CAN-NCIC-CL1, E-C9011, SWOG-9108, CALGB-9011, CL1
I. Compare progression-free survival of previously untreated patients with intermediate- and high-risk (Rai Stages I-IV) B-cell chronic lymphocytic leukemia (CLL) randomly assigned to treatment with chlorambucil vs. fludarabine, with crossover for patients who fail initial therapy. II. Compare the quality of life (measured by the need for transfusion, incidence of infection, and performance status) of patients on these 2 regimens. III. Determine, by use of a crossover design, whether fludarabine and chlorambucil are cross-resistant. IV. Compare overall survival on these 2 regimens based on "intent to treat" for the crossover.
Previously untreated B-cell chronic lymphocytic leukemia (CLL) defined by presence of all of the following criteria: Lymphocytosis at least 5,000 for at least 4 weeks or lymphocytosis greater than 100,000 at diagnosis Morphologically mature-appearing lymphocytes Normocellular or hypercellular bone marrow with more than 30% of lymphoid nucleated cells Blood lymphocyte immunophenotype mostly B-cell by appropriate marker studies, e.g.: sIg+, CD19+, CD20+, CD24+ with CD5+ OR Kappa or lambda light chain and low cell surface density expression of sIg Intermediate- or high-risk disease (Rai Stages I-IV) required Intermediate-risk disease must be active, evident by at least one of the following criteria: At least one of the following disease-related symptoms: More than 10% weight loss during the preceding 6 months Extreme fatigue Temperature more than 100 F for more than 2 weeks with no evidence of infection Night sweats Massive or progressive splenomegaly and/or lymphadenopathy Progressive lymphocytosis with an increase of more than 50% over preceding 2 months or an anticipated doubling time of less than 12 months No lymphoproliferative disorder other than B-cell CLL allowed Negative direct Coombs' test required No uncontrolled bacterial, viral, or fungal infections No clinical autoimmune disease (e.g., AIHA, ITP) SWOG patients must submit bone marrow aspirates and peripheral blood for immunophenotyping and molecular/cytogenetic studies ECOG patients must be concurrently enrolled on protocol EST-6491 for flow cytometric and bcl-2 expression studies
No prior cytotoxic therapy Prior steroids for immune problems (e.g., AIHA, ITP) allowed No concurrent corticosteroids
Age: At least 18 Performance status: CALGB 0-2 Hematopoietic: See Disease Characteristics Hepatic: Bilirubin no more than 2.0 mg/dl SGOT/SGPT no more than 1.5 x normal Renal: Creatinine no more than 1.5 x normal BUN no more than 1.5 x normal Other: No second malignancy within 5 years except: Inactive nonmelanomatous skin cancer In situ carcinoma of the cervix No serious medical illness that would limit survival to less than 2 years No psychiatric conditions that would preclude informed consent No pregnant women Effective contraception required of fertile women
538 patients will be entered; as of June 3, 1994, accrual is expected to be complete in about 8 months.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
