Study to Assess Efficacy and Safety of Grazoprevir/Elbasvir Associated With Sofosbuvir and Ribavirin in HCV Genotype 1 or 4-infected Patients Who Failed Direct Acting Antivirals (DAA) Bitherapy With Sofosbuvir
France26 participantsStarted 2016-01
Plain-language summary
The primary objective of this study is to estimate, in HCV genotype 1 or 4-infected patients who failed a prior DAA bitherapy with Sofosbuvir, the efficacy of a treatment with Grazoprevir/Elbasvir, Sofosbuvir and Ribavirin in the two treatment groups and compare the rate of sustained virological response (SVR) 12 weeks after 16 or 24 weeks of this treatment. SVR12 is defined as HCV RNA \< LLOQ (either TD\[u\] or TND).

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult ≥18 years
* Infection with HCV genotype 1 or 4, confirmed by detectable HCV RNA at pre-inclusion
* Failure to a prior therapy with Sofosbuvir +/- Ribavirin associated with Simeprevir or Daclatasvir or Ledipasvir, with documented presence of NS5A or NS3/4A RAVs (Resistance Associated Variants) at the time of failure (presence of RAVs on at least one sample since the time of failure).
The proportion of patients previously treated with Simeprevir will be limited to a third of all patients included.
* Fibrosis at any stage
* Men and women of child-bearing age and their heterosexual partners must use adequate contraceptions from 15 days before their inclusion in the study up to 7 months after the end of treatment for men and up to 4 months after the end of treatment for women
* Written informed consent signed by the patient and the investigator (on the day of the pre-inclusion at the latest and before any examination required by the study) (article L1122-1-1 Public Health Code)
* Patients with Health insurance (Sécurité Sociale or Couverture Médicale Universelle)
Exclusion Criteria:
* Child B or C cirrhosis (or Child A patients with history of Child B)
* Patients with documented presence of RAVs conferring resistance to sofosbuvir
* Positive HBs Antigen
* Confirmed HIV-1 or HIV-2 infection
* Pregnant or breast-feeding women or men whose female partners are pregnant
* Transplant recipients
* Any evolutive ongoing malignant disease, including hepatoc…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

rate of the Sustained Virological Response 12 weeks after the end of the therapy (SVR12), i.e. at W28 or W36 for treatment duration of 16 weeks and 24 weeks respectively.
