Abstract
Description
Technical Field
[0001] This invention relates to the field of pharmaceutical formulation technology, and more specifically to a pharmaceutical composition comprising a benzonitrile derivative. Background Technology
[0002] The storage conditions of pharmaceutical products reflect their stability. Drugs or crystalline forms with lower melting points generally have relatively poor stability and require storage at lower temperatures, while those with higher melting points or crystalline forms have better stability and can generally be stored at room temperature. The optimal processing temperature for formulations should also be determined based on the thermal stability of the drug. The thermal degradation of drugs is usually closely related to their melting point, and degradation reactions occur rapidly above 20°C. Fatty liver and cancer both require long-term medication. The requirement for low-temperature storage will add considerable inconvenience to patients taking medication long-term and may lead to missed doses or improper storage, which may affect treatment efficacy and potentially delay or relapse of the disease. Furthermore, low-temperature refrigeration requires dedicated cold chain transportation vehicles and long-term refrigerators, which adds extra costs to the commercial development of the product. Therefore, to better meet clinical and commercial needs, it is necessary to find a stable pharmaceutical formulation and preparation method that can be stored at room temperature. Such a formulation will not only significantly increase the in vivo and in vitro solubility of the active ingredient, but more importantly, it will allow for storage at room temperature. The molecular formula of the compound shown in formula (I) is: C 24 H 24 N4O3, its structural formula is shown below:
[0003]
[0004] The equilibrium solubility of crystal form III and crystal form VI of the compound shown in formula (I) in different media without the addition of surfactant is shown in Table 1. This indicates that the equilibrium solubility of the active pharmaceutical ingredient of this compound is pH-dependent, and reasonable solubilization methods are required to increase its dissolution in vivo and in vitro.
[0005] Table 1 shows the equilibrium solubility of the compounds represented by formula (I) in media with different pH values.
[0006]
[0007]
[0008] Furthermore, the compound shown in formula (I) is slightly unstable at a high temperature of 60°C, and after 15 days of accelerated reaction, the total impurities increase by 0.31%. The excipient polyethylene glycol 6000 is unstable for GL01 at high temperatures. Specifically, after 15 days of accelerated reaction at 60°C, the total impurities may increase by 2.9%, with a significant increase in related substances. This is because polyethylene glycol 6000 has a low melting point (DSC results show that the melting point of polyethylene glycol 6000 is 58.6°C). After 15 days of accelerated reaction at 60°C, polyethylene glycol 6000 is semi-solid. It may undergo a condensation reaction with the compound shown in formula (I) at high temperatures, condensing with the hydroxyl groups and secondary amines therein to form unknown impurities.
[0009] Therefore, there is still a need to develop a formulation that will allow pharmaceutical compositions containing compounds of formula (I) to be stored stably for extended periods at temperatures of 25°C to 60°C and at high relative humidity, and will have significantly better dissolution performance.

[0070] Example
[0071] 1. Screening of solubilizing excipients
[0072] This invention uses the improvement of GL01's dissolution rate in various dissolution media as an evaluation index to screen the types of solubilizing excipients.
[0073] Considering that the solubility of GL01 active pharmaceutical ingredient is pH dependent, the solubilizing effect of several common solubilizing excipients on GL01 was investigated. They were prepared according to Table 2 and added to 250 ml of pH 6.8 phosphate buffer solution. The mixture was shaken in a constant temperature shaker at 37°C and samples were taken at 2 hours and 24 hours. The percentage of GL01 dissolved is shown in Table 2.
[0074] Table 2. Study on the solubilizing effect of several common solubilizing excipients on GL01.
[0075]
[0076]
[0077] As shown in Table 2, compared to other excipients, polyvinylpyrrolidone VA64 (trade name: VA64 significantly improves the solubility of GL01 in pH 6.8 phosphate buffer. Polyvinylpyrrolidone VA64 (trade name: VA64) was selected. VA64) and polyvinylcaprolactam-polyvinyl acetate-polyethylene glycol graft copolymer (trade name: VA64) To conduct subsequent experiments.
[0078] 2. Screening of different solubilizing excipients and processes
[0079] Method 1: Normally, drugs are transported through the human gastrointestinal tract first through the stomach (pH approximately 1.0-4.5), then to the small intestine (pH approximately 4.5-6.8) for absorption. To more accurately reflect the dissolution of GL01 in vivo, this invention employs more stringent dissolution conditions. Specifically, referring to Method 1 of the Dissolution and Release Determination Method for Enteric-coated Formulations in Part IV, 0931 of the 2020 edition of the Chinese Pharmacopoeia, the following procedure was followed: 750 ml of pH 1.0 hydrochloride buffer was stirred at 75 rpm for 1 hour, then 250 ml of sodium phosphate solution was added to adjust the pH to 6.8 before conducting the dissolution test (hereinafter referred to as the pH 1.0 followed by pH 6.8 dissolution method).
[0080] Method 2: As shown in Table 1, the equilibrium solubility of GL01 is relatively low at pH 6.8. This pH condition corresponds to the small intestine, the site of absorption in vivo, and is therefore representative. The specific procedure followed the paddle method, Part II, General Chapter 0931, Dissolution and Release Determination, of the Chinese Pharmacopoeia 2020. The medium was pH 6.8 phosphate buffer, hence this condition was chosen for the dissolution test (hereinafter referred to as the pH 6.8 dissolution method).
[0081] To improve the ability to distinguish dissolution conditions, a relatively stringent rotation speed of 50 rpm was selected for all rotations.
[0082] The preparation of 10mg GL01 formulations with different solubilizing excipients and different processes were investigated. The formulations and processes are shown in Tables 3 and 4.
[0083] Table 3. 10mg GL01 formulations prepared using different solubilizing excipients and different processes 1-3
[0084]
[0085]
[0086] Table 4. 10mg GL01 formulations prepared using different solubilizing excipients and processes 4-6
[0087]
[0088] Dissolution studies were conducted on the formulation prepared according to the above prescription, and the results are as follows: Figure 1 and Figure 2 As shown in Tables 3 and 4 above, the leaching results indicate that the mixture of GL01, polyvinylpyrrolidone VA64, and polyethylene glycol 6000 exhibits significant leaching advantages after hot melt extrusion granulation. Therefore, further optimization studies on the hot melt extrusion process and its formulation are warranted.
[0089] In addition, although the typical crystal forms III and VI of GL01 API have relatively high equilibrium solubility in hydrochloric acid solutions at pH 1.0 and pH 2.0 after 48 hours (as shown in Table 1), the dissolution data of GL01 API directly into capsules show that the dissolution rate of GL01 is relatively low. In the dissolution test at 2-3 hours, it failed to dissolve completely.
[0090] 3. Determination of the formulation and process of solid dispersions
[0091] The compatibility results of the raw materials and excipients revealed that polyvinylpyrrolidone (VA64) and GL01 were stable under various conditions. This invention attempts to add a small amount of polyethylene glycol 6000 to the VA64 carrier to lower the glass transition temperature (Tg) of the solid dispersion, thereby reducing the hot melt extrusion temperature, as excessively high hot melt extrusion temperatures may lead to degradation of the active pharmaceutical ingredient. Comparing the effect of polyethylene glycol 6000 addition on the hot melt extrusion effect, the results showed that with increasing polyethylene glycol 6000 dosage, the extrudate gradually changed from clear and transparent to cloudy and opaque, eventually becoming an opaque waxy substance. The transparency of the extruded material was used as the criterion for determining whether a solid dispersion had been successfully formed.
[0092] The formulation ratio and process parameters of the hot melt extrusion process of GL01 were explored. The hot melt temperature, extruder torque, screw speed and extrudate transparency were used as process evaluation indicators. The solubilization effect of solid dispersion on GL01 during the dissolution process, the degradation of related substances and the risk of amorphous crystallization of GL01 were used as quality control evaluation indicators. The results are shown in Table 5.
[0093] Table 5. Exploration of Formulation Ratios and Process Parameters for Hot Melt Extrusion of GL01
[0094]
[0095]
[0096] The feasibility study of the process revealed the following:
[0097] (1) The feasible temperature range of the hot melt extrusion heating zone is 130℃~160℃. If the temperature is as low as 120℃, the extrudate will be opaque and the torque will be too large, and the equipment will not be able to operate normally. (2) When API and polyvinylpyrrolidone VA64 are prepared in a weight ratio of 1:5, 1:10, and 1:15, and an appropriate amount of polyethylene glycol 6000 is added, the material can be extruded. However, if polyethylene glycol 6000 is not added, a higher hot melt extrusion temperature is required, which may cause high-temperature thermal degradation of GL01. If polyethylene glycol 6000 is added in excess, the extrudate will be opaque. In YF6021009, the ratio of polyvinylpyrrolidone VA64 to polyethylene glycol 6000 is 10:1, and the extrudate is found to be not completely transparent. The final study found that the ratio of polyvinylpyrrolidone VA64 to polyethylene glycol 6000 is more suitable in the range of 20:1 to 30:1. (3) The feasible screw speed is 20~150rpm.
[0098] Evaluation of quality control indicators:
[0099] (1) Dissolution of extrudate after tableting:
[0100] API and polyvinylpyrrolidone VA64 were mixed at weight ratios of 1:5, 1:10, and 1:15, and then an appropriate amount of polyethylene glycol 6000 (batch numbers YF6021008, YF6021010, and YF6021007) was added. The successfully prepared GL01 solid dispersion was cooled and pulverized. Powder with a particle size of less than 35 mesh (500 μm) was weighed and mixed with the excipients according to the formulation in Table 6. Tablets were then prepared, and the results were used for dissolution curve comparison. Figure 3 As shown.
[0101] Table 6. Prescriptions for batches YF6021007, YF6021008, and YF6021010 of GL01 tablets.
[0102]
[0103]
[0104] Dissolution results showed that Formulation 10 (batch number YF6021010), with an API:VA64:PEG 6000 ratio of 1:10:0.5, had good dissolution ability. Formulation 7 (batch number YF6021007) may have had its dissolution affected due to excessively high amounts of VA64, which exhibited excessive viscosity during disintegration. Formulation 8 (batch number YF6021008) may have had its dissolution affected due to insufficient amounts of VA64, which was not enough to completely dissolve GL01.
[0105] (2) Study on the crystal transformation risk of amorphous active pharmaceutical ingredients in hot melt extruded solid dispersions:
[0106] GL01 formulation consists of an amorphous solid dispersion powder obtained through hot melt extrusion, cooling, and grinding, along with added silanized microcrystalline cellulose SMCC90, mannitol M100, crospovidone XL-10, and sodium stearate fumarate. In tablets, GL01 exists only in the solid dispersion powder. Therefore, studying the amorphous solid dispersion powder can effectively eliminate interference from added excipients and improve the sensitivity of detection.
[0107] Accelerated solid dispersion powder under humid and hot conditions, along with the supply of water molecules and external energy, increases the loosening of the copovidone polymer chains, thereby increasing the activity of the drug or excipient in the carrier system.
[0108] API and polyvinylpyrrolidone VA64 were mixed at weight ratios of 1:5, 1:10, and 1:15, and then an appropriate amount of polyethylene glycol 6000 (batch numbers YF6021008, YF6021010, and YF6021007) was added. The successfully prepared GL01 solid dispersion was cooled and then pulverized. The stability of the GL01 morphology in the solid dispersion was investigated under multiple accelerated conditions. The crystal form detection results of the solid dispersion under multiple accelerated conditions are shown below.
[0109] Among them, the XRPD results of the hot melt extrusion process on day 0 are as follows: Figure 4 As shown, the hot melt extruded products are all in an amorphous state.
[0110] In summary, using hot melt temperature, extruder torque, screw speed, and extrudate transparency as process evaluation indicators, and the solubilizing effect of solid dispersion on GL01 during the dissolution process, the degradation of related substances, and the risk of amorphous crystallization of GL01 as quality control evaluation indicators, the optimal formulation was determined to be GL01:polyvinylpyrrolidone VA64:polyethylene glycol 6000 in a weight ratio of 1:10:0.5, which can obtain hot melt extrudates with controllable quality and stable process.
[0111] 4. Confirmation of tablet formulation process
[0112] Based on the development of solid dispersion formulation process, the 10mg GL01 tablets were developed and determined using dissolution profile, related substances and stability as indicators. The optimized formulation composition is shown in Table 7.
[0113] Table 7. Composition of Unit Dosage Formula for 10mg GL01 Tablets
[0114]
[0115] Dissolution profiles of tablets (10mg tablets: batch YF6021015-10) prepared using the optimized formulation process were studied in various dissolution media. The results in different media are shown in Tables 8-11. These results indicate that the 10mg tablets dissolved more than 85% within 15 minutes in all four dissolution media under low rotation speed (50 rpm) without any surfactants, demonstrating good in vitro rapid dissolution performance.

[0126] 5. In vivo experimental study of the formulation and manufacturing process of the tablets in beagle dogs.
[0127] This study aimed to compare the effects of different dosage forms of GL01 administered orally to beagle dogs on pharmacokinetics, and the results are shown in Table 12. The experiment involved three beagle dogs, administered 0.5 mg / kg intravenously, 10 mg / tablet / dog orally, and 10 mg / capsule / dog orally, in a single-dose cycle of 7 days.
[0128] Table 12 Results of a comparative study of oral PO and IV administration of 10mg tablets and 10mg capsules in beagle dogs
[0129]
[0130]
[0131] The 10mg tablets (batch number YF6021015-10) are listed in Table 7 for the unit dose formulation of 10mg GL01 tablets; the GL01 capsules (batch number YF60JN001) formulation information is listed in Table 4 for 10mg GL01 preparations made with different solubilizing excipients and different processes.
[0132] The results above show that: (1) the average bioavailability of 10mg tablets is 60.3% and the average exposure is 6815hr*ng / mL, and the data have good parallelism. (2) In contrast, GL01 capsules have a lower average bioavailability of 13% and an average exposure of 1431hr*ng / mL, indicating that the absorption of the capsule formulation is significantly lower than that of the tablets. The bioavailability of 10mg capsules is only about 1 / 5 of that of 10mg tablets, which is significantly different (p<0.01). (3) GL01 is metabolized slowly in beagle dogs and has a longer half-life.
[0133] 6. Screening of dissolution conditions with differentiating strength for 10mg GL01 formulations.
[0134] In vivo studies in beagle dogs revealed that the bioavailability of 10mg capsules was only about 1 / 5 that of 10mg tablets. Dissolution behavior of GL01 tablets and capsules was investigated using two methods: pH 6.8 phosphate buffer and more stringent dissolution conditions (pH 1.0 followed by pH 6.8). The results are as follows... Figure 5 and Figure 6 As shown, the dissolution curves of 10mg GL01 tablets and capsules under pH 6.8 phosphate buffer conditions more accurately reflect the difference in bioavailability between the two in beagle dogs. Furthermore, at 30–45 min, the dissolution rate of 10mg GL01 tablets and capsules under pH 6.8 phosphate buffer conditions matched their bioavailability, and the dissolution rate of 10mg capsules was approximately 1 / 5 that of 10mg tablets.
[0135] In summary, the determined dissolution conditions are: pH 6.8 phosphate buffer, 50 rpm; the evaluation criterion is greater than 75% after 45 minutes.
