A Study to Test the Safety and Efficacy of the Drug Larotrectinib for the Treatment of Tumors With NTRK-fusion in Children

Phase 1
Active, not recruiting
Conditions
Solid Tumors Harboring NTRK Fusion
Interventions
Registration Number
NCT02637687
Lead Sponsor
Bayer
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.

Inclusion Criteria
  • Phase 1 (Closed):

    • Dose escalation: Birth through 21 years of age at C1D1 with a locally advanced or metastatic solid tumor or primary CNS tumor that has relapsed, progressed or was nonresponsive to available therapies and for which no standard or available systemic curative therapy exists; OR Infants from birth and older with a diagnosis of malignancy and with a documented NTRK fusion that has progressed or was nonresponsive to available therapies, and for which no standard or available curative therapy exists; OR Patients with locally advanced infantile fibrosarcoma who would require, in the opinion of the investigator, disfiguring surgery or limb amputation to achieve a complete surgical resection. Phase I dose escalation cohorts are closed to enrollment.

Patients with NTRK-fusion positive benign tumors are also eligible; OR Potential patients older than 21 years of age with a tumor diagnosis with histology typical of a pediatric patient and an NTRK fusion may be considered for enrollment following discussion between the local site Investigator and the Sponsor.
