AACR 2025: Brenus Pharma Presents Late-breaking Preclinical Data on its “off-the-shelf” Next-generation Vaccine-based Immunotherapy Candidate, STC-1010, Now Moving to Clinic

STC-1010 addresses the need for effective therapies in microsatellite stable (MSS) colorectal cancer (CRC), a subtype with low immunogenicity and poor response to immune checkpoint inhibitors. (95% of CRC patients) The results demonstrate STC-1010’s ability to enhance activation of dendritic cells and CD8⁺ T cells, driving anti-tumor activity across multiple CRC models with high manufacturing reproducibility. Data support the advancement of STC-1010 to clinical Phase I/II evaluation in non-resectable or metastatic MSS and MSI-H CRC patients.

Brenus Pharma, a French clinical-stage biotechnology company, presented new preclinical data on its lead immunotherapy candidate, STC-1010, during the Late-Breaking Research: Immunology 3 session at the AACR Annual Meeting 2025, held April 25–30 in Chicago, IL.

George Alzeeb, PhD, Innovation Manager at Brenus Pharma, presenting the company’s latest preclinical data on STC-1010 — an off-the-shelf vaccine-based immunotherapy — during the Late-Breaking session at the American Association for Cancer Research (AACR) Annual Meeting 2025. This poster highlights the potential of STC-1010 to induce a robust anti-tumor response, supporting Brenus Pharma’s novel approach in immuno-oncology and clincial development.

The data highlight advances from Brenus Pharma’s proprietary Stimulated-Tumor-Ghost Cell (SGC) platform, a next-generation precision immuno-oncology approach showcasing its potential to initiate a robust anti-tumor response in colorectal cancer—a major unmet need in solid tumors.

Key findings demonstrate the reproducibility of STC-1010’s anti-tumor profile across multiple manufacturing batches and preclinical models (in vivo, in ovo, ex vivo) including those modified to be resistant to current immunotherapies. Dendritic cells showed increased antigen presentation and activation of CD8⁺ T cells with STC-1010, resulting in significant tumor cell apoptosis (tumor killing) and reduced metastasis.

“Immunotherapy was clearly a central focus at AACR 2025, with growing recognition across the scientific community that cancer vaccines are now a promising strategy for both treatment and prevention.” said George Alzeeb, PhD, Innovation Manager at Brenus Pharma. “We’re proud to be part of this momentum and look forward to the next steps.”
