The present disclosure relates to the field of pharmaceutical formulations. Specifically, a stable pharmaceutical formulation for biotherapeutics is provided.
Biotherapeutics, which include macromolecule therapeutics, such as peptides, proteins, antibodies, polysaccharides, and nucleic acids; as well as cell-based therapeutics are a rapidly growing portion the therapeutics available to medical practitioners for treatment of a wide range of diseases and disorders. One reason for the success of biotherapeutics is the high specificity towards targets and superior safety profile as compared to small molecule therapeutics.
The structural complexity of biotherapeutics make them susceptible to physical or chemical degradation, which can result in structural and functional instability and reduced safety and efficacy. Although manufacturing and purification processes typically result in a high purity product, many biotherapeutics degrade over time, for example, during storage, transport and administration. Degradation can be due to chemical instability, which includes, but is not limited to, deamidation, isomerization, hydrolysis, racemization, beta-elimination, glycation, oxidation, adduct formation and disulfide scrambling; or physical instability, which includes, but is not limited to, denaturation, aggregation, precipitation, particle formation, and surface adsorption.
The composition of the pharmaceutical formulation for a biotherapeutic can significantly affect stability and, consequently, the safety and efficacy of the therapeutic. The pharmaceutical formulation also can affect the ease and frequency of administration and pain upon injection.
Surfactants are often included in pharmaceutical formulations to help stabilize the biotherapeutic and prevent aggregation or particle formation. Non-ionic surfactants such as polysorbate 80, polysorbate 20 and poloxamer 188 are commonly used in pharmaceutical formulations due to their proven safety profile.
However, polysorbate 80 and polysorbate 20 are known to be susceptible to degradation during storage by oxidative and hydrolytic pathways. Free fatty acids (FFA), one degradation product, can be sources of particle formation. Degradation can occur during storage of the polysorbate raw material, which can result in particle formation when the polysorbate surfactant is introduced into a pharmaceutical formulation. Degradation of the polysorbate surfactant in the pharmaceutical formulation can also result in aggregation. Additionally, degradation of polysorbates over time can result in an effective reduction in the amount of polysorbate in the formulations, adversely impacting the protective effect of the surfactant.
Despite advances made in the use of biotherapeutics and the knowledge relating to instability processes, there remains a need for pharmaceutical formulations with enhanced long-term stability. A formulation with improved long-term stability could help increase safety and efficacy of biotherapeutics. Thus, there remains a need for formulations that retain long-term stability under a variety of different manufacturing and storage conditions. The present invention satisfies this need and provides additional advantages as well.

Provided herein are stable pharmaceutical formulations for bioactive agents. In one aspect, the bioactive agent is a biotherapeutic. In one aspect, the biotherapeutic is a therapeutic macromolecule, such as a therapeutic polynucleotide or a therapeutic protein. In one aspect, the biotherapeutic includes cells. Long-term stability of a biotherapeutic can impact safety, consistency and efficacy of treatment. Loss of functionality within a preparation can decrease the effective concentration of the therapeutic for a given administration. Similarly, undesired modifications of a biotherapeutic can affect the activity or the safety of a formulation, which can result in loss of efficacy and increased risk of adverse side effects.
Non-ionic surfactants such as polysorbate 80, polysorbate 20 and poloxamer 188 are widely used in biotherapeutic formulations to protect against aggregation and particle formation. However, polysorbate 80 and polysorbate 20 are known to be susceptible to degradation during storage by oxidative and hydrolytic pathways, which can result in aggregation and particle formation when included in a pharmaceutical formulation. Additionally, these non-ionic surfactants are not easily removed from formulations, for example, using processes such as diafiltration. This can be problematic in the case of antibody intermediates used to generate antibody drug conjugates (ADC) because the presence of non-ionic surfactants may interfere with the conjugation process. Therefore, there is a need for alternate surfactants that can protect against aggregation and particle formation.
Provided herein is an alternate surfactant that can protect against aggregation and particle formation in therapeutic biomolecule formulations. In particular, provided herein are stable pharmaceutical formulations that contain D-α-Tocopheryl polyethylene glycol succinate (TPGS) as a surfactant. As demonstrated herein, inclusion of TPGS can reduce particle formation in a therapeutic macromolecule formulation even as compared formulations that include non-ionic surfactants such as polysorbate 80, polysorbate 20 or poloxamer 188.
D-α-tocopheryl polyethylene glycol succinate (TPGS) (also referred to as tocophersolan) is a water-soluble synthetic derivative of natural α-tocopherol (vitamin E), formed by covalently joining tocopherol succinate, an ester formed through esterification of tocopherol and succinic acid, to a polyethylene glycol (PEG) moiety via an esterification reaction. A schematic of the structure for TPGS is shown in
TPGS compositions typically contain a mixture of monomers and dimers, where a monomer includes a single vitamin E molecule covalently joined to a water-soluble moiety, such as a polyethylene glycol (PEG), through a linker, in which the water-soluble moiety, e.g., PEG, has a free, unreacted, terminal reactive group, e.g., a free terminal hydroxyl group. A dimer includes two vitamin E molecules covalently joined to a water-soluble moiety, such as a polyethylene glycol (PEG), through one or more linkers, where both ends of the water-soluble moiety, e.g., both terminal hydroxyl groups of a PEG moiety, have reacted with a linker that is joined to a vitamin E molecule so that there are no free terminal reactive groups, e.g., hydroxyl groups.

Surfactants are typically amphiphilic molecules that contain both hydrophilic and lipophilic groups. The hydrophile-lipophile balance (HLB) number can be used as a measure of the ratio between these groups and can have a value between 0-60, which defines the affinity of a surfactant for water or oil. Molecules with a HLB number greater than 10 have an affinity for water (hydrophilic) and molecules with a HLB number less than 10 have an affinity for oil (lipophilic). Non-ionic surfactants have HLB numbers ranging from 0-20. TPGS 1000 has a HLB number of 13.2. See, Wu and Hopkins. (1999). Characteristics of D-alpha-tocopheryl PEG1000 succinate for applications as an absorption enhancer in drug delivery systems. Pharm Tech. 23:52-60. The critical micelle concentration (CMC) is the concentration at and above which the surfactant forms micelles. Below the CMC, the surface tension decreases with increasing surfactant concentration. Above the CMC, additional surfactant added to the system forms micelles. TPGS 1000 has a CMC of 0.02% (w/w) at 37% C. See, Wu and Hopkins. (1999).

A naturally occurring antibody typically has a tetrameric form, with two pairs of polypeptide chains, each pair having one “light” and one “heavy” chain. The variable regions of each light/heavy chain pair form an antibody binding site. Typically, each light chain is linked to a heavy chain by one covalent disulfide bond although the number of disulfide linkages between the heavy chains of different immunoglobulin isotypes can vary. Each heavy and light chain also has regularly spaced intrachain disulfide bridges. Each heavy chain has a variable domain (VH) at one end and constant domains (CH) at the other end. Each light chain has a variable domain at one end (VL) and a constant domain (CL) at the other end. The constant domain of the light chain is typically aligned with the first constant domain of the heavy chain, and the light chain variable domain is aligned with the variable domain of the heavy chain. Light chains can be classified as either lambda chains or kappa chains based on the amino acid sequence of the light chain constant region. The variable domain of a kappa light chain may also be denoted as VK. Similarly, the variable domain of a lambda light chain may also be denoted as Vλ.
Bioactive agents can include immunoglobulin molecules of any isotype (e.g., IgG, IgE, IgM, IgD, IgA and IgY), subisotype (e.g., IgG1, IgG2, IgG3, IgG4, IgA1 and IgA2) or allotype (e.g., Gm, e.g., G1 m(f, z, a or x), G2m(n), G3m(g, b, or c), Am, Em, and Km(1, 2 or 3)).

As used herein, “unconjugated antibody intermediate” refers to an antibody, for example, a monoclonal antibody, to which a biologically active molecule can be conjugated to form the ADC. Typically, the biologically active molecule is conjugated to the antibody intermediate through a linker. In one aspect, the linker is cleavable. In one aspect, the linker is non-cleavable. In one aspect, the biologically active molecule is conjugated to the antibody intermediate using site-specific conjugation. In one aspect, the biologically active molecule is conjugated to the antibody intermediate using non-site-specific conjugation. There are generally six types of biologically active molecules that are used in making ADC: small molecules, for example, highly potent cytotoxic agents that can be used to kill tumor cells; protein toxins, such as Pseudomonas or diphtheria toxin, that can be used to kill tumor cells; cytolytic immunomodulatory proteins, such as Fas ligand, that can be used to kill targeted cells; biologically active peptides, such as GLP-1, that can be used to extend the pharmacological half-life of the antibody; enzymes, such as urease, that can be used to modify the biochemistry of the targeted microenvironment; and radionuclides, such as 90 Y or 111In, that can be used either to kill or image tumor cells.
In one aspect, the biologically active molecule conjugated to the antibody intermediate is a cytotoxic agent.

In one aspect, the ADC includes a biologically active agent conjugated to a monoclonal antibody through a linker. In one aspect, the linker is non-cleavable. In one aspect, the linker is cleavable. Generally, cleavable linkers exploit the differences in intracellular pH, reduction potential or enzyme concentration to trigger the release of the biologically active agent in the target cell. Cleavable linkers can include chemically labile linkers such as acid-cleavable linkers or reducible linkers; and enzyme-cleavable linkers such as peptide-based linkers or (3-glucuronide linkers. Cleavable linkers include, but are not limited to, linkers that include cleavable hydrazone, disulfide, peptide or thioether bonds. For example, cleavable linkers can include linker chemistries, including, but not limited to, hydrazone and hydrazide moieties, disulfide containing linkers such as N-succinimidyl-4-(2-pyridyldithio)pentanoate (SPP) and N-succinimidyl-4-(2-pyridyldithio)butyrate (SPDB), 4-(4′-acetylphenoxy)butanoic acid (AcBut) linkers, dipeptides valine-citrulline (Val-Cit) and phenylalanine-lysine (Phe-Lys) type linkers. Non-cleavable linkers rely on lysosomal proteolytic degradation of the antibody after internalization to release the biologically active molecule.
ADC present unique formulation challenges. Conjugation of a biologically active molecule to an antibody intermediate results in a molecule (the ADC) that can have different properties from the unconjugated antibody intermediate. For example, an antibody that exhibits acceptable aggregation behavior in its unconjugated form may behave differently in its conjugated form, for example, because of changes in surface properties or because the conjugate has altered the higher-order structure of the antibody. Although non-ionic surfactants such as polysorbate 80, polysorbate 20 and poloxamer 188 are widely used in biotherapeutic formulations to protect against aggregation and particle formation, these non-ionic surfactants are not easily removed from formulations, for example, using processes such as diafiltration. This can be problematic in the case of antibody intermediates used to generate antibody drug conjugates (ADC) because the presence of non-ionic surfactants may interfere with the conjugation process. Consequently, non-ionic surfactants such as polysorbate 80, polysorbate 20, and poloxamer 188 are often avoided in antibody intermediate formulations, despite the fact that formulations that lack a surfactant may be prone to particle formation. Advantageously, it has been found that inclusion of TPGS in an unconjugated antibody intermediate formulation does not interfere with the ADC conjugation process. In one aspect, a formulation is provided that includes an unconjugated antibody intermediate and TPGS as a surfactant.

In this example, the stability of four different antibodies was evaluated using three different surfactants and a no-surfactant control.
Each were formulated in 3 cc glass vials (1.1 mL volume) as described in the table below.
In separate 1.1 mL aliquots of the formulations containing test molecules, 0.02% TPGS (Vitamin E succinate with PEG-1000), 0.02% PS80 (polysorbate 80), 0.02% Poloxamer 188 (P188), 0.02% Kolliphor HS15 (Polyoxyl 15 Hydroxystearate), 0.02% Kolliphor EL (PEG-35 Castor Oil), 0.02% Kolliphor RH40 (PEG-40 Hydrogenated Castor Oil), or 1% PEG 300 (Polyethylene glycol 300) were added. A separate vial in which no surfactant was added was used as a control. Vials were subjected to three freeze-thaw cycles (3FT), and a shipping simulation procedure or vortex shaking for 2.5 h, respectively. Test molecule stability was assessed by visual inspection, micro-flow imaging (MFI), and high-pressure size exclusion chromatography (HPSEC).
Visual inspection of the samples was performed by examining the samples in their respective container for particles, color, and clarity using appropriate standards.
Detection of non-visible particles was performed using Micro Flow Imaging (MFI) using the 5200 series Micro-Flow Imaging system (available from Protein Simple) in accordance with the supplier's instructions.
HPSEC was performed using an Agilent HPLC system (Santa Clara, CA) with a TSK-Gel G3000 column for analysis. Briefly, 100 μg of antibody was loaded on the column by injecting 25 μl of the antibody diluted to 10 mg/ml in phosphate buffered saline. Standard integration parameters were used for automatic integration of aggregate, monomer and fragment peaks.
Test molecule stability was assessed by visual inspection, MFI, and HPSEC. Results from time zero (T0) and post shipping simulation (SS) are shown in
In the initial stability screen for the test molecules formulated in TPGS, Kolliphor HS15, Kolliphor EL, Kolliphor RH40, PEG 300, PS80, P188, or no surfactant (control), the MFI results in
To determine the effects of different surfactants on the stressed, accelerated and long term stability of the four test molecules, formulations of mAb-1, mAb-2, mAb-3, and mAb-4 at a concentration range of 50-150 mg/mL were spiked with 0.02% TPGS, PS80, or P188 and stored in 3 cc glass vials (with 1.3 mL fill) and stored at four different temperatures: 40° C., 25° C., 2-8° C., and −80° C. The stability of the formulations of test molecules containing surfactants was assessed via visual inspection, MFI, and HPSEC.
