SystImmune to Present Updated Izalontamab Brengitecan Data for HER2-Negative Breast Cancer at ESMO Breast 2025
- SystImmune will present updated Phase 1 data on izalontamab brengitecan (iza-bren), a novel EGFRxHER3 bispecific antibody-drug conjugate, at ESMO Breast Cancer 2025 in Munich, Germany.
- The data shows encouraging efficacy across all HER2 levels in HER2-negative breast cancer patients, including HER2 0 patients, building on previously reported results at SABCS 2024.
- Iza-bren, jointly developed by SystImmune and Bristol Myers Squibb, demonstrates strong clinical efficacy with a manageable safety profile, potentially addressing significant unmet needs in breast cancer treatment.
