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.

Clinical methods for use of a PD-L1-binding molecule comprising a Shiga toxin effector

Provided herein are multivalent CD20-binding molecules, and compositions thereof, for use in selective killing of specific cell types and/or as therapeutics for the treatment of a variety of diseases, including cancer, tumors, and immune disorders. Certain multivalent CD20-binding molecules can be used to deliver agents into CD20-expressing cells, collecting diagnostic information, and/or monitoring the treatment of diseases, such as cancers, tumors, and immune disorders.

Multivalent CD20-binding molecule comprising Shiga toxin A subunit effector polypeptides and enriched compositions thereof

The present invention provides multivalent CD20-binding molecules and compositions thereof, such as enriched compositions comprising large proportions of multivalent CD20-binding molecules relative to monovalent CD20-binding molecules. Certain multivalent CD20-binding molecules of the present invention comprise (i) two or more CD20-binding regions and (ii) one or more Shiga toxin effector polypeptide regions derived from an A Subunit of a member of the Shiga toxin family. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for selective killing of specific cell types and as therapeutics for the treatment of a variety of diseases, including cancers, tumors, and immune disorders. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for delivering agents into CD20-expressing cells, collecting diagnostic information, and monitoring the treatment of a variety of diseases, such as cancers, tumors, and immune disorders which involve CD20-expressing cells.

Multivalent CD20-binding molecules comprising Shiga toxin a subunit effector regions and enriched compositions thereof

The present invention provides multivalent CD20-binding molecules, and compositions thereof, such as enriched compositions comprising large proportions of multivalent CD20-binding molecule relative to monovalent CD20-binding molecule. Certain multivalent CD20-binding molecules of the present invention comprise 1) two or more CD20 binding regions and 2) one or more Shiga toxin effector polypeptide regions derived from an A Subunit of a member of the Shiga toxin family. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for selective killing specific cell types and as therapeutics for the treatment of a variety of diseases, including cancers, tumors, and immune disorders. Certain multivalent CD20-binding molecules of the present invention, and compositions thereof, have uses for delivering agents into CD20-expressing cells, including for the intracellular labeling of CD20-expressing cells, collecting diagnostic information, and monitoring the treatment of variety diseases, such as cancers, tumors, and immune disorders which involve CD20-expressing cells.
