The target dose of 30 mg over 2 hours, three times weekly, was administered for up to 16 weeks. Responses were evaluated by an independent panel of experts using 1996 National Cancer Institute\u2013sponsored Working Group criteria. Safety assessments included analysis of lymphocyte subpopulations. Antimicrobial prophylaxis was not mandatory. <\/jats:p><jats:p> RESULTS: Eight patients (33%) achieved a major response (all partial remissions), with a median time to response of 3.9 months (range, 1.6 to 5.3 months). The median duration of response was 15.4 months (range, 4.6 to \u2265 38.0 months), the median time to disease progression was 19.6 months (range, 7.7 to \u2265 42.0 months), and the median survival time was 35.8 months (range, 8.8 to \u2265 47.1 months). Acute infusion-related events, mainly grades 1 and 2, were most common and most severe in the first week. Ten patients (eight nonresponders and two responders) experienced major infections on-study. Pneumocystis carinii pneumonia was reported in two patients on-study; neither had received prophylaxis. Median CD4<jats:sup>+<\/jats:sup> and CD8<jats:sup>+<\/jats:sup> counts decreased and then began to increase by the end of the study, with further recovery by 1-month follow-up. One of 53 samples obtained from 10 patients had a low titer of alemtuzumab antibodies. <\/jats:p><jats:p> CONCLUSION: Alemtuzumab has significant activity in poor-prognosis, fludarabine-treated CLL patients. However, because of a relatively high incidence of opportunistic infections accompanying profound lymphopenia, future protocols should include mandatory prophylaxis. <\/jats:p>","DOI":"10.1200\/jco.2002.06.119","type":"journal-article","created":{"date-parts":[[2002,9,12]],"date-time":"2002-09-12T17:42:13Z","timestamp":1031852533000},"page":"3891-3897","source":"Crossref","is-referenced-by-count":239,"title":["Alemtuzumab in Previously Treated Chronic Lymphocytic Leukemia Patients Who Also Had Received Fludarabine"],"prefix":"10.1200","volume":"20","author":[{"given":"K.
