Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

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
rPFS was defined as the time from first dose to radiographic progression, assessed by the Investigator per RECIST 1.1 (soft tissue) and PCWG3 criteria (bone) or death from any cause, whichever occurred first.
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
OS was defined as the time from first dose until death due to any cause regardless of whether the participant withdrew from study treatment or received another anti-cancer therapy.
Number of Participants With Objective Response in Subjects With MCRPC Who Received AZD4635 Plus Durvalumab Plus Cabazitaxel
Confirmed ORR was defined as the proportion of participants with a confirmed complete response (CR) or partial response (PR) using overall radiographic response assessed by RECIST v1.1 and PCWG-3 criteria (bone), and was based on a subset of all treated participants with measurable disease at baseline per the site Investigator.
Number of Participants With Prostate-specifin Antigen (PSA50) Response in Subjects With MCRPC Who Received AZD4635 Plus Durvalumab Plus Cabazitaxel
Confirmed PSA50 response is defined as the proportion of participants who achieved a ≥50% decrease in PSA from baseline to the lowest post-baseline PSA, confirmed by a consecutive PSA at least 3 weeks later and was based on PSA evaluable participants (dosed participants with an abnormal baseline PSA [≥1 ng/mL]).
Change From Baseline in Worst Pain in the Daily Activities Scales of the Brief Pain Inventory - Short Form (BPI-SF)
"Worst pain" and "Average pain" are 'single question' scores from the BPI short form and may take any value from 0 to 10 (worst outcome). "Interference Pain" is the total score of 7 sub-scores, where each value may take any value from 0 to 10 (worst outcome). The range of the "Interference Score" can be from 0 to 70.
Change From Baseline in Average Pain in the Daily Activities Scales of the Brief Pain Inventory - Short Form (BPI-SF)
"Worst pain" and "Average pain" are 'single question' scores from the BPI short form and may take any value from 0 to 10 (worst outcome). "Interference Pain" is the total score of 7 sub-scores, where each value may take any value from 0 to 10 (worst outcome). The range of the "Interference Score" can be from 0 to 70.
Change From Baseline in Pain Interference in the Daily Activities Scales of the Brief Pain Inventory - Short Form (BPI-SF)
"Worst pain" and "Average pain" are 'single question' scores from the BPI short form and may take any value from 0 to 10 (worst outcome). "Interference Pain" is the total score of 7 sub-scores, where each value may take any value from 0 to 10 (worst outcome). The range of the "Interference Score" can be from 0 to 70.
Number of Participants Who Progressed Based on BPI-SF Item 3
Pain progression was assessed using BPI-SF.
Change From Baseline in the FACT Advanced Prostate Symptom Indext-6 (FAPSI-6), as Derived From 6 Items, the FAPSI-8 From 8 Items Within the FACT-P and the Prostate Cancer Symptoms (PCS), From the 12 Items in the Prostrate-specific Module of the FACT-P
The Functional Assessment of Cancer Therapy-Prostate (FACT-P) will be used to measure health related quality of life (HRQL) in men with prostate cancer. It consists of 4 subscales (physical, emotional, functional and social/family well-being) plus a 12-item prostate-specific module, the PCS subscale, which highlights concerns specific to participants with prostate cancer. FAPSI-6 is defined as a symptom score made up of 6 items from within the FACT-P (pain [n = 3], fatigue [n = 1], weight loss [n = 1], and concerns about the condition getting worse [n = 1]). Each question in the FACT-P questionnaires has a choice of 5 responses, "Not at all", "A little bit", "Somewhat", "Quite a bit" and "Very much". The scores range from 0 ("Not at all") to 4 ("Very much") for positively phrased questions. Negatively phrased questions have a reverse scoring, from 0 ("Very much") to 4 ("Not at all"). This results in a consistent approach, where higher scores indicate a better quality of life.

5. Study Description

Brief Summary
This is a Phase II, international, open-label, two-arm, non-randomised study of AZD4635 in participants with metastatic castration-resistant prostate cancer (mCRPC).
Detailed Description
This is a Phase II, international, open-label, two-arm, non-randomised study of AZD4635 in participants with mCRPC. Participants in each arm will be stratified by the presence of measurable soft tissue metastasis (per Response Evaluation Criteria in Solid Tumours [RECIST v1.1]) or bone-only metastasis (per Prostate Cancer Working Group 3 [PCWG3 criteria]). There will be no formal comparisons between treatment arms. AZD4635 plus durvalumab (Arm A) will consist of 80 participants with mCRPC previously treated with one or more approved new hormonal agent(s) (NHAs) and one or more taxanes or participants who are taxane ineligible. AZD4635 plus durvalumab plus cabazitaxel (Arm B) will consist of 80 participants mCRPC previously treated with docetaxel and one prior NHA. As of November 2020, the Sponsor stopped enrolment in Arm A following decisions at the program level, not related to any safety issues. Ongoing participants in Arm A may continue treatment as planned.
