Purpose

This phase II Pediatric MATCH trial studies how well larotrectinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with NTRK fusions that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and have come back (relpased) or does not respond to treatment (refractory). Larotrectinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

Detailed Description

PRIMARY OBJECTIVE: I. To determine the objective response rate (ORR; complete response + partial response) in pediatric patients treated with larotrectinib sulfate (LOXO-101 [larotrectinib]) with advanced solid tumors (including central nervous system [CNS] tumors), non-Hodgkin lymphomas or histiocytic disorders harboring NTRK 1/2/3 fusions. SECONDARY OBJECTIVES: I. To estimate the progression free survival in pediatric patients treated with LOXO-101 (larotrectinib) with advanced solid tumors (including CNS tumors), non-Hodgkin lymphomas or histiocytic disorders with NTRK 1/2/3 fusions. II. To obtain additional information about the tolerability of LOXO-101 (larotrectinib) in children with relapsed or refractory cancer. III. To provide preliminary estimates of the pharmacokinetics of LOXO-101 (larotrectinib) in children 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 larotrectinib sulfate orally (PO) or via nasogastric (NG)- or gastric (G)-tube twice per day (BID) on days 1-28. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo a computed tomography (CT) scan, magnetic resonance imaging (MRI), an x-ray, bone scan, and/or iobenguane (MIBG) scintigraphy during screening and on study. Patients also undergo bone marrow aspiration and/or biopsy during screening and may undergo blood sample collection on study. After completion of study treatment, patients are followed up at 30 days, then periodically thereafter.
