NCT ID NCT01753557

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This completed Phase 3 trial tested an experimental drug called MP-424, combined with two standard hepatitis C medications (pegylated interferon and ribavirin), in 54 adults with genotype 1 hepatitis C. Participants were either new to treatment or had relapsed after previous therapy. The main goal was to see if the virus stayed undetectable 24 weeks after treatment ended (sustained viral response).

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

MP-424 (an experimental antiviral drug) combined with pegylated interferon alfa-2a and ribavirin

What this could lead to

If successful, this combination could offer a new treatment option for people with genotype 1 hepatitis C who have not been treated before or who relapsed after prior therapy.

What could go wrong

This is a small, completed Phase 3 trial with only 54 participants, so results may not apply to everyone. The regimen includes interferon, which can cause significant side effects like flu-like symptoms and depression.
