“Our CAPTN-3 tri-specific antibody platform is differentiated not only by its masked CD3 arm for conditional T cell activation, but also by the addition of an NKG2A arm for additional T cell and NK cell activation, and a third arm targeting the tumor-associated antigen. This approach is supported by other masked TCEs showing early safety and efficacy signals,” stated Purple Biotech (PPBT) CEO Gil Efron. “We are focusing our activities on advancing IM1240, our first CAPTN-3 antibody, through IND-enabling studies, with the goal of initiating a Phase 1 study in 2026. Additionally, we have now established a clear path forward for CM24 for its Phase 2b study, utilizing the predictive biomarkers we observed in the Phase 2 trial, and we are seeking partners or investment to support this next study.”
