Botulinum toxin is a neurotoxin produced by the Gram-positive anaerobic bacterium Clostridium botulinum. Botulinum toxin is classified into eight neurotoxins, seven of which (types A, B, C, D, E, F, and G) can cause paralysis of the nerves. Among them, the most lethal botulinum toxin known as a natural biological agent is type A, with the size of the toxin protein being about 150 kDa. In addition to the toxin protein, nontoxic complexing proteins are combined to form a complex, and the size of the complex can be formed up to 900 kDa depending on the type of neurotoxin.
Botulinum toxin has an effect of causing temporary relaxation paralysis of muscles, and its mechanism of action is known to cause local muscle paralysis by inhibiting the secretion of acetylcholine at the neuromuscular junction of the motor nerve endings (entering nerve cells by binding to the cholinergic endings of peripheral nerves). Botulinum toxin has an effect of suppressing pain caused by chronic myofascial pain, low back pain, muscle stiffness, and tension headaches by inducing localized muscle paralysis, which is believed to be due to the inhibition of acetylcholine release from the axon terminal of the neuromuscular junction, as known in the above mechanism of action, thereby blocking nerve signal transmission and resulting in pain suppression.
Botulinum toxin has been widely used for the purpose of improving strabismus and forehead wrinkles since it was approved by the US Food and Drug Administration (FDA) in 1989. Therapeutically, it is used for strabismus, facial tremors, eyelid spasms, muscle stiffness, and for cosmetic purposes, it is used for wrinkle removal and square jaw procedures.
The duration of botulinum toxin injected into muscle and skin tissues is within 3 to 6 months, and the injection effect begins within 3 days and the maximum effect appears between 1 and 2 weeks. As the nerve signal transmission is blocked by the inhibition of acetylcholine secretion at the neuromuscular junction by botulinum toxin, and then the effect of nerve paralysis by botulinum toxin is reduced as new nerve branches are generated, regular administration of botulinum toxin is essential.
Meanwhile, hyaluronic acid is an anionic non-sulfated glycosaminoglycan (GAGs) widely distributed in connective, epithelial, and neural tissues, and is one of the main components of the extracellular matrix. It mainly contributes to cell proliferation and migration and is used as one of the biocompatible biomaterials for the purpose of treating diseases such as osteoarthritis as a main component of pharmaceuticals or as an additive for providing viscosity in liquid formulations.
Protein pharmaceuticals such as botulinum toxin have a very narrow range of formulation choices due to the influence of tertiary structure denaturation on the pharmacological activity of the drug. In particular, among various factors affecting the tertiary structure denaturation of botulinum toxin, the moisture content in the finished product has a significant impact on the stability of efficacy. This is one of the reasons why existing botulinum toxin formulations are limited to vacuum-dried injectables or freeze-dried injectables, where moisture in the finished product is sufficiently removed.
Moreover, vacuum-dried injectables or freeze-dried injectables require users to dilute them for use, leading to potential safety issues due to variations in the administration of the main component depending on the user's dilution method or management state, and also have the disadvantage of reduced user convenience.
Therefore, it is crucial to develop a liquid formulation that can maintain the pharmacological activity of the enclosed botulinum toxin while enhancing user convenience. Many prior studies have been conducted to develop liquid stabilizing formulations for botulinum toxin in response to such demand, but most of the research results have failed to maintain the initial biological activity of botulinum toxin. Consequently, low-temperature storage to ensure the pharmacological stability of botulinum toxin contained in liquid formulations is being spotlighted as the most realistic alternative, and there remains a technical challenge to overcome in securing the low-temperature storage stability with a novel additive that can maintain the pharmacological activity of botulinum toxin in the liquid formulation.

Experimental Materials and Methods
1. Preparation of Botulinum Toxin Liquid Composition
To evaluate the biological activity retention of botulinum toxin depending on the type and concentration of additives, botulinum toxin liquid formulations containing hyaluronic acid and additives such as sugars, non-ionic surfactants, stabilizers, or their combinations were prepared. Specifically, hyaluronic acid (molecular weight of hyaluronic acid used in Examples 1 to 4=1 MDa, molecular weight of hyaluronic acid used in Example 5=3 MDa) was dissolved in 0.9% (w/v) sodium chloride solution to a concentration of 10 mg/mL. Next, additive candidate materials were dissolved individually or in a combination of two or more additives in a 50 mM sodium phosphate buffer (pH 6.0), and added to the hyaluronic acid solution at 10% (v/v). Botulinum toxin was added to the prepared hyaluronic acid-additive mixture to a final concentration of 20 units/mL, followed by stirring and mixing for 1 hour. The botulinum toxin liquid composition prepared as described above was stored at 4° C.
2. Animal Potency Test 1—Stability Evaluation of Botulinum Toxin Depending on Additives
The animal potency test was conducted by injecting 0.1 mL of liquid compositions of the present invention, prepared with various concentrations of diluted additives individually or in a combination of two or more additives, into the abdominal cavity of ICR-mice (5 weeks old, weight: 19-22 g, 10 mice per group), and the number of dead mice was observed for 3 days. A statistically significant retention of biological activity was evaluated for groups that showed a mortality rate of 70% or more. Considering the sampling error due to the viscosity of the composition and other experimental errors, groups with mortality rates below the standard were subjected to additional confirmation tests in the next cycle, and groups with mortality rates above the standard continued with the tests. Other animal potency test results in the present invention were performed in the same manner as described above.
3. Animal Potency Test 2—Calculation of Potency and Specific Potency
Liquid compositions of the present invention, prepared with various concentrations of diluted additives individually or in a combination of two or more additives, were injected into the abdominal cavity of ICR-mice (5 weeks old, weight: 19-22 g, 10 mice per group) at 0.1 mL per mouse, and the number of dead mice was observed for 3 days. The activity of botulinum toxin was calculated using a statistical program (Combistats, version 4.0, EDQM) based on the obtained data.
A screening experiment was conducted for various types of sugars excluding the sugar used as an additive in conventional botulinum toxin liquid formulations, and lactose monohydrate and fructose were selected as the final candidates. Animal potency test 1, as described in Chapter 2 of the experimental materials and methods, was performed after adding lactose monohydrate or fructose at different amounts.
The results are shown in Table 1 and
Screening experiments were performed on various types of non-ionic surfactants, excluding the non-ionic surfactants that are being used as additives in conventional botulinum toxin liquid formulations, including surfactants containing non-ionic surfactants. As a result, polyoxyethylene (40) hydrogenated castor oil (referred to as ‘HCO-40’) was selected as the final candidate. Subsequently, animal potency test 1 described in section 2 of the experimental materials and methods was conducted after adding HCO-40 in different concentrations.
As shown in Table 2 and
Screening experiments were conducted on various types of stabilizers, excluding the stabilizers that are being used as additives in conventional botulinum toxin liquid formulations, and as a result, glycerin was selected as the final candidate. Subsequently, animal potency test 1 described in section 2 of the experimental materials and methods was conducted after adding glycerin in different concentrations.
As shown in Table 3 and
Referring to the animal test results of the individual additives performed in Examples 1 to 3, each additive was mixed in various combinations, and the stability was verified. However, in the case of fructose, a concentration of 2.5% (w/v) was added, which was the median value of the concentration used in the test group where it was added individually. A sample without any additives was used as a negative control. Periodic animal testing was conducted on the test group that met the criteria for maintaining the stability of the set botulinum toxin. The composition of the entire test group is shown in the table below.
The results are shown in Table 4 and
In particular, according to the mouse mortality rates measured during the periods of 0, 3, 6, 10, 15, 20, 25, 36, and 52 weeks, it was found that the botulinum toxin in test group 1 [containing HCO-40 0.2% (w/v)], test group 2 [containing fructose 0.5% (w/v), HCO-40 0.2% (w/v)], test group 4 [containing fructose 0.5% (w/v), HCO-40 0.2% (w/v), glycerin 1% (w/v)], and test group 7 [containing fructose 0.5% (w/v), HCO-40 0.05% (w/v), glycerin 1% (w/v)] satisfied the stability criterion (showing a mortality rate of 70% or higher for all observation periods up to 20 weeks). In particular, it was confirmed that test group 3 [containing HCO-40 0.2% (w/v), glycerin 1% (w/v)] and test group 4 [containing fructose 0.5% (w/v), HCO-40 0.2% (w/v), glycerin 1% (w/v)] maintained high mortality rates of 80% or more even in the 52nd week, thus achieving long-term stability of botulinum toxin for more than 12 months when additives that meet the above composition are mixed.
Referring to the results of animal tests performed with the individual addition of additive candidates in Examples 1 to 3, the stabilization efficacy was confirmed after mixing each additive in various combinations. Exceptionally for fructose, 2.5% (w/v) was added, which is the median concentration used in the test group with individual addition. A sample without any additives was used as a negative control. Periodic animal tests were conducted for test groups meeting the criteria for maintaining the stability of the botulinum toxin. Experiments were conducted for test groups 1 to 11, and the composition of additives in each test group is the same as in the additive composition table of Example 4.
The results are presented in Table 5 and
In particular, botulinum toxin in test group 1 [containing 0.2% (w/v) HCO-40], test group 4 [containing 0.5% (w/v) fructose, 0.2% (w/v) HCO-40, and 1% (w/v) glycerin], and test group 6 [containing 0.05% (w/v) HCO-40 and 1% (w/v) glycerin] not only met the stability criteria (showing a mortality rate of 70% or more during all observation periods) but also demonstrated a high mortality rate of 80% or more at week 52, confirming that the long-term stability effect of botulinum toxin lasting for 12 months or more can be achieved when the additives satisfying the above composition are mixed.
The description of the present invention as described above is for illustrative purposes only, and those of ordinary skill in the technical field to which the invention pertains will understand that the technical idea or essential features of the invention can be easily transformed into other specific forms without changing. Therefore, the examples described above should be understood as being exemplary in all respects and not limiting.
The present invention can significantly increase the stability during long-term storage of botulinum toxin by providing a liquid composition that includes an additive for maintaining the pharmacological activity of the active ingredients, botulinum toxin, and hyaluronic acid. By combining pH regulators, sugars, surfactants, stabilizers, and other additives at specific concentrations and adding them to the botulinum toxin liquid formulation, it demonstrates excellent effects in preventing physical and chemical instability and the denaturation of the tertiary structure of the botulinum toxin. Thus, the use of the composition according to the present invention can expand the application forms of existing botulinum toxin, which were limited to dry formulations, to liquid formulations, and thus various types of products can be developed. Therefore, it is expected to be utilized in various industrial fields.
Furthermore, the increased stability of botulinum toxin in the liquid state utilizing the composition of the present invention can guarantee stability during the formulation process of botulinum toxin, and it can be applied to controlled-release injectable drug formulations in sustained-release or immediate-release forms, or can be utilized in the development of transdermal drugs using microstructures such as microneedle patches. In addition, the active ingredient, hyaluronic acid, which is excellent in biocompatibility, can provide an additional anti-inflammatory effect and confer viscosity within the final product, thereby expecting localized therapeutic effects of botulinum toxin. Therefore, the composition of the present invention is expected to be useful in various therapeutic fields where botulinum toxin can be applied.
