About this study

Official title: NCI-COG Pediatric MATCH (Molecular Analysis for Therapy Choice) - Phase 2 Subprotocol of LOXO-101 (Larotrectinib) in Patients With Tumors Harboring Actionable NTRK Fusions

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 (relapased) 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.

Read the detailed description

PRIMARY OBJECTIVE:

  1. 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:

  1. 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:

  1. 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Response Rate

    A responder is defined as a patient who achieves a best response of partial response or complete response on the study. Response rates will be calculated as the percent of evaluable patients who are responders. The revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1) was used to determine response and progression in this study, with specific criteria outlined for the different subtypes of tumors (e.g., 2-dimensional measurements for central nervous system (CNS) tumors).

    Measured: Up to 2 years from study entry

Secondary outcomes (2)

  1. Progression Free Survival (PFS)

    The Kaplan-Meier method will be used to estimate the 6 month PFS. PFS is defined as time from initiation of protocol treatment to disease progression, recurrence, death from any cause, or date of last contact.

    Measured: Up to 6 months from study entry

  2. Percentage of Patients Experiencing Grade 3 or Higher Adverse Events

    Percentage of patients experiencing grade 3 or higher adverse events will be evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0.

    Measured: Up to 2 years from study entry

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (time frame: Up to 2 years from study entry). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03213704.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jun 2026.
