CROI 2012: Studies Look at Interactions Between New Hepatitis C Drugs and HIV Antiretrovirals

Drug-drug interactions between direct-acting antiviral agents for hepatitis C and some altantiretroviral medications used to treat HIV are common, but are often modest and can be managed with dose adjustments when treating people with HIV/HCV coinfection, researchers reported at the 19th Conference on Retroviruses and Opportunistic Infections (CROI 2012) last week in Seattle.

Phase 3 Trials Now Testing HCV Drug TMC435 in Genotype 1 Non-responders and Genotype 4 Patients

The next-generation hepatitis C virus (HCV) protease inhibitor TMC435 is now entering 2 new Phase 3 clinical trials, to be used in combination with pegylated interferon/ribavirin for hard-to-treat HCV genotype 1 patients as well as those with genotype 4, according to a company press release.alt

CROI 2012: Interactions between HCV Drug Daclatasvir and HIV Antiretrovirals Are Minimal or Manageable

The investigational hepatitis C virus (HCV) NS5A inhibitor daclatasvir (formerly BMS-790052) showed no clinically relevant effects on blood levels of 3 classes of antiretroviral agents, and changes in daclatasvir levels can likely be overcome by dose adjustment, according to a data presented at the 19th Conference on Retroviruses and Opportunistic Infections (CROI 2012) in Seattle.alt

CROI 2012: HIV/HCV Coinfection News from CROI 2012 [VIDEO]

Hepatitis C was a major topic at the 19th Conference on Retroviruses and Opportunistic Infections (CROI 2012) last week in Seattle. Liz Highleyman from HIVandHepatitis.com spoke with Douglas Dieterich and Kenneth Sherman about advances in the field, with a focus on HIV/HCV coinfected patients.

The attention this year was apt, since an estimated one-third of people with HIV are coinfected with hepatitis C virus (HCV). Dieterich and Mark Sulkowski presented the first data on sustained virological response (SVR) using the recently approved HCV protease inhibitors boceprevir (Victrelis) and telaprevir (Incivek) plus pegylated interferon/ribavirin in HIV/HCV coinfected patients.alt

CROI 2012: GS-7977 Rapidly Suppresses HCV, but Most Patients Relapse after Stopping Treatment

An interferon-free combination of the experimental polymerase inhibitor GS-7977 plus ribavirin potently and rapidly reduced hepatitis C virus (HCV) levels, but almost all patients experienced viral rebound after they stopped treatment, researchers reported Tuesday at the 19th Conference on Retroviruses and Opportunistic Infections (CROI 2012) this week in Seattle.alt
