(BUSINESS WIRE)--Enzon Pharmaceuticals, Inc. (Nasdaq: ENZN) today announced the Investigational New Drug (IND) approval by the US Food and Drug Administration (FDA) and plan to commence enrollment into a Phase 1a/1b study shortly. The study will evaluate the safety and tolerability of EZN-4176, the company’s novel androgen receptor (AR) mRNA antagonist, for the treatment of patients with castration-resistant prostate cancer (CRPC). Unlike other novel agents for CRPC that inhibits androgen production or receptor activation, EZN-4176 is unique in its ability to eliminate androgen receptor.
