Study to Evaluate Ibrutinib Combination Therapy in Patients With Selected Gastrointestinal and Genitourinary Tumors

Inclusion Criteria:

RCC (clear cell), urothelial carcinoma (UC) (transitional cell), gastric or gastro-esophageal junctional (GEJ) adenocarcinoma, or K-RAS or N-RAS wild-type EGFR expressing CRC For cohort 1 RCC: minimum of 1 and maximum of 4 prior regimens, one or more of which must have included a VEGF-TKI For UC cohort 2: minimum of 1 and maximum of 2 prior regimens, one of which must have included a platinum-based regimen For UC cohort 5: Minimum of 1 and maximum of 2 prior regimens, one of which must have included a checkpoint inhibitor.

For UC cohort 6:

Locally advanced or mUC who are not eligible for cisplatin chemo with a PDL-1 score (CPS) of ≥ 10 without prior treatment.

Locally advanced or mUC who have progressed on platinum chemo or within 12 months of neo- or adjuvant therapy with a platinum chemotherapy. A minimum of 1 and maximum of 2 prior therapies.

For cohort 3 gastric or GEJ adenocarcinoma: minimum of 1 and maximum of 3 prior regimens one of which must have included a fluoropyrimidine regimen For cohort 4 CRC: minimum of 2 and maximum of 4 prior regimens, which must have included both an irinotecan and an oxaliplatin based regimen unless unable to tolerate irinotecan chemotherapy

Laboratory:

Adequate hematologic function:

Absolute neutrophil count ≥1500 cells/mm3 (1.5 x 109/L) Platelet count \>80,000 cells/mm3 (80 x 109/L) for cohort 1 (RCC) Platelet counts \>100,000 cells/mm3 (100 x 109/L) for all UC cohorts Hemoglobin ≥8.0 g/dL. for cohort 1 (RCC),all UC cohorts, and cohort 3 (GC) Hemoglobin ≥9.0 g/dL for cohort 4 (CRC)

Adequate hepatic and renal function defined as:

Serum aspartate transaminase (AST) and/or alanine transaminase (ALT) ≤5.0 x upper limit of normal (ULN) if liver metastases, or ≤3 x ULN without liver metastases Alkaline phosphatase \<3.0 x ULN or ≤5.0 x ULN if liver or bone metastases present Bilirubin ≤1.5 x ULN (unless bilirubin rise is due to Gilbert's syndrome or of non-hepatic origin, such as hemolysis) with the exception of subjects in the GC cohort where docetaxel is administered, these subjects must have bilirubin within normal limits (WNL) Estimated Creatinine Clearance ≥30 mL/min (Cockcroft-Gault)

Exclusion Criteria

Prior treatment with:

Everolimus or temsirolimus (RCC cohort 1) Any taxane (UC cohort of ibrutinib + paclitaxel) (cohort 2) Checkpoint inhibitors (UC cohort 6) Any taxane (GC cohort 3) Cetuximab or panitumumab (CRC cohort 4)

For all Cohorts:

Concomitant use of warfarin or other Vitamin K antagonists History of stroke or intracranial hemorrhage within 6 months prior to enrollment Major surgery within 4 weeks of first dose of study drug Requires treatment with strong CYP3A inhibitors known bleeding disorders or hemophilia

UC cohort 6 only:

Subjects who have an active, known or suspected autoimmune disease. Evidence of clinically significant interstitial lung disease or active, noninfectious pneumonitis.

Non-steroid immunosuppressive medications within 14 days before the first dose of ibrutinib and pembrolizumab.

Subjects in whom prior anti PD-1 / anti-PD-L1 therapy was intolerable and required discontinuation of treatment.
