Citrine Medicine Announces Approval of Wakix®(pitolisant) for Named Patient Program in China

The narcolepsy drug Wakix can now be prescribed to patients in China with urgent unmet medical needs
 
BOSTON, Mass., and Boao, Hainan, China, May 07, 2021 – Citrine Medicine, a China-based rare disease therapeutics company, today announced that the narcolepsy therapy Wakix® (pitolisant) has been approved by the Health Commission and Medical Products Administration of Hainan Province for its Named Patient Program (NPP). Through this program, patients can be prescribed Wakix® in the Boao Lecheng International Medical Tourism Pilot Zone in Hainan Province.
 
Under the NPP, patients in Boao Pilot Zone with urgent clinical needs can make individual requests, via a special approval procedure, for access to drugs approved in the United States (U.S.), Europe, and other parts of the world but not yet approved by the Chinese National Medical Products Administration (NMPA). Patients may be able to take Wakix® outside of Boao for personal use if approved in advance by the Hainan NMPA.
 
“We are very excited to be able to offer Wakix® to patients with narcolepsy in China via the Named Patient Program only a few months after we obtained the China rights to this therapy,” said Melissa Bradford-Klug, President and Chief Business Officer of Citrine Medicine, Inc. “This is a remarkable milestone, because Wakix® now becomes one of the very few rare disease drugs accessible to Chinese patients via the NPP, significantly expanding access to eligible patients. Our mission at Citrine is to build a rare disease ecosystem in China, and one of the ways we are doing this is by bringing much-needed, clinically-validated rare disease drugs to patients with high unmet medical needs. We look forward to continuing to work with our partners and with China’s regulatory agencies to find expedited pathways to the treatment of rare disease.”
 
Through a partnership with Bioprojet, Citrine has exclusive rights for the commercialization and development of Wakix® in China. The partnership deal was announced in Q4, 2020. Speaking of the partnership, Chong Xu, Ph.D., Principal at F-Prime Capital and Citrine Medicine Board Member, said, “F-Prime has long been committed to investing in companies making a difference in the lives of individuals with rare diseases and their families, and we are pleased to see Citrine make Wakix® available to Chinese patients.”
 
Wakix® is a selective histamine H3-receptor antagonist/inverse agonist that enhances the activity of histaminergic neurons and increases the release of the brain chemical histamine to increase a patient's wakefulness and alertness. It is approved by the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) to treat adults suffering from narcolepsy, a serious, chronic disorder characterized by excessive daytime sleepiness (EDS), with or without cataplexy.
