(“Acrivon” or “Acrivon Therapeutics”) (Nasdaq: ACRV), a clinical stage biotechnology company discovering and developing precision medicines utilizing its proprietary Generative Phosphoproteomics AP3 (Acrivon Predictive Precision Proteomics) platform deployed for rational drug design and predictive clinical development, today announced three poster presentations, including one late-breaking presentation, at the upcoming American Association for Cancer Research (AACR) Annual Meeting being held in San Diego, CA from April 17-22, 2026. “These data further demonstrate our differentiated approach leveraging our AP3 platform to identify therapeutic candidates and combinations with the greatest potential for clinical impact,” said Peter Blume-Jensen, M.D., Ph.D., chief executive officer, president, and co-founder of Acrivon. “Our data show that a key resistance mechanism to Topo1 inhibitors, the most common ADC payload, is the activation of the CHK1/2 DNA damage repair response, which can be overcome by ACR-368 treatment resulting in synergistic tumor cell killing. We also found that ACR-2316 induced mitochondrial and nuclear genomic damage resulting in activation of the innate and adaptive immune system, leading to complete tumor regression and lasting immune protection in mice when combined with immune checkpoint inhibition.” Poster Details: TitlePotent synergy between CHK1/2 inhibitor ACR-368 and the ADC payload topoisomerase 1 inhibitor: Rationale for ADC + ACR-368 combination therapyDate and TimeSunday, April 19, 2026; 2:00 p.m. - 5:00 p.m. PTSessionExperimental and Molecular Therapeutics: DNA Damage and Repair 1Poster Number 239 TitleACR-368 synergizes with PD-L1 blockade by coordinated activation of adaptive and innate immunity pathways to achieve robust anti-tumor efficacyDate and TimeMonday, April 20, 2026; 9:00 a.m. - 12:00 p.m. PTSessionLate...
