Janssen Scraps Hep C Therapy Due to Saturated Market
Janssen Sciences has decided to discontinue development of its investigational hepatitis C treatment regimen JNJ-4178, a combination of three direct-acting antivirals — AL-335, odalasvir and simeprevir. While ongoing Phase 2 studies with JNJ-4178 will be completed as planned, the decision to abandon the program is based on “increasing availability of a number of highly effective therapies addressing the medical need in hepatitis C,” the company says.
Janssen previously co-developed telaprevir, a first-in-class protease inhibitor used in combination therapy for the treatment of chronic hepatitis C virus. In partnership with Medivir AB, Janssen subsequently developed and launched a second generation protease inhibitor, Olysio (simeprevir).
