Summary for Patent: 9,963,516

Title:	Stable compositions of high-concentration allotype-selected antibodies for small-volume administration
Abstract:	Disclosed are methods, compositions and uses of high concentration antibody or immunoglobulin formulations for subcutaneous, intramuscular, transdermal or other local (regional) administration, in a volume of than 3, less than 2 or less than 1 ml. Preferably, the formulation contains a high concentration formulation (HCF) buffer comprising phosphate, citrate, polysorbate 80 and mannitol at a pH of about 5.2. The formulation more preferably comprises at least 100, 150, 200, 250 mg/ml or 300 mg/ml of antibody. The methods for preparing the high concentration formulation include ultrafiltration and diafiltration to concentrate the antibody and exchange the medium for HCF buffer. Other embodiments concern use of non-G1m1 (nG1m1) allotype antibodies, such as G1m3 and/or a nG1m1,2 antibodies. The nG1m1 antibodies show decreased immunogenicity compared to G1m1 antibodies.
