Medivir: An all-oral phase IIa study combining Simeprevir, TMC647055 and JNJ56914845 in hepatitis C patients to be initiated

STOCKHOLM --(Business Wire)--

Medivir AB (STO:MVIR-B) (OMX: MVIR), announces the initiation of a phase IIa trial in chronic genotype 1 hepatitis C infected patients to evaluate the efficacy, safety and tolerability of a 12-week combination therapy of simeprevir, TMC647055 and JNJ56914845, a NS5A replication complex inhibitor.

Study design

Approximately 40 patients will be enrolled in this open-label study to assess the efficacy, safety and tolerability of the co-administration of simeprevir, TMC647055 and two different doses of JNJ56914845 without ribavirin. The trial will evaluate genotype 1a and 1b HCV-infected patients who are either treatment-na�ve or who have relapsed after prior treatment with interferon and ribavirin. Patients will receive 75 mg of simeprevir, 30 or 60 mg of JNJ56914845 and 450 mg of TMC647055 plus a low dose of ritonavir as a pharmacokinetic enhancer, each once daily for 12 weeks.

Simeprevir was approved for the treatment of genotype 1 hepatitis C in September 2013 in Japan and in the USA and Canada in November. A Marketing Authorisation Application was submitted to the European Medicines Agency (EMA (News - Alert)) in April 2013 by Janssen-Cilag International NV seeking approval of simeprevir for the treatment of genotype 1 or genotype 4 chronic hepatitis C. To date, more than 3,700 patients have been treated with simeprevir in clinical trials.
