Shares of Rapport Therapeutics surged after the company said a trial of its seizure treatment met its primary endpoint.
The stock more than doubled in premarket trading to $35.20.
The Boston company on Monday said its treatment was well tolerated in the 30-patient phase 2a trial and resulted in a statistically significant reduction in long episodes--the trial's primary endpoint--in patients with drug-resistant focal onset seizures. Rapport also said it recorded a 78% reduction in clinical seizures.
The company said it plans to hold a meeting with the Food and Drug Administration in the fourth quarter and to begin pivotal trials in the third quarter of next year.
