C12P 21/08

US Classification:

5303871, 5303881, 5303891, 4241591

Abstract:

The present invention provides liquid formulations of antibodies or fragments thereof that immunospecifically bind to a respiratory syncytial virus (RSV) antigen, which formulations exhibit stability, low to undetectable levels of aggregation, and very little to no loss of the biological activities of the antibodies or antibody fragments, even during long periods of storage. In particular, the present invention provides liquid formulations of antibodies or fragments thereof that immunospecifically bind to a RSV antigen, which formulations are substantially free of surfactant, inorganic salts, and/or other common excipients. Furthermore, the invention provides methods of preventing, treating or ameliorating one or more symptoms associated with RSV infection utilizing the liquid formulations of the present invention.

Assignee:

MedImmune, Inc. - Gaithersburg MD

International Classification:

C07K 16/00

US Classification:

530387100

Abstract:

The present invention provides formulations of proteins comprising a variant Fc region that improve the stability in part by reducing the propensisty of such molecules to rapidly aggregate. The invention provides both liquid and lyophilized formulations either of which can be utilized to generate a high protein concentration liquid suitable for administration to a subject. The invention further provides methods of utilizing the formulations of the present invention for therapeutic or prophylactic treatment of diseases and disorders or for diagnostic purposes.
