Direct-acting antivirals for hepatitis C First real-life efficacy
Paris, 21 July 2015 Press release Direct-acting antivirals for hepatitis C First real-life efficacy data in HIV/HCV co-infected patients Direct-acting antivirals are revolutionizing the treatment of hepatitis C. Findings from the ANRS HEPAVIH cohort confirm for the first time their efficacy in HIV/HCV co-infected patients in a real-life setting. Twelve weeks after discontinuation of treatment, the cure rate was 93% and the treatment was well tolerated. These results will be presented by Professor Dominique Salmon (Internal Medicine and Infectious Diseases Department, Hôpital Cochin, Paris) at the 8th International AIDS Society (IAS) Conference on HIV Pathogenesis, Treatment and Prevention to be held from 19 to 22 July in Vancouver, Canada. HIV/HCV co-infection results in faster progression of chronic hepatitis C, with a 2- to 5-fold higher risk of cirrhosis compared with infection by HCV alone. Moreover, concomitant treatment of HIV and HCV raises the risk of drug interactions. Clinical trials have shown that the efficacy of direct-acting antivirals (DAAs) is similar in HIV/HCV co-infected patients and patients infected by HCV alone. It was important to confirm these results in a real-life setting and now this has been done thanks to the ANRS (France REcherche Nord&sud Sida-hiv Hépatites). With over 1600 patients in 27 clinical centers, the ANRS HEPAVIH cohort is one of the world’s largest of HIV/HCV co-infected patients. The aim was to study the characteristics of treated co-infected patients, as well as access to new anti-HCV drugs, the response to them and their safety. Professor Dominique Salmon (Internal Medicine and Infectious Diseases Department, Hôpital Cochin, Paris) and colleagues analyzed data on 76 co-infected patients of the ANRS HEPAVIH cohort in whom follow-up was sufficiently long to enable assessment of virologic control. The majority (86%) of patients showed control of HIV by antiretrovirals, but most presented advanced stage chronic hepatitis C: 80% had cirrhosis and 78% had experienced failure of a previous treatment. HCV was genotype 1 in 61% of the patients and genotype 4 in 22%. These patients had received treatment comprising one or two DAAs, combined or not with ribavirin, for 12 or 24 weeks. After this treatment, 100% of the patients presented a sustained virologic response (undetectable HCV viral load). However, relapse occurred in 5 cases during the 12 weeks following the end of treatment. The observed cure rate was therefore 93% and was similar in patients with or without cirrhosis and did not differ between HCV genotypes or according to whether or not the patients had received ribavirin or had been treated for 12 or 24 weeks. The safety of the DAAs was good, as only 38% of patients presented one or more treatment-related adverse effects (anemia in 30% of cases). Only one patient was obliged to stop treatment prematurely. “These results confirm for the first time the very good efficacy and safety of DAAs in co-infected patients followed up in real-life conditions,” explains Professor Salmon. “The efficacy observed was similar to that reported in clinical trials, whereas in our study population most patients presented advanced stage chronic hepatitis C. These findings from the ANRS HEPAVIH cohort back up current recommendations in favor of treatment with DAAs in all co-infected patients, including, and above all, those with cirrhotic hepatitis.” The 5 relapses observed in the cohort do, however, emphasize the need for heightened monitoring of HIV/HCV co-infected patients. “These relapses all occurred once treatment was finished,” points out Professor Salmon. “So it is vital to set up close monitoring of patients treated with DAAs, even after a complete virologic response following treatment, and to identify predictors of relapse, in order to avoid it.” The Research Agency ANRS (France REcherche Nord&sud Sida-hiv Hépatites) was set up in 1988. It brings together researchers from different fields and institutions in the developed world and resourcelimited countries to study scientific questions on HIV/AIDS and viral hepatitis. The ANRS funds research projects approved by international expert committees. It supports projects from conception to completion and actively participates in communicating the results to ensure that they are used for the benefit of the populations concerned. Its annual budget of approximately 45 million euros is provided by the ministries of research and health. In 2012, the ANRS became an autonomous agency of Inserm (French National Institute of Health and Medical Research).
