Medivir initiates phase IIa trial to evaluate efficacy of simeprevir combination therapy in HCV-infected patients

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-naïve 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.
