Problems solved by technology

Although the preparation has stability, it is still not enough to stabilize the antibody for a long time, and it is expected that the finished product should not be placed for a longer period of time
This may be due to the fact that the antioxidant and osmotic pressure regulator used in the preparation - mannitol can not play a good stabilizing effect
In addition, the surfactant used in the existing adalimumab is Tween-80, although it can inhibit and / or prevent undesirable results such as polymerization and adsorption of protein molecules at the interface between water and air and the contact surface of the inner packaging material, thereby stabilizing Antibodies, but to a certain extent, they also undergo unsaturated bond oxidation and ester bond hydrolysis to produce acids, aldehydes, and hydrogen peroxide, which affects the stability of antibodies
At the same time, the composition of its prescription buffer solution is redundant and complicated, which not only increases the product cost, but also makes the preparation operation of the preparation cumbersome

Abstract

The invention provides a new liquid aqueous drug preparation of an anti-TNF (tumor necrosis factor)-alpha human monoclonal antibody for strengthening the stability, wherein antibody solution is stabilized and osmotic pressure is regulated by sorbitol; disodium hydrogen phosphate / citric acid monohydrate or sodium acetate / acetic acid is taken as a buffer agent, and preferably, the disodium hydrogen phosphate / citric acid monohydrate is taken as the buffer agent; and tween-20 is taken as a surfactant, so that antibody preparation is stable, and long in retention time, meanwhile, preparation components are simplified, and the preparation is prepared simply and conveniently.

Description

technical field [0001] The invention belongs to the field of biotechnology, and relates to a liquid aqueous pharmaceutical preparation of a fully human monoclonal antibody drug with enhanced stability; it relates to the application of the liquid aqueous pharmaceutical preparation of the invention to treat related diseases. Background technique [0002] Human tumor necrosis factor alpha (TNF-α) has been confirmed to be associated with various diseases, such as autoimmune diseases such as rheumatoid arthritis and psoriasis. A number of anti-TNF-α drugs have been approved by the US FDA for the treatment of TNF-α-related autoimmune diseases, such as Adalimumab (Adalimumab, trade name Humira, Abbott). [0003] Adalimumab used in clinical treatment is a liquid injection preparation, and the inner packaging material is a prefilled syringe. Its preparation prescription contains sodium chloride, disodium hydrogen phosphate, sodium dihydrogen phosphate, citric acid, sodium citrate, m...
