Brief Summary:
The purpose of this study is to determine the safety and tolerability, describe the dose-limiting toxicities (DLTs), and determine the maximum tolerated dose (MTD) (or the highest protocol-defined dose level in the absence of establishing an MTD) of ibrutinib in combination with pembrolizumab in participants with advanced, refractory colorectal cancers.

Condition or disease Intervention/treatment Phase
Colon Cancer Colorectal Cancer Colorectal Carcinoma Colon Disease Drug: Pembrolizumab Drug: Ibrutinib Phase 1 Phase 2

Detailed Description:
On this study, one treatment cycle equals 21 days. On the first day of each study treatment cycle, 200 milligrams of pembrolizumab will be given through an IV (intravenously) for about thirty minutes. In addition, participants will begin taking the ibrutinib capsules every day starting on cycle 1, day 1. Participants will have a follow-up visit every 3 weeks, on about the first day of each cycle with laboratories drawn to make sure that the study drugs are not causing any side effects. In addition, participants will have a computed tomography (CT) scan every 6 to 7 weeks to determine whether your cancer is getting better or worse.

Arm Intervention/treatment
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.

Drug: Pembrolizumab
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®

Drug: Ibrutinib
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®

Primary Outcome Measures :
  1. 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.

  2. Phase II - Disease Control Rate at 4 Months [ Time Frame: 4 months ]
    Percentage of participants who achieved disease control at 4 months. Disease control rate = 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).

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histologically confirmed diagnosis of colorectal adenocarcinoma.
  • Measurable or non-measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. Stage IV or recurrent disease is required.
  • Participants must have received and progressed through or become intolerant to fluoropyrimidine, irinotecan, oxaliplatin, and bevacizumab. If RAS wild type, participants should have received and progressed or become intolerant to the above as well as cetuximab or panitumumab containing therapies. Prior therapy with Regorafenib and/or TAS 102 is allowed.
  • Eastern Cooperative Oncology Group (ECOG) Performance Score 0 or 1.
  • Estimated life expectancy > 3 months.
  • Adequate bone marrow, liver and renal function as assessed by the following:

    • Hemoglobin > 8.0 g/dl
    • Absolute neutrophil count (ANC) > 1,000/mm^3 independent of growth factor support
    • Platelet count > 100,000/mm^3
    • Total bilirubin < 1.5 times upper limit of normal (ULN) unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin
    • AST, ALT and Alkaline Phosphatase ≤2.5 times the ULN ( ≤5 x ULN for potential participants with liver involvement)
    • Creatinine clearance ≥ 30 ml/min
  • Must not have had chemotherapy, major surgery, monoclonal antibody therapy or experimental therapy within the 21 days prior to the start of ibrutinib administration
