The U.S. Food and Drug Administration (FDA) has granted Fast Track Designation to HLD-0915, an investigational therapy. This crucial designation is expected to foster more frequent communication between the developing company and the FDA, potentially accelerating the drug’s review and approval process.

HLD-0915 is an orally administered, bifunctional small molecule therapy that operates as a RIPTAC, a novel class of molecules designed to selectively target cancer cells. Its unique mechanism involves inducing proximity between a tumor-specific protein (TP) and an essential effector protein (EP).Specifically, HLD-0915 is engineered to bind to the androgen receptor (AR) and effector proteins, forming a stable trimeric complex. This complex then disrupts an essential function within the cancer cells, leading to their selective death and demonstrating antitumor activity. This innovative approach offers a new, oral, and selective cancer cell-killing mechanism with the potential to overcome drug resistance, making it applicable for both advanced cases where resistance has emerged and in early-stage disease where the tumor-specific protein is expressed.

Additionally, patients who have received systemic anticancer therapy or other investigational drugs within two weeks before the first dose of HLD-0915 are not eligible.
