Flavopiridol in Treating Patients With Chronic Lymphocytic Leukemia

Phase 2

Completed

• Conditions: B-cell Chronic Lymphocytic Leukemia; Refractory Chronic Lymphocytic Leukemia; Stage I Chronic Lymphocytic Leukemia; Stage II Chronic Lymphocytic Leukemia; Stage III Chronic Lymphocytic Leukemia; Stage IV Chronic Lymphocytic Leukemia
• Interventions: Drug: alvocidib; Other: laboratory biomarker analysis

• Registration Number: NCT00003620
• Lead Sponsor: National Cancer Institute (NCI)

Brief Summary

Phase II trial to study the effectiveness of flavopiridol in treating patients who have chronic lymphocytic leukemia that has not responded to treatment with fludarabine. Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die

Detailed Description

OBJECTIVES: Determine the complete and partial response rate to flavopiridol in patients with fludarabine-refractory chronic lymphocytic leukemia.

Assess the toxicity profile of this treatment in these patients. Examine progression-free survival and overall survival following this treatment in these patients.

Determine the effects of flavopiridol on normal T-cell subsets and immunoglobulin levels in these patients.

OUTLINE: This is an open label, multicenter study.

Patients registered before 9/15/2000 receive flavopiridol IV continuously on days 1-3. Treatment repeats every 14 days for a total of 12 courses in the absence of disease progression or unacceptable toxicity.

Patients registered after 9/15/2000 receive flavopiridol IV over 1 hour daily on days 1-3. Treatment repeats every 3 weeks for a total of 8 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed every 3 months for the first year and then every 6 months for 5 years.

Primary Outcome Measures

Name	Time	Method
Complete + partial response rate	Up to 5 years	The CR + PR rate will be estimated with a 95% confidence interval, and the success of the study will be judged with the two-stage design given above.

Secondary Outcome Measures

Name	Time	Method
Toxicity profile of flavopiridol	Up to 5 years	Toxicities will be tabulated by type and grade
Progression-free survival	From onstudy date to the date of progression or death, assessed up to 5 years	Will be estimated using the Kaplan-Meier method.
Overall survival	From onstudy date to the date of death, assessed up to 5 years
