Study Summary

CCW702 is an investigational immunotherapy for prostate cancer. This is a two-part, first-in-human study to assess the safety and tolerability of CCW702 administered subcutaneously to patients with metastatic, castration resistant prostate cancer. Part I is divided in to two subparts, in both subparts patients will receive ascending dosages of CCW702 with the goal to determine the maximum tolerated dose (MTD) of CCW702 and efficacious regimen. Part Ia will explore every other other day dosing (QOD); Part Ib will explore weekly dosing (Q7D). In part II of the study, patients will be given the recommended part/phase 2 dose (RP2D) Q7D. The study will also assess the pharmacokinetics and pharmacodynamics of CCW702.
