AbbVie's VIEKIRAX® (ombitasvir/paritaprevir/ritonavir tablets) Receives Approval in Japan for the Treatment of Genotype 1 Chronic Hepatitis C

• New interferon and ribavirin-free treatment option for patients with most common type of hepatitis in Japan, genotype 1 chronic hepatitis C, including those with compensated cirrhosis[1]
• VIEKIRAX consists of a 12-week, two direct-acting antiviral, fixed-dose combination of paritaprevir/ritonavir with ombitasvir, dosed once daily[1]
• Approximately 1.5 to 2 million people are living with hepatitis C in Japan, one of the highest rates of hepatitis C infection in the industrialized world[2],[3]

NORTH CHICAGO, Ill., Sept. 28, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced that the Japanese Ministry of Health, Labour and Welfare (MHLW) approved VIEKIRAX® (ombitasvir/paritaprevir/ritonavir), as a new interferon and ribavirin-free treatment option for adult patients with chronic genotype 1 (GT1) hepatitis C virus (HCV) infection, including those with compensated liver cirrhosis.1 VIEKIRAX consists of a 12-week, two direct-acting antiviral, fixed-dose combination of paritaprevir/ritonavir with ombitasvir, dosed once daily.

"Today's approval represents an important step forward for the treatment of Japanese patients, a population with specific needs based on patient and viral characteristics," said Jean-Michel Pawlotsky, MD, PhD, professor of medicine at the University of Paris-Est, France. "VIEKIRAX is a valuable new addition to a number of treatments that are changing the face of hepatitis C, making it possible to achieve high virologic cure rates, even in patients whose disease has progressed to compensated liver cirrhosis."

Japan has one of the highest rates of hepatitis C infection in the industrialized world, with approximately 1.5 to 2 million people living with HCV.2, 3 Genotype 1 is the most common HCV genotype in Japan with 60 to 70 percent of patients infected and, of those, about 95 percent are infected with the genotype 1b (GT1b) sub-type.4

"We are pleased to provide VIEKIRAX as a new treatment that offers a high probability of virologic cure for GT1b HCV patients and are working to support access to our treatment in Japan," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "We are also prioritizing disease education and awareness by collaborating with stakeholders to identify and address the diverse challenges across Japan, such as supporting screening and diagnosis initiatives, and providing accurate information to the medical community about treatment options."

The approval is supported by the Phase 3 GIFT-I study.1 An overall 95 percent (n=140/148) of treatment-naïve and 94 percent (n=102/109) of treatment-experienced GT1b HCV infected patients achieved SVR12 with VIEKIRAX.1

The primary endpoint was achieved, demonstrating 95 percent (n=106/112) SVR12 in a sub-group of treatment-naïve, non-cirrhotic, adult GT1b HCV infected Japanese patients who were eligible for therapy with interferon (IFN) and had a high viral load. A secondary endpoint in GT1b HCV patients with compensated cirrhosis achieved 91 percent (n=38/42) SVR12.5

Across all treatment arms three patients (n=3/363) experienced on-treatment virologic failure, eight patients (n=8/354) experienced post-treatment relapse and three patients discontinued treatment due to adverse events. The most commonly reported adverse events (>5 percent in any arm) were nasopharyngitis, headache, peripheral edema, nausea, pyrexia and decreased platelet count.5 In April 2015, AbbVie was granted priority review by the MHLW for VIEKIRAX, on the basis of clinical usefulness of the treatment and recognizing the severity and unmet need of the disease in Japan.

About the GIFT-I Study5

GIFT-I comprises 363 patients in two sub-studies.

In sub-study 1, 321 genotype 1b (GT1b) patients without cirrhosis, both treatment-naïve and interferon (IFN) [with or without ribavirin (RBV)] treatment-experienced, were randomized to receive either ombitasvir/paritaprevir/ritonavir (Arm A) [OBV/PTV/r] or placebo (Arm B) [2:1 randomization ratio, stratified by treatment history, past response, viral load and IFN eligibility]. Patients initially randomized to placebo (Arm B) then received OBV/PTV/r for an additional 12 weeks of open-label treatment. Sustained virologic response was assessed 12 weeks post-treatment (SVR12) as a primary efficacy endpoint in a sub-group of previously untreated, non-cirrhotic GT1b patients who were eligible for therapy with IFN and had a high viral load, defined as an HCV RNA level ≥ 100,000 IU/mL and received at least one dose of the double-blind, active study drug.

In sub-study 2, 42 GT1b treatment-naïve and IFN (with or without RBV) treatment-experienced patients with compensated cirrhosis received open-label treatment for 12 weeks (Arm C) with SVR12 and assessed as a secondary efficacy endpoint.

One patient from each arm (n=3/363) experienced on-treatment virologic failure [Arm A, 0.5% (n=1/215); Arm B, 0.9% (n=1/106); Arm C, 2.4% (n=1/42)]. Across all arms, eight patients (n=8/354) experienced post-treatment relapse [Arm A, 2.4% (n=5/209); Arm B, 1.0% (n=1/105); Arm C, 5.0% (n=2/40)].

AbbVie studied its two direct-acting antiviral treatment regimen without RBV in Japan due to patient and viral characteristics specific to the Japanese population, including high prevalence of GT1b.

About VIEKIRAX in Japan

Indication in Japan

VIEKIRAX is indicated for the improvement of viremia in chronic hepatitis C or compensated hepatic cirrhosis C in patients of serogroup 1 (genotype 1).

Summary of Safety Information

Contraindications

VIEKIRAX is contraindicated in patients with a history of known hypersensitivity to an ingredient in VIEKIRAX, patients with severe hepatic impairment (Child-Pugh C) or patients being treated with the following drugs: azelnidipine, triazolam, iv midazolam, blonanserin, pimozide, ergotamine tartrate, dihydroergotamine mesilate, ergometrine maleate, methylergometrine maleate, sildenafil citrate [Revatio], tadalafil [Adcirca], rivaroxaban, vardenafil hydrochloride hydrate, riociguat, simvastatin, atorvastatin calcium hydrate, carbamazepine, phenytoin, phenobarbital, rifampin, efavirenz, foods containing St. John's Wort (Hypericum perforatum), ethinyl estradiol-containing medicinal products.

Precautions for Use

Positive result for HCV RNA should be confirmed before administering VIEKIRAX and decompensated cirrhosis should be excluded.

When VIEKIRAX is used for patients co-infected with HIV/HCV, administer VIEKIRAX only to patients whose virological suppression has been achieved by anti-HIV therapy as ritonavir may cause resistance against a HIV protease inhibitor.

During the administration of VIEKIRAX, perform liver function tests regularly because hepatic function disorder may occur.

Co-administration of VIEKIRAX with drugs that are substrates of CYP3A4, P-gp, BCRP, OATP1B1 or OATP1B3 may result in increased plasma concentrations of such drugs, potentially requiring dose adjustment or clinical monitoring.

The safety of VIEKIRAX in pregnant women has not been established. VIEKIRAX should be used in pregnant women and women who may possibly be pregnant only if the expected therapeutic benefits outweigh the possible risks associated with treatment.

Do not administer VIEKIRAX to nursing mothers. If VIEKIRAX is administered to a nursing mother by necessity, breast feeding must be discontinued during treatment.

Safety and effectiveness have not been established in children.

Adverse Reactions

Major adverse reactions included peripheral edema in 15 subjects (4.1%), headache in 12 subjects (3.3%) and nausea in 10 subjects (2.8%)

Japan’s Ministry of Health, Labour and Welfare Approves Gilead’s Harvoni®, the First Once-Daily Single Tablet Regimen for the Treatment of Genotype 1 Chronic Hepatitis C

– Harvoni Achieved Cure Rates (SVR12) of 100 Percent in Japanese Phase 3 Study –

– Eliminates Need for Interferon and Ribavirin for Patients with Genotype 1 Hepatitis C –

 

July 03, 2015 02:00 AM Eastern Daylight Time

FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (NASDAQ:GILD) today announced that the Japanese Ministry of Health, Labour and Welfare (MHLW) has approved Harvoni^® (ledipasvir 90 mg/sofosbuvir 400 mg), the first once-daily single tablet regimen for the treatment of chronic hepatitis C genotype 1 infection in adults. Harvoni combines the NS5A inhibitor ledipasvir with the nucleotide analog polymerase inhibitor sofosbuvir, approved by the MHLW under the trade name Sovaldi^® in March 2015. Harvoni is indicated for the suppression of viremia in patients with genotype 1 chronic hepatitis C virus (HCV) infection with or without compensated cirrhosis, with a treatment duration of 12 weeks.

“Today’s approval significantly advances the standard of care for chronic hepatitis C in Japan, as it eliminates the need for interferon and ribavirin, which can be difficult to take and to tolerate, and offers the majority of people with genotype 1 infection to be cured in as little as 12 weeks with a once-daily pill,” said Professor Masashi Mizokami, MD, PhD, The Research Center for Hepatitis and Immunology, National Center for Global Health and Medicine, Ichikawa, Japan.

Primarily due to HCV, Japan has one of the highest rates of liver cancer of any industrialized country. Of the more than one million people in Japan chronically infected with HCV, 70-80 percent are infected with the genotype 1 strain of the virus.

Harvoni’s approval in Japan is supported by data from 318 treatment-naïve and treatment-experienced Japanese patients with genotype 1 HCV infection randomized to ledipasvir/sofosbuvir (n=157) or ledipasvir/sofosbuvir plus ribavirin (n=161) in the Phase 3 clinical trial GS-US-337-0113. Of the 318 patients enrolled in this study, 34 percent were ages 65 years or older and 23 percent had cirrhosis.

Among patients receiving 12 weeks of ledipasvir/sofosbuvir without ribavirin, 100 percent (n=78/78) of treatment-naïve and 100 percent (n=79/79) of treatment-experienced patients achieved sustained virologic response 12 weeks after completing therapy (SVR12). Adverse events observed with ledipasvir/sofosbuvir without ribavirin were generally mild and included nasopharyngitis (29 percent), headache (7 percent) and malaise (6 percent).

The approval is also supported by results from three Phase 3 studies (ION-1, ION-2 and ION-3) evaluating eight, 12 or 24 weeks of ledipasvir/sofosbuvir among genotype 1 HCV patients. Trial participants included patients from the United States, Europe and Puerto Rico who were treatment-naïve or who had failed previous treatment, including protease inhibitor-based regimens, and also included patients with compensated cirrhosis. Trial participants in the ribavirin-free arms (n=1,080) achieved SVR12 rates of 94 to 99 percent.

“Harvoni is a safe, simple and well-tolerated treatment. With cure rates of up to 100 percent and without the need for interferon or ribavirin, it offers genotype 1-infected patients a high likelihood of cure,” said Norbert Bischofberger, PhD, Gilead’s Executive Vice President, Research and Development, and Chief Scientific Officer. “We are pleased to have partnered with the medical community in Japan to demonstrate the safety and efficacy of two significant advances in the treatment of chronic hepatitis C – Harvoni for genotype 1 infection and Sovaldi for genotype 2 infection, which was approved just three months ago. We look forward to making Harvoni available in Japan as quickly as possible.”

EASL 2015: Part 2 —Alan Franciscus, Editor-in-Chief

In part 2 of our European Association for the Study of the Liver (EASL) coverage I will wrap up with a brief overview of some of the remaining data. 

AbbVie:  Ombitasvir/Paritaprevir/Ritonavir for Treatment of HCV Genotype 1b In Japanese Patients with or without Cirrhosis: Results from Gift-I –K Chayama et al

In this current study, Japanese patients were treated with AbbVie’s 2D (paritaprevir/ritonavir plus ombitasvir) given once-a-day for 12 weeks.  This is different from the 3D regime given in the United States and elsewhere because Japanese patients metabolize AbbVie’s drugs differently.  With the 2D combinations Japanese patients reach high enough levels even without ribavirin or dasabuvir.    

In the study there were 215 HCV genotype 1b patients who received the study drugs, 42% were cirrhotic, and 35% were treatment experienced.  The overall cure rate was 95%.  The cure rates among those who had never been treated, as well as those who were treated previously (cirrhotic and non-cirrhotic) were all similar.  The most common side effects were headache, edema and sore throat. 

Comments:  Japan has a long history of hepatitis C.  AbbVie’s 2D combination will be a welcome addition to the drugs in Japan to treat Japanese patients.  For more information about HCV in Japan check out our HCV in Japan—HCV Around the World series.

 

NHANES:  Advanced Fibrosis is Common in Individuals whose Hepatitis C Has Not Been Diagnosed: Results from the National Health and Nutrition Examination Survey 2001-2012—P Udompap et al

This study has been reported at previous conferences, but it is worth discussing again.  The National Health and Nutrition Examination Survey (NHANES) used data from a group of 62,000 American adults of whom 45,000 were tested for hepatitis C antibodies—591 tested antibody positive and of those 420 were HCV RNA or viral load positive. 

Of the 420 who had chronic hepatitis C, 1 in 10 had cirrhosis and 1 in 5 had advanced fibrosis.  Approximately 50% did not know that they had hepatitis C. 

Comments:  This validates the recommendation for “Baby Boomer” testing.  This should WAKE UP the complacency among physicians and associations and start testing baby boomers NOW.  We want to test, monitor, treat, cure and save lives.

 

Gilead:  Ledipasvir/sofosbuvir treatment results in high SVR rates in patients with chronic genotype 4 and 5 HCV infection— A Abergel et al

A total of 44 HCV genotype 4 patients and 41 HCV genotype 5 patients were treated with the combination of sofosbuvir and ledipasvir for 12 weeks.  In both of the groups the patients were evenly divided between treatment experienced (TE) and those who had never been treated (TN) and those with and without cirrhosis (C & w/o C).  The cure rates in the HCV genotype 4 patients was TN =96% (21 of 22 pts); TE = 91% (20 of 22 pts); C= 100% (10 of 10 pts); w/o C = 91% (31 of 34 pts).  The most common side effects were fatigue and headache.

 

Comments:  These are very good cure rates with few side effects.  While the population of genotype 4 and 5 in the United States is very low—genotype 4 is very high in Egypt and other parts of the world (see HCV in Egypt in our HCV Around the World series).  Genotype 5 is primarily seen in South Africa and parts of Europe.  I will be writing an article on Genotype 5 for the June Mid-Monthly edition so stay-tuned.

 

Merck: The Phase 3 C-Edge Treatment-Naive (TN) Study of a 12-Week Oral Regimen of Grazoprevir (GZR, MK-5172)/Elbasvir (EBR, MK-8742) in Patients with Chronic HCV Genotype (Gt) 1, 4, or 6 Infection—S Zeuzem et al

This was a phase 3 study of a one pill, once-a-day grazoprevir and elbasvir pill taken for 12 weeks.  The study included treatment naïve (TN). The trial included a total of 421 infected HCV genotype 1, 4 or 6.  Most of the trial participants were male sex, and White.  Ninety-one percent were genotype 1.   Approximately 22% had cirrhosis. 

The overall cure rate was 95%: 92% for genotype 1a and 99% for genotype 1b; 100% (36 of 36 pts) of the genotype 4 patients were cured; 80% (5 of 6 pts) of genotype 6 patients were cured.  The most common side effects were headache, fatigue, nausea and joint pain.

 
Comments:  These are high cure rates with a low side effect profile and it will make a good addition to the treatment landscape of HCV in 2016.  In people with the genotype 1a NS5A resistance-associated variants (RAVs) it shows greater than a 5-fold loss in sensitivity to elbasvir (a protease inhibitor).  What this means in clinical practice in unknown at this time.

AbbVie Presents New Data for its Investigational Hepatitis C Treatment in Japanese Patients With and Without Cirrhosis

- New data from GIFT-I study presented at the Annual Meeting of the Japan Society of Hepatology

- Primary endpoint of 95 percent and secondary endpoint of 91 percent SVR12 achieved in genotype 1b hepatitis C virus infected Japanese patients without and with compensated cirrhosis, respectively(1)

- 98 percent SVR12 achieved in additional analysis of patients without cirrhosis receiving double-blind placebo for 12 weeks, followed by open-label therapy with AbbVie's investigational treatment(1)

- AbbVie's ribavirin-free treatment for genotype 1 hepatitis C Japanese patients consists of a 12-week, two direct-acting antiviral, fixed-dosed combination of paritaprevir/ritonavir with ombitasvir, dosed once daily

NORTH CHICAGO, Ill., May 26, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV) presented new results from the Phase 3 GIFT-I study of its investigational, all-oral, interferon (IFN)- and ribavirin (RBV)-free, two direct-acting antiviral treatment with ombitasvir/paritaprevir/ritonavir at the Annual Meeting of the Japan Society of Hepatology in Kumamoto, Japan.¹ GIFT-I evaluated genotype 1b (GT1b) chronic hepatitis C virus (HCV) infected Japanese patients, with and without cirrhosis, who were either treatment-naïve or IFN (with or without RBV) treatment-experienced.¹ The primary endpoint was achieved, demonstrating 95 percent (n=106/112) SVR₁₂ in a sub-group of treatment-naïve, non-cirrhotic, adult GT1b HCV infected Japanese patients who were eligible for therapy with IFN and had a high viral load.¹ In study results related to the secondary endpoint, GT1b HCV patients with compensated cirrhosis achieved 91 percent (n=38/42) SVR₁₂.¹

In an additional intent-to-treat (ITT) analysis, SVR₁₂ was achieved in 98 percent (n=104/106) of the GT1b HCV infected patients without cirrhosis (Arm B) who were randomized to initially receive double-blind placebo for 12 weeks, followed by open-label treatment with ombitasvir/paritaprevir/ritonavir.¹ The ITT population included every patient that was randomized to placebo and received at least one dose of active, open-label study drug.

"It is critical to address the burden of hepatitis C in Japan, with GT1b being the most prevalent sub-type of the disease in the country," said Kazuaki Chayama, M.D., Ph.D, professor and head of the Department of Gastroenterology and Metabolism, Graduate School of Biomedical and Health Sciences, Hiroshima University. "GIFT-I shows the potential of this treatment to achieve high SVR rates for Japanese patients with GT1b hepatitis C, including those with compensated cirrhosis."

Across all study arms, three patients (n=3/363) discontinued treatment due to adverse events.¹ The most commonly reported adverse events (>5 percent in any arm) were nasopharyngitis, headache, peripheral edema, nausea, pyrexia and decreased platelet count.¹

"We are pleased to present full results from GIFT-I, which provide further insight into our hepatitis C treatment currently under priority review by the Japanese health authorities," said Scott Brun, M.D., vice president, pharmaceutical development, AbbVie. "We know physicians weigh the risks and benefits of HCV treatments for their patients as they look for an option that offers a potential cure. These data will help guide clinicians in their decision making and support AbbVie's goal of bringing an interferon- and ribavirin-free treatment to people living with genotype 1 hepatitis C in Japan."

In Japan, approximately 1.5 to 2 million people are living with HCV.² Genotype 1 is the most common HCV genotype in Japan with 60 to 70 percent of patients infected and, of those, about 95 percent are infected with the GT1b sub-type.³ AbbVie studied its two direct-acting antiviral treatment regimen without RBV in Japan due to patient and viral characteristics specific to the Japanese population, including high prevalence of GT1b.

AbbVie's investigational, two direct-acting antiviral treatment consists of ombitasvir/paritaprevir/ritonavir and is currently under priority review by the Japanese Ministry of Health, Labour and Welfare.

About GIFT-I Study
GIFT-I comprises 363 patients in two sub-studies. In sub-study 1, 321 genotype 1b (GT1b) patients without cirrhosis, both treatment-naïve and interferon (IFN) [with or without ribavirin (RBV)] treatment-experienced, were randomized to receive either ombitasvir/paritaprevir/ritonavir (Arm A) [OBV/PTV/r] or placebo (Arm B) [2:1 randomization ratio, stratified by treatment history, past response, viral load and IFN eligibility]. Patients initially randomized to placebo (Arm B) then received OBV/PTV/r for an additional 12 weeks of open-label treatment. Sustained virologic response was assessed 12 weeks post-treatment (SVR₁₂) as a primary efficacy endpoint in a sub-group of previously untreated, non-cirrhotic GT1b patients who were eligible for therapy with IFN and had a high viral load, defined as an HCV RNA level ≥ 100,000 IU/mL and received at least one dose of the double-blind, active study drug.¹

In sub-study 2, 42 GT1b treatment-naïve and IFN (with our without RBV) treatment-experienced patients with compensated cirrhosis received open-label treatment for 12 weeks (Arm C) with SVR₁₂ and assessed as a secondary efficacy endpoint.¹

One patient from each arm (n=3/363) experienced on-treatment virologic failure [Arm A, 0.5% (n=1/215); Arm B, 0.9% (n=1/106); Arm C, 2.4% (n=1/42)].¹ Across all arms, eight patients (n=8/354) experienced post-treatment relapse [Arm A, 2.4% (n=5/209); Arm B, 1.0% (n=1/105); Arm C, 5.0% (n=2/40)].¹

Japan’s Ministry of Health, Labour and Welfare Approves Gilead’s Sovaldi® (sofosbuvir) for the Treatment of Genotype 2 Chronic Hepatitis C

-- Sovaldi Part of First All-Oral Treatment Regimen for Genotype 2 Patients in Japan --

-- 96 Percent Cure Rates and Shortened, 12-Week Course of Therapy --

FOSTER CITY, Calif.--(BUSINESS WIRE)--Mar. 26, 2015-- Gilead Sciences, Inc. (Nasdaq:GILD) today announced that the Japanese Ministry of Health, Labour and Welfare (MHLW) has approved Sovaldi^® (sofosbuvir), a once-daily nucleotide analog polymerase inhibitor, for the suppression of viremia in patients with genotype 2 chronic hepatitis C virus (HCV) infection with or without compensated cirrhosis. Sovaldi is indicated for use in combination with ribavirin (RBV) for 12 weeks. Sovaldi (in combination with RBV) is the first all-oral, interferon-free treatment regimen for genotype 2 HCV infection. Sovaldi is also the first product to be marketed by Gilead in Japan.

“Today’s approval represents an important step forward in the management of hepatitis C in Japan, enabling genotype 2 infected patients the opportunity of a cure in 12 weeks with an all-oral regimen that eliminates the need for interferon,” said Masao Omata, MD, Yamanashi Prefectural Hospital Organization.

Primarily due to HCV, Japan has one of the highest rates of liver cancer of any industrialized country. Of the more than one million people chronically infected with HCV, 20-30 percent have the genotype 2 strain of the virus. Currently approved therapies in Japan for genotype 2 HCV infection involve 24-48 weeks of injections with pegylated interferon, which may not be suitable for many patients.

Sovaldi’s approval is supported by data from a Phase 3 clinical trial conducted in Japan (Study GS-US-334-0118) among treatment-naïve and treatment-experienced genotype 2 patients. Approval was based on 96 percent (n=135/140) of genotype 2 HCV-infected patients who received 12 weeks of an all-oral regimen of Sovaldi plus RBV 600–1,000 mg/day achieving a sustained virologic response 12 weeks after completing therapy (SVR12). Patients who achieve SVR12 are considered cured of HCV infection. The approval is also supported by SVR12 results from four international Phase 3 studies (FISSION, FUSION, POSITRON and VALENCE), which included genotype 2 HCV patients.

“There is a need in Japan for new HCV treatment options that are more effective and better tolerated and we have been pleased to partner with the medical community here in Japan to demonstrate the efficacy and safety of Sovaldi,” said Norbert Bischofberger, PhD, Gilead’s Executive Vice President, Research and Development and Chief Scientific Officer. “We look forward to making Sovaldi available in Japan as quickly as possible, while simultaneously continuing to work with the agency on its review of our second application for an all-oral sofosbuvir-based regimen for the treatment of genotype 1 HCV infection.”

Gilead filed a New Drug Application (NDA) in Japan for a single-tablet regimen of sofosbuvir and the NS5A inhibitor ledipasvir for the treatment of genotype 1 HCV infected patients on September 24, 2014. The ledipasvir/sofosbuvir single tablet regimen is an investigational product in Japan and its safety and efficacy have not yet been established.

AbbVie Submits New Drug Application in Japan for its Investigational, All-Oral, Treatment for Chronic Hepatitis C

- Submission based on Phase 3 GIFT-I study in patients with genotype 1b chronic hepatitis C virus infection

- GIFT-I met its primary endpoint, achieving 95 percent sustained virologic response rate at 12 weeks post-treatment; two patients (0.9 percent) discontinued treatment due to adverse events

- AbbVie's treatment for Japanese hepatitis C patients consists of a 12-week, two direct-acting antiviral, fixed-dose combination of paritaprevir/ritonavir with ombitasvir, dosed once daily

NORTH CHICAGO, Ill., Feb. 11, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV) submitted a New Drug Application (NDA) to the Japanese Ministry of Health, Labour and Welfare (MHLW) seeking approval for the company's investigational, all-oral, ribavirin (RBV) and interferon (IFN)-free, 12-week, two direct-acting antiviral treatment of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r), dosed once daily. The submission is for the treatment of patients with genotype 1 (GT1) chronic hepatitis C virus (HCV) infection.

The NDA is supported by the Phase 3 GIFT-I study, which met its primary endpoint, achieving a 95 percent (n=106/112) sustained virologic response rate at 12 weeks post-treatment (SVR₁₂) in the sub-group of previously untreated, non-cirrhotic, adult genotype 1b (GT1b)-infected Japanese patients who were eligible for therapy with IFN and had a high viral load (≥ 100,000 IU/mL). Additionally, two patients without cirrhosis (0.9 percent) discontinued treatment due to adverse events. GIFT-I included a placebo-controlled arm and studied patients with and without compensated cirrhosis, who were new to therapy or treatment-experienced (with IFN and with or without RBV).

"We are pleased to announce the regulatory submission of our two direct-acting hepatitis C antiviral treatment in Japan, which follows on quickly from recent approvals of our three direct-acting antiviral treatment in the U.S., Canada and the European Union," said Scott Brun, M.D., vice president, pharmaceutical development, AbbVie. "This submission is based on a large Phase 3 study in multiple patient types and brings us closer to offering the possibility of cure for patients with chronic genotype 1b hepatitis C infection, the most common form of the disease in the country."

AbbVie studied a two direct-acting antiviral regimen without RBV in Japan due to patient and viral characteristics specific to the Japanese population, including high prevalence of GT1b. In Japan, approximately 1.5 to 2 million people are living with HCV.¹ Genotype 1 is the most common HCV genotype in Japan with 60 to 70 percent of patients infected and, of those, about 95 percent are infected with the GT1b sub-type.²

About the GIFT-I Study GIFT-I (M13-004) is a Phase 3, multi-center study designed to evaluate the efficacy and safety of 12 weeks of treatment with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in adult Japanese patients (n=363) with chronic genotype 1b hepatitis C virus infection. Patients included those without cirrhosis and with compensated cirrhosis, who were new to therapy (treatment-naïve) or had failed previous treatment with interferon with or without ribavirin (treatment-experienced).

The study consists of two sub-studies. Sub-study one included patients without cirrhosis randomized to OBV/PTV/r or placebo. Sub-study two included patients with compensated cirrhosis, who received open-label treatment with OBV/PTV/r.

Within the primary efficacy patient population, there were no on-treatment virologic failures and 2.8 percent of patients (n=3/109) experienced relapse.

In patients without cirrhosis, the most commonly reported adverse events in the treatment arm were nasopharyngitis (16.7 percent OBV/PTV/r vs. 13.2 percent placebo), headache (8.8 percent OBV/PTV/r vs. 9.4 percent placebo), and oedema peripheral (5.1 percent OBV/PTV/r vs. 0 percent placebo).

Jan 30, 2015

- 95 percent SVR₁₂ rate achieved in Japanese patients new to therapy with genotype 1b chronic hepatitis C virus infection without cirrhosis and with a high viral load

- Regulatory filing in Japan planned for the first quarter of 2015

NORTH CHICAGO, Ill., Jan. 30, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV) released top-line Phase 3 results for its investigational, all-oral, ribavirin (RBV)-free, two direct-acting antiviral treatment with ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) in patients with genotype 1b (GT1b) chronic hepatitis C virus (HCV) infection in Japan. The primary endpoint of the GIFT-I study was achieved, demonstrating a 95 percent (n=106/112) sustained virologic response rate at 12 weeks post treatment (SVR₁₂) in the sub-group of previously untreated, non-cirrhotic adult GT1b Japanese patients who were eligible for therapy with interferon (IFN) and had a high viral load.

"AbbVie is committed to advancing HCV care with the goal of evaluating our treatment in a broad range of patients around the world," said Scott Brun, M.D., vice president, pharmaceutical development, AbbVie. "The GIFT-I results are encouraging and support moving forward with our Japan development program, with a local regulatory submission anticipated in the first quarter of 2015."

In Japan, up to two million people are currently living with hepatitis C.¹ Genotype 1b is the most common sub-genotype, affecting nearly half of the people infected with HCV.²

In the GIFT-I study, the primary efficacy population comprised a sub-group of treatment-naive GT1b chronic HCV infected patient population. This sub-group consisted of treatment-naive patients without cirrhosis who were eligible for therapy with IFN with or without RBV, had a high viral load (> 100,000 IU/mL) and received at least one dose of the double-blind active study drug. The primary endpoint was assessed at 12 weeks post treatment (SVR₁₂).

In patients without cirrhosis, the most commonly reported adverse events in the treatment arm were nasopharyngitis (16.7 percent OBV/PTV/r vs. 13.2 percent placebo), headache (8.8 percent OBV/PTV/r vs. 9.4 percent placebo), and oedema peripheral (5.1 percent OBV/PTV/r vs. 0 percent placebo). Two patients without cirrhosis (0.9 percent) discontinued treatment due to adverse events.
Within the primary efficacy patient population, there were no on-treatment virologic failures and 2.8 percent of patients (n=3/109) experienced relapse.

AbbVie will disclose detailed GIFT-I study results at future scientific congresses and in publications.
