- 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
- Prior therapy must have been completed at least four weeks prior to registration
- Age >= 18
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0, 1 or 2

- Total bilirubin level =< 1.5 x institutional upper limit of normal (ULN) or =< 3 x ULN in the presence of documented Gilbert's syndrome (unconjugated hyperbilirubinemia) (within 14 days prior to registration)
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3 x ULN (within 14 days prior to registration)
- Patients must be able to swallow and retain oral medications and be without gastrointestinal illnesses that would preclude absorption of selumetinib or olaparib
- Patients with known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Functional Classification. To be eligible for this trial, patients should be class 2B or better
- Women of childbearing potential (WOCBP) must agree to use two forms of birth control (hormonal or barrier method of birth control; abstinence) during the study and for 6 months after completing treatment
- Non-sterilized male partners of WOCBP (including males sterilized by a method other than bilateral orchidectomy e.g., vasectomy) who intend to be sexually active with a female partner must be using an acceptable method of contraception such as male condom plus spermicide (condom alone in countries where spermicides are not approved) from the time of screening throughout the total duration of the study and the drug washout period (at least 6 months after the last dose of study intervention) to prevent pregnancy in a partner. 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
- Human immunodeficiency virus (HIV)-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months of registration 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
- The patient or a legally authorized representative must provide study-specific informed consent prior to study entry and, for patients treated in the United States (U.S.), authorization permitting release of personal health information
Who cannot join
- Patients who have received any MEK inhibitors

About this study
Official title: A Randomized Trial of Selumetinib and Olaparib or Selumetinib Alone in Patients With Recurrent or Persistent RAS Pathway Mutant Ovarian and Endometrial Cancers: A ComboMATCH Treatment Trial
This phase II ComboMATCH treatment trial compares selumetinib plus olaparib to selumetinib alone in women with endometrial or ovarian (fallopian tube and primary peritoneal) 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.
Read the detailed description
PRIMARY OBJECTIVES:
- 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)
SECONDARY OBJECTIVES:
- 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.
TRANSLATIONAL OBJECTIVE:
- 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) twice daily (BID) and olaparib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. 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 BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Progression-free survival
Disease progression will be defined using Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria, as determined by the treating physician. The primary analyses will be based on logrank tests stratified by the stratification factors as recorded at randomization. All enrolled patients will be included, regardless of compliance with their assigned study regimen. Patients will be grouped by their randomized treatment for intention-to-treat analyses. Treatment hazard ratios and 90% confidence intervals will be estimated using proportional hazards models specified with a main-effect for the randomized treatment assignment (experimental versus [vs] reference), and stratified using the stratification factors recorded at randomization. Treatment group differences will be graphed using Kaplan-Meier methods.
Measured: The duration of time from enrollment to the date of progression or death, whichever occurs first, assessed up to 5 years
Secondary outcomes (4)
Incidence of adverse events (AE)
The safety population will support these analyses. The nature, frequency, and degree of toxicity will be tabulated at the System Organ Class and AE-specific term levels using Common Terminology Criteria for Adverse Events v5.0. Each patient will be represented according to the maximum grade observed for each term. Tabulations will show the number and percentage of patients by maximum grade, within the treatment group received, regardless of the randomized treatment assignment.
Measured: Up to 5 years
Objective response rate (ORR) between two arms
ORR is defined as the binomial proportion of evaluable patients with a best overall response of complete response (CR) or partial response (PR) (by RECIST 1.1) within 6 months of the date of the last enrollment. Responses reported by the treating physician will be used for these analyses. The ORR estimates by treatment arm will be supported by their 2-sided, 95% Wilson-Score confidence intervals. The relative odds of response in the experimental arm (vs the reference arm) will be estimated using a multivariable logistic regression model specified with main effects for the randomized treatment assignment and covariate adjustments for the stratification factors reported at baseline.
Measured: Within 6 months of the date of last enrollment
ORR in crossover patients
Determined by RECIST 1.1. The crossover population will support these analyses. The same evaluation criteria for ORR in the measurable disease population will be applied to the crossover population. These analyses will be done separately for each cohort.
Measured: Up to 5 years
Duration of response of both arms
These analyses will be supported by patients in the measurable disease population who have a best overall response of PR or CR. Treatment group differences in response duration will be graphed using Kaplan-Meier methods and compared using logrank tests, stratified by the stratification factors defined at randomization. The relative hazards of progression or death in the experimental group (vs the reference group) will be estimated using a multivariable proportional hazards regression model specified with main effects for the treatment indicators and covariate adjustments for the stratification factors reported at baseline. These analyses will be done separately for each cohort.
Measured: The time from documentation of either PR or CR until disease progression or death, whichever is observed first, assessed up to 5 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Biopsy Procedure, Biospecimen Collection and Bone Marrow Aspiration and Biopsy in people with Recurrent Endometrial Carcinoma and Recurrent Fallopian Tube Carcinoma, run by National Cancer Institute (NCI) at 295 sites in 2 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 33 inclusion and 29 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 13 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 295 sites in United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
