Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A Randomized, Multicenter, Open-label, Phase 3 Study of the Bruton's Tyrosine Kinase Inhibitor PCI-32765 versus Chlorambucil in Patients 65 Years or Older with Treatment-naive Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study design: This is a randomized, multicenter, open-label, Phase 3 study designed to compare the safety and efficacy of Ibrutinib versus Chlorambucil in treatment-naive patients 65 years or older who have CLL or SLL.

Eligible patients will be randomized in a 1:1 ratio to Treatment Arm A or B:

* Treatment Arm A: Oral Chlorambucil 0.5 mg/kg on Days 1 and 15 of each 28-day cycle; the dose can be increased, if well tolerated, in increments of 0.1 mg/kg on Day 1 of each cycle to a maximum of 0.8 mg/kg; patients receive a minimum of 3 and a maximum of 12 cycles, in the absence of progressive disease or unacceptable toxicity.
* Treatment Arm B: Oral Ibrutinib 420 mg/day Randomization will be stratified on Eastern Cooperative Oncology Group (ECOG) performance status (0,1 versus 2); presence of advanced Rai stage (yes/no), advanced being defined as Stages 3-4; and geographic region: US versus non-US.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ibrutinib

Ibrutinib will be supplied as hard gelatin 140-mg capsules for oral (PO) administration. Ibrutinib 420 mg (3 x 140-mg capsules) is administered orally once daily. The first dose will be delivered in the clinic on Day 1, after which subsequent dosing is typically on an outpatient basis. Ibrutinib will be dispensed to patients in bottles at each visit.

Group Type EXPERIMENTAL

Ibrutinib

Intervention Type DRUG

Ibrutinib will be supplied as hard gelatin 140-mg capsules for oral (PO) administration. Ibrutinib 420 mg (3 x 140-mg capsules) is administered orally once daily. The first dose will be delivered in the clinic on Day 1, after which subsequent dosing is typically on an outpatient basis. Ibrutinib will be dispensed to patients in bottles at each visit.

Chlorambucil

Chlorambucil will be supplied as 2-mg tablets for PO administration. Chlorambucil is administered orally on Days 1 and 15 of each 28-day cycle.The starting dosage (Cycle 1) is 0.5 mg/kg. If well tolerated, the Chlorambucil dose can be increased starting at Cycle 2, with increments of 0.1 mg/kg on Day 1 of each cycle to a maximum of 0.8 mg/kg.

Group Type ACTIVE_COMPARATOR

Chlorambucil

Intervention Type DRUG

Chlorambucil will be supplied as 2-mg tablets for PO administration. Chlorambucil is administered orally on Days 1 and 15 of each 28-day cycle. The starting dosage (Cycle 1) is 0.5 mg/kg. If well tolerated, the Chlorambucil dose can be increased starting at Cycle 2, with increments of 0.1 mg/kg on Day 1 of each cycle to a maximum of 0.8 mg/kg.
