About this study

Official title: 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.

Read the 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Absolute Oral Bioavailability for Quizartinib As Assessed By Pharmacokinetic Parameters for Area Under the Plasma Concentration-Time Curve Following Intravenous and Oral Administrations of Quizartinib

    The absolute bioavailability assessment for quizartinib was based on the pharmacokinetic parameters area under the curve (AUC) from the time of dosing to time Tlast (AUClast) and AUC from the time of dosing extrapolated to infinity (AUCinf) for quizartinib following intravenous and oral administrations. Pharmacokinetic parameters were calculated using a non-compartmental approach. PK parameters were computed using Phoenix™ WinNonlin® (Version 8.0).

    Measured: Relative to oral dosing: Pre-dose and at 1, 2, 4, 4.25, 4.5, 4.75, 5, 6, 8, 12, 24, 48, 72, 96, 144, 192, 240, 288, 336, 384, 432, 480, and 504 hours

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Quizartinib dihydrochloride and 14C-Quizartinib solution for infusion in people with Healthy Subjects, run by Daiichi Sankyo at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Jan 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Absolute Oral Bioavailability for Quizartinib As Assessed By Pharmacokinetic Parameters for Area Under the Plasma Concentration-Time Curve Following Intravenous and Oral Administrations of Quizartinib (time frame: Relative to oral dosing: Pre-dose and at 1, 2, 4, 4.25, 4.5, 4.75, 5, 6, 8, 12, 24, 48, 72, 96, 144, 192, 240, 288, 336, 384, 432, 480, and 504 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Jan 2023.
