HLX3902: A Trispecific T‑Cell Engager Rewiring the Immune Desert in Prostate Cancer
HLX3902 is a STEAP1×CD3×CD28 trispecific T‑cell engager developed as a potential first‑in‑class immunotherapy for prostate cancer. Prostate tumors are largely “cold” from an immunological standpoint. The microenvironment is immunosuppressive, T cells are scarce inside the tumor mass, and those that do infiltrate often burn out quickly after activation. Classical CD3‑only bispecific TCEs can force T […]
