Title: Stable, low-viscosity antibody formulations and uses thereof

Description:
TECHNICAL FIELD 
     The present invention relates generally to antibody formulations. Specifically, the present invention relates to monoclonal antibody formulations with improved stability and low viscosity. 
     BACKGROUND 
     Antibody formulations can lose their efficacy over time due, for example, to the effects of denaturation, oxidation, aggregation, or other degradation reactions. Degradation and aggregation of antibodies in an antibody formulation can also pose risks such as toxicity or immunogenicity. High solution viscosity can negatively impact the manufacturability and performance of protein therapeutic agents, especially those formulated at high protein concentrations. 
     The low level of stability exhibited by currently available pharmaceutical antibody formulations is disadvantageous due to, for example, loss of efficacy of the antibody formulation before administration and possible toxicity and immunogenicity due to the degradation/aggregation. Traditional excipients used to stabilize proteins in solution can often increase the viscosity of the solution. Therefore, there is a need in the art for an antibody formulation that will allow for improved stability of antibodies. Additionally, there is a need in the art of antibody formulation that will allow for the development of stable and low-viscosity antibody solutions. 
     SUMMARY 
     The present invention is based on the discovery that antibodies can be stabilized in solution by including a salt selected from the group of magnesium glutamate, magnesium acetate, magnesium aspartate, magnesium sulfate, arginine acetate, arginine aspartate, arginine glutamate, arginine sulfate, lysine acetate, lysine aspartate, lysine glutamate, lysine sulfate, sodium acetate, sodium aspartate, sodium glutamate, sodium sulfate, lithium acetate, lithium aspartate, lithium glutamate, and lithium sulfate. The resulting stabilized antibody solutions are also less viscous compared to formulations which do not include one of these salts or that contain traditional excipients, for example sugars like sucrose, used to stabilize proteins. The osmolality of stabilized antibody solutions with one of these salts is also less than that with sugars and polyols such as sucrose, trehalose, sorbitol, mannitol etc. when formulated at equipotent concentrations. 
     In view of this discovery, provided herein are aqueous antibody formulations that include about 0.1 mg/mL to about 500 mg/mL of an antibody or an antigen-binding fragment thereof (e.g., any of the exemplary antibodies or antigen-binding fragments described herein or known in the art); about 1 mM to about 100 mM of a buffer (e.g., any of the exemplary buffers described herein or known in the art); and about 1 mM to 750 mM of a salt selected from the group consisting of: magnesium glutamate, magnesium acetate, magnesium aspartate, magnesium sulfate, arginine acetate, arginine aspartate, arginine glutamate, arginine sulfate, lysine acetate, lysine aspartate, lysine glutamate, lysine sulfate, sodium acetate, sodium aspartate, sodium glutamate, sodium sulfate, lithium acetate, lithium aspartate, lithium glutamate, and lithium sulfate, where the formulations have a pH of about 4 to about 8.

     DETAILED DESCRIPTION 
     Over the past few decades, therapies involving the use of monoclonal antibodies and other Fc-derived antigen-binding proteins have become a mainstay of modern medicine. There is an ever-increasing reliance on these complex molecules in various therapeutic areas including but not limited to oncology, immunology, immuno-oncology, cardiology with nearly 100 molecules approved for therapeutic use to date and more than 500 at various stages of development or clinical trials. 
     A fundamental aspect for ensuring the transition of these therapeutic entities from the lab into manufacturable and marketable products of high and consistent quality is their stability in the dosage form. Owing to their complex chemistry and structure, proteins are susceptible to various forms of physical and chemical degradation that can compromise the biological efficacy and safety of the final drug product. Protein aggregation for example is a key quality attribute that is routinely monitored for protein-based products and is critical to the determination of product shelf life. At a fundamental level, protein aggregation is linked to the stability of the native form of the protein, with a growth in non-native cell (e.g., a non-native mammalian cell) generally linked to an increased rate and extent of aggregation. Thus, it is no surprise that attempts to control and minimize aggregation during product shelf life (kinetic stability) are often mediated through the use of excipients or formulation conditions intended to increase conformational stability of the protein. Essentially, the intent is to stabilize the protein in its native conformation in order to minimize the population of aggregation-competent “non-native” species. Sugars and polyols, such as sucrose, trehalose, mannitol, sorbitol etc. are often used to stabilize proteins in their native state and reduce rates of aggregation. However an unwanted effect of using these stabilizers is the concentration-dependent increase in solution viscosity. 
     Solution viscosity is a key attribute of protein products especially those that are formulated at high protein concentrations (for example ≥100 mg/mL for an antibody or Fc-derived proteins of similar molecular weight) and it can critically impact the utility and success of the product. The manufacturability of a product and the end use by the patient or healthcare practitioner is intimately linked to the ability of a solution to flow seamlessly. High viscosity, for example, can necessitate the use of specialized administration devices or protocols which may not always be suitable for the desired population thereby limiting the use of the product. In other instances, high solution viscosity may require the application of manufacturing technologies which may negatively impact the stability of the protein (for example high-temperature processing). It is thus not unusual to employ viscosity-reducing excipients, such as salts and amino acids, in high protein concentration solutions. However, these excipients can negatively impact the stability of the protein thereby resulting in solutions with an increased aggregation rate compared to high-viscosity control solutions lacking the viscosity-reducing agent. In essence, commonly employed stabilizers and the viscosity-reducing excipients can have an opposite effect on product performance thereby complicating its development. 
     Another critical attribute for injectable products (most protein-based products) that needs to be considered is its osmolality. While intravenous solutions generally need to be isotonic, it is not unusual for subcutaneous solutions to be hypertonic. In fact, there is evidence in literature of hypertonic formulations resulting in enhanced protein bioavailability following subcutaneous administration (Fathallah, A. M. et al, Biopharm Drug Dispos. 2015 March; 36(2):115-25). Thus, the impact of solution osmolality (and thus tonicity) on injection site discomfort and/or reaction as well as bioavailability in the patient population needs to be carefully monitored and characterized during clinical development phases. 
     Thus, there is a need in the art of formulating antibody and other Fc-derived products for developing stable, low-viscosity solution formulations with well characterized osmotic properties.

A “stable” formulation is one in which a protein of interest (e.g., an antibody or an antigen-binding antibody fragment) therein essentially retains its physical stability and/or chemical stability and/or biological activity upon storage at about 4° C. to about 25° C. Various analytical techniques for measuring protein stability are known in the art. See, e.g., Peptide and Protein Drug Delivery, 247-301, Vincent Lee Ed., Marcel Dekker, Inc., New York, N.Y., Pubs. (1991) and Jones, A. Adv. Drug Delivery Rev. 10: 29-90 (1993). Additional methods for determining the stability of a protein (e.g., an antibody or antigen-binding antibody fragment) in a formulation are described in the Examples section. In some examples, the stability of a protein (e.g., an antibody or an antigen-binding antibody fragment) is determined according to the percentage of monomer protein in the solution, with a low percentage of degraded (e.g., fragmented) and/or aggregated protein. For example, an aqueous formulation comprising a stable protein may include at least 95% monomer protein. Alternatively, an aqueous formulation of the invention may include no more than 5% (e.g., no more than 4.5%, no more than 4.0%, no more than 3.5%, no more than 3.0%, no more than 2.5%, no more than 2.0%, no more than 1.5%, no more than 1.0%, or no more than 0.5%) aggregates and/or degraded protein. 
     In some embodiments of any of the aqueous antibody formulations described herein, the formulation has improved stability as compared to a control antibody or antigen-binding antibody fragment (e.g., as compared a control antibody formulation that includes all of the same components, except it does not include any of the following salts: magnesium glutamate, magnesium acetate, magnesium aspartate, magnesium sulfate, arginine acetate, arginine aspartate, arginine glutamate, arginine sulfate, lysine acetate, lysine aspartate, lysine glutamate, lysine sulfate, sodium acetate, sodium aspartate, sodium glutamate, sodium sulfate, lithium acetate, lithium aspartate, lithium glutamate, and lithium sulfate). 
     In some embodiments of any of the aqueous antibody formulations described herein, the formulation is stable (e.g., % HMW by SEC ≤5%) at 25° C. for 1 hour to about 2 years. In some embodiments of any of the aqueous antibody formulations described herein, the formulation is stable (e.g., % HMW by SEC ≤5%) at 25° C. for about 1 hour to about 2 years (e.g., about 1 hour to

Thermal (Conformational) Stability by Differential Scanning calorimetry (DSC)
 
     Thermal (conformational) stability was assessed by measuring the lowest unfolding temperature, T m1 , of mAbs on a capillary DSC system (Malvern). The impact of both the identity and concentration of different excipients on increasing the T m1  value was used to rank order their effectiveness at improving conformational stability. Measurements were conducted by ramping the temperature of the solution from 15° C. to 110° C. at a rate of 1° C./min. The temperature value at the maximum of the first peak was designated as T m1 . 
     Kinetic Stability by Size Exclusion Chromatography (SEC) 
     Kinetic stability was assessed by periodically measuring the amount of aggregates generated in mAb formulations stored at 40° C. for 4 weeks. SEC was used to quantify the levels of both aggregated and non-aggregated mAb molecules after 0, 1, 2, and 4 weeks of storage. Samples were measured by eluting 50 μg of total mAb off of a TSKgel UP-SW3000 column (Tosoh Co.) at a rate 0.43 mL/min with 40 mM Phosphate and 150 mM Sodium Chloride at pH 7.2 (detection wavelength: 280 nm). Aggregates were designated as high molecular weight species (HMWS) that eluted faster than non-aggregated mAb monomers; HMWS % was calculated by dividing the amount of aggregate generated by the sum of total aggregated+non-aggregated mAb molecules. The initial aggregation rate, k agg , was taken as the slope of a plot of HMWS % vs. storage time. 
     Viscosity Measurements of mAb Formulations 
     The viscosities of 150 mg/mL mAb formulations were measured on an initium rheometer (Rheosense). MAb formulations were forced through a microchannel at a single shear rate and pressure was measured at 20° C. 
     Example 1: Stabilization of an Fc-Mutant mAb 
     An Fc engineered mAb (antibody A) with a relatively low CH2 domain unfolding temperature (T m1 ), compared to traditional mAbs, was selected. Solutions of the mAb were prepared at 1 mg/mL in 10 or 20 mM histidine buffer at pH 5.5. The excipient solutions were prepared at 20 mM and 200 mM. Thermodynamic/conformational stability was evaluated by differential scanning calorimetry (DSC). Further, solutions of the mAb were prepared at 25 or 150 mg/mL concentration in the same buffer-excipient-pH solutions and kinetic or storage stability, as measured by rates of aggregation (k agg ), was evaluated at 5° C., 25° C. and 40° C. Excipients were then assessed based on their effectiveness in increasing T m1  (ΔT m1 ) and/or decreasing k agg  for antibody A in solution. Based on the identity of the salt used, T m1  could be increased by as much as 7° C. with magnesium salts generally resulting in the most effect ( FIG. 1 ). Arginine salts generally resulted in the least but still significant increase for antibody A. Of the anions, aspartates and glutamates were generally most effective in increasing the T m1 . For k agg  (40° C., 150 mg/mL antibody A), a general decrease was observed with increasing ΔT m1  ( FIG. 2 ). Based on the identity of the salt, a roughly 35× decrease in the aggregation rate was noted compared to the control formulation. Magnesium salts generally resulted in the most decrease in k agg  followed by arginine, lysine, lithium and sodium. 
     Example 2: Stabilization of Other Fc-Mutant mAb 
     Based on the results of Example 1, a subset of excipients was selected and their effectiveness as stabilizers was evaluated using another Fc-engineered mAb, with a relatively low T m1  (antibody B). 
     Solutions of antibody B (1 mg/mL) in 10 mM histidine buffer at pH 5.5 and 6.2 were prepared for conformational stability measurements. Solutions of antibody B (50 mg/mL) were prepared in the same buffer-excipient at pH 6.2 for kinetic stability (40° C.) analysis. Similar to the effect observed for antibody A, an increase in T m1  was observed for antibody B in a salt-dependent manner ( FIG. 3 ). Magnesium salts generally exhibited the most increase. For anions, glutamates were observed to be most effective in increasing T m1  followed by aspartates and sulfates. Consistent with the effect on T m1 , a decrease in k agg  was also noted in the presence of salts ( FIG. 4 ). Magnesium salts generally were most effective in increasing k agg . 
     Example 3: Stabilization of an Fc-Mutant mAb (Antibody A) as a Function of Excipient Concentration 
     Excipients were evaluated at higher concentrations, 500 mM and 750 mM, for their stabilizing effect on antibody A in solution. All excipients were shown to improve the conformational stability of antibody A by increasing T m1  to in a concentration dependent manner ( FIG. 5 ). Magnesium salts generally exhibited the most increase in T m1 ; ˜15° C. at 750 mM for magnesium glutamate. Furthermore, results from kinetic stability study ( FIG. 6 ) showed that these same excipients at 500 mM further decreased aggregation and k agg  compared to 200 mM concentration used in Example 1. 
     Example 4: Stabilization of a Wild-Type mAb 
     The same excipients as those used in Example 2 were also evaluated for their stabilizing effect on a traditional mAb (antibody C), which has a much higher T m1  than the Fc-mutants used in our studies. Most excipients moderately improved the conformational stability with increasing concentration (200 mM, 500 mM, and 750 mM) with the exception of sulfates ( FIG. 7 ). Aspartate and glutamate salts were generally better in stabilizing wild-type antibodies. 
     Example 5: Stabilization of Another Wild-Type mAb and its Single and Double Amino Acid Mutants 
     Aspartic and glutamic acid salts of magnesium, lithium and sodium at 200 mM concentration were evaluated for their stabilizing effect on wild-type anti-CEACAM5 antibody and its antibody D, antibody E and antibody DE mutants. All salts improved the conformational stability of the four antibodies studied with the effect being most prominent for the antibody DE mutant ( FIG. 8 ). Of the salts studied, magnesium salts were most effective at increasing T m1 . 
     Example 6: Effects of Excipients on Viscosity and Osmolality of mAb Solutions 
     Effect of excipients at 200 mM concentration on viscosity of antibody solutions was also evaluated. Viscosity of antibody A and antibody C solutions (˜150 mg/mL) in presence and absence of aforementioned excipients was measured and compared with that in presence of traditional stabilizing excipients such as sucrose. Results indicated that the selected excipients either (i) significantly reduced solution viscosity compared to the control solutions ( FIG. 9 ) and/or (ii) resulted in solutions of lower viscosity ( FIG. 10 ) and lower osmolality ( FIG. 11 ) in comparison to sucrose at equipotent concentrations. For antibody C, solution viscosity could be reduced by 10×, compared to control, with arginine, lysine and magnesium salts being most effective followed by sodium and lithium ( FIG. 9 ). Antibody A solutions on the contrary were not too viscous to begin with (Control formulation in  FIG. 10 ). Addition of sucrose to these solutions, for improving conformational stability resulted in a significant increase in solution viscosity especially at concentrations higher than 10%. Such an increase in solution viscosity was not observed with any of the salts studied. The effect of the two excipient classes on solution viscosity was most apparent for solutions exhibiting a ΔT m1  of &gt;3° C. Results indicate that the viscosity liability associated with the use of sucrose at concentrations that are not too far from those generally employed for stabilizing protein formulations (˜8%) is essentially absent for excipients listed in this invention. A near-identical effect was observed in the context of solution osmolality as well ( FIG. 11 ). 
     Solutions containing 15% and 30% sucrose exhibited higher osmolality compared to 200 mM salt solutions without necessarily having a significantly higher stabilizing effect as measured by ΔT m1 .
