Synthetic peptides based on a complementarity-determining region (CDR) of the heavy or light chain of a pathogenic anti-DNA monoclonal antibody that induces a systemic lupus erythematosus (SLE)-like disease in mice, and analogs, and salts and chemical derivatives thereof; dual peptides comprising two such peptides or analogs covalently linked to one another either directly or through a short linking chain; peptide polymers comprising a plurality of sequences of said peptide or analog thereof; and peptide polymers attached to a macromolecular carrier, are disclosed, and pharmaceutical compositions comprising them for the treatment of SLE in humans.

La présente invention décrit des peptides synthétiques basés sur une région déterminant la complémentarité (CDR) de la chaîne lourde ou légère d'un anticorps monoclonal anti-ADN pathogénique qui induit une maladie analogue au lupus érythémateux systémique (SLE) chez les souris, ainsi que des analogues, des sels et leurs dérivés chimiques; des peptides doubles formés de deux desdits peptides ou analogues liées entre eux de façon covalente soit directement soit par l'intermédiaire d'une chaîne de liaison courte; des polymères de peptide comportant une pluralité de séquences dudit peptide ou d'un analogue de celui-ci; des polymères de peptide attachés à un porteur macromoléculaire, ainsi que des compositions pharmaceutiques les contenant pour le traitement de SLE chez les humains sont également décrits.
