• +Histologically or cytologically confirmed malignancy of the pancreas, prostate, breast, or ovary.
• +Documented evidence of pathogenic or likely pathogenic somatic or germline mutation in BRCA1/2 and/or PALB2, and/or any genetic alterations listed below as indicated in a Clinical Laboratory Improvement Amendments (CLIA)-certified laboratory report. The report must be submitted to and approved by study sponsorSponsorThe organisation responsible for the study overall.Read more → prior to registration.

• +\* In addition to the genes already specified, the "FANC family" genes may also include the following: FANCE, FANCF, FANCG, FANCM, FANCP, FANCQ/ERCC4/XPF, FANCR/RAD51, FANCT/UBE2T, FANCU/XRCC2, FANCV/REV7/MAD2L2, and FANCW/RFWD3.
• +Exploratory cohort:
• +Histologically confirmed ovarian, fallopian tube or primary peritoneal cancer, with a high grade serous or high grade endometrioid histology subtype.
• +Documented evidence of pathogenic or likely pathogenic germline mutation or a clinically actionable somatic mutation in BRCA1 and/or other HRD-associated mutation, as indicated in a CLIA-certified laboratory report. The report must be submitted to and approved by study sponsor prior to registration.
• +Meet one of the following criteria:
• +All participants:
• +Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 within 14 days of registration.
• +Radiographically documented disease progression within 28 days of registration and evaluable as per RECIST v1.1.
• +Patient must have measurable disease as per RECIST v1.1.
• +Patients must have adequate bone marrow, renal and hepatic function per local laboratory reference ranges as follows within 14 days of registration:
• +Absolute Neutrophil Count ≥ 1.5 x 10\^9/L
• +Platelets ≥ 100 x 10\^9/L
• +Hemoglobin ≥ 9 g/dL (blood transfusion ≤ 7 days of screeningScreeningThe checks done before joining, to see whether a study fits.Read more → not permitted).
• +Calculated creatinine clearance \> 51mL/min (Cockcroft-Gault formula)
• +AST/ALT ≤ 2.5× the upper limit of normal (ULN). Subjects with liver metastasis may have AST, ALP, and ALT ≤ 5.0 X ULN.
• +Bilirubin ≤ 1.5×ULN. This will not apply to patients with confirmed Gilbert's syndrome (persistent or recurrent hyperbilirubinemia that is predominantly unconjugated in the absence of haemolysis or hepatic pathology), who will be allowed only at the discretion of the Study InvestigatorPrincipal investigatorThe doctor or researcher responsible for running the study at a site.Read more →.
• +INR/PT and aPTT ≤1.5 X ULN unless patient is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants.
• +Albumin ≥3.0 g/dL
• +Patients are willing to undergo tumour biopsy pre-treatment and at time of progression on treatment. If a biopsy at the time of progression on prior therapy is available and can be submitted to the Central Lab for this study, this procedure does not need to be repeated. Patients who consentInformed consentThe process of being told what taking part involves, then choosing freely.Read more → but have tumour that is not amenable to safe biopsy will be allowed to enter the trial and continue therapy as per protocolProtocolThe detailed plan a study must follow.Read more → if this has been addressed and permission is granted from the sponsor prior to registration.
• +Life expectancy of greater than 3 months from the date of registration.
• +Able to provide written informed consent.
• +Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow upFollow-upContinued check-ins after the treatment part is finished.Read more →.
• +There is no minimum or maximum number of lines of prior therapy and prior PARP inhibitor therapy is allowed.
• +Patient is clinically stable at the time of entering the study.
• +Female patients of childbearing potential must have a negative serum pregnancy test within 14 days prior to registration. (Note: a negative urine/serum pregnancy test is required on Cycle 1, Day 1 prior to treatment unless the screening pregnancy test was done within 48hrs of registration).
• +Female patients of childbearing potential and male patients who are sexually active must agree to practice true abstinence or at least two effective methods of contraception (ie: condoms with spermicide, hormonal methods such as oral contraceptive pills, vaginal ring, injectables, implants and intrauterine devices (IUDs), non-hormonal IUDs, such as ParaGard, bilateral tubal ligation, vasectomy, complete abstinence) within 14 days prior to registration, and agree to continue using such precautions while on treatment with CX-5461 (including dose interruptions) and for 6 months following the last dose of CX-5461.
• +Platinum Sensitive with no evidence of disease progression within 6 months of the last dose of platinum-based chemotherapy (n=10 patients); OR
• +Platinum Resistant with disease progression within 6 months of the last dose of a platinum-based chemotherapy.
