Curis Presents Early Clinical Pharmacokinetic And Biomarker Data From CA-170's Phase 1 Trial At The SITC 2016 Conference

LEXINGTON, Mass., Nov. 09, 2016 (GLOBE NEWSWIRE) -- Curis, Inc. (Nasdaq:CRIS), a biotechnology company focused on the development and commercialization of innovative and effective drug candidates for the treatment of cancer, today presented preliminary clinical pharmacokinetic (PK) and early biomarker data from the ongoing dose escalation stage of CA-170's Phase 1 trial at the Society for Immunotherapy of Cancer (SITC) 31 st Annual Meeting & Associated Programs in National Harbor, MD. CA-170 is a potent and selective, orally available small molecule antagonist of the programmed death ligand-1 (PDL1) and V-domain Ig suppressor of T cell activation (VISTA) immune checkpoints.

CA-170 is the first orally available small molecule immune checkpoint antagonist to be investigated in cancer patients. Preclinical data presented previously demonstrated dose-dependent oral exposure in multiple non-clinical models, as well as immune modulation and anti-tumor activity with CA-170 in multiple syngeneic mouse tumor models.  Clinical data from a limited number of patients in the Phase 1 trial presented at the SITC conference, demonstrate that similar to the preclinical findings, CA-170 has a dose proportional and predictable PK profile in patients treated orally at various doses in the ongoing dose escalation stage of the study.  Further, evaluation of patient blood samples demonstrate that CA-170 appears to be biologically active in modulating the immune system, with a several-fold increase in percentage of circulating CD8+ T cells expressing activation markers within 24 hours of oral dosing.

The clinical findings were presented in an oral session at SITC by David Tuck, MD, Chief Medical Officer of Curis.  Additional details will be presented during the conference at a poster session on Friday, November 11 at 12:15pm. In addition to the CA-170 data, Curis's collaborator, Aurigene will also present pre-clinical data from the PDL1/ T-cell immunoglobulin and mucin domain containing protein-3 (TIM-3) program at a poster session on Saturday, November 12 at 11:45am.
