Brief Summary:
The purpose of the study is to evaluate whether treatment with ibrutinib as a monotherapy results in a clinically significant improvement in progression free survival (PFS) as compared to treatment with ofatumumab in patients with relapsed or refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)

Condition or disease Intervention/treatment Phase
Relapsed or Refractory Chronic Lymphocytic Leukemia Small Lymphocytic Lymphoma Drug: ofatumumab Drug: ibrutinib Phase 3

Detailed Description:

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.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: 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
Actual Study Start Date : June 2012
Actual Primary Completion Date : November 2013
Actual Study Completion Date : October 25, 2018

Arm Intervention/treatment
Active Comparator: Ofatumumab (Arm A)
An anti-CD20 monoclonal antibody
Drug: ofatumumab

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
Drug: ibrutinib
ibrutinib 420 mg (3 x 140-mg capsules) will be administered orally once daily until disease progression or unacceptable toxicity

Primary Outcome Measures :
  1. PFS (Progression Free Survival) [ 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).

    Progressive disease according to 2008 IWCLL guidelines was defined as:

    • Group A

      • Lymphadenopathy, increase ≥50%
      • Hepatomegaly, increase ≥50%
      • Splenomegaly, increase ≥50%
      • Blood lymphocytes, increase ≥ 50% over baseline
    • Group B

      • Platelets counts, decrease of ≥ 50% from baseline secondary to CLL
      • Hemoglobin, decrease of > 2 g/dL from baseline secondary to CLL

Secondary Outcome Measures :
  1. OS (Overall Survival) [ Time Frame: OS analysis was conducted at the time of the interim PFS analysis, which was about 18 months after the first subject was enrolled. ]
  2. Hematological Improvements [ Time Frame: 2 years ]
