Urelumab: Difference between revisions

Urelumab (also known as BMS-663513 or anti-4-1BB antibody) is a fully human IgG4 monoclonal antibody. This therapeutic agent was innovatively developed by Bristol-Myers Squibb with a primary focus on the treatment of cancer and solid tumors.

Mechanism of Action[edit]

The core mechanism of urelumab lies in its targeting capability. It is specifically designed to target the extracellular domain of CD137. Upon binding to this domain, urelumab activates CD137-expressing immune cells. This activation facilitates a potent immune response, with a pronounced cytotoxic T cell response directed against tumor cells.

Clinical Development[edit]

The developmental journey of urelumab in clinical trials has been incremental:

The first phase I trial was initiated in 2006, culminating with the publication of its final results in 2015.
Modern clinical trials have ventured to combine urelumab with other therapeutic agents and treatments:
- Chemotherapy: (NCT00351325)
- Chemoradiation: (NCT00461110)
- Ipilimumab: (NCT00803374)
- Rituximab: (NCT01775631, NCT02420938)
- Cetuximab: (NCT02110082)
- Elotuzumab: (NCT02252263)
- Nivolumab: (NCT02253992)

These combinations are being studied across multiple cancers such as metastatic solid tumors, NSCLC, melanoma, B-cell non-Hodgkin lymphoma, colorectal cancer, and multiple myeloma.

Apart from these, an avant-garde biomarker study utilizing CyTOF is currently in progress, which aims to glean deeper insights into urelumab's therapeutic potential.

Conclusion[edit]

Urelumab symbolizes a promising stride in the domain of oncology therapeutics. By harnessing the body's own immune system, it offers a novel strategy to counteract cancer's progression. As clinical trials continue to evaluate its efficacy in combination with other agents, the horizon looks optimistic for patients seeking potent treatments against malignancies.
