A Study of the Absorption, Metabolism, and Excretion of Tucatinib in Healthy Participants

Phase 1
Completed
Conditions
Healthy
Interventions
Registration Number
NCT03758339
Lead Sponsor
Cascadian Therapeutics Inc.
Brief Summary

This study will look at how a drug (tucatinib) leaves the body and what happens to tucatinib while it is still in the body. Healthy participants will get one dose of tucatinib by mouth. Patients will be monitored for 8-14 days after they take the dose of tucatinib.

Detailed Description

This study will examine the absorption, metabolism, and excretion of tucatinib in healthy individuals. Participants will receive one oral dose of tucatinib and will be followed for 8-14 days after the dose is received.
