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

November 28, 2018 updated by: Cascadian Therapeutics Inc.

A Phase 1, Open-label Study of the Absorption, Metabolism, and Excretion of [¹⁴C]-Tucatinib Following a Single Oral Dose in Healthy Male and Female Subjects

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
