Selpercatinib for the Treatment of Advanced Solid Tumors, Lymphomas, or Histiocytic Disorders With Activating RET Gene Alterations, a Pediatric MATCH Treatment Trial
NCI-COG Pediatric MATCH (Molecular Analysis for Therapy Choice) - Phase 2 Subprotocol of LOXO-292 in Patients With Tumors Harboring RET Gene Alterations
Sponsor: Children's Oncology Group
This observational or N/A phase trial investigates Hematopoietic and Lymphatic System Neoplasm and Recurrent Ependymoma and is currently ongoing. Children's Oncology Group leads this study, which shows 59 recorded versions since 2021 — indicating substantial longitudinal coverage. As an oncology study, it adds to the longitudinal record of treatment development for this indication.
Study Description(click to expand)PRIMARY OBJECTIVE:
I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with selpercatinib (LOXO-292) with advanced solid tumors (including central nervous system \[CNS\] tumors), lymphomas or histiocytic disorders that harbor activating genetic alterations in the RET pathway.
SECONDARY OBJECTIVES:
I. To estimate the progression free survival in pediatric patients treated with selpercatinib (LOXO-292) with advanced solid tumors (including CNS tumors), lymphomas or histiocytic disorders that harbor activating genetic alterations in the RET pathway.
II. To obtain information about the tolerability of selpercatinib (LOXO-292) in children and adolescents with relapsed or refractory cancer.
EXPLORATORY OBJECTIVE:
I. To explore approaches to profiling changes in tumor genomics over time through evaluation of circulating tumor deoxyribonucleic acid (DNA).
OUTLINE:
Patients receive selpercatinib orally (PO) twice daily (BID) on days 1-28 on study. Treatment repeats every 28 days for up to 26 cycles (2 years) in the absence of disease progression or unacceptable toxicity. Patients may also undergo positron emission tomography (PET), computed tomography (CT), magnetic resonance imaging (MRI), PET/CT, PET/MRI, and/or CT/MRI, scintigraphy, and x-ray imaging throughout the trial.
After completion of study treatment, patients are followed for 30 days, then periodically thereafter.

Eligibility Summary
This phase II pediatric MATCH treatment trial studies how well selpercatinib works in treating patients with solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced), lymphomas, or histiocytic disorders that have activating RET gene alterations. Selpercatinib may block the growth of cancer cells that have specific genetic changes in an important signaling pathway (called the RET pathway) and may reduce tumor size.
