Data on Exicure’s TLR9 Agonist Spherical Nucleic Acid (SNA™) Construct Presented at the 4th CRI-CIMT-EATI-AACR International Cancer Immunotherapy Conference

Exicure technology shows effective antitumor activity in mouse tumor models

SKOKIE, Ill.--()--Exicure, Inc. (OTCQB:XCUR), the pioneer in gene regulatory and immunotherapeutic drugs utilizing three-dimensional, spherical nucleic acid (SNA™) constructs, presented data in a poster session on Sunday, September 30 at the 4th CRI-CIMT-EATI-AACR International Immunotherapy Conference: Translating Science into Survival in New York, New York.

The poster titled “AST-008, a novel TLR9 agonist SNA, induces abscopal antitumor effects in mouse tumor models” supports the ongoing clinical development of the Company's proprietary SNA™ technology and highlights new data showing the effects of Exicure’s technology on mouse tumor models through a systemic immune response.

These data presented in the poster session show that both subcutaneous and intra-tumoral administration of AST-008 into one tumor lesion in the mouse model leads to systemic antitumor activity at a distant, un-injected tumor.

These new data, along with data from other pre-clinical tumor model studies in combination with an anti-PD-1 antibody, and our recently completed Phase 1 trial support the continued advancement of Exicure's drug candidate AST-008,” said Dr. David Giljohann, Chief Executive Officer of Exicure. “We intend to launch our Phase 1b/2 clinical trial in combination with a checkpoint inhibitor in Q4 of 2018.”
