Trial summary

This research study is looking at how imatinib affects how dasatinib is absorbed and eliminated from the body. Both imatinib and dasatinib are in a class of medications called tyrosine kinase inhibitors (TKI) and they are used to treat certain types of leukemia (cancer that begins in the white blood cells).

About this study

Official title: Explore the Synergy of Combination TKI Therapy - A Pilot Study to Evaluate the Effect of Imatinib on Dasatinib Pharmacokinetics in Healthy Volunteers

This research study is looking at how imatinib affects how dasatinib is absorbed and eliminated from the body. Both imatinib and dasatinib are in a class of medications called tyrosine kinase inhibitors (TKI) and they are used to treat certain types of leukemia (cancer that begins in the white blood cells). Both imatinib and dasatinib have been given safely in healthy volunteers. In this study investigators will evaluate the pharmacokinetics interaction between imatinib and dasatinib when they are co-administered. The hypothesis is that imatinib will increase the blood levels of dasatinib through inhibiting the drug metabolizing enzyme and efflux transporter that are involved in the dasatinib absorption and removal. This research will provide important new insight of combination TKI therapy in terms of transporter- and enzyme- mediated pharmacokinetic interactions. The research results will also help guide doctors in knowing how much of a tyrosine kinase inhibitor to give safely while reaching best effect in TKI combination therapy.

Read the detailed description

If the subjects qualify to take part in this research study, they will undergo the following procedures.

Subjects will be asked to abstain from alcoholic beverages (24 hours), grapefruit products, herbal supplements/teas, and over-the-counter medications (48 hours) prior to the study visits. There will be two study periods in this study. During each period all the subjects are outpatients and there will be no overnight stay. During each study period, the subjects will come to the University of Florida Clinical Research Center (UF CRC) three times: on Day -1, Day 1, and Day 2, respectively. Subjects will report to the UF CRC the day before Day 1 (i.e. Day -1) to have clinical lab test and urine pregnancy test (female only). Subjects will come to UF CRC at 6:30 a.m. on Day 1 and Day 2 of each study visit. During the morning of each study period (around 8:30 am) subjects will be randomly assigned to receive a single oral dose of dasatinib 20 mg either with or without a single oral dose of imatinib 400 mg administered one hour prior to dasatinib. After the first study visit, the subjects will return one to two weeks later for the second study visit, receiving the opposite treatment. The treatment order for the study visits will be assigned randomly. The end point measures for this study are plasma concentrations of dasatinib. A total of twelve (12) blood samples will be collected for a total amount of 84 ml (about 3 ounces or about 6 tablespoonsful) for each subject during each study period.

Being tested
Dasatinib, Dasatinib+Imatinib

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DasatinibDrug

    Also called Sprycel

    In this group, subjects will take dasatinib only. Dose regimen: dasatinib 20 mg single oral dose

  • Dasatinib+ImatinibDrug

    Also called Other names of Dasatinib: Sprycel, Other names of Imatinib: Gleevec

    In this group, subjects will take imatinib prior to dasatinib administration.

    Dose regimen: Imatinib: 400 mg single oral dose Dasatinib: 20 mg single oral dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Dasatinib and Dasatinib+Imatinib in people with Healthy Volunteers, run by University of Florida.

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 4 inclusion and 8 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: withdrawn, as of the sponsor's last update on 6 Oct 2014. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

The study was withdrawn before enrolling participants, so there are no results.

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?

Area under the plasma concentration versus time curve (AUC) of dasatinib (time frame: 0, 0.5, 1, 1.5, 2, 3, 4, 6, 9, 12, 15, and 24 hours post-dose). 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 6 Oct 2014.
