Lenalidomide and AT-101 in Treating Patients With Relapsed B-Cell Chronic Lymphocytic Leukemia
A Phase I/II Clinical Trial of Lenalidomide in Combination With AT-101 for the Treatment of Relapsed B-Cell Chronic Lymphocytic Leukemia (B-CLL)
研究概览
详细说明
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) of lenalidomide in combination with AT-101 (R-(-)-gossypol acetic acid). (Phase I) II. To assess the overall response rate of lenalidomide in combination with AT-101. (Phase II)
SECONDARY OBJECTIVES:
I. To assess the overall response rates of lenalidomide in combination with AT-101 at 6 months and 12 months.
II. To evaluate time to progression (TTP) for the combination of lenalidomide + AT-101.
III. To evaluate the safety of this combination in patients with relapsed B-CLL.
TERTIARY OBJECTIVES:
I. To conduct correlative studies for further understanding of the mechanism of antitumor activity of lenalidomide and lenalidomide + AT-101.
OUTLINE: This is a phase I dose-escalation study of lenalidomide followed by a phase II study.
Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21. Beginning in course 3, patients also receive AT-101 PO twice daily (BID) on days 1-3. Treatment repeats every 28 days for up to 11 courses (49-56 days for course 12 or last course of treatment) in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days and then every 3 months for up to 2 years.

Exclusion Criteria:
- Any serious medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from signing the informed consent form
- Pregnant or lactating females

The proportion of successes will be estimated by the number of successes divided by the total number of evaluable patients.
Confidence intervals for the true success proportion will be calculated according to the approach of Duffy and Santner.
