Experimental: Pembrolizumab and Ibrutinib
Pembrolizumab intravenously (IV): 200 mg every 3 weeks (Q3W).
Ibrutinib by mouth (PO): Phase I Dose Escalation at doses of 420 mg daily (cohort 0) and 560 mg daily (cohort 1);. Phase II treatment at Recommended Phase II dose.
200 milligrams of pembrolizumab will be given through an IV (intravenously) for about thirty minutes. Pembrolizumab is an anti-PD1 that functions by inhibiting checkpoint inhibition and reversing T cell suppression.
Other Name: Keytruda®
Ibrutinib oral capsules every day starting on cycle 1, day 1. Ibrutinib is primarily a BTK inhibitor which has been approved for the treatment of several hematologic malignancies.
Other Name: Imbruvica®
- Phase I - Recommended Phase II Dose (RP2D) [ Time Frame: 42 days post first dose ]Standard 3+3 Design: The first cohort will enroll a minimum of 3 participants, according to a standard 3+3 design. If 0 out of the first 3 participants in the first cohort experience a dose-limiting toxicity (DLT), then dose escalation will continue as planned. If 1 out of the first 3 participants experience a DLT, then the cohort will be expanded to a total of 6 participants, and if no more than 1 out of 6 participants experiences a DLT in a given dose cohort, dose escalation will continue as planned. If ≥ 2 DLTs are observed in the first dose cohort, the principle investigator will discuss with Janssen on how to proceed. The DLT evaluation period will be defined as the time from the first dose of pembrolizumab and ibrutinib to 42 days after the first dose or if a participant experiences a DLT within this time period. A maximum of 2 cohorts is expected, making a total of approximately 12 evaluable participants during the dose escalation phase.
- Phase II - Disease Control Rate at 4 Months [ Time Frame: 4 months ]Complete Response (CR) + Partial Response (PR) + Stable Disease (SD). Tumor response by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 and RECIST based immune-related response criteria (irRC).
