Condition(s) targeted: Unspecified Adult Solid Tumor, Protocol Specific

Intervention: Ixabepilone (Drug); Sunitinib (Drug)

Phase: Phase 1

Status: Completed

Summary

RATIONALE: Drugs used in chemotherapy, such as ixabepilone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Sunitinib malate 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. PURPOSE: This phase I trial is studying the side effects and best dose of ixabepilone when given together with sunitinib malate in treating patients with progressive advanced solid tumors.

Clinical Details

Official title: A Phase I Trial of Weekly and Every Three Weeks Ixabepilone and Sunitinib in Solid Tumor Patients

Study design: Allocation: Non-Randomized, Endpoint Classification: Safety Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Safety and toxicity profile as assessed by NCI CTCAE version 3.0

Recommended Phase II dose of Ixabepilone when administered with Sunitinib

Secondary outcome:

Pharmacokinetic profiles of Ixabepilone and Sunitinib malate and correlation with activity and/or toxicity

Efficacy data (complete response, partial response, or stable disease) of these treatment combinations

Correlation of changes in angiogenesis biomarkers with clinical (safety and efficacy) and pharmacokinetic parameters

Estimation of optimal biological dose

Detailed description: OBJECTIVES: Primary

- To determine the safety and toxicity profile of ixabepilone in combination with

sunitinib malate in patients with progressive, advanced non-hematologic malignancies.

- To determine the recommended phase II dose of ixabepilone given weekly versus once

every three weeks in combination with a fixed dose of sunitinib malate in these patients. Secondary

- To evaluate the pharmacokinetic profiles of the combination of ixabepilone and

sunitinib malate and correlate them with activity and/or toxicity.

- To obtain preliminary efficacy data (complete response, partial response, or stable

disease) of these treatment combinations.

- To correlate changes in angiogenesis biomarkers with clinical (safety and efficacy) and

pharmacokinetic parameters in patients treated with these drug combinations.

- To estimate the optimal biological dose.

OUTLINE: This is a dose escalation study of ixabepilone. Patients are assigned to 1 of 2 treatment groups.

- Schedule A: Patients receive ixabepilone IV on days 1, 8, and 15. Beginning on day 8 of

course 1, patients also receive oral sunitinib malate once daily. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

- Schedule B: Patients receive ixabepilone IV on day 1. Beginning on day 8 of course 1,

patients also receive oral sunitinib malate once daily. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. Blood samples are collected periodically for biomarker and pharmacokinetic studies by flow cytometry. After completion of study therapy, patients are followed at 30 days and every 3 months for 1 year.
