Bioprojet and Endo Jointly Announce Agreement for Paladin Labs Inc. to Commercialize Pitolisant in Canada

July 25, 2018

DUBLIN, July 25, 2018 /PRNewswire/ -- Endo International plc (NASDAQ: ENDP), announced today that its subsidiary Endo Ventures Limited has entered into definitive agreements with Bioprojet SCR to register, commercialize, and distribute pitolisant on an exclusive basis in Canada.  Paladin Labs Inc., an operating company of Endo, will be commercializing pitolisant in Canada.

Pitolisant is a selective histamine H3-receptor antagonist/inverse agonist that enhances the activity of histaminergic neurons. The drug is approved in the European Union (EU) for the treatment of narcolepsy in adult patients with or without cataplexy and is distributed under the tradename WAKIX®, but is not approved in Canada.  Pitolisant has an orphan designation in the EU and the US for the treatment of narcolepsy.   

Narcolepsy is a serious, chronic disorder characterized by excessive daytime sleepiness (EDS), with some patients experiencing intermittent uncontrolled muscle weakness or paralysis (cataplexy). Pitolisant increases the release of the brain chemical histamine to increase a patient's wakefulness and alertness. The novel drug was developed after decades of research by Bioprojet co-founders Dr. Jeanne-Marie Lecomte and Prof. Jean-Charles Schwartz

In accordance with the terms of the agreements, Paladin will be responsible for the registration distribution, sales, marketing, medical affairs, pricing and reimbursement activities in connection with pitolisant while Bioprojet will be responsible for supplying the drug to Paladin.

"Bioprojet is proud to partner with Endo and its affiliate, Paladin, which has more than a 20 year successful track record of commercializing innovative, much-needed specialty products in Canada. We believe this partnership will be expertly led by Paladin, bringing relief to patients suffering from this debilitating disease," said Prof. Schwartz.

"We are very pleased to work with Bioprojet to bring a new treatment option for Canadian narcolepsy patients," said Rahul Garella, Senior Vice President, International Pharmaceuticals of Endo.  "This product complements Paladin's promoted specialty products portfolio and provides us with an additional pillar upon which to grow our portfolio of innovative treatments."
