RNAi outfit Corsera will use the raise to support its first clinical trial, a phase 1 study of PCSK9-targeting siRNA COR-1004 that just began dosing patients. The company’s lead cardiovascular program also includes COR-2003, which is designed to target angiotensinogen and is set to enter a clinical trial of its own in mid-2026.
