Ovarian Cancer Clinical Trial
Adavosertib With or Without Olaparib in Treating Patients With Recurrent Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
This phase II trial studies how well adavosertib with or without olaparib work in treating patients with ovarian, primary peritoneal, or fallopian tube cancer that has come back (recurrent). Adavosertib and olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
I. To determine the objective response rate (ORR) as determined by Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST 1.1) of adavosertib (AZD1775) alone or in combination with olaparib in women with recurrent ovarian cancer in whom progression has been documented following poly ADP-ribose polymerase (PARP) inhibitor therapy.
I. To evaluate the overall safety and tolerability of AZD1775 alone or in combination with olaparib in this population.
II. To evaluate the disease control rate (DCR) = overall response rate (ORR) plus stable disease rate for 16 weeks.
III. To evaluate the progression free survival (PFS) and overall survival (OS) of this population following AZD1775 alone or in combination with olaparib.
IV. To evaluate the duration of response by RECIST version (v)1.1.
I. To evaluate the efficacy of each arm by BRCA-mutation status (BRCA-mt) and homologous recombination deoxyribonucleic acid (DNA) repair deficiencies (HRD).
II. To describe endogenous and dynamic markers of DNA damage response in tumor tissue and circulating surrogates, such as circulating tumor cells (CTC), circulating tumor DNA (ctDNA), exosomes (cellular/nuclear), cell cycle kinetics (CDKs), and immunophenotype.
III. To examine genomic alterations associated with response and mechanisms of resistance to olaparib and/or AZD1775.
OUTLINE: Patients are randomized to 1 of 2 arms. If enrollment pauses for 1 arm, patients will be assigned to the enrolling arm. Study has a new arm 3 and enrolling patients.
ARM I: Patients receive adavosertib orally (PO) once daily (QD) on days 1-5 and 8-12. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive olaparib PO twice daily (BID) on days 1-21 and adavosertib PO QD on days 1-3 and 8-10. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Arm III: Patient receive ceralasertib tablets by PO BID each day on Days 1-14. You will also take olaparib tablets by PO BID each day on Days 1-28.
After completion of study treatment, patients are followed up for 30 days and periodically afterwards.

Inclusion criteria for ceralasertib arm only:
Must have platinum-sensitive disease, defined as no clinical or radiographic evidence of disease recurrence for > 6 months (or 180 days) after last receipt of platinum- based therapy. Patients must have had response (complete or partial) to their prior line of platinum therapy and cannot have had progression through prior platinum-based therapy.
Have demonstrated progressive disease while taking a licensed PARP inhibitor as a previous therapy, used in the maintenance or treatment setting.
Are germline or somatic BRCA mutant or HRD positive by a licensed test prior to enrollment.
Patient must have demonstrated clinical benefit from prior PARPi treatment. Clinical benefit after >1 line of chemotherapy is defined as a minimum duration of continuous treatment with the PARP inhibitor of 6 months in the treatment or maintenance setting (which may or may not be associated with response by CA-125 or imaging). If the PARP inhibitor is received as maintenance following first-line chemotherapy, the minimum duration of continuous treatment with the PARP inhibitor is 12 months
Patients who discontinue the PARP inhibitor for any reasons other than progression are ineligible
If the prior PARP inhibitor used was olaparib, then patients must have received treatment without significant toxicity or the need for a permanent dose reduction.
Documented evidence of progression prior to study entry.
PARP inhibitor: Most oral PARP inhibitors (the immediate prior therapy) have a half- life for which 5 half-lives is ≤21 days. Thus, a minimum of 10 days between termination of the prior treatment and administration of olaparib and/or AZD1775 treatment is required. In the event a PARP inhibitor has a longer half-life where 5 half-lives are ≥ 21 days, treatment of olaparib and/or AZD1775 should not begin for 5 half-lives or at least 21 days, whichever is shorter.
Any hormonal therapy directed at the malignant tumor must be discontinued at least one week prior to registration (study enrollment). Continuation of hormone replacement therapy is permitted.
Any other prior therapy directed at the malignant tumor, including any systemic immunologic agents, must be discontinued at least three weeks prior to first dose of study drug (6 weeks for nitrosoureas or mitomycin C).
Cytotoxic chemotherapy, hormonal or non-hormonal targeted therapy within 21 days of Cycle 1 Day 1 is not permitted (a duration of 30 days or 5 half-lives (whichever is shorter) is required for patients treated with non-cytotoxic drugs). The minimum washout period for immunotherapy is 42 days. Palliative radiotherapy must have been completed 21or more days before Cycle 1 Day 1 (with the exception of patients receiving radiation to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of study treatment).

Receiving, or having received during the 14 days prior to first dose, corticosteroids (at a dose > 10 mg prednisone/day or equivalent) for any reason.
Major surgical procedures ≤28 days of beginning study treatment, or minor surgical procedures ≤7 days. No waiting period required following port-a-cath placement.
Grade >1 toxicity from prior therapy (except alopecia or anorexia).
Patient has an inability to swallow oral medications and patients with gastrointestinal disorders likely to interfere with absorption of the study medication. Note: Patient may not have a percutaneous endoscopic gastrostomy (PEG) tube or be receiving total parenteral nutrition (TPN). Patient has refractory nausea and vomiting, chronic gastrointestinal diseases or previous significant bowel resection, with clinically significant sequelae that would preclude adequate absorption of the study medication.
Patients with symptomatic uncontrolled brain metastases. Patients with a history of treated central nervous system (CNS) metastases are eligible provided they meet all of the following criteria: disease outside the CNS is present, no clinical evidence of progression since completion of CNS-directed therapy, minimum 3 weeks between completion of radiotherapy and Cycle 1 Day 1 and recovery from significant (Grade ≥ 3) acute toxicity with no ongoing requirement for >10 mg of prednisolone per day or an equivalent dose of other corticosteroid. If on corticosteroids, the patient should be receiving a stable dose of corticosteroids, started at least 4 weeks prior to treatment.
Patient has had a prescription or non-prescription drugs or other products known to be sensitive to CYP3A4 substrates or CYP3A4 substrates with a narrow therapeutic index, or to be moderate to strong inhibitors/inducers of CYP3A4 which cannot be discontinued 2 weeks prior to Day -3 of dosing and withheld throughout the study until 2 weeks after the last dose of study drug. Co- administration of aprepitant or fosaprepitant during this study is prohibited (see Appendix G).
The use of herbal supplements or 'folk remedies' (and medications and foods that significantly modulate CYP3A activity) should be discouraged. These herbal medications include but are not limited to: St. John's wort, kava, ephedra (mahung), gingko biloba, dehydroepiandrosterone (DHEA), yohimbe, saw palmetto and ginseng. Patients should stop using herbal medications 7 days prior to first dose of study treatment.
