MYR Pharmaceuticals has announced highly positive results from its MYR 202 clinical trial, a Phase 2b study investigating Bulevirtide in chronic hepatitis delta infection. After 24 weeks of treatment Bulevirtide demonstrated an excellent safety profile with no drug-related serious adverse events during the treatment period of 24 weeks and no treatment discontinuations due to the study medication. The primary endpoint, undetectable HDV RNA or decline of ≥2 log IU/ml HDV RNA to baseline, was met for all doses of Bulevirtide.
