Targeted Therapy Directed by Genetic Testing in Treating Patients with Locally Advanced or Advanced Solid Tumors, The ComboMATCH Screening Trial

Summary

Objectives

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 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.
