Bortezomib and Topotecan Hydrochloride in Treating Patients With Advanced Solid Tumors

Phase 1
Completed
Conditions
Unspecified Adult Solid Tumor, Protocol Specific
Interventions
Other: immunohistochemistry staining method
Other: pharmacological study
Registration Number
NCT00541359
Lead Sponsor
City of Hope Medical Center
Brief Summary

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Drugs used in chemotherapy, such as topotecan hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving bortezomib together with topotecan hydrochloride may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of topotecan hydrochloride when given together with bortezomib in treating patients with advanced solid tumors.

Detailed Description

PRIMARY OBJECTIVES:

I. To assess the safety and feasibility of combining PS-341 with topotecan in patients with advanced solid tumor malignancies.

II. To define the maximum tolerated dose (MTD) of topotecan when administered in combination with a fixed dose of PS-341 and to described the toxicities at each dose studied.

III. To evaluate the pharmacokinetics of topotecan when given in combination with PS-341 at MTD.

SECONDARY OBJECTIVES:

I. To perform laboratory correlative studies on patients tissue investigating potential predictors of response.

OUTLINE:

PART I (completed as of 09/06/06; all patients enrolled in study after 09/06/06 are enrolled in part II): Patients receive escalating doses of topotecan hydrochloride IV over 30 minutes on days 1 and 8 followed 6 hours later by bortezomib IV on days 1, 4, 8, and 11. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity.

PART II: Patients receive bortezomib IV on days 1, 4, 8, and 11 followed 6 hours later by escalating doses of topotecan hydrochloride IV over 30 minutes on days 1 and 8. Treatment repeats every 21 days for at least 4 courses in the absence of disease progression or unacceptable toxicity.

In both parts of the study, patients who achieve a response may receive additional courses of treatment.

After completion of study treatment, patients are followed periodically.
