Active clinical trials for "Flaviviridae Infections"

This is a randomized, multicenter, 2-part, open-label trial of the combination regimen of grazoprevir (GZR [MK-5172]; 100mg), uprifosbuvir (UPR [MK-3682]; 450 mg) and ruzasvir (RZR [MK-8408]; 60 mg) with and without Ribavirin (RBV) in cirrhotic (C) or non-cirrhotic (NC) participants infected with hepatitis C virus (HCV) previously failing a direct-acting antiviral regimen (DAA). The combination regimen, referred to as MK-3682B, will be administered as two fixed-dose combination (FDC) tablets, given once-daily. The study will evaluate the efficacy of MK-3682B with or without RBV as assessed by the proportion of participants achieving Sustained Virologic Response 12 weeks (SVR12) after the end of all study therapy.

The purpose of this study is to evaluate the effectiveness of the supplementation of vitamins D and B12 in combination with Pegylated Interferon-Alfa and Ribavirin in the treatment of genotype 1 chronic hepatitis C, who do not qualify to receive protease inhibitor in Brazil.

This was a multicenter, randomized study to evaluate the safety, immunogenicity, and efficacy of VRC-ZKADNA090-00-VP (Zika virus wildtype DNA vaccine) or placebo. In Part A, the primary objective was to evaluate the safety and tolerability of the vaccine in different vaccination regimens. In Part B, the primary objectives were to evaluate the safety and efficacy of the vaccine compared to placebo.
