CAMBRIDGE, Mass., April 03, 2019 (GLOBE NEWSWIRE) -- Jounce Therapeutics, Inc. (NASDAQ: JNCE), a clinical-stage company focused on the discovery and development of novel cancer immunotherapies and predictive biomarkers, today reported data on JTX-8064, its first tumor-associated macrophage program, at the 2019 American Association for Cancer Research (AACR) Annual Meeting in Atlanta, GA. The poster presentation includes preclinical data demonstrating the immunotherapeutic properties of JTX-8064 to reprogram immune-suppressive macrophages within the tumor microenvironment.
“Today, we presented the characterization of JTX-8064 and the preclinical data for this novel product candidate, demonstrating its potential in re-programming tumor-associated macrophages within the tumor microenvironment to enhance anti-tumor immunity. We believe that LILRB2 functions as an immune checkpoint for macrophages and have demonstrated differentiation from other macrophage-directed approaches,” said Elizabeth Trehu, M.D., chief medical officer of Jounce Therapeutics. “New insights from our Translational Science Platform continue to inform JTX-8064 development and we expect to file an Investigational New Drug application and initiate a Phase 1 clinical trial later this year.”
In a poster titled “Preclinical evaluation of JTX-8064, an anti-LILRB2 antagonist antibody, for reprogramming tumor-associated macrophages,” Jounce researchers describe the preclinical evaluation of JTX-8064 including:
The poster is available on the “Our Approach” section of the Jounce Therapeutics website at www.jouncetx.com.
JTX-8064 is an anti-Leukocyte Immunoglobulin Like Receptor B2 (LILRB2) antibody and is the first candidate to emerge from Jounce’s Translational Science Platform efforts that focuses on tumor-associated macrophages. Preclinical data presented at the 2019 AACR Annual Meeting supports the development of JTX-8064 as a novel immunotherapy to reprogram immune-suppressive macrophages and enhance anti-tumor immunity. JTX-8064 is currently in IND-enabling activities and Jounce anticipates filing an IND and initiating a Phase 1 clinical trial for JTX-8064 in 2019.
