Benefits of technology

[0006]The present invention is based, in part, on the development of high concentration liquid formulations of antibodies (including antibody fragments thereof) that immunospecifically bind to an IL-9 polypeptide, which formulations exhibit, in the absence of surfactants, sugars, sugar alcohols, and amino acids other than histidine (preferably, free of amino acids with pKa values of less than 5 and above 7), stability, low to undetectable levels of antibody fragmentation and / or aggregation, and very little to no loss of the biological activities of the antibodies (including antibody fragments thereof) during manufacture, preparation, transportation, and storage. The liquid formulations of the present invention facilitate the administration of antibodies (including antibody fragments thereof) that immunospecifically bind to an IL-9 polypeptide for the prevention, treatment, management and amelioration of diseases or disorders associated with or characterized by aberrant expression and / or activity of an IL-9 polypeptide, diseases or disorders associated with or characterized by aberrant expression and / or activity of the IL-9 receptor (“IL-9R”) or one or more subunits thereof, autoimmune diseases, inflammatory diseases, proliferative diseases, or infections (preferably, respiratory infections), or one or more symptoms thereof (e.g., wheezing). Examples of autoimmune diseases include, but are not limited to: diabetes, Hashimoto's disease, autoimmune adrenal insufficiency, pure red cell anemia, multiple sclerosis, rheumatoid carditis, systemic lupus erythematosus, rheumatoid arthritis, chronic inflammation, Sjogren's syndrome polymyositis, dermatomyositis and scleroderma. Examples of inflammatory disorders include, but are not limited to, asthma and allergic reactions (Types I-IV). Examples of respiratory infections include, but are not limited to, infections of the upper and lower respiratory tracts, including viral infections, bacterial infections and / or fungal infections. Examples of viral infections include parainfluenza virus infection, influenza virus infection, metapneumovirus infection, or respiratory syncytial virus (RSV) infection. The antibody formulations of the invention may also be used to treat subjects that have or previously had bronchopulmonary dysplasia, congenital heart disease, cysteic fibrosis or acquired or congenital immunodeficiency. In particular, the liquid formulations of the present invention enable a healthcare professional to quickly administer a sterile dosage of an antibody (including antibody fragment thereof) that immunospecifically binds to an IL-9 polypeptide without having to accurately and sterilely reconstitute the antibody (including antibody fragment thereof) prior to administration.

Problems solved by technology

Lyophilized formulations of antibodies have a number of limitations, including a prolonged process for lyophilization and resulting high cost for manufacturing.
Such reconstitution procedure is cumbersome and the time limitation after the reconstitution can cause a great inconvenience in administering the formulation to patients, leading to significant waste, if not reconstituted properly or if the reconstituted dose is not used within six (6) hours and must be discarded.
Prior liquid antibody preparations have short shelf lives and may lose biological activity of the antibodies resulting from chemical and physical instabilities during the storage.
Chemical instability may be caused by deamidation, racemization, hydrolysis, oxidation, beta elimination or disulfide exchange, and physical instability may be caused by antibody denaturation, aggregation, precipitation or adsorption.

Embodiment Construction

[0099]The liquid formulations of the present invention provide a ready-to-use preparation of an antibody (including antibody fragment thereof) that immunospecifically binds to an IL-9 polypeptide for administering to a subject without having to reconstitute the preparation accurate and aseptical techniques, and waiting for a period of time until the solution clarifies before administering the formulation to the subject. In addition, such reconstituted solutions must be used within a certain period, leading to very costly waste. It simplifies the procedure of administering the formulation to a subject for a healthcare professional. Furthermore, due to its high stability during the storage, the formulations of the present invention can contain an antibody (including antibody fragment thereof) that immunospecifically binds to an IL-9 polypeptide at concentrations in the range of about 15 mg / ml to about 300 mg / ml without causing an adverse effect on the biological activities of the anti...

Abstract

The present invention provides liquid formulations of antibodies or antibody fragments that immunospecifically bind to an IL-9 polypeptide, 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 an IL-9 polypeptide, which formulations are substantially free of surfactants, sugars, sugar alcohols, amino acids other than histidine (preferably with pKa values of less than 5 and above 7), and / or other common excipients. Furthermore, the invention provides methods of preventing, treating or ameliorating a disease or disorder associated with or characterized by aberrant expression and / or activity of an IL-9 polypeptide, a disease or disorder associated with or characterized by aberrant expression and / or activity of the IL-9R or one or more subunits thereof, an autoimmune disease, an inflammatory disease, a proliferative disease, or an infection (preferably, a respiratory infection), or one or more symptoms thereof, utilizing the liquid formulations of the present invention.
