A Study to Determine the Absolute Oral Bioavailability of Quizartinib Using a Radiolabeled Microtracer in Healthy Subjects

April 15, 2022 updated by: Daiichi Sankyo, Inc.

An Open Label Study to Determine the Absolute Oral Bioavailability of Quizartinib Using a Radiolabeled Microtracer in Healthy Subjects

Quizartinib, a selective FLT3 inhibitor, is being developed as a treatment for acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). The absolute oral bioavailability of quizartinib has not yet been studied. This study is designed to estimate quizartinib bioavailability of quizartinib following oral and intravenous (IV) administration.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Quizartinib bioavailability based on the dose-adjusted exposure of quizartinib following oral and IV administration will be assessed in healthy male subjects. The primary objective of this study is to determine the absolute oral bioavailability of quizartinib. Secondary objectives will include characterizing the plasma PK of quizartinib, radiolabeled quizartinib, and the major circulating metabolite after a single oral dose and IV administration. Safety and tolerability of quizartinib will also be assessed.

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.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study
