|ClinicalTrials.gov Identifier: NCT00662636|
Recruitment Status : Completed
First Posted : April 21, 2008
Last Update Posted : March 23, 2017
RATIONALE: Dasatinib and lapatinib ditoslylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PURPOSE: This phase I trial is studying the side effects and best dose of dasatinib and lapatinib ditoslylate when given together in treating patients with advanced solid tumors that cannot be removed by surgery.
|Condition or disease||Intervention/treatment||Phase|
|Unspecified Adult Solid Tumor, Protocol Specific||Drug: dasatinib Drug: lapatinib ditosylate Other: pharmacological study Other: laboratory biomarker analysis||Phase 1|
I. To determine the maximally tolerated dose of dasatinib combined with lapatinib.
II. To describe the toxicities associated with this treatment combination. III. To assess the pharmacokinetic interaction of lapatinib and dasatinib. IV. To assess the effect of the lapatinib and dasatinib combination on circulating tumor cells and on osteoclast precursor activation.
V. To study the association of clinical (toxicity and/or tumor response or activity) with the pharmacokinetic parameters, and/or biologic (pharmacodynamic) results.
VI. To describe the responses of this treatment combination.
OUTLINE: This is a multicenter, phase I, dose-escalation study. COHORT I: Patients receive oral dasatinib and oral lapatinib ditosylate once daily on days 1-28.
COHORT II: Patients receive oral dasatinib once daily on days 1 and 9-28 and oral lapatinib ditosylate once daily on days 2-28 of course 1. In all subsequent courses patients receive oral dasatinib and oral lapatinib ditosylate once daily on days 1-28.
In both cohorts courses repeat every 28 days, in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for 3 months.
