Summary of "Low dose alemtuzumab in fludarabine-refractory chronic lymphocytic leukemia patients."

Abstract Alemtuzumab has been shown to be effective in poor-prognosis chronic lymphocytic leukemia (CLL); treatment, however, has been associated with relevant toxicity. With the aim of seeking better tolerability, we treated thirty-nine fludarabine-refractory CLL patients with subcutaneous alemtuzumab 10 mg three times a week, for 18 weeks. In 18 randomly selected patients, after obtaining lymphocyte count reduction by 1 Log, the antibody was administered once weekly at the dose of 30 mg. Overall response rate was 44% including a 8% of complete remission. Median overall survival and progression free survival were 29.1 and 10.3 months, respectively. Treatment was well tolerated, severe non-CMV infection occurred in 7% of the patients. CMV reactivation was detected in 27% of the patients, with only one case of CMV disease. No death occurred during therapy. In conclusion, low-dose alemtuzumab shows a promising safety profile coupled with satisfactory effectiveness in this category of poor prognosis CLL patients.

Medical and Biotech [MESH] Definitions

A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma. These terms represent spectrums of the same disease.

A chronic leukemia characterized by a large number of circulating prolymphocytes. It can arise spontaneously or as a consequence of transformation of CHRONIC LYMPHOCYTIC LEUKEMIA.

The phase of chronic myeloid leukemia following the chronic phase (LEUKEMIA, MYELOID, CHRONIC-PHASE), where there are increased systemic symptoms, worsening cytopenias, and refractory LEUKOCYTOSIS.

A lymphoid leukemia characterized by a profound LYMPHOCYTOSIS with or without LYMPHADENOPATHY, hepatosplenomegaly, frequently rapid progression, and short survival. It was formerly called T-cell chronic lymphocytic leukemia.

A pathologic change in leukemia in which leukemic cells permeate various organs at any stage of the disease. All types of leukemia show various degrees of infiltration, depending upon the type of leukemia. The degree of infiltration may vary from site to site. The liver and spleen are common sites of infiltration, the greatest appearing in myelocytic leukemia, but infiltration is seen also in the granulocytic and lymphocytic types. The kidney is also a common site and of the gastrointestinal system, the stomach and ileum are commonly involved. In lymphocytic leukemia the skin is often infiltrated. The central nervous system too is a common site.
