Erlotinib Hydrochloride and Irinotecan Hydrochloride in Treating Patients With Advanced Solid Tumors
Summary
Phase I trial to study the effectiveness of combining erlotinib hydrochloride with irinotecan hydrochloride in treating patients who have advanced solid tumors. Erlotinib hydrochloride may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining erlotinib hydrochloride and chemotherapy may kill more tumor cells
Description
OBJECTIVES:
I. Determine the maximum tolerated dose (MTD) of erlotinib (erlotinib hydrochloride) and irinotecan (irinotecan hydrochloride), in relation to presence or absence of UGT1A1*28 polymorphism, in patients with advanced solid tumors that overexpress epidermal growth factor receptor.
II. Determine the dose-limiting toxicity of these regimens in these patients. III. Determine whether erlotinib alters the disposition of irinotecan using a previously described limited sampling model.
IV. Determine factors that influence the disposition of these drugs, including genetic variation in UGT1A1 and BCRP, in patients treated with these regimens.
V. Determine factors that influence the disposition of these drugs, in terms of tumor BCRP-expression, in tumor samples from patients treated with these drugs at the MTD.
VI. Evaluate the effect of this regimen on epidermal growth factor receptor phosphorylation in these patients.
VII. Assess, preliminarily, any antitumor activity in patients treated with these regimens.
VIII. Correlate, preliminarily, EGFR phosphorylation and/or BCRP -expression with response in tumor samples from these patients.
OUTLINE: This is a dose-escalation study. Patients are stratified according to UGTA1A genotype (all patients regardless of genotype [closed to accrual as of 9/15/04] vs UGT1A1 6/6 genotype vs UGTA1A 6/7 or 7/7 genotype).
Patients receive oral erlotinib hydrochloride daily on days -6 to -1. Patients then receive irinotecan hydrochloride intravenously (IV) over 90 minutes on day 1 and oral erlotinib once daily on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Cohorts of 3-6 patients per stratum receive escalating doses of erlotinib hydrochloride and irinotecan hydrochloride until the MTD is determined. The MTD is defined as the dose preceding that at which at least 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Additional patients are treated at the MTD.
Patients are followed for 3 months.

Tetramethylphenylenediamine
Used in the form of the hydrochloride as a reagent in ANALYTICAL CHEMISTRY TECHNIQUES.
Naphthylvinylpyridine
4(1-Naphthylvinyl)pyridine hydrochloride. Cholinesterase inhibitor. Synonym: YuB 25.
Ambroxol
A metabolite of BROMHEXINE that stimulates mucociliary action and clears the air passages in the respiratory tract. It is usually administered as the hydrochloride.
Bupropion
A unicyclic, aminoketone antidepressant. The mechanism of its therapeutic actions is not well understood, but it does appear to block dopamine uptake. The hydrochloride is available as an aid to smoking cessation treatment.
Mechlorethamine
A vesicant and necrotizing irritant destructive to mucous membranes. It was formerly used as a war gas. The hydrochloride is used as an antineoplastic in Hodgkin's disease and lymphomas. It causes severe gastrointestinal and bone marrow damage.
