Radiographic PFS (rPFS) is the primary endpoint of this study, defined as the time from randomization to radiographic progression, as assessed by the investigator per RECIST 1.1 (soft tissue) and/or PCWG3 criteria (bone), or death due to any cause.
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.
PFS is defined as time from randomisation until progression per RECIST v1.1 as assessed by BICR, or death due to any cause.

A DLT is defined as any toxicity that occurs from the first dose of study treatment (either AZD5305 or combination anti-cancer agent) up to and including the planned end of Cycle 1 (the DLT assessment period) that is assessed as unrelated to the disease or disease-related processes under investigation. DLTs occurring outside the DLT window (ie, late onset toxicities) may be defined as a DLT after consultation with the sponsor and investigators, based on the emerging safety profile.

Saruparib is an investigational oral medicine being studied in oncology for advanced breast cancer, advanced solid malignancies, locally advanced or metastatic solid tumors, and prostate cancer, including metastatic hormone-sensitive prostate cancer and metastatic castration-sensitive prostate cancer. It is not yet approved and remains in clinical development.
Saruparib targets PARP1, a poly (ADP-ribose) polymerase enzyme involved in DNA repair. It belongs to the -parib class of PARP inhibitors. By binding PARP1, saruparib is designed to interfere with DNA damage repair in tumor cells, and it is being evaluated in biomarker-selected patient populations.
Saruparib is being developed by AstraZeneca PLC, which trades on the Nasdaq under the ticker AZN. AstraZeneca sponsors the clinical program, including the Phase 3 EvoPAR-PR05 study in metastatic hormone-sensitive prostate cancer and other trials in solid tumors.
Saruparib is in Phase 3 clinical development. The program includes Phase 3 trials in metastatic hormone-sensitive prostate cancer and in high-risk prostate cancer with a BRCA mutation, along with earlier-phase studies. Saruparib is investigational and has not been approved by the FDA.
Saruparib trials include NCT07711002, a recruiting Phase 3 study of saruparib plus physician's choice of ARPI in metastatic hormone-sensitive prostate cancer, and NCT06952803, a recruiting Phase 3 study of saruparib versus placebo added to standard radiotherapy and androgen deprivation therapy in high-risk prostate cancer with a BRCA mutation. NCT07832630 and NCT06899061 are also listed.
Yes. Saruparib is also known as AZD5305. The names saruparib (AZD5305) and AZD5305 microtracer, including [14C]-AZD5305 microtracer, refer to the same AstraZeneca PARP1-targeting compound studied across the saruparib clinical program.
