Brief Summary:
This is a Phase II/III, multicenter, multi-country, trial to assess the efficacy, safety, tolerance and pharmacokinetics of sofosbuvir plus ravidasvir for the treatment of HCV infection.

Condition or disease Intervention/treatment Phase
Hepatitis C Drug: sofosbuvir + ravidasvir Phase 2 Phase 3

Detailed Description:

This is a Phase II/III, multicenter, multi-country trial to assess the efficacy, safety, tolerance and pharmacokinetics of SOF-RDV for the treatment of HCV infection, across genotypes 1,2,3,6, among non-cirrhotic and cirrhotic with CTP class A, interferon/ribavirin naïve or experienced, HCV mono-infected and HCV/HIV co-infected subjects.

It will also study the pharmacokinetics of RDV and, in HCV/HIV co-infected subjects, possible drug-drug interactions with antiretrovirals.

The treatment duration will be 12 weeks for subjects with no cirrhosis (Metavir F0 to F3) and 24 weeks for subjects with compensated cirrhosis (Metavir F4, CTP class A).

The study is performed in 2 stages. Stage 1 has been completed. Efficacy and safety results from Stage 1 were reviewed and approved by the independent Data and Safety Monitoring Board (DSMB) which provided the recommendation to proceed with the study stage 2. On-going stage 2 aims to supplement Stage 1 results and provide additional information on the performance of SOF-RDV in the main genotypes found in Malaysia and Thailand.

Drug Information available for: Sofosbuvir

Arm Intervention/treatment
Experimental: sofosbuvir + ravidasvir
12 weeks for non-cirrhotic patients, 24 weeks for cirrhotic patients
Drug: sofosbuvir + ravidasvir
combination of sofosbuvir + ravidasvir
Other Name: ravisdasvir: PPI-668

Primary Outcome Measures :
  1. Sustained Virological Response 12 weeks post treatment completion (SVR12), as evidenced by HCV RNA level less than the lower limit of quantification [ Time Frame: Outcome measure of sustained virological response will be assessed 12 weeks after the end of the treatment (SVR 12) as soon as the data will be available ]
    For patients with quantifiable HCV RNA during the post-treatment period, HCV sequences at baseline and at time of first quantifiable HCV RNA or as soon thereafter as possible will be compared to distinguish between relapses and reinfections.

Inclusion Criteria:

  • Evidence of chronic HCV infection, defined as: Positive anti-HCV antibody or detectable HCV RNA or HCV genotype at least 6 months before screening and HCV viral load ≥10^4 IU/mL at the time of screening / In subjects without documented HCV test results 6 months before screening, chronic hepatitis C infection can be assumed if risk exposures occurred > 6 months prior to screening and HCV viral load ≥10^4 IU/mL at the time of screening.
  • Willing and able to provide written informed consent.
  • Men and women age ≥ 18 years and < 70 years.
  • Body Mass Index (BMI) of 18 to 35 kg/m2.
  • Intention to comply with the dosing instructions for study drug administration and able to complete the study schedule of assessments.
  • Women with a negative pregnancy test at screening and baseline.
  • Women of child bearing potential who accept effective contraception from 2 weeks prior to study day 1 until 1 month post-treatment (Double contraceptive method including at least one barrier method). A woman is of non-child bearing potential if she (a)reached natural menopause determined retrospectively after 12 months of amenorrhea without any other obvious medical cause or (b)had procedures like bilateral tubal ligation or hysterectomy or bilateral oophorectomy.
  • Subjects who are compliant in an opioid substitution maintenance program (e.g. with methadone or buprenorphine) may be included as long as there is no concern about study medications adherence and interaction or compliance to study schedules. In stage 1, active injection drug users could also be enrolled, as a pre-stratified subpopulation, however their data did not contribute to the primary analysis.
  • Inclusion criteria related to HIV/HCV co-infected patients:

    • HIV/HCV co-infected patients receiving cART fulfilling the below criteria are eligible for the study: Antiretroviral therapy should have been initiated at least 6 months prior to screening / Patient has to have been on the same protocol-approved ARV regimen for ≥ 8 weeks prior to screening and is expected to continue the current ARV regimen through the end of study / HIV ARVs: agents allowed in this study should be administered per the prescribing information in the package insert / Screening HIV RNA < 50 copies/mL / Screening CD4 cell count ≥ 100 cells/uL
    • HIV/HCV co-infected patients not receiving cART: Screening CD4 cell count must be ≥ 500 cells/uL

Exclusion Criteria:

  • Decompensated cirrhosis defined as: Evidence of advanced stage liver cirrhosis and Child-Turcotte-Pugh (CTP) Class B or C or CTP score >6) or current/past history of decompensation including ascites, variceal bleeding, spontaneous bacterial peritonitis, or hepatic encephalopathy.
  • Hepatocellular carcinoma: for all patients with cirrhosis, hepatocellular carcinoma (HCC), should be excluded by liver imaging within 6 months prior to screening, and this must continue periodically as in routine HCC surveillance.
