Abstract
Description
[Technical field]
[0001] The present invention relates to a stable nanomicelle ophthalmic solution containing cyclosporine and a method for preparing the nanomicelle solution.The present invention further relates to a stable nanomicelle solution containing cyclosporine forms with characteristic XRD peaks at 6.9, 7.8, 9.4, and 15.9 2-theta (degrees), or amorphous cyclosporine.The present invention further relates to a stable nanomicelle solution containing cyclosporine forms with characteristic XRD peaks at 7.4, 8.7, 14.4, and 17.5 2-theta (degrees), or cyclosporine forms with characteristic XRD peaks at 8.5, 9.3, 11.6, and 20.3 2-theta (degrees).The present invention also relates to the use of this stable nanomicelle ophthalmic solution in dry eye. [Background technology]
[0002] A cyclosporine nanomicelle ophthalmic solution is generally disclosed in US Patent No. 10,918,694, which comprises 0.087-0.093% by weight of cyclosporine, polyoxyl lipid or fatty acid, and polyalkoxylated alcohol. Preferably, it comprises 0.087-0.093% by weight of cyclosporine, 0.5-5% of one or more selected from the group consisting of HCO-40, HCO-60, HCO-80, and HCO-100, and about 0.01-0.1% of octoxynol-40. Further, a method of preparing such a cyclosporine solution is disclosed. The method comprises dissolving cyclosporine in a polyoxyl castor oil, such as hydrogenated castor oil, and a polyalkoxylated alcohol, such as octoxynol, at 60° C. before adding to the aqueous phase. Specifically, the method of preparing the ophthalmic solution comprises the following steps: HCO-40 is melted in a flask heated to about 60°C with stirring. Once liquefied, the required amount of cyclosporine is added and mixed until dissolved and uniform. Octoxynol-40 is then heated to about 60°C and once liquefied, it is added to the cyclosporine HCO-40 mixture. Water for injection at about 25°C is charged to the flask containing the dissolved cyclosporine and stirred until dissolved. Other excipients such as sodium chloride and phosphate buffer are then added, followed by PVP-K90, mixed until dissolved, and made up to final volume with water for injection. However, current methods have the problem that when dissolving cyclosporine in polyoxyl castor oil such as HCO-40, there may be differences in the stability of different batches during production due to differences in the solubility and stability of different forms of cyclosporine. As a result, some batches are not stable and cyclosporine precipitates out of solution.
[0003] Furthermore, different forms of cyclosporine exhibit different solubilities and stabilities. Although cyclosporine with characteristic XRD peaks at 2-theta (degrees) 6.9, 7.8, 9.4, and 15.9 is the most soluble form of cyclosporine and is useful for preparing solution formulations, it is not the most stable form and may convert to a less soluble form of cyclosporine, thus affecting the stability of the solution. This form may convert to a more stable, more soluble cyclosporine with characteristic XRD peaks at 2-theta (degrees) 7.4, 8.7, 14.4, and 17.5 during dissolution of cyclosporine in a surfactant at 55-60°C. In turn, this may change to another more soluble form of cyclosporine with characteristic XRD peaks at 2-theta (degrees) 8.5, 9.3, 11.6, and 20.3. Furthermore, the amorphous form, which is also one of the more soluble forms and is useful for preparing solution formulations, may also recrystallize into these two less soluble forms. Such conversion is driven by several factors, including but not limited to moisture, water, solvent temperature, etc. This conversion is also dependent on temperature, stresses such as prolonged storage at elevated temperatures, etc. The process requires modification depending on the form of cyclosporine used, as the amorphous form, as well as forms with characteristic XRD peaks at 6.9, 7.8, 9.4, and 15.9 2-theta (degrees), require wetting followed by complete dissolution at temperatures up to 70°C. However, when less soluble forms are used, temperatures as high as 130°C are required. Furthermore, due to instability and conversion during the manufacturing steps, the solutions should be manufactured with strict control of API specifications, process temperatures, and times to avoid interconversion of the forms. It is somewhat difficult to determine the extent to which this conversion has occurred prior to completing the manufacturing process to obtain nanomicellar cyclosporine. This can result in the formation of seeds within the composition, either early in the process or during storage at higher temperatures, which subsequently crystallize out of the drug product, rendering the product useless. Soft mesophase or liquid crystalline forms of cyclosporine formed as non-aqueous phase intermediates can be a source of such instability.
[0004] Therefore, there is a need for a stable formulation and a method for preparing the same to prevent conversion to less soluble forms of cyclosporine during the manufacturing process and during storage. The present invention discloses a stable nanomicelle ophthalmic formulation and an improved method for making such a stable formulation. The method for making the formulation results in a stable formulation regardless of the form of cyclosporine used in the formulation. The method does not result in conversion of one form to another. More specifically, the method does not result in conversion of a dissolved form of cyclosporine to a less soluble form of cyclosporine, and further prevents precipitation of cyclosporine in the formulation during long-term stability. Summary of the Invention
[0005] According to some embodiments, one of the objects of the present invention is to provide a method for the preparation of a medicament for use in a pharmaceutical composition comprising: A method for making a stable nanomicellar ophthalmic formulation comprising cyclosporine, hydrogenated 40 polyoxyl castor oil, octoxynol-40, and an aqueous vehicle, comprising: The ophthalmic preparation is a) mixing cyclosporine with hydrogenated 40 polyoxyl castor oil at a temperature of 55° C.±2° C. or higher to form mixture A; b) prior to complete dissolution of the cyclosporine, reducing the temperature of mixture A to a temperature of 35° C.±2° C. and adding octoxynol-40; c) mixing the resulting mixture with an aqueous vehicle.
[0006] The inventors have surprisingly found that the solution stability of cyclosporine A at 35°C-40°C is greater than the solution stability at 55°C-60°C, and therefore, by reducing the temperature to 35°C-40°C, the above-mentioned stability concerns of the formulation are overcome and a more stable formulation is provided.
[0007] In another aspect, the present invention provides a method for producing a composition comprising: A stable nanomicelle ophthalmic formulation comprising cyclosporine, hydrogenated 40 polyoxyl castor oil, octoxynol-40, and an aqueous vehicle, The ophthalmic preparation is a) mixing cyclosporine with hydrogenated 40 polyoxyl castor oil at a temperature of 55° C.±2° C. or higher to form mixture A; b) prior to complete dissolution of the cyclosporine, reducing the temperature of mixture A to a temperature of 35° C.±2° C. and adding octoxynol-40; c) mixing the resulting mixture with an aqueous vehicle.

[0013] Surprisingly, it has been found that while the mixture is held under vacuum, the air bubbles are drawn out and accumulate on the surface, from which the air bubbles are gradually removed, resulting in a clean bottom.Therefore, dissolving under vacuum or intermittent removal of bubbles during dissolving may result in faster dissolution and may not require lowering the temperature of the mixture.This overcomes the above-mentioned stability concerns of the formulation and provides a more stable formulation.

[0065] Another embodiment of the present disclosure is A method for making a stable nanomicelle ophthalmic formulation comprising cyclosporine, a polyoxyl lipid or fatty acid, and a polyalkoxylated alcohol, the ophthalmic formulation comprising: a) mixing cyclosporine with polyoxyl lipids or fatty acids at a temperature of 55° C. or higher to form mixture A; b) reducing the temperature of mixture A to a temperature below 40° C. prior to complete dissolution of cyclosporine.
[0066] Preferably, mixing the cyclosporine with the polyoxyl lipid or fatty acid is carried out at a temperature of 55°C to 60°C to form mixture A. Preferably, mixture A is cooled to a temperature of 35°C to 40°C before complete dissolution of the cyclosporine. More preferably, mixing the cyclosporine with the polyoxyl lipid or fatty acid is carried out at a temperature of 55°C ± 2°C to form mixture A, and mixture A is cooled to a temperature of 35°C ± 2°C or less before complete dissolution of the cyclosporine. Further, the method includes adding a polyalkoxylated alcohol and then mixing the resulting mixture with an aqueous vehicle at 35°C ± 2°C. In another embodiment, the resulting mixture is mixed with an aqueous vehicle at a temperature of 55°C ± 2°C.
[0067] Another embodiment of the present disclosure is A method for making a stable nanomicellar ophthalmic formulation comprising cyclosporine, a polyoxyl lipid or fatty acid, and a polyalkoxylated alcohol, and an aqueous vehicle, comprising: The ophthalmic preparation is a) mixing cyclosporine with polyoxyl lipids or fatty acids at a temperature of 55°C ± 2°C or higher to form mixture A; b) holding mixture A under vacuum to remove bubbles; c) optionally, prior to complete dissolution of the cyclosporine, reducing the temperature of mixture A to a temperature of 35° C.±2° C. and adding the polyalkoxylated alcohol; and d) mixing the resulting mixture with an aqueous vehicle.
[0068] In one embodiment, the aqueous vehicle is mixed at a temperature of 35° C.±2° C. In another embodiment, the aqueous vehicle is mixed at a temperature of 55±2° C.
[0069] It has been found that during dissolution of hydrophobic molecules such as cyclosporine A (CsA) in polyoxyl lipids such as polyoxyl hydrogenated castor oil, air is trapped in the bulk in the form of bubbles, creating foam. This occurs regardless of the temperature during the drug dissolution process, even when the temperature is reduced to 55°C or even 35°C. This may delay the wetting and dissolution of cyclosporine, as this trapped air may create an interface between the cyclosporine particles and the water. Surprisingly, it has been found that while the mixture is held under vacuum, the air bubbles are dragged out and accumulate on the surface, from which they are gradually removed, leaving a clean bottom. Thus, dissolution under vacuum or intermittent removal of bubbles during dissolution may result in faster dissolution and eliminate the need to reduce the temperature of the mixture.

Bioadhesion refers to the ability of certain synthetic and biological macromolecules, as well as hydrocolloids, to adhere to biological tissues. Bioadhesion is a complex phenomenon that depends in part on the properties of the polymer, the biological tissue, and the surrounding environment. Several factors have been found to contribute to the bioadhesive ability of a polymer: the presence of functional groups capable of forming hydrogen bridges (--OH, COOH), the presence and strength of anionic charges, sufficient elasticity for the polymer chain to penetrate the mucosal layer, and high molecular weight. Bioadhesive systems have been used in dental, orthopedic, ophthalmic, and surgical applications. However, recently, significant interest has emerged in the use of bioadhesive materials in other areas, such as soft tissue-based artificial replacements and controlled release systems for localized release of bioactive agents. Such applications include systems for the release of drugs in the oral or nasal cavity, and systems for intestinal or rectal administration.

In one embodiment, the optional one or more bioadhesive polymers are present in the composition at about 0.01% to about 10% by weight / volume, preferably about 0.1 to about 5% by weight / volume.

[0188] Further disclosed herein are stable nanomicelle ophthalmic formulations in which the mixed nanomicelle size and polydispersity index were determined with a Zetasizer (Malvern Instruments, NJ). Briefly, approximately 1 ml of each formulation was transferred to a cuvette and placed in the instrument. A laser beam was used to determine the mixed nanomicelle size. Nanomicelles contemplated by the present disclosure typically range in size from about 1-100 nm, in some embodiments the size ranges from about 5-50 nm, in some embodiments the size ranges from about 10-40 nm, and in some embodiments the size ranges from about 13-16 nm.
[0189] In another embodiment, the present disclosure relates to cyclosporine forms having characteristic XRD peaks at 6.9, 7.8, 9.4, and 15.9 2-theta (degrees).
[0190] In yet another embodiment, the present disclosure relates to a stable nanomicellar ophthalmic formulation comprising an amorphous form of cyclosporine.
[0191] In yet another embodiment, the present disclosure relates to a stable nanomicellar ophthalmic formulation substantially free of cyclosporine forms having characteristic XRD peaks at 7.4, 8.7, 14.4, and 17.5 2-theta (degrees).
[0192] In yet another embodiment, the present disclosure is a stable nanomicellar ophthalmic formulation that is substantially free of cyclosporine forms having characteristic XRD peaks at 8.5, 9.3, 11.6, and 20.3 2-theta (degrees). The XRD data for these cyclosporine forms is presented in FIG. 2.
[0193] The competitive dissolution time of cyclosporine depends on the amount of cyclosporine A dissolved based on the batch size. In general, the dissolution time of cyclosporine in hydrogenated 40 polyoxyl castor oil (Kolliphor® RH 40) was found to be 130 minutes or more at a ratio of 9:10 (cyclosporine:Kolliphor® RH 40). Cyclosporine A slowly dissolved over a period of time with stirring, and during this complete dissolution period the solution became clear. If cyclosporine A reprecipitates during the dissolution period, it is possible that a slightly cloudy solution migrated to the aqueous phase during batch manufacture. This may initiate a seeding effect on crystal growth in the final formulation during storage, leading to batch failure. Based on these observations, the dissolution behavior of cyclosporine was tested in hydrogenated 40 polyoxyl castor oil (Kolliphor® RH 40) at 55° C. and 35° C. It was found that the solution stability at 35° C. was relatively higher than that at 55° C. (see Example 2 in Table 4). Based on the above observations, if cyclosporine was not completely dissolved in Kolliphor® RH 40 at 55° C., it is believed that the temperature can be reduced to 35° C. This is because the solution stability of cyclosporine at 35° C. is higher than that at 55° C.
[0194] In another embodiment, when cyclosporine is present in a form having characteristic XRD peaks at 7.4, 8.7, 14.4, and 17.5 2-theta (degrees) (FIG. 2B), cyclosporine is mixed with hydrogenated polyoxyl castor oil at a temperature of 127-130° C. until completely dissolved, and octoxynol-40 is added to the mixture at 127-130° C.
[0195] In another embodiment, when cyclosporine is present in a form having characteristic XRD peaks at 8.5, 9.3, 11.6, and 20.3 2-theta (degrees) (FIG. 2C), cyclosporine is mixed with hydrogenated polyoxyl castor oil at a temperature of 127-130° C. until completely dissolved, and octoxynol-40 is added to the mixture at 127-130° C.

[0253] The following examples have been prepared to illustrate non-limiting embodiments of the present disclosure.
[0254] Example 1 [Table 1]
[0255] Cyclosporine nanomicelle ophthalmic solution was prepared as follows: In Example 1(a), polyoxyl 40 hydrogenated castor oil (Kolliphor® RH 40) was melted at 55-60°C with stirring at about 200 rpm. Cyclosporine A was added to the melted Kolliphor® RH 40 at 55-60°C and the reaction mixture was mixed at the same temperature range until completely dissolved. After Cyclosporine A was dissolved, a surfactant (Octoxynol-40) was added under stirring and after stirring for 10 minutes, this non-aqueous solution was delivered to 90% water for injection at 55-60°C. The temperature of the water for injection was maintained below 22°C. Sodium phosphate monobasic, sodium phosphate dibasic, sodium chloride, and povidone were added sequentially to the bulk solution under stirring until completely dissolved. When all components were completely dissolved in the bulk solution, the volume was made up to 100% with water for injection to 1 L. In Example 1(b), the procedure of Example 1(a) was followed except that the solution of cyclosporine A in Kolliphor® RH 40 at 55-60° C. was added to the water immediately after it began to become cloudy.
[0256] Both batches of Example 1(a) and Example 1(b) were filled into three 5 mL low density polyethylene (LDPE) vials in a sterile area. The vials were exposed to accelerated temperatures of 40° C. and 30° C. in a chamber (to accelerate particle formation). Samples were visually inspected daily for any signs of turbidity and / or visible particle formation. The two batches were analyzed for critical quality parameters such as assays for cyclosporine, pH, osmolality, and micelle size, all of which were found to be well within specifications. The results are provided in Table 2 below. Figure 1 shows photographs of a stable batch (Example 1a) and an unstable batch (Example 1b). [Table 2]
[0257] The data in Table 2 show that when batches are made using a clear CsA non-aqueous phase (cyclosporine in Kolliphor® RH 40 and Octoxynol-40) and then the mixture is added to the aqueous phase, the batches remain stable for a longer period of time. However, when batches are made using a cloudy cyclosporine non-aqueous phase and then the mixture is added to the aqueous phase, the batches show less stability. This indicates that non-uniform distribution of cyclosporine within the micelles may promote nucleation and particle formation in the final product upon storage.
[0258] Example 2 Solution stability of cyclosporine A lots in polyoxyl 40 hydrogenated castor oil (Kolliphor® RH 40) at 55-60 °C is a critical process parameter for a stable formulation. Surprisingly, it was also found that the dissolution behavior changed over storage time, as shown in Table 3. [Table 3]
[0259] Example 3 Similarly, the dissolution behavior test of Cyclosporine A in polyoxyl 40 hydrogenated castor oil (Kolliphor® RH 40) was examined at 35° C. Table 4 shows the results of the dissolution behavior test of Cyclosporine A in Kolliphor® RH 40 at 35° C. As can be seen from Table 4, the solution stability at 35° C. was found to be relatively higher than that at 55° C. [Table 4]
[0260] As can be seen from Table 4, if Cyclosporine A is not completely dissolved in Kolliphor® RH 40 at 55° C., the temperature can be reduced to 35° C. Based on this data, the solution stability of Cyclosporine A at 35° C. is believed to be greater than that at 55° C. The complete dissolution step of Cyclosporine A in Kolliphor® RH 40 was modified as follows: (i) Dispersing the API for 20 minutes at 55°C ± 2°C and stirring for an additional 15 minutes; (ii) The temperature is then reduced from 55° C.±2° C. to 35° C.±2° C. in less than 55 minutes (approximately 40 minutes) and the solution is stirred at 35° C.±2° C. until complete dissolution of the API is achieved; (iii) Octoxynol-40 was added with stirring and the non-aqueous phase was delivered to water for injection at 35° C.±2° C.
[0261] This change in the dissolution process accommodates lot-to-lot variability in solution stability of the API in Kolliphor® RH-40 at 55° C. and can also accommodate variability during storage.
[0262] Example 4 The dissolution behavior of the three cyclosporine forms disclosed in Figure 2 was tested in polyoxyl 40 hydrogenated castor oil (Kolliphor® RH 40) at 55°C. The results are shown in Table 5. [Table 5]
[0263] 3(a)-3(d) are photographs of the results of the tests reported in Table 5.
[0264] As can be seen from Table 5 above and the associated figures, the CsA forms having characteristic XRD peaks at 7.4, 8.7, 14.4, and 17.5 2-theta (degrees), as well as the CsA forms having characteristic XRD peaks at 8.5, 9.3, 11.6, and 20.3 2-theta (degrees), are much less soluble compared to the CsA forms having characteristic XRD peaks at 6.9, 7.8, 9.4, and 15.9 2-theta (degrees). During dissolution of cyclosporine in Kolliphor® RH 40 at 55° C., the CsA forms having characteristic XRD peaks at 6.9, 7.8, 9.4, and 15.9 2-theta (degrees) may change to a less soluble form, or the amorphous cyclosporine may recrystallize to a relatively less soluble form. This transformation may be dependent on stresses on the system, including temperature, extended storage periods at elevated temperatures, etc. For this purpose, cyclosporine ophthalmic formulations were exposed to higher temperatures and times and PXRD data was obtained from the precipitated portion. As shown in Figure 4, the precipitate was found to be close to the CsA form with characteristic XRD peaks at 6.9, 7.8, 9.4 and 15.9 2-theta (degrees). Since this CsA form has low solubility in water, its use may result in a seeding effect either at the initial stage or during storage at higher temperatures, thus leading to batch failure.
[0265] In another attempt, the behavior of CsA in Kolliphor® RH 40 alone in the absence of water is determined. CsA was dissolved in Kolliphor® RH 40 at 55° C. and held for a longer time until precipitation occurred. The precipitated portion was separated and PXRD was performed. As shown in FIG. 5, cyclosporine was found to have characteristic XRD peaks at 8.5, 9.3, 11.6, and 20.3 2-theta (degrees). As a result, the process disclosed in the present disclosure, which reduces the exposure of cyclosporine to Kolliphor® RH 40 at, for example, 55° C., can minimize this precipitation phenomenon, which may be due to the possible conversion of cyclosporine to the less soluble CsA form. Thus, the present disclosure provides, among other things, improved storage stability.

Preparation method of nanomicelle solution Polyoxyl 40 hydrogenated castor oil (Kolliphor® RH40) was heated to approximately 50-60°C until liquefied and then introduced into a 10 L glass vessel.

If Octoxynol-40 solidified, it was added after heating at approximately 50-60°C until liquefied.

With stirring, the API blend was added to the mixing tank at 55±2° C. and the remaining excipients were added in the following order with stirring: sodium phosphate monobasic, then sodium phosphate dibasic, then sodium chloride, then polyvinylpyrrolidone, while stirring for approximately 15 minutes.
