Conclusions B7H4 and 4–1BB expression in cancer cells, PBMC and solid tumors, together with robust B7H4-dependent single agent activity of CLN-418 in preclinical tumor models, support the development of CLN-418 in patients with difficult-to-treat solid cancers. A Phase 1 dose-escalation trial of CLN-418 is ongoing (NCT05306444).
