Definitions

  • the present invention relates to a new formulation comprising a high amount of at least one cannabinoid, wherein the cannabinoid is in a non-crystalline form.
  • Cannabinoids are several structural classes of compounds found in the cannabis plant primarily and most animal organisms or as synthetic compounds. At least 113 different cannabinoids have been isolated from the cannabis plant up to today.
  • cannabinoids and terpenoids present in a sample of cannabis, however only the main cannabinoids have been linked to pharmacological activity so far.
  • the main cannabinoid types are: cannabidiol (CBD), tetrahydrocannabinol (THC), cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicitran (CBT), cannabinodivarin (CBV), cannabiripsol (CBR), hexahydrocannabinol (HHC), delta-9-tetrahydrocannabiphoral (THCP), tetrahydrocannabivarin (THCV), endocannabinoid (anandamide) and endocannabinoid (2- AG).
  • CBD cannabidiol
  • THC cannabinol
  • CBN cannabinol
  • CBG cannabigerol
  • CBC cannabichromene
  • CBD cannabicitran
  • CBV cannabinodivarin
  • CBR cannabiripsol
  • HHC hex
  • Cannabinoids are known to have health benefits, which are shown in medical studies such as i.e., lowering blood pressure, reducing inflammation, preventing relapse in drug and alcohol addiction, treating anxiety disorders, treating gastrointestinal (Gl) disorders, and preventing seizures.
  • Cannabinoids can be administered in multiple ways, including by inhaling cannabis smoke or vapor, orally e.g., in the form of a tablet or capsule, and as an aerosol spray into the cheek.
  • Crystalline cannabinoids are found to have low oral bioavailability.

  • the particle size of the oil droplets containing the at least one cannabinoid should be small to assure a homogenous distribution such as in particular in the final dosage form.
  • This liquid formulation (emulsion/dispersion) can then be used as such or be transformed into a solid formulation (such as powder), wherein the at least one cannabinoid is contained in amounts of up to approximately 45 wt.-%, while being in a substantially non crystalline, i.e. , better bioavailable form.

Description

Cannabinoid Formulations
The present invention relates to a new formulation comprising a high amount of at least one cannabinoid, wherein the cannabinoid is in a non-crystalline form.
Cannabinoids are several structural classes of compounds found in the cannabis plant primarily and most animal organisms or as synthetic compounds. At least 113 different cannabinoids have been isolated from the cannabis plant up to today.
There are many different cannabinoids and terpenoids present in a sample of cannabis, however only the main cannabinoids have been linked to pharmacological activity so far.
The main cannabinoid types are: cannabidiol (CBD), tetrahydrocannabinol (THC), cannabinol (CBN), cannabigerol (CBG), cannabichromene (CBC), cannabicitran (CBT), cannabinodivarin (CBV), cannabiripsol (CBR), hexahydrocannabinol (HHC), delta-9-tetrahydrocannabiphoral (THCP), tetrahydrocannabivarin (THCV), endocannabinoid (anandamide) and endocannabinoid (2- AG).
Cannabinoids are known to have health benefits, which are shown in medical studies such as i.e., lowering blood pressure, reducing inflammation, preventing relapse in drug and alcohol addiction, treating anxiety disorders, treating gastrointestinal (Gl) disorders, and preventing seizures.
Cannabinoids can be administered in multiple ways, including by inhaling cannabis smoke or vapor, orally e.g., in the form of a tablet or capsule, and as an aerosol spray into the cheek. Crystalline cannabinoids are found to have low oral bioavailability. For instance, it is estimated that only 6% of an orally administered dose of crystalline cannabinoid was bioavailable under fasting conditions. On the other hand, lipid-dissolved cannabinoid has been reported to exhibit an approximately 4-fold increased bioavailability.
A problem in regard of formulating cannabinoids, particularly in high dosage forms, is the poor water solubility as well as the limited solubility of cannabinoids in various oils. This makes it challenging to provide liquid or solid dosage forms containing high amounts of one or more cannabinoids, in particular in non-crystalline form for improved bioavailability.
Therefore, the goal of the present invention was to provide a formulation, wherein at least one cannabinoid is formulated in a high amount, and wherein the at least one cannabinoid is (and remains upon storage) in a substantially non-crystalline form.
Furthermore, this formulation should be usable to produce further application forms (such as powders, tablets, capsules etc), which are also storage stable.
In addition, the particle size of the oil droplets containing the at least one cannabinoid should be small to assure a homogenous distribution such as in particular in the final dosage form.
Surprisingly it was found that when using a specific ratio of Vitamin E and at least one cannabinoid, stable emulsions with high amounts of at least one cannabinoid (in particular in a dissolved non-crystalline form) can be obtained.
This liquid formulation (emulsion/dispersion) can then be used as such or be transformed into a solid formulation (such as powder), wherein the at least one cannabinoid is contained in amounts of up to approximately 45 wt.-%, while being in a substantially non crystalline, i.e. , better bioavailable form.
Therefore, the present invention relates to a liquid formulation (LF) comprising
(i) 5 - 85 weight -% (wt-%), based on the total weight of the liquid formulation, of at least one cannabinoid, and

In all embodiments of the present invention the at least one cannabinoid is most advantageously in a substantially non-crystalline form, even more preferably dissolved in the Vitamin E.
In the context of the present invention, the term ‘crystalline’ is understood to mean a coherent or non-coherent part of one or more components with homogeneous physical properties, in particular a homogeneous melting range and a long-range order. It is well understood that crystals are solid, i.e. in a solid state of aggregation.
In the context of the present invention, the term ‘non-crystalline’ is understood to mean a cohesive or non-cohesive part of one or more components with homogeneous physical properties, in particular without any homogeneous melting range and long-range order.
In all embodiments of the present invention most advantageously, the non-crystalline cannabinoid is liquid, i.e. is present in a liquid (e.g. dissolved) state of aggregation, such as in particular dissolved in the Vitamin E. Even more preferably, the non-crystalline cannabinoid is not or not substantially amorphous but dissolved.
In the context of the present invention, the term ‘long range order’ is understood to mean a regular and periodic spacing of molecules or atoms (here of the at least one cannabinoid) in a crystalline solid. Accordingly, the exact position of a few molecules or atoms can advantageously be used to determine the position of all molecules or atoms in a crystalline solid.
The content of the crystalline form of the at least one cannabinoid in the liquid and the solid formulation according to the present invention can be measured using commonly known methods, such as differential scanning calorimetry (DSC).
In the context of the present invention DSC was used to determine the amount of crystalline form of the at least one cannabinoid in the liquid respectively solid formulation according to the present invention according to standard methods in the art, i.e. by using the respective crystalline cannabinoid as external standard.
Thus, the in all embodiments according to the present invention, preferably the degree of crystallinity (in %) is determined by DSC using the respective crystalline cannabinoid as external standard.
The DSC method as used in the present invention is carried out as follows:
Liquid or powder (solid) formulations (ca. 8-10 mg) were placed in aluminum pans and hermetically sealed. Empty pans were used as a reference samples. For the investigation of the cannabinoid bulk material (i.e. the respective crystalline cannabinoid), about 1-2 mg of sample was used (external standard). Each sample was heated from 10°C at 10 C/min to 90°C and then cooled down to 10°C at 10 C/min. Upon heating, for the crystalline cannabinoid compound the thermal transition peak is determined (observed), which for CBD was determined to be at ca. 68°C, which was attributed to the melting of the cannabidiol crystals. By analyzing the DSC thermograms and measuring the peak areas, the degree of crystallinity of a sample can then be determined, as the peak area of the DSC peak corresponds to the amount of heat released during crystallization/heat consumed during melting and is proportional to the degree of crystallinity of a sample. To determine the % of crystallinity, the peak areas of the samples are referenced against the peak area of the crystalline cannabinoid. The amount of crystalline cannabinoid present in the respective sample can then be calculated, which is then used to determine the degree of crystallinity (%), based on known total amount of cannabinoid present in the sample.

Examples
General methods
The degree of crystallinity of the solid formulations was measured using Differential Scanning Calorimetry (DSC) as outlined in the following:
External standard: Crystalline CBD (1-2 mg) was placed in an aluminum pan which was then hermetically sealed (external standard). An empty pan was used as reference. The respective samples were heated from 10°C at 10 C/min to 90°C and then cooled down to 10°C at 10 C/min. The crystalline CBD exhibited a thermal transition peak (melting point) at ca. 68°C.
The respective powder (solid) formulations were measured equally using ca. 8-10 mg of the respective sample. Then the peak area of the respective sample is referenced against the peak area of the external standard to calculate the amount of crystals respectively the percentage of crystallinity in the respective samples.
All particle sizes were determined using a Beckmann Coulter, Delsa Nano S (Dynamic light scattering).
The bioavailability was tested using a Caco-2 model as further detailed below.
Figure 1 : DSC thermogram of the solid formulation of example 2 (y-axis: heat flow (normalized) (W/g); x-axis Temperature (°C)) solid line: t=0 (directly after production) dashed line: after storage for 12 months at 5 °C dotted line: after storage for 12 months at 25°C dashed-dotted line: after storage for 12 months at 40°C.
The DSC analysis showed no crystallization peaks after storage even at low temperatures illustrating the excellent stability of the solid formulation according to the present invention.
Example 1
(i) For the preparation of the lipid phase, a total of 95 g of CBD was dispersed in 40.5 g of (all-rac)-a-tocopherol at 75° C under stirring until complete dissolution.
The lipid phase was kept warm until completing dispersion into the aqueous phase.
(ii) For the preparation of the aqueous phase, a total of 123 g pork gelatin, bloom 140, was hydrated and dissolved in 167.5 g warm water (40°C). Subsequently, 23.5 dried glucose syrup, DE2023 was added and the solution was heated to process temperature of 75°C.
(iii) The warm aqueous phase was stirred, and the warm lipid phase was slowly added and homogenized at an elevated temperature (ca. 75°C) to form a liquid formulation. No crystals were observed in the liquid formulation (visual assessment).
After viscosity adjustment with water (ca. 440 g), the emulsion was spray dried at ca. 180°C inlet temperature, 80°C outlet temperature using maltodextrin as carrier (approx. 6 %).
A fine flowing powder was obtained, containing ca. 2.5% residual water and 32.8 % CBD with >99% of the CBD in non-crystalline form as determined by DSC (i.e. no crystals detectable). Example 2
(i) For the preparation of the lipid phase, a total of 95 g of CBD was dispersed in 40.5 g of (all-rac)-a-tocopherol at 75° C under stirring until complete dissolution. Subsequently, 1.51 g of Vitamin E TPGS was added to the warm (75°C) CBD/(all-rac)-a-tocopherol mixture and homogenized.
The lipid phase was kept warm until completing dispersion into the aqueous phase.
(ii) For the preparation of the aqueous phase, a total of 123 g pork gelatine, bloom 140, was hydrated and dissolved in warm water (40°C). Subsequently, 31.5% dried glucose syrup, DE2023 was added and the solution was heated to process temperature of 75°C.
(iii) The warm aqueous phase was stirred, and the warm lipid phase was slowly added and homogenized for 40 min at elevated temperature of ca. 75°C to form a liquid formulation. No crystals were observed in the liquid formulation (visual assessment).
After viscosity adjustment with water, the emulsion was spray dried at ca. 180°C inlet temperature, 80°C outlet temperature using maltodextrin as carrier (approx. 6 %).
A fine flowing powder was obtained, containing ca. 2.5% residual water and 32.6 % CBD with >99% of the CBD in non-crystalline form as determined by DSC (i.e. below limit of detection (bld). The sample remained stable, i.e. showed no crystal formation even upon storage at various temperatures as determined by DSC measurements after 12 month storage at 5°C, 25°C and 40°C as outlined in Figure 1.
Table 1 below limit of detection As can be retrieved from table 1 , the addition of Vitamin E TPGS surprisingly decreased the particle size. In addition, no crystal formation was observed, neither in the liquid nor in the solid form. Example 3
A 40% CBD powder (solid) formulation was prepared in analogy to example 2 with the ingredients as outlined in Table 2. Again, no crystal formation was observed in the liquid formulation (visual assessment). The fine flowing powder obtained contained ca. 2.5% residual water and 40.7 % CBD with >99% of the CBD in non-crystalline form as determined by DSC. The solid powder remained stable open storage.
Table 2a below limit of detection Table 2b below limit of detection
Table 2c As can be retrieved from table 2b, increasing the amounts of Vitamin E TPGS to > 7 wt.-% results in an increase in the stickiness of the formulation, which is less desirable, as it impacts the handling properties.
As can be retrieved from table 2c, the increase in the ratio to 7:1 led to crystals formation compared to solid formulations having a ratio of 4:1 , which did not exhibit any crystal formation.
Example 4
CBD liquid and powder (solid) formulations using OSA starch instead of gelatine were prepared in analogy to example 1 with the ingredients as outlined in Table 3. Again, no crystal formation was observed in the liquid formulations (visual assessment). Table 3
As can be retrieved from Table 3, the use of OSA starch, in contrast to the use of gelatine, resulted in some crystal formation.
Example 4: Bioavailability
CBD powder (solid) formulations (beadlets) comprising approx. 12-16 wt.-% of CBD and a particle size distribution of approx. 200 nm using different oils as outlined below were prepared to compare the influence of the oil on the bioavailability of CBD. The liquid formulations were prepared in analogy to example 1 above. Afterwards the respective beadlets were prepared by spraying the liquid formulation into a fluidized bed using native corn starch. The amount of the respective oil was chosen such to assure full dissolution of the CBD in the oil. Table 4
The bioavailability was tested using Caco-2 Bioavailability assay as outlined below:
• Cell culture preparation
Caco-2 ECACC 86010202 (European Collection of Cell Cultures, Salisbury, UK) were cultured at 37 °C, in atmosphere of 5% CO2 in DM EM medium supplemented with 4.5 g/L D- Glucose, 4 mM L-Glutamine, 1 mM Sodium Pyruvate, 1 % MEM Non-Essential Amino Acids, 50 pg/mL Gentamicin (Life Technologies Europe B.V., Zug, Switzerland) and 10% heat- inactivated FBS (Sigma-Aldrich, Buchs, Switzerland). Sub-confluent cells were tryptinized using 0.25% Trypsin/EDTA (Life Technologies Europe B.V., Zug, Switzerland).
• Caco-2 Bioavailability assay
Cells were seeded at a density of 70,000 cells/well in 12-well celIQART® cell culture insert, PET membrane, 0.4 pM pore size, cell growth area 1.1 cm2/well (SABEU, Northeim, Germany). Media was changed every second to third day. After 21 days in culture, the barrier integrity of the differentiated cell monolayers grown on insert plates was confirmed by measuring transepithelial electrical resistance (TEER) using an EVOM2 Voltammeter (World Precision Instruments, Berlin) equipped with STX2-PLUS Electrodes. The TEER values correlate with the tightness of the confluent monolayer.
After 21 days the insert plates were washed 2 times with HBSS solution (HBSS pH 7.4 with Ca2+ and Mg2+, containing 5.5 mM D-(+)-glucose, Sodium Bicarbonate, and supplemented with 4 mM L-glutamine and 20 mM HEPES, Life Technologies Europe B.V., Zug, Switzerland) and incubated for 1 h at 37 °C in the CO2 incubator. The CBD treatment solutions were prepared in HBSS solution at a concentration of 15 pM. The tratment solution was applied on the apical chamber (200 pL) and 1.5 mL of 4% BSA in HBSS solution were added to the basolateral chamber. The plate was then incubated for 3 h at 37 °C in the CO2 incubator on an orbital shaker (80 rpm).
After incubation the buffer solutions from the basolateral (BL) and the apical (API) compartments were collected and diluted in acetonitrile for analysis. The cell layers (CL) were washed once with HBSS solution, then 500 pL acetonitrile were added to the apical part. The cells were scraped off from the membrane using a pipet tip, and then collected for analysis. Cannabidiol was quantitated by a stable isotope dilution LC-MS method using an Agilent 1290 Infinity II UHPLC connected to a Bruker Impact II Q-TOF mass spectrometer. Eight cannabidiol calibration solutions covering a concentration range of 2.5 ng/ml to 2000 ng/ml were prepared in acetonitrile. A 500 ng/ml solution of deuterium labelled d3-Cannabidiol (CAS No. 1435783-16-6) in acetonitrile served as internal standard. Before injection, 250 ml of calibration solution was mixed with 25 ml of internal standard. Likewise, 250 ml of the centrifuged CaCo2 compartment samples were combined with 25 ml internal standard. The analytical column was a Raptor ARC C18 column (2.1 x 150 mm). The mobile phase was water/acetonitrile 24:76 (v/v) containing 5 mM ammonium formate and 0.1 % v/v formic acid. The chromatogram was developed isocratically at a flow rate of 0.4 ml/min and a column temperature of 30°C. The injection volume was 1.5 ml. The column effluent was introduced into a VIP-HESI source (Bruker Daltonik GmbH) operating in positive ionization mode. The mass spectrometer was operating in full-scan mode scanning the range m/z 100-1000 with a spectrum rate of 4 Hz. Extracted high-resolution chromatograms at m/z 315.2319 and m/z 318.2507 with 5 mDa width were used for quantitation. A calibration curve was established by least squares regression by plotting peak area ratios (area analyte versus area internal standard) against added concentrations. Regression and computation of quantitative data was performed with TASQ 1 .4 software (Bruker Daltonik). The amounts of CBD measured as a percent of the original CBD content from the apical compartment (API), basolateral (BL) compartment, and the cell layer (CL) are shown in Table 5. Cell permeability (reflecting bioavailability) of CBD is determined by the sum of the amounts measured in the basolateral compartment and the cell layer (BL+CL). Higher recovery indicates higher cell permeability of CBD.
Table 5 Results bioavailability test
Total amount of CBD in API, BL and CL was set to 100%.
As can be retrieved from table 5, the product form with Vit. E exhibited the best bioavailability as the highest amount of CBD was detectable in the Cell lysate (CL) and Basolateral part (BL). Example 5: Pharmaceutical compositions comprising solid formulations according to the present invention
Tablets and capsules using the ingredients as outlined in table 6, 7 and 8 are prepared using the solid the solid formulations of examples 1 , 2, 3a, 3b, 3c, 4, 5 and 6, respectively according to standard methods in the art.
