Study Endpoints

Primary Endpoints

Percentage of Participants With Sustained Virologic Response (SVR) at Post-Treatment Follow-up Week 24 (SVR24)
24 Weeks after treatment discontinuation (Follow-up Week 24)

SVR was defined as Hepatitis C Virus ribonucleic acid (HCV RNA) \< lower limit of quantitation (LLOQ) target detected (TD) or not detected (TND) at post-treatment follow-up Week 24.

Proportion of genotype 1 subjects with SVR12, defined as HCV RNA < LOQ at post-treatment Week 12, for all subjects infected with HCV genotype 1
At 12 weeks post-treatment
Proportion of treated subjects with SVR12, defined as HCV RNA < LOQ at post treatment Week 12, for subjects who are prior null or partial responders to P/R or are treatment-naive
At 12 weeks post-treatment
SVR12 Rate

12 weeks post-treatment
Phase 2a and Phase 2b: Safety, as measured by the frequency of SAEs and discontinuations due to AEs
12 weeks after first dose
Antiviral activity as determined by proportion of HCV genotype 1 subjects with extended rapid virologic response (eRVR), defined as undetectable HCV RNA
Week 4
Phase 2b only: Antiviral activity, as determined by the proportion of HCV genotype 1 subjects with 24-week sustained virologic response (SVR24), defined as undetectable HCV RNA
at follow-up Week 24
Antiviral activity will be assessed by the magnitude and rate of change in plasma HCV RNA levels from baseline. The primary endpoint for antiviral activity is decrease from baseline in plasma HCV RNA levels to Day 3/ or 5
To assess the change in HCV RNA during dosing with BMS-650032 from baseline to Day 3 and during follow-up period

Frequently asked questions about Asunaprevir

What is asunaprevir used for?

Asunaprevir is an investigational small molecule antiviral studied for the treatment of hepatitis C, including hepatitis C virus genotype 4 infection. It has been evaluated in clinical trials as part of combination regimens for patients with chronic hepatitis C, including those who had previously failed peg-interferon and ribavirin therapy.

Who is developing asunaprevir?

Asunaprevir is being developed by Bristol-Myers Squibb Company, which trades under the ticker BMY. The company has sponsored the clinical trial program evaluating asunaprevir in hepatitis C, including Phase 3 studies such as the Hallmark DUAL trial.

What phase is asunaprevir in?

Asunaprevir has been studied in Phase 3 clinical development. The program includes completed Phase 3 trials such as the Hallmark DUAL study and a Phase III China GT 1b trial, along with earlier-phase studies. Asunaprevir is investigational and has not been approved by the FDA.

What clinical trials is asunaprevir in?

Asunaprevir has been evaluated in completed trials including NCT01581203 (Phase 3 Hallmark DUAL), NCT01995266 (Phase III China GT 1b), NCT02107365 (Phase 2 ANRS HC32 QUATTRO in HCV genotype 4), and NCT01886599 (Phase 1 pharmacokinetics in kidney disease). These trials enrolled a combined total of 1,146 participants.

Is asunaprevir the same as ASV?

Yes, asunaprevir is also known as ASV. ASV is the abbreviated name used for asunaprevir in clinical trial titles and scientific literature, such as the Phase III Hallmark DUAL study listed as ASV+DCV.
