  • Method and agent for the therapy of immunocomplex diseases
    Patent number: 4479934
    Abstract: What is disclosed is a method for the therapy of immunocomplex diseases with an agent which contains Fc-reagents that react with the Fc-part of the antibody contained in the immunocomplex, but which themselves do not posses an immunologically active Fc-part or an Fc-part capable of being activated.
    Type: Grant
    Filed: December 10, 1979
    Date of Patent: October 30, 1984
