| E.2.3 | Trial contains a sub-study  |  No  | 
| E.3 | Principal inclusion criteria  | 
1. Adults with documented diagnosis of CLL based on the modified IWCLL updated NCI-WG guidelines
 [Hallek, 2008]
 2. At least PR according to the revised 2008 NCI-WG CLL criteria, within 3 months of the response assessment
 after the last dose of 2nd/3rd line treatment
 3. The anti-leukemic treatment before study entry should have been at least 3 months or 3 cycles of
 polychemotherapy (e.g. CVP), fludarabine-containing chemotherapy or immunochemotherapy
 4. ECOG Performance Status of 0-2
 5. Signed written informed consent prior to performing any study-specific procedures
 French subjects: In France, a subject will be eligible for inclusion in this study only if either affiliated to or a
 beneficiary of a social security category.
 E.  | 
 
 
 | 
| E.4 | Principal exclusion criteria | 
1. Known primary or secondary fludarabine-refractory subjects, defined as treatment failure (failure to achieve a
 CR or PR) or disease progression within 6 months [Hallek, 2008]
 2. Prior maintenance therapy
 3. Known transformation of CLL (e.g. Richter’s transformation), prolymphocytic leukemia (PLL), or CNS
 involvement of CLL
 4. Active Autoimmune Hemolytic Anemia (AIHA) requiring treatment except if in the opinion of the investigator
 it is thought not to affect the subject’s safety, the conduct of the study or the interpretation of the data
 5. Previous autologous or allogeneic stem cell transplantation
 6. Chronic or current active infectious disease requiring systemic antibiotics, antifungal, or antiviral treatment
 such as, but not limited to, chronic renal infection, chronic chest infection with bronchiectasis, tuberculosis and
 active Hepatitis B or C
 (Positive serology for Hepatitis B (HB) defined as a positive test for HBsAg. In addition, if negative for HBsAg
 but HBcAb positive (regardless of HBsAb status), a HBV DNA test will be performed and if positive the subject
 will be excluded*.)
 7. Other past or current malignancy (with the exception of basal cell carcinoma of the skin or in situ carcinoma
 of the cervix or breast) unless the tumor was successfully treated with curative intent at least 2 years prior to trial
 entry except if in the opinion of the investigator it is thought not to affect the subject’s safety, the conduct of the
 study or the interpretation of the data
 8. Clinically significant cardiac disease including unstable angina, acute myocardial infarction within 6 months
 prior to screening, congestive heart failure, and arrhythmia requiring therapy, with the exception of extra systoles
 or minor conduction abnormalities except if in the opinion of the investigator it is thought not to affect the
 subject’s safety, the conduct of the study or the interpretation of the data
 9. History of significant cerebrovascular disease or event with symptoms or sequelae
 10. Significant concurrent, uncontrolled medical condition that in the opinion of the investigator contraindicates
 participation in this study
 11. Other anti-leukemic use of medications including glucocorticoids
 12. Known HIV positive
 13. Screening laboratory values:
 • Platelets<50 x 10^9/L
 • Neutrophils<1.0 x 10^9/L
 • Creatinine > 1.5 times upper normal limit (unless normal creatinine clearance)
 • Total bilirubin > 1.5 times upper normal limit (unless due to liver involvement of CLL)
 • Alanine Aminotransferase (ALT) > 2.5 times upper normal limit (unless due to liver involvement of CLL or
 Gilbert's syndrome)
 • Alkaline phosphatase > 2.5 times upper normal limit
 14. Known or suspected hypersensitivity to ofatumumab that in the opinion of the investigator or medical monitor
 contraindicates study participation
 15. Subjects who have received treatment with any non-marketed drug substance or experimental therapy
 within 5-terminal half-lives or 4 weeks whichever is longer prior to first dose of study medication or currently
 participating in any other interventional clinical study
 Note: Participation in any other interventional clinical study after disease progression during post PD follow-up
 is permitted.
 16. Lactating women, women with a positive pregnancy test at Visit 1 or women (of childbearing potential) as
 well as men with partners of childbearing potential, who are not willing to use adequate contraception from
 study start through one year following last ofatumumab dose. Adequate contraception is defined as abstinence,
 oral hormonal birth control, implants of levonorgestrel, estrogenic vaginal ring, percutaneous contraceptive
 patches, intrauterine device, and male partner sterilization if male partner is sole partner for that subject. For
 females in the USA, the use of a double barrier method is also considered adequate (condom or occlusive cap
 plus spermicidal agent).
 * If HBV DNA is negative, subject may be included but must undergo HBV DNA monitoring (see Section 6.3.4).
 Prophylactic antiviral therapy may be initiated at the discretion of the investigator. |

| E.5 End points | 
| E.5.1 | Primary end point(s) | 
The primary endpoint is progression-free-survival (PFS) which is defined as the time from randomization to the
 date of disease progression or death due to any cause. The investigator assessment of response will be assessed
 according to the IWCLL updated NCI-WG CLL criteria [Hallek, 2008].
