Item 8.01

Other Events.

On June 12, 2019, the Company announced that it has filed a suit against the U.S. Food and Drug Administration (FDA) and several related parties challenging the recent approval of a new drug application and related drug labeling for Jacobus Pharmaceutical Company’s drug Ruzurgi^™ for the treatment of Lambert-Eaton Myasthenic Syndrome in pediatric patients. The complaint was filed on June 12, 2019 in the United States District Court for the Southern District of Florida.

The complaint alleges that the defendants’ approval of Ruzurgi violated multiple provisions of FDA regulations regarding labeling, resulting in misbranding in violation of the Federal Food, Drug, and Cosmetic Act (FDCA); violated Catalyst’s statutory rights to Orphan Drug Exclusivity and to New Chemical Entity Exclusivity under the FDCA; and was in multiple other respects arbitrary, capricious, and contrary to law, in violation of the Administrative Procedure Act. Among other remedies, the suit seeks an order vacating the FDA’s approval of Ruzurgi.

A copy of a press release issued by the Company announcing the filing of the lawsuit is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
