Catalyst (CPRX) Settles Patent Dispute Over Sole Marketed Drug

Read MoreHide Full Article

Catalyst Pharmaceuticals (CPRX - Free Report) has reached a settlement with Jacobus Pharmaceutical Company, Inc. and PANTHERx Rare LLC, with regard to the ongoing patent infringement litigation over its sole-marketed drug, Firdapse (amifampridine), which is approved to treat Lambert-Eaton Myasthenic Syndrome (“LEMS”) in adult patients.

The settlement of this litigation marks the end of an ongoing dispute between Catalyst Pharmaceuticals and Jacobus ever since the FDA approved the latter’s drug, Ruzurgi (amifampridine), in 2019, for treating LEMS in pediatric patients. This was contested by CPRX in its lawsuit, which claimed that the regulatory body’s approval violated the orphan drug designation granted to Firdapse for the treatment of LEMS.

Per the terms of the settlement, CPRX will stop pursuing all claims related to patent litigation between the companies. In addition, Catalyst Pharmaceuticals will acquire certain intellectual property (IP) rights belonging to Jacobus, including the rights to develop and commercialize Ruzurgi in the United States and Mexico.

In return, CPRX will make an undisclosed cash payment to Jacobus, with the latter also being eligible to receive low single-digit royalties on net U.S. sales of amifampridine.

Following the settlement, Jacobus will dismiss its pending petition before the U.S. Supreme Court seeking to overturn the Appeal Court’s decision.

Shares of Catalyst Pharmaceuticals have risen 14.3% in the past year against the industry’s 20.7% decline.

CPRX achieved a major milestone last September, when it received a positive decision from the U.S. Appeals Court. The positive decision supported the orphan drug designation for Firdapse, granted by the FDA for LEMS. The Appeals Court has also denied Jacobus’ petition for rehearing its ruling and issued a mandate to the District Court to grant summary judgment in Catalyst’s favor. The District Court granted summary judgment this February, making the FDA’s approval to Ruzurgi in LEMS invalid.

Firdapse is the first and currently the only approved drug in Catalyst Pharmaceuticals’ portfolio. In fact, the drug is currently the only approved treatment for LEMS in adults in the United States. The company has multiple patents for Firdapse issued in the United States that strengthen the drug’s commercial durability through 2034.
