A Rolling-6 dose escalation design will be used. The starting dose for participants age \< 12 years will be 25% below the highest dose level cohort divided by 1.73 m\^2 cleared by the Safety Review Committee (SRC) for subjects age 12 years and older.

A 3+3 dose escalation design will be used to determine the maximum tolerated dose (MTD)/recommended dose for further study, enrolling 3 to 6 participants per cohort with a starting dose level of 100 mg twice daily (BID).

Selitrectinib is administered as capsules or liquid formulation.

Selitrectinib (BAY2731954)

This research study is done to test the safety of the new drug selitrectinib in children and adults with cancer having a change in a particular gene (NTRK1, NTRK2 or NTRK3). The drug may treat cancer by interfering with the effect of the NTRK genes on cancer growth. The study also investigates how the drug is absorbed and processed in the human body, and how well and for how long the cancer responds to the drug. This is the first study to test selitrectinib in humans with cancer, for whom no other effective therapy exists.

The primary objective is to determine the recommended dose for further study of oral selitrectinib with previously treated neurotrophic tyrosine kinase (NTRK) cancers in 2 patient groups: a) aged 12 years and older and b) younger than 12 years. Secondary objectives of Phase I are to characterize the pharmakokinetic properties of the test drug, its safety and tolerability, and to assess the objective response rate (ORR) of NTRK-tumors.

A Phase 1 Study of the TRK Inhibitor Selitrectinib (BAY 2731954) in Adult and Pediatric Subjects With Previously Treated NTRK Fusion Cancers

Availability of this study's data will later be determined according to Bayer's commitment to the EFPIA/PhRMA "Principles for responsible clinical trial data sharing". This pertains to scope, timepoint and process of data access. As such, Bayer commits to sharing upon request from qualified researchers patient-level clinical trial data, study-level clinical trial data, and protocols from clinical trials in patients for medicines and indications approved in the US and EU as necessary for conducting legitimate research. This applies to data on new medicines and indications that have been approved by the EU and US regulatory agencies on or after January 01, 2014.

Severity is assessed using CTCAE version 4.03

ORR is determined by the investigator using the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.

ORR is determined by the treating investigator using the Response Assessment in Neuro-Oncology (RANO) criteria.

Healthy male participants receive a single dose of 25 mg selitrectinib (Period 1) and 75 mg selitrectinib (Period 2) in fasted state.

Healthy male participants receive a single dose of 50 mg selitrectinib in fasted state (Period 1) and 50 mg selitrectinib in fed state (Period 2).

Healthy male participants receive a single dose of 100 mg selitrectinib (Period 1) and 150 mg selitrectinib (Period 2) in fasted state.

Selitrectinib is administered orally as liquid suspension (20 mg/mL) on Day 1 of each period. Each period lasts 4 days, both periods of each arm are separated by at least 3 days.

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.

The primary objectives of this study are to investigate the pharmacokinetics and the effect of food on the pharmacokinetics of selitrectinib after a single dose of the drug.

Secondary objective is to assess the safety of selitrectinib after a single dose.

Selitrectinib expanded access is for minor and adult patients with cancer having a change in a particular gene (NTRK1, NTRK2, or NTRK3 gene fusion). The patients are ineligible for an ongoing selitrectinib clinical trial or have other considerations that prevent access to selitrectinib through an existing clinical trial. Expanded access is intended to treat individual patients with different types of cancers with a NTRK gene fusion, including blood cancers, who have previously received tropomyosin receptor kinase (TRK) inhibitor therapy.
