Abstract: The present invention relates to antibody-drug conjugates (ADCs) wherein a plurality of active agents are conjugated to an antibody through at least one branched linker. The branched linker may comprise a branching unit, and two active agents are coupled to the branching unit through a secondary linker and the branching unit is coupled to the antibody by a primary linker. The active agents may be the same or different. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g., 2-4 branched linkers, which may each be coupled to a different C-terminal cysteine of a heavy or light chain of the antibody. The branched linker may comprise one active agent coupled to the branching unit by a first branch and a second branch that comprises a polyethylene glycol moiety coupled to the branching unit. In certain such embodiments, two or more such branched linkers are conjugated to the antibody, e.g.

Abstract: Provided are methods for manufacturing a conjugate containing a phthalocyanine dye, including methods that include one or more steps of preparing or producing the conjugate, formulating the conjugate and packaging the conjugate. In some aspects, the manufacturing methods result in the generation of a stable conjugate. Also provided are stable phthalocyanine dye conjugates, compositions and articles of manufacture containing the stable 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: An antibody-drug conjugate (ADC) has a structure represented by Formula (I): [D2-L2-Cn2yG2-Ab-Sg1G1-L1-D1]x?? Formula (I) or a pharmaceutically acceptable salt thereof, wherein Ab is an antibody without glycans (i.e., the protein portion of an antibody); G1 and G2 are glycan moieties, which may be the same or different; Cn1 and Cn2 are conjugation moieties, which may be the same or different; L1 and L2 are linker moieties, which may be the same or different; D1 and D2 are drug units which may be the same or different; and x and y are independently an integer from 0 to 8, provided that x+y?0.
Abstract: Lung cancer can be detected by measuring sites in pancreatic ribonuclease 1 (also abbreviated as “RNase 1”), wherein each of the sites is a site capable of being modified with an N-linked sugar chain. Lung cancer is detected by measuring items A and B as mentioned below and then comparing the ratio of the value of A to the value of B: A=the amount of sites in pancreatic ribonuclease 1, wherein the sites are sites each capable of being modified with an N-linked sugar chain and each having an N-linked sugar chain bound thereto or each having an N-linked sugar chain unbound thereto; and B=the amount of sites in pancreatic ribonuclease 1, wherein the sites are sites each capable of being modified with an N-linked sugar chain.
Abstract: The present invention discloses anti-PD-L/PD-1 Axis antibody conjugates for targeted immunotherapy, as well as compositions comprising said conjugates. Further, the present invention discloses the use of the conjugates in the treatment of tumor/cancer.
Abstract: The present invention provides novel peptide sequences for use in microbial transgluatminase-mediated, in particular mTG2-mediated bioconjugations, in particular for the manufacture of antibody-drug-conjugates. Further disclosed are bioconjugation methods employing mTG2 and the novel peptide sequence motifs of the invention. The present invention further provides proteins comprising the novel sequence motifs of the invention as well as polynucleotides encoding the same.

Abstract: This invention relates to novel analogs of the DNA-alkylating agent CC-1065 and to their conjugates. Furthermore this invention concerns intermediates for the preparation of said agents and conjugates. The conjugates are designed to release their (multiple) payload after one or more activation steps and/or at a rate and time span controlled by the conjugate in order to selectively deliver and/or controllably release one or more of said DNA alkylating agents. The agents, conjugates, and intermediates can be used to treat an illness that is characterized by undesired (cell) proliferation. As an example, the agents and the conjugates of this invention may be used to treat a tumor.
