Methods of Producing T-cell Populations Using P38 MAPK Inhibitors

Summary
Adoptive cell therapy (ACT) uses cancer reactive T-cells to effectively treat cancer patients. Producing many persistent T-cells is critical for successful treatments. Researchers at the National Cancer Institute (NCI) have developed a method of producing larger populations of minimally-differentiated T-cells. NCI seeks licensing and/or co-development research collaborations to further develop, evaluate, and/or commercialize this novel method of producing effective T-cell populations using p38 mitogen-activated protein kinase (MAPK) inhibitors.

Description of Technology

Adoptive cell therapy (ACT) uses cancer reactive T-cells to effectively treat patients. However, several obstacles inhibit the successful use of ACT for cancer treatment.  Current approaches for the expansion of T-cells may produce T-cells with a terminally differentiated phenotype that is associated with diminished anti-tumor activity and poor capacity for long-term persistence. Studies have shown that improving metabolic properties and persistence of T-cells during ex vivo expansion could improve anti-tumor efficacy of T-cells. Thus, there is a need for improved methods of obtaining an isolated population of effective T-cells for ACT. 

Researchers at the National Cancer Institute (NCI) have developed a method of producing larger populations of minimally-differentiated T-cells using p38 mitogen-activated protein kinase (MAPK) inhibitors. The researchers have identified p38 kinase as a key target molecule to preserve several desired qualities of T-cells while they are expanded prior to infusion in cancer patients. The researchers found that pharmacologic or genetic inhibition of p38 kinase improves expansion, metabolic properties, genomic stress, and cytolytic function of T-cells to clear tumors. P38 kinase serves as novel target that uncouples T-cell expansion to differentiation and enhances tumor clearance in adoptive cell transfer therapies for cancer.

The NCI Surgery Branch is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, and/or commercialize a novel method of producing effective T-cell populations using p38 MAPK inhibitors.
