Exicure to Present at the AACR Annual Meeting 2019

Two posters are being presented at the AACR Annual Meeting in Atlanta, Georgia
Exicure’s TLR9 agonist shows activation of NK cells and T cells in a Phase 1 clinical trial
Data presented in collaboration with Celldex show that Exicure’s technology leads to a more potent anti-tumor response when combined with Celldex’s CDX-301

SKOKIE, Ill.--()--Exicure, Inc. (OTCQB:XCUR), a pioneer in gene regulatory and immunotherapeutic drugs utilizing spherical nucleic acid (SNA™) constructs, will present pre-clinical and clinical data for its TLR9 immune system agonist, AST-008, in two poster sessions at the AACR Annual Meeting 2019 in Atlanta, Georgia from March 29 – April 03, 2019.

“On behalf of the Exicure team, we are pleased to announce these two posters which underscore the importance of Exicure’s SNA technology for immune therapy against cancer,” said Dr. David Giljohann, Chief Executive Officer of Exicure. “The first poster shows the high potency activation of effector immune cells by our immune system agonist AST-008 after administration of AST-008 to healthy volunteers in a Phase 1 clinical trial. In the second poster, we are pleased to share for the first time, work conducted in collaboration with Celldex Therapeutics showing that Exicure’s TLR9 agonist leads to improved anti-tumor response when combined with CDX-301,” said Dr. Giljohann.

The first poster, authored and presented by Exicure scientists, titled: "AST-008, a TLR9 agonist spherical nucleic acid, activated NK cells, T cells, and cytokines in healthy subjects in a Phase 1 clinical trial" demonstrates the utility of Exicure’s proprietary platform technology for targeting TLR9 to upregulate the immune system. Exicure’s drug, AST-008, is now enrolling patients in a Phase 1b/2 trial in patients with advanced solid tumors.

A second poster, to be presented by Celldex scientists, showcases data generated by Celldex Therapeutics, Inc. and Exicure through an ongoing scientific collaboration. The poster, titled: "Preclinical evaluation of the recombinant dendritic cell growth factor CDX-301 (Flt3L), and AST-008, a TLR9 agonist SNA” highlights improved anti-tumor activity after administration of AST-008 in combination with CDX-301.
