Brief 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. In part I, patients will receive ascending dosages of CCW702 with the goal to determine the maximum tolerated dose (MTD) of CCW702. In part II of the study, patients will be given the recommended phase 2 dose (RP2D) evaluating two regimens of CCW702 to determine which regimen is most efficacious. The study will also assess the pharmacokinetics and pharmacodynamics of CCW702.

Arm Intervention/treatment
Experimental: Part 1: Dose Escalation
CCW702 is administered subcutaneously with ascending dose levels to determine maximal tolerated dose (MTD).
 Drug: CCW702
Investigational immunotherapy for prostate cancer
Experimental: Part 2: Dose Expansion
CCW702 is administered subcutaneously at the recommended phase 2 dose (RP2D). Different dosing regimens will be compared.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Part 1, Dose escalation: to assess the safety and tolerability of increasing doses of CCW702: number of first cycle dose limiting toxicities [ Time Frame: up to 4 weeks ]
    Measure the number of first cycle dose limiting toxicities

  2. Part 2, Dose expansion: to assess clinical efficacy at the recommended phase 2 dose. [ Time Frame: up to 2 years ]
    Responses will be measured using prostate cancer working group 3 (PCWG3) criteria
