SVR12 Rate
Week 36

HCV RNA measured 12 weeks after the end of the HCV treatment (Week 36)

AUC(TAU) of Asunaprevir assessed using plasma concentrations on Day 7

Frequently asked questions about Asunaprevir

What is Asunaprevir used for?

Asunaprevir is an investigational small molecule being developed for the treatment of Hepatitis C Virus (HCV) infection, including Hepatitis C Virus Genotype 4 Infection. It is intended for use in patients with chronic HCV infection.

Who makes Asunaprevir?

Asunaprevir is being developed by Bristol-Myers Squibb Company, which trades under the ticker symbol BMY. The company has conducted clinical trials of Asunaprevir in multiple countries for the treatment of Hepatitis C Virus infection.

What phase is Asunaprevir in?

Asunaprevir has completed Phase 3 clinical trials for the treatment of Hepatitis C Virus infection. It is an investigational drug and has not been reported as approved by regulatory authorities. The Phase 3 trials were part of the Hallmark program.

What clinical trials is Asunaprevir in?

Asunaprevir has completed two Phase 3 trials: NCT01573351 (Hallmark QUAD, combining Asunaprevir with daclatasvir, peginterferon, and ribavirin) and NCT01581203 (Hallmark DUAL, combining Asunaprevir with daclatasvir). Both trials enrolled patients with Hepatitis C Virus who were null or partial responders, or intolerant/ineligible to prior therapy.

How does Asunaprevir work?

Asunaprevir is a small molecule that targets the Hepatitis C Virus. It is designed to inhibit viral replication by interfering with the NS3/4A protease enzyme, which is essential for the virus to replicate. This mechanism helps reduce the viral load in infected patients.

Is Asunaprevir the same as daclatasvir?

No, Asunaprevir is not the same as daclatasvir. Asunaprevir is an NS3/4A protease inhibitor, while daclatasvir is an NS5A inhibitor. In clinical trials, they have been studied in combination for the treatment of Hepatitis C Virus infection.
