Abstract
Description
Liquid Formulations Comprising High Concentrations Humanized Antibodies for Treating IL-6 Related DiseasesFIELD OF THE INVENTION
[0001] Disclosed herein are liquid formulations comprising high concentrations humanized antibodies for treating an IL-6-related disease. The antibody formulation provides good antibody stability, acceptable viscosity and osmolarity for subcutaneous injection, and prevents aggregation, degradation of the monoclonal antibody, and acidic isomer increase. The formulation is applicable in stabilizing the structure and function of the humanized antibody.BACKGROUND
[0002] Humanized anti-interleukin 6 receptor antibodies are useful for the treatment of rheumatoid arthritis (RA) [Josef S Smolen, et al. EULAR recommendations for the management of rheumatoid arthritis with synthetic and biological disease-modifying antirheumatic drugs: 2013 update, Ann Rheum Dis, 2014; 73 (3) : 492-509] by binding to soluble and membrane-bound IL-6 receptors (sIL-6R and mIL-6R) and inhibiting sIL-6R and mIL-6R mediated signaling.
[0003] Pharmaceutical antibodies are typically administered by injection. Subcutaneous injections allow faster administration as compared with intravenous injections. However, for antibodies that require a high dosage (e.g., over 100 mg per dose) , the antibody concentration in a subcutaneous formulation needs to be high due to the limited volume that can be administered by each subcutaneous injection, which presents formulation challenges. For example, due to high concentration, antibodies tend to aggregate which leads to reduced stability and shorter self-life. High concentration also increases the viscosity of the formulation which can make manufacturing and injection through a needle difficult. To increase shelf-life, formulations can be prepared as powders by the lyophilization. However, lyophilized powder requires reconstitution in water, making administration more complicated. Therefore, there is a need for high concentration antibody liquid formulations having long term stability and suitable for subcutaneous injection that do not require reconstitution.SUMMARY

[0292] As used herein, the term “comprising” is intended to mean that the compositions or methods, etc., include the recited elements, but do not exclude others. “Consisting essentially of” when used to define compositions or methods, shall mean excluding other elements of any essential significance to the combination for the intended use, but not excluding elements that do not materially affect the characteristic (s) of the compositions or methods. “Consisting of” shall mean excluding elements not specifically recited. Embodiments defined by each of these transition terms are within the scope of this invention.
[0293] Terms as “stability” and “stable” used herein refer to the situation that in a liquid formulation comprising an antibody, the antibody does not, or only rarely, aggregate, degrade, or fragment under given production, formulation, transportation, and / or storage conditions. “Stable” formulations maintain biological activity under given production, formulation, transportation and / or storage conditions. The stability of the antibody, can be assessed by measuring the degree of aggregation, degradation or fragmentation and the like of the formulation by techniques such as SEC-HPLC, IEC-HPLC, CE-SDS, etc. In some embodiments, the main antibody peak in a stable formulation does not decrease more than 5 %after storing at room temperature for at least 3 months.
[0294] It should be noted that in the present invention, where a buffer or buffer system is included in a formulation, it is also meant that the buffer is included in the formulation and the buffer system is formed in the formulation by the buffer. A buffer is typically a combination of a weak acid or a weak base and its salt. For example, a histidine buffer (also called a histidine salt buffer) is typically formed by histidine and one or more of its salts, such as histidine hydrochloride, an acetate buffer is typically formed by acetic acid and one or more of its salts, such as sodium acetate. Unless otherwise specified, regardless of whether the buffer is in the form of acid / base and / or salt, the molar concentration of the buffer includes both the free acid / base and the salts.
[0295] In some embodiments, the concentration of monoclonal antibody in the antibody formulation is between about 120 and about 300 mg / mL. In some embodiments, the concentration of monoclonal antibody in the antibody formulation is about 130 to about 280 mg / mL. In some embodiments, the concentration of monoclonal antibody in the antibody formulation is about 140 to about 250 mg / mL. In some embodiments, the concentration of monoclonal antibody in the antibody formulation is about 160 to about 200 mg / mL. In some embodiments, the concentration of monoclonal antibody in the antibody formulation is about 170 to about 190 mg / mL. In some embodiments, the concentration of monoclonal antibody in the antibody formulation is about 180 mg / mL.

[0581] Formulation Preparation
[0582] The formulations shown in Table 4 were prepared according to known methods. Briefly a high concentration antibody solution having a desired buffer can be prepared by buffer exchange into the desired buffer followed by concentration through tangential filtration. The desired excipients are added to the high concentration antibody solution. If needed, the resulting solution can be diluted using the appropriate buffer to the final formulation having the desired antibody concentration. The formulation is filtered using 0.22 μm filters and filled into a container (e.g. Eppendorf tubes or 1 ml PFS) .

The chromatographic column was TSK-GEL G3000SWXL 7.8×300 mM, 5 μm (TOSOH) . The mobile phase was 200 mM K3PO4 with 250 mM KCl (pH 7.0) . UV detection wavelength was set at 280nm, the column temperature was 30 ℃, the loading quantity of sample was 40 μL (200 μg protein) , and the flow was kept for 35 minutes at a rate of 0.5mL / min. Chromatography was recorded and after integration, the percentage of monomer and aggregate in the sample solution was calculated by area normalization method.
[0589] IEC-HPLC analysis method:
[0590] A sample of a formulation being tested was diluted with water to an antibody concentration of 5mg / mL and tested by IEC-HPLC. Chromatographic conditions: column, TSK-GEL CM- 4.6×100 mM, 7 μm (TOSOH) ; mobile phase, mobile phase A (20 mM ACES, pH 8.0) and mobile phase B (20 mM ACES+200 mM NaCl, pH 8.0) ; the loading quantity of sample was 50 μg; UV detection wavelength was 280 nm; gradient elution was performed according to the elution gradient given below for 45 minutes. Chromatography was recorded. And after integration, the percentage of the main peak, the acidic region and the basic region was respectively calculated using a peak area normalization method. (Chromatography was manually integrated, a base line was drawn at a place where the base line was relatively flat, the integration starting time and the integration ending time were about 8 minutes before and after the retention time of the main peak, vertical lines were drawn at two peak valleys around the main peak, the acidic region was before the main peak that was followed by the basic region (the main peak was followed by basic peak 1, basic peak 2 and basic peak 3 in sequence) , and a vertical line was drawn at each peak valley of the basic region. )
[0591] Elution Gradients
[0592] Viscosity Determination:
[0593] Samples were returned to 25℃ normal temperature, and then measured it with a viscometer (Brookfield, DV2T) . About 1.2 to about 1.5mL of the sample were slowly injected into the cone (to avoid bubbles) , spread evenly, and then tested on the viscometer at a temperature of 25±2℃. The torque was between 40%-70%, and the rotation is about 7 to about 9 times for data recording.
[0594] Turbidity Determination:
[0595] Samples were returned to room temperature and an ultraviolet spectrophotometer (Eppendorf, BioPhotometer plus) was used for detection. The UV spectrophotometer was adjusted to 340nm, calibrated with water, and sample detection was performed only when the calibration result was 0.The disposable cuvette was rinsed with 300μl sample during the test, and then the 300μl sample was slowly poured into the disposable cuvette to avoid air bubbles during the process, and the cuvette was put into the UV spectrophotometer for data recording.
