Purpose:
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing
so they stop growing or die.
PURPOSE: Phase I/II trial to study the effectiveness of CC-1088 in treating patients who
have chronic lymphocytic leukemia that has not responded to previous therapy.
Study summary:
OBJECTIVES: I. Determine the toxicity of CC-1088 in patients with refractory, progressive,
B-cell chronic lymphocytic leukemia. II. Determine the response rate to this treatment in
these patients.
OUTLINE: Patients receive oral CC-1088 three times a day for 28 days. Treatment continues in
the absence of disease progression or unacceptable toxicity.
PROJECTED ACCRUAL: A total of 11-20 patients will be accrued for this study.
Criteria:
DISEASE CHARACTERISTICS: Histologically or cytologically confirmed refractory,
progressive, B-cell chronic lymphocytic leukemia Failed prior first line therapy of
chlorambucil or fludarabine (or their equivalent) Progressive disease as defined by at
least one of the following: Greater than 50% increase in the sum of the products of at
least 2 lymph nodes on two consecutive determinations 2 weeks apart (at least one lymph
node must be greater than 2 cm) Appearance of new palpable lymph nodes At least a 50%
increase in size of previously palpable liver or spleen Appearance of palpable
hepatomegaly or splenomegaly not previously present At least a 50% increase in the
absolute lymphocyte count to at least 5,000/mm3 Transformation to an aggressive histology
(e.g., Richter's or prolymphocytic leukemia) High risk OR Intermediate risk with active
disease, as defined by the following: Greater than 10% weight loss Extreme fatigue Fevers
greater than 100.5 Fahrenheit for greater than 2 weeks without infection Night sweats
