Multispecific immune engagers for tumor microenvironment reprogramming
Introducing novel multispecific immune engagers designed to reprogram the immunosuppressive tumor microenvironment by recruiting and activating immune cells, enhancing immune surveillance and therapeutic efficacy in solid tumors like glioblastoma.
Overview
This innovative research at Purdue University presents multispecific immune engagers aimed at reprogramming the immunosuppressive tumor microenvironment (TME). These engagers are engineered to not only target tumors but also recruit immune cells through the localized release of chemokines, enhancing immune surveillance via a multi-modal approach. This technology addresses the challenge of impaired immune activity in solid tumors, such as glioblastoma, by activating immune responses and inhibiting immunosuppression.
Technical specifications
Key features:
- Multispecific design targeting tumors and recruiting immune cells
- Localized chemokine release, such as CXCL10, to promote immune cell recruitment
- Activation of immune responses through cell-intrinsic mechanisms
- Potential to enhance effector cell presence and activity in tumors
Applications:
- Treatment of solid tumors, including glioblastoma
- Reprogramming of the tumor microenvironment to enhance immune surveillance
- Potentially applicable in combination with other immunotherapies for improved efficacy
Technology readiness level
The technology is currently at TRL 4, having shown promising preliminary data. Future validation plans include adoptive transfer studies and engager immunotherapy testing in patient-derived models of intracranial glioblastoma using humanized mice. The anticipated outcomes include establishing efficacy, anti-tumor activity, and immune cell recruitment and activation. The study aims to support an IND filing within a year.
About Purdue University
Purdue University is a comprehensive public land‑grant research institution in West Lafayette, Indiana, anchored by a large residential campus. Industry engages through co‑located core facilities, pilot‑scale testbeds, and an adjacent innovation district that brings together labs, corporate R&D space, and maker resources near faculty talent. A statewide Extension network and an established engineering co‑op program connect companies to field sites, workforce pipelines, and pragmatic pathways from concept to deployment across Indiana. Research is supported by competitive federal funding from NSF, DOE, USDA, NIH, and the Department of Defense, and commercialization is managed by a dedicated technology transfer office in partnership with the university’s affiliated research foundation.
