 (submitted: July 10, 2017)
Progression free survival [ Time Frame: The time from the initiation of protocol treatment to the occurrence of any of the following events: disease progression or disease recurrence or death from any cause, assessed up to 5 years ]
Progression free survival along with the confidence intervals will be estimated using the Kaplan-Meier method. Patients with local calls of disease progression (i.e. calls made by the treating institution), will be counted as having had an event, even if the central review does not declare progression. Progression free survival will be reported based on central radiology review as a secondary analysis, if adequate number of disagreements in progressions exist between the treating institutions and the central radiology review to make such an analysis meaningful.
Original Secondary Outcome Measures  ICMJE Same as current
Current Other Pre-specified Outcome Measures
 (submitted: April 18, 2019)
  • Incidence of adverse events [ Time Frame: Up to 5 years ]
    Toxicity tables will be constructed to summarize the observed incidence by type of toxicity and grade. A patient will be counted only once for a given toxicity for the worst grade of that toxicity reported for that patient. Toxicity information recorded will include the type, severity, time of onset, time of resolution, and the probable association with the study regimen.
  • Pharmacokinetics of larotrectinib [ Time Frame: Pre-dose, 1, 2, 4, and 6-8 hours after morning dose of day 1 cycle 1 and pre-dose of day 1 cycle 2 ]
    A descriptive analysis of pharmacokinetic parameters of LOXO-101 (larotrectinib) will be performed to define systemic exposure, drug clearance, and other pharmacokinetic parameters. The pharmacokinetic parameters will be summarized with simple summary statistics, including means, medians, ranges, and standard deviations (if numbers and distribution permit). All these analyses will be descriptive and exploratory and hypotheses generating in nature.
  • Ability to detect NTRK fusions in circulating cell-free tumor deoxyribonucleic acid in plasma [ Time Frame: Up to 5 years ]
    A descriptive analysis of the exploratory aims will be performed and will be summarized with simple summary statistics. All of these analyses will be descriptive in nature.

Brief Title  ICMJE Larotrectinib in Treating Patients With Relapsed or Refractory Advanced Solid Tumors, Non-Hodgkin Lymphoma, or Histiocytic Disorders With NTRK Fusions (A Pediatric MATCH Treatment Trial)
Official Title  ICMJE NCI-COG Pediatric MATCH (Molecular Analysis for Therapy Choice) - Phase 2 Subprotocol of LOXO-101 (Larotrectinib) in Patients With Tumors Harboring Actionable NTRK Fusions
Brief Summary 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 have spread to other places in the body and have come back or do not respond to treatment. 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 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.

After completion of study treatment, patients are followed up at 30 days, then periodically thereafter.
