Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This research study is done to test the safety of the drug larotrectinib in adult cancer patients. The drug may be used to treat cancer with a change in a particular gene (NTRK1, NTRK2 or NTRK3), because it blocks the action of these genes in cancer cells. The study also investigates how the drug is absorbed and processed in the human body. This is the first study to test larotrectinib in humans with cancer, for whom no other effective therapy exists.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial will be conducted in 2 parts: an initial dose escalation phase of larotrectinib in subjects with advanced solid tumors will be followed by an expansion phase in subjects with solid tumors having a NTRK fusion.

The objectives of the study are to determine the safety, pharmacokinetic profile, recommended dose and efficacy of orally administered larotrectinib in patients with NTRK fusions.
