Abstract: Provided herein are compounds, compositions, conjugates and methods for the treatment of diseases, and/or conditions such as, but not limited to, proliferative diseases. In certain embodiments, compounds, compositions, and conjugates are provided, which include cyclodextrin-based linker-payloads and protein conjugates thereof, and/or in combination with other agents. By administering these compounds, compositions, and conjugates as described herein to specific target cells, side-effects due to non-specific binding phenomena, for example, to non-target cells are reduced.

Abstract: Provided herein are bispecific antigen-binding molecules that bind HER2 and methods of use thereof. The bispecific antigen-binding molecules comprise a first and a second antigen-binding domain, wherein the first and second antigen-binding domains bind to two different (preferably nonoverlapping) epitopes of the extracellular domain of human HER2. The bispecific antigen-binding molecules cluster on the surface of HER2 IHC2+ and IHC3+ cells, and are internalized into the cellular lysosomes. Also included are antibody-drug conjugates (ADCs) comprising the antibodies or bispecific antigen-binding molecules provided herein linked to a cytotoxic agent, radionuclide, or other moiety, as well as methods of treating cancer in a subject by administering to the subject a bispecific antigen-binding molecule or an ADC thereof.

Abstract: Radiolabeled anti-PD-L1 antibodies and their use in immuno-PET imaging are provided herein. Included are methods of detecting the presence of PD-L1 proteins in a patient or sample.

Abstract: Described herein are protein steroid conjugates that are useful, for example, for the target-specific delivery of glucocorticoids (GCs) to cells.

Abstract: The present disclosure relates to VEGF antagonists. VEGF antagonists disclosed herein comprise a VEGF binding domain and a multimerization domain. Certain VEGF antagonists disclosed herein comprise five or more dimers, each dimer comprising two polypeptides, each polypeptide comprising a VEGF binding domain and a multimerization domain comprising an IgG Fc domain and, optionally, an IgM tailpiece. The disclosure further provides pharmaceutical compositions comprising the VEGF antagonists and methods of use of the VEGF antagonists in therapy, e.g., for treating angiogenic eye disorders. Also disclosed are nucleic acids encoding the VEGF antagonists, recombinant cells that express the VEGF antagonists, and methods of producing the VEGF antagonists.

Abstract: Provided herein are antibodies and antigen-binding fragments that bind MSR1 and methods of use thereof. According to certain embodiments, the antibodies bind human MSR1 with high affinity. In certain embodiments, the antibodies bind MSR1 without blocking, or blocking less than 90%, of modified LDL binding to MSR1. In some embodiments, the antibodies bind cell surface expressed-MSR1 and are internalized. The antibodies of the invention may be fully human antibodies. The invention includes anti-MSR1 antibodies, or antigen-binding fragments thereof, conjugated to drugs or therapeutic compounds.
