  • Method for preparing dual virally inactivated immune globulin for intravenous administration
    Patent number: 6504012
    Abstract: A process for producing an intravenously-administrable gamma globulin solution substantially free of contaminating viruses by fractionating an impure gamma globulin solution and then treating the purified gamma globulin, in any order, with a solvent-detergent for viral inactivation and a heat treating for viral inactivation. Thereafter, denatured impurities, residual solvent and aggregate generated by the heat treatment are removed from the gamma globulin.
    Type: Grant
    Filed: May 22, 2001
    Date of Patent: January 7, 2003
    Assignee: Alpha Therapeutic Corporation
    Inventors: Raja R. Mamidi, Andranik Bagdasarian, Gorgonio Canaveral, Kazuo Takechi

  • Manufacturing method for intraveneously administrable immune globulin and resultant product
    Patent number: 6162904
    Abstract: A process for producing an intravenously-administrable gamma globulin solution substantially free of contaminating viruses by heat treating for viral inactivation and fractionating an impure gamma globulin solution and then treating the purified gamma globulin with a solvent-detergent for further viral inactivation. In a continuous process disclosed herein, partially purified gamma globulin solids is not recovered as an intermediate product during the disclosed process. In the continuous process, the fractionation to obtain a purified gamma globulin solution is carried out without precipitation of the desired gamma globulin.
