简要总结

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).

入选标准

  • Male participants with a histologically documented diagnosis of prostate adenocarcinoma
  • Newly diagnosed high risk and very high risk (localised or 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)
  • Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 with no deterioration over the 2 weeks prior to randomization.
  • Minimum life expectancy of 12 months.
  • Adequate organ and bone marrow function as described in study protocol.
  • All participants will have received either primary or salvage RT.
  • Radiotherapy administered to the prostate (pelvis) either in the primary or salvage setting must be delivered with curative intent.
  • All participants will have received a planned regimen of ADT with a gonadotropin releasing hormone (GnRH) analogue.
  • Participants must not father children or donate sperm from signing informed consent form (ICF), during the study intervention and for 6 months after the last dose of study intervention.

排除标准

  • Participants with a history of myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) or with features suggestive of MDS or AML.
  • Participants with any known predisposition to bleeding [example active peptic ulceration, recent (within 6 months) hemorrhagic stroke, proliferative diabetic retinopathy].
  • Any history of persisting (greater than 2 weeks) severe cytopenia due to any cause.
  • Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product or previous significant bowel resection that would preclude adequate absorption of saruparib and or abiraterone.
  • History of another primary malignancy, with exceptions.
  • Persistent toxicities [Common Terminology Criteria for Adverse Events (CTCAE) Grade greater than or equal to 2] caused by previous anticancer therapy.
  • Cardiac criteria, including history of arrhythmia and cardiovascular disease.
  • Evidence of active and uncontrolled hepatitis B and or hepatitis C.
  • Evidence of active and uncontrolled human immunodeficiency virus (HIV) infection.
  • Active tuberculosis infection.
  • Any prior chemotherapy (i.e., docetaxel) or immunotherapy, any prior treatment with a poly (ADP ribose) polymerase (PARP) inhibitor.
  • Prior treatment within 14 days with blood product support or growth factor support.
  • Concomitant use of strong inducers and inhibitors of CYP3A4 (applies to saruparib and abiraterone) or herbal supplements within 21 days or at least 5 half lives (whichever is longer), of randomization.
  • Concomitant use of drugs that are known to prolong QT and have a known risk of Torsades de Pointes (TdP).
  • Participants with a known hypersensitivity to saruparib or any excipients of these products.

结局指标

主要结局

Metastasis-free survival (MFS)

时间窗: 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.

时间窗: Up to approximately 93 months

次要结局

  • Overall Survival (OS)(OS is defined as the time from randomisation until the date of death due to any cause.)
  • MFS (CT/MRI and bone scan)(MFS is defined as the time from randomisation until the date of distant metastases, confirmed by conventional imaging (CT/MRI and bone scan), or death due to any cause.)
  • MFS (PSMA-PET)(MFS is defined as the time from randomisation until the date of distant metastases, confirmed by PSMA-PET imaging or death due to any cause.)
  • MFS (standard clinical imaging)(MFS is defined as the time from randomisation until the date of distant metastases, confirmed by standard clinical imaging (CT/MRI and bone scan or PSMA-PET), histology, or death due to any cause.)
  • Time from randomisation to Progression Free Survival 2 (PFS2)(Time from randomisation to PFS2 is defined as the time from randomisation to the earliest of progression [defined as radiographic progression, clinical progression, or prostate-specific antigen (PSA) progression] after initiation of first subsequent systemic treatment following the initial investigator-assessed progression or death. The date of second progression will be investigator assessed according to local standard clinical practice.)
  • Time to biochemical recurrence(Time to biochemical recurrence is defined as the time from randomisation to biochemical recurrence per Phoenix criteria.)
  • Prostate cancer-specific survival (PCSS)(PCSS is defined as the time from randomisation until the date of death due to the underlying prostate cancer.)
  • Time to deterioration in urinary symptoms (TTDUS)(TTDUS is defined as the time from randomisation to deterioration in EORTC-QLQ-PR25 (US) subscale scores.)
  • Time to deterioration in physical function (TTDPF)(TTDPF is defined as the time from randomisation to deterioration in EORTC-QLQ-C30 Physical Function subscale scores.)
  • Plasma concentrations of saruparib(To assess the PK of saruparib in plasma either with or without abiraterone and explore the relationship between the PK concentration/parameters and selected endpoints (which may include pharmacodynamic parameters, efficacy, and/or safety).)
  • Area under the curve (AUC)(To assess the PK of saruparib in plasma either with or without abiraterone and explore the relationship between the PK concentration/parameters and selected endpoints (which may include pharmacodynamic parameters, efficacy, and/or safety).)
  • Maximum observed concentration (Cmax)(To assess the PK of saruparib in plasma either with or without abiraterone and explore the relationship between the PK concentration/parameters and selected endpoints (which may include pharmacodynamic parameters, efficacy, and/or safety).)
  • Time to Cmax (Tmax)(To assess the PK of saruparib in plasma either with or without abiraterone and explore the relationship between the PK concentration/parameters and selected endpoints (which may include pharmacodynamic parameters, efficacy, and/or safety).)
  • Number of participants with adverse events (AEs)(To assess the safety and tolerability of saruparib administered in combination with ADT alone (Cohort A) and in combination with ADT + abiraterone (Cohort B).)
