Global Clinical Landscape & Future Outlook

The NRP1 therapeutic landscape is transitioning from pure anti-angiogenic strategies (VEGF blockade) to dual-mode immuno-oncology interventions targeting tumor-associated Tregs and macrophages. As first-generation monotherapies (e.g., anti-NRP1 mAbs) demonstrate limited efficacy as single agents, the R&D focus has shifted toward bispecific constructs (PD-1/NRP1) and ADCs leveraging NRP1's rapid internalization properties. The next wave of development emphasizes combination with VEGFR2 inhibitors and radioligand therapies for glioblastoma and metastatic colorectal cancer. As an essential co-receptor for VEGF and Semaphorin pathways, NRP1 plays a crucial role in tumor angiogenesis, immune evasion (Treg modulation), and viral entry, making it a promising target for synergistic pathway blockade to overcome anti-VEGF resistance and enhance immune checkpoint inhibitor efficacy in the tumor microenvironment.
