Xenetic Biosciences, Inc. Presents Positive Preclinical Data Highlighting the Potential of Co-Administration of DNase I with CAR T Cells in a Murine Model of Melanoma Lung Metastasis
(Xenetic Biosciences Press Release)
- "The poster...was presented on behalf of the Company by Alexey Stepanov...at the AACR Special Conference in Cancer Research: Tumor-body Interactions: The Roles of Micro- and Macroenvironment in Cancer, held November 17-20, 2024, in Boston.....Key Highlights: Co-administration of single injection of DNase I (10 mg/kg) with murine EGFR-CAR T cells demonstrated to significantly suppress metastatic tumor burden, decreases the number of metastatic foci, and substantially prolongs survival compared to the CAR T cell monotherapy group; Degrading of NETs by DNase I increases the amount of tumor-infiltrating T and CAR T cells and reduces the immunosuppressive effects of the TME; Tumor immune cell infiltrate analysis revealed that the CD8 population of tumor-infiltrating CAR T cells from the DNase I treated group have lower expression of PD-1 and TIM-3 exhaustion markers."

Xenetic Biosciences, Inc. Presents Positive Data Demonstrating DNase I Significantly Improves Efficacy of Anti-CTLA-4 Immune Checkpoint Blockade in Preclinical Colorectal Carcinoma Models
(Xenetic Biosciences Press Release)
- "Data demonstrates beneficial effects of targeting NETs with systemic DNase I in models of primary tumor and metastatic CRC, improving the efficacy of CTLA-4 immune checkpoint blockade; Both published and newer data suggests that DNase I impedes neutrophil tumor infiltration, promotes CD4 and CD8 T cell infiltration, and enhances intratumoral T cell activation; DNase I plus 𝛼-CTLA-4 combination therapy results in tumor growth inhibition, several CRs and enhanced survival in mice bearing CT26 or Colon26 MSS/MMRp CRC tumors; Dose response evaluations of DNase I combined with 𝛼-CTLA-4, examining both route and frequency of administration was performed; DNase I plus 𝛼-CTLA-4 combination therapy resulted in complete responses (CRs) in mice bearing either CT26 or Colon26 tumors."
