By Amit Chowdhry ● May 16, 2025

Sirius Therapeutics has completed nearly $50 million in Series B2 financing to advance clinical development of the company’s novel siRNA therapeutics for cardiometabolic disorders and continue innovation of its RNA delivery technologies. A renowned corporate venture capital firm led the financing round, which was joined by a new investor (BioTrack Capital) and existing investors OrbiMed, Creacion Ventures, and Hankang Capital.

CEO Dr. Qunsheng Ji pointed out that the company has three clinical-stage programs and a deep preclinical pipeline. And the most advanced compound, SRSD107, is a long-acting, next-generation anticoagulant for thromboembolic disorders poised to begin Phase 2 clinical development in Europe.

The company also recently applied to the European Medicines Agency (EMA) to initiate a Phase II trial. Sirius has also received approval from the U.S. FDA and the China NMPA and has started Phase 1 studies with SRSD216, a novel siRNA therapeutic for hyperlipoproteinemia in patients with atherosclerotic cardiovascular disease. SRSD101, the company’s siRNA therapeutic for dyslipidemia, is undergoing Phase 1 clinical trials in China.
