Bortezomib and Topotecan in Treating Patients With Advanced Solid Tumors

Phase I Study of Weekly Bortezomib (VELCADE, PS-341) and Weekly Topotecan (HYCAMTIN) in Solid Tumor Patients With an Emphasis on Small Cell Lung Cancer (SCLC)

RATIONALE: Bortezomib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as topotecan, 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 may kill more tumor cells.

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

Study Overview

• Status: Completed
• Conditions: Lung Cancer; Unspecified Adult Solid Tumor, Protocol Specific
• Intervention / Treatment: Drug: bortezomib; Drug: topotecan hydrochloride; Other: flow cytometry; Other: immunoenzyme technique; Other: immunohistochemistry staining method; Other: laboratory biomarker analysis

Detailed Description

OBJECTIVES:

Primary

• Evaluate the safety and feasibility of bortezomib and topotecan hydrochloride in patients with advanced solid tumors.

Secondary

• Determine the maximum tolerated dose (MTD) of bortezomib and topotecan hydrochloride in these patients.
• Determine, preliminarily, the efficacy of this regimen in these patients.
• Perform laboratory correlative studies on tumor tissue and blood samples from these patients to investigate potential predictors of response.
• Obtain fresh tumor tissue for correlative studies from a subset of patients with small cell lung cancer treated at the MTD.

OUTLINE: This is a dose-escalation study.

Patients receive topotecan hydrochloride IV over 30 minutes followed by bortezomib IV on days 1, 8, and 15. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients with stable or responding disease may continue to receive bortezomib alone in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of topotecan hydrochloride and bortezomib until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose-limiting toxicity.

Ten additional patients with small cell lung cancer are treated at the MTD. These patients undergo tumor biopsy at baseline and before the second course of therapy.

Tumor tissue is collected at baseline in all patients. Blood samples are collected at baseline, at the beginning of courses 2 and 3, and after completion of study treatment. Samples are examined for topoisomerase-1 levels by western blotting; BCL-2, BCL-xL, BAX, and p27 by immunohistochemistry; hypoxia-inducible factor-1, plasminogen-activator inhibitor 1, vascular endothelial growth factor, and osteopontin by immunoenzyme techniques; and NF-kB and p27 nuclear expression by flow cytometry.

After completion of study treatment, patients are followed for 30 days.

PROJECTED ACCRUAL: A total of 34 patients will be accrued for this study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Safety	If cumulative toxicities are seen in subsequent treatment cycles, a decision regarding modification or discontinuation of the study drug and/or patient enrollment will be made by the sponsor in conjunction with the investigator.	Monitored on an ongoing basis during the study

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Toxicity	Toxicity will be evaluated based on the standard NCI CTC grading criteria version 3.0.	On Day 8 and at beginning of subsequent cycles
Response rate	As assessed by RECIST criteria	At baseline and every 2 courses during treatment
Best response	Best response is determined from the sequence of objective status.	From start of treatment until disease progression/recurrence
Survival	Patients will be followed for 30 days after removal from study treatment or until all treatment-related toxicities resolve to < grade 1.	From registration to time of death due to any cause
Progression-free survival	If a patient has not progressed or died, progression-free survival is censored at the time of last follow-up.	From registration to the first observation of disease progression or death due to any cause
