Urelumab targets the extracellular domain of CD137.[2] It specifically binds to and activates CD137-expressing immune cells, stimulating an immune response, in particular a cytotoxic T cell response, against tumor cells.[3]

The first phase I trial began in 2006 and final results were published in 2015.[4]

Current clinical trials combine urelumab with chemotherapy (NCT00351325), chemoradiation (NCT00461110), ipilimumab (NCT00803374), rituximab (NCT01775631, NCT02420938), cetuximab (NCT02110082), and elotuzumab (NCT02252263), nivolumab (NCT02253992) for metastatic solid tumors, NSCLC, melanoma, B-cell non-Hodgkin lymphoma, colorectal cancer, and multiple myeloma. A biomarker study using CyTOF is also underway.[2]
