  • Publication number: 20180221377
    Abstract: The present invention is directed to methods of treating movement disorders by administering an effective amount of one or more adenosine A2A receptor antagonists to a patient in need thereof. The present invention also provides methods of decreasing the adverse effects of L-DOPA in patients receiving L-DOPA therapy in the treatment of Parkinson's disease. The present invention further provides methods and compositions for treating Parkinson's disease patients with sub-clinically effective doses of L-DOPA by combining L-DOPA treatment with an effective amount of one or more adenosine A2A receptor antagonists (i.e., L-DOPA sparing effect). The present invention further provides methods of effective treatment of Parkinson's disease by co-administering at least one adenosine A2A receptor antagonist, L-DOPA and a dopamine agonist and/or a COMT inhibitor and/or a MAO inhibitor.

  • Patent number: 6872392
    Abstract: Chimeric human antibody expression vectors are constructed by inserting the heavy chain variable region-encoding cDNA and antibody light chain variable region-encoding cDNA isolated from hybridomas producing a mouse or rat monoclonal antibody reacting with the ganglioside GM2 respectively into an expression vector which contains the human antibody heavy chain constant region- or human antibody light chain constant region-encoding cDNA. The expression vectors are introduced into animal cells and the transformant thus obtained is cultured to produce a chimeric human antibody reacting with the ganglioside GM2. In contrast to mouse monoclonal antibodies, the chimeric human antibodies of the invention will not cause anti-mouse immunoglobulin antibody production in the patient's body but show a prolonged blood half-life, with a reduced frequency of adverse effects, so that it can be expected to be superior to mouse monoclonal antibodies in the efficacy in the treatment of human cancer, for instance.
