OUTLINE: This is a phase I, dose-escalation study of ibrutinib followed by a phase Ib study.
Patients receive ibrutinib orally (PO) daily on days 1-21 and pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 17 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 30 days, and then every 3 months for 2 years and every 6 months for 3 years.
