Trial Purpose

The researchers in this study want to gather information in healthy adult male participants about how the human body absorbs, distributes and excretes the drug selitrectinib including the effect of the interaction of food with the study drug on the human body. Selitrectinib is a new drug under development for the treatment of patients with solid tumor caused by a genetic abnormality known as an NTRK gene fusion which cannot be cured by currently available treatment options or has spread to other parts of the body. The drug blocks the action of the NTRK gene fusion and prevents the activation of certain proteins (TRK fusion proteins), which can cause cancer cells to multiply and form a tumor. Researchers also want to find out if the participants have any medical problems during this study.
Participants in this study will receive the study drug twice with at least 6 days in between. The study drug will be taken orally as a liquid before or after meal. Observation will last for up to 8 weeks, and blood samples will be taken from the participants to measure the blood levels of the study drug.
