Cirtuvivint/Olaparib in Breast Cancer Susceptibility Gene/Homologous Recombination Deficiency Platinum Resistant Ovarian Cancer

Summary

The purpose of this study is to learn about the safety and tolerability of Cirtuvivint in combination with Olaparib in platinum resistant ovarian cancer. The study also aims to determine the recommended dose of the combination therapy. If a participant is a good fit for the study, and they enroll in the study, they will: * Visit the clinic often at the beginning of the study for physical exams, blood draws, vital signs, and other study and routine care procedures. After the first two months participants will visit the clinic every 28 days. * Take the study medications, Cirtuvivint and Olaparib. Participants will take Olaparib every day. Participants will either take Cirtuvivint 5 days per week or 2 days per week.

   * Hormonal therapy will be counted as a separate line of therapy unless it was given as maintenance
   * Prior radiation is allowed and is not considered a line of treatment
9. Patients must have had testing for BRCA mutation (tumor or germline) and tumor HRD testing, and have been positive for one and/or the other.
10. Patients must have received a prior PARP inhibitor as either treatment or maintenance therapy
11. Patients must have adequate hematologic, liver, and kidney function as defined as:

    * Hemoglobin ≥ 10.0 g/dL with no blood transfusion in the past 28 days
    * Serum creatinine ≤ 1.5 x upper limit of normal (ULN)
    * Patients must have creatinine clearance estimated of ≥51 mL/min using the Cockcroft-Gault equation or based on a 24 hour urine test
    * Aspartate aminotransferase (AST)(Serum Glutamic Oxaloacetic Transaminase (SGOT)) and alanine aminotransferase (ALT) (Serum Glutamic Pyruvate Transaminase (SGPT)) ≤ 2.5 x ULN unless liver metastases are present in which case they must be ≤ 5x ULN
    * Serum bilirubin ≤ 1.5 x ULN (patients with documented diagnosis of Gilbert syndrome are eligible if total bilirubin \< 3.0 x ULN)
    * Serum albumin ≥ 2 g/dL
12. Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial.
13. Ability to understand and the willingness to sign a written informed consent document. Participants with impaired decision-making capacity (IDMC) who have a legally-authorized representative (LAR) and/or family member available will also be eligible.

Exclusion Criteria:

1. Patients with clear cell, mucinous, sarcomatous, low grade/borderline, germ cell, or sex-cord stromal type ovarian tumor
2. Patients with platinum refractory disease as defined by those who have progressed during or within 4 weeks of receiving platinum-based therapy
3. Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within 3 weeks prior to study treatment
4. Patients with myelodysplastic syndrome/acute myeloid leukemia or with features suggestive of myelodysplastic syndrome/acute myeloid leukemia.
5. Patients considered a poor medical risk due to a serious, uncontrolled medical disorder, non-malignant systemic disease or active, uncontrolled infection. Examples include, but are not limited to:

   * Uncontrolled major seizure disorder
   * Unstable spinal cord compression
   * Any psychiatric disorder that prohibits obtaining informed consent.

   * Unstable angina pectoris
   * Uncontrolled congestive heart failure (New York Heart Association \> class II)
   * Uncontrolled ≥ Grade 3 hypertension (per CTCAE)
   * Uncontrolled cardiac arrhythmias
7. Patients with a history of hemorrhagic or ischemic stroke within 6 months prior to enrollment
8. Patients with a history of cirrhotic liver disease (Child-Pugh Class B or C)
9. Persistent toxicities (\>/= Common Terminology Criteria for Adverse Event (CTCAE) grade 2) caused by previous cancer therapy, excluding alopecia or peripheral sensory neuropathy
10. Patients with duodenal stent or other GI disorder/defect that would interfere with absorption of oral medication

    o Includes patients unable to swallow orally administered medication and patients with gastrointestinal disorders likely to interfere with absorption of the study medication
11. Patients with known untreated or symptomatic central nervous system (CNS) metastases
12. Prior known hypersensitivity reaction to study drugs and/or any of their excipients
13. Minor or major surgical procedure within 2 weeks of starting study treatment and patients must have recovered from any effects of any major surgery.
