Sofosbuvir Plus Daclatasvir With or Without Ribavirin and Chronic HCV Genotype (GT) 4

Phase 2
Completed
Conditions
Chronic Hepatitis C Virus Infection
Interventions
Drug: (SOF and DCV)
Drug: (SOF, DCV, and RBV)
Registration Number
NCT04387526
Lead Sponsor
Beni-Suef University
Brief Summary

This study aims to evaluate the efficacy and safety of DCV plus sofosbuvir (SOF) with or without ribavirin (RBV) for treatment of Egyptian participants infected with HCV GT4.

Detailed Description

Egyptian participants infected with HCV GT4 were classified into two groups: group 1 (easy to treat) was treated with a dual therapy of SOF/DCV daily for 12 weeks and group 2 (difficult to treat) was treated with a triple therapy of SOF/DCV/RBV daily for 12 weeks.

SOF dose was 400 mg/day given orally DCV was given in a dose of 60 mg/day, orally. RBV was given as oral tablets in the morning and in the evening based on patient's weight and tolerability (starting dose 600 mg/day to reach 1200 mg/day.

Arm && Interventions
GroupInterventionDescription
SOF/DCV(SOF and DCV)Easy to treat arm: Participants were treated with a dual therapy (SOF and DCV) for 12 weeks. This arm included non-cirrhotic treatment-naïve patients
SOF/DCV/RBV + Cirrhosis(SOF, DCV, and RBV)This difficult-to-treat arm included 111 cirrhotic participants who were treated with a triple therapy (SOF, DCV, and RBV) for 12 weeks.
SOF/DCV/RBV + Non-Cirrhosis(SOF, DCV, and RBV)This difficult-to-treat arm included treatment-experienced non-cirrhotic participants (77 participants) who were treated with a triple therapy (SOF, DCV, and RBV) for 12 weeks.
Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) in Each Treatment Arm SVR1212 weeks after last dose

SVR12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) level \< 15 IU/m 12 weeks after the last dose of drugs.

Number of Participants With Adverse Events in Each Treatment Armup for 12 weeks after planned End of Treatment (EOT).

An adverse event (AE) is defined as any untoward medical occurrence in a participant clinical investigation after administering a pharmaceutical drugs

Serious adverse event (SAE) is an event that results in death, life-threatening, requires hospitalization, or significant disability/incapacity

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Viral relapse12 weeks after last dose

Viral relapse was HCV RNA level ≤ 15 IU/ml at EOT, but detectable HCV RNA level \> 15 IU/ml 12 weeks after planned EOT.

Percentage of Participants With On-treatment Virologic Failureup tp 24 weeks

On-treatment virologic failure was defined as quantifiable HCV RNA throughout the entire treatment period with HCV RNA greater than 15 IU/ml
