Patient must have recovered from the acute side effects incurred as a result of previous therapy. - More than 3 weeks since using investigational agents. Patient must have recovered from the acute side effects incurred as a result of previous therapy. - Serum creatinine and conjugated (direct) bilirubin less than or equal to 2 times the institutional upper limit of normal (ULN) unless secondary to direct infiltration of the liver with CLL. - Female patients with childbearing potential must have a negative pregnancy test (serum or urine) within 2 weeks of first dose of study drug(s). All patients must agree to use an effective contraceptive method while on study treatment, if appropriate, and for a minimum of 6 months following study therapy. - Signed, written informed consent (in the US, includes The Health Insurance Portability and Accountability Act of 1996 (HIPAA) authorization) Exclusion Criteria: - Positive Coombs test and evidence of active hemolysis. - Platelet count less than 50*10^9/L without splenomegaly. - History of anaphylaxis following exposure to rat or mouse derived CDR-grafted humanized monoclonal antibodies. - Previously treated with CAMPATH. - Previous bone marrow transplant. - Known central nervous system (CNS) involvement with B-CLL - Active infection, including human immunodeficiency virus (HIV) positive. - Active second malignancy. - Recent documented history (within 2 years) of active tuberculosis (TB), current active TB infection, currently receiving anti-tuberculous medication (e.g., INH, rifampin, streptomycin, pyrazinamide, or others). - Active hepatitis or a history of prior viral hepatitis B or hepatitis C, or positive hepatitis B serologies. Patients with a positive hepatitis B surface antibody (HBsAb) test with a documented history of prior hepatitis B immunization are eligible as long as other criteria are met (i.e. negative tests for: hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb) and hepatitis C virus antibody (HCVAb)). - Other severe, concurrent diseases (e.g., cardiac or pulmonary disease), mental disorders, or major organ malfunction (liver, kidney) that could interfere with the patient ability to participate in the study. - Pregnant or nursing women. - Cytomegalovirus (CMV) positive by polymerase chain reaction (PCR) (above the level of detection). A patient that is PCR positive will require treatment to reduce the viral load to a non-detectable level; but such a patient may be considered for study entry once the infection has been treated. - Medical condition requiring chronic use of oral corticosteroids at a dose higher than physiologic replacement. |

| Primary | Number of Participants With Best Disease Response as Determined by the Independent Response Review Panel (IRRP) | Participants were evaluated by the IRRP according to National Cancer Institute (NCI) 1996 response criteria. The best response observed during the study is summarized. Response categories include Complete Response (CR) with normal physical exam, marrow cells and blood values, Partial Response (PR) with a >= 50% decrease from baseline in lymphocytes, lymphadenopathy and liver or spleen exam, Stable Disease (SD) without significant progression from baseline, or Progressive Disease (PD) with increased size/number of nodes, size of liver or spleen, increase in lymphocytes, aggressive histology. | up to 44 weeks | No |
| Primary | Percentage of Participants Who Had an Overall Response (OR) as Determined by the Independent Response Review Panel (IRRP) | Participants were evaluated by the IRRP according to National Cancer Institute (NCI) 1996 response criteria. The percentage of participants whose best response observed during the study was either a Complete Response (CR) or a Partial Response (PR). Overall Response (OR) = CR + PR. A Complete Response (CR) exhibits a normal physical exam, marrow cells and blood values. A Partial Response (PR) has a >= 50% decrease from baseline in lymphocytes, lymphadenopathy and liver or spleen exam. | up to 44 weeks | No |
| Secondary | Kaplan-Meier Estimates of Progression Free Survival as Determined by the Independent Response Review Panel (IRRP) | Progression-free survival was defined as the number of days from the date of first treatment to the date of first objective documentation of progressive disease (PD) as determined by the IRRP, or death due to any cause. Results are expressed in months. Progressive Disease (PD) was defined as an increase in size/number of nodes, size of liver or spleen, increase in lymphocytes, or aggressive histology. |
up to 5 years | No |
| Secondary | Kaplan-Meier Estimates of Duration of Response as Determined by the Independent Response Review Panel (IRRP) | Duration of response was analyzed for participants who achieved a complete response (CR) or partial response (PR) and was defined as the number of days from the first date of documented response to the date of progressive disease (PD) as determined by IRRP or death due to any cause. Results are stated in months. Progressive Disease (PD) was defined as an increase in size/number of nodes, size of liver or spleen, increase in lymphocytes, or aggressive histology. |
up to 5 years | No |
| Secondary | Kaplan-Meier Estimates of Overall Survival | Overall survival was defined as the time in days from the date of first treatment to the date of death due to any cause for all participants. Results are stated in months. | up to 5 years | No |
| Secondary | Participants With a Minimal Residual Disease (MRD) Status of Negative | MRD negativity represents a very positive response outcome. MRD negativity in this report was defined by the absence of tumor cells in bone marrow, using 4-color flow cytometry. All patients are evaluated for treatment response based on National Cancer Institute Working Group (NCIWG) criteria. Of patients who have achieved a clinical complete response (CR) or partial response (PR) that met National Cancer Institute Working Group (NCIWG) criteria of CR except blood recovery, a bone marrow sample was taken for flow cytometry measure of MRD negativity. | 44 weeks | No |
| Secondary | Participants With Treatment-Emergent Adverse Events (TEAE) | Number of participants with treatment-emergent adverse events (TEAEs). AEs were graded by the investigator using the Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 and were assessed for relatedness to study treatment (5 point scale from 'not related' to 'definitely related') and severity (5 point scale with grade 5 being most severe). Categories reported include participant counts for treatment-emergent AEs, injection site reactions, AEs for infections, serious AEs, AEs causing discontinuation of study drug(s), deaths and severity. | up to 18 weeks of treatment plus 45 days | Yes |
