Scientific title
IciCLLe: Assessment of the Mechanism of Action of Ibrutinib (PCI-32765) in B-cell Receptor Pathway Inhibition in CLL
Acronym
IciCLLe
Study hypothesis
The aim of this feasibility study is to confirm the mechanism of action of Ibrutinib. Results will then inform the design of a randomized phase II/III trial using response as the primary outcome measure to determine whether Ibrutinib shows sufficient evidence of activity in these cohorts of patients.
