Description

Antibody-containing liquid formulation

The present invention relates to an antibody-containing liquid preparation.

Recombinant monoclonal antibodies such as tocilizumab are currently used as active ingredients in pharmaceuticals. In general, antibody pharmaceutical preparations often have a higher protein concentration than other biopharmaceutical preparations, and attention must be paid to aggregate formation. In addition, in order to obtain a sufficient therapeutic effect, the dose of the recombinant monoclonal antibody per administration may be large. For example, when a preparation for subcutaneous injection capable of self-injection is used, one injection There is a limit to the amount of liquid. Therefore, it may be necessary to increase the concentration of the recombinant monoclonal antibody contained in the preparation.

In general, injections are known for various administration routes such as subcutaneous administration and intravenous administration, and any preparation is generally used because it is required to be a liquid preparation for convenience of immediate use. In many cases, simply dissolving a lyophilized drug formulation has not been able to satisfy long-term practical stability as a pharmaceutical product.

Until now, as a liquid preparation containing high-concentration recombinant monoclonal antibody, a pharmaceutical formulation containing a specific amount of arginine, methionine, polysorbate (Patent Document 1), or a pharmaceutical formulation containing a specific amount of arginine hydrochloride, histidine, polysorbate ( Patent Document 2) and the like are known.
In these pharmaceutical formulations, when the content of the recombinant monoclonal antibody is 150 mg / mL or more, the content of amino acid components such as arginine is 100 mM or more.

If the activity of the antibody is not impaired, a stored (for example, refrigerated) antibody drug substance can be used. Alternatively, it is an antibody drug substance in which recombinant monoclonal antibodies are produced in cells transformed by applying recombinant DNA technology, purified, and frozen. Alternatively, it is a commercially available frozen antibody drug substance.
Step A is a step of preparing an antibody including any one of Step A-1 to Step A-3. Step A-1 is a step of thawing the antibody drug substance that has been cryopreserved into a liquid state. Frozen antibody drug substance can be thawed into a liquid state by any method that does not impair the activity of the antibody. For example, melting at room temperature, melting by refrigeration, and the like can be mentioned. The antibody drug substance may be frozen with any solvent. The aqueous solution for production of the recombinant monoclonal antibody-containing liquid preparation of the present invention is preferable, but water, physiological saline, glucose solution, any buffer solution, ethanol solution, and other pharmaceutically usable solvents may be used. The melted antibody drug substance can be dialyzed and solvent exchanged using any solvent. Step A-2 is a step of preparing a liquid antibody drug substance containing an arbitrary solvent. Liquid antibody drug substances can be dialyzed and solvent exchanged using any solvent. Step A-3 is a step of preparing a powdery antibody drug substance.
Step B is a step of preparing an additive solution containing an amino acid. For example, an amino acid can be added to a solvent (for example, water, physiological saline, dextrose solution, arbitrary buffer solution, ethanol solution, and other pharmaceutically usable solvents) to form an additive solution.
Process C is a step of mixing the drug substance melted in Process A with the additive solution prepared in Process B. The final concentration of the amino acid component in the whole liquid is adjusted, for example, to 45 mM to 94 mM where the histidine component is less than 5 mM.

Step E is a step of filter sterilizing the solution prepared in Step C or Step D. For filtration sterilization, for example, a cartridge filter made of polyvinylidene fluoride can be used. Alternatively, other generally used sterilization methods may be used.
Step F is a step in which the solution prepared in Step C, Step D or Step E is filled and plugged. Alternatively, it may be filled in an ampoule or prefilled syringe, or a premixed bag.

When subcutaneous injection is performed, the dose of recombinant monoclonal antibody per administration is as large as 150 mg / mL to 200 mg / mL, but the amount of injection solution is limited. The liquid preparation in the present invention contains 150 mg / mL to 200 mg / mL recombinant monoclonal antibody and exhibits a kinematic viscosity that enables subcutaneous injection. Therefore, the liquid preparation containing 150 mg / mL to 200 mg / mL recombinant monoclonal antibody in the present invention is preferably used for subcutaneous injection from the viewpoint that the effects of the present invention can be obtained. Subcutaneous injection is not only performed by doctors and other specialists as medical professionals, but may be self-injected by the patient himself, and depending on ethnicity and region, many patients are worried about self-injection, It is preferable that the kinematic viscosity is low and the stability over time is excellent. In the present invention, the liquid preparation containing 10 to 30 mg / mL recombinant monoclonal antibody is preferably used as an intravenous preparation. In addition, it is highly industrially convenient that a preparation for subcutaneous injection and a preparation for intravenous injection having different concentrations can be prepared in a solution having the same composition during the production of these preparations.

The kinematic viscosity may be measured with an Ubbelohde viscometer (16th revision Japanese Pharmacopoeia General Test Method 2.53 Viscosity Measurement Method Method 1). Alternatively, the tension generated in the pusher when the evaluation sample solution is sucked with the injection needle attached to the glass syringe is measured, and the obtained tension is used for viscometer calibration with a kinematic viscosity of 2 mm2 / s to 20 mm2 / s. The kinematic viscosity may be obtained by applying a standard solution (Japanese grease) to a calibration curve created from the tension and kinematic viscosity obtained by measuring in the same manner.
The dimer product and the low molecular weight decomposition product can be measured by size exclusion chromatography using, for example, a high performance liquid chromatograph system (Prominence, manufactured by Shimadzu Corporation).
Biological activity can be assessed by measuring the binding effect to the antigen. For example, with tocilizumab, the inhibitory action of IL-6 binding to soluble IL-6 receptor by tocilizumab can be measured using an ELISA method. Alternatively, the biological activity measurement evaluates an effect of an antigen and an influence on suppression or promotion of an in vivo reaction via the antigen. For example, with tocilizumab, the effect of tocilizumab on the expression of IL-6 activity via membrane-bound IL-6 receptor can be evaluated from the IL-6-dependent cell growth inhibitory action.
The deamidated substance can be measured by ion exchange chromatography using, for example, a high performance liquid chromatograph system (Prominence, manufactured by Shimadzu Corporation).

The present invention will be described in further detail with reference to the following examples, but the present invention should not be construed as being limited to these examples. In this specification, the indication of% is mass% unless otherwise specified.
