Ombitasvir /Paritaprevir/Ritonavir Plus Ribavirin on HCV GT4

Phase 1
Completed
Conditions
Hepatitis C Virus Infection
Interventions
Drug: OBV/PTV/r) ± ribavirin (RBV)
Registration Number
NCT04378608
Lead Sponsor
Beni-Suef University
Brief Summary

The objective of the investigators was to delineate the efficacy and safety of Ombitasvir, paritaprevir with ritonavir (OBV/PTV/r) plus ribavirin (RBV) on chronic HCV GT4 Egyptian naïve patients

Detailed Description

Direct-acting antivirals (DAAs) combination therapies from various mechanisms of action and families have been revolutionized the management landscape of chronic hepatitis C virus (HCV). Ombitasvir, paritaprevir with ritonavir (OBV/PTV/r) ± ribavirin (RBV) are approved to treat HCV genotype 4 (GT4) infection. Here, investigators' objective was to delineate the efficacy and safety of OBV/PTV/r plus RBV of HCV GT4 in the treatment of Egyptian naïve patients.

Between 5 January and 8 September 2017, a cohort of 100 Egyptian patients infected with HCV GT4 was allocated and administered orally OBV/PTV/r with RBV, for 12 weeks, which given as oral tablets based on patient tolerability. The primary endpoint of investigators' study was a sustained virological response (HCV RNA \< 12 IU/mL) 12 weeks from the cessation of the treatment (SVR12).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)12 weeks after last dose

SVR12 was defined as hepatitis C virus ribonucleic acid (HCV RNA) level less than 12 IU/mL 12 weeks after the last dose of study drug.

adverse event (AE)Screening up to 30 days after last dose

An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation observed after administering a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A serious adverse event (SAE) is an event that results in, death, participant hospitalization, life-threatening, significant disability/incapacity, or a congenital anomaly.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Post-treatment Relapse Within 12 Weeks Following End of TreatmentUp to 12 weeks after last dose

Post-treatment relapse was defined as defined as confirmed HCV RNA \> 12 IU/ml between the end of treatment and 12 weeks after the last dose of study drug among participants who completed treatment with HCV RNA \< 12 IU/ml at the end of treatment.
