Tenacia Biopharmaceuticals and Golden Age Health Partner to Commercialize ZTALMY® for CDKL5 Deficiency Disorder in Mainland China

First-ever approved treatment for CDD in China now set for commercial launch through dedicated rare disease platform

 Tenacia Biopharmaceuticals (Shanghai) Co., Ltd. ("Tenacia") and GOLDEN AGE HEALTH (SHANGHAI) CO., LTD., a subsidiary of Golden Age Health Pte. Ltd. (collectively, "GAH") today announced a Commercialization Agreement granting GAH exclusive rights to commercialize ZTALMY® (泽元安), the first and as of now only approved treatment for CDKL5 deficiency disorder (CDD) in Mainland China.

ZTALMY® (ganaxolone oral suspension) was developed by Marinus and Tenacia obtains exclusive rights to develop and commercialize it in Greater China. In July 2024, the drug was approved by the National Medical Products Administration for treatment of seizures associated with cyclin-dependent kinase-like 5 (CDKL5) deficiency disorder (CDD) in patients 2 years of age and older.

Tenacia has partnered with GAH to leverage its comprehensive patient-focused commercialization platform—encompassing disease awareness, diagnosis support, market access, and patient affordability programs—to ensure this therapy reaches the families affected by this devastating rare epilepsy.

"Bringing the first approved therapy for CDKL5 deficiency disorder to patients in China represents exactly the type of mission-critical work Golden Age Health was built for," said Chao (Brook) Wu, Chief Executive Officer of Golden Age Health (Shanghai). "We are honored to partner with Tenacia to ensure that children and families affected by CDD can access this breakthrough treatment as quickly as possible."

Dr. Xiaoxiang Chen, Founder and CEO of Tenacia Biopharmaceuticals (Shanghai), said: "GAH's proven expertise in rare disease commercialization and their commitment to patient access make them the ideal partner to bring ZTALMY® to the patients who need it most in China. Together, we will work to maximize the impact of this important therapy."
