Summary

Tucotuzumab celmoleukin (also known as EMD 273066 or huKS-IL2) is an immunocytokine consisting of a humanized anti-EpCAM IgG1 antibody fused to IL-2. It was investigated in clinical trials for EpCAM-positive solid tumors, particularly ovarian cancer, small-cell lung cancer, and other carcinomas, with the goal of concentrating IL-2 activity at the tumor site to reduce systemic toxicity while enhancing local anti-tumor immunity.

Mechanism of Action

Tucotuzumab celmoleukin is a fusion protein combining an anti-EpCAM humanized monoclonal antibody (tucotuzumab) with interleukin-2 (celmoleukin/IL-2). It targets EpCAM-expressing tumor cells, delivering IL-2 to the tumor microenvironment to stimulate local T-cell and NK-cell proliferation and cytotoxic activity, thereby enhancing anti-tumor immune responses.
