CORAL GABLES, Fla., March 28, 2024 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. ("Catalyst") (Nasdaq: CPRX), a commercial-stage, patient-centric biopharmaceutical company focused on in-licensing, developing, and commercializing novel high-quality medicines for patients living with rare and difficult-to-treat diseases, today announced its endorsement of the inaugural Lambert-Eaton myasthenic syndrome ("LEMS") Awareness Day. This landmark event, now officially observed annually on March 30th, signifies a meaningful milestone for the LEMS community. The chosen date holds profound historical significance, coinciding with the publication of Dr. Edward Lambert and Dr. Lee Eaton's pioneering research on LEMS, which has greatly advanced the understanding and treatment of this rare neuromuscular disorder.

"Creating an awareness day for LEMS is a huge win for our community," said Price Wooldridge, Founder and Board Member of the LEMS Family Association. "This brings us one step closer to our goal, improving the awareness of our rare condition in the larger population. We couldn't be more thrilled to celebrate the milestone of this first LEMS Awareness Day together."

"In the realm of rare diseases, awareness is the key that unlocks paths to diagnosis and treatment. By shedding light on LEMS, we pave the way for better support, understanding, and care for those who need it most," stated Richard J. Daly, CEO of Catalyst. "At Catalyst, we are proud to stand alongside the LEMS Family Association in honoring this pivotal event. Together, we forge pathways of support and understanding for those affected by rare diseases, illuminating a brighter future for all."

LEMS is a rare neuromuscular disease that affects at least 3,600 and potentially up to 5,400 LEMS patients in the United States. For more information, please visit www.lemsfamily.org and www.lemsaware.com.
