Brief Summary:

Investigational agent, AZD6738 will be given in combination with Olaparib to women with recurrent ovarian cancer (platinum-sensitive or platinum-resistant).

This study will determine if using Olaparib in combination with AZD6738 is safe and tolerable and also determine the objective response rate and progression free survival of combination of AZD 6738 and Olaparib in women with recurrent ovarian cancer in distinct Pt-sensitive and Pt-resistant cohorts.

Condition or disease Intervention/treatment Phase
High Grade Serous Carcinoma Drug: Olaparib Pill Phase 2

Detailed Description:

Women 18 years or older, who have recurrent ovarian cancer will be enrolled in this study. After consenting to participate in this trial, they will undergo screening process which will involve medical exam and blood work. If found eligible to participate in the trial, they will be given olaparib to be taken on all 28 days of the cycle and investigational AZD 6738 from days 1-7. For the first cycle, the subject will need to come in every week for lab tests and physical exam - this will help the treating physician determine an adverse event as soon as it happens. After that, patients are expected to come in every month at the end of each cycle (each cycle is 28 days).

Patients will undergo scans for tumor assessments every 2 cycles and if stable disease or response to therapy is documented after cycle 4, imaging will continue every 3 cycles thereafter.

Arm Intervention/treatment
Experimental: 1- Olaparib Pill + AZD6738.

All patients will receive the combination of AZD6738 and olaparib. Patients will be administered olaparib orally twice daily at 300 mg BD. Patients will be administered AZD6738 orally once daily at 160 mg on days 1 to 7.

For ease of administration, the AZD6738 should be administered at the same time as one of the olaparib doses and thus with one glass of water.

Drug: Olaparib Pill

For Cohorts A, B, and C:

Olaparib is prescribed at 300 mg twice daily by mouth (taken as two 150 mg tablets 12 hours apart) which is taken continuously for 28 days, which is one cycle. The tablets should be taken at the same time each day, approximately 12 hours apart with one glass of water.

AZD6738 is prescribed at 160 mg orally once daily for first 7 days of every cycle (Days 1-7 of each 28-day cycle). You will take one 100 mg tablet and three 20mg tablets (for a total of 160mg) once daily after taking your olaparib tablets in the morning.

Cohort D: a lower dose of olaparib (100-200mg daily for a 28-day cycle) and a higher dose of AZD6738 (160-320 mg daily for about 14 days). Three to five dosing schedules will be evaluated.

Other Name: investigational AZD6738

  3. For Cohorts A-C, and Cohort D, Part II, patients must have high grade serous ovarian, primary peritoneal, and/or fallopian tube cancer histologically or cytologically confirmed that is recurrent and for which standard curative measures do not exist or are no longer effective. For Cohort D, Part I, patients may have any non-mucinous epithelial ovarian cancer (including histology's such as clear cell, or endometrioid). Pathology must be reviewed internally at the University of Pennsylvania, Johns Hopkins University, or Harvard University prior to initiation of treatment.
  4. All patients under consideration for Cohorts A, B, C, and D Part II, must be willing to undergo mandatory tumor biopsies (non-target lesion). Patients should have at least one lesion (non-target) for biopsy. However, for 50% of patients in Cohorts A, B, C, and D Part II, if patients are found to not have a safe lesion to biopsy by the radiology team, they may still be enrolled in the study and forego the biopsy. Patients for consideration for Cohort D Part I (dose escalation) are not required to undergo a biopsy for enrollment. Patients who undergo attempted biopsies that are unsuccessful may still enroll and receive study drug.
  5. All patients must have a measurable disease by RECIST v1.1.
  6. Germline BRCA mutation status:

    • Cohorts A and B: Patients with unknown BRCA status or negative BRCA germline mutation status will be permitted to enroll in the study. Patients with known BRCA germline mutations will be permitted to enroll up to a maximum of 10 subjects per cohort.
    • Cohort C and Cohort D Part II: All subjects must have either a germline or somatic BRCA mutation, or other HRD mutation, or tumor is HRD positive. Other HRD mutations will be reviewed for consideration for enrollment by SRC or University of Pennsylvania PI.
    • Cohort D Part I: Patients will be enrolled irrespective of BRCA status.
  7. Adequate renal function, defined as measured creatinine clearance ≥ 51 ml/min.
  8. Adequate hepatic function, defined as AST and ALT levels ≤ 2.5 X ULN (for subjects with liver metastases, AST or ALT ≤ 5 × ULN) and total bilirubin < 1.5 X ULN, absent Gilbert's disease.

  10. Patients must be at least 2 weeks from previous therapy (chemotherapy, hormonal therapy, and radiation therapy, or investigational agents; 6 weeks for mitomycin C) to initiate screening and 3 weeks from previous therapy to initiate treatment.
  11. Platinum-sensitive is defined as recurrence >6 months by RECIST 1.1 imaging from last platinum. Platinum-resistant is defined as recurrence < 6 months by RECIST 1.1 imaging from last platinum regimen).

    • For Cohort A, there is no limit to number of prior regimens.
    • For Cohort B, patients may not have had more than 3 prior cytotoxic therapies since the development of platinum-resistance.
    • Patients for Cohort D, Part I (dose escalation), patients may be either platinum-sensitive with no limit on prior regimens. Platinum-resistant patients are eligible but they may not have received more than 3 prior cytotoxic therapies since development of platinum resistance.
    • Cohort C and Cohort D, Part II, patients must be platinum-sensitive BUT with no limit to number of prior cytotoxic therapies. These patients must demonstrate adequate bone marrow function as determined by the treating physician.
  12. Prior treatment with a PARPi is permitted but not mandatory for Cohorts A and B and Cohort D Part I. Prior treatment with PARPi is mandatory for Cohort C and D Part II. If a patient has received a prior PARPi, then the patient must have demonstrated a clinical benefit of PARPi treatment by an initial response (by CA-125 or imaging) to PARPi treatment or clinical benefit from PARPi treatment as maintenance therapy followed by disease progression for enrollment. Clinical benefit for maintenance is defined as: a) prior maintenance with PARPi after 1st line chemotherapy of at least 12 months or b) prior maintenance with PARPi after >1 line of chemotherapy for minimum of 6 months.
