Telaprevir-based regimens increase rates of SVR in patients with genotype 1 HCV infection

In continuation of my update on telaprevir-based regimens, I found this article interesting to share with.....

In a clinical trial known as PROVE 3 published in this week's New England Journal of Medicine, treatment with telaprevir-based regimens significantly increased rates of sustained viral response (SVR) in patients with genotype 1 hepatitis C virus (HCV) infection who did not achieve SVR with at least one prior course of pegylated-interferon and ribavirin therapy. In the trial, 51 percent and 53 percent of patients who received telaprevir in combination with pegylated-interferon and ribavirin as part of a 24-week or 48-week regimen, respectively, achieved SVR.   More...

Positive Phase 2 results of Telaprevir...

I did mention about telaprevir (structure) in my earlier blog, and following other developments for hepatitis C (blogs). Now Vertex Pharmaceuticals has announced the results of Phase 2.

The results are really encouraging and as per the claim by the company "more than 80 percent of hepatitis C patients in each arm of the Phase 2 Study C208 achieved a sustained viral response (SVR) with a telaprevir-based regimen according to results of an intent-to-treat (ITT) analysis".

Across the four arms, SVR rates were 82 and 83 percent in patients treated with the every 12 hour telaprevir-based regimen (PEGINTRON and PEGASYS, respectively) and 81 and 85 percent in patients treated with the every 8 hour regimen (PEGINTRON and PEGASYS, respectively). For the majority of patients, these SVR rates were obtained with a 24-week telaprevir-based regimen.
