Lenalidomide in Patients With Chronic Lymphocytic Leukemia Older Than 65 Years of Age

• Status: Completed
• Trial end date: 2016-02-23
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to:

Determine the likelihood that lenalidomide will adequately control the disease for at least one year.

Lenalidomide is a drug that alters the immune system and it may also interfere with the development of tiny blood vessels that help support tumor growth. Therefore, in theory, it may reduce or prevent the growth of cancer cells. Lenalidomide is approved by the Food and Drug Administration (FDA) for the treatment of specific types of myelodysplastic syndrome (MDS) and in combination with dexamethasone for patients with multiple myeloma (MM) who have received at least 1 prior therapy. MDS and MM are cancers of the blood. It is currently being tested in a variety of cancer conditions.

In this case it is considered experimental. The lenalidomide being administered in this study is not a commercially marketed product. Although it is expected to be very similar in safety and activity to the commercially marketed drug, it is possible that some differences may exist. Because this is not a commercially marketed drug, lenalidomide can only be administered to patients enrolled in this clinical trial and may only be administered under the direction of physicians who are investigators in this clinical trial.

Criteria

Inclusion Criteria:

• Patients with either previously untreated or treated disease must have either intermediate or high-risk chronic lymphocytic leukemia as defined by the three-stage Rai system. Patients with Rai intermediate risk disease should meet the criteria for active disease as outlined by the NCI Working Group guidelines (including weight loss, fatigue, fevers, evidence of progressive marrow failure, splenomegaly, progressive lymphadenopathy, or progressive lymphocytosis with a rapid doubling time)(49).

• MSKCC pathologist must confirm patient's disease.

• To be considered CLL the patient must have an absolute lymphocytosis in the blood of at least 5,000 lymphocytes per microliter, or bone marrow lymphocytosis greater than or equal to 30% of all nucleated cells

• Immunophenotypic (or immunohistochemical) analysis of the malignant lymphocytes should demonstrate that the cells are B-cells. Typically these cells should also express CD5 and CD23. It is recognized that an occasional patient with CLL may have a slightly aberrant immunophenotype. All such cases need to be reviewed with the principal investigator prior to being registered for the study. Patients with small lymphocytic lymphoma (CLL type) will be eligible for this study.

• Age ≥ 65 years of age.

• Karnofsky performance status ≥ 50%

• ANC ≥ 0.8 and platelet count ≥ 30,000

• Total creatinine ≤ 2.0mg/dl or creatinine clearance ≥ 30ml/min.

• Total bilirubin ≤ 3.0 mg/dL (not attributable to autoimmune hemolytic anemia).

• Signed informed consent, which indicates the investigational nature of this study, is required.

• No patient may be entered onto the study without consultation with the principal investigator or his designee.

• Men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy. All patients must be counseled at a minimum of every 28 days about pregnancy precautions and risks of fetal exposure.

Exclusion Criteria:

• Patients with significant active infections.

• Men should use effective contraception.

• Patients known positive for HIV or with active infection from hepatitis, A, B, or C.

• Concomitant chemotherapy or radiotherapy while on protocol.

• Evidence of laboratory TLS by Cairo-Bishop Definition of Tumor Lysis Syndrome.

• History of thromboembolic disease within the past 6 months, regardless of anti-coagulation.

• Myocardial infarction within 6 months prior to enrollment, or New York Hospital Association (NYHA) Class III or IV heart failure , uncontrolled angina, severe uncontrolled ventricular arrhythmias, electrocardiographic evidence of acute ischemia or active conduction system abnormalities.

• Known hypersensitivity to thalidomide.

• The development of erythema nodosum if characterized by a desquamating rash while taking thalidomide or similar drugs.

• Any prior use of lenalidomide.
