Benefits of technology

This patent describes a pharmaceutical composition that does not require a buffer and contains adalimumab, a salt, a polyol, and a polysorbate. The composition is suitable for injection and can be stored without any stability issues. The technical effect of this patent is the creation of a stable pharmaceutical composition that is suitable for subcutaneous injection.

Problems solved by technology

While buffers serve to maintain a desired pH of the formulation, finding the right buffer can be problematic according to this disclosure.

example 1

[0026]The effect of NaCl on the thermal stability of adalimumab was tested in a 7500 Real Time PCR thermocycler system from Applied Biosystems by a qPCR-based Thermofluor Assay using SYPRO Orange dye (Invitrogen, Cat. no. S6651) to assess the apparent melting temperature (Tm) of adalimumab protein. The amount of fluorescence, which correlates with the degree of denaturation or melting of the protein, was determined as a function of temperature for several adalimumab samples having different concentrations of NaCl. The procedures are set forth below.

[0027]Adalimumab protein was supplied frozen in a matrix that contained phosphate buffer. The material was defrosted and then buffer-exchanged with water for injection (about 6 volumes) and concentrated to 108 mg / ml using UF / DF apparatus. Samples for testing were then prepared with a final concentration of 0.2 mg / ml adalimumab protein, 1:2000 dilution of the supplied SYPRO orange dye stock, and the indicated concentration of NaCl: 0, 5, 2...

example 2

[0030]The effect of other salts on the thermal stability of adalimumab was tested in accordance with the procedures described in Example 1. The melting point as determined according to the above procedure are reported below in Table 3 for the salts MgCl2, KCl, and CaCl2, each at three different concentrations.

TABLE 3Tm lowTm highCondition(° C.)(° C.)No salt (WFI)N / A72.3 ± 0.15 mM MgCl2N / A71.1 ± 0.025 mM MgCl2N / A71.8 ± 0.1125 mM MgCl261.7 ± 0.269.9 ± 0.25 mM KClN / A71.6 ± 0.125 mM KClN / A71.9 ± 0.1125 mM KCl64.4 ± 0.270.1 ± 0.25 mM CaCl2N / A70.5 ± 1.125 mM CaCl266.9 ± 0.872.7 ± 0.8125 mM CaCl261.4 ± 0.170.8 ± 0.2

[0031]All three salts developed a second, lower melting point at a concentration of 125 mM. Thus, at such concentrations, the thermal stability of adalimumab becomes a concern. The salt CaCl2 developed a second melting point also in the 25 mM concentration, which renders it less preferred from a thermal stability perspective.

[0032]The following formulations in Table 4 were made and placed on stability as described below. Two formulations correspond to the present invention (Samples 1 and 2) and a Control Sample corresponds to the formulation used in the approved 100 mg / ml HUMIRA® composition.

[0034]The Samples were prepared as follows. Frozen adalimumab material was defrosted, concentrated, and buffer-exchanged with water for injection in like manner as described in Example 1 to obtain adalimumab in WFI in a concentration of 108 mg / ml. The adalimumab protein in water was then dialyzed against a 230 mM solution of Mannitol for Sample 2 and the Control sample and against 255 mM sucrose for Sample 1. Stock solutions of NaCl (4 M), and Polysorbate 80 (20% w / v) were added as...

Abstract

A pharmaceutical composition comprises a buffer-less aqueous formulation of adalimumab, a salt, a polyol, and a polysorbate. The formulation is suitable for injection.

Description

FIELD OF THE INVENTION[0001]The present invention relates to pharmaceutical formulations for delivering the anti-TNFα antibody known as adalimumab.BACKGROUND OF THE INVENTION[0002]Adalimumab is an IgG antibody that binds TNF-α (Tumor Necrosis Factor alpha). It was disclosed in U.S. Pat. No. 6,090,382 under its code name of D2E7, which remained a popular identifier. The current commercial adalimumab product is sold under the brand name HUMIRA® (AbbVie) as a parenteral formulation that is typically administered by subcutaneous injection. The parenteral formulations are sold in two concentrations of adalimumab: the original 50 mg / ml and the more recent high concentration of 100 mg / ml.[0003]The published patent application US 2006 / 0153846, which subsequently was granted as U.S. Pat. No. 8,216,583 to Abbott Biotechnology, Ltd (a predecessor to AbbVie), describes aqueous injectable formulations of adalimumab (D2E7). The formulations feature a buffer system comprising citrate and phosphate...
