Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
Treatment was from initiation of study drug(s) to 4 weeks after last administration of study drug. Follow-up was for those without disease progression and ended upon disease progression or primary endpoint analysis whichever came first. Observation included those with disease progression who were observed for alternative rx and overall survival.

Reporting Groups

Combination Arm (FluCAM) Participants received both fludarabine (Fludara) and alemtuzumab (Campath) intravenously. Initial escalation of alemtuzumab from 3 to 30 mg (escalation can take up to 14 days). Up to six cycles of fludarabine 30 mg/m^2 intravenous (IV) followed by alemtuzumab 30 mg IV on the first 3 days of each 28 day cycle.

[1] The number of participants whose largest lymph node by physical exam assessment during a baseline visit fell within two categories: <5 cm and >=5 cm. If there is no enlarged lymph node, then size is classified as <5 cm.
[2] Per protocol, all participants had a WHO performance status of 0 or 1. A WHO performance status of 0 is defined as "patient is able to carry out all normal activity without restriction," and status of 1 is "patient is ambulatory and capable of all self-care but unable to carry out any work; up and about more than 50% of waking hours."
[3]

Rai staging is a way to categorize the disease progression of chronic lymphocytic leukemia (CLL); higher stages reflect increasing severity.

Rai Stage 0: Lymphocytosis only, Rai Stage I: Lymphocytosis with lymphadenopathy, Rai Stage II: Lymphocytosis with hepatomegaly or splenomegaly, Rai Stage III: Lymphocytosis with anemia, Rai Stage IV: Lymphocytosis with thrombocytopenia.

Per protocol, the 4 participants with Rai Stage 0 were eligible for the study because they had Binet Stage A.
[4]

Binet staging classifies CLL according to the number of lymphoid tissues involved, as well as the presence of low red blood cell count (anemia) or low number of blood platelets (thrombocytopenia).

Binet Stage A: fewer than three areas of enlarged lymphoid tissue. Enlarged lymph nodes of the neck, underarms, and groin, as well as the spleen, are each considered "one group," whether unilateral (one-sided) or bilateral (on both sides).

Binet Stage B: more than three areas of enlarged lymphoid tissue.

Binet Stage C: anemia plus thrombocytopenia (platelets <100 x 10^3/dL).
[5] Count of participants with refractory or relapsed disease at baseline (as reported by the investigator).
[6] Count of participants who had prior therapy categorized by type of therapy: fludarabine-containing therapy or non-fludarabine-containing therapy.
