, respectively, under fasting conditions.

SELECT-AXIS 1 is a multicentre, randomised, double-blind, parallel-group, placebo-controlled, Phase 2/3, two-period study of upadacitinib (
Period 1 is the 14-week randomized, double-blind, parallel-group, placebo-controlled period designed to compare the safety and efficacy of upadacitinib free base 15 mg QD (once daily) versus placebo for the treatment of signs and symptoms of subjects with active AS who have had an inadequate response to at least two NSAIDs over an at least 4-week period in total at maximum recommended or tolerated doses or intolerance to or a contraindication for NSAIDs, and who are biologic Disease Modifying Anti-Rheumatic Drug (bDMARD)-naïve.
Period 2 is an open label long-term extension to evaluate the long-term safety, tolerability, and efficacy of upadacitinib free base 15 mg QD in subjects with AS who have completed Period 1.
X-rays of the pelvis were performed within the 35-day screening period to evaluate the SI joints to confirm the fulfillment of the modified New York Criteria for AS. X-rays of the spine were also performed within the 35-day screening period to assess for total spinal ankylosis; subjects with total spinal ankylosis were not eligible for this study. The x-rays of the spine and pelvis were not required during the Screening Period if the subject had a previous anteroposterior (AP) pelvis x-ray and lateral spine x-rays within 90 days of the Screening Period, provided that the x-rays are confirmed to be adequate for the required evaluations and are deemed acceptable by the central imaging vendor.
Subjects who met eligibility criteria were randomized in a 1:1 ratio to one of two treatment groups:
Starting at Week 16, subjects who did not achieve at least an ASAS 20 response at two consecutive visits had the option to add or modify doses of NSAIDs, acetaminophen/paracetamol, low potency opioid medications (tramadol or combination of acetaminophen and codeine or hydrocodone), and/or modify dose of MTX or SSZ at Week 20 or thereafter.
Starting at Week 24, subjects who still did not achieve at least an ASAS 20 response at two consecutive visits were discontinued from study drug treatment.
Subjects who completed the Week 14 visit (end of Period 1) entered the open-label long-term extension portion of the study, Period 2 (90 weeks). Subjects who were assigned to Upadacitinib in Period 1 continued to receive Upadacitinib free base 15 mg QD in an open-label manner. Subjects who were randomized to placebo at Baseline also received open-label upadacitinib free base 15 mg QD at Week 14.
The primary efficacy endpoint is ASAS 40 response at Week 14.
The key multiplicity adjusted secondary efficacy endpoints at Week 14 are:
Additional key secondary endpoints are:
Additional endpoints are the following measurements assessed in subjects treated with upadacitinib versus placebo at scheduled time points other than those specified for the primary and key secondary variables:
For each protocol-specified study visit, a target study day will be identified to represent the corresponding visit along with a window around the target day. Windows will be selected in a non-overlapping fashion so that a collection date does not fall into multiple visit windows. If a subject has two or more actual visits in one visit window, the visit closest to the target day will be used for analysis. If two visits are equidistant from the target day, then the later visit will be used for analysis.
The planned sample size of 170 for this study (with 1:1 randomisation ratio) was determined to provide ≥90% power for detecting a 26% difference in ASAS40 response rate (assuming a placebo ASAS40 response rate of 20%). Power and sample size calculations were performed at a two-sided significance level of 0.05 accounting for a 10% dropout rate. The full analysis set included all randomised patients who received at least one dose of study drug. The safety analysis set included all patients who received at least one dose of study drug. The SPARCC MRI assessment population was pre-specified in the statistical analysis plan (baseline included MRI data ≤3 days after first dose of study drug, and week 14 included MRI data up to first dose of Period 2 study drug; first dose in Period 2 was at week 14). A supplemental post hoc SPARCC MRI analysis was conducted to include all MRI data collected at nominal visits at baseline and week 14. Cumulative probability plots were generated to illustrate MRI SPARCC score changes on a patient level.
In the full analysis set, the primary endpoint was compared between the upadacitinib and the placebo group using the Cochran-Mantel-Haenszel test, adjusting for the stratification factor of screening hsCRP level. Non-responder imputation was used for handling missing data. Similar analyses as for the primary endpoint were conducted for secondary efficacy binary endpoints. For continuous secondary efficacy endpoints, comparisons between the upadacitinib and the placebo group were performed using mixed model for repeated measures with treatment group, visit, and treatment-by-visit interaction as fixed effects and the corresponding baseline value and the stratification factor of screening hsCRP level as the covariates. In order to preserve the overall type I error rate at α=0.05 level, a step-down approach was used to test the primary and multiplicity-controlled key secondary endpoints. The testing sequence includes a group of endpoints tested by the Hochberg procedure, including BASDAI50, ASQoL, ASAS PR, BASFI, BASMI, MASES, and WPAI (
Between Oct. 24, 2017, and Sep. 10, 2018, 395 patients were assessed for eligibility, and 187 were enrolled into the study. Of the 395 patients screened, 208 (52.7%) did not meet eligibility criteria and were excluded from the study (main reason for screening failure was not meeting the radiographic criterion of the modified New York criteria for AS). The remaining 187 patients who met eligibility criteria were randomised to placebo (n=94) or upadacitinib (n=93). Overall, 95.2% of patients completed Period 1 through week 14 on study drug (placebo, 89/94 [94.7%]; upadacitinib, 89/93 [95.7%]); one patient in the placebo group discontinued study drug but completed Period 1 visits. The most common primary reason for study drug discontinuation by week 14 were adverse events in the placebo group (n=3 [3.2%]) and adverse events (n=2 [2.2%]) and withdrawal of consent (n=2 [2.2%]) in the upadacitinib group.
Mean age was 45.4 years, mean duration from onset of symptoms was 14.4 years, and mean duration since diagnosis was 6.9 years. Most patients were male (132 [70.6%]), were human leukocyte antigen (HLA) B27 positive (143 [76.5%]) and were receiving concomitant NSAIDs at baseline (150 [80.2%]). Baseline disease characteristics were generally balanced between the two groups. Key demographics and baseline characteristics of the patients are summarized in the below Table 19B.

The study met its primary endpoint, with statistically significantly more patients treated with upadacitinib versus placebo achieving ASAS40 response at week 14 (48/93 [51.6%] vs 24/94 [25.5%]; p=0.0003) with a treatment difference (95% CI) of 26.1% (12.6-39.5%) (
For the other multiplicity-controlled key efficacy endpoints, statistical significance based on multiplicity adjustment was not met per the Hochberg procedure. Consistent improvement was observed in patients receiving upadacitinib versus placebo with nominal p values <0.05 for MASES (p=0.0488), BASMI (p=0.0296), ASQoL (p=0.0156), and ASAS HI (p=0.0073) at week 14, except for WPAI (

The proportions of patients who achieved ASDAS LDA, ASDAS ID, ASDAS CII, and ASDAS MI were greater (nominal p<0.0001) for upadacitinib versus placebo at week 14 (
apost-hoc analysis
Patients treated with the upadacitinib 15 mg QD dose showed greater improvement in back pain as assessed by the Total Back Pain component of ASAS response compared to placebo at Week 14. Improvement in the overall level of neck, back, or hip pain was demonstrated using BASDAI Question 2. Improvements were also demonstrated for peripheral pain and swelling (assessed by BASDAI question 3 on overall pain in joints other than in the neck, back, or hips) and nocturnal back pain. Improvements in total and nocturnal back pain were observed as early as Week 2.
No serious infections, herpes zoster, malignancy, venous thromboembolic events, or deaths were reported in Period 1. The proportion of patients with adverse events was higher in the upadacitinib group 58/93 (62.4%) versus placebo group 52/94 (55.3%). One serious adverse event in each group was reported during Period 1: cardiovascular disorder/circulation dysregulation in the placebo group (patient was not feeling well and was hospitalised but no significant findings were obtained) and worsening of spinal osteoarthritis in the upadacitinib group in a patient with a history of spondylosis and disc protrusion in the cervical spine. The proportion of patients with adverse events leading to discontinuation of study drug (upadacitinib, 2/93 [2.2%]; placebo, 3/94 [3.2%]) and infections (upadacitinib, 19/93 [20.4%]; placebo, 26/94 [27.7%]) was similar for both treatment groups. The most common adverse event in patients in the upadacitinib group was blood creatine phosphokinase (CPK), which increased (8/93 [8.6%] vs 2/94 [2.1%] patients in the placebo group), with four events (vs one with placebo) assessed by the investigator to be possibly related to study drug; all patients were asymptomatic with elevations <4×ULN, except for one patient in the placebo group with muscle pain and an increase to 4.3×ULN. Most of these events were reversible without study drug interruption (6/8 with upadacitinib, 1/2 with placebo). One patient in the upadacitinib group who already had grade 2 neutropenia at baseline experienced a mild adverse event of grade 2 neutropenia.
Seven patients reported hepatic disorder adverse events (upadacitinib, 5/93 [5.4%]; placebo, 2/94 [2.1%]); none resulted in study drug discontinuation, and all were asymptomatic alanine aminotransferase or aspartate aminotransferase increases, with associated elevations <2×ULN in 6/7 and an elevation <3×ULN in the remaining patient. No differences in mean haemoglobin levels were observed throughout the 14-week period in either group.
Increases from baseline to week 14 in low-density lipoprotein cholesterol (0.318 mmol/L) and high-density lipoprotein (HDL) cholesterol (0.263 mmol/L) were observed in the upadacitinib group versus the placebo group (−0.083 and 0.010 mmol/L, respectively); however, no changes in the total cholesterol/HDL ratio were observed (upadacitinib, −0.071 mmol/L; placebo, −0.083 mmol/L).
The SELECT-AXIS 1 is the first clinical trial of upadacitinib in AS and demonstrated consistent efficacy results supported by multiplicity-controlled endpoints. The study met its primary endpoint of ASAS40 response at week 14 (51.6% vs 25.5%) as well as several multiplicity-controlled secondary endpoints reflecting statistically significant improvement in disease activity (ASAS PR, BASDAI50, ASDAS), function (BASFI), and MRI outcomes (SPARCC MRI spine). The other multiplicity-controlled secondary endpoints did not meet significance in the multiplicity testing but demonstrated consistent improvements for ASQoL, BASMI, MASES, and ASAS HI, with upadacitinib versus placebo (nominal p<0.05), with the exception of WPAI.
A rapid onset of response to upadacitinib free base 15 mg QD treatment was observed for ASAS40 and ASDAS composite scores and their individual domains of disease activity (e.g., back pain, PtGA, morning stiffness, function, and serum markers of inflammation [hsCRP]), with responses observed as early as week 2 (first post-baseline visit) and consistently maintained through week 14. The results of upadacitinib on improving the signs and symptoms of AS are further confirmed by a significant reduction of active inflammation on MRI for both the spine and the SI joints.
In addition, outcomes related to clinically relevant treatment goals of remission or low disease activity, such as ASDAS ID or LDA, were also achieved, with 50% of patients reaching ASDAS LDA (difference vs placebo, 39%). See, e.g., Smolen et al., Ann Rheum Dis 2018; 77: 3-17. Of note, the placebo response rates for ASAS20 and ASAS40 in this study were similar to rates observed in recent clinical studies of AS; differences in ASAS40 response with upadacitinib versus placebo were p<0.05 (based on nominal p values) as early as week 2 and maintained throughout 14 weeks. See e.g., van der Heijde et al., Ann Rheum Dis 2017; 76: 1340-47; van der Heijde et al., Lancet 2018; 392: 2378-87; van der Heijde et al., Lancet 2018; 392: 2441-51; Landewe et al., Ann Rheum Dis 2014; 73: 39-47. Interestingly, mean changes from baseline to week 14 in the MRI SPARCC scores for the spine and SI joints in the placebo group were quite small.
The study results are in line with findings from two Phase 2/3 JAK inhibitor studies in patients with active AS. See, e.g., van der Heijde et al., Ann Rheum Dis 2017; 76: 1340-47; van der Heijde et al., Lancet 2018; 392: 2378-87. Together with these findings, the SELECT-AXIS 1 results further support that JAK inhibitors could represent an effective treatment option for AS. Currently, only TNF-α and IL-17 inhibition have been proven to be effective in axSpA; but, these cytokines are not directly blocked by JAK inhibitors including upadacitinib. See, e.g., Furst and Louie, Arthritis Res Ther 2019; 21: 135. However, emerging data from upadacitinib RA studies suggest that selective inhibition of JAK1 may result in the secondary inhibition of additional pathways that do not depend on JAK1 signalling, such as TNF-α and IL-12. See, e.g., Sornasse et al., Ann Rheum Dis 2019; 78: 365-66. Also, other JAK1-associated pathways, including IL-7 and IL-22, have been described in preclinical studies, but further research is needed to evaluate the mechanism of action of JAK inhibitors in axSpA. See, e.g., Veale et al., Rheumatology (Oxford) 2019; 58: 197-205; Gracey et al., Ann Rheum Dis 2016; 75: 2124-32.
The proportion of patients with adverse events was generally similar in the upadacitinib and placebo groups, and no new safety findings were observed compared with previous upadacitinib phase 3 RA studies. See, e.g., Burmester et al., Lancet 2018; 391: 2503-12; Genovese et al., Lancet 2018; 391: 2513-24; Fleischmann R, Pangan A L, Song I, et al. Upadacitinib versus placebo or adalimumab in patients with rheumatoid arthritis and an inadequate response to methotrexate: results of a phase 3, double-blind, randomized controlled trial. Arthritis Rheumatol 2019; doi: 10.1002/art.41032. [Epub ahead of print]; Cohen et al., Ann Rheum Dis (2019) 78. No serious infections, malignancies, anaemia, lymphopenia, herpes zoster, renal dysfunction, adjudicated major adverse cardiovascular events, venous thromboembolic events, or deaths were reported, and haemoglobin levels remained consistent throughout the study.
A higher proportion of patients in the upadacitinib group experienced adverse events of CPK elevation, all of which were asymptomatic and most were mild and reversible without study drug interruption. One patient in the placebo group experienced symptoms (muscle pain) in the setting of elevated CPK and permanently discontinued study drug. In the two previous JAK inhibitor studies, elevations in CPK were also observed. See e.g., van der Heijde et al., Ann Rheum Dis 2017; 76: 1340-47; van der Heijde et al., Lancet 2018; 392: 2378-87. Additional data are needed to better understand the safety profile of upadacitinib in axSpA.
JAK inhibitors, such as upadacitinib, could help address the unmet need in axSpA treatment given that only approximately half of bDMARD-naive patients achieve an ASAS40 response and even less achieve remission with TNF or IL-17 inhibitor treatment. See, e.g., Sieper et al., Ann Rheum Dis 2017; 76: 571-92; Deodhar et al., Arthritis Rheumatol 2019; 71: 599-611; van der Heijde et al., Lancet 2018; 392: 2441-51; Landewe et al., Ann Rheum Dis 2014; 73: 39-47; Lie E et al., Ann Rheum Dis 2011; 70: 157-63; Glintborg et al., Ann Rheum Dis 2013; 72: 1149-55. Furthermore, fewer patients are expected to achieve the treatment goal of sustained remission/LDA, and response rates are even lower in patients with AS who have not responded to bDMARD therapy. See, e.g., Sieper et al., Lancet 2017; 390: 73-84; Sieper et al., Ann Rheum Dis 2017; 76: 571-92; Deodhar et al., Arthritis Rheumatol 2019; 71: 599-611. Furthermore, some patients with axSpA may not be eligible for or might have contraindications common to IL-17 and TNF inhibitor therapy, such as allergic reactions and injection site pain, or specific to TNF inhibitors, such as congestive heart failure and concomitant demyelinating disease. See, e.g., Cortese et al., Mult Scler Relat Disord 2019; 35: 193-95. The use of IL-17 inhibitors is also not recommended for patients with concomitant inflammatory bowel disease. See, e.g., van der Heijde et al., Ann Rheum Dis 2017; 76: 978-91; Fragoulis et al., World J Gastroenterol 2019; 25: 2162-76. Because patients with AS are typically younger and may have more active lifestyles, a treatment option administered orally may be particularly important in this patient population. See e.g., Alten et al., Patient Prefer Adherence 2016; 10: 2217-28. Considering these unmet needs, the findings of the SELECT-AXIS 1 study, which demonstrated that upadacitinib treatment effects are within the range observed with bDMARDs and other JAK inhibitors in AS, support further investigation of upadacitinib for AS. See, e.g., Sieper et al., Ann Rheum Dis 2017; 76: 571-92; Deodhar et al., Arthritis Rheumatol 2019; 71: 599-611; van der Heijde et al., Ann Rheum Dis 2017; 76: 1340-47; van der Heijde et al., Lancet 2018; 392: 2378-87; van der Heijde et al., Lancet 2018; 392: 2441-51; Landewe et al., Ann Rheum Dis 2014; 73: 39-47.
This study is not without limitations. The focus on patients with AS who were bDMARD-naive allowed for a focused evaluation of benefit and risk in a homogeneous population, but the safety and efficacy of upadacitinib in patients with AS who are bDMARD-IR or in patients with non-radiographic axSpA has not yet been evaluated, and further studies are needed in these patient populations. Furthermore, only one dose of upadacitinib was evaluated in this study, and thus there are no data to confirm whether a higher dose could have resulted in greater efficacy. Lastly, only 14-week, short-term data are reported here, but the long-term efficacy and safety of upadacitinib will be collected in the ongoing SELECT-AXIS 1 extension period for up to 2 years.
In conclusion, oral upadacitinib free base 15 mg QD significantly improved disease activity, function, and MRI-detected axial inflammation in patients with active AS after 14 weeks of treatment. The incidence of adverse events was similar with upadacitinib and placebo, and no new safety signals were observed compared with previous studies in RA. Overall, these results support the further investigation of upadacitinib for the treatment of AS/axSpA.
The phase 2/3 SELECT-AXIS 1 study included a randomized, placebo-controlled, 14-week period followed by 90-week open-label extension; reported here are data through week 64.
The study enrolled adults (≥18 years) with active AS who had an inadequate response to ≥2 non-steroidal anti-inflammatory drugs therapy (or intolerance to or contraindication for NSAIDs) and were biologic disease-modifying antirheumatic drugs naïve, and who met the modified New York criteria based on independent central reading of radiographs of the sacroiliac joints and who had active disease at baseline defined as Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score ≥4 and patient's assessment of back pain score ≥4 (numeric rating scale [NRS], 0-10) at screening and baseline visit. Patients receiving a stable dose of concomitant conventional synthetic disease-modifying antirheumatic drugs (DMARDs), oral glucocorticoids, NSAIDs and analgesics were eligible; patients with prior exposure to JAK inhibitors or biologic DMARDs with potential impact on spondyloarthritis were excluded. Of the 187 patients randomized to Period 1, 178 (continuous upadacitinib, n=89; placebo switch, n=89) completed week 14 on study drug and entered the open-label extension; 160 patients (continuous upadacitinib n=78 [83.9%]; placebo switch, n=82 [87.2%]) completed week 64. Lack of efficacy (n=10) and AEs (n=4) were the most common reasons for discontinuation of study drug between weeks 14 and 64. In the continuous upadacitinib and the placebo-to-upadacitinib switch groups, mean duration since AS symptom onset was 14.8 and 14.0 years, mean duration since diagnosis was 7.8 and 6.0 years, mean ASDAS was 3.5 and 3.7, and mean hsCRP levels were 9.6 and 11.4 mg/L, respectively. Concomitant medications included NSAIDs (76% and 86%), conventional synthetic DMARDs (14% and 18%), and glucocorticoids (6% and 13%, respectively).
Efficacy was assessed based on percentage of patients achieving ASAS20 response, ASAS40 response, ASAS partial remission, BASDAI50, and Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease (ID; <1.3), low disease activity (LDA; <2.1), major improvement (MI; decrease from baseline ≥2.0), and clinically important improvement (CII; decrease from baseline ≥1.1) through 64 weeks. In addition, change from baseline in ASDAS based on C-reactive protein (ASDAS-CRP), Bath Ankylosing Spondylitis Functional Index (BASFI), and linear Bath Ankylosing Spondylitis Metrology Index (BASMI) through 64 weeks and Maastricht Ankylosing Spondylitis Enthesitis Score (MASES), Work Productivity and Activity Impairment (WPAI; on a scale of 0-100), ASAS Health Index (HI), and AS quality of life (ASQoL) through 52 were assessed.
ASAS20 and ASAS40 responses were defined as ≥20% or ≥40% improvement and an absolute improvement of ≥1 or ≥2 units (on an NRS scale of 0-10), respectively, from baseline in ≥3 of the following 4 domains (with no worsening of ≥20% and ≥1 unit or no worsening at all, respectively, in the remaining domain): Patient Global Assessment of disease activity (PtGA), patient assessment of back pain, BASFI, and inflammation defined as the mean of BASDAI questions 5 and 6 (severity and duration of morning stiffness). ASAS partial remission was defined as an absolute score of ≤2 units for each of the 4 domains identified for ASAS40 response. ASDAS-CRP consists of patient-reported outcomes about back pain (BASDAI item 2), peripheral pain/swelling (BASDAI item 3), duration of morning stiffness (BASDAI item 6), the PtGA, and CRP.
The percentage of patients achieving the primary efficacy endpoint of ASAS40 at week 14 continued to increase throughout the study in the continuous upadacitinib group: 85% (95% CI, 77%-93%) of patients achieved ASAS40 at week 64 in the as-observed analysis and 72% (63%-81%) in the NRI analysis (
Mean changes from baseline to 1 year in disease activity (ASDAS), physical function (BASFI), patient assessment of pain and disease activity (PtGA), and inflammation (hsCRP) showed consistent improvement or sustained maintenance throughout the study in the continuous upadacitinib group; a similar magnitude of improvement was seen in the placebo-to-upadacitinib switch group after initiation of upadacitinib at week 14. Analogous patterns of improvement were shown in assessments of quality of life (ASQoL and ASAS HI), spinal mobility (BASMI), and enthesitis (MASES) over time, as well as in measurements of back pain, nocturnal back pain, BASDAI Q2 (back pain) and BASDAI Q5/6. Among patients who were employed at baseline, the mean (95% CI) WPAI overall work impairment score continued to improve throughout the study in the continuous upadacitinib group (from −20.5 [−27.1, −14.0] at week 14 to −35.6 [−43.2, −28.0] at week 52; as-observed analysis) and placebo-to-upadacitinib switch group (from −12.3 [−19.8, −4.8] at week 14 to −27.7 [−35.4, −20.0] at week 52).
A significantly higher proportion of patients receiving upadacitinib versus placebo achieved ≥30% and ≥50% reduction in Patient's Global Assessment (PGA) of pain and back pain as early as week 2, and ≥70% reduction as early as week 4, and efficacy achieved was sustained thereafter. See, e.g.,
Upadacitinib as a Promising Oral Therapy in AS and nr-AxSpA
SELECT-AXIS 1, the first study to report long-term data with a JAK inhibitor in AS, showed that upadacitinib 15 mg QD therapy led to sustained and consistent efficacy up to and including Week 64 in both NRI and as-observed analyses in patients with active AS who had an inadequate response to NSAIDs. Improvements were seen in disease activity measures (ASDAS, BASDAI, ASAS, and their components), inflammation (hsCRP), physical function (BASFI), quality of life (ASQoL, ASAS HI), and other aspects of disease (BASMI, MASES) with continuous upadacitinib therapy. In patients who switched from placebo to upadacitinib at week 14, a similar speed of onset and magnitude of efficacy response was observed up to and including Week 64 compared with those who received continuous upadacitinib starting at Week 0. Of note, approximately 40%-45% of patients receiving upadacitinib reached remission based on the more difficult to achieve endpoints ASAS partial remission (PR) or ASDAS inactive disease (ID) up to and including Week 64, and >80% were in a state of ASDAS low disease activity (LDA).
The below Table 19E provides placebo corrected data for upadacitinib at Week 14, biologics Ixekizumab and Adalimumab at Week 16, and JAK small molecule inhibitors Tofacitinib and Filgotinib at Week 12 for key primary and secondary endpoints. While this data is not a head to head comparison, the placebo corrected response calculated for upadacitinib for the more difficult to achieve endpoints ASAS PR, ASDAS ID, and ASDAS LDA shows decided promise over the efficacy demonstrated by the other two JAK small molecule inhibitors, with a remarkable efficacy only comparable to that demonstrated with the biologics. Furthermore, this efficacy, once achieved at Week 14, was sustained or improved over time, with long term efficacy in these difficult to achieve endpoints (including ASDAS major improvement (MI) and ASDAS clinically important improvement (CII)), sustained or improved up to and including Week 64. Coupled with the fact that upadacitinib is well tolerated with no new or unexpected safety findings (particularly compared to the other JAK inhibitors), the data suggests upadacitinib will be a promising new safe oral therapy for AS patients, especially for those AS patients who have active disease and inadequate response to NSAIDs.
The safety and efficacy data from the Phase 2/3 study (as described in U.S. Pat. App. No. 2021/0228575) show a favorable benefit:risk profile for upadacitinib and support the continued investigation of upadacitinib in adult subjects with active axSpA who had an inadequate response to biologic disease-modifying anti-rheumatic drug therapy (bDMARD-IR) (Study 1; Example 32) and in adult subjects with active nr-axSpA (Study 2; Example 33). The Phase 3 clinical study plan is set forth in
Adult Subjects with Active Ankylosing Spondylitis (AS) Who had an Inadequate Response to Biologic Disease-Modifying Anti-Rheumatic Drug Therapy (bDMARD-IR) (Study 1)
Study 1 is a Phase 3, randomized, placebo-controlled, double-blind multicenter study to evaluate the safety, tolerability, and efficacy of upadacitinib compared with placebo on reduction of signs and symptoms in adult subjects with active ankylosing spondylitis (AS) who had an inadequate response to biologic disease-modifying anti-rheumatic drug therapy (bDMARD-IR).
Study 1 (main study) is comprised of a 35-day Screening Period; a 14-week randomized, double-blind, parallel-group, placebo-controlled period (the Double-Blind Period) designed to compare the safety and efficacy of upadacitinib freebase 15 mg QD versus placebo for the treatment of signs and symptoms of subjects with active AS who have an inadequate response to bDMARD therapy; and a 90-week open-label, long-term extension period (the Open-Label Extension Period) to evaluate the long-term safety, tolerability, and efficacy of upadacitinib free base 15 mg QD in subjects who have completed the Double-Blind Period up to Week 104 (see
Subjects in Study 1 who reach Week 104 on study drug (upadacitinib free base 15 mg QD) will be assessed whether they are in remission. Subjects in remission at Week 104 will be eligible for the Remission-Withdrawal Period. Subjects will be followed without study drug treatment and assessed for disease flare through Week 152. Subjects who flare will receive open-label upadacitinib free base 15 mg QD from the time of flare for 24 weeks (re-treatment) or longer.
Subjects were enrolled from 119 sites in 22 countries. Eligible subjects were adult females and males who were at least 18 years of age at Screening with a clinical diagnosis of AS, met the modified New York Criteria for AS, and were without total spinal ankylosis. Eligible study subjects must have had a Bath Ankylosing Spondylitis Disease Activity Index score ≥4 and a Patient's Assessment of Total Back Pain score (Total Back Pain score) ≥4 based on a 0-10 numerical rating scale at the Screening and Baseline Visits.
Subjects were randomized in a 1:1 ratio to one of two treatment groups, stratified by screening hsCRP (≤ULN vs >ULN), the class of prior bDMARD use (1 TNF, 1 IL-17, other) and geographic region:
The primary endpoint was the proportion of subjects achieving an ASAS40 response at Week 14. Secondary endpoints for Study 1 are described below.

The key multiplicity-controlled secondary endpoints at Week 14 are as follows:
Additional key secondary endpoints at Week 14 include: Change from Baseline in MRI SPARCC score (SI joints).
Additional endpoints are the following measurements assessed at time points other than those specified for the primary and key secondary variables are as follows:
A total of 420 subjects were randomized in Study 1 and received double blind study drug treatment, out of which 409 (97.4%) completed study drug through Week 14. The rates of premature discontinuation of study drug were low and similar in the placebo group and the upadacitinib treatment group (Table 20C). The key demographics and baseline characteristics were balanced across the treatment groups and generally consistent with the targeted patient population (Table 20D).

In this Phase 3 AS bDMARD-IR study, the safety profile of upadacitinib freebase was consistent with what is known for upadacitinib, and no new risks were identified.
The overview of TEAEs and AESIs up to Week 14 are summarized in Table 20F and Table 20G respectively. The rate of overall AEs was similar between the upadacitinib freebase 15 mg and placebo groups. Up to Week 14, there were no events of malignancy, adjudicated GI perforation, adjudicated MACE, or adjudicated VTE reported in subjects receiving upadacitinib freebase. There was one malignancy observed in the placebo group. Serious AEs were reported more frequently with upadacitinib freebase 15 mg, the majority of which were COVID-19 or COVID-19 pneumonia. For AEs leading to discontinuation of study drug, none were reported with upadacitinib 15 mg compared to 3 (1.4%) with placebo. No deaths were reported.
Serious infections and herpes zoster were reported with upadacitinib 15 mg (2.4% and 0.9%, respectively). Four of the 5 serious infections were COVID-19 or COVID-19 pneumonia. Both herpes zoster events were nonserious, did not lead to treatment discontinuation, and involved a single dermatome.
One event of tonsil cancer was reported in a subject receiving placebo. No malignancy was reported with upadacitinib 15 mg.
All hepatic disorders reported in the upadacitinib group were mild or moderate transaminase elevations; none were serious or led to discontinuation of treatment.
AEs of anemia, neutropenia, and lymphopenia were generally mild or moderate, nonserious, and did not lead to treatment discontinuation.
There were no events of opportunistic infection, non-melanoma skin cancer, lymphoma, adjudicated GI perforation, renal dysfunction, active tuberculosis, adjudicated MACE or VTE reported.
More COVID-19 related infections were reported with upadacitinib compared to placebo. None of the infections led to discontinuation of study drug.
Through week 14, the most common adverse events (≥3% of patients) for RINVOQ were COVID-19 and headache. The proportion of patients with adverse events leading to discontinuation, serious adverse events and serious infections were 0 percent/2.8 percent/2.4 percent for RINVOQ and 1.4 percent/0.5 percent/0 percent for placebo, respectively. Serious infections included four events of COVID-19 and one of uveitis with RINVOQ; two patients on RINVOQ developed non-serious, mild or moderate herpes zoster limited to one dermatome. One patient treated with placebo developed a malignancy (tonsil cancer). No adjudicated major adverse cardiovascular events, venous thromboembolic events or deaths were reported in either group through week 14.
$As assessed by investigator.
Potentially clinically significant lab and vital sign abnormalities were reported infrequently (Table 20H). There was no Hy's law case in this study up to Week 14.
aGrading is based CTCAE V4 criteria; Grade must be worse than the baseline grade to be counted
Overall, the results from Study 1 support planned regulatory submissions in the AS indication. In bDMARD-IR population, upadacitinib demonstrated significantly greater improvements in AS signs and symptoms of AS, including back pain and inflammation, as well as improvements in physical function, disease activity, mobility, and quality of life compared to placebo at Week 14.
Additionally, significantly more patients treated with the upadacitinib freebase 15 mg QD achieved ASDAS Low Disease Activity (LDA) compared to those treated with placebo (44 percent versus 10 percent). A statistically significantly greater improvement in Magnetic Resonance Imaging (MRI) Spondyloarthritis Research Consortium of Canada (SPARCC) Score (Spine) as measured by mean change from baseline was reported in the treatment group versus the placebo group (−3.95 versus −0.04). Patients in the treatment group experienced a significantly greater mean decrease from baseline in Patient's Assessment of Total Back Pain at week 14 than those on placebo (−3.00 versus −1.47). Additionally, patients in the treatment group experienced significantly greater improvement in physical function as assessed by mean change from baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) compared to patients on placebo (−2.26 versus −1.09). All ranked secondary endpoints achieved p-values of <0.0001 versus placebo. Additional results are summarized below in Table 201.
aASAS 40 is defined as a ≥40 percent improvement and an absolute improvement of ≥2 units (on a scale of 0 to 10) from Baseline in at least 3 of the 4 domains (patient's global assessment, back pain, function, and inflammation) with no worsening at all in the remaining domain.
bASDAS Low Disease Activity is defined as ASDAS score <2.1.
cSPARCC scores for spine are calculated by adding up the dichotomous outcomes from evaluations of the presence, depth, and intensity of bone marrow edema lesions of the spine.
dBack Pain is measured using 0-10 numerical rating scale (NRS) for Total Back Pain (0 = no pain and 10 = severe pain).
eBASFI is a validated patient-reported outcome (PRO) instrument for use in the AS patient population. It consists of 10 items measured on a 0 to 10 NRS, which assesses the ability to perform activities known to be problematic to AS patients such as dressing, bending, reaching, turning, and climbing steps. The total scores range from 0 to 10.

The Phase 3 clinical study plan is set forth in
Adult Subjects with Active Non-Radiographic Axial Spondyloarthritis (Nr-axSpA) (Study 2)
Study 2 is a Phase 3, randomized, placebo-controlled, double-blind multicenter study to evaluate the safety, tolerability, and efficacy of upadacitinib compared with placebo on reduction of signs and symptoms in adult subjects with active non-radiographic axial spondyloarthritis (nr-axSpA).
Study 2 (nr-axSpA) is comprised of a 35-day Screening Period; a 52-week randomized, double-blind, parallel-group, placebo-controlled period (the Double-Blind Period) designed to compare the safety and efficacy of upadacitinib freebase 15 mg QD versus placebo for the treatment of signs and symptoms of subjects with active nr-axSpA; and a 52-week open-label, long-term extension period (the Open-Label Extension Period) for evaluating the long-term safety, tolerability, and efficacy of upadacitinib freebase 15 mg QD in subjects who have completed the Double Blind Period up to week 104 (
Subjects in Study 2 who reach Week 104 on study drug (upadacitinib free base 15 mg QD) will be assessed whether they are in remission. Subjects in remission at Week 104 will be eligible for the Remission-Withdrawal Period. Subjects will be followed without study drug treatment and assessed for disease flare through Week 152. Subjects who flare will receive open-label upadacitinib 15 mg QD from the time of flare for 24 weeks (re-treatment) or longer.
Subjects in the placebo group will be switched to upadacitinib free base 15 mg QD at Week 52 in the Open-Label Extension Period for Study 2 (nr-axSpA).
Subjects were randomized in a 1:1 ratio to one of two treatment groups, stratified by MRI and screening hsCRP status (MRI+/hsCRP>ULN, MRI+hsCRP≤ULN, and MRI−/hsCRP>ULN), and exposure to bDMARDs (yes vs no):
Subjects were enrolled from 113 sites in 23 countries. Eligible subjects were adult females and males who were at least 18 years of age at Screening with a clinical diagnosis of nr-axSpA fulfilling the 2009 ASAS classification criteria for axSpA but not meeting the radiologic criterion of the modified New York criteria for AS and have objective signs of active inflammation on magnetic resonance imaging of sacroiliac joints or based on high sensitivity C-reactive protein >upper limit of normal (Study 2, nr-axSpA). Eligible study subjects must have had a Bath Ankylosing Spondylitis Disease Activity Index score ≥4 and a Patient's Assessment of Total Back Pain score (Total Back Pain score) ≥4 based on a 0-10 numerical rating scale at the Screening and Baseline Visits. Subject must have had objective signs of active inflammation on MRI of SI joints or hsCRP>ULN at screening.
For Study 2, subjects with prior failure of nonsteroidal anti-inflammatory drugs (NSAIDs) were enrolled, and prior treatment with at most 1 bDMARD (either 1 TNF inhibitor or 1 IL-17 inhibitor) was allowed in a subset of subjects (at least 25%, but not exceeding 35% of total enrolled subjects). Subjects with prior exposure to 1 bDMARD (either 1 tumor necrosis factor [TNF] inhibitor or 1 interleukin [IL]-17 inhibitor) may be enrolled, and the subject must have discontinued the bDMARD due to either intolerance or lack of efficacy. Prior exposure to a 2nd bDMARD was allowed for no more than 30% of subjects if the reason for discontinuation was not due to lack of efficacy. Subjects who have had lack of efficacy to both a TNF inhibitor and IL-17 inhibitor were not eligible.
The primary endpoint is the proportion of subjects achieving an ASAS40 response at Week 14.
Secondary endpoints for Study 2 are described below.
1. Subject must have a clinical diagnosis of nr-axSpA fulfilling the 2009 ASAS classification criteria for axSpA but not meeting the radiologic criterion of the modified New York criteria for AS.
2. Subjects with or without prior exposure to a bDMARD may be enrolled. For the subset of subjects with prior bDMARD exposure (at least 25%, but not exceeding 35% of total enrolled subjects), prior treatment with at most 1 bDMARD (either 1 TNF inhibitor or 1 IL-17 inhibitor) is allowed, and the subject must have discontinued the bDMARD due to either intolerance or lack of efficacy. Subjects who have had lack of efficacy to both a TNF inhibitor and IL-17 inhibitor were not eligible.
3. Subject must have objective signs of active inflammation on MRI of SI joints or hsCRP>ULN at screening.
1. Subject must be an adult male or female, at least 18 years of age at Screening.
2. Subject must meet the following scores at Screening and Baseline Visits: BASDAI score ≥4 and Total Back Pain score ≥4 based on a 0-10 NRS.
3. Subject has had an inadequate response to at least 2 NSAIDs over an at least 4-week period in total at maximum recommended or tolerated doses, or subject has an intolerance to or contraindication for NSAIDs.
4. The washout period for bDMARDs prior to the first dose of study drug is specified below:
The key multiplicity-controlled secondary endpoints at Week 14 were as follows:
Additional key secondary endpoints at Week 14 include: Change from Baseline in MRI SPARCC score (spine) at Week 14.
Additional endpoints are the following measurements assessed at time points other than those specified for the primary and key secondary variables are as follows:
A total of 314 subjects were randomized in Study 2 and 313 received double blind study drug treatment, out of which 295 (94.2%) completed study drug through Week 14. One subject randomized to the placebo group did not receive study drug. The rates of premature discontinuation of study drug through Week 14 were 4.5% and 7.1% in the placebo group and the upadacitinib treatment group respectively (Table 21C). The key demographics and baseline characteristics were balanced across the treatment groups and generally consistent with the targeted patient population (Table 21D).

The primary endpoint was the achievement of an ASAS40 response at Week 14. The primary analysis, using Non-Responder Imputation in conjunction with Multiple Imputation (NRI-MI) to handle missing data due to COVID-19, showed a statistically significantly higher response rate (p<0.0001) in the upadacitinib group (44.9%) as compared to placebo (22.5%) (
The first 12 of the 14 ranked endpoints at Week 14 were statistically significant. Details of the primary and ranked secondary endpoints are presented in Table 21E and
aResults for binary endpoints are based on NRI-MI analysis. Analyses for all continuous endpoints are for the change from baseline value. Results for continuous endpoints are based on MMRM, except for MRI and BASMI which use ANCOVA analysis.
bUnadjusted raw p-values are presented.
cSummarized for subjects with available baseline MRI data up to 3 days post first dose of study drug and available week 14 MRI data.
dSummarized for subjects with presence of enthesitis at baseline (N = 125 in Placebo, N = 124 in UPA).
In this Phase 3 nr-axSpA study, the safety profile of upadacitinib was consistent with what is known for upadacitinib and no new risks were identified.
The overview of TEAEs and AESIs up to Week 14 are summarized in Table 21F and Table 21G respectively. Through week 14, the most common adverse events (≥3% of patients) with upadacitinib were headache, COVID-19, nasopharyngitis, and nausea. The proportion of patients with adverse events leading to discontinuation, serious adverse events and serious infections were 2.6 percent/2.6 percent/1.3 percent for upadacitinib and 1.3 percent/1.3 percent/0.6 percent for placebo, respectively. Serious infections included COVID-19 induced pneumonia and pyelonephritis in two patients on upadacitinib and hemorrhagic fever with renal syndrome in one patient on placebo. Two patients treated with upadacitinib and one treated with placebo developed non-serious, mild or moderate herpes zoster limited to one dermatome. One patient treated with placebo developed a malignancy (basal cell carcinoma). No adjudicated major adverse cardiovascular events, venous thromboembolic events or deaths were reported in either group through week 14. In summary:
$As assessed by investigator.
Potentially clinically significant lab abnormalities were reported infrequently (Table 21H). There was no Hy's law case in this study up to Week 14.
aGrading is based CTCAE V4 criteria; Grade must be worse than the baseline grade to be counted
Overall, the topline results from Study 2 support planned regulatory submissions for the nr-axSpA indication.
Upadacitinib demonstrated significantly greater improvements (e.g., reductions) in nr-axSpA signs and symptoms, including back pain and inflammation, as well as improvements in physical function, disease acrivity, and quality of life compared with placebo at Week 14. Significantly more patients treated with upadacitinib achieved Ankylosing Spondylitis Disease Activity Score (ASDAS) Low Disease Activity compared to those treated with placebo (42 percent versus 18 percent; p<0.0001). A statistically significantly greater improvement in Magnetic Resonance Imaging (MRI) Spondyloarthritis Research Consortium of Canada (SPARCC) Score (SI Joints) as measured by mean change from baseline was reported in the upadacitinib group versus the placebo group (−2.49 versus 0.57; p<0.0001). Patients on upadacitinib experienced significantly greater decrease from baseline in Patient's Assessment of Total Back Pain at week 14 than those on placebo (−2.91 versus −2.00; p=0.0004). Additionally, patients treated with upadacitinib experienced significantly greater improvement in physical function as assessed by mean change from baseline in Bath Ankylosing Spondylitis Functional Index (BASFI) compared to patients on placebo (−2.61 versus −1.47; p<0.0001). Additional results are summarized in Table 21I below.
aASAS 40 is defined as a ≥40 percent improvement and an absolute improvement of ≥2 units (on a scale of 0 to 10) from Baseline in at least 3 of the 4 domains (patient's global assessment, back pain, function and inflammation) with no worsening at all in the remaining domain.
bASDAS Low Disease Activity is defined as ASDAS score <2.1.
cSPARCC scores for SI-Joints are calculated by adding up the dichotomous outcomes from evaluations of the presence, depth, and intensity of bone marrow edema lesions of the SI-joints.
dBackPain is measured using 0-10 numerical rating scale (NRS) for Total Back Pain (0 = no pain and 10 = severe pain).
eBASFI is a validated patient-reported outcome (PRO) instrument for use in the axial SpA patient population. It consists of 10 items measured on a 0 to 10 NRS, which assesses the ability to perform activities known to be problematic to axial SpA patients such as dressing, bending, reaching, turning, and climbing steps. The total scores range from 0 to 10.
