  • Publication number: 20110300135
    Abstract: The invention provides a method for reducing aggregation and inhibiting flocculation of a macromolecule, such as a protein, under physiological conditions, by the addition of 5% to 20% polyvinylpyrrolidone (PVP) with a molecular weight range of 2000 to 54,000 daltons. The invention further provides a method to minimize inflammation at the injection site during subcutaneous administration of a macromolecule. In further aspects, the invention provides pharmaceutical formulations for subcutaneous administration of a macromolecule, and methods of treating a CD20 positive cancer or an autoimmune disease, comprising administering a humanized anti-CD20 antibody in a pharmaceutical formulation of the invention. The invention further provides an in vitro dialysis method to evaluate the ability of an excipient to reduce aggregation of an antibody or other macromolecule under physiological conditions.

  • Publication number: 20110236391
    Abstract: The present invention relates to a method of ultra- and dialfiltrating an antibody solution containing at least one solute in addition to the antibody, which comprises diafiltrating the antibody solution with a solvent and bringing said mixture into contact with a semi-permeable membrane so as to allow the at least one solute present in the antibody solution and having a molecular weight lower than the molecular weight cut-off of the membrane to pass through the membrane, whilst retaining the antibody so that a modified antibody solution is obtained that only contains the antibody and the solvent.

  • Patent number: 7960516
    Abstract: The invention relates to solid forms of antibodies against the EGF receptor, in particular precipitates and crystals of monoclonal antibodies against the EGF receptor, particularly preferably of Mab C225 (cetuximab) and Mab h425 (EMD 72000), which result in biologically active antibody protein through dissolution or suspension in aqueous medium, obtainable by precipitation of the antibody and/or one of its variants and/or fragments dissolved or suspended in aqueous medium by means of a precipitation reagent. The invention furthermore relates to pharmaceutical preparations comprising at least one solid form of above-mentioned antibodies in precipitated non-crystalline, precipitated crystalline or in soluble or suspended form, and optionally excipients and/or adjuvants and/or further pharmaceutical active ingredients, and to a process for the preparation of solid forms of anti-EGFR antibodies according to the invention.

  • Publication number: 20110076273
    Abstract: The present invention relates to a highly concentrated, stable pharmaceutical formulation of a pharmaceutically active anti-CD20 antibody, such as e.g. Rituximab, Ocrelizumab, or HuMab<CD20>, or a mixture of such antibody molecules for subcutaneous injection. In particular, the present invention relates to formulations comprising, in addition to a suitable amount of the anti-CD20 antibody, an effective amount of at least one hyaluronidase enzyme as a combined formulation or for use in form of a co-formulation. The said formulations comprise additionally at least one buffering agent, such as e.g. a histidine buffer, a stabilizer or a mixture of two or more stabilizers (e.g. a saccharide, such as e.g. ?,?-trehalose dihydrate or sucrose, and optionally methionine as a second stabilizer), a nonionic surfactant and an effective amount of at least one hyaluronidase enzyme. Methods for preparing such formulations and their uses thereof are also provided.
