This research study is done to test how well different types of cancer respond to the drug called larotrectinib. The cancer must have a change in a particular gene (NTRK1, NTRK2 or NTRK3). Larotrectinib is a drug that blocks the actions of these NTRK genes in cancer cells and can therefore be used to treat cancer.


The primary objective of this study is to investigate the efficacy of larotrectinib for the treatment of advanced solid tumors harboring a fusion of neurotrophic tyrosine receptor kinase (NTRK) of types 1-3 in children and adults.

Secondary objectives comprise the efficacy and safety of larotrectinib in different NTRK-tumor types.

Subjects must have at least one measurable lesion as defined by RECIST v1.1

Exclusion Criteria
