Ovarian Cancer Clinical Trial
Testing the Addition of an Immunotherapy Drug, Tremelimumab, to the PARP Inhibition Drug, Olaparib, for Recurrent Ovarian, Fallopian Tube or Peritoneal Cancer
This phase II trial studies how well olaparib with or without tremelimumab works in treating patients with ovarian, fallopian tube, or peritoneal cancer that has come back (recurrent). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Immunotherapy with monoclonal antibodies, such as tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving olaparib and tremelimumab together may work better than olaparib alone in treating patients with ovarian, fallopian tube, or peritoneal cancer.
I. To determine whether olaparib plus tremelimumab has adequate safety in the study population. (Safety Lead-in Trial Components) II. To compare the progression-free survival (PFS) duration of olaparib monotherapy versus olaparib plus tremelimumab in women with recurrent, platinum sensitive ovarian, primary peritoneal, or fallopian tube cancer. (Phase II Trial Component)
I. To compare the overall response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 in women with recurrent, platinum sensitive ovarian, primary peritoneal or fallopian tube cancer treated with either olaparib monotherapy or olaparib plus tremelimumab.
II. To compare the overall survival (OS) of women with recurrent, platinum sensitive ovarian, primary peritoneal or fallopian tube cancer treated with either olaparib monotherapy or olaparib plus tremelimumab.
I. To explore whether conditions in the tumor microenvironment (as measured by gene expression signature in archived tumor samples) identify patients that benefit from combined olaparib and tremelimumab immunotherapy.
II. To explore whether mutations in BRCA1/2 genes or other evidence of homologous repair deficiency (HRD+) is prognostic and/or predictive of response to combined olaparib and tremelimumab immunotherapy.
III. To explore associations between PD1 expression in the tumor microenvironment and outcome and changes in circulating leukocyte populations.
IV. To explore the correlation between tumor mutational burden and response to olaparib and tremelimumab immunotherapy.
V. To explore the impact of olaparib and tremelimumab versus olaparib monotherapy on circulating leukocyte subsets via exploration of the immunomodulatory effects of PARP inhibition and the added impact of CTLA4 blockade in this patient population.
VI. To explore cytokine/chemokine levels using a multiplex immunoassay (Olink) and correlate these levels with clinical endpoints.
VII. To use cell-free deoxyribonucleic acid (DNA) to assess BRCA mutation status as a mechanism of acquired resistance to prior PARP inhibition and to compare with treatment efficacy.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive olaparib orally (PO) twice daily (BID) in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI) as well as blood sample collection throughout the trial.
ARM II: Patients receive olaparib as in Arm I. Patients also receive tremelimumab intravenously (IV) over 60 minutes on day 1. Cycles of tremelimumab repeat every 4 weeks for 4 doses and then every 12 weeks for up to 2 years total in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI as well as blood sample collection throughout the trial.
After completion of study treatment, patients are followed up monthly for 3 months, then every 3 months for 2 years, followed by every 6 months for 3 years.
Patients must have platinum-sensitive, recurrent high-grade serous or high-grade endometrioid (grade 3) ovarian, primary peritoneal, or fallopian tube cancer. Patients with other histologies are also eligible, provided that the patient has a known deleterious germline or somatic BRCA1 or BRCA2 mutation identified through testing at a clinical laboratory. Submission of BRCA testing results (germline and/or somatic) is required for all patients.
Platinum-sensitive disease defined as no clinical or radiographic evidence of disease recurrence for > 6 months (or 182 days) after last receipt of platinum-based therapy. The date should be calculated from the last administered dose of platinum 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.
Patients must have RECIST 1.1 measurable disease. Patients with biochemical recurrence based on CA125 levels alone are not eligible.
Prior chemotherapy must have included a first-line platinum-based regimen with or without consolidation chemotherapy.
Prior bevacizumab therapy as a component of frontline or recurrent treatment is permitted.
Patients may have received an unlimited number of platinum-based therapies in the recurrent setting.
Patients may have received up to one non-platinum-based line of therapy in the recurrent setting. Prior hormonal therapy will not be counted as this non-platinum-based line.
Prior treatment with a PARP inhibitor:
Patients may not have had a prior PARP inhibitor in the recurrent setting.
Prior use of a PARP inhibitor in the upfront maintenance setting is allowed for women with a confirmed BRCA1 or BRCA2 germline or somatic mutation.
Women who received a PARP inhibitor for maintenance therapy in the frontline setting must have received at least one other chemotherapy regimen for recurrence prior to enrolling on this trial.
Patients who demonstrated disease progression while on a PARP inhibitor are excluded.
