Trial summary

This phase II MATCH treatment trial tests how well larotrectinib (LOXO-101) works in treating patients with cancer that has certain genetic changes. Larotrectinib (LOXO-101) is used in patients whose cancer has a mutated (changed) form of a gene called NTRK. It is in a class of medications called kinase inhibitors. Read more about this study

About this study

Official title: MATCH Treatment Subprotocol Z1E: Larotrectinib (LOXO-101) in Patients With Tumors With NTRK Fusions

This phase II MATCH treatment trial tests how well larotrectinib (LOXO-101) works in treating patients with cancer that has certain genetic changes. Larotrectinib (LOXO-101) is used in patients whose cancer has a mutated (changed) form of a gene called NTRK. It is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To evaluate the proportion of patients with objective response (OR) to targeted study agent(s) in patients with advanced refractory cancers/lymphomas/multiple myeloma.

SECONDARY OBJECTIVES:

  1. To evaluate the proportion of patients alive and progression free at 6 months of treatment with targeted study agent in patients with advanced refractory cancers/lymphomas/multiple myeloma.

II. To evaluate time until death or disease progression. III. To identify potential predictive biomarkers beyond the genomic alteration by which treatment is assigned or resistance mechanisms using additional genomic, ribonucleic acid (RNA), protein and imaging-based assessment platforms.

IV. To assess whether radiomic phenotypes obtained from pre-treatment imaging and changes from pre- through post-therapy imaging can predict objective response and progression free survival and to evaluate the association between pre-treatment radiomic phenotypes and targeted gene mutation patterns of tumor biopsy specimens.

OUTLINE:

Patients receive larotrectinib (LOXO-101) orally (PO) twice daily (BID) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo computed tomography (CT) or magnetic resonance imaging (MRI) during screening and on study, as well as during follow-up as clinically necessary. Patients also undergo biopsies and blood sample collection on study.

After completion of study treatment, patients are followed every 3 months for 2 years and then every 6 months for 1 year.

Please see NCT02465060 for information on the MATCH Screening Protocol and applicable documents.

What is being measured

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

  1. Objective Response Rate (ORR)

    ORR is defined as the percentage of patients whose tumors have a complete or partial response to treatment among analyzable patients. Objective response is defined consistent with Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Details about how to define complete response and partial response can be found in the master protocol. 90% two-sided binomial exact confidence interval is calculated for ORR.

    Measured: Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

Secondary outcomes (2)

  1. 6-month Progression Free Survival (PFS)

    Progression free survival is defined as time from treatment start date to date of progression or death from any cause, whichever occurs first. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression. 6 month PFS rate was estimated using the Kaplan-Meier method, which can provide a point estimate for any specific time point.

    Measured: Assessed at baseline, then every 2 cycles for the first 26 cycles, and every 3 cycles thereafter until disease progression, up to 3 years post registration, from which 6-month PFS rate is determined

  2. Progression Free Survival

    PFS was defined as time from treatment start date to date of disease progression or death from any causes, whichever occurred first. Median PFS was estimated using the Kaplan-Meier method. Disease progression was evaluated using the Response Evaluation Criteria in Solid Tumors version 1.1, the Cheson (2014) criteria for lymphoma patients, and the Response Assessment in Neuro-Oncology criteria for glioblastoma patients. Please refer to the protocol for detailed definitions of disease progression.

    Measured: Assessed at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Biopsy Procedure, Biospecimen Collection and Computed Tomography in people with Advanced Lymphoma and Advanced Malignant Solid Neoplasm, run by National Cancer Institute (NCI) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 5 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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 11 Aug 2026). 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 (ORR) (time frame: Tumor assessments occurred at baseline, then every 2 cycles for the first 26 cycles and every 3 cycles thereafter until disease progression, up to 3 years post registration). 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 NCT06390852.

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 5 Nov 2026.
