The present disclosure relates generally to compositions and kits comprising an RNA interference (RNAi) component and a capsid assembly modulator and their uses for treating Hepatitis B Virus infection or inhibiting the expression of at least one Hepatitis B Virus gene.
The Hepatitis B Virus (HBV) is a strict hepatotrophic, double-stranded DNA containing virus. Although DNA is the genetic material, the replication cycle involves a reverse transcription step to copy a pregenomic RNA into DNA. Hepatitis B Virus is classified as one member of the Hepadnaviruses and belongs to the family of Hepadnaviridae. The primary infection of adult humans with Hepatitis B Virus causes an acute hepatitis with symptoms of organ inflammation, fever, jaundice and increased liver transaminases in blood. Those patients that are not able to overcome the virus infection suffer a chronic disease progression over many years with increased risk of developing cirrhotic liver or liver cancer. Perinatal transmission from Hepatitis B Virus-infected mothers to newborns also leads to chronic hepatitis.
Upon uptake by hepatocytes, the nucleocapsid is transferred to the nucleus and DNA is released. There, the DNA strand synthesis is completed and gaps repaired to give the covalently closed circular (ccc) supercoiled DNA of 3.2 kb. The cccDNA serves as a template for transcription of five major viral mRNAs, which are 3.5, 3.5, 2.4, 2.1 and 0.7 kb long. All mRNAs are 5′-capped and polyadenylated at the 3′-end. There is sequence overlap at the 3′-end between all five mRNAs
One 3.5 kb mRNA serves as template for core protein and polymerase production. In addition, the same transcript serves as a pre-genomic replication intermediate and allows the viral polymerase to initiate the reverse transcription into DNA. Core protein is needed for nucleocapsid formation. The other 3.5 kb mRNA encodes pre-core, the secretable e-antigen (HBeAg). In the absence of replication inhibitors, the abundance of e-antigen in blood correlates with Hepatitis B Virus replication in liver and serves as an important diagnostic marker for monitoring the disease progression.
The 2.4 and 2.1 kb mRNAs carry the open reading frames (“ORF”) pre-S1, pre-S2 and S for expression of viral large, medium and small surface antigen. The s-antigen is associated with infectious, complete particles. In addition, blood of infected patients also contain non-infectious particles derived from s-antigen alone, free of genomic DNA or polymerase. The function of these particles is not fully understood. The complete and lasting depletion of detectable s-antigen in blood is considered as a reliable indicator for Hepatitis B Virus clearance.
The 0.7 kb mRNA encodes the X protein. This gene product is important for efficient transcription of viral genes and also acts as a transactivator on host gene expression. The latter activity seems to be important for hepatocyte transformation during development of liver cancer.
Patients with detectable s-antigen, e-antigen, and/or viral DNA in the blood for more than 6 months are considered chronically infected. Nucleoside analogs as inhibitors of reverse transcriptase activity are typically the first treatment option for many patients. Administration of lamivudine, tenofovir, and/or entecavir has been shown to suppress Hepatitis B Virus replication, sometimes to undetectable levels, with improvement of liver function and reduction of liver inflammation typically seen as the most important benefits. However, only few patients achieve complete and lasting remission after the end of treatment. Furthermore, the Hepatitis B Virus develops drug resistance with increasing duration of treatment. This is especially difficult for patients co-infected with Hepatitis B and Human Immunodeficiency Virus (HIV). Both viruses are susceptible to nucleoside analogue drugs and may co-develop resistance.
A second treatment option is the administration of interferon-alpha. Here, patients receive high doses of interferon-alpha over a period of 6 months. The Asian genotype B gives very poor response rates. Co-infection with Hepatitis D Virus (HDV) or Human Immunodeficiency Virus has been shown to render interferon-alpha therapy completely ineffective. Patients with strong liver damage and heavy fibrotic conditions are not qualified for interferon-alpha therapy.
Certain Hepatitis B Virus-specific RNA interference (RNAi) agents have been previously shown to inhibit expression of HBV gene expression. For example, U.S. Patent Application Publication No. 2013/0005793, to Chin et al., which is incorporated herein by reference in its entirety, discloses certain double-stranded ribonucleic acid (dsRNA) molecules for inhibiting the expression of Hepatitis B Virus gene.
Additionally, HBV inhibitors, such as capsid assembly modulator (CAM), can bind to Hepatitis B core protein and interferes with the viral capsid assembly process, thereby preventing the polymerase-bound pgRNA encapsidation. This results in the formation of HBV capsids, devoid of HBV DNA or RNA (non-functional capsids), and ultimately in the inhibition of HBV replication. See e.g., WO2014184350A1. The reference WO2014184350A1 is incorporated herein in its entirety, particularly the descriptions of the capsid assembly modulator compounds and the method of preparing them.
There is a need for improved HBV therapy that can overcome at least one of the disadvantages of existing treatment options, such as are toxicity, mutagenicity, lack of selectivity, poor efficacy, poor bioavailability, and difficulty of synthesis, while providing additional benefits such as increased potency or an increased safety window.

The pharmaceutical compositions including an HBV RNAi agent described herein can be delivered to a cell, group of cells, tumor, tissue, or subject using oligonucleotide delivery technologies known in the art. In general, any suitable method recognized in the art for delivering a nucleic acid molecule (in vitro or in vivo) can be adapted for use with a herein described compositions. For example, delivery can be by local administration, (e.g., direct injection, implantation, or topical administering), systemic administration, or subcutaneous, intravenous, intraperitoneal, or parenteral routes, including intracranial (e.g., intraventricular, intraparenchymal and intrathecal), intramuscular, transdermal, airway (aerosol), nasal, oral, rectal, or topical (including buccal and sublingual) administration. In certain embodiments, the compositions are administered by subcutaneous or intravenous infusion or injection.
Accordingly, in some embodiments, the herein described pharmaceutical compositions may comprise one or more pharmaceutically acceptable excipients. In some embodiments, the pharmaceutical compositions described herein can be formulated for administration to a subject.
As used herein, a pharmaceutical composition or medicament includes a pharmacologically effective amount of at least one of the described therapeutic compounds and one or more pharmaceutically acceptable excipients. Pharmaceutically acceptable excipients (excipients) are substances other than the Active Pharmaceutical ingredient (API, therapeutic product, e.g., HBV RNAi agent) that are intentionally included in the drug delivery system. Excipients do not exert or are not intended to exert a therapeutic effect at the intended dosage. Excipients may act to a) aid in processing of the drug delivery system during manufacture, b) protect, support or enhance stability, bioavailability or patient acceptability of the API, c) assist in product identification, and/or d) enhance any other attribute of the overall safety, effectiveness, of delivery of the API during storage or use. A pharmaceutically acceptable excipient may or may not be an inert substance.
Excipients include, but are not limited to: absorption enhancers, anti-adherents, anti-foaming agents, anti-oxidants, binders, buffering agents, carriers, coating agents, colors, delivery enhancers, delivery polymers, dextran, dextrose, diluents, disintegrants, emulsifiers, extenders, fillers, flavors, glidants, humectants, lubricants, oils, polymers, preservatives, saline, salts, solvents, sugars, suspending agents, sustained release matrices, sweeteners, thickening agents, tonicity agents, vehicles, water-repelling agents, and wetting agents.

For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor ELTM (BASF, Parsippany, N.J.) or phosphate buffered saline. It should be stable under the conditions of manufacture and storage and should be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyethylene glycol), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as mannitol, sorbitol, and sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin.
Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filter sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation include vacuum drying and freeze-drying which yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof.
Formulations suitable for intra-articular administration can be in the form of a sterile aqueous preparation of the drug that can be in microcrystalline form, for example, in the form of an aqueous microcrystalline suspension. Liposomal formulations or biodegradable polymer systems can also be used to present the drug for both intra-articular and ophthalmic administration.
The active compounds can be prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid.

A multi-site, Phase I/2a human clinical trial assessing the safety, tolerability, pharmacokinetic, and pharmacodynamic effects of a combination comprising an RNAi component and a capsid assembly modulator in Normal Adult Volunteers was conducted. The study was designed to evaluate, amongst other outcomes, the safety and pharmacological effects of the combination therapy in patients with chronic hepatitis B (CHB). The combination comprised Compound A and an RNAi component comprising of a first RNAi agent comprising SEQ ID NO: 2 and SEQ ID NO: 11 and an effective amount of a second RNAi agent comprising SEQ ID NO: 16 and SEQ ID NO: 8 in a ratio of 2:1. The study subject population included adult males and females, aged 18-55, with or without CHB.
Subjects were given (1) 25-400 mg of the RNAi component as a subcutaneous injection in a single dose or in multiple doses at specific time intervals (depending on the patient cohort) and, in one cohort, subjects were also given (2) 250 mg of compound A as oral tablets (25 mg and 100 mg) daily (from Day 1 to Day 84, inclusive). All patients in all HBV cohorts received NA from day 1 (either TDF or ETV at the approved doses (245 mg for TDF or 0.5 mg for ETV)). Safety assessments included: vital sign assessment (resting heart rate, blood pressure, respiratory rate, temperature); clinical laboratory measurements (biochemistry, hematology, coagulation, urinalysis); resting ECG measurements; assessment of changes in patients' other concurrent medication/therapy; assessment of injection sites; and a 90-day post-EOS pregnancy follow-up call. Efficacy evaluation was made based on a combination of safety/tolerability data (occurrence of adverse events, blood sample analysis); pharmacokinetic data (RNAi component/NUC (nucleos(t)ide inhibitors)/compound A plasma concentrations); and pharmacodynamic data (immunology and virology assessments). The study parameters are summarized in Table 4.
HBsAg changes for individual participants (cohort 12) receiving (1) 200 mg RNAi component, (2) 250 mg compound A daily and (3) NA and the mean HBsAg decline from base line after a single subcutaneous dose of the RNAi component are shown in
Also reported here is a cohort exploring the triple combination therapy of the RNAi component, compound A and an NA (i.e., cohort 12). Efficacy and safety data up to Day 113 (i.e., two months post RNAi component dosing, and one month post compound A dosing). In cohort 12, CHB patients who were HBeAg positive or negative, NA-experienced (regardless of HBV DNA level) or NA-naïve were enrolled and received the following triple combination treatment: (1) three 200 mg RNAi component subcutaneous doses (i.e. on Days 1, 29 and 57); (2) oral compound A 250 mg once daily for 12 weeks (i.e. until Day 85); and (3) all patients either started or continued with NA (ETV or TDF) treatment on Day 1, which continued beyond the end of compound A dosing. Study visits were at screening and on Days 1, 8, 15, 29, 43, 57, 85 and 113, then extended follow up approximately every 2 months for 12 months. Serum viral parameters were assessed, i.e., HBV DNA (lower limit of quantification [LLOQ]: 20 IU/mL), HBV RNA (LLOQ: 1.65 log10 U/mL4), HBsAg (LLOQ: 0.05 IU/mL), HBeAg (LLOQ: 0.01 PEIU/mL; value below 0.11 PEIU/mL are reported as not detected), and HBcrAg (LLOQ: 1 kU/mL). Safety assessments included clinical laboratory assessments and adverse events (AEs) assessed from screening through Day 113, as reported here, and through the extended follow-up period.
Baseline characteristics and demographics information for cohort 12 is shown in Table 5. All patients received their planned RNAi component, compound A and NA doses with no treatment discontinuations or dose adjustments.
HBsAg changes for individual participants (cohort 12) receiving (1) 200 mg RNAi component, (2) 250 mg compound A daily and (3) NA and the mean HBsAg decline from base line after three subcutaneous doses of the RNAi component on Day 1, 29 and 57 are shown in
HBsAg changes for individual participants (cohort 12) receiving (1) 200 mg RNAi component, (2) 250 mg compound A daily and (3) NA on Day 113 from base line after three subcutaneous doses of the RNAi component on Day 1, 29 and 57 are shown in
HBV DNA, HBV RNA, HBeAg and HBcrAg changes for individual participants (cohort 12) receiving (1) 200 mg RNAi component, (2) 250 mg compound A daily and (3) NA from base line after three subcutaneous doses of the RNAi component on Day 1, 29 and 57 are shown in
Three doses of 200 mg Q4w RNAi component in combination with daily 250 mg compound A for 12 weeks and an NA daily were generally well tolerated in CHB patients as of the safety data cutoff. No deaths, discontinuations, serious adverse events or sever adverse events were reported. Two AEs of mild respiratory infection, not related to treatment, were reported. There were no clinically significant findings on vital signs, 12-lead electrocardiograms, hematology or clinical chemistry parameters. The only notable treatment-emergent laboratory findings were grade 1, transient isolated alanine aminotransferase elevations (n=5 patients, 57-122 U/L), which resolved with continued dosing and were potentially induced by reduction of viral parameters.
This triple combination was well tolerated, and all CHB patients achieved robust reductions in HBsAg, HBV DNA, and HBV RNA. Reductions in HBeAg and HBcrAg were generally less pronounced during the dosing period. All patients achieved a ≥1.0 log10 IU/mL (90%) reduction (nadir ranged from −1.01 to −2.26 log10 IU/mL) in HBsAg. HBsAg reductions were similar in HBeAg positive and HBeAg negative patients. Studies of longer duration with this triple combination are underway aimed at assessing functional cure rates in patients with CHB.
Also reported here are efficacy and safety data collected in cohorts 1b, 1c and 2b-5b. In cohorts 1b, 1c and 2b-5b, HBeAg positive or negative, NA-experienced or -naïve CHB patients were enrolled and received three subcutaneous RNAi component doses of 25, 50, 100, 200, 300 or 400 mg Q4w on Days 1, 27 and 57. All patients either started (NA-naïve) or continued (NA-experienced) with daily NA (TDF or ETV) treatment on Day 1 and continued beyond the end of RNAi component dosing. Study visits were at screening and on Days 1, 8, 15, 29, 43, 57, 85 and 113, then extended follow up approximately every 2 months for 12 months. Serum viral parameters were assessed, i.e., HBV DNA (lower limit of quantification [LLOQ]: 20 IU/mL), HBV RNA (LLOQ: 1.65 log10 U/mL4), HBsAg (LLOQ: 0.05 IU/mL), HBeAg (LLOQ: 0.01 PEIU/mL; value below 0.11 PEIU/mL are reported as not detected), and HBcrAg (LLOQ: 1 kU/mL). Safety assessments included clinical laboratory assessments and adverse events (AEs) assessed from screening through Day 113, as reported here, and through the extended follow-up period.
Baseline characteristics and demographics information for cohorts 1b, 1c, 2b, 3b, 4b and 5b is shown in Table 6. Most patients were NA-experienced (40/48, 83%). All patients received their planned RNAi component doses with no treatment discontinuations.

HBV DNA, HBV RNA, HBeAg and HBcrAg changes for individual participants (cohorts 1b, 1c, 2b, 3b, 4b and 5b) receiving 25 mg (cohort 1b), 50 mg (cohort 1c), 100 mg (cohort 2b), 200 mg (cohort 3b), 300 mg (cohort 4b) or 400 mg (cohort 5b) on Day 1, 29 and 57 are shown in
Adverse events (AE) possibly or probably drug related occurring up to and including Day 113 of treatment for participants in cohorts 1b, 1c, 2b, 3b, 4b and 5b are shown in Table 7 below. Safety data for Cohorts 1b to 5b through Day 113 showed that three monthly doses of RNAi component at 25-400 mg with an NA were generally well tolerated in CHB patients. Three non-drug related serious adverse events were reported (anxiety with depression in a single patient and menorrhagia, each requiring hospitalization). The most commonly reported AEs at least possibly drug related consisted of various AEs at the injection site (e.g, discoloration, erythema, bruising, rash), which were all mild and reported in five patients. There were no reports of thrombocytopenia and one report of possibly drug-related Stage 1 acute kidney injury with creatinine increase (from 1.10 mg/dL Day 1 pre-dose to a peak of 1.55 mg/dL on Day 8 and return to 1.06 mg/dL on Day 15), which was treatment emergent but likely due to creatine supplementation and did not lead to treatment interruption or adjustment. A single AE reported of mild, possibly related, abnormal liver function tests (peak alanine aminotransferase [ALT] 136 U/L) was reported, representing the highest treatment-emergent ALT elevation in cohorts 1b to 5b through Day 113 (end of study). There were no cases of simultaneous elevations of ALT >3× upper limit of normal and total bilirubin >2× upper limit of normal.
a MedDRA preferred term aggregated based on similarity
In CHB patients, RNAi component with an NA had strong activity against HBsAg, HBV DNA and HBV RNA. Reductions in HBeAg and HBcrAg were generally less pronounced. HBsAg reductions were similar in HBeAg positive and HBeAg negative patients. Expanded cohorts with 100-400 mg RNAi component confirmed previous findings that HBsAg declines were similar with these doses; 97% (31/32) of these patients achieved a ≥1.0 log10 (90%) reduction in HBsAg. The 25 mg and 50 mg RNAi component doses were active in reducing HBsAg, and appeared less effective than higher doses. HBsAg responses with RNAi component are consistent with its ability to silence HBV RNA from cccDNA and host-integrated viral DNA (which is a major source of HBsAg in certain CHB populations). RNAi component (and NA) treatment was well tolerated at doses up to 400 mg Q4w for three doses. Overall, RNAi component demonstrated anti-HBV characteristics desirable for an RNAi therapy. Studies of longer duration are underway, including triple combinations aimed at functional cure in CHB patients.
A Phase 2b, multicenter, double-blind, active-controlled, dose-finding, randomized study to investigate the efficacy and safety of different combination regimens, including an RNAi component and/or a capsid assembly modulator, for the treatment of chronic hepatitis B (CHB) virus infection is conducted. The study subject population includes adult males and females, aged 18-65, with CHB. The combination comprises Compound A and an RNAi component comprising an effective amount of a first RNAi agent comprising SEQ ID NO: 2 and SEQ ID NO: 11 and an effective amount of a second RNAi agent comprising SEQ ID NO: 16 and SEQ ID NO: 8 in a ratio of 2:1.
Subjects are given a combination of (1) 40 mg, 100 mg or 200 mg once monthly of the RNAi component by subcutaneous injection, or a corresponding placebo; and (2) 250 mg once daily of Compound A as oral tablets (25 mg and 100 mg), or a corresponding placebo; and (3) NA (ETV: nucleoside-naïve patients=0.5 mg daily; lamivudine-refractory patients=1 mg once daily; TDF=300 mg once daily; TAF: 25 mg once daily) as oral tablets (ETV 0.5 mg; TDF 300 mg; TAF 25 mg). The active treatment phase lasts up to 48 weeks in total following a 4-week screening phase. The primary hypothesis of this study is that one or more combination regimens are more efficacious than NA treatment alone, as measured by the primary efficacy endpoint, the proportion of participants with HBsAg seroclearance 24 weeks after completion of all study intervention at Week 48. After 48 weeks, participants who meet the NA treatment completion criteria complete treatment with the RNAi component, compound A and NA, and are monitored closely during a follow-up phase. Participants who do not meet the NA treatment completion criteria continue to receive NA treatment during the 48-week follow up period which could be extended to a maximum duration of 96 weeks. Safety and efficacy evaluation criteria, as well as the study parameters, are summarized in Table 8.
