Brief Summary
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.

Tumor patients_Dose 5
EXPERIMENTALAdult patients with solid tumors receiving 150 mg of BAY2757556 twice daily (dose escalation cohort).
Tumor patients_Dose 6
EXPERIMENTALAdult patients with solid tumors receiving 200 mg of BAY2757556 twice daily (dose escalation cohort).
Tumor patients_Expansion
EXPERIMENTALAdults patients with solid tumors and neurotrophic tyrosine kinase (NTRK) genes or proteins of types 1 - 3 (dose expansion cohort). Patients receive either the recommended or maximum tolerated dose of BAY2757556 as determined in the dose escalation part.
Interventions
