Based on net product sales in Greater China, LIB will also receive royalty payments.

Hasten will oversee the clinical development, regulatory and marketing activities of lerodalcibep in Greater China. 

The company also plans to file an investigational new drug application with the China National Medical Products Administration at the end of this year. 

Hasten will subsequently commence Phase III clinical trials of lerodalcibep to treat hypercholesterolemia patients in Greater China.

LIB Therapeutics chief operating and chief scientific officer Evan Stein said: “We believe that Hasten, and their experienced, knowledgeable and motivated team of pharma professionals, is the optimal partner to bring our third-generation PCSK9 inhibitor, lerodalcibep, to the large and growing Chinese population with very-high and high risk for CVD, who need substantial additional LDL-cholesterol reductions, despite statin therapy.”
