Outcome Measures

Primary Outcomes (1)

  • Radiographic Progression Free Survival (rPFS) in Each Arm Separately to Determine the Efficacy of AZD4635 Plus Durvalumab and of AZD4635 Plus Durvalumab Plus Cabazitaxel in Patients With Metastatic Castrate-resistant Prostate Cancer (mCRPC)

    rPFS was defined as the time from first dose to radiographic progression, assessed by the Investigator per RECIST 1.1 (soft tissue) and PCWG3 (Prostate Cancer Working Group 3) criteria \[bone\] or death from any cause, whichever occurred first.

    From first dose to first documented progression or death from any cause (whichever comes first) (approximately 1 year)

Secondary Outcomes (16)

  • rPFS by Adenosine (ADO) Signalling Gene Expression in High and Low Subgroups to Determine the Efficacy of AZD4635 Plus Durvalumab Plus Cabazitaxel in Participants With mCRPC

    From first dose to first documented progression or death from any cause (whichever comes first), up to two years

  • Overall Survival (OS) in Each Arm Separately to Determine the Efficacy of AZD4635 Plus Durvalumab and of AZD4635 Plus Durvalumab Plus Cabazitaxel in Participants With mCRPC

    Arm A and B: Every 90 days from the last dose of study drug up to 2 years

  • Number of Participants With Objective Response in Subjects With MCRPC Who Received AZD4635 Plus Durvalumab Plus Cabazitaxel

    From first dose to first documented progression or death from any cause (whichever comes first), up to two years

  • Number of Participants With Prostate-specifin Antigen (PSA50) Response in Subjects With MCRPC Who Received AZD4635 Plus Durvalumab Plus Cabazitaxel

    Arm A: Screening, Day 1 of each cycle up to 11 months (Each cycle was 28 days in length); Arm B: Screening, Day 1 of each cycle up to 11 months (Cycle 1 to Cycle 10 = 21 days, Cycle 11 onwards = 28 days)

  • Change From Baseline in Worst Pain in the Daily Activities Scales of the Brief Pain Inventory - Short Form (BPI-SF)

    Arm A: Screening, Day 1 of each cycle up to 9 months (Each cycle was 28 days in length); Arm B: Screening, Day 1 of each cycle up to 9 months (Each cycle was 21 days in length)

  • +11 more secondary outcomes

Study Arms (2)

Arm A: AZD4635 + durvalumab

EXPERIMENTAL

AZD4635 plus durvalumab (Arm A) will consist of participants with mCRPC previously treated with one or more approved NHAs (eg, abiraterone acetate, enzalutamide, apalutamide and/or darolutamide), and one or more taxanes, or participants who are taxane ineligible.

Drug: AZD4635Drug: Durvalumab

Arm B: AZD4635 + durvalumab + cabazitaxel

EXPERIMENTAL

AZD4635 plus durvalumab plus cabazitaxel (Arm B) will consist of participants with mCRPC previously treated with docetaxel and one prior NHA (either abiraterone acetate or enzalutamide but not both (prior apalutamide is not allowed in Arm B).

Drug: AZD4635Drug: DurvalumabDrug: Cabazitaxel

Interventions

Subjects will receive AZD4635 orally daily

Arm A: AZD4635 + durvalumabArm B: AZD4635 + durvalumab + cabazitaxel

Subjects will receive intravenous durvalumab every 4 weeks for Arm A and every 3 weeks for Arm B.

Arm A: AZD4635 + durvalumabArm B: AZD4635 + durvalumab + cabazitaxel

Subjects will receive intravenous cabazitaxel every 3 weeks

Arm B: AZD4635 + durvalumab + cabazitaxel

Eligibility Criteria

  • Adequate bone marrow reserve and organ function.
  • Adequate organ function for Arm A as demonstrated by all of the following laboratory values:
  • Alanine aminotransferase (ALT) ≤2.5 × upper limit of normal (ULN) if no demonstrable liver metastases or ≤5 × ULN in the presence of liver metastases.
  • Aspartate aminotransferase (AST) ≤2.5 × ULN if no demonstrable liver metastases or ≤5 × ULN in the presence of liver metastases

  • +11 more criteria

You may not qualify if:

  • Active brain metastases or leptomeningeal metastases.
  • There must be no requirement for immunosuppressive doses of systemic corticosteroids for at least 2 weeks prior to study enrollment.
  • History of pneumonitis requiring corticosteroids, second malignancy that is progressing and/or received active treatment ≤3 years before the first dose of study intervention, and hypersensitivity to polysorbate-80 if allocated to cabazitaxel.
  • As judged by the Investigator, any evidence of severe or uncontrolled systemic diseases.
  • Creatinine clearance \<40 mL/min (calculated by Cockcroft-Gault equation).
  • Prior exposure to immune-mediated therapy including.
  • Ongoing treatment with warfarin (Coumadin).
  • Major surgery (excluding placement of vascular access) within 4 weeks of the first dose of study intervention.
