CORAL GABLES, Fla., May 10, 2022 (GLOBE NEWSWIRE) -- Catalyst Pharmaceuticals, Inc. ("Catalyst") (Nasdaq: CPRX), a commercial-stage biopharmaceutical company focused on in-licensing, developing, and commercializing novel medicines for patients living with rare diseases, today reported financial results for the first quarter 2022 and provided a corporate update.

"I am proud of Catalyst’s solid progress in the first quarter of 2022, where we delivered record revenues, driven in part, by new patients converting to FIRDAPSE® following the removal of Ruzurgi® from the U. S. market in February 2022. Our accomplishments exemplify our exceptional commercial and patient services capabilities and steadfast commitment to the LEMS patient community that we serve," said Patrick J. McEnany, Chairman and Chief Executive Officer of Catalyst. "We also achieved several meaningful milestones during the quarter, including the issuance of three new patents that we believe position us to deliver sustainable long-term growth for FIRDAPSE. We anticipate this to be a transformative year for Catalyst, as we work with increased momentum to diversify and invest in innovative therapeutic opportunities for rare diseases. We approach these objectives from a position of strength and look forward to enhancing our growth potential near-term, as well as adding long-term value for all of our stakeholders."
