CORAL GABLES, Fla., Aug. 09, 2023 (GLOBE NEWSWIRE) — Catalyst Pharmaceuticals, Inc. (“Catalyst” or “the Company”) (Nasdaq: CPRX) today reported financial results for the second quarter of 2023 and provided a corporate update.

“We are extremely pleased with the remarkable progress we achieved during the first half of 2023, fueled by the sustained and exceptional organic growth of FIRDAPSE, a significant contributor to our revenue accomplishments. Moreover, our sales of FYCOMPA, which we acquired at the end of January 2023, have bolstered our success for the first half of 2023, and we have recently completed our integration of the FYCOMPA team and believe that FYCOMPA will be a synergistic and meaningful contributor to our future revenue potential,” stated Patrick J. McEnany, Chairman and CEO of Catalyst. “Our most recent acquisition, which we closed in July, is the North American license for vamorolone, a late-stage asset with a PDUFA action date of October 26th, 2023, for the treatment of Duchenne muscular dystrophy. Assuming approval, this product is expected to further strengthen our neuromuscular product portfolio. Results achieved from these significant accomplishments have established a robust foundation to advance our strategic initiatives and reinforce the durability of our near and long-term growth potential. We look forward to achieving numerous important milestones in the second half of this year to further build an even more vital business.”
