Eligibility Criteria Checklist

Specific guidelines that determine who can or cannot participate in a clinical trial

Must have

Patients must not have received prior exposure to other NTRK inhibitors including but not limited to LOXO-101 (larotrectinib), entrectinib (RXDX-101), DS6051, PLX7486

Bilirubin (sum of conjugated + unconjugated) =< 1.5 x upper limit of normal (ULN) for age (within 7 days prior to enrollment)

Must not have

Patients who are currently receiving drugs that are strong inducers or inhibitors of CYP3A4 are not eligible

Patients who are receiving cyclosporine, tacrolimus or other agents to prevent graft-versus-host disease (GVHD) post bone marrow transplant are not eligible for this trial

Summary

This trial is testing larotrectinib, which may stop the growth of cancer cells, in patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have spread and come back or do not respond to treatment.

Who is the study for?

This trial is for young patients aged 12 months to 21 years with advanced solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have NTRK fusions and are relapsed or refractory. They must not have used other NTRK inhibitors before, should be recovered from previous cancer treatments' side effects, and meet specific health criteria like adequate kidney function and blood counts.

What is being tested?

The study tests larotrectinib's effectiveness on various advanced cancers in youth with a genetic change called an NTRK fusion. It examines if this drug can halt cancer growth by blocking enzymes needed for cell proliferation. The trial includes imaging tests like MRI and CT scans to monitor the disease.

What are the potential side effects?

Larotrectinib may cause liver issues (elevated bilirubin), impact kidney function (creatinine clearance), affect blood cell counts leading to increased infection risk, fatigue, or other common chemotherapy-related side effects. Specific side effect profiles will be monitored closely.

1Treatment groups

Experimental Treatment

Group I: Treatment (larotrectinib sulfate)Experimental Treatment8 Interventions

Patients receive larotrectinib sulfate PO or via NG- or G-tube 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 CT scan, MRI, an x-ray, bone scan, and/or 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.
