HCB303 received FDA IND clearance
“We believe TIGIT-Fc offers a biologically superior strategy to conventional anti-TIGIT receptor blockade,” said Scott Liu, PhD, Founder and Chairman of HanchorBio. “Simply blocking PVR signaling through an anti-TIGIT antibody may release the inhibitory signal, but it does not address the down-regulation of CD226, which is needed for enhanced activation of T and NK cells. HCB303 was designed to go further—intercepting immune-inhibiting TIGIT ligands and preserving the CD226 activating axis, while simultaneously blocking the PD-L1 and CD47 pathways. This is precisely the type of biology-driven therapeutic architecture our FBDB™ platform was built to create.”

“Our team’s outstanding execution has enabled us to rapidly advance three programs into the clinic in 2026 and make significant progress in developing next-generation IO, ADC and combination therapies. Together with our partner, Kelun-Biotech, we have achieved seven IND clearances to date, and by mid-2027, we expect more than 2,000
