Performance of the mandatory research biopsy or submission of pre-trial formalin-fixed paraffin-embedded (FFPE) and collection and submission of the blood specimens for the integrated studies will be performed under the consent authority of the specific treatment trial protocol to which the patient is registered. No procedures to collect specimens for research only are to be performed for patients registered to the EAY191 Registration Trial only

NOTE: Each ComboMATCH Treatment Trial contains specific eligibility criteria. If patient is found to not be eligible for the assigned ComboMATCH Treatment Trial, indication of ineligibility will trigger re-evaluation and potential assignment to another Treatment Trial

PRIMARY OBJECTIVE:
I. To register, allocate, and assign patients to ComboMATCH treatment trials.

SECONDARY OBJECTIVES:
I. To evaluate the rate of positive outcomes in defined cohorts within treatment trials of treatment combinations including targeted therapies for molecularly defined populations, and also in the subset of treatment trials where the treatments are supported by in vivo models.
II. To perform quality control of the patients registered in the form of pathological confirmation of disease and sub-type to confirm diagnosis and treatment arm allocation.

SECONDARY CORRELATIVE OBJECTIVES:
I. Assess the concordance of the central molecular characterization of the pre-treatment biopsy samples with the genetic readouts from the Designated Laboratories (DLs) for patients enrolled on the ComboMATCH treatment trials.
II. To assess how the registration diagnostic tumor mutation profile and pre-treatment biopsy profile compare to the circulating tumor-derived deoxyribonucleic acid (ctDNA) mutation profile from plasma. 

EXPLORATORY OBJECTIVE:
I. Assess association between ComboMATCH treatment trials outcomes (positive or negative) with the type of rationale for the selected drug combinations and the type of rationale for the gene variant/combination for selection (e.g., whether the trial was based on targeted therapies for molecularly defined populations, those that were supported by in vivo models, and those that were supported by empiric clinical data).

OUTLINE:
REGISTRATION: Patients undergo tumor mutational screening of previously-collected tumor samples for specific, pre-defined mutations, amplifications, or translocations of interest via tumor sequencing. Patients who are 18 years or older and have biopsiable disease undergo a new biopsy for research purposes prior to initiating treatment on the ComboMATCH treatment trial.

TREATMENT: Patients with mutations targeted to investigational combination therapies are assigned to 1 of 20 treatment subprotocols.

EAY191-N4: Patients with RAS pathway mutant ovarian or endometrial cancer 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 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 CT scans throughout the trial. Patients may undergo bone marrow aspiration or biopsy as clinically indicated.

EAY191-N2: Patients with NF1 nonsense or frameshift mutations or NF1 gene deletion, and hormone receptor positive, HER2-negative metastatic breast cancer. Patients who are fulvestrant naive are assigned to Cohort I, while patients who are fulvestrant resistant are assigned to Cohort II.

COHORT I: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive fulvestrant intramuscularly (IM) and binimetinib PO throughout the trial. Patients also undergo a CT, magnetic resonance imaging (MRI), or bone scan and tumor biopsy during screening and on study.

ARM II: Patients receive fulvestrant IM throughout the trial. Patients who progress on fulvestrant alone are asked to reaffirm their willingness to enroll in cohort II. Patients not willing to transition to cohort II continue further therapy as clinically indicated. Patients undergo a CT, MRI, or bone scan and tumor biopsy during screening and on study.

COHORT II: Patients receive fulvestrant IM and binimetinib PO throughout the trial. If the patient progressed on fulvestrant, the loading dose of fulvestrant is omitted. Patients undergo a CT, MRI, or bone scan and tumor biopsy during screening and on study.

Patients with LGSOC who have received prior MEK inhibitor therapy are assigned to combination cohort 2. Patients with KRAS/NRAS/HRAS/non-V600E BRAF mutated pancreatic cancer are assigned to combination cohort 3. Patients with all other KRAS/NRAS/HRAS mutated tumor types (excluding LGSOC, non-small cell lung cancer, colorectal cancer, pancreatic, and melanoma) are assigned to combination cohort 4.
