Patents by Inventor David M. Urech

David M. Urech has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9938336
    Abstract: The invention provides methods of using sequence based analysis and rational strategies to modify and improve the structural and biophysical properties of single chain antibodies (scFvs), including stability, solubility, and antigen binding affinity. These methods and strategies can be used individually or in combination. The methods of the present invention also include the use of a database comprising scFv sequences from an experimentally screened scFv library of antibodies that have been selected to have superior solubility and stability. The invention also provides methods of using the properties found for these selected antibodies in a general approach for reshaping scFv antibodies to improve stability and solubility properties of a single chain antibody fragment.
    Type: Grant

  • Patent number: 9315572
    Abstract: The present invention relates to particularly stable and soluble scFv antibodies and Fab fragments specific for TNF?, which comprise specific light chain and heavy chain sequences that are optimized for stability, solubility, in vitro and in vivo binding of TNF?, and low immunogenicity. Said antibodies are designed for the diagnosis and/or treatment of TNF?-related disorders. The nucleic acids, vectors and host cells for expression of the recombinant antibodies of the invention, methods for isolating them and the use of said antibodies in medicine are also disclosed.

  • Patent number: 8936785
    Abstract: scFv antibodies which specifically bind selected antigens and are obtainable by a method comprising (i) selecting from a pool of soluble and stable antibody frameworks a soluble and stable framework matching best the framework of a non-human antibody against the antigen with a certain binding specificity, (ii) either providing said soluble and stable framework with CDRs that bind specifically to said antigen, or mutating the framework of said non-human antibody towards the sequence of said soluble and stable framework, to generate scFv antibodies, (iii) testing the generated antibody for solubility and stability, and testing the generated antibody for antigen binding, and (iv) selecting an scFV that is soluble, stable and binds to the antigen specifically. Also provided are pharmaceutical compositions comprising said scFv antibody, methods of treatment and diagnosis for diseases related to over expression of antigens that are specifically bound by said antibody.
