The present invention provides a method for producing a concentrated antibody preparation that includes the steps of: (a) obtaining an initial antibody preparation that is an aqueous solution of antibodies and histidine or acetate buffer at a concentration in the range of from about 2 mM to about 48 mM; and (b) subjecting the antibody preparation to membrane filtration so as to remove water and buffer but not antibodies from the antibody preparation, thereby producing an antibody preparation having a higher concentration of antibodies than the initial antibody preparation. The concentrated antibody preparations produced by the method have lower viscosity and are more stable than those of other formulations. The invention further includes concentrated antibody preparations produced by the method, pharmaceutical compositions made using such preparations, and therapeutic methods in which such pharmaceutical compositions are administered to treat diseases.

La présente invention concerne un procédé pour produire une préparation d'anticorps concentrée. Ce procédé consiste (a) à obtenir une préparation d'anticorps initiale qui est une solution aqueuse d'anticorps et de tampon d'histidine ou d'acétate à une concentration située entre environ 2 mM et environ 48 mM, puis (b) à soumettre cette préparation d'anticorps à une filtration sur membrane, afin d'éliminer l'eau et le tampon, mais pas les anticorps, de la préparation d'anticorps, ce qui permet d'obtenir une préparation d'anticorps qui présente une concentration d'anticorps plus élevée que la préparation d'anticorps initiale. Les préparations d'anticorps produites selon ledit procédé présentent une viscosité inférieure et sont plus stables que les autres préparations. La présente invention concerne également des préparations d'anticorps concentrées produites selon ledit procédé, des compositions pharmaceutiques produites avec ces préparations, ainsi que des procédés thérapeutiques consistant à administrer ces compositions pharmaceutiques afin de traiter des maladies.
