Ovarian Cancer Clinical Trial

Combination ATR and PARP Inhibitor (CAPRI) Trial With AZD6738 and Olaparib in Recurrent Ovarian Cancer

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 AZD6738 and Olaparib in women with recurrent ovarian cancer in distinct platinum-sensitive and platinum-resistant cohorts.

Eligibility Criteria

Inclusion criteria:

For inclusion in the study, patients must fulfill the following criteria:

Patients ≥ 18 years of age
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 and a life expectancy of at least 6 months.
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 histologies 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.
All patients under consideration for Cohorts A, B, C, and D, 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, 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 who undergo attempted biopsies that are unsuccessful may still enroll and receive study drug.
All patients must have a measurable disease by RECIST v1.1.

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 study review committee or University of Pennsylvania principal investigator.
Cohort D Part I: Patients will be enrolled irrespective of BRCA status.
Adequate renal function, defined as measured creatinine clearance ≥ 51 ml/min.
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.
Adequate bone marrow function, defined as absolute neutrophil count (ANC ≥ 1.5 X 109/L), platelet count ≥ 100 x 109/L, and hemoglobin ≥ 10 g/dL (in the absence of transfusion within 28 days prior to dosing).
Patients must be at least 2 weeks from previous therapy for their ovarian cancer (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. Hormones for breast cancer management may be continued at the discretion of the provider.

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.

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 onto Cohort C and D Part II. Clinical benefit for maintenance is defined as:

prior maintenance with PARPi after 1st line chemotherapy of at least 12 months or
prior maintenance with PARPi after >1 line of chemotherapy for minimum of 6 months. Subjects on Cohort A may have received treatment with PARPi, clinically benefitted, but not have progressed on a PARPi. This arm is to evaluate participants who have received prior PARPi (PARPi after PARPi).

If the prior PARP inhibitor used was olaparib, it must have been tolerated without dose reduction for hematological toxicities. Olaparib must have been tolerated at a dose of 300mg twice daily for Arms A, B, & C. Olaparib must have been tolerated at a dose of 200 mg twice daily or higher for Arm D.

For Cohort C and D Part II, patients may not have received cytotoxic chemotherapy in the interval between PARPi monotherapy and enrollment.

Patients who have had major surgery (as defined by the Site PI) must be fully recovered and ≥4 weeks post-operative prior to enrolling on study.
Patients must be able to swallow oral medications (capsules and tablets) without chewing, breaking, crushing, opening, or otherwise altering the product formulation. They should not have gastrointestinal illnesses that would preclude the absorption of AZD6738 or olaparib, which are oral agents.

Postmenopausal defined as:

Amenorrhea for 1 year or more following cessation of exogenous hormonal treatments;
LH and FSH levels in post-menopausal range for women under 50;
Radiation induced oophorectomy with last menses >1 year ago;
Chemotherapy-induced menopause with >1 yr interval since last menses;
Surgical sterilization (bilateral oophorectomy or hysterectomy).
Able to understand and voluntarily sign a written informed consent, and are willing and able to adhere to the protocol requirements.
Patients with a history of brain metastases diagnosed greater than one year prior to study entry may be considered if they received sterilizing therapy to the CNS (resection or radiation) and have been CNS recurrence-free for the one-year period.

Exclusion criteria:

Patients with known brain metastases diagnosed within one year will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
Patients who have had prior AZD6738 or other cell cycle checkpoint inhibitors such as other ATM or ATR inhibitor, WEE-1 inhibitor, or CHK1 (or 1/2) inhibitors.
Patients with a serious cardiac condition, such as congestive heart failure; New York Heart Association Class III/IV heart disease; unstable angina pectoris; myocardial infarction within the last 3 months; valvulopathy that is severe, moderate, or deemed clinically significant; or arrhythmias that are symptomatic or require treatment. Resting ECG with QTc > 470 msec on two or more time points within a 24-hour period or family history of long QT syndrome.
Patients with a systolic blood pressure <90 mm Hg at two consecutive visits or recurrent symptomatic orthostatic hypotension.
Lack of recovery of prior adverse events due to prior cancer therapy to Grade ≤1 (NCI CTCAE v5.0; except alopecia). Stable persistent Grade 2 peripheral neuropathy may be allowed as determined on a case-by-case basis at the discretion of the PI. Patients with platinum-related hypomagnesemia (on replacement) will be eligible.
Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, clinically significant GI bleeding or hemoptysis within 28 days prior to the start of the study, or psychiatric illness/social situations that would limit compliance with study requirements.
Another previous, active or current invasive malignancy within the last five years, with the exception of curatively treated stage IA cervical carcinoma, or resected stage IA, Grade 1 endometrial cancer, noninvasive non-melanoma skin cancers, DCIS of the breast or other solid tumors including lymphomas (without bone marrow involvement). Patients with localized breast cancer who are disease free at least three years out from treatment may be eligible.
Immunocompromised patients or HIV-positive patients on HAART due to potential drug interaction.
Concomitant use of known strong CYP3A inhibitors (e.g. itraconazole, telithromycin, clarithromycin, protease inhibitors boosted with ritonavir or cobicistat, indinavir, saquinavir, nelfinavir, boceprevir, telaprevir) or moderate CYP3A inhibitors (e.g. ciprofloxacin, erythromycin, diltiazem, fluconazole, verapamil). The required washout period prior to starting olaparib is two weeks.
Concomitant use of known strong (e.g. phenobarbital, enzalutamide, phenytoin, rifampicin, rifabutin, rifapentine, carbamazepine, nevirapine and St John's Wort) or moderate CYP3A inducers (e.g. bosentan, efavirenz, modafinil). The required washout period prior to starting olaparib is five weeks for enzalutamide or phenobarbital and three weeks for other agents.
Patients with myelodysplastic syndrome, acute myeloid leukemia, or with features suggestive of MDS/AML.
Major surgery within four weeks of starting study.
Patients with a known hypersensitivity to AZD6738 or olaparib or any of the excipients of the product.
Platinum refractory (progress in first line platinum therapy) are excluded for Cohorts A, B, C, D PART II.
Patients receiving any systemic chemotherapy or radiotherapy (except for palliative reasons) within three weeks prior to study treatment.
Patients with known active hepatitis (i.e. Hepatitis B or C) due to risk of transmitting the infection through blood and other body fluids.
Previous allogeneic bone marrow transplant or double umbilical cord blood transplantation (dUCBT).
Whole blood transfusions in the last 120 days prior to entry to the study.
