Clinical Trial Summary

This phase I trial is studying the side effects and best dose of flavopiridol when given together with vorinostat in treating patients with relapsed or refractory acute leukemia or chronic myelogenous leukemia or refractory anemia. Flavopiridol and vorinostat may cause leukemia cells to look more like normal cells, and to grow and spread more slowly. Vorinostat may also stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving flavopiridol together with vorinostat may be an effective treatment for leukemia or refractory anemia.


Clinical Trial Description

PRIMARY OBJECTIVE:

I. Determine recommended phase II doses for the combination of flavopiridol and vorinostat in patients with acute leukemia, chronic myelogenous leukemia in blast crisis, or refractory anemia with excess blasts-2.

SECONDARY OBJECTIVES:

I. Determine the safety, toxicity, tolerability, and maximum tolerated dose of this drug regimen.

II. Determine the pharmacodynamic and clinical anti-leukemic effects of this drug regimen.

III. Correlate leukemia gene expression patterns with response in patients treated with this regimen.

OUTLINE: This is an open-label, dose-escalation study of flavopiridol.

Patients receive flavopiridol IV over 1 hour on days 1-5 and oral vorinostat three times daily on days 1-14. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Cohorts of 3-6 patients receive escalating doses of flavopiridol 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. ;
