Ulixertinib in Treating Patients With Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With MAPK Pathway Mutations (A Pediatric MATCH Treatment Trial)

NCI-COG Pediatric MATCH (Molecular Analysis for Therapy Choice) - Phase 2 Subprotocol of BVD-523FB (Ulixertinib) in Patients With Tumors Harboring Activating MAPK Pathway Mutations

This phase II Pediatric MATCH trial studies how well ulixertinib works in treating patients with solid tumors that have spread to other places in the body (advanced), non-Hodgkin lymphoma, or histiocytic disorders that have a genetic alteration (mutation) in a signaling pathway called MAPK. A signaling pathway consists of a group of molecules in a cell that control one or more cell functions. Genes in the MAPK pathway are frequently mutated in many types of cancers. Ulixertinib may stop the growth of cancer cells that have mutations in the MAPK pathway.

Detailed Description

PRIMARY OBJECTIVES:

I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with BVD-523FB (ulixertinib) with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor activating genetic alterations in the MAPK pathway.

SECONDARY OBJECTIVES:

I. To estimate the progression free survival in pediatric patients treated with BVD-523FB (ulixertinib) with advanced solid tumors (including CNS tumors), non-Hodgkin lymphomas or histiocytic disorders that harbor activating genetic alterations in the MAPK pathway.

II. To obtain information about the tolerability of BVD-523FB (ulixertinib) in children and adolescents with relapsed or refractory cancer.

III. To provide preliminary estimates of the pharmacokinetics of BVD-523FB (ulixertinib) in children and adolescents with relapsed or refractory cancer.

EXPLORATORY OBJECTIVES:

I. To evaluate other biomarkers as predictors of response to BVD-523FB (ulixertinib) and specifically, whether tumors that harbor different mutations or fusions will demonstrate differential response to BVD-523FB (ulixertinib) treatment.

II. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).

OUTLINE: This is a dose-escalation study.

Patients receive ulixertinib orally (PO) twice daily (BID). Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.
