This solution does not disclose the technological aspects of producing a drug based on a recombinant human C1-esterase inhibitor.
- WO 1992022320 discloses a method for the treatment of systemic inflammatory diseases in mammals, incl. preeclampsia, the introduction of a therapeutically effective amount of C1-INH or its variants, without disclosing aspects of the production technology.
- Application WO 2017/087882 A1 discloses a large number of aspects related to medical use, pharmaceutical composition and technology for the production of a human C 1 esterase inhibitor.
- This solution discloses the process of cultivating a producer strain both in perfusion mode and in a fed-batch mode in a bioreactor with a volume of 5 liters; 10 l; 200 l; 500 l; 500 l; 1000 l; 2000 l; 5000 l; 10000 l; 15,000 l or 20,000 l with the final productivity in the culture liquid at the level of 5, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160 , 170, 180, 190, 200, 210, 220, 230, 240, 250, 260, 270, 280, 290, or 300 mg per day (in perfusion mode).
- the application also indicates that one or more methods based on the use of affinity chromatography, gel filtration, anion exchange chromatography, cation exchange chromatography, multimodal chromatography, hydrophobic chromatography, as well as non-chromatographic methods (centrifugation, ethanol precipitation, etc.) .) With obtaining a preparation of a Cl-esterase inhibitor with a purity of at least 90% (the method for assessing the purity is not specified).
- the description indicates general approaches to the removal of contaminants: proteins of the producer strain, DNA, viruses using chromatographic methods with different principles of action.
- compositions containing, as an active ingredient, an inhibitor of human C 1 esterase and auxiliary substances from the following categories: salts, salts with buffering properties, alcohols, various sugars, amino acids, etc. These compositions can have different pH values, as well as different format: solution or lyophilisate.
- Application WO2017 / 087882 is the closest to the claimed invention, affecting the technological aspects of the production of a medicinal product.
- the purification method known from the application WO2017 / 087882 can include various chromatography steps routinely used in protein purification, such as affinity, ion-exchange, anion-exchange, cation-exchange, multimodal, hydrophobic chromatography on the POROS XS sorbent, as well as mandatory are the stages of viral inactivation and diafiltration.
- affinity affinity, ion-exchange, anion-exchange, cation-exchange, multimodal, hydrophobic chromatography on the POROS XS sorbent
- the authors of the application did not manage to achieve the final purity of the drug necessary for the drug: the HCP content after all stages of purification was about 1960 ng / mg. The yield of the monomeric form was about 90%.
- the residual DNA content after all stages of purification ranged from 5 to 13 pg / mg.
- the above chromatographic purification technology makes it possible to obtain a preparation with a low DNA content, however, during the production of a batch under GMP conditions, the obtained DNA level was 13 pg / mg, which almost corresponds to the declared upper border of the norm (14 pg / mg), and indicates the variability of the process with T.Z. removing DNA.
- the technical result to be achieved by the claimed invention is to develop a method for producing a highly purified recombinant human C 1-esterase inhibitor for medical use, with a high yield of biologically active monomeric form of the protein relative to the target protein content in the culture liquid.
- a highly efficient technology for producing an active pharmaceutical substance of a recombinant human C1-esterase inhibitor was developed, scaled up and transferred to production, which makes it possible to obtain a drug containing no more than 10 ng / mg of proteins of the producer strain; no more than 5 pg / mg DNA; not less than 99.0% of the monomeric form of the protein; not less than 99.5% of the basic form according to reverse-phase HPLC and specific activity not less than 9.0 IU / mg.
- the claimed production technology makes it possible to obtain an active pharmaceutical substance suitable for use in clinical trials and commercial release.
- the combination of the above conditions made it possible to obtain a protein solution with a protein content of the producer strain at the level of 5000 ng / mg; DNA at the level of 7000-8000 pg / mg; the content of the monomeric form of the protein at the level of 95.0%; while the protein yield from stage amounted to about 95% of its content in the culture fluid.
- Heparin Sepharose FF affinity sorbent can significantly reduce the content of proteins of the producer strain and DNA. It was found that at a pH value of 7.0 to 8.0 and a conductivity of 0.1 to 10.0 mS / cm (mS / cm) of the applied protein solution, as well as the elution of the target protein by increasing the sodium chloride content in the mobile phase to values 0.2 - 0.4 M, the protein content of the producer strain decreases to a level of about 3000 ng / mg, and the DNA content to a level of less than 50 pg / mg. Table 4 shows data for screening elution conditions on Heparin Sepharose FF.
- a purification stage was developed that allows one to significantly reduce the amount of proteins of the producer strain in the eluate of the target protein - to a level of less than 3000 ng / mg, while bringing the DNA content to a level of less than 50 pg / mg.
- the protein content of the producer strain is not more than 10 ng / mg
- DNA content of the producer strain is not more than 5 pg / mg; ⁇ Specific specific activity not less than 9.0 IU / mg.
- the yield of the target protein relative to its content in the culture fluid was about 80% (500 mg of the target protein from 1 liter of the culture fluid).
- Phenyl Sepharose FF, Tosoh Butyl 650M, Capto Phenyl, as well as other commercially available sorbents with a similar principle of action can be used as a suitable hydrophobic sorbent containing phenyl groups.
- the culture liquid with a volume of 1 L was applied to a column with an IMAC Sepharose sorbent (column volume (CV) 0.2 L), previously activated with 2 CV of 0.1 M zinc chloride solution and equilibrated with a buffer solution of 20 mM Tris, pH 7.2. After application, the sorbent was washed with 3 CV of the same buffer solution. The column was washed with 3 CV buffer solution of 20 mM Tris, 15 mM imidazole, pH 7.5. The target protein bound to the sorbent was eluted with a buffer solution of 20 mM Tris, 150 mM imidazole, pH 7.2. Viral inactivation was performed using a solvent-detergent method.
- the obtained protein fraction was diluted 2-fold with water and applied to a Heparin Sepharose (CV 0.1 L) column pre-equilibrated with 20 mM Tris buffer, pH 7.2.
