Jounce Therapeutics to Present Nonclinical Translational Data at the 2018 American Association for Cancer Research (AACR) Annual Meeting

CAMBRIDGE, Mass., April 12, 2018 -- Jounce Therapeutics, Inc. (NASDAQ:JNCE), a clinical-stage company focused on the discovery and development of novel cancer immunotherapies and predictive biomarkers for patient enrichment, today announced that its nonclinical translational data will be presented in two posters at the 2018 American Association for Cancer Research (AACR) Annual Meeting in Chicago, Illinois from April 14-18, 2018.  

“The data presented at AACR for gastric cancer and triple negative breast cancer provides an example of the way in which we use the Jounce Translational Science Platform to interrogate the cellular microenvironment within the tumor to explore potential biomarkers. These data, focused on our ICOS agonist antibody program, JTX-2011, help inform our clinical development strategy,” said Deborah Law, D. Phil., chief scientific officer of Jounce Therapeutics.

About JTX-2011
Jounce’s lead product candidate, JTX-2011, is a monoclonal antibody that binds to and activates ICOS, a protein on the surface of certain T cells. Preclinical data support that JTX-2011 may have a dual mechanism of action that stimulates anti-tumor T effector cells, and also reduces the immunosuppressive T regulatory cells in the tumor microenvironment. The company is developing JTX-2011 to treat solid tumors as a single agent and in combination with other therapies.
