Abstract
Description
[0001] This invention relates to solid pharmaceutical dosage forms for oral administration, comprising (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide (active ingredient (I)), characterized in that the active ingredient (I) exists in an amorphous form and is immediately released from a solid pharmaceutical dosage form for oral administration, and also relates to its preparation method, its use as a medicine, and its use for the treatment and / or prevention of diseases, particularly cardiovascular diseases, preferably thrombotic or thromboembolic diseases and edema and eye diseases.
[0002] Active ingredient (I), (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 2-Formamide, also known as 4-({(2S)-2-[4-{5-chloro-2-[4-(trifluoromethyl)-1H-1,2,3-triazol-1-yl]phenyl}-5-methoxy-2-oxopyridin-1(2H)-yl]butyryl}amino)-2-fluorobenzamide, is known from WO 2017 / 005725 and has the following formula:
[0003]
[0004] The active ingredient (I) is used as a factor XIa inhibitor and, due to its specific mechanism of action, can be used, after oral administration, to treat and / or prevent conditions, preferably thrombotic or thromboembolic conditions and / or thrombotic or thromboembolic complications, particularly cardiovascular conditions (including coronary artery disease, angina pectoris, myocardial infarction, or in-stent thrombosis), as well as cerebrovascular artery conditions and other conditions that lead to transient ischemic attacks (TIAs), ischemic stroke (including cardiogenic and non-cardiogenic strokes), and / or peripheral artery conditions that lead to peripheral artery disease (including peripheral artery occlusion, acute limb ischemia, amputation, interventional procedures such as angioplasty, stent implantation, or re-occlusion and restenosis after surgery and bypass surgery), and / or in-stent thrombosis.
[0005] To develop a solid drug dosage form for oral administration, the active ingredient (I), (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide, used in amorphous form.
[0006] For diseases requiring long-term treatment or for long-term disease prevention, it is desirable to maintain the lowest possible frequency of drug administration and the smallest possible tablet size. This is not only more convenient for patients but also improves treatment reliability by reducing the disadvantages of irregular dosing (improving adherence). To improve adherence, especially in elderly patients, tablets should be as small as possible, i.e., have a high concentration of the active ingredient, particularly regarding higher dose strength.
[0007] During the research and development process, it was discovered that the amorphous form of the active ingredient (I) has poor solubility in water. Oral administration of poorly soluble active ingredients often presents problems, resulting in insufficient bioavailability of the active ingredient (I). Oral solid dosage forms (e.g., tablets) should provide near-immediate release of almost all of the active ingredient (I) and offer adequate dissolution properties. Solid dosage forms should also possess the excellent characteristics of being able to be manufactured on an industrial scale to meet the needs of a large number of patients, while employing sustainable manufacturing methods.
[0008] Most solid drugs and dosage forms are prepared in a crystalline state, characterized by a regular, ordered lattice structure. These physical structures are generally thermodynamically stable and relatively easy to study using techniques such as differential scanning calorimetry and X-ray diffraction. Amorphous materials are thermodynamically unstable and readily revert to a crystalline form during storage. The mechanical properties and vapor adsorption characteristics of amorphous systems can differ significantly from those of crystalline materials, and amorphous drugs may be more chemically reactive. By definition, amorphous forms are metastable relative to crystalline materials, thus amorphous drugs readily revert to a crystalline form over time. Predicting the time range involved is obviously important but may be difficult to achieve. It has been shown that amorphous drugs may degrade faster than crystalline materials. [Craig et al., Thelevance of the amorphous state to pharmaceutical dosage forms: glassy drugs and freeze-dried systems. International Journal of Pharmaceutics 179(1999)179-207].
[0009] The problem related to the physical and chemical stability of amorphous drugs and systems is why amorphous methods are generally not adopted without stabilization measures.
[0010] In addition to creating lyophilized systems—in which the amorphous form of drugs (and excipients) can be stabilized—the creation of so-called amorphous solid dispersions (ASDs) is also well known as a stabilizing measure for original amorphous materials as well as formerly crystalline materials, and especially for oral dosage forms.
[0011] Even though these stabilized systems exhibit limitations in physical and chemical stability [Serajuddin published in: Solid Dispersion of Poorly Water-Soluble Drugs: Early Promises, Subsequent Problems, and Recent Breakthroughs. Journal of Pharmaceutical Sciences, Vol. 88, No. 10 (1999) 1058-1066], developing amorphous drug formulations remains a challenging and significant undertaking (e.g., bioavailability, physical stability, chemical stability, and preparation). The challenges are even greater when developing amorphous drugs and processing them via direct tableting.
[0012] Currently, only a few attempts have been made to develop stable oral dosage forms containing amorphous drugs prepared by direct compression.
[0013] Sun et al. loaded amorphous active pharmaceutical ingredients / drugs onto mesoporous silica. Thus, a robust formulation with good content uniformity, manufacturability, physical stability, and dissolution rate was obtained. [Sun et al. published in: International Journal of Pharmaceutics. 539(1-2)(2018) 184-189].
[0014] DE 10 2010 005 124 A1 describes a solid oral dosage form prepared by direct tableting, comprising amorphous lecanidipine and a hydrogel agent (i.e., hydroxypropyl methylcellulose) added as a stabilizing excipient.
[0015] WO 2009 / 138224 discloses a pharmaceutical composition comprising drosperinone in a substantially amorphous form and a carrier selected from hydroxypropyl methylcellulose (HPMC), polyvinylpyrrolidone (PVP), or microcrystalline cellulose (MCC), wherein the drosperinone and the carrier are present in a co-milled state. The amorphous form of the drug can be stabilized by co-milling different drosperinone and carrier particles to form a two-phase system.
[0016] WO 2022 / 189278 describes an amorphous solid dispersion (ASD) and a solid drug dosage form for oral administration, comprising (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide.
[0017] The most relevant techniques for preparing stable amorphous drugs (in so-called amorphous solid dispersions (ASDs)) are based on two main distinct methods: solvent evaporation and melting. Some mechanical methods, such as ball milling or grinding, can also induce a degree of amorphization. [Breitenbach, European Journal of Pharmaceutics and Biopharmaceutics 54 (2002) 107-117]. All these techniques share the commonality of being energy-intensive, costly, and / or posing ecological and hazard risks. Amorphous solid dispersions use specific carriers to amorphize and stabilize the drug in a solid state. Adding additional stabilizing excipients leads to increased tablet weight and size, which is known to negatively impact patient adherence. Furthermore, it is worth noting that amorphous materials in ASDs eventually revert to their crystalline form, albeit slowly. [Ma, Journal of Drug Delivery Science and Technology 50 (2019) 113-124]. Furthermore, when ASD is exposed to humid environments (e.g., stored under high humidity conditions), the presence of water significantly increases drug flowability and reduces the polymer's ability to inhibit recrystallization. Therefore, drug dosage forms containing ASD may require additional moisture-proofing measures, such as special coatings and / or the use of specialized product packaging materials that act as a moisture barrier or desiccant. For example, lopinavir and ritonavir are combined in fixed-dose tablets. Etravirin tablets are provided in a form coated with a polyvinyl alcohol polymer that protects the active ingredient from moisture, oxygen, and other environmental factors. It needs to be sold in bottled form, with each bottle containing three desiccant packets to keep the tablets dry.
[0018] Solid drug dosage forms prepared by tableting can optionally be rolled. Since many materials are not suitable for direct tableting, a granulation step is usually performed before tableting. Dry granulation of compacted materials after rolling is a common method for preparing granules besides wet granulation, and it is becoming increasingly important in the pharmaceutical industry. [Mosig published in: Powder Technology 266(2014)156-166].
[0019] This method is suitable for granulation of materials sensitive to moisture and heat. It is environmentally friendly, requires no solvent removal, and is easily scalable.
[0020] One major advantage is the continuous production of particles, which reduces costs.
[0021] However, compared with other granulation techniques, the resulting tablets have lower tensile strength. This is due to the limited binding potential, which is partially consumed in the first compression step. [Herting published in: International Journal of Pharmaceutics 338(2007)110-118].
[0022] Orally disintegrating tablets (ODTs) are a special type of tablet. They are attractive to many patient populations, such as the elderly who have difficulty swallowing these formulations, children, and patients with intellectual disabilities, uncooperative treatment, nausea, or those who need to restrict fluid intake / diet. Those who are traveling or have difficulty accessing water are also affected. To meet these medical needs, pharmaceutical engineers have developed a new oral dosage form called orally disintegrating tablets (ODTs), which typically disintegrate rapidly in saliva within seconds without the need for water. Drug dissolution and absorption, as well as clinical onset time and drug bioavailability, can be significantly higher than those observed with conventional dosage forms. [Hirani published in: Tropical Journal of Pharmaceutical Research, April 2009, 8(2), 161-172].
[0023] ODTs can be prepared using various methods, such as lyophilization, molding, and sublimation, using sugar filament systems or direct compression. Direct compression is convenient and cost-effective, but it is highly dependent on the active pharmaceutical ingredient (API) and the properties of the excipients used (e.g., flowability, compressibility, and compaction). Therefore, excipients with excellent compaction properties should be preferred. Excipients used in ODTs must be selected based on material properties (plastic, elastic, or brittle) and desired functions (e.g., well-defined particle size distribution, good flowability, enhanced compaction, or rapid disintegration). Mannitol is a commonly used excipient in fast-dissolving pharmaceutical formulations. However, when used as an untreated powder, poor flowability, cohesiveness, and insufficient compaction are limiting factors. Therefore, excipients co-processed with mannitol are an option. Co-processing refers to the interaction of two or more excipients at the subparticle level due to co-spray drying, co-spray agglomeration, or co-granulation, thereby improving functionality. [Published by Stoltenberg in: Eur. J. Pharm. Biopharm. 78 (2011) 662-669]. The co-processed mannitol used in this invention is sold under various trade names, for example... However, mannitol is known to induce amorphous drug crystallization even when stabilized in amorphous spray-dried dispersions. [Leane published in: Drug Dev Tech 18(2)(2013)359-366]. It has been shown in the literature that excipients such as mannitol can affect the polymorphic transformation during wet granulation, thus there is indeed a possibility that excipients can cause physical instability. Therefore, co-processed excipient systems containing mannitol (e.g., This can induce crystallization of amorphous drugs in drug formulations, especially when prepared without any stabilization measures.
[0024] Furthermore, literature indicates that tablet compression can cause phase separation, which is particularly important when it leads to the separation of the amorphous phase of amorphous drugs and ultimately instability, as described in [Ayenew published in: European Journal of Pharmaceutics and Biopharmaceutics 81(2012)207-213].
[0025] Some orally disintegrating formulations are hygroscopic and cannot maintain their physical integrity under normal temperature and humidity conditions. Therefore, they require moisture protection, which necessitates specialized product packaging. [Hirani, published in: Tropical Journal of Pharmaceutical Research, April 2009, 8(2), 161-172]. As mentioned above, hygroscopicity is a factor that increases the risk of amorphous drugs transforming into their crystalline form.
[0026] Therefore, the objective of this development project is to provide a solid drug dosage form for oral administration, comprising (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4-Formamide (active ingredient (I)), wherein the active ingredient (I) exists in an amorphous form, and this oral solid dosage form exhibits excellent dissolution properties and good bioavailability. The solid dosage form should also possess the excellent characteristic of being able to be prepared on an industrial scale. Furthermore, the amorphous form of the active ingredient (I) in the solid dosage form should be stable during long-term storage. Crystallization must be prevented under all circumstances, as crystallization of the active ingredient (I) leads to a decrease in dissolution rate and a reduction in the bioavailability of the active ingredient (I).
[0027] Surprisingly, a solid drug dosage form can be prepared without the use of water, organic solvents, or heating, in which the active ingredient (I) exists in an amorphous form and remains stable. This solid drug dosage form exhibits excellent dissolution properties and good bioavailability, as well as excellent tablet characteristics, thanks to its large-scale industrial preparation method, which can also be used for continuous preparation without individual batches if needed, while also being sustainable.
[0028] Surprisingly, in this invention, although it can be rolled, it still exhibits excellent tablet properties (including tablet hardness).
[0029] Surprisingly, the present invention describes a pharmaceutical dosage form prepared by a method not based on solvent evaporation or melting, wherein the amorphous drug contained therein is chemically and physically stable over a long period of time.
[0030] Surprisingly, the present invention describes a pharmaceutical dosage form provided as an orally disintegrating tablet (ODT) prepared by compression and containing mannitol, wherein the contained amorphous drug is chemically and physically stable over a long period of time.
[0031] Solid dosage forms for oral administration, comprising amorphous (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide (active ingredient (I)), characterized in that the dosage form is
[0032] A) Roll-pressed granules, which are obtained by rolling and grinding a mixture of amorphous active ingredient (I) and excipients, or
[0033] B) Immediate-release tablets, wherein a mixture of amorphous active ingredient (I) and excipients is rolled and ground together with the excipients to obtain rolled granules, which are then compressed into immediate-release tablets, or
[0034] C) Immediate-release tablets, which are based on the direct compression of a mixture of amorphous active ingredient (I) and excipients into tablets, or
[0035] D) Oral dispersible tablets containing an amorphous form of active ingredient (I) and excipients.
[0036] Solid dosage forms for oral administration, comprising amorphous (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide (active ingredient (I)), characterized in that the dosage form is
[0037] A) Roll-pressed granules, which are obtained by rolling and grinding a mixture of amorphous active ingredient (I) and excipients, or
[0038] B) Immediate-release tablets, wherein a mixture of amorphous active ingredient (I) and excipients is rolled and ground together with the excipients to obtain rolled granules, which are then compressed into immediate-release tablets, or
[0039] C) Immediate-release tablets, which are based on the direct compression of a mixture of amorphous active ingredient (I) and excipients into tablets, or
[0040] D) Oral dispersible tablets containing amorphous active ingredient (I) and excipients.
[0041] According to the release method of device 2 (paddle method) in the European Pharmacopoeia, at least 85% of the active ingredient (I) is released into the release medium after 30 minutes.
[0042] Solid drug dosage forms based on direct compression and their preparation methods are known.
[0043] The most common challenges in preparing solid drug dosage forms containing an amorphous active ingredient (I) are the required drug-to-excipient ratio to promote the desired release rate and bioavailability, and the selection of a suitable preparation method and scaling up to ensure the physical and chemical stability of the amorphous active ingredient (I) while enabling large-scale industrial production.
[0044] Furthermore, specific preparation methods that do not require the use of water, organic solvents, or heating can produce solid drug dosage forms for oral administration in the form of rolled granules or tablets (with good tablet hardness and low brittleness, enabling large-scale industrial tablet production), containing (4S)-2 4 -Chloro-4-ethyl-7 3 -Fluorine-3 5 -Methoxy-3 2 ,5-dioxo-1 4 -(trifluoromethyl)-3 2 H-6-aza-3(4,1)-pyridine-1(1)-[1,2,3]triazole-2(1,2),7(1)-dibenzoheptafen-7 4 -Formamide (active ingredient (I)). This solid dosage form is highly robust against changes in the preparation method during operation and technology transfer, and therefore the properties of this solid dosage form are not affected.
[0045] Surprisingly, it has been found that, according to the present invention, immediate-release tablets containing an amorphous form of active ingredient (I) prepared without the use of water or organic solvents or heating exhibit excellent dissolution properties and good bioavailability of active ingredient (I), as well as the excellent characteristics that allow for the industrial-scale preparation of solid drug dosage forms to meet the needs of a large number of patients, and that, if necessary, can be prepared continuously without separate batches, while using sustainable preparation methods.
[0046] This invention provides a method in which the active ingredient (I) is used in an amorphous form and mixed with other excipients. The mixture is then rolled. A disintegration accelerator may then be added and the mixture mixed again. Finally, a lubricant may be added and the mixture mixed again. The mixture can be used directly as granules or for preparing tablets. The tablets may optionally be coated.
[0047] The methods and excipients selected in this invention differ in some respects from those known to those skilled in the art and commonly used to prepare immediate-release tablets containing an amorphous active ingredient (I) without the use of water or organic solvents or heating.

[0100] b) Croscarmellose sodium as a disintegration promoter, and

[0102] Overall, the advantage of granulation by rolling is the improved flowability of the granules compared to the initial powder mixture. Literature indicates that tableting can cause stratification, which is particularly important when it leads to amorphous phase separation and ultimately instability of the amorphous drug form, as described by Ayenew (see above).
[0103] The advantage of this invention is that the mixture can be rolled without losing its excellent dissolution properties and good bioavailability of the active ingredient (I). Furthermore, tableting of the mixture reduces the risk of uneven distribution of the amorphous active ingredient (I) in solid drug dosage forms.
[0104] Surprisingly, the amorphous active ingredient (I) is long-term stable in rolled granules containing well-known standard excipients without the need for any stabilizers (e.g., polymers or gelling agents in the ASD matrix as described above).
[0105] To ensure excellent dissolution properties, the roller pressure [kN / cm] and gap [mm] must be strictly controlled during the rolling process. The roller pressure is preferably between 0.1 and 5.0 kN / cm, and the gap between 1.0 and 6.0 mm. Preferably, a smaller gap results in a lower roller pressure, and a larger gap results in a higher roller pressure. The most preferred roller pressure is 2 kN / cm and the gap is 3 mm.
[0106] Roll pressing is not a known method for stabilizing amorphous active ingredients. Therefore, surprisingly, roll pressing has been shown to be suitable for preparing solid drug dosage forms in which the amorphous active ingredient (I) is long-term stable.

[0125] Overall, the advantage of granulation by rolling is the improved flowability of the granules compared to the initial powder mixture. Literature indicates that tableting can cause stratification, which is particularly important when it leads to amorphous phase separation and ultimately instability of the amorphous drug form, as described by Ayenew (see above).
[0126] It is clear from the literature that rolling solid drug dosage forms often suffer from reduced final tablet hardness or slower dissolution performance. The advantage of this invention is that the mixture can be rolled without sacrificing its excellent dissolution performance, good bioavailability of the active ingredient (I), and excellent tableting characteristics. The resulting tablets exhibit excellent tablet hardness. Furthermore, the tableting of the mixture reduces the risk of uneven distribution of amorphous active ingredient (I) in solid drug dosage forms.
[0127] Surprisingly, the amorphous form of the active ingredient (I) is long-term stable in the roll-formed granule-based tablet. The tablet contains only well-known standard excipients and no stabilizers (e.g., polymers or gelling agents in the ASD matrix as described above).
[0128] To ensure excellent dissolution properties, the roller pressure [kN / cm] and gap [mm] must be strictly controlled during the rolling process. The roller pressure is preferably between 0.1 and 5.0 kN / cm, and the gap between 1.0 and 6.0 mm. Preferably, a smaller gap results in a lower roller pressure, and a larger gap results in a higher roller pressure. The most preferred roller pressure is 2 kN / cm and the gap is 3 mm.
[0129] Rolling itself is not a known method for stabilizing amorphous active ingredients. Therefore, surprisingly, it has been shown that it is possible to prepare tablets based on rolled particles in which the amorphous active ingredient (I) is long-term stable.

[0168] The drug dosage form of this invention is a tablet.
[0169] The drug dosage form of this invention is an immediate-release tablet.
[0170] The pharmaceutical dosage form of the present invention is a tablet, wherein a mixture of an amorphous active ingredient (I) and an excipient is rolled and ground together with the excipient to obtain rolled particles, which are then compressed into tablets, which are optionally coated, preferably coated.

[0178] Storage conditions used to evaluate stability include, for example, a closed container at 25°C / 60% relative humidity, a closed container at 30°C / 75% relative humidity, an open container at 25°C / 60% relative humidity, or an open container at 40°C / 75% relative humidity (pressure conditions).
[0179] Solid drug dosage forms containing active ingredient (I) exhibit surprisingly excellent stability even under pressure conditions (open storage at 40°C and 75% relative humidity for 6 months), allowing for non-protective packaging of drug dosage forms containing active ingredient (I) (e.g., blister packs or high-density polyethylene (HDPE) bottles without desiccants).

[0336] 8. Bioavailability, dissolution, disintegration and outcomes
[0337] 8.1 Bioavailability
[0338] To study bioavailability, a drug formulation containing the active ingredient (I) was administered orally to animals. Blood samples were collected from the test animals. Pharmacokinetic parameters, such as area under the curve (AUC) and maximum concentration (Cmax), were determined after oral administration. The corresponding pharmacokinetic parameters after oral administration were further calculated. The main pharmacokinetic parameters, clearance (CL) and volume of distribution (Vss), were calculated as follows:
[0339]
[0340] 8.2 Dissolution
[0341] Dissolution results comparable to the amorphous solid dispersion of Example 1 were demonstrated by using preparation techniques such as direct compression (Example 2) or dry granulation (Example 5) followed by tablet compression (Example 3). All examples released at least 85% of the active ingredient (I) into the release medium after 30 minutes. Furthermore, both techniques (Examples 2 and 3) significantly reduced disintegration time from 13 minutes in Example 1 to 2 minutes in Examples 2 and 3. To improve patient compliance and thus enhance clinical efficacy, the tablet size was significantly reduced from the 12x6m oval shape of Example 1 to the 7mm circular shape of Examples 2 and 3 to facilitate swallowing.
[0342] Example 4 illustrates a formulation of an orally dispersible tablet. For this example, dissolution results comparable to those of the amorphous solid dispersion in Example 1 are shown. Example 4 releases at least 85% of the active ingredient (I) into the release medium after 30 minutes. The advantage of this technique is that no liquid is required for tablet administration. The tablet disintegrates directly in the mouth in less than one minute, thus facilitating tablet swallowing and patient compliance.
[0343] The preparations in Examples 2, 3, 4, and 5 require no water, organic solvents, or heating, and the active ingredient (I) exists in an amorphous and stable form. This demonstrates that the preparation method is suitable for large-scale industrial production while also being environmentally sustainable. Assuming a currently projected annual demand of approximately 50 tons of active ingredient (I), eliminating the organic solvents would save approximately 300 tons of organic solvents annually. Therefore, the newly developed formulations in Examples 2 through 5 significantly improve the sustainability of the products, with the energy-saving, heat-free method also contributing to this improvement.
[0344] 8.3 Disintegration Method
[0345] According to the latest revision of the European Pharmacopoeia, 10th edition, Topic 01 / 2020, oral solid dosage forms are tested in a rigid basket apparatus. Six samples are placed in test tubes within the basket apparatus, and a disc is added. The apparatus uses water as the medium and is operated at 37±2°C.

[0347]
[0348] 9. Solubility
[0349] The solubility of the active ingredient (I) in both amorphous and crystalline forms in different solvents was determined. The results are shown in Table 2.
