About this study
Official title: Sustained Viral Response Rate in 100 Subjects With Cirrhosis Due to Hepatitis C Treated With 12 Weeks of Sofosbuvir, Daclatasvir and Ribavirin
The investigators will treat 100 patients with cirrhosis due to hepatitis C with sofosbuvir 400 mg daily, daclatasvir 60 mg daily and weight-based ribavirin (1000 mg/d if <75 kg, 1200 mg/d if >75 kg, divided in two daily doses) for 12 weeks and calculate the sustained viral response rate at 12 weeks.
Read the detailed description
Cirrhosis due to Hepatitis C presents a rather difficult treatment problem as many cannot tolerate interferon, the previous standard of treatment. The new direct acting antivirals have provided these patients with a new hope. One such combination is sofosbuvir (SOF) 400 mg and daclatasvir (DCV) 60 mg given once daily with or without weight-based ribavirin (RBV) for 12 or 24 weeks. The current recommendation for cirrhotics is SOF/DCV/RBV for 24 weeks but that recommendation is based on the lack of data for shorter periods. In order to evaluate the response rate to the combination of SOF/DCV/RBV the investigators decided to treat 100 HCV cirrhotics with this combination for 12 weeks. Subjects include genotype 1 and 3 patients, the prevalent genotypes in Iran. Patients with Model for End stage Liver Disease (MELD) > 20 are excluded. The investigators will calculate the sustained viral response rate at 12 weeks (SVR12).

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Sofosbuvir, Daclatasvir and Ribavirin in people with Hepatitis C and Cirrhosis, run by Tehran University of Medical Sciences at 1 site in Iran.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Iran. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The sustained viral response rate (time frame: week 24 (12 weeks after end of treatment)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2023.
