Ovarian Cancer Clinical Trial
Testing the Use of the Combination of Selumetinib and Olaparib or Selumetinib Alone Targeted Treatment for RAS Pathway Mutant Recurrent or Persistent Ovarian and Endometrial Cancers, A ComboMATCH Treatment Trial
This phase II trial compares selumetinib plus olaparib to selumetinib alone in women with endometrial or ovarian cancer that has come back (recurrent) or that remains despite treatment (persistent) and harbors a mutation in the RAS pathway. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. The addition of olaparib to selumetinib could increase the percentage of tumors that shrink as well as lengthen the time that the tumors remain stable (without progression) as compared to selumetinib alone.
I. Compare progression free survival of combination of olaparib and selumetinib sulfate (selumetinib) to selumetinib alone in patients with RAS mutant ovarian cancer. (Cohort 1) II. Compare progression free survival of combination of olaparib and selumetinib to selumetinib alone in patients with RAS mutant endometrial cancer. (Cohort 2)
I. Determine safety of both arms per Common Terminology Criteria for Adverse Events (CTCAE) version (v)5.0.
II. Compare objective response rate per Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 between the two arms.
III. Determine rate of objective response per RECIST 1.1 in those patients that crossover from the single agent arm to the combination arm.
IV. Report duration of response of the two treatment arms. V. Collect tissue and provide it to the ComboMATCH Registration protocol to assess concordance between the diagnostic tumor mutation profile generated by the designated laboratories, the pre-treatment biopsy mutation profile, and the pre-treatment circulating tumor (ct)DNA mutation profile from plasma, as described in ComboMATCH Registration protocol. For this treatment substudy, the outcome objective will be to report the proportion of cases providing sufficient tissue for that integrated scientific activity in the ComboMATCH Registration protocol.
I. To assess association of baseline genomic and transcriptomic status with response and resistance to therapy.
OUTLINE: Patients in both cohorts are randomized to 1 of 2 arms.
ARM I: Patients receive selumetinib orally (PO) and olaparib PO on study. Patients also undergo a tumor biopsy and blood collection during screening and on study, as well as echocardiogram (ECHO) or multigated acquisition (MUGA), and computed tomography (CT) scans throughout the trial. Patients may undergo bone marrow aspiration or biopsy as clinically indicated.
ARM II: Patients receive selumetinib PO on study. Patients who experience progression may elect to cross over to Arm I provided they have not had dose limiting toxicities to monotherapy selumetinib. Patients also undergo a tumor biopsy and blood collection during screening and on study, as well as ECHO or MUGA, and CT scans throughout the trial. Patients may undergo bone marrow aspiration or biopsy as clinically indicated.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
Patient must have enrolled onto EAY191 and must have been given a treatment assignment to ComboMATCH to EAY191-N4 based on the presence of an actionable mutation as defined in EAY191
Patients must be enrolled on the ComboMATCH Master Registration Trial EAY191
Patients must have RAS pathway mutations as determined by the ComboMATCH screening assessment
Cohort 1: Patients with histologically confirmed RAS pathway mutant ovarian, primary peritoneal, or fallopian tube ("ovarian") cancer (activating mutations in KRAS, NRAS, HRAS, BRAF, MEK1, MEK2, or inactivating mutations in NF1)
Cohort 2: Patients with histologically confirmed RAS pathway mutant endometrial cancer (activating mutations in KRAS, NRAS, HRAS, BRAF, MEK1, MEK2, or inactivating mutations in NF1).
Patients must have disease that can be safely biopsied and agree to a pre-treatment biopsy, if disease cannot be safely biopsied, or have archival tissue available from within 12 months prior to registration on the ComboMATCH Registration Trial (EAY191)
Patients must have progressed after first-line treatment for recurrent or persistent disease
Patients with ovarian cancer should not be eligible for further platinum-based therapy
Patients with endometrial cancer must have received or been offered an immune oncology agent (alone or in combination with lenvatinib) unless there are existing contraindications for immune oncology agents or lenvatinib
Patients may have received unlimited prior therapy
Patients must have measurable and biopsiable disease. Measurable disease is defined by RECIST 1.1 as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be > 10 mm when measured by CT, magnetic resonance imaging (MRI) or caliper measurement by clinical exam; or > 20 mm when measured by chest x-ray. Lymph nodes must be > 15 mm in short axis when measured by CT or MRI
Patients must have at least one "target lesion" separate from the lesion to be biopsied to be used to assess response on this protocol as defined by RECIST version 1.1. Tumors within a previously irradiated field will be designated as "non-target" lesions unless progression is documented or a biopsy is obtained to confirm persistence at least 90 days following completion of radiation therapy

Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of contraception. Vasectomized (i.e., sterile) males are considered fertile and should still use a male condom plus spermicide as indicated above during the clinical study
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

Patients with evidence of chronic hepatitis B virus (HBV) infection must have an undetectable HBV viral load on suppressive therapy, if indicated
Patients with a history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable HCV viral load
Patients with new or progressive brain metastases (active brain metastases) or leptomeningeal disease are eligible if the treating physician determines that immediate central nervous system (CNS) specific treatment is not required and is unlikely to be required during the first cycle of therapy
Patients with treated brain metastases are eligible if follow-up brain imaging after CNS-directed therapy shows no evidence of progression
Extra caution should be taken with olaparib, as it crosses the blood brain barrier and can cause edema in brain metastases
