PD-1(L1)/VEGF BsAbs like ivonescimab represent a novel therapeutic strategy with potential for improved efficacy and mitigated toxicity compared to combination therapies. Ongoing trials will define broader applications.
In addition, Sphyder biosensors revealed previously unrecognized mechanisms of the PD-1/VEGF bispecific antibody Ivonescimab, showing that it induces VEGF-dependent clustering, phosphorylation, and degradation of PD-1. These findings may underlie its promising clinical activity relative to conventional PD-1 blockade. Together, our study establishes a broadly applicable strategy for sensing and reprogramming cell signaling, while also providing mechanistic insights into a new class of immune checkpoint inhibitors of major clinical interest.
