Expert Systems Expands Partnership with Eilean Therapeutics and Joins Its Best-in-Class PTPN2 Inhibitor Program

ROCKVILLE, Md., March 12, 2024 /PRNewswire/ -- Expert Systems, a leader in AI-enabled drug discovery, announces the expansion of the collaboration with Eilean Therapeutics as it joins its new PTPN2 inhibitor program, which Eilean has recently acquired from Ness Therapeutics Inc (Ness) in an all-equity transaction.

"Eilean's lead PTPN2 inhibitor molecules demonstrate exceptional efficacy, selectivity, oral bioavailability and a good safety profile," commended Bill Farley, CBO at Expert Systems. "We're proud to be Eilean's partner & leverage our cutting-edge AI platform to help advance a new pipeline of best-in-class immuno-oncological therapy solutions with an improved safety and tolerability profile."

About Eilean Therapeutics' PTPN2 Inhibitor Program

Protein tyrosine phosphatase non-receptor type 2 (PTPN2), also known as T cell protein tyrosine phosphatase (TC-PTP), is ubiquitously expressed, primarily in hematopoietic and placental cells. As a critical negative regulator of the JAK-STAT pathway, PTPN2 functions to directly regulate signaling through cytokine receptors, including IFN?. Thus, enhancing IFN? sensing and signaling through the inhibition of PTPN2 is a potential therapeutic strategy to improve the efficacy of cancer immunotherapy regimens.
