A Study of Metastases Free Survival With Saruparib vs Placebo Added to a Standard RT/ADT in Men With High-risk Prostate Cancer With a BRCA Mutation
(EvoPAR-PR02)
What this study is about
The purpose of the study is to demonstrate superiority of Saruparib (AZD5305) relative to placebo added to a standard radiation therapy (RT) + androgen deprivation therapy (ADT) regimen by assessment of metastases-free survival in participants with high-risk and very high-risk localised/locally advanced prostate cancer with a breast cancer gene mutation (BRCAm).
View original scientific description
The purpose of the study is to demonstrate superiority of Saruparib (AZD5305) relative to placebo added to a standard radiation therapy (RT) + androgen deprivation therapy (ADT) regimen by assessment of metastases-free survival in participants with high-risk and very high-risk localised/locally advanced prostate cancer with a breast cancer gene mutation (BRCAm).
Interventions
DRUG
Saruparib
Saruparib will be administered orally.
DRUG
Placebo
Matching placebo to saruparib will be administered orally.
DRUG
Abiraterone + Prednisolone/Prednisone
Abiraterone will be administered orally in combination with prednisone/prednisolone.
DRUG
Androgen Deprivation Therapy (ADT)
Standard of care ADT will be administered.
Primary outcome measures
Metastasis-free survival (MFS)
Time frame: Up to approximately 93 months
MFS is defined as the time from randomisation until the date of first appearance of distant metastases, confirmed by standard clinical imaging \[computed tomography (CT)/ magnetic resonance imaging (MRI) and bone scan, or prostate-specific membrane antigen-positron emission tomography (PSMA-PET)\], as assessed by blinded independent central review (BICR) or death due to any cause.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male participants with a histologically documented diagnosis of prostate adenocarcinoma.
- Newly diagnosed high-risk and very high-risk (localised/locally advanced) prostate cancer or a high-risk biochemical recurrence (BCR) following radical prostatectomy.
- Provision of a formalin fixed and paraffin embedded (FFPE) tumour tissue sample.
- Confirmed BRCA1 or BRCA2 mutation status by central tumour tissue is required for enrolment.
- Participants required to have a computed tomography (CT) or magnetic resonance imaging (MRI) and a bone scan following the completion of their planned RT. This screening scan must confirm no evidence of disease or evidence of disease confined to the pelvis (M0).
- Participants required to have a prostate-specific membrane antigen-positron emission tomography (PSMA-PET) following the completion of their planned RT. This screening scan must confirm no evidence of disease or evidence of disease confined to the pelvis (M0).

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
