SHANGHAI and BOSTON, March 22, 2021 /PRNewswire/ -- Citrine Medicine, a China-based rare disease therapeutics company, today announced that it has received a clinical trial waiver from the National Medical Products Administration (NMPA) in China for Wakix® (pitolisant), a narcolepsy drug approved in the European Union and the United States for the treatment of narcolepsy in adult patients with and without cataplexy. The company also announced, during a ceremony that took place during Sleep Awareness Week, that its holding company the RareStone Group has signed a five-year strategic partnership with the Chinese Alliance for Rare Diseases (CARD), a non-profit organization promoting the development of rare disease therapies and treatment access in China.
Together, these efforts support Citrine's efforts to build the first rare disease ecosystem in China. The clinical trial waiver enables Citrine to accelerate its efforts to bring Wakix to patients in need. Wakix 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. The clinical trial waiver enables Citrine to submit a New Drug Application (NDA) using data from the U.S. and Europe.
As part of the strategic partnership, Citrine will work closely with CARD to promote advances in rare disease prevention, diagnosis, and treatment. The partnership will include rare disease research collaborations; the establishment of a patient registry; rare disease education projects and collaborations; the establishment of rare disease expert panels; and the launch of rare disease-focused conferences in China.
"Together, the clinical trial waiver for Wakix and our new partnership with CARD represent a significant step forward in our efforts to build Citrine into a leading rare disease platform company in China," said Melissa Bradford-Klug, Citrine's chief business officer and U.S. president. "The clinical trial waiver will vastly increase the speed at which we can bring Wakix to patients with narcolepsy, and provides important validation of our business model and our platform. We founded Citrine to build a rare disease ecosystem in China and bring much-needed drugs to patients affected by rare and orphan diseases. We thank our founding investors, F-Prime Capital, Vivo, and Eight Roads, for their continued support of our business model and platform, and look forward to working with the NMPA, as well as with physicians, patients, and families affected by narcolepsy, to bring Wakix and other important rare and orphan disease therapies to the Chinese market."
"We are incredibly impressed by the speed that Citrine is moving towards bringing Wakix to patients," said Dandan Dong, Ph.D., a managing director at Vivo Capital and member of Citrine's Board of Investors. "After closing their Series A financing round late last year, the Citrine team is making incredible progress in their efforts to build a rare disease ecosystem to benefit patients and families in China."
