About this study
Official title: Phase I Pharmacokinetic Study of Dasatinib (BMS-354825) (NSC-732517) in Patients With Advanced Malignancies and Varying Levels of Liver Dysfunction
This phase I trial studies the side effects and best dose of dasatinib in treating patients with solid tumors or lymphomas that are metastatic or cannot be removed by surgery. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Read the detailed description
PRIMARY OBJECTIVES:
- To estimate the maximum tolerated dose (MTD) of dasatinib in patients with varying degrees of hepatic impairment.
II. To estimate the pharmacokinetic (PK) profile of this drug in patients with varying degrees of hepatic impairment.
III. To assess the safety profile and dose-limiting toxicities (if any) of dasatinib in patients with varying degrees of hepatic impairment.
SECONDARY OBJECTIVES:
- To describe any antitumor efficacy associated with dasatinib administration in patients with varying degrees of hepatic impairment.
II. To examine whether the pharmacokinetic clearance of dasatinib correlates with hepatic function as assessed by Child-Pugh Criteria, the National Cancer Institute (NCI) Organ Dysfunction Working Group Criteria, or other assessments of liver function.
OUTLINE: This is a dose-escalation study.
Patients receive dasatinib orally (PO) once daily (QD) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 28 days.

| Treatment (dasatinib) | Experimental | Patients receive dasatinib PO QD on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Receives: Drug: Dasatinib; Other: Pharmacological Study |
What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum tolerated dose of dasatinib, defined as the highest dose level at which less than 33% of 6-9 evaluable patients experience dose-limiting toxicity
Toxicity will be graded according to the NCI CTCAE v3.0.
Measured: 28 days
Pharmacokinetic parameters of dasatinib
Area under curve (AUC)(to infinity), AUC(to 24 hours), and maximum concentration (Cmax) analyzed in the natural log scale. For each PK parameter, the mean difference between the recommended dose for a liver impairment group and the normal liver function group dosed at 140 mg OD (equivalent to ratios of geometric means in the non-log scale) will be tested against 0 at a one-sided 0.05 significance level to detect an increase in the liver impairment group (equivalent to a 2-sided 90% confidence interval).
Measured: Days 1 and 8 of course 1

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Dasatinib and Pharmacological Study in people with Adult Acute Lymphoblastic Leukemia in Remission and Adult B Acute Lymphoblastic Leukemia, run by National Cancer Institute (NCI) at 23 sites in United States.
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 36 inclusion and 0 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 2 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 23 sites in United States. 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?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Maximum tolerated dose of dasatinib, defined as the highest dose level at which less than 33% of 6-9 evaluable patients experience dose-limiting toxicity (time frame: 28 days). The study lists 2 primary outcomes in all. 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 2 Jul 2015.
