Catalyst Pharmaceuticals Comments on Recent Decision by Health Canada to Re-issue an NOC for ...

June 28, 2021 GMT

CORAL GABLES, Fla., June 28, 2021 (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 commented on the recent decision by Health Canada to re-issue a Notice of Compliance (“NOC”) for Ruzurgi® (amifampridine tablets), once again allowing the product to be marketed in Canada for patients with Lambert-Eaton Myasthenic Syndrome (LEMS). Health Canada’s original NOC for Ruzurgi® for marketing in Canada was quashed in a recent decision of the Federal Court of Canada, which sent the matter back to Health Canada to re-determine its decision to grant marketing authority to Ruzurgi® despite Firdapse’s® data protection rights under Canadian law.

Patrick J. McEnany, Catalyst’s Chairman and CEO commented: “We are obviously disappointed with Health Canada’s decision to re-issue an NOC for Ruzurgi®. Our effort to get Firdapse® approved in Canada commenced three years ago, at a time when there was no approved therapy in Canada to treat LEMS patients. Our interest was to assure that all adult LEMS patients had access to a Health Canada approved therapy, despite recognizing that our market opportunity in Canada was always expected to be small.”

Catalyst and its Canadian sublicensee, KYE Pharmaceuticals (“KYE”), are currently evaluating their further litigation options to challenge Health Canada’s most recent decision, since such decision means that the data protection that Catalyst and KYE are entitled to under Canadian law has not been recognized by Health Canada.
