RLY-4008 (REFOCUS)

A First-in-Human Study of Highly Selective FGFR2 Inhibitor, RLY-4008, in Patients with intrahepatic Cholangiocarcinoma and Other Advanced Solid Tumors

This is a Phase 1/2, open-label, first-in-human study designed to evaluate the safety, tolerability, PK, PDy*, and antineoplastic activity** of RLY-4008, a potent and highly selective FGFR2 inhibitor, in patients with unresectable or metastatic CCA and other solid tumors. The study consists of 3 parts: a dose escalation (Part 1), a dose expansion (Part 2), and an extension (Part 3).

*PK and PDY = Pharmacokinetics (PK) represents “what the body does to the drug,” whereas pharmacodynamics (PD) can be defined as “what the drug does to the body,” or, more specifically, to target cell-types, tissues, or organs.

** antineoplastic activity = Blocking the formation of neoplasms (growths that may become cancer).
