|Condition or disease||Intervention/treatment||Phase|
|Relapsed or Refractory Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma||Drug: ofatumumab Drug: ibrutinib||Phase 3|
Study PCYC-1112-CA is a randomized, multicenter, open-label, phase 3 study of the Bruton's Tyrosine Kinase (BTK) inhibitor Ibrutinib (PCI-32765) versus Ofatumumab in patients with Relapsed or Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma.
Patients randomized to the ofatumumab arm may be considered to receive next subsequent therapy with ibrutinib.

Active Comparator: Ofatumumab (Arm A)
An anti-CD20 monoclonal antibody
The ofatumumab (IV) dosage and schedule is 12 doses administered over 24 weeks or until disease progression, unacceptable toxicity.
Week 1: 300 mg initial dose Week 2 through 8: 2,000 mg (once weekly) Week 12, 16, 20 and 24: 2,000 mg (every 4 weeks)
Experimental: ibrutinib (Arm B)
A Bruton Tyrosine Kinase Inhibitor
ibrutinib 420 mg (3 x 140-mg capsules) will be administered orally once daily until disease progression or unacceptable toxicity
- PFS (Progression Free Survival) by Independent Review Committee (IRC), Limited to the Time of Primary Analysis 06 November 2013 [ Time Frame: Analysis was conducted after observing approximately 117 PFS events, which occurred about 18 months after the first subject was enrolled. ]The primary objective of this study was to evaluate the efficacy of ibrutinib compared to ofatumumab based on independent review committee (IRC) assessment of progression-free survival (PFS) according to 2008 IWCLL guidelines.
- Overall Response Rate (ORR) by Independent Review Committee (IRC) [ Time Frame: About 18 months after the first subject was enrolled ]Overall Response Rate per the IWCLL 2008 criteria as assessed by IRC, limited to the time of primary analysis 06 November 2013
- OS (Overall Survival) [ Time Frame: OS analysis was conducted at the time of study closure, including up to 6 years of study follow-up ]OS analysis was conducted at the time of study closure, with no adjustment for crossover from the ofatumumab arm to the ibrutinib arm
- Rate of Sustained Hemoglobin and Platelet Improvement [ Time Frame: From study initiation to study closure, including up to 6 years of study follow-up ]Proportion of subjects with hemoglobin (HgB) increase >=20 g/L and platelet (PLT) increase >=50% over baseline continuously for >=56 days without blood transfusions or growth factors.
- Progression Free Survival (PFS) by Investigator With up to 6 Years of Study Follow-up [ Time Frame: From study initiation to study closure, including up to 6 years of study follow-up ]Long-Term Progression Free Survival as assessed by the investigator with up to 6 years of study follow-up
- Overall Response Rate (ORR) by Investigator [ Time Frame: From study initiation to study closure, including up to 6 years of study follow-up ]Overall response per the IWCLL 2008 criteria as assessed by Investigator with up to 6 years of study follow-up
