E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ibrutinib compared to ofatumumab based on independent review committee (IRC) assessment of progression-free survival (PFS) per International Workshop on Chronic Lymphocytic Leukemia Criteria (IWCLL, Hallek 2008) with incorporation of the clarification for treatment related lymphocytosis (Hallek 2012) (hereafter referred to as IWCLL 2008 criteria) in patients with relapsed or refractory CLL/SLL. |

E.2.2 | Secondary objectives of the trial |
To compare between the two treatment groups in terms of:
Efficacy
• To evaluate IRC-assessed overall response rate (ORR) per IWCLL 2008
criteria

• To evaluate patient-reported outcome (PRO) by FACiT-Fatigue
• To evaluate hematological improvement
Safety
• To evaluate the safety and tolerability of ibrutinib compared to of

12. History of prior malignancy, with the exception of the following:
a) Malignancy treated with curative intent and with no evidence of active disease present for more than 3 years prior to Screening and felt to be at low risk for recurrence by treating physician

evidence of disease or adequately controlled non-melanomatous skin cancer
c) Adequately treated cervical carcinoma in situ without current
evidence of disease
13. Currently active clinically significant cardiovascular disease such as uncontrolled arrhythmia, congestive heart failure, any Class 3 or 4 cardiac disease as defined by the New York Heart Association Functional Classification (Appendix K), or history of myocardial infarction within 6 months prior to first dose with study drug
14. Unable to swallow capsules or disease significantly affecting
gastrointestinal function and/or inhibiting small intestine absorption such as; malabsorption syndrome, resection of the small bowel, or poorly controlled inflammatory bowel disease affecting the small intestine
15. Uncontrolled active systemic fungal, bacterial, viral, or other
infection (defined as exhibiting ongoing signs/symptoms related to the infection and without improvement, despite appropriate antibiotics or other treatment) or ongoing intravenous anti-infective treatment
16. Known history of infection with human immunodeficiency virus (HIV)
17. Serologic status reflecting active hepatitis B or C infection. Patients
with hepatitis B core antibody positive who are surface antigen negative or who are hepatitis C antibody positive will need to have a negative polymerase chain reaction (PCR) result prior to
enrollment. Those who are hepatitis B surface antigen positive or
hepatitis B PCR positive and those who are hepatitis C PCR positive will be excluded.
18. History of stroke or intracranial hemorrhage within 6 months prior to randomization
19. Pregnant or lactating women

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Depends on PFS events as the primary endpoint of this study is PFS, as
assessed by IRC review per IWCLL 2008 criteria. |
|
E.5.2 | Secondary end point(s) |
To compare between the two treatment groups in terms of:
