Direct-Acting Antivirals with Excellent Efficacy and Favourable Safety, Represent a Unique Opportunity to Achieve HCV Elimination The French and European Approach Towards Hepatitis C Virus Elimination HEPDART 2017 USA December 3rd, 2017 Tarik Asselah (MD, PhD) Professor of Medicine Hepatology, Chief INSERM UMR 1149, Hôpital Beaujon, Clichy, France. Disclosures • Employee of Paris Public University Hospitals (AP-H P, Beaujon’s Hospital) and University of Paris • Principal investigator for research grants : Funds paid to Hospital (AP-HP) • Consultant, expert and speaker for: Abbvie, Bristol-Myers Squibb, Gilead, Janssen, Merck Sharp Dohme, Roche. • Grants from : ANR, CNRS , INSERM , University of Paris, ANRS 2 The French and European Approach Towards Hepatitis C Virus Elimination The goal of this lecture will be to present the situation of HCV in Europe and in France. Direct-acting antivirals with excellent efficacy and favourable safety, represent a unique opportunity to achieve HCV elimination. We will discuss the European & French approach towards Hepatitis Programs and to identify models to achieve Elimination.

  • Hepatitis Central.Com 2016 Was an Amazing Year for Hepatitis C Drug Progress
    Hepatitis C – Hepatitis Central.Com 2016 was an amazing year for Hepatitis C drug progress. In 2016, Harvoni and Viekira Pak were the most likely prescribed Hepatitis C medications. In addition, Zepatier, Viekira XR, Technivie and Epclusa were approved by the FDA to treat Hepatitis C. Used for different Hepatitis C genotypes, these medications boast a very high success rate, eliminating the Hepatitis C virus in 95 to 100 percent of patients. However, there is always room for improvement. The following pharmaceutical companies are leading the way: Gilead This combination consists of sofosbuvir, velpatasvir and voxilaprevir to treat people who had failed previous therapies and to provide higher cure rates for those who had not been previously treated (genotypes 1 through 6). The cure rates in phase 3 clinical trials were 95 to 98 percent. This led to being granted Breakthrough Therapy designation by the FDA for those with genotype 1 who had failed a previous course of therapy that contained a NS5A inhibitor and being submitted in December 2016 for approval to treat all genotypes. AbbVie The combination of glecaprevir (ABT-493) plus pibrentasvir (ABT-530) was used to treat genotypes 1, 3, 4, 5 and 6 for a duration of just eight weeks. This combination was granted Breakthrough Therapy designation by the FDA for those with genotype 1 who had failed a previous course of therapy that contained a NS5A inhibitor. In December 2016 AbbVie applied to the FDA to market and treat all Hepatitis C genotypes with this drug combination. Janssen • Samatasvir – currently in phase 1 development for genotypes 1, 2, 3 and 4, and in a phase II study with Olysio (simeprevir) in treatment-naı̈ve patients with genotype 1b or 4.

Previous treatment options were limited to interferon and ribavirin (RBV) Mark W Sonderup3 regimens, which gave low cure rates and were associated with unpleasant side effects. The era of Nicola A Cook1 direct-acting antiviral (DAA) therapies began with the development of first-generation NS3/4A protease inhibitors in 2011. They vastly improved outcomes for patients, particularly those with Imam Waked2 genotype 1 infection, the most prevalent genotype globally. Since then, a multitude of DAAs have C Wendy Spearman3 been licensed for use, and outcomes for patients have improved further, with fewer side effects and 1 Simon D Taylor-Robinson cure rates approaching 100%.

  • Therapeutic Strategies for Recent Hepatitis C Virus Infection in the Era of Direct-Acting Antiviral Therapy
    Therapeutic strategies for recent hepatitis C virus infection in the era of direct-acting antiviral therapy Marianne Martinello A thesis in fulfilment of the requirements for the degree of Doctor of Philosophy The Kirby Institute Faculty of Medicine May 2017 Page 1 of 309 Thesis/Dissertation Sheet THE UNIVERSITY OF NEW SOUTH WALES Thesis/Dissertation Sheet Surname or Family name: Martinello First name: Marianne Abbreviation for degree as given in the University calendar: PhD School: Kirby Institute Faculty: Medicine Title: Therapeutic strategies for recent hepatitis C virus infection in the era of direct-acting antiviral therapy Abstract: Background: The management of recent hepatitis C virus (HCV) infection is uncertain, as the therapeutic landscape evolves with the advent of direct-acting antiviral (DAA) therapy. Aims: The broad aim of this research was to examine novel therapeutic strategies in recent HCV following the availability of DAA therapy. Specific aims included assessing the feasibility, efficacy and safety of response-guided interferon (IFN) -containing and ultra-short IFN-free therapy; calculating reinfection incidence following treatment; and determining the clinical significance of drug-drug interactions in HIV/HCV co-infection. Methods: In Chapters Two and Three, the efficacy and safety of short and/or response-guided treatment among individuals with recent HCV was examined in three open-label trials: ATAHC II (n=52; pegylated-IFN +/- ribavirin), DARE-C I (n=14; pegylated-IFN, ribavirin + telaprevir) and DARE-C II (n=19; sofosbuvir + ribavirin). In Chapter Four, reinfection incidence following treatment for recent HCV was calculated among those who achieved an end-of-treatment response in ATAHC I and II, DARE-C I and II (n=120).

    Special Lecture 2. Special Lecture 2. Hepatitis C Virus: Next Generation of DAAs Mark Sulkowski Professor of Medicine Divisions of Infectious Diseases and Gastroenterology/Hepatology Johns Hopkins University School of Medicine Medical Director, Viral Hepatitis Center Johns Hopkins Hospital Baltimore Maryland USA In the current era, multiple HCV treatment regimens have been developed that are interferon-free and deliver high rates of HCV cure (> 95%) in most patient populations with treatment durations in the range of 12 weeks. In the context, the question can and should be asked: Is there a medical need for a next generation of DAAs. In short, the answer is that novel drugs and drug regimens are needed for certain patient populations including 1) Person who failed to achieve HCV cure with current DAAs need “salvage” regimens that can overcome HCV drug resistance associated variants (RAVs); 2) HCV genotype 3 for whom the treat- ment options are limited; 3) Persons for whom ribavirin is still recommended including those with HCV genotype 2 and some patients with cirrhosis. HCV NS3 Protease inhibitors. The first wave of HCV protease inhibitors – telaprevir, boceprevir and simeprevir – are not pan- genotypic, lacking potent antiviral activity against HCV genotype 3. There are two protease inhibitors in phase 3 clinical trials that are once daily, potent, pangenotypic drugs: Voxilaprevir (VOX, GS-9857) and ABT-493. Voxilaprevir is being developed as a fixed-dose combination tablet including sofosbuvir and velpatasvir (a pangenotypic NS5A inhibitor). ABT-493 is being devel- oped as a fixed-dose combination tablet including ABT-530 (a pangenotypic NS5A inhibitor). Both regimens are currently being evaluated in phase 3 clinical trials for treatment durations of 8 and 12 weeks in persons with all HCV genotypes and in those who failed DAA regimens.
