--Expanded indication includes both treatment-naive and treatment-experienced adult patients with or without cirrhosis--

TITUSVILLE, N.J., Nov. 5, 2014 /PRNewswire/ -- Janssen Therapeutics, Division of Janssen Products, LP (Janssen) announced the U.S. Food and Drug Administration (FDA) has approved OLYSIO® (simeprevir), a hepatitis C virus (HCV) NS3/4A protease inhibitor, in combination with sofosbuvir as an all-oral, interferon- and ribavirin-free treatment option for genotype 1 chronic hepatitis C (CHC) infection in adult patients as part of a combination antiviral treatment regimen. Sofosbuvir is an HCV nucleotide analog NS5B polymerase inhibitor developed by Gilead Sciences, Inc.

HCV is a blood-born infectious disease of the liver that affects an estimated 3.2 million people in the U.S.[1] Approximately 75 to 85 percent of people who become infected with HCV develop chronic infection.[2] Most persons with CHC infection are asymptomatic, which means they do not show symptoms of the disease.[3] When left untreated, CHC infection may cause significant liver damage, including cirrhosis, which is severe scarring of the liver. CHC may also increase the risk of developing complications from cirrhosis, which may include liver failure.[4]

Data supporting the OLYSIO® and sofosbuvir combination regimen are from the COSMOS study, an open-label, randomized Phase 2 clinical trial that investigated the efficacy and safety of 12 or 24 weeks of OLYSIO® (150 mg once daily) in combination with sofosbuvir (400 mg once daily) with or without ribavirin in HCV genotype 1 chronically infected treatment-naive and treatment-experienced adult patients with compensated liver disease.

"It's a very encouraging time for patients with chronic hepatitis as the advent of new direct-acting treatment combinations, like OLYSIO® plus sofosbuvir offer all-oral, interferon- and ribavirin-free treatment options," said Eric Lawitz, M.D., primary investigator for the COSMOS clinical study, and vice president, Scientific and Research Development, The Texas Liver Institute and professor of medicine, University of Texas Health Science Center. "The availability of multiple treatment options is important to physicians and patients so optimal treatment decisions can be made, given the complexity of the disease and diversity of patient population."

"I lived with hepatitis C for nearly thirty years," said Norman Walsh, a COSMOS clinical trial patient. "I will never forget the moment that my clinical trial healthcare team told me the news following my treatment with the combination of OLYSIO® and sofosbuvir. I was elated, relieved – and cured."*

OLYSIO® in Combination with Sofosbuvir in HCV Adult, Genotype 1 Patients
The recommended treatment duration of OLYSIO® with sofosbuvir is 12 weeks for patients without cirrhosis or 24 weeks for patients with cirrhosis.

The data for this expanded indication are based on two cohorts in the COSMOS study, published in The Lancet. Cohort 1 included prior non-responder patients (patients who failed prior interferon-based therapy) with no to moderate liver fibrosis (defined as METAVIR F0 to F2 scores), and Cohort 2 included treatment-naive patients (patients who have not received other treatments previously) and prior non-responder patients to peginterferon alfa and ribavirin near cirrhosis (METAVIR F3) and with cirrhosis (METAVIR F4). METAVIR scores measure the severity or stage of liver fibrosis, from early to advanced.

In pooled analyses of both cohorts, 95 percent of patients (20/21) with METAVIR F0-F3 receiving 12 weeks of OLYSIO® with sofosbuvir achieved sustained virologic response (SVR12) or cure, the absence of HCV detected in the blood 12 weeks after the end of treatment. Viral relapse occurred in 5 percent (1/21) and 0 percent (0/20) of patients with METAVIR F0-F3 after 12 or 24 weeks of combination therapy, respectively. Regardless of whether patients were treatment-naive or treatment-experienced, 86 percent of patients (6/7) with METAVIR F4 receiving 12 weeks of OLYSIO® in combination with sofosbuvir achieved SVR12, while 100 percent of patients (10/10) with cirrhosis who were treated with the combination for 24 weeks achieved SVR12. Viral relapse occurred in 14 percent (1/7) and 0 percent (0/10) of patients with cirrhosis after 12 or 24 weeks of combination therapy, respectively.

For all patients in the COSMOS trial (treatment-naive and treatment-experienced, METAVIR F0-F4), 93 percent (26/28) achieved SVR12 after 12 weeks and 97 percent (30/31) achieved SVR12 after 24 weeks of treatment. Viral relapse occurred in 7 percent of patients (2/28) after 12 weeks and 0 percent of patients (0/30) after 24 weeks of treatment overall.

In the COSMOS trial, the most common (> 10 percent) adverse reactions reported during 12 weeks of treatment with OLYSIO® in combination with sofosbuvir without ribavirin were fatigue (25 percent), headache (21 percent), nausea (21 percent), insomnia (14 percent) and pruritus (11 percent). Rash and photosensitivity were reported in 11 percent and 7 percent of patients, respectively. During 24 weeks of treatment with OLYSIO® in combination with sofosbuvir, dizziness (16 percent), and diarrhea (16 percent) were also commonly reported.

Prior to initiation of treatment with OLYSIO® with sofosbuvir, screening patients infected with HCV genotype 1a for the presence of virus with the NS3 Q80K polymorphism is not strongly recommended but may be considered.

Janssen is continuing its clinical development program for OLYSIO®, including Phase 3 study commitments. For more information please visit www.clinicaltrials.gov.

"We're pleased that an interferon-free, ribavirin-free OLYSIO®-based combination is now approved in the United States for patients with genotype 1 chronic hepatitis C infection. The availability of multiple treatment options is important to help offer an opportunity for cure and we believe OLYSIO® will play a meaningful role in this respect," said Gaston Picchio, PhD., Hepatitis disease area leader, Janssen Research & Development, LLC. "We're passionate about finding new treatment options for patients living with hepatitis C worldwide and will continue to pursue innovative approaches to help address this disease."

Access and Support for OLYSIO®
Janssen partners with a variety of stakeholders to support patient access and compliance to medicines. A substantial part of this effort is working closely with public and private payers to ensure that patients who need OLYSIO® can obtain access to it.

For patients, Janssen offers OLYSIO® Support, a comprehensive support program designed to assist in the HCV treatment journey so that they, their caregivers and their healthcare providers can help them focus on treatment. OLYSIO® Support provides benefit verifications, assistance with the prior authorization process, and information about a variety of affordability programs, including those for patients with commercial insurance, federally-funded insurance or no insurance coverage.

Eligible patients with commercial insurance coverage for OLYSIO® may pay only $5 per fill with the OLYSIO® Savings Card. This is subject to a $50,000 annual maximum benefit or 12 months from the card activation date, whichever comes first. For more information about OLYSIO® Support, visit www.OLYSIO.com or call 1-855-5-OLYSIO (1-855-565-9746), 8 a.m. - 8 p.m. (EST), Monday through Friday.

"The approval of OLYSIO® in combination with sofosbuvir is welcome news for people living with chronic hepatitis C infection and their families," said Gloria Searson, ACSW, founder and president, Coalition on Positive Health Empowerment (COPE). "As an organization focused on serving people trying to make sense of their HCV diagnosis, we're encouraged by the work Janssen is doing to provide new treatment options and support programs to help patients navigate their journey."**

GSK hepatitis C shot shows promise, bodes well for Ebola vaccines

By Kate Kelland

LONDON Thu Nov 6, 2014 12:31am IST

(Reuters) - A new hepatitis C vaccine from GlaxoSmithKline based on the same technology as an experimental Ebola shot being fast-tracked through human trials has shown promise in early clinical tests, prompting strong and broad immune responses.

Researchers testing the vaccine -- the first hepatitis C vaccine to reach second stage clinical trials -- said their results in a group of 15 healthy human volunteers showed it was very safe and well tolerated, and generated immune responses of a strength never seen before in a vaccine against this disease.

"This is as good at it could be for a first go, and I'm optimistic that it will work (in second stage trials)," said Ellie Barnes, a professor at Britain's Oxford University who led the initial human tests.

She said results also bode well for GSK's experimental Ebola vaccine currently being tested in healthy volunteers in Britain, Africa and the United States, as well as another experimental Ebola shot from Johnson & Johnson.

The vaccines are based on similar science, using a common cold virus called an adenovirus to take the key ingredient into the cells.

The idea is that the adenovirus infects cells in a vaccinated person, causing them to take up genes from the target virus - be it Ebola or hepatitis C - and produce their proteins.

This primes the immune system to attack the proteins of the pathogenic viruses when an infection occurs.

"What's special about adenovirus vaccines is that they are trying to induce a totally separate part of the immune response -- the T-cells," Barnes explained in a telephone interview. "And T-cells target the inner machinery of a pathogen."

Publishing their results in the journal Science Translational Medicine on Wednesday, Barnes' team explained that the hepatitis C vaccine uses a "prime-boost" strategy with two separate vaccine formulations.

CLEAR THE VIRUS

The first, or prime, vaccine is based on a chimpanzee adenovirus called ChAd3 developed by the Italian biotech firm Okairos -- now owned by GSK -- to which genes encoding four proteins from hepatitis C are added.

The second, or boost, vaccine adds the same four hepatitis C genes to a different viral vaccine base -- a so-called modified vaccininia Ankara (MVA) virus.

Neither the adenovirus nor MVA is able to replicate, so they cannot cause infection. The four genes packaged up inside cannot cause a hepatitis C infection either.

An estimated 180 million people worldwide are infected with hepatitis C, a chronic infection where the virus stays in the body for many years. It is a leading cause of liver cirrhosis and can in some cases lead to liver failure and liver cancer.

However, around a quarter of people infected are naturally able to clear the virus from their body. This suggests it is possible for the body to mount an immune response to fight off the infection.

"In our lab we spent a lot of time looking at the immune response of people who are able to clear the virus," Barnes said. "We know from that work that you need a strong immune response that targets multiple parts of the virus and that is sustained over time -- and those are the characteristics that we've been able to reproduce in this vaccine trial."

Leading drugmakers said last month they will work together to speed the development of an Ebola vaccine designed to help beat a vast epidemic of the disease which has killed more than 5,000 people, mainly in Guinea, Sierra Leone and Liberia.

Clinical tests on GSK's vaccine and another from NewLink Genetics are under way, while human tests on J&J's vaccine will start in January.

What's Hot at the Liver Meeting 2014

Medscape Medical News > Conference News

Neil Osterweil

November 04, 2014

BOSTON — The 2014 Liver Meeting returns to Boston, home of splendors such as beans, cod, the Boston Red Sox, world-class medical centers, and pharmaceutical research hubs.

The meeting, during which the American Association for the Study of Liver Diseases (AASLD) struts it stuff each year, will be held at the John B. Hynes Veterans Memorial Convention Center from November 7 to 11.

The Hynes, sandwiched between Boylston Street — the city's liveliest thoroughfare — and the hotels, shops, and restaurants of the Prudential Center complex, has hosted many previous Liver Meetings, and is ideally located to take advantage of the wealth of science the conference provides and all of the amenities that Boston has to offer.

Nearly 3000 abstracts were submitted by clinicians and scientists for this year's event, covering the latest clinical trial results, practice-changing clinical findings, and basic research into the mechanisms and molecular targets of diseases of the liver.

"We're going to hear a lot about fatty liver disease; the number of abstracts about fatty liver disease this year just exploded, as did the number of abstracts about complications of cirrhosis," Gary Davis, MD, AASLD secretary, told Medscape Medical News.

"This reflects what people are seeing in the clinic. The buzz for hepatitis C has died down a bit, I think because the treatment is so effective now and it's so easy to administer," he said.

Cutting Edge

That the care of patients with hepatitis C would become almost routine — or indeed that such an entity as hepatitis C ever existed — would have seemed like wild fantasy 40 years ago.

But that's just what attendees can expect to hear during the President's Choice Lecture from Willis Maddrey, MD, from the University of Texas Southwestern Medical Center at Dallas.

"Dr Maddrey is always a pretty dynamic speaker," Dr Davis said.

He pointed out that Dr Maddrey has witnessed the advent of genetic research into fatty liver disease, pegylated interferons, protease inhibitors, and other discoveries in his more than 40 years in the trenches.

Of course, with the advent of effective combination therapies for hepatitis C comes the inevitable increase in costs, just as pressures for accountability and value in medical care rise.

"There will be some presentations on cost-effectiveness, but surprisingly not a lot, given all the press it has gotten over the past year, but I want to be in the room for those. I think the discussions after the abstracts are presented will be pretty good," Dr Davis said.

On a related theme, new this year will be a symposium on value-based medicine in hepatology. The session will focus on coping in the era of Accountable Care Organizations and the Affordable Care Act. Or as the Liver Meeting program describes it, "the concept of value-based medicine and the importance of returning the practice of hepatology to its appropriate focus: enabling the health and effective care of patients with liver disease."

The $1000-per-dose therapies for hepatitis C viral infections are a challenge in this era.

The Thomas E. Starzl Transplant Surgery State-of-the-Art Lecture, by Jean Edmond, MD, from New York Presbyterian Hospital and Columbia Medical Center in New York City, will focus on the controversial topic of living-donor transplantation. Dr Edmond will outline patient and donor selection and describe the most up-to-date methods of harvesting and transplantation.

The Emerging Trends Symposium, which will follow Dr Edmond's talk, will center on a topic that might be new to some conference goers: acute on chronic liver failure. The condition is defined as acute decompensation of a patient with cirrhosis and characterized by multiple organ failure. Attendees will learn about the pathophysiology of acute liver failure, clinical issues associated with the syndrome, and investigational therapies.

The Hans Popper Basic Science State-of the-Art Lecture will be devoted to induced pluripotent stem cells and their use in the study of liver disease and development. Stephen Duncan, DPhil, from the Medical College of Wisconsin in Milwaukee, is expected to describe his groundbreaking work coaxing stem cells to differentiate into hepatocytes, Dr Davis said.

Abstract Sessions and Late-Breakers

The scientific sessions kick off on Saturday, November 8, with the first of four poster sessions covering more than 2000 research projects, from basic science findings to the latest in clinical practice, drug development, and clinical trials.

Sunday will feature transplant plenary sessions, Monday basic science and clinical plenary, and Tuesday the hepatitis plenary.

Late-breaking oral abstracts will be presented on Monday afternoon, and late-breaking posters will be on view all day Monday, with presenters available from 12:30 to 3:00 pm.

This year's late-breakers will include:

  • Results of the STOPAH trial comparing steroids with pentoxifylline for alcoholic hepatitis

  • Phase 3 results from the UNITY-2 trial of an oral fixed-dose combination therapy for patients with chronic hepatitis C genotype 1 infections and compensated cirrhosis

  • Results of the phase 3 ALLY-3 study looking at an oral ribavirin-free combination for the treatment of hepatitis C genotype 3

  • A study of post-transplant direct-acting antiviral agents for hepatitis C

  • Results from a phase 3 randomized controlled trial of an enzyme replacement therapy in children and adults with lysosomal acid lipase deficiency

  • A report on a phase 2a proof-of-concept trial of a hepatitis B and hepatitis D entry inhibitor

Ticketed educational sessions will run the gamut, from endoscopy, transplantation, pediatric hepatology, and basic research, to practical matters such as competency training and career development.

As you can still hear in some of Boston's more traditional neighborhoods, this year's Liver Meeting promises to be "wicked good."

Dr Davis have disclosed no relevant financial relationships.

[+-] Article and Author Information

Ann Intern Med. 2014;161(9):634-638. doi:10.7326/M14-1211

Background: The interferon (IFN)–free regimen of sofosbuvir and ribavirin for 24 weeks was recently approved to treat chronic hepatitis C virus (HCV) genotype 1 (GT-1) infection for patients ineligible for IFN. However, sofosbuvir plus ribavirin therapy is associated with relapse in 15% to 30% of patients with HCV GT-1. Neither the mechanism of relapse nor the optimal re-treatment strategy for these patients is defined.

Objective: To assess the safety and efficacy of sofosbuvir plus ledipasvir in patients with chronic HCV GT-1 that relapsed after sofosbuvir plus ribavirin therapy.

Design: Phase 2a, open-label study. (ClinicalTrials.gov: NCT01805882)

Setting: Single U.S site.

Patients: 14 patients with HCV GT-1 that relapsed after treatment with sofosbuvir plus ribavirin for 24 weeks were re-treated with sofosbuvir plus ledipasvir for 12 weeks.

Measurements: HCV RNA concentration and population sequencing to detect NS5B S282T mutations.

Results: All 14 patients treated with sofosbuvir plus ledipasvir for 12 weeks achieved a sustained virologic response, including 7 with advanced liver disease (Knodell Histology Activity Index score of 3 or 4) and 1 with a detectable NS5B S282T mutation after sofosbuvir plus ribavirin therapy. Sofosbuvir plus ledipasvir was well-tolerated with few adverse events. Four grade 3 events (elevated serum creatinine in a patient with baseline renal insufficiency, hypercholesterolemia, and hypophosphatemia) occurred. There were no grade 4 events or treatment discontinuations.

Limitation: Small sample size.

Conclusion: The fixed-dose combination of sofosbuvir plus ledipasvir was efficacious in a small cohort of patients with HCV GT-1 that relapsed after sofosbuvir plus ribavirin therapy, even in the setting of advanced liver disease. Larger studies are needed to confirm these preliminary efficacy results.
