Study summary

This is a study to define strategies for Nephrologists to directly supervise and apply direct acting antivirals to cure hepatitis C in hemodialysis patients. Strategies will include identification of candidate patients, application for insurance approval, specifics of direct acting antiviral therapy (Zepatier with or without ribavirin) and laboratory monitoring during and after therapy.

Read the detailed description

Background - Hepatitis C (HCV) is common in hemodialysis (HD) patients with reported prevalences of 25%, By 2020, predicted 775,000 hemodialysis patients in the US, of whom 109,000 will have HCV. Hepatitis C is associated with increased mortality in HD patients, decreased kidney allograft survival, and a source of nosocomial infection in hemodialysis units. Currently drugs to cure HCV - direct acting antivirals (DAA) which can be safely given to HD patients are now available. A significant portion of the medical care provided to HD patients is by Nephrologists and HD staff.

Goals of Protocol - 1. Provide guidelines for implementation and monitoring of DAA therapy in HD patients with HCV 2. Provide Nephrologists strategies for identification of candidate HD patients, obtainment of third party approval for DAA payment, specific drug dosing protocols based on genome type of HCV, and laboratory and clinical monitoring during DDA therapy. 3, By reducing the pool of HCV patients in a HD Unit, the risk of nosocomial transmission of HCV t o other patients and staff will be reduced

Study Design - an interventional, prospective, non-randomized, non-blinded trial to evaluate real world strategies to identify and treat HCV infected patients with Zepatier

Study Procedures 1. Patients who meet inclusion criteria without exclusion criteria be assigned treatment with Zepatier with or without Ribavirin according to following schedule: (a) Genotype 1a - treatment naive without NS5A polymorphism - Zepatier one tablet (100 mg grazoprevir and 50 mg elbasvir) per day for 12 weeks (b) Genotype 1a - treatment naiive with NS5A polymorphism - Zepatier one tablet daily and ribavirin (200 mg) daily for 16 weeks (c) Genotype 1b-treatment naive - Zepatier one daily for 12 weeks (d) Genotype 1a or 1b - prior treatment with INF or HCV NS3/4A protease inhibitor - Zepatier and ribavirin each once daily for 12 weeks (e) Genotype 4 - treatment naive - Zepatier one daily for 12 weeks (f)Genotype 4 -prior treatment - Zepatier and ribavirin each once per day for 16 weeks

Baseline/Screening Testing: 1. HCV genotype testing 2. HCV viral RNA load 3. Liver function tests 4, Protime, Partial Thromboplastin time 5. HIV - if positive, then determine viral RNA and CD4 and T cell count 6. Liver biopsy (within 24 mo of treatment) or Fibroscan within 12 mo of treatment 7. Hepatitis BsAg 8. For patients with HCV genotype 1a, test fro NS5A mutation

Treatment of HIV/HCV co-infected patients will be done in collaboration with the HIV treating physician to determine if any adjustments in the HIV drug regimen will be required

Testing/Evaluations during Active DAA Treatment - 1. LFT and RNA HCV viral load at week 4, 8, and 12. For patients on 16 weeks of treatment, LFT at week 16 as well 2. For patients on combination Zepatier and ribavirin, hemoglobin monitoring every week during treatment 3. Clinical pharmacology evaluation for compliance and adverse events at week 4,8,and 12 (and week 16 for patients on 16 week treatment)

Testing/Evaluation Post DAA Treament - 1, RNA viral load at 12 weeks post treatment 2. Clinical Pharmacologoy evaluation 12 weeks post treatment for adverse events 3. patients who achieve sustained viral remission at 12 weeks will be identified in HD records as HCV ab positive but HCV viral load RNA negative

Terms in these criteria, in plain language(7)

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.

Hepatitis C tests

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.

Reproductive potential

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

ECG (electrocardiogram)

A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.

Autoimmune disease

A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.

Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.

Results

Posted Dec 15, 2021
Limitations and caveats
We anticipated screening 30 patients and enrolling 25 patients. However, there was a significant delay in the regulatory approvals for the protocol and during this delay period, many of the potential patients ultimately received direct acting antivirals from the primary care physicians or other physicians outside of Nephrology

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Sep 2019 to primary completion in May 2020, 7 months.

Results were first posted in Dec 2021, 1 year 7 months after primary completion.

Of 56 non-industry phase 4 interventional studies under Hepatitis C, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 17 and three quarters within 49. This study's 7 months is below that.

Counting every sponsor, half of 58 studies reached it within 24 months; a quarter within 16 and three quarters within 48.

Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 15, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
