September 23, 2024 - $Biohaven (BHVN.US)$ rises 18.92% to $48.030 on Monday. The company achieves positive topline results in pivotal study of troriluzole in SCA.

What Happened?

Biohaven Ltd. today announced positive topline results from pivotal Study BHV4157-206-RWE (NCT06529146) 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 (Figure 1). SCA is a rare, progressively debilitating neurodegenerative disease that affects approximately 15,000 people in the United States and 24,000 in Europe and the United Kingdom. There are no FDA approved treatments for SCA.

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 (OR) of 4.1 (95% CI: 2.1, 8.1) for the untreated external control arm versus troriluzole treated subjects (p < 0.0001; pooled analysis).

Statements by Relevant Practitioners

Dr. Susan Perlman, Director of Ataxia Clinic and Neurogenetics Clinical Trials at the David Geffen School of Medicine at UCLA stated, "SCA is a debilitating, relentlessly progressive disease that destroys quality of life, leaving patients unable to care for themselves, walk, or speak. Troriluzole is the very first treatment to show a delay in disease progression that can give patients additional years of independence, where they can walk without assistance, continue to work, play with their children, and participate in daily activities. This is an exciting and hopeful moment for the SCA community."
