Abstract

The present disclosure relates to PD-L1-binding molecules comprising a Shiga toxin effector region, a PD-L1-binding region, and a T cell epitope, and pharmaceutical compositions thereof. The PD-L1 binding molecules and pharmaceutical compositions thereof have uses for selectively killing specific cells (e.g., PD-L1 positive tumor cells and/or immune cells), for selectively delivering cargos to specific cells (e.g., PD-L1 positive tumor cells or immune cells), and as therapeutics for treating or slowing the progression of cancer (e.g., non-small cell lung cancer or squamous cell carcinoma of the head and neck). The present disclosure also relates to clinical methods for use of the disclosed PD-L1 binding molecules for treating a subject in need thereof.
