Vertex Pharmaceuticals (MA) Nails Mid-Stage Study for Influenza

Published: Mar 04, 2013

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Vertex Pharmaceuticals Incorporated (Nasdaq: VRTX) today announced that treatment with VX-787 in a Phase 2 influenza challenge study resulted in statistically significant improvements in viral and clinical measurements of infection. VX-787 is an investigational new class of medicine for the treatment of influenza and is designed to directly inhibit replication of the virus. The study met its primary endpoint, and showed a statistically significant decrease in the amount of virus in nasal secretions (viral shedding) over the seven-day study period. In addition, at the highest dosing regimen evaluated in the study, there was a statistically significant reduction in the severity and duration of influenza-like symptoms. People in this dose group experienced influenza-like symptoms for a median of 1.9 days, compared to 3.7 days in the placebo group. In addition, 93 percent of people in this dose group showed no clinical symptoms of influenza after three days of treatment, compared to 41 percent of people in the placebo group. In this study, VX-787 was generally well-tolerated, with no adverse events leading to discontinuation. Based on these data, Vertex will explore collaborative opportunities to support further development of VX-787.
