Definitions
- the present invention relates to crystalline forms of 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one.
- the invention relates to two crystalline ansolvate / anhydrate forms of this compound, the polymorphs I and II.
- the present invention also relates to crystalline solvates, for example methanol and ethanol solvates of 11 ⁇ - (4-acetylphenyl) -20,20,21, 21, 21 -pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one as precursors for the preparation of these two polymorphs I and II.
- these drugs usually have to be in solid form.
- solid forms There are a number of solid forms possible. They can be amorphous or crystalline.
- the active ingredient is obtained as Ansolvat.
- a solvate forms by the incorporation of solvents in the crystal.
- a hydrate is, for example, a solvate which has been formed by incorporation of water into the crystal.
- a number of physicochemical properties are determined by the particular solid state shape. Such properties of pharmaceutical relevance are, for example, the chemical stability of the active ingredient, its stability to pharmaceutical excipients, its ability to be ground and its flow behavior. It is also known that crystalline solids have a higher stability compared to amorphous solids. In the case of amorphous solids, there is the risk of recrystallization and thus the risk of uncontrolled loss of the solid form used in the pharmaceutical formulation. The advantage of amorphous solids is, inter alia, their higher solubility or their significantly increased dissolution rate (dissolubility). tion).
- the preparation of solid pharmaceutical active ingredients includes, among others, chemical synthesis, purification and solids recovery.
- preparative chromatography is increasingly being used. It is able to deplete impurities to a high degree without causing a significant loss of active ingredient. This is particularly advantageous for chemically closely related to the drug contaminants that are depleted in the classical crystallization only poorly or with high losses of active ingredient in the mother liquor.
- the active ingredient is relatively diluted in the raffinate of the preparative chromatography stage. From this raffinate, the active ingredient must be isolated in solid form.
- 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one has heretofore been known only as an amorphous foam (US Pat. EP 0970103 B1, page 9, paragraph 0056).
- This amorphous foam is formed by concentration to Dry the fractions containing the active ingredient after chromatography.
- the amorphous foams obtained in this way do not meet the requirements for a pharmaceutical active substance with respect to the content of residual solvents.
- the separation of the foam from the agitator is difficult.
- Another step on the way to the final formulation is micronization. Micronization is a fine grinding of the ground material, for example with an air jet mill.
- DSC Differential Scanning Calorimetry
- XRPD X-Ray Powder Diffraction
- FIG. 2 shows the X-ray powder diffraction pattern of the amorphous foam, which shows no defined XRPD lines.
- Figure 4 shows the DSC curve of polymorph I, which melts at about 218 ° C.
- the infrared spectrum (single-bounce ATR IR) of polymorph I shows bands at 3416 cm -1, 1680 cm "1, 1628 cm -1 and 1215 cm" 1 (see Figure 5).
- the polymorph I thus found was also able to be produced on a larger scale (kg range).
- the methods used here are the displacement crystallization by means of water and the stirring.
- the polymorph I according to the invention has, in addition to the advantages mentioned above, a number of other properties which have a positive effect on the pharmaceutical processing. It does not charge electrostatically and can therefore be easily micronized in the air jet mill.
- Figure 6 shows a typical distribution curve of the ground material. A particle size distribution in which more than 50% of all particles have a diameter of less than or equal to 3 ⁇ m (for the lower distribution, measured by the volume-related particle size distribution). sitting (so-called x 50 , 3 value) can be for the amorphous material very poorly and in particular not achieve on an industrial scale, since the e- electrostatic charge and the associated poor flowability extremely difficult targeted metering in the mill.
- polymorph I In the micronization of polymorph I according to the invention, the proportion of residual solvent decreases further.
- the corresponding values can be found in Table 1.
- the residual solvent content of polymorph I after micronization is 0.34-0.35% below the recommended value for ethanol in the ICH Q3C guideline (CPMP / ICH / 283/95, 4.3, page 8/18) of 0, 5%.
- polymorph I According to the X-ray powder diffraction gram, polymorph I is present before and after micronization without any proportion of ethanol solvate.
- the polymorph I has superior stability over the amorphous form. This is shown when comparing the results of the temperature, humidity and especially light load tests. Table 2 shows the decrease in the active ingredient content under storage at elevated temperature and elevated humidity. Before storage, the material used had a content of 98.4% and 95.4%, respectively.
- Tab. 2 Comparison of the short-term stability of amorphous 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-diene-3 on and of polymorph I during storage at elevated temperature and elevated air humidity. Indicated is the decrease of the drug content.
- Table 3 shows the stabilities after storage below 20 kLux for 42 hours and for 66 hours. The starting values were 98.4% and 95.4% respectively.
- Table 4 shows the increase in epoxy contamination upon storage of amorphous 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4.9 -dien-3-one under stress conditions or under light.
- the polymorph I according to the invention has an increase of these impurities of less than 0.2%.
- Tab. 4 Increase in epoxy contamination upon storage of amorphous 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9- dien-3-one and polymorph I when stored under light.
- Partial recrystallization to polymorph I was found under stress conditions (15 d, 90 ° C / 75% relative humidity) for the amorphous active substance. It is believed that such recrystallization also occurs when the amorphous phase is stored at lower temperatures for an extended period of time. However, such a conversion is unavoidable in the finished dosage form. wishes, as this may lead to an altered, not reproducible release of the drug, but also the hardness of the dosage form may be affected.
- the polymorph I according to the invention can be processed into pharmaceutical preparations which can be used for the treatment of myomas or a mammary carcinoma. It can be used as an active ingredient in female contraception, but also for the treatment of gynecological disorders, such as dysmenorrhea or endometriosis, hormone replacement therapy, menstruation and induction of labor. Because of its strong antitumor activity, it can also be used in combination with an antiestrogen (simultaneously or sequentially) in preparations for the treatment of hormone-dependent tumors (EP0310542). Also conceivable is a use in the treatment of tumors in the intestinal area, in the area of the prostate, of the ovary, of the endometrium and of meningomas.
- the polymorph I according to the invention can be obtained from an organic solvent by displacement crystallization.
- 11 ⁇ - (4-acetylphenyl) -20,20,21, 21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one may be used with the anti-displacement agent.
- Solvent do not form a solvate. It is also possible to use as primary solvents those with which 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-diene-3 - On a solvate forms, but then the proportion of primary solvent in the displacement must be reduced so far that the solvate is unstable.
- One possible anti-solvent is water, since 11 ⁇ - (4-acetylphenyl) -20, 20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one does not form hydrates.
- the amount of water required to prevent the formation of the solvate depends both on the primary solvent and on the temperature at which the crystallization is conducted.
- Table 5 lists the proportions of water in ethanol required for the primary solvent ethanol as a function of temperature which are at least required for safe crystallization of polymorph I from ethanol. At room temperature temperature (20 0 C) are, for example, 40% water wt- required. 40 wt% means 40 weight percent water, so per gram of solvent mixture 0.4 g of water are included.
- the solubility of 11 ⁇ - (4-acetylphenyl) -20,20,21, 21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one in a water-ethanol Mixture has a strong dependence on the water content. This dependency is shown in Figure 7.
- the solubility of 11 ⁇ - (4-acetylphenyl) -20,20,21, 21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one is at a level of 20% by weight of water has already fallen to one-hundredth of the solubility in pure ethanol.
- the polymorph I according to the invention can also be obtained by stirring. It is known that when stirring in a solvent with low solvency phase conversions between different Festköperformen are possible. The conversion always leads to the more stable under the specific conditions solid. Stirring solvates may result in removal of the solvation solvent. For this, the stability domain for the solvate must be left. As described above, 40 wt% of water in ethanol is sufficient at room temperature. The solubility of 11 ⁇ - (4-acetylphenyl) -20,20,21,21,21-pentafluoro-17-hydroxy-19-nor-17 ⁇ -pregna-4,9-dien-3-one is in such a mixture already sufficiently low, compare Figure 7, so that the process can be performed without much subtlety loss. Whether the new phase resulting from such agitation is amorphous or crystalline, the can not be predicted oretically. According to the invention results in the described Ausrlickung the polymorph I.
- Figure 10 shows the X-ray powder of polymorph Il (Cu K ⁇ rStrahlung, 20 - 25 ° C).
- Other XRPD lines are 7.1 ⁇ and 5.6 ⁇ .
- Figure 11 shows the DSC curve of polymorph II, which melts at about 135 ° C.
- the melt of polymorph II recrystallizes as polymorph I, which melts at about 218 C C.
- the infrared spectrum (single-bounce ATR-IR) of Polymorph II shows bands at 3653 cm “1 , 1682 cm “ 1 '1601 cm “1 and 1209 cm “ 1 (see Figure 12).
- thermogram shows a recrystallization exotherm followed by a melting endotherm with an onset temperature of 218 ° C (see Figure 1).
- ethanol solvate 1000 mg are suspended in 5 mL of methyl ethyl ketone (MEK). It is stirred for 30 minutes at 90 ° C; then cooled to -15 ° C within 60 minutes and stirred at this temperature for 60 minutes. The suspension is added to a -15 ° C cold filter and filtered with suction. To increase the yield, the reaction vessel with 1 mL of methyl ethyl ketone is from - 15 0 C and purged the Spülsuspension also added to the filter.
- MEK methyl ethyl ketone
