NEC Announces Interim Results from Phase 1 Clinical Trial of NECVAX-NEO1, an AI-Driven Personalized Oral Cancer Vaccine, at ESMO Immuno-Oncology Congress 2024 (NEC Corporation) - P1 | N=15 | NCT05354323 | "NEC Bio Therapeutics today presents 24-week promising interim results from an ongoing Phase 1 basket clinical trial of an orally administered cancer vaccine, NECVAX-NEO1, used in combination with checkpoint inhibitors (CPI) for treating patients with solid tumors. The findings are being presented in a poster at the ESMO Immuno-Oncology Congress in Geneva, Switzerland from December 11 to 13, 2024.... The safety run-in phase showed no treatment-related toxicities, allowing a dose increase. An ELISPOT response was induced by 68% of neoepitopes, with 40% of patients showing significant neoantigen-specific signals. After a 24-week treatment period, 80% of patients had a stable disease status, indicating a high disease control rate."
