Allocation: Non-Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Name: Ibrutinib Type: Drug
Name: Carfilzomib Type: Drug
Name: Placebo Type: Drug
Name: Dexamethasone Type: Drug
Overall Status
Phase 1 is a dose escalation study to evaluate the safety and recommended Phase 2b dose of ibrutinib in combination with carfilzomib with and without dexamethasone.

Phase 2b will be a randomized, double-blind, placebo controlled study to evaluate the efficacy of ibrutinib and carfilzomib with or without dexamethasone.
Detailed Description
Bruton's tyrosine kinase (Btk) is an enzyme that is present in hematopoietic cells other than T cells and is necessary for downstream signal transduction from various hematopoietic receptors including the B cell receptor as well as some Fc, chemokine, and adhesion receptors, and is crucial for both B cell development and osteoclastogenesis. Although down-regulated in normal plasma cells, Btk is highly expressed in the malignant cells from many myeloma patients and some cell lines. PCI-32765 is a potent and specific inhibitor of Btk currently in Phase 2 and 3 clinical trials. The current study is designed and intended to determine the safety and efficacy of PCI-32765 in combination with carfilzomib (Kyprolis™) with and without dexamethasone in subjects with MM.
