Descriptive Information
Brief Title  ICMJE A Study to Test the Safety and Efficacy of the Drug Larotrectinib for the Treatment of Tumors With NTRK-fusion in Children
Official Title  ICMJE A Phase 1/2 Study of the Oral TRK Inhibitor LOXO-101 in Pediatric Patients With Advanced Solid or Primary Central Nervous System Tumors
Brief Summary

The study is being done to test the safety of a cancer drug called larotrectinib in children. The cancer must have a change in a particular gene (NTRK1, NTRK2 or NTRK3). Larotrectinib blocks the actions of these NTRK genes in cancer cells and can therefore be used to treat cancer.

The first study part (Phase 1) is done to determine what dose level of larotrectinib is safe for children, how the drug is absorbed and changed by their bodies and how well the cancer responds to the drug. The main purpose of the second study part (Phase 2) is to investigate how well and how long different cancer types respond to the treatment with larotrectininb.

Detailed Description

The primary objectives are to determine the safety and efficacy of oral larotrectinib in pediatric patients with advanced solid or primary central nervous system (CNS) tumors.

The secondary objectives comprise e.g. the determination of the pharmacokinetic properties, the maximum tolerated dose/ recommended dose and the tumor-type specific efficacy of larotrectinib. In addition, pain status and health-related quality of life of the pediatric patients will be assessed.
