Catalyst Pharmaceuticals Teams Up with Patients and Advocacy Groups to Ring Nasdaq Opening Bell on Rare Disease Day 2022

Ceremony Recognizes Importance of Biopharma Industry and Advocacy Group Collaboration to Address Needs for New Treatments in Orphan and Rare Disorders

Together, Will Ring the Nasdaq Opening Bell to Kick-Off Rare Disease Day on February 28, 2022

CORAL GABLES, Fla., Feb. 24, 2022 (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 diseases, today announced that the company is standing with the National Organization for Rare Disorders (NORD), Global Genes, Muscular Dystrophy Association, Myasthenia Gravis Foundation of America, Conquer MG, and Myasthenia Gravis Association, to ring the opening bell of the Nasdaq market on international Rare Disease Day, February 28, 2022. Organized by Catalyst, the ceremony is part of the ongoing efforts of the biopharma industry and patient advocacy groups to call attention to the need for collaboration to encourage research and development of orphan drugs and bring new treatments to market for rare diseases that affect small patient populations.

“Rare Disease Day and events such as this help individuals and families living with rare diseases know that they are not alone and that there is a community raising awareness on their behalf. NORD is grateful for this opportunity to champion health equity for the rare disease community and help shine a light on their unique experiences and challenges,” said Lisa Sarfaty, Vice President of Community Engagement for the National Organization for Rare Disorders.

“Rare Disease Day is an opportune moment to build awareness, consider our progress, and rally around what has yet to be done. Until the day rare disease becomes a global health priority, we must be relentlessly nimble, creative, resourceful, and collaborative in our efforts to improve the lives and care of the nearly one in 10 Americans and 400 million people worldwide living with rare conditions,” added Craig Martin, CEO of Global Genes.

There are approximately 7,000 identified rare diseases affecting millions across the globe, including 30 million Americans. Only about 5% of the known rare diseases have approved treatments. The biopharmaceutical industry has made great progress, with more than 770 FDA-approved medicines since the enactment of the Orphan Drug Act in 1983. However, there is still much more work to be done. Partnering and collaborating with advocacy leaders and organizations will raise awareness and connect patients with appropriate providers.

“We are committed to making a meaningful impact on the lives of those living with rare diseases,” said Patrick J. McEnany, Chairman and CEO of Catalyst Pharmaceuticals. “Catalyst is working tirelessly with patients living with the rare condition Lambert-Eaton myasthenic syndrome (LEMS), helping them gain access to treatment. We thank our advocacy partners who are standing with us, echoing our relentless commitment to this cause. We are grateful to Nasdaq for the opening bell-ringing opportunity, allowing us to show our support for the rare disease community.”

The ceremony will begin at approximately 9:15 am ET and can be viewed on the Nasdaq live stream at: https://livestream.com/accounts/27896496/events/10011861. A replay of the ceremony will be available at a later date on the Company website at www.catalystpharma.com.
