Praxis Precision Medicines to Present on Ulixacaltamide at the American Academy of Neurology 2024 Annual Meeting

April 12, 2024 at 8:00 AM EDT

Innovative design of ongoing Phase 3 clinical program expected to set precedent for future clinical trials in essential tremor

BOSTON, April 12, 2024 (GLOBE NEWSWIRE) -- Praxis Precision Medicines, Inc. (NASDAQ: PRAX), a clinical-stage biopharmaceutical company translating genetic insights into the development of therapies for central nervous system (CNS) disorders characterized by neuronal excitation-inhibition imbalance, today announced that it will deliver presentations of two abstracts showcasing progress of its clinical program evaluating ulixacaltamide for adults with essential tremor (ET) at the American Academy of Neurology (AAN) 2024 Annual Meeting taking place in Denver, Colorado, April 13 – 18, 2024.

“With Essential3, we’ve developed a decentralized trial program unlike any other in ET, and among the first in the industry,” said Marcio Souza, president and chief executive officer of Praxis. “The experiences of patients with ET are often overlooked so we designed a trial that removes typical obstacles to participation and concentrates on endpoints that truly matter. In our earlier Phase 2 Essential1 study, we observed that patients who were already on propranolol experienced additional benefits when adding ulixacaltamide. Our findings and learnings to date highlight the promise of ulixacaltamide for those living with ET.”
