Abstract: Described are antibody peptide conjugates (APCs) comprising an antibody conjugated to a peptide analog of glucagon, which have been modified to be resistant to cleavage and inactivation by dipeptidyl peptidase IV (DPP-IV) and to increase in vivo half-life of the peptide analog while enabling the peptide analog to have agonist activity at the glucagon (GCG) receptor and the glucagon-like peptide 1 (GLP-1) receptor and the use of such APCs for treatment of metabolic disorders such as diabetes, non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and obesity.

Abstract: Antibody drug conjugates (ADCs) comprising an antibody conjugated to an anti-inflammatory therapeutic agent via a phosphate-based linker with tunable extracellular and intracellular stability are described.

Abstract: Provided are conjugates of the phthalocyanine dye IR700 and an EGFR-binding antibody, such as a cetuximab antibody, and pharmaceutical compositions thereof. In some aspects, the compositions contain an EGFR-binding antibody, such as a cetuximab antibody, that is modified by conjugation to the IR700 dye at specific positions within the heavy chain and/or the light chain of the cetuximab antibody. In some aspects, such conjugates are capable of targeted cell killing following irradiation of the conjugate Also provided are related methods of manufacture and methods of use and uses, including in treatments for tumors and specific-cancer indications.

Abstract: Provided are compositions containing a conjugate containing a phthalocyanine dye, including compositions containing stabilizing agents, such as non-ionic surfactants and/or protectants. In some aspects, the compositions result reduced aggregation of the conjugate due to agitation, temperature exposure, and/or pH. Also provided are articles of manufacture containing the compositions containing the conjugates, and methods for their administration to subjects for photoimmunotherapy. In some embodiments, the phthalocyanine dye conjugates are conjugated to a targeting molecule, such as an antibody, that targets the conjugate to a cell or pathogen, such as by binding to a cell surface protein.

Abstract: Phosphate-based linkers with tunable stability for intracellular delivery of drug conjugates are described. The phosphate-based linkers comprise a monophosphate, diphosphate, triphosphate, or tetraphosphate group (phosphate group) and a linker arm comprising a tuning element and optionally a spacer. A payload is covalently linked to the phosphate group at the distal end of the linker arm and the functional group at the proximal end of the linker arm is covalently linked to a cell-specific targeting ligand such as an antibody. These phosphate-based linkers have a differentiated and tunable stability in blood vs. an intracellular environment (e.g. lysosomal compartment).

Abstract: The present application discloses PEG modified variants of a bFGF-21 polypeptide, compositions containing a bFGF-21 polypeptide variant, and methods useful in treating and/or preventing ketosis that administer the variant or a composition containing said bFGF-21 variant.
