Description

The thyroid hormones (THs) play a critical role in growth, development, metabolism, and homeostasis. They are produced by the thyroid gland as thyroxine (T4) and 3,5,3′-triiodo-L-thyronine (T3). T4 is the major secreted form in humans and is enzymatically deiodinated by deiodinases to the more active form, T3, in peripheral tissues. THs exert their action by interacting with thyroid hormone receptors (TRs), which belong to the nuclear hormone receptor superfamily, and regulate the transcription of target genes.


TRs are expressed in most tissues and exist as two isoforms (TRα and TRβ). Tissue distribution studies, mouse knockout studies, and evaluation of patients with resistance to thyroid hormone (RTH) syndrome have established that TRα is the predominant isoform in the heart and regulates most cardiac functions, while the TRβ isoform predominates in the liver and the pituitary and regulates cholesterol metabolism and thyroid stimulating hormone (TSH) production, respectively. In addition, TRβ agonists may be used for the treatment of adrenoleukodystrophy (ALD) and lipid disorders such as hypercholesterolemnia and fatty liver diseases, for example non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and glycogen storage disease (GSD). Some promising phosphonate TRβ agonists have been discovered; however, there exists a need for improved forms of such compounds to facilitate pharmaceutical development

Crystalline Form C


Some embodiments include an unsolvated crystalline form of Formula (I), referred to herein as crystalline Form C. The precise conditions for forming crystalline Form C may be empirically determined and it is only possible to give a number of methods which have been found to be suitable in practice.


Crystalline Form C was characterized using various techniques which are described in further detail in the experimental methods section. FIGS. 11, 12, 21-27 and 30 show the crystalline structure of Form C as determined by X-ray powder diffraction (XRPD). Crystalline Form C, which may be obtained by the methods disclosed above, exhibits prominent peaks at approximately 9.1°, 12.4°, 13.8°, 16.0°, 16.6°, 17.1°, 18.6°, 19.1°, 21.6°, 21.7°, and 23.7° two theta (2θ). Thus, in some embodiments, a crystalline form of the compounds of Formula I has at least one characteristic peak (e.g. one, two, three, four, five, six, seven, eight, nine, ten or eleven characteristic peaks) selected from approximately 9.1°, 12.4°, 13.8°, 16.0°, 16.6°, 17.1°, 18.6°, 19.1°, 21.6°, 21.7°, and 23.7° 2θ. In some embodiments, a crystalline form of the compounds of Formula I has at least three characteristic peaks selected from approximately 9.1°, 12.4°, 13.8°, 16.0°, 16.6°, 17.1°, 18.6°, 19.1°, 21.6°, 21.7°, and 23.7° 2θ.


As is well understood in the art, because of the experimental variability when X-ray diffraction patterns are measured on different instruments, the peak positions are assumed to be equal if the 2θ values agree to within a certain degree of variability. For example, the United States Pharmacopeia states that if the angular setting of the 10 strongest diffraction peaks agree to within ±0.2° with that of a reference material, and the relative intensities of the peaks do not vary by more than 20%, the identity is confirmed. Accordingly, in some embodiments, peak positions recited herein include variability within ±0.5° 2θ. In other embodiments, peak positions recited herein include variability within ±0.2° 2θ. As disclosed herein, the term “approximately” when referring to values of 2θ is defined as ±0.5° 2θ.



FIGS. 19a and 19b, and FIGS. 28a and 28b show results obtained by DSC for Crystalline Form C. These results indicate a peak at a temperature of about 122° C. for Crystalline Form C, which indicates the melting point for the crystal. Accordingly, in some embodiments, Crystalline Form C exhibits a melting point from about 117° C., to 127° C., from about 120° C. to about 124° C., or at about 122° C. Crystalline Form C was analysed by TGA, and in one instance exhibited a 1.3% weight loss and in another instance, exhibited <0.1% weight loss when carried out from 25° C. to 200° C.


Meanwhile, FIG. 29a shows dynamic vapor sorption (DVS) results for Crystalline Form C, and shows a water uptake of less than 0.2% by weight. XRPD results following DVA analysis, FIGS. 24 and 25, confirm that Form C did not transition to a different polymorph. FIG. 29b shows the phase equilibration experiment in water for 3 days, which showed no transformation of the crystalline Form C as seen by XRPD, FIG. 26.


Crystalline Form C can therefore be characterized as non-hygroscopic and stabile over a wide range of humidity. Crystal form C also shows good crystallinity, the content of residual solvents is very low (<0.1%), the melting point is relatively high (approx. 172° C.) and crystal form C does not show any evidence of hydrate formation. In contrast, the solvate forms tend to desolvate producing mixtures of the solvate and the amorphous form. Such advantageous and unexpected non-hygroscopicity and stability demonstrated by Crystalline Form C may be capitalized on. For example, methods of treatment and pharmaceutical compositions Crystalline Form C may provide long-term stability and low adsorption and desorption of water vapor, and may provide significant clinical improvements for the treatment of ALD and lipid disorders such as hypercholesterolemia and fatty liver diseases.

EXAMPLES AND EXPERIMENTAL METHODS

Additional embodiments are disclosed in further detail in the following examples, which are not in any way intended to limit the scope of the claims.


X-Ray Powder Diffraction (XRPD)


XRPD analysis was carried out on a Bruker D8 advance or a Philips PW 1710. In embodiments using the Bruker D8 device, samples were scanned using CuKa radiation, tube power of 35 kV/45 mA, a VANTEC1 detector, a step size of 0.017° 2θ, a time per step 105±5 sec time per step, and a scanning range of 2°-50° 2θ. Samples were also prepared as received or slightly crushed. Silicon single crystal sample holders were used, with sample diameters of 12 mm and depths of 0.1 mm.


In embodiments using the Philips PW device, samples were scanned using Copper Kα radiation, a step size of 0.02° 2θ, a 2.4 sec time per step, and a scanning range of 2°-50° 2θ. 0.1 mm sample holders were used. Samples were measured without any special treatment other than the application of slight pressure to get a flat surface. Measurements were performed at an ambient air atmosphere.


Thermogravimetric Analysis (TGA)


Thermogravimetric measurements were carried out with a Perkin-Elmer Thermobalance TGS-2 (aluminum sample pans, N2 atmosphere 50 ml/min., heating rate 10 K/min, range 25 to 200 or 350° C.).


Thermogravimetric Fourier-Transform Infrared Spectroscopy Analysis (TG-FTIR)


Thermogravimetric Fourier-Transform Infrared Spectroscopy measurements were carried out with a Netzsch Thermo-Microbalance TG 209 coupled to a Bruker FTIR Spectrometer Vector 22 (sample pans with a pinhole, N2 atmosphere, heating rate 10 K/min, range 25 to 250° C.).


Differential Scanning Calorimetry Analysis (DSC)


In some embodiments, DSC was carried out with a Perkin Elmer DSC7 with the following experimental conditions: 3.26 to 4.51 mg sample mass, closed gold sample pan, temperature range −50° C. to 100° C./150° C./225° C., heating rate 10 or 20 K/min. The samples were weighed in air.


In other embodiments, DSC was carried out with a Perkin Elmer DSC7 with the following experimental conditions: 3.53 mg sample mass, closed gold sample pan, temperature range −50° C. to 150° C., heating rate 20 K/min. The sample was weighed in air.



1H Nuclear Magnetic Resonance (NMR)


The samples were dissolved in CDCl3. The NMR spectra were recorded on a Bruker spectrometer (Ultrashield TM, B ACS 60, 300 MHz).


Karl Fischer Moisture Analysis


Karl Fischer moisture analyses were carried out according to standard procedures.


Dynamic Vapor Sorption (DVS)


The sample (9.869 mg) was placed on a Pt pan, and the sample was allowed to equilibrate at 25° C. at 50% relative humidity (r.h.) before starting a pre-defined humidity program. The predefined humidity programs include 1.0 hours 50%, from 50% r.h. to 0% r.h.; 5% r.h. per hour, 5 hours at 0% r.h., from 0% r.h. to 93% r.h.; 5% r.h. per hour, 5 hours at 93% r.h., from 93% r.h. to 50% r.h.; and 5% r.h. per hour, 1 hours at 50% r.h.


Solvents


Fluka or Merck grade solvents were used. Fluka no. 95305 deionized water for relevant experiments.


Measurement of the Approximate Solubility


In some embodiments, to determine the approximate solubility at room temperature, solvent was added in steps to the solid material. After every addition, the sample was well stirred. The addition of solvent was continued until complete dissolution or until 20 ml of solvent was added.


In other embodiments, aliquots of the test solvent were added to an accurately weighed amount of the compound of Formula I in small increments (usually 100-1000 μL), with sonication until complete dissolution was obtained, if possible. Dissolution was determined visually. The actual solubilities may be higher than reported due to slow dissolution rates or the use of excess solvent. The approximate solubility was determined in mg/mL to the nearest whole number.


Crystallization Experiments


Crystallization experiments were carried out with 40 mg to 256 mg of the compound. The solutions or slurries were stirred with a magnetic stirrer. The samples obtained after filtration (glass filter porosity P4) were air dried at ambient temperature and only for a short time to prevent possible desolvation of labile hydrates or solvates.


Starting Material A


Starting material was obtained from Metabasis Therapeutics Inc. The material was characterized as amorphous as confirmed by XRPD, FIG. 1.


The approximate solubility at ambient temperature must be known in order to carry out systematic crystallization experiments. The approximate solubility of the amorphous starting material A, at 23° C. are given in Table 1 below.

Example 1
Solution Based Crystallization Attempts

In the following Example, all evaporations and slurries gave oils. Slurrying the elevated temperature samples having tiny amounts of birefringent and extinctive solids in various solvents and antisolvents did not result in increased yield or size of the crystals. Stressing oils and the starting material under antisolvent vapor at elevated temperatures did result in tiny amounts of birefringent and extinctive solids embedded in oils and gels. Temperature cycling experiments showed no indication of crystallization. These results demonstrate the difficulty of crystallizing the compound of Formula I.


The details of various solution based crystallization experiments and results are given in Table 2 below.

Example 2
Non-Solvent Based Crystallization Attempts

The elevated temperature and humidity stress experiments resulted in oils containing small amounts of solids exhibiting birefringence and extinction. Sonication does not appear to offer any advantages over more common techniques. These results further confirm the difficulty of crystallizing the compound of Formula I. Heteroseeding using the diisopropyl ester analogue was also ineffective.

Example 3
Crystallization Experiments

Spontaneous crystallization of the compound of Formula (I) was observed when the amorphous form was dissolved at room temperature in a mixture of THF and heptane (ratio 75:25 v/v). Additional heptane was added until a turbid “solution” was obtained. This turbid “solution” was stirred with a magnetic stirrer at room temperature for 16 hours, yielding a white paste. The XRPD measurement confirmed crystalline material, FIG. 5 (Test 9 below). This first crystalline material was used to seed solutions or slurries of the amorphous form in a number of other solvent systems. In most cases crystalline material was produced within a short time at room temperature. Solvates were always produced using these crystallization conditions. The ethanol solvate (Test 8) and the THF solvate (Test 14) were checked by solution NMR (not shown).


The first attempt to desolvate the THF solvate at 80° C. in heptane (Test 15) resulted in a viscous sticky mass. After cooling to room temperature, the slurry was seeded with the ethanol solvate and stirred for 20 hours at room temperature. After filtration and air-drying at room temperature the sample contained only a very small amount of residual solvent and XRPD confirmed the production of a new crystal form (i.e., crystal form C), FIG. 9. Solution NMR spectrum (not shown) shows the same spectrum as for the starting material. This unsolvated crystal form C was used to seed further crystallization experiments.


Various crystallization experiments produced larger scale amounts of crystalline or solvate forms of the compound of Formula I. For example, the THF solvate (Test Result 20) and the unsolvated crystal form C (Test Results 21 and 23) were produced at a 200 mg scale.


The details of various crystallization experiments and results are given in Table 4 below.

Example 4
Characterization of Crystalline Samples

The crystalline solid forms were characterized by XRPD, TGA, DSC and selected samples by solution NMR.


The XRPD results of the unsolvated crystal form C, FIGS. 11, 12, 21-27 and 30, show good crystallinity, the content of residual solvents is very low (<0.1%) and the melting temperature is 122° C. (hermetically closed sample pans; DSC peak temperature) FIGS. 19a and 19b. Solution NMR shows the spectrum of the starting material (not shown).


The characterization of the solvates by DSC. FIGS. 13-18, provided an overview of the stability of the solvates as estimated by the temperature of peaks measured in hermetically closed sample pans. The temperature of the peaks of the solvates vary widely. The highest temperature observed was for the THF solvate (125° C.), FIG. 18, which reflects its high stability. For the ethanol solvate (66° C.), FIG. 15, and the EtOAc solvate (68° C.), FIG. 16, the temperature of the peaks are much lower and well below the boiling temperatures of the corresponding solvents. The ethanol solvate (Test Result 8) and the THF solvate (Test Result 14) were checked by solution NIR (not shown), and showed the spectra of the starting material and the solvent of the corresponding solvate.

Example 5
Additional Seeding Crystallization Experiments

Phase equilibration experiments in solvent mixtures at different temperatures and seeding experiments were used to search for other unsolvated crystal forms of the compound of Formula I. A number of typical crystallization techniques (e.g., recrystallization from the melt or crystallization by cooling solutions) were not applicable because under these conditions nucleation of the compound is hindered. In turn desolvation of the solvates tends to produce the amorphous form.


Seeding concentrated solutions of the amorphous form in ethanol and THF using the unsolvated crystal form C at room temperature produced the ethanol solvate (Test Result 26) and the THF solvate (Test Result 29), respectively. The characterization of different solvates by DSC provided an overview of the stability of the solvates as estimated by the peak temperatures measured in hermetically closed sample pans.


Crystal form C was directly produced under the conditions in Test 30: The amorphous form was dissolved in EtOAc and heated to 75° C. Heptane was added slowly until a ratio of 1:7 v/v EtOAc/heptane was reached. The system was seeded with crystal form C and stirred for an additional time at 77° C. The solid was isolated by hot filtration of the suspension. XRPD showed that unsolvated crystal form C was produced, FIG. 21.


For the crystallization of the unsolvated crystal form C, a solvent/antisolvent mixture which did not produce the corresponding solvate or an oil but still showed an acceptable solubility is desirable. In EtOAc/heptane mixtures at ratios below 1:7 v/v at 76° C. an oil was produced, even when seeding with crystal form C (Test Result 34).


The unsolvated crystal form C shows a high physical and chemical stability in EtOAc/heptane 1:7 v/v. Phase equilibration experiments for 3 days at room temperature and at 78° C. showed no transformation of the crystal form C from Test 37. Solution NMR showed the same spectrum as for the starting material (not shown).


Stirring a slurry of the amorphous form with seeds of crystal form C in EtOAc/heptane 1:7 v/v at room temperature for 18 hours also produced crystal form C (Test 42). However, at 2° C. the EtOAc solvate was formed (Test 43). The stability regions of the EtOAc solvate in solvent/antisolvent mixtures at different temperatures need to be tested. Crystal form C seems physically more stabile over a broader range of solvent/antisolvent ratios when using the EtOAc/heptane process than when using the ethanol/heptane process (Tests 33 and 34).


For a few samples the peak around 18° 2θ in XRPD was broader, as seen in Test 44 and Test 45, FIG. 23. Therefore a supersaturated solution was seeded (Test 47) with a sample which showed a relatively broad peak around 18° 2θ, FIG. 27. The solid produced in this stability experiment revealed that this broader peak does not indicate a physically more stabile form.


The details of the additional seeding crystallization experiments and results of the solid state of the samples of Example 5 are given in Table 6 below.

Example 6
THF Solvate Stability

Desolvation of the solvates tends to produce the amorphous form. Storing the THF solvate at 96% r.h. at room temperature for 8 weeks (Test 48) produced a mixture of the solvate and the amorphous form, as confirmed by XRPD, FIGS. 20a and 20b.

Example 7
Hydrate Formation

Crystal form C does not show any evidence of hydrate formation. DVS analysis at 25° C. showed a very low adsorption/desorption of water vapor when humidity was increased from 50 to 93% r.h. or reduced from 50% r.h. to 0% r.h. (approx. ±0.1%). After storing for 3 days at 96% r.h. at room temperature (Test 49), FIG. 29a, and at 40° C. (Test 50), XRPD showed no transformation of the crystal form. The water uptake measured by the Karl Fischer method was very low (<0.2%). In addition, a phase equilibration experiment in water for 3 days at room temperature showed no transformation of the crystal form (Test 51), FIG. 29b. The broad background in the XRPD diagram, FIG. 26, is due to water remaining in the sample after careful drying at room temperature following filtration of the suspension. The Karl Fischer result indicates 45% water content.

Example 8
X-Ray Powder Diffraction (XRPD) Measurements of Formula I

XRPD measurements of crystalline Form C of compound of Formula I were measured. Observed peaks are shown in FIG. 30 and Table 9. Prominent peaks are listed in Table 10. Note that none of the peaks are known to be representative or characteristic of this material since the state of preferred orientation in this sample is not known.


The range of data collected may be instrument dependent. Under most circumstances, peaks within the range of up to about 30° 2θ were selected. Rounding algorithms were used to round each peak to the nearest 0.01° 2θ, based on the instrument used to collect the data and/or the inherent peak resolution. The location of the peaks along the x-axis (° 2θ) in both the figures and the tables were determined using proprietary software and rounded to one or two significant figures after the decimal point based upon the above criteria. Peak position variabilities are given to within ±0.2° 2θ. For d-space listings, the wavelength used to calculate d-spacings was 1.5405929 Å, the Cu-Kα1 wavelength.
