Cytokine factories activate innate and adaptive immune cells domestically to elicit antitumor efficacy in mice. Credit score: Journal for ImmunoTherapy of Most cancers (2025). DOI: 10.1136/jitc-2024-010685
A crew of researchers from the Rice Biotech Launch Pad at Rice College has developed an implantable “cytokine factory” that safely triggers potent immune responses in opposition to hard-to-treat cancers, together with metastatic melanoma, pancreatic and colorectal tumors.
The examine, revealed within the Journal of ImmunoTherapy of Most cancers, particulars how an immunoprotected gadget close to the tumor microenvironment containing cells engineered to domestically launch interleukin-12 (IL-12)—an “IL-12 cytokine factory”—efficiently induces the recruitment of specialised immune cells referred to as precursor exhausted T cells (Tpex cells).
This Tpex cell recruitment leads to a big, sturdy inhabitants of tumor-targeting T cells with broad molecular profiles, each in isolation and in an enhanced method when carried out together with different immunotherapy approaches.
The IL-12 cytokine factories together with checkpoint inhibitors efficiently eradicated native and distal tumors in preclinical fashions of metastatic melanoma and colorectal and pancreatic cancers. Along with this sturdy efficacy sign, the IL-12 cytokine manufacturing unit demonstrated security in each mouse and nonhuman primate fashions.
This revealed analysis will function the inspiration for an investigational new drug software (IND) with the U.S. FDA in early 2026, and RBL LLC expects to launch an rising biotech firm centered on the groundbreaking IL-12 cytokine manufacturing unit expertise.

“We designed the IL-12 cytokine factory to enhance immunotherapy approaches while minimizing toxicity, a critical need in the treatment of particularly aggressive cancers,” mentioned Omid Veiseh, professor of bioengineering, college director of the Rice Biotech Launch Pad and senior corresponding creator of the publication.
“IL-12 is particularly impactful compared to other cytokines, as our research demonstrates that other cytokines primarily recruit homogeneous T cell populations and show reduced efficacy over time, while IL-12 generates a more robust antitumor response by recruiting a more durable, broader repertoire of tumor-targeting T cells. We are hopeful that this technology will significantly impact the lives of cancer patients by enhancing the efficacy of immunotherapy approaches in the clinic.”
“Harnessing the cellular immune system to target solid tumors is a common but often fraught approach to fighting cancer as the associated challenge of efficacious treatment without toxicity remains elusive,” mentioned Nathan Reticker-Flynn, assistant professor of otolaryngology at Stanford College.
“Our study demonstrates not only the efficacy of this technology in preclinical models but also its safety profile, which is a critical aspect as we move toward clinical trials. This research represents an important step forward in the quest to provide more effective treatments for patients battling metastatic cancers.”
