  • Patent number: 11951173
    Abstract: An antibody-drug conjugate (ADC) or a pharmaceutically acceptable salt thereof, is provided. The ADC includes a tetravalent monoclonal antibody conjugated to a cytotoxic drug by a chemical linker. The monoclonal antibody includes two long chains and four short chains. Each of the long chains includes a first segment and a second segment, the first segment located proximal to the N-terminus of the long chain, and the second segment located proximal to the C-terminus of the long chain. Each of the first segment and second segment pairs with one of the short chains to form an antigen-binding fragment domain, therefore forming four antigen-binding fragment domains having specificity toward the same antigen. Pharmaceutical composition including the ADC and methods of treating diseases using the compositions are also provided.

  • Publication number: 20130305396
    Abstract: Provided herein are rodents that express the human endosialin gene. In preferred embodiments, the rodent is a mouse. Preferably, the human endosialin gene is integrated into the native or endogenous endosialin gene locus. More preferably, the host rodent is null for the endogenous endosialin gene product. The human endosialin gene is preferably expressed in a similar development and disease response pattern as that of the native endosialin gene product in parental or wild type rodents. This feature makes these rodents useful for studying the effects of test agents to positively or negatively affect endosialin biology for therapeutic use. Use of human endosialin expressing rodents lacking native endosialin gene product (HUE rodents) is proposed as a strategy for developing agents that can positively or negatively affect the endosialin pathway and also serve as a screening tool to identify those agents that may be useful as human therapies.
