Description:
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.

Purpose
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
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.
