Biohaven achieves topline results from study of troriluzole

Biohaven announced positive topline results from pivotal Study BHV4157-206-RWE demonstrating the efficacy of troriluzole on the mean change from baseline in the f-SARA after 3 years of treatment. The study achieved the primary endpoint and showed statistically significant improvements on the f-SARA at years 1 and 2. Collectively, data across multiple analyses demonstrate a robust and clinically meaningful slowing of disease progression in SCA patients. These treatment benefits translate into a 50-70% slower rate of decline compared to untreated patients, representing 1.5-2.2 years delay in disease progression over the 3-year study period. Additionally, in a responder sensitivity analysis, disease progression when defined by a 2 point or greater worsening on the f-SARA at 3 years showed an odds ratio of 4.1 for the untreated external control arm versus troriluzole treated subjects
