Frequently asked questions about Tegobuvir

What is Tegobuvir used for?

Tegobuvir was studied for the treatment of chronic hepatitis C, specifically genotype 1 infection, in previously untreated patients. It was evaluated as part of a combination regimen rather than as a standalone therapy. Tegobuvir is an investigational small molecule and is not an approved treatment.

Who makes Tegobuvir?

Tegobuvir was developed by Gilead Sciences, Inc., which trades on the Nasdaq under the ticker GILD. Gilead sponsored the clinical program evaluating the compound in chronic hepatitis C.

What phase is Tegobuvir in?

Tegobuvir reached Phase 2 clinical development. One Phase 2 trial has been completed, and no trials are currently active. The drug remains investigational and has not been approved for any indication.

What clinical trials is Tegobuvir in?

Tegobuvir was evaluated in the completed Phase 2 trial NCT01271790, titled a study of response-guided duration of combination therapy with GS-9451, Pegasys and Copegus with and without Tegobuvir (GS-9190) in previously untreated subjects with genotype 1 chronic hepatitis C. The trial enrolled 245 participants across the United States and several European countries.

Is Tegobuvir the same as GS-9190?

Yes, Tegobuvir is also known as GS-9190, and the capsule formulation is referred to as tegobuvir capsule. These names refer to the same investigational compound developed by Gilead Sciences for chronic hepatitis C.

How was the Tegobuvir Phase 2 trial designed?

The Phase 2 trial NCT01271790 was a randomized, double-blind, placebo-controlled study. It enrolled 245 adults aged 18 years and older with genotype 1 chronic hepatitis C who had not been previously treated, and it evaluated response-guided duration of combination therapy. The trial has been completed.
