A Phase 4 interventional study of sofosbubir/velpatasvir and sofosbubir/velpatasvir/voxilaprevir in Hepatitis C, Chronic, sponsored by Partners in Health. Status unknown at 1 site in Rwanda. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2019-09-11.
Sponsored by Partners in Health · Phase 4, Interventional, and Treatment
The main purpose of the study is to determine the antiviral efficacy and evaluate the safety and tolerability of sofosbuvir/ velpatasvir (SOF/VEL) and sofosbuvir/ velpatasvir/ voxilaprevir (SOF/VEL/VOX) used to treat individuals with chronic hepatitis C virus infection in Rwanda adults.
This is an open-label single-arm study that will examine the antiviral efficacy, safety and tolerability of 12 weeks daily therapy with fixed dose combination (FDC) of SOF/VEL and SOF/VEL/VOX administered respectively in HCV-infected treatment-naïve adult participants and in HCV-infected individuals with a history of virologic failure to SOF/LDV or other DAA-containing regimen. A total of 100 participants will be enrolled in this portion of the SHARED study, labelled the "SHARED 3 study": 60 treatment-naïve participants and 40 individuals with history of virologic failure to SOF/LDV or other DAA-containing regimen
950 studies on the registry are indexed under Hepatitis C, Chronic; 8 are open to participants now.
This study's planned enrollment of 100 is above the median of 90 across 696 interventional studies indexed under Hepatitis C, Chronic.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
