Title: An Open-labeled, Randomized, Two-dose, Parallel Group Trial of Ofatumumab, a Fully Human Monoclonal Anti-CD20 Antibody, in Combination With Fludarabine and Cyclophosphamide, in Patients With Previously Untreated B-cell CLL
Brief Summary: To investigate the safety and efficacy of two dose regimes of ofatumumab in combination with chemotherapy in previously untreated patients with B-CLL


Options:
A: DISEASE CHARACTERISTICS:

* Diagnosed B-cell chronic lymphocytic leukemia (CLL) defined by the National Cancer Institute (NCI) Working Group criteria
* Meets 1 of the following criteria:

  * Binet stage C disease
  * Binet stage B disease AND ≥ 1 of the following signs or symptoms\*:

    * B symptoms (night sweats, weight loss ≥ 10% within the previous 6 months, fevers \> 38°C or 100.4°F for ≥ 2 weeks without evidence of infection), or constitutional symptoms (fatigue)
    * Continuous progression (doubling of peripheral lymphocyte count within the past 6 months and absolute lymphocyte count \> 50 G/I)
    * Evidence of progressive marrow failure as manifested by the development/worsening of anemia and/or thrombocytopenia
    * Massive, progressive or painful splenomegaly or hypersplenism
    * Massive lymph nodes or lymph node clusters (\> 10 cm in longest diameter), danger of organ complications through large lymphoma (e.g., vascular compression or tracheal narrowing), or progressive lymphadenopathy
    * Occurrence of symptomatic hyperviscosity problems at leukocyte counts \> 200 G/I (symptomatic leukostasis) NOTE: \* Marked hypogammaglobulinemia or the development of a monoclonal protein in the absence of any of the above criteria for active disease is not sufficient for eligibility
* No Binet stage A disease
* No transformation to an aggressive B-cell malignancy (e.g., diffuse large cell lymphoma, Richter's syndrome, or prolymphocytic leukemia)

PATIENT CHARACTERISTICS:

* Eastern Cooperative Oncology Group (ECOG) performance status 0-1
* Cumulative Illness Rating Scale (CIRS) score \> 6
* Life expectancy \> 6 months
* Bilirubin ≤ 2 times upper limit of normal (ULN)
* Alkaline phosphatase and transaminases ≤ 2 times ULN
* Creatinine clearance ≥ 70 mL/min
* Not pregnant or nursing
* Negative pregnancy test
* Fertile patients must use effective contraception during and for 2 months after study treatment
* No known hypersensitivity with anaphylactic reaction to humanized monoclonal antibodies or any of the study drugs
* No cerebral dysfunction that precludes chemotherapy
* No active bacterial, viral, or fungal infection
* No clinically significant autoimmune cytopenia or Coombs-positive hemolytic anemia
* No other active malignancy requiring concurrent treatment except basal cell carcinoma or tumors treated curatively by surgery
* No medical or psychological condition that would preclude study therapy
* No concurrent disease that requires prolonged (\> 1 month) therapy involving glucocorticoids

PRIOR CONCURRENT THERAPY:

* No previous treatment of CLL by chemotherapy, radiotherapy, or immunotherapy
B: Inclusion Criteria:

1. Patients with active B-CLL and with an indication for treatment
2. Age ≥ 18 years
3. Following receipt of verbal and written information about the study, the patient must provide signed informed consent before any study related activity is carried out

Exclusion Criteria:

1. Any previous treatment for B-CLL or any other treatments that can be considered active against B-CLL
2. Glucocorticoid unless given in doses ≤ 10 mg /day for other indications than B-CLL (e.g. asthma)
3. Known transformation of B-CLL
4. Known CNS involvement of B-CLL
5. Past or current malignancy, except for:

   1. Cervical carcinoma Stage 1B or less
   2. Non-invasive basal cell and squamous cell skin carcinoma
   3. Malignant melanoma with a complete response of a duration of \> 10 years
   4. Other cancer diagnoses with a complete response of a duration of \> 5 years
6. Chronic or current infectious disease requiring systemic treatment
7. Clinically significant cardiac disease
8. Significant concurrent, uncontrolled medical condition
9. History of significant cerebrovascular disease
10. Known HIV positive
11. Positive serology for hepatitis B, unless due to vaccination
12. Leukapheresis, except as a safety measure before chemotherapy
13. ECOG Performance Status of 3 or 4
14. Patients who at the time of inclusion are not expected to be able to complete the ofatumumab-FC regimen
15. Patients who have received treatment with any non-marketed drug substance or experimental therapy within 4 weeks prior to Visit 1
16. Current participation in any other interventional clinical study
17. Patients known or suspected of not being able to comply with a study protocol (e.g. due to alcoholism, drug dependency or psychological disorder)
18. Breast feeding women or women with a positive pregnancy test at Visit 1
19. Women of childbearing potential not willing to use adequate contraception for up to one year after last dose of ofatumumab. Adequate contraception is defined as hormonal birth control or intrauterine device. For patients in the USA the use of a double barrier method is also considered adequate.
C: Inclusion Criteria:

* confirmed CLL diagnosis and active CLL requiring treatment
* considered inappropriate for fludarabine-based therapy
* not been treated for CLL before
* fully active at a minimum or fully capable of selfcare and up and about more than 50% of waking hours
* age 18yrs or older
* signed written informed consent

Exclusion Criteria:

* prior CLL therapy
* abnormal/inadequate blood values, liver, and kidney function
* certain heart problems, active or chronic infections, serious significant diseases, active autoimmune hemolytic anemia (AIHA) requiring treatment, other current cancer or within last 5 years
* CLL transformation
* CLL central nervous system involvement
* current participation in other clinical study
* inability to comply with the protocol activities
* lactating or pregnant women or female patients of child-bearing potential (or male patients with such partners) not willing to use adequate contraception
D: Inclusion Criteria:

1. Tumor cell phenotype consistent with B-CLL
2. Patients with active B-CLL and with an indication for treatment
3. Failing at least one fludarabine-containing treatment regimen
4. Failing at least one alemtuzumab-containing treatment regimen
