Thalidomide in Treating Patients With Relapsed Chronic Lymphocytic Leukemia
A Phase II Trial of Thalidomide in Patients With Relapsed Chronic Lymphocytic Leukemia
調査の概要
詳細な説明
PRIMARY OBJECTIVES:
I. To determine whether thalidomide can induce objective responses in relapsed B-CLL patients.
II. To determine the toxicity of thalidomide in this patient population. III. To document if alterations in vascular growth factors and/or bone marrow angiogenesis patterns correlate with thalidomide related clinical responses.
OUTLINE:
Patients receive oral thalidomide daily for 4 weeks. Courses repeat every 4 weeks for up to 1 year in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 5 years.

説明
Inclusion Criteria:
- Diagnosis of chronic lymphocytic leukemia (CLL) evidenced by monoclonal population of mature CD5+, CD19+, CD23+, and B cells
- Relapsed after prior treatment for CLL
Active disease with 1 or more of the following characteristics:
- At least 10% weight loss within the past 6 months
- Fever greater than 100.5 degrees F for at least 2 weeks without evidence of infection
- Night sweats without evidence of infection
- Evidence of progressive marrow failure with anemia (hemoglobin less than 11 g/dL) and/or thrombocytopenia (platelet count less than 100,000/mm^3) (i.e., any stage III or IV disease)
- Autoimmune anemia and/or thrombocytopenia poorly responsive to corticosteroid therapy
- Massive or progressive splenomegaly (i.e., greater than 6 cm below the left costal margin or more than 50% increase over 2 months)
- Progressive lymphadenopathy (i.e., more than 50% increase over 2 months)
- Progressive lymphocytosis (not due to corticosteroids) with an increase of more than 50% over a 2-month period or an anticipated doubling time of less than 6 months
- Marked hypogammaglobulinemia or the development of a monoclonal protein in the absence of any of the above criteria for active disease are not considered evidence of active disease
Measurable disease
- Absolute lymphocyte count greater than 5,000/mm^3
- No bulky lymph node disease greater than 10 cm in at least 1 dimension except splenomegaly
- Performance status - ECOG 0-2
- Absolute neutrophil count at least 500/mm^3
- Platelet count at least 20,000/mm^3 (in absence of sargramostim [GM-CSF])
- Hemoglobin at least 8 g/dL
- Bilirubin no greater than 2.5 times upper limit of normal (ULN)
- AST no greater than 2.5 times ULN
- Creatinine no greater than 1.5 mg/dL
- Creatinine clearance at least 60 mL/min
- No other active malignancy
- No peripheral neuropathy (sensory) grade 2 or greater
- No active infection
- Not pregnant or nursing
- Negative pregnancy test
- Fertile patients must use 1 highly effective method of contraception AND 1 additional effective method of contraception for at least 4 weeks before, during, and for 4 weeks after study completion
- No prior allogeneic bone marrow transplantation
- At least 10 days since prior filgrastim (G-CSF) or GM-CSF
- No more than 3 prior chemotherapy regimens
- At least 30 days since prior chemotherapy
- No concurrent corticosteroids except for adrenal insufficiency
