At the Annual Conference of the American Association for Cancer Research (AACR), in Orlando (Florida) from April 14th to 19th LYON, France--(BUSINESS WIRE)-- Brenus Pharma Announces two groundbreaking presentations on STC-1010, the company's first drug candidate for colorectal cancer (CRC), produced by Brenus Pharma's STC (Stimulated Tumor-Cells) Technology Platform. Innovative models for anti-tumor vaccine development were highlighted: Inovotion’s CAM (chorioallantoic model) in-ovo assay and Explicyte’s ex-vivo co-cultured assay, were used to characterize the mechanism of action through a specific immune response, and validate the anti-tumor effects of STC-1010. These models comply with the FDA’s modernization act 2.0 S. 5002 and demonstrate the potential of STC-1010 in clinical settings for the treatment of patients with colorectal cancer. The first study evaluated the safety and efficacy of STC-1010 in activating the antitumoral immune response against human colorectal adenocarcinoma using the chicken CAM assay. Results obtained in-ovo confirmed the anti-tumor efficacy -mediated by cytokine secretion and T cells expansion- of the vaccine previously observed in CRC syngeneic mouse models. Dendritic cells primed by STC-1010 will induce a multi specific pool of T-lymphocytes against the tumor without toxicity. The second study evaluated the functional activity of STC-1010-primed dendritic cells (DCs) from PBMCs human donors’ isolation, to activate autologous CD8+ T cells and promote tumor cell death. The study evaluated the cross-priming and specificity of the immune response induced by STC-1010. Results showed that STC-1010 is an efficient strategy to educate the immune system by cross-priming DCs and increasing the activity of specific CD8+ T cells (TCR sequencing) all of which promotes the significant tumor killing observed ex-vivo. Taken together, these studies provide promising results for the development of the STC-1010 and prove its potential to be presented into clinical setting for the treatment of patients with CRC. Innovative in vivo model for anti-tumor vaccine development: Safety validation and preliminary efficacy evaluation of a new antitumor vaccine STC-1010 on human colorectal adenocarcinoma using the chicken CAM assay.
