Catalyst Pharma Files Lawsuit Against FDA Approval of Ruzurgi

Read MoreHide Full Article

Catalyst Pharmaceuticals, Inc. (CPRX - Free Report) has filed a suit against the FDA and several related parties, challenging the recent approval of Jacobus Pharmaceutical Co's drug, Ruzurgi, for the treatment of Lambert-Eaton Myasthenic Syndrome (LEMS) in pediatric patients. 

According to the lawsuit, the approval of Ruzurgi, in May 2019, violated provisions of the FDA regulations regarding labeling, resulting in misbranding in violation of the Federal Food, Drug, and Cosmetic Act (FDCA). The lawsuit also alleges that the approval also violated Catalyst's rights to exclusivity for its drug, Firdapse. Among other remedies, the suit seeks an order vacating the FDA's approval of Ruzurgi.

Firdapse was approved by the FDA in November 2018 for the treatment of LEMS in adults. The drug was launched in the United States in January 2019.

Shares of Catalyst have surged 91.2% compared with the industry’s growth of 6.2%.

 

The company is also working on developing Firdapse for additional indications. Catalyst initiated an investigator-sponsored phase II/III study on the drugfor the symptomatic treatment of MuSK-antibody positive myasthenia gravis (MG) in February 2016. In April 2018, the company enrolled the first patient in its phase III study for the same indication. The company expects to announce top-line results in the second half of 2019.

In October 2015, the company initiated a small-blinded study on Firdapse for the treatment of certain types of congenital myasthenic syndromes (CMS) in the pediatric population (aged 2-17 years). The company expects to report top-line results in the second half of 2019. If the results are successful, the CMS indication will be added to Firdapse’s label.
