In the appeal, the 11th Circuit Court of Appeals has overturned the District Court decision to uphold the FDA approval of Ruzurgi for children with Lambert-Eaton myasthenic syndrome (LEMS) despite Orphan Drug status held by Catalyst (CPRX) for Firdapse (amifampridine) 10 mg tablets.

“The Court's decision adopted Catalyst’s core argument that the FDA’s approval of Ruzurgi® violated Catalyst's rights to Orphan Drug Exclusivity,” Catalyst (CPRX) said in a press release.
