Overview
**T3P-Y058-739 + pembrolizumab** is an investigational combination therapy for advanced solid tumors. **T3P-Y058-739** is a genetically-modified, live attenuated strain of *Yersinia enterocolitica*, engineered to deliver therapeutic proteins into tumor cells via a type III secretion system (T3SS). This enables direct engagement and activation of the immune system through localized cytokine induction, promoting infiltration and activation of immune cells in the tumor microenvironment. The combination is being evaluated with **pembrolizumab**, a programmed cell death protein 1 (PD-1) checkpoint inhibitor, to potentially enhance anti-tumor immune responses by both mechanisms. The combination is under investigation in a phase I/II modular clinical study for patients with advanced solid malignancies[1][2][3][4][5][10].
