Abstract
The invention provides a preparation method of a pharmaceutical composition containing recombinant protein, which is specifically improved on the basis of a disposable filtration and filling system, and a peristaltic pump (6) for filling is added with a back-end filter (7). The invention solves the problem that the recombinant protein composition filled by the traditional stainless steel tube tank system or the disposable filtering and filling system has visible particles.
Description
The application is a divisional application, the application date of the original application is 2019, 11, 13, 201911104057.5, and the name of the application is "preparation of a pharmaceutical composition containing recombinant proteins".
Technical Field
The invention relates to the field of proteins, in particular to a preparation method and production equipment of a pharmaceutical composition containing recombinant proteins, and particularly relates to a preparation method and production equipment of a composition containing antibodies or clotting polypeptides.
Background
Protein instability includes chemical instability and physical instability. Chemical instability involves the formation or destruction of covalent bonds, creating new chemical entities. In contrast, physical instability refers to the fact that the chemical composition is not changed, but the physical state of the protein is changed, such as denaturation, aggregation, precipitation, adsorption, etc. Among them, protein aggregation has become one of the most well-defined subjects in the field of protein stability.
Blood clotting phenomena involve a cascade of coagulation factors, indicated by numbers from I to XIII, which participate in coagulation in the reverse order of their numbering, except for factors XIII, which participate in the last step of the clotting reaction, each factor being present in the form of an inactive precursor and in the activated form indicated by letter a. Blood coagulation involves two pathways: intrinsic and extrinsic pathways. Wherein the intrinsic pathway comprises factors present in the blood circulation and the clotting process starts from within the blood vessel. The extrinsic pathway involves coagulation factors that are not entirely present in the blood, but also tissue factors that are released in vascular lesions. The extrinsic pathway involves the intervention of factor vii (vii), activated factor viia being one of the factors involved in the hemagglutination mechanism, with a molecular weight of about 50 kDa. Fviia binds tissue factor and initiates subsequent activation of the coagulation factor, resulting in a coagulation cascade. Fviia can act locally even in the absence of factor viii or ix.
NovoSeven RT developed by Danenode and Norde is recombinant human factor VIIa, similar in structure to human plasma-derived factor VIIa. It has been approved for bleeding event and perioperative management in haemophilia a/B patients, congenital factor VII deficiency patients and platelet dysfunction patients, and for bleeding event and perioperative management in acquired haemophilia patients.
As a protein medicine, the FVIIa has poor stability in a solution state and is easy to generate physical and chemical changes under the action of external factors, thereby influencing the effectiveness and safety of the medicine. NovoSeven RT, developed and produced by Norand Norde, is a method of maintaining long-term stability of the product by lyophilization. However, during the production of the preparation, the interfacial stability of the contact between the tube and the feed liquid, the generation and breaking of bubbles, the shearing force during the transmission, and the like may cause aggregation of proteins, generate sub-visible and visible particles, and increase the possibility of adverse immunogenic reactions during the treatment.
IgG4 antibody drugs represented by the PD-1 inhibitor Nivolumab (Na Wu Liyou antibody) also have similar problems of protein aggregation stability during preparation production. This is probably because IgG4 antibodies are structurally distinct from other subtypes, resulting in faster aggregation rates under agitation and high temperature conditions and also in the formation of more sub-visible particles when contacted with stainless steel reservoirs, EVA-based reservoirs, etc.
The traditional workshop production, preparation and filtration adopts a stainless steel pipe tank system, stock solution is mixed in a stainless steel tank, the stock solution is pressurized by compressed air and is sterilized and filtered by a two-stage 0.22 mu m pore size filter and is pressed into a stainless steel liquid storage tank, and the tank bodies are connected by using a stainless steel pipe. The sterilized and filtered feed liquid is stored in a stainless steel tank, compressed air is adopted to convey the feed liquid to a stainless steel buffer tank in a pressurizing mode, and then peristaltic pump is used for filling. With this system, metal ions in the stainless steel tube can catalyze protein oxidation, making the protein unstable; the solid-liquid interface effect of the feed liquid contacted with the tube tank can also cause unstable protein and aggregation; the use of compressed air for pressurization can lead to a large amount of generation of bubbles, the generation and the breaking of the bubbles can lead to the great increase of gas-liquid interfaces, and the action of the gas-liquid interfaces can also damage the protein structure to cause protein aggregation. When the traditional technology is used for production, once the protein in the filtered feed liquid is aggregated to generate sub-visible and visible particles, the sub-visible and visible particles are packaged in penicillin bottles and then are freeze-dried, so that the particles in the freeze-dried finished preparation product can be increased. The microparticles are injected into the human body, may generate an immunogenic reaction, even block blood vessels, and may be harmful to the user.
At present, a disposable filtering and filling system is increasingly used in the production of biological medicines, a liquid storage bag made of high-molecular polymer materials is used for replacing a stainless steel tank, a silica gel hose is used for replacing a stainless steel pipeline, and a peristaltic pump is used for conveying feed liquid to replace compressed air. Compared with the traditional technology, the technology reduces the risk of stainless steel influence and reduces the generation of bubbles. However, for some proteins with poor stability and greater influence of hydrophobic forces (e.g. fviia, igG4 antibodies), aggregation may still occur when the proteins are contacted with a liquid storage bag with a hydrophobic inner surface, and such a liquid may be directly filled into a penicillin bottle for lyophilization, which may result in a large number of visible particles in the finished product.
The research shows that the raw liquid of the FVIIa and the IgG4 antibody has few particles after being subjected to sterilization and filtration, meets the Chinese pharmacopoeia standard, but the particles of the feed liquid are obviously increased after the raw liquid passes through a stainless steel liquid storage tube (or liquid storage bag) and is filled into a penicillin bottle. There is an urgent need for a new preparation production device and process that can reduce the particle content of proteins with poor stability such as fviia and IgG4 antibodies after filling, and improve the quality and safety thereof.
In the production of recombinant protein preparation, peristaltic pump for filling is directly connected with filling needle. We have tried to add a filter between the reservoir bag (4) and the dispenser (5) or between the dispenser (5) and the peristaltic pump (6) for filling to achieve re-filtration before filling, however neither of the above improvements fundamentally solves the visible particulate problem of the product after filling.
