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

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.

Secondary Endpoints
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

Treatment Arms
ArmTypeDescription
Arm A: AZD4635 + durvalumabEXPERIMENTALAZD4635 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.
Arm B: AZD4635 + durvalumab + cabazitaxelEXPERIMENTALAZD4635 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).
