20240156840
The present patent application relates to a method of treating allergic rhinitis in a subject (preferably a human) by administering a combination of mometasone or its salt and olopatadine or its salt.
Allergic rhinitis is a medical term for inflammation and irritation of the mucous membrane inside the nose. It generally occurs when an allergen such as pollen, dust, or animal dander (particles of shed skin and hair) is inhaled by an individual with a sensitized immune system. Allergic rhinitis may cause additional symptoms such as rhinorrhea (excess nasal secretion), sneezing, nasal itching, nasal congestion and obstruction, coughing, headache, fatigue and malaise. Symptoms may vary in severity between individuals.
Many treatment options are available for treating allergic rhinitis such as, for example, antihistamines (e.g., cetirizine and loratadine), steroids (e.g., triamcinolone), decongestants, and leukotriene receptor antagonists (e.g., montelukast). These treatments are generally administered orally or nasally and some are associated with unpleasant taste and smell (e.g., Dymista® nasal spray, which is a combination of azelastine and fluticasone propionate).
Olopatadine hydrochloride, an antihistamine, is chemically described as (Z)-11-[3-(dimethylamino)propylidene]-6,11-dihydrodibenz[b,e]oxepin-2-acetic acid hydrochloride, and is disclosed in U.S. Pat. Nos. 4,871,865 and 4,923,892. It is commercially available in the United States as PATANASE® Nasal Spray, which contains 0.6% w/v olopatadine (base) in a non-sterile aqueous solution. It is indicated for the relief of the symptoms of seasonal allergic rhinitis (SAR) in adults and children 6 years of age and older. PATANASE® was found to have an onset of action of 30 minutes after dosing in the environmental exposure unit (Ref. USFDA approved label for Patanase).
Mometasone furoate is a glucocorticosteroid used topically to reduce inflammation of the skin or in the airways. Mometasone furoate monohydrate is commercially available in the United States as NASONEX®, a nasal spray indicated for (i) the treatment of nasal symptoms of allergic rhinitis in patients ≥2 years of age, (ii) the treatment of nasal congestion associated with seasonal allergic rhinitis in patients ≥2 years of age, (iii) the prophylaxis of seasonal allergic rhinitis in patients ≥12 years of age, and (iv) the treatment of nasal polyps in patients ≥18 years of age. It is available as 50 mcg in a metered-dose, manual pump spray unit containing an aqueous suspension of mometasone furoate monohydrate equivalent to 0.05% w/w mometasone furoate (calculated on the anhydrous basis).

Allergic rhinitis is an uncomfortable ailment and affects the quality of life of allergy sufferers. A fast onset of action would be highly desirable to provide quick relief from the symptoms of allergic rhinitis. There exists a need for therapies which provide a fast onset of action, preferably in less than 30 minutes.
The present invention relates to a fixed dose combination of mometasone or its salt and olopatadine or its salt and its use for the treatment of rhinitis in a subject in need thereof. The inventors have surprisingly found that mometasone furoate and olopatadine hydrochloride act synergistically in the treatment of allergic rhinitis and the combination is more effective and provides better therapeutic value than treatment with either active ingredient alone.
The inventors have also surprisingly found that nasal administration of a pharmaceutical composition of mometasone or a salt thereof (such as mometasone furoate) and olopatadine or a salt thereof (such as olopatadine hydrochloride) provides a faster onset of action of relief of symptoms associated with allergic rhinitis, such as seasonal allergic rhinitis or perennial allergic rhinitis, when compared to olopatadine hydrochloride monotherapy or mometasone fuorate monotherapy. In particular, the pharmaceutical composition provides faster relief of nasal symptoms, such as nasal congestion, rhinorrhea, itching and sneezing. The pharmaceutical composition may also provide a faster onset of action of ocular symptoms, such as ocular itching, tearing/watery eyes and ocular redness. The onset of action may be less than 30 minutes, such as within about 15 minutes, such as within about 10 minutes. In an embodiment, the present invention relates to a method of treating allergic rhinitis in a subject (e.g., a human) in need thereof comprising nasally administering to the subject an effective amount of a fixed-dose pharmaceutical composition comprising mometasone or its salt and olopatadine or its salt. Preferably, the composition is nasally administered as 1 or 2 sprays per nostril of the subject at least once daily.

In the context of present invention, the pharmaceutical composition when delivered as a nasal spray using a sprayer yields a specific spray pattern and spray droplet size. The spray pattern can be determined by various known techniques such as with an ADSA with NSPUA set up (Innova System) and the spray droplet size distribution can be determined by various known techniques such as with a Malvern Spraytec with NSPUA set up (Innova System).
The following describes a typical procedure for characterizing droplet size distribution of the spray—The sprayer is loaded with a composition as described above and primed by an actuating pump via an actuator until a fine mist appears out of the nozzle of the sprayer. A commercially available laser diffraction instrument is arranged so that the nozzle is about 3 cm or 6 cm below the laser beam of the laser diffraction instrument. The pump is actuated with a conventional mechanical actuator using a constant force. The resulting spray of the composition crosses the laser beam. Data are collected for D10, D50, D90, SPAN, and % Volume <10 μm. The average values for each of these parameters for three sprays are calculated.

The aqueous nasal spray suspension can be administered as a drop or any other form suitable for topical administration. The composition may also be administered using a nasal tampon or a nasal sponge.
In a preferred embodiment, the aqueous suspension is provided in the form of nasal spray wherein the suspension is administered in a single unit-dose container or multi-dose container. Suitable single unit-dose containers or multi-dose containers include, but are not limited to, glass, aluminum, polypropylene or high density polyethylene, for example, high density polyethylene containers produced using a blow-fill-seal manufacturing technique.
In one embodiment, the pharmaceutical composition is contained within a spray bottle (such as a sprayer). The spray bottle may include a container for storing the pharmaceutical composition and a pump for spraying the pharmaceutical composition intranasally. In one embodiment, the container is capable of storing 30, 56, 60, or 120, or 240 doses. For example, a container storing 240 doses can provide a 1 month supply of the pharmaceutical composition (2 sprays per nostril twice daily (8 sprays per day) for 30 days). A container storing 56 doses can provide a 1 week supply of the pharmaceutical composition (2 sprays per nostril twice daily (8 sprays per day) for 7 days). In one embodiment, the container may be suitable for containing 9-10 mL (e.g., 9 mL or 56 doses), 18-19 mL of the pharmaceutical composition (e.g., 18 mL or 120 doses), or 29-30 mL (e.g., 29 mL or 240 doses) of the pharmaceutical composition.

The following examples are provided to enable one skilled in the art to practice the invention and these are merely illustrative of the invention and should not be read as limiting the scope of the invention.
Male Dunkin Hartley guinea pigs were actively sensitized with a subcutaneous injection of 1.5 mg of ovalbumin and 20 mg of aluminum hydroxide gel on days 0 and 7. Guinea pigs were sensitized intranasally with 2% ovalbumin from days 14-17. On day 28, the animals were challenged with 6% ovalbumin intranasally.
Actively sensitized animals were randomly assigned to one of the following 5 groups during the experiment (see Table 1).
Mometasone furoate 10 μg was given intranasally 24 hours and 1 hour prior to the final ovalbumin challenge. Olopatadine hydrochloride was given intranasally 1 hour before the final ovalbumin challenge. The dosing volume was 40 μl/animal. The saline control group and ovalbumin control group received vehicle (40 μl, 0.1% Tween 80 in distilled water).
Sneezing response was determined by using whole body plethysmography (Buxco Research Systems, USA) for 50 minutes after final saline or ovalbumin challenge.
Nasal lavage was performed at 4 hours after challenge of animals with saline or ovalbumin on day 28. Animals were anesthetized with an overdose of urethane, the trachea was exposed and nasal lavage was performed using 2 mL pre-warmed normal saline. The collected nasal lavage was taken for total cell count using a hemocytometer. The nasal lavage was centrifuged, and the cell pellet resuspended in 15 μL guinea pig serum and used for preparation of smears. Slides were stained with Leishman's stain and a differential cell count of 100 cells based on standard morphology was performed manually.
The total number of eosinophils in each nasal lavage sample was calculated using the formula:
Percent inhibition of eosinophils was calculated using the following formula:
Data was statistically analyzed using one way ANOVA followed by Dunnett's multiple comparison tests.
Mometasone furoate monotherapy showed significant inhibition of total cell and eosinophils in nasal lavage but was not effective in inhibiting sneezing response. Olopatadine hydrochloride monotherapy did not show significant inhibition of any of the parameters in this model. The combination of mometasone furoate with olopatadine hydrochloride showed synergy for inhibition of sneezing response (
The combination of mometasone furoate and olopatadine hydrochloride showed a beneficial effect greater than the individual monotherapies. The combination of mometasone furoate and olopatadine hydrochloride showed synergy in the treatment of allergic rhinitis in this model.
The procedure in Example 1 was repeated except 120 μg of olopatadine hydrochloride (based on the equivalent weight of olopatadine free base) was used. The animal groups in Table 3 below were used during this experiment.
Compound administration was performed as in Example 1, except the dosing volume was 60 μl/animal. The saline control group and ovalbumin control group received vehicle (60 μl, 0.1% Tween 80 in distilled water). In vivo evaluations were performed as in Example 1.
Mometasone monotherapy showed significant inhibition of total cell and eosinophils in nasal lavage but was not effective in inhibiting sneezing response. Olopatadine monotherapy did not show significant inhibition of any of the parameter in this model. The combination of mometasone with olopatadine showed synergy for the inhibition of nasal eosinophilia, cellular infiltration in nasal lavage and sneezing response as compared to the respective monotherapies (see
The combination of mometasone furoate and olopatadine hydrochloride showed a beneficial effect greater than the individual monotherapies. The combination of mometasone and olopatadine showed synergy in this guinea pig rhinitis model.
The study was a single-centre, double blind, double-dummy, randomized, parallel-group, comparative Environmental Exposure Chamber (EEC) study to evaluate the efficacy, safety and tolerability of (i) two fixed dose combination products of mometasone furoate and olopatadine hydrochloride nasal spray, (ii) a fixed dose combination of azelastine hydrochloride and fluticasone propionate nasal spray (DYMISTA®), (iii) olopatadine nasal spray (PATANASE®), and (iv) a placebo nasal spray in patients with seasonal allergic rhinitis (SAR).
A total of 36 patients per treatment arm were randomized in the study. The total number of randomized subjects throughout the five treatment arms was 180.
Subjects suffering from seasonal allergic rhinitis for the last two years that require treatment either with intranasal antihistamines and/or intranasal steroids were included in the study.
Patients were randomized to treatment in a 1:1:1:1:1 ratio to the following five treatment arms, at one study site:
The double-dummy design including four masked nasal spray bottles (two for evening dosing and two for morning dosing) were utilized for this study (see Table A).
This study consisted of five visits to the study site and a 12 day at-home dosing period (and 2 days of onsite dosing—a total of 14 days of dosing). Assessment of efficacy endpoints were done out of season, in an EEC facility. After the initial screening visit (Visit 1), patients who met all study criteria (including the main criteria for inclusion: a positive skin prick test (SPT) and a 2 year medical history of allergic rhinitis (AR) to ragweed allergen) underwent further screening/priming in the EEC (Visit 2). During the EEC session patients were exposed to ragweed pollen at a concentration of 3500±500 particles/m3 for 6 hours. Patients used an electronic diary (ePDAT™) to rate their ocular and nasal symptoms every 30 minutes in the EEC Patients who met a minimum qualifying TNSS of 6/12, including a score of at least 2 for nasal congestion on two consecutive diary entries continued in the study. At Visit 3, on the following day (Day 1), patients who met the minimum criteria returned to the EEC for a second consecutive EEC session. Patients were exposed to allergen for approximately 10 hours during this visit. During the first 6 hours, patients used the electronic diary to complete symptom assessments every 30 minutes and met the minimum qualifying symptom score in order to continue. Those who met the minimum qualifying symptom score were randomized to receive one of the five study drugs after the 6 hours time point in the EEC. After dosing (at approximately noon), patients were asked to complete symptom assessments at 5 minute, 10 minutes, 15 minutes, 25 minutes, 30 minute, 45 minutes, 60 minutes and then every 30 minutes for the remainder of the visit Post-treatment symptom assessments in the EEC were used to determine onset of action for study treatments. Patients were then sent home with their study medication to continue at-home BID dosing starting from the evening dose for Day 1. Patients continued at-home dosing for a period of 12 days. Following the 12 days (Days 2-13) of at-home dosing, patients returned to the EEC on Day 14 (Visit 4) for a post-treatment 6-hour priming EEC session. Patients were dosed with the morning dose of study drug one hour prior to entering the EEC. Symptoms were assessed every 30 minutes in the EEC Patients took their last dose of study treatment at midnight on the same day, and returned on the following morning (Day 15, Visit 5) for a 6 hour EEC session Over a period of 6 hours, patients used the electronic diary to complete symptom assessments every 30 minutes. In addition to collection of nasal and ocular symptoms, the electronic diary was used to collect EEC-Quality-of-Life Questionnaires (EEC-QoLQ) at Visits 2, 3, 4 and 5, and acceptability and tolerability at Visit 5. Visit 5 was the final visit for the study.
Fulfillment of the following criteria on each of two consecutive diary cards reading at priming visit: minimum TNSS of 6 out of 12, including a score of at least 2 for nasal congestion.
The test product formulations used in the study were as follows:
Mometasone Furoate Monohydrate and Olopatadine Hydrochloride Nasal Spray (25 mcg+600 mcg)
Each spray delivered mometasone furoate monohydrate equivalent to 25 mcg mometasone furoate and olopatadine hydrochloride equivalent to 600 mcg olopatadine.
Mometasone Furoate Monohydrate and Olopatadine Hydrochloride Nasal Spray (50 mcg+600 mcg)
Each spray delivered mometasone furoate monohydrate equivalent to 50 mcg mometasone furoate and olopatadine hydrochloride equivalent to 600 mcg olopatadine.
Table B shows a summary of the TNSS change from baseline to post-treatment over 6 hours in EEC (ITT Population).
Table C shows a summary of the TNSS change from baseline to post-treatment over 12 hours in EEC (ITT Population). (The data for NASONEX in Table C is sourced from its U.S. FDA approved label.)
Table D shows a summary of the TOSS change from baseline to post-treatment over 12 hours in EEC (ITT Population).
The results of the study show that a combination of mometasone furoate and olopatadine hydrochloride, when administered nasally to a human patient, provides an effective treatment of seasonal allergic rhinitis and clinically significant reduction in both nasal and non-nasal symptoms associated therewith. The magnitude of this relief for TNSS was clinically relevant (i.e., greater than 2 units in difference—which is generally considered as clinically relevant—between the Test Products and Placebo). Test Product-1 showed overall better symptom relief as compared to the Reference Products (PATANASE® and DYMISTA®). Onset of action occurred by 10 minutes for TP-1 based on iTNSS change from baseline after the first dose at Visit 3 (−1.26). However, onset of action could not be defined for TP-2, DYMISTA, and PATANASE as statistically significant differences in iTNSS change from baseline between these treatments and placebo treatment were not observed at any 2 consecutive time points.
The study is a double-blind, randomized, parallel-group, comparative study to evaluate the efficacy, safety and tolerability of two different strengths and regimens of a fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray compared with a placebo nasal spray and individual monotherapy formulations of olopatadine hydrochloride nasal spray and mometasone furoate nasal spray, in subjects (12 years of age and older) with seasonal allergic rhinitis (SAR).
A total of 1,106 randomized subjects (158 subjects per treatment arm) were enrolled in the study.
Subjects were randomized to treatment in a 1:1:1:1:1:1:1 ratio to the following seven treatment arms, at multiple study sites.
The double-dummy design including two identical nasal spray bottles (one for morning [AM] dosing and one for evening [PM] dosing) are utilized for this study (Table F). The double-dummy design is ensured for adequate blinding considering that treatments being compared vary in dosing frequency (BID compared with QD).
This study consisted of four visits to the study site. After the initial screening visit (Visit 1), subjects who met all study selection criteria were required to undergo a single-blind placebo run-in period for 7-10 days. Following the completion of the run-in period, eligible subjects meeting the randomization criteria were enrolled and randomized to one of the seven treatment arms. Subjects were dispensed medication as per the randomization list. Randomized subjects were required to undergo a 2 week (14 days) treatment period as per the protocol to assess the efficacy and safety of the assigned treatment.
The non-nasal symptoms are assessed in a similar manner to the ocular symptoms above.
Table G shows a summary of the primary clinical endpoint (rTNSS) and secondary clinical endpoints (iTNSS, rTOSS, onset of action and RQLQ) observed during this Phase II study. For comparison of the combination therapy against a monotherapy, a p-value below 0.05 is considered statistically significant.
As can be seen from Table G, the combination of mometasone fuorate and olopatadine hydrochloride, when administered once daily (TP-2) or twice daily (TP-1) is statistically superior to placebo (p<0.0001) for the primary endpoint, change in rTNSS from baseline. The combination of mometasone fuorate and olopatadine hydrochloride, when administered once daily (TP-2) or twice daily (TP-1) also met secondary clinical endpoints in the trial, supportive of its efficacy in the treatment of seasonal allergic rhinitis (SAR). The combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1) was also statistically superior to the individual monotherapies (GO-2 and GM-2) for both primary (rTNSS) and secondary endpoints (iTNSS).
Table G2 shows the least squares mean difference in individual reflective nasal symptoms scores for TP-1 and TP-2 versus placebo.
Table H shows a summary of the treatment emergent adverse events (TEAEs) observed during this Phase II study.
All TEAEs were mild to moderate. Dysgeusia (1.3%) and headache (1.9%) were adverse events (AEs) reported for the combination of mometasone fuorate and olopatadine hydrochloride administered twice daily (BID) and once daily (QD), respectively.
This study was a double-blind, randomized, parallel-group, comparative study to evaluate the efficacy, safety and tolerability of a fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray compared with a placebo nasal spray and individual monotherapy formulations of olopatadine hydrochloride nasal spray and mometasone furoate nasal spray, in subjects (12 years of age and older) with seasonal allergic rhinitis (SAR), spring season.
A total of 1,180 randomized subjects (295 subjects per treatment arm) were enrolled in the study.
Key Subject Selection Criteria:
Subjects were randomized to treatment in a 1:1:1:1 ratio to the following four treatment arms, at multiple study sites.
This study consisted of four visits to the study site. After the initial screening visit (Visit 1), subjects who met all study selection criteria were required to undergo a single-blind placebo run-in period for 7-10 days. Following the completion of the run-in period, eligible subjects meeting the randomization criteria were enrolled and randomized to one of the four treatment arms. Subjects were dispensed medication as per the randomization list. Randomized subjects were required to undergo a 2 week (14 days) treatment period as per the protocol to assess the efficacy and safety of the assigned treatment. Subjects were instructed to record the symptom scores in a symptom assessment diary. They were also scheduled to have at least two blood samples for PK assessment during the treatment period.
The non-nasal symptoms are assessed in a similar manner to the ocular symptoms above.
Physician assessed Nasal Symptom Score (PNSS), Rhinoconjuntivitis Quality of Life Questionnaire Standardized Activities (RQLQ(S)), and Rhinitis Control Assessment Test (RCAT):
Table K shows a summary of the primary clinical endpoint (rTNSS) and secondary clinical endpoints (iTNSS, rTOSS, onset of action and RQLQ) observed during this Phase III study. For comparison of the combination therapy against a monotherapy, a p-value below 0.05 is considered statistically significant.
As can be seen from Table K, the combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1) is statistically superior to placebo (p<0.0001) for the primary endpoint, change in rTNSS from baseline, and is statistically superior to olopatadine hydrochloride monotherapy (GO-2). The secondary endpoints were also statistically significant for combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1), supportive of its efficacy in the treatment of seasonal allergic rhinitis (SAR).
The combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1) also exhibited a faster (rapid) onset of action (an onset of action within 15 minutes), as measured by iTNSS, when compared to olopatadine hydrochloride monotherapy or mometasone fuorate monotherapy.
All TEAEs were mild to moderate. Dysgeusia (3.3%) and headache (0.7%) reported as adverse events for the combination of mometasone fuorate and olopatadine hydrochloride administered twice daily (BID).
The pharmacokinetics (PK) of TP-1 were measured for a subset of patients in the phase III clinical study on day 1 and day 8 (steady state). The PK results for patients receiving TP-1 are provided below.
This study was a double-blind, randomized, parallel-group, comparative study to evaluate the efficacy, safety and tolerability of a fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray compared with a placebo nasal spray and individual monotherapy formulations of olopatadine hydrochloride nasal spray and mometasone furoate nasal spray, in subjects (12 years of age and older) with seasonal allergic rhinitis (SAR), fall and mountain cedar season.

Table N shows a summary of the primary clinical endpoint (rTNSS) and secondary clinical endpoints (iTNSS, rTOSS, onset of action and RQLQ) observed during this Phase III study. For comparison of the combination therapy against a monotherapy, a p-value below 0.05 is considered statistically significant.
As can be seen from Table N, the combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1) is statistically superior to placebo (p<0.0001) for the primary endpoint, change in rTNSS from baseline, and is statistically superior to olopatadine hydrochloride monotherapy (GO-2) and mometasone fuorate monotherapy (GM-2). The secondary endpoints were also statistically significant for combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1), supportive of its efficacy in the treatment of seasonal allergic rhinitis (SAR).
Table N2 shows the least squares mean difference in individual reflective and instantaneous nasal symptoms scores for the TP-1 group versus the placebo group.
The combination of mometasone fuorate and olopatadine hydrochloride, when administered twice daily (TP-1) also exhibited a faster (rapid) onset of action (an onset of action within 15 minutes), as measured by iTNSS, when compared to olopatadine hydrochloride monotherapy or mometasone fuorate monotherapy.
All TEAEs were mild to moderate. Dysgeusia (3.8%) nasal discomfort (1%) and urinary tract infection (1%) were reported adverse events for the combination of mometasone fuorate and olopatadine hydrochloride administered twice daily (BID).
The study is a double-blind, randomized, parallel-group, comparative study to evaluate the long-term safety, efficacy, and tolerability of a fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray compared with two placebo nasal sprays, in subjects (12 years of age and older) with perennial allergic rhinitis (PAR).
To compare the long-term safety and tolerability of mometasone furoate and olopatadine hydrochloride nasal spray twice daily with two placebo nasal sprays at the same dose in the same vehicle over 52 weeks of study treatment in subjects with PAR.
A secondary objective is to evaluate the long-term efficacy of a fixed dose combination of mometasone furoate and olopatadine hydrochloride nasal spray compared with a placebo nasal spray formulations (pH=3.7) in subjects with PAR.
A total of 601 randomized subjects were enrolled in the study. Subjects were randomized to treatment in a 4:1:1 ratio to 3 treatment groups, at multiple site. The treatment groups are provided in Table I below.
This study consisted of twelve visits to the study site. After the initial screening visit (Visit 1), subjects who met all study selection criteria underwent a single-blind placebo run-in period for 7-10 days. Following the completion of the run-in period, eligible subjects meeting the randomization criteria were enrolled and randomized to one of the three treatment arms. Randomized subjects underwent a 52 week treatment period as per the protocol to assess the efficacy and safety of the assigned treatment.
Primary Endpoints
Secondary Endpoints
Efficacy Endpoints
Other Efficacy Endpoints
Other endpoints included other assessments of AM subject-reported individual nasal symptoms, AM subject-reported rTNSS and iTNSS from baseline to the end of each treatment week, Physician-assessed Nasal Symptom Score and physician-assessed individual nasal symptoms, individual domains of the RQLQ for the FAS population, and change from baseline in the Rhinitis Control Assessment Test and individual domains of Rhinitis Control Assessment Test.
Efficacy analysis was conducted on the FAS and PPS.
Change from baseline in average AM rTNSS and iTNSS over the first 6, 30, and 52 weeks of treatment was analyzed using an analysis of covariance (ANCOVA) model adjusting for study treatment group, site, and baseline (defined as the average of the last 4 consecutive AM assessments during the last 4 days of the run-in period from the Day −3 AM assessment to the AM assessment on the day of randomization). Least squares means (LSMs) of the treatment differences and associated 95% confidence intervals (95% CIs) and p-values were presented.
Changes from baseline in rTNSS and iTNSS at the end of each week of treatment and changes from baseline in individual nasal symptom scores over the first 6, 30, and 52 weeks (and at the end of each treatment week) of the treatment period were analyzed in a similar manner as described above.
Changes from baseline in RQLQ(S) at Weeks 6, 30, and 52 were analyzed for the FAS and the RQLQ(S) Analysis Set using ANCOVA models adjusting for study treatment group, site, and baseline RQLQ(S) (linear, continuous covariate). At each time-point, only completers of the respective visit were analyzed.
The analyses of RCAT results were similar to the RQLQ(S) analyses except that it was performed only for the FAS.
Adverse events occurring after the first dose of randomized study medication were defined as TEAEs.
The safety endpoints related to AEs were:
The table below summarizes the safety analysis for the three treatment groups over the 52 week administration period.
As can be seen, there was no meaningful differences between the three treatment groups. The majority of TEALs were mild to moderate severity and considered “not related” by the investigator. The TP-1 treatment was safe and well tolerated, with safety profiles consistent with those expected for the individual monotherapy components. No deaths were reported during the study.
The table below summarizes the results for the efficacy endpoint: nasal symptoms average AMV Reflective Total Nasal Symptoms (rTNSS, last 12 hours) (full set analysis, FAS).
