ORIC-533 is a selective, orally bioavailable, small molecule inhibitor of CD73.This is an open-label, uncontrolled, multicenter, dose-finding study to assess the safety and preliminary antimyeloma activity of ORIC-533 in patients with relapsed or refractory multiple myeloma.~After the RP2D has been determined, dose expansion will further evaluate safety and preliminary antimyeloma activity of ORIC-533 in patients with relapsed or refractory multiple myeloma.
The purpose of this study is to establish the Recommended Phase 2 Dose (RP2D), safety, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary antimyeloma activity of ORIC-533 in patients with multiple myeloma who have exhausted available treatment options
