Press Releases

CORAL GABLES, Fla., Aug. 01, 2019 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. (Catalyst) (Nasdaq: CPRX), a biopharmaceutical company focused on developing and commercializing innovative therapies for people with rare debilitating, chronic neuromuscular and neurological diseases, today announced its support of Spinal Muscular Atrophy (SMA) Awareness Month. Taking place in August, SMA Awareness Month involves activities worldwide to spotlight the work the SMA community does year-round to raise awareness of the debilitating and potentially deadly disease.

“We are proud to be part of the global movement to raise awareness of SMA and recognize the importance of developing new evidence-based medicines required to improve the lives of patients, families and caregivers afflicted with SMA,” said Patrick J. McEnany, Chairman and CEO of Catalyst.

“We are pleased to be leading the Catalyst sponsored pilot study of Firdapse® as a possible treatment option for SMA Type 3,” stated Dr. Lorenzo Maggi at the Carlo Besta Neurological Institute in Milan, Italy. “Defects in the neuromuscular junction appear to be concomitant to degeneration of motor neurons. The literature suggests that amifampridine may have clinical utility in these patients through its action on the impaired neuromuscular junction transmission.”

Out of every 10,000 births, one baby is born with SMA. SMA is a genetic disease that affects the part of the nervous system that controls voluntary muscle movement. It is caused by malfunctioning genes that affect how nerve cells and muscle cells communicate across the neuromuscular junction—the place where nerve cells meet muscle cells. Patients with SMA can have severe muscle weakness in the upper arms, legs, and shoulders. In some instances, SMA may lead to paralysis or death.
