In the following examples, the abbreviations have the meanings provided in the table below.
Certain densities are provided below where the vehicle for each is 65:20:15 Labrafac WL 1349, Lauroglycol 90, Tween 80:
Densities were measured using procedures known to those of ordinary skill in the art.
Different solubilizers were screened for the formulation of Compound 1. Table 1 showed screening of excipients for the formulation of Compound 1. Compounds of Entries 6, 9, 11, 15, and 16 at both concentrations were soluble. Compounds of Entries 7 (200 mg/mL dilution), 8 (200 mg/mL dilution), and 17 (400 mg/mL dilution) were initially soluble but crashed out later (after overnight). Compounds of entries 1-5, 10, and 12-14, were not soluble. Gelucire 44/14 and Labrafac Lipo WL1349 seemed promising as solubilizers for Compound 1, and thus further experimentation were conducted with them (Entries 16 and 11 respectively). Although, caproyl also looked promising, it was found to be toxic in monkeys and thus, not pursued.
Based on the initial screening as shown in Table 1 and based on limits of excipients allowed by FDA, the solubility of Compound 1 in the oils in Table 1A were measured. Based on the solubility data, Labrafac WL 1349 was further pursued.
Certain combinations of Gelucire 44/14 with Solutol HS15, TPGS and Tween 80 were screened as shown in Table 2 at 200 mg/g concentration of Compound 1. Physical stability was observed microscopically at week one at 25° C./60% RH and at 5° C. Bioperformance was assessed visual observation after 10× dilution in FaSSIF. Based on the crash resistance test performed with ten times dilution with FaSSIF, the most promising formulation combination for Gelucire 44/14 appeared to be 80% w/w Gelucire 44/14, 10% w/w TPGS and 10% w/w Tween 80.
In the above table and in this paragraph, the % w/w are based on the total weight of the vehicle without compound. The 80% w/w Gelucire 44/14, 10% w/w TPGS and 10% w/w Tween 80 formulation vehicles were further tested at lower Compound 1 concentrations of 150 mg/g (i.e. 150 mg of Compound 1 in 1 g of Compound 1+vehicle) and 100 mg/g (i.e. 100 mg of Compound 1 in 1 g of Compound 1+vehicle) to minimize the crystallization risk upon storage. Physical stability was observed microscopically at week one at 25° C./60% RH and at 5° C. Bioperformance was assessed visual observation after 10× dilution in FaSSIF. As shown in Table 3, crystallization is observed after 1 h and 1.5 hour for Compound 1 concentrations of 150 mg/g (i.e. 150 mg of Compound 1 in 1 g of Compound 1+vehicle) and 100 mg/g (i.e. 100 mg of Compound 1 in 1 g of Compound 1+vehicle), respectively.
In the above table, the % w/w are based on the total weight of the vehicle without compound.
To develop a SEDDS formulation of Compound 1, the combinations of Labrafac WL 1349 with co-surfactant Lauroglycol 90 (low HLB value) and surfactant Tween 80 (High HLB value) were tested to form a SEDDS formulation (Table 4).
In the above table, the % w/w are based on the total weight of the vehicle without compound. Formulation A formed a clear single phase solution vehicle whereas Formulation B did not form a single phase with Tween 80 forming a separate phase.
Formulation A was further evaluated as potential SEDDS formulation of Compound 1.
The Gelucire 44/14 formulation in Table 5 was prepared by melting at 45° C. and mixing the required quantities of TPGS (melted at 37° C.) and Tween 80 at RT to form a clear solution vehicle at 45° C. Compound 1 was then solubilized by mixing at 45° C. to form a clear solution.
The Labrafac-based formulation in Table 5 was prepared by mixing Labrafac WL 1349 with Lauroglycol 90 and Tween 80 at RT to form a clear solution vehicle. Compound 1 was then solubilized by mixing advantageously at RT to form a clear solution. In the table below, the % w/w are based on the total weight of the vehicle without compound.
Two formulations selected for Gelucire 44/14-based and Labrafac-WL-1349-based formulation vehicles with Compound 1 at 100 mg/g (i.e. 100 mg of Compound 1 in 1 g of Compound 1+vehicle) are shown and compared in Table 5. The Gelucire 44/14-based formulation is a semi-solid at RT, while the Labrafac-WL-1349-based formulation is advantageously a liquid at RT. The Gelucire 44/14-based formulation, when diluted to 10 times with FaSSIF, forms a clear solution. However, Compound 1 precipitation is observed after about 1.5 hour. The Labrafac-WL-1349-based formulation forms an oil-in-water emulsion when diluted to 10 times with water, and Compound 1 is crash-resistant for at least about 24 hours, being predominantly solubilized in the oil phase.
Physical stability evaluation of both Gelucire 44/14-based and Labrafac-WL-1349-based formulation vehicles was done under polarized microscope. The Gelucire 44/14-based formulation as shown in
The chemical stability evaluation were also performed. Both Gelucire 44/14-based and Labrafac-WL-1349-based formulations are chemically stable at 25° C./60% RH and 40° C./75% RH at one month with less than 0.05 percentage points of degradation observed in either formulations as shown in Table 6 and 7 respectively.
Based on the solubility, and physical stability data, the Labrafac-WL-1349-based formulation was further pursued, and discussed herein.
In the above table, 1M means 1 month.
In the above table, 1M means 1 month.
A sesame oil formulation was prepared by mixing 100 mg Compound 1 per g of Compound 1 and sesame oil.
The physical and chemical stability of Vehicle C Labrafac-WL-1349-based formulation of Compound 1 at 100 mg/g and sesame oil-based formulation were performed.
Both formulations were physically stable for up to 3 months at 25° C./60% RH and 40° C./75% RH conditions with no birefringent crystals observed under polarized microscope (data not shown).
As shown in Table 8, the formulation was relatively stable with total impurity levels increasing only from 0.31% at initial to 0.38% at three months at 40° C./75% RH. Table 10 showed the formulation vehicle used.
In the above table, 1M, 3M, and 6M means 1 month, 3 months and 6 months respectively.
In the above table, 1M and 3M means 1 month and 3 months respectively.
The Allowable Daily Intake (ADI) values for each of the excipients or components of the Labrafac-WL-1349-based Formulation C-1 is shown in Table 9. At the maximum possible clinical dose of 1000 mg/day of Compound 1, the ADI limit for Vehicle C is exceeded for Tween 80 (1800 mg vs. 1500 mg ADI limit). Labrafac WL 1349 and Lauroglycol 90 levels are well within the limit at this highest dose level. The Tween 80 level was reduced from 20% w/w to 15% w/w in the vehicle (Vehicle D) to keep within the ADI limits. The composition of an optimized Vehicle D is Labrafac WL 1349 65% w/w, Lauroglycol 90 20% w/w and Tween 80 15% w/w. This vehicle still forms a clear single-phase solution at RT.
(a)The ADI is calculated based on NOAEL of 9 g/kg from 47 weeks study in Wister rats using procedures disclosed in Food Chem Toxicol. 2000, 38(1), 79-98.
(b)The ADI is 500 mg/kg per day for adult patients and children >5 years and 50 mg/kg for children <5 years and >1 month.
The IIG values in Table 10 are the limits of the excipients on the FDA website.
The actual compositions of Compound 1 (at 100 mg/g concentration, i.e. 100 mg of Compound 1 in 1 g of Compound 1+vehicle) with 18% Tween 80 (60:20:20 Labrafac-WL -1349:Lauroglycol 90:Tween 80) (Formulation C-1) and 13.5% Tween 80 (65:20:15 Labrafac-WL-1349:Lauroglycol 90:Tween 80) (Formulation D-1) are shown in Table 10 and Table 11, respectively.
The actual compositions of Compound 1 (at 60 mg/mL concentration) with 14.07% Tween 80 (65:20:15 Labrafac-WL-1349:Lauroglycol 90:Tween 80) (Formulation E-1) and Compound 1 (at 100 mg/mL concentration) with 13.44% Tween 80 (65:20:15 Labrafac-WL -1349:Lauroglycol 90:Tween 80) (Formulation F-1) are shown in Table 12 and Table 13, respectively.
The physical and chemical stability of 50 mg strength capsules of Formulation D-1 (100 mg/g concentration in Vehicle D, i.e. 100 mg of Compound 1 in 1 g of Compound 1 + Vehicle D) was assessed at accelerated conditions of temperature and humidity. The physical and chemical stability of 60 mg strength capsules of Compound 1 Formulation D-2 (120 mg/g concentration in Vehicle D, i.e. 100 mg of Compound 1 in 1 g of Compound 1+Vehicle D) was also assessed at accelerated conditions of temperature and humidity. Size 00 Hard Gelatin Capsules of Swedish orange color were used for the study.
Both strengths are physically stable for up to one month at 5° C., 25° C./60% RH and 40° C./75% RH conditions with no birefringent crystals observed under polarized microscope (data not shown).
The chemical stability of 50 mg and 60 mg strength capsules of Compound 1 Labrafac-based Formulations D-1 and D-2, respectively, analyzed by HPLC, is shown in Table 14 and Table 15, respectively. About 2% or less change in potency from initial to a duration of time of at least one month at 5° C., 25° C./60% RH and 40° C./75% RH for both strengths were observed. Also, about 1 percentage point or less degradation was observed from initial to all conditions tested for both strengths.
The chemical stability of 60 mg/mL and 100 mg/mL strengths of Compound 1 Labrafac-WL-1349-based Formulations E-1 and F-1, respectively, analyzed by HPLC, is shown in Table 16 and Table 17, respectively. No change in potency was detected from initial measurement to a measurement at two weeks or at one month, for each of the two test conditions (25° C./60% RH and 40° C./75% RH. In addition, no degradation was observed from initial to all conditions tested for both solutions.
A monkey PK study was conducted with a sesame oil formulation of 100 mg/g of Compound 1, a Gelucire 44/14-based formulation of 100 mg/g Compound 1 (Gelucire Form 1), and two different Labrafac-WL-1349-based formulations of 100 mg/g Compound 1. In this paragraph, 100 mg/g is 100 mg of Compound 1 in 1 g of Compound 1+vehicle. The formulations were administered with Low-fat Food for Testing and Medium-fat Food for Testing and Labrafac-WL-1349-based formulation of Compound 1 administered with Low-fat Food for Testing at dose of 125 mg, PO (Table 18). Each of the formulations in Table 18 were administered as 4 capsules/dose. In the table below, the % w/w are based on the total weight of the vehicle without compound. Four monkeys per cohort were used.
As shown in Table 19, bioavailability appears to be superior for Gelucire 44/14-based formulation (60.0%). Bioavailability of Labrafac-based formulation P1G2 (49.1%) is comparable to sesame oil-based formulation P1G1 (˜40.8%) with Labrafac formulation P1G2 having slightly higher exposure at 49.1%. Another observation is the absence of a second peak in the PK profiles of Gelucire 44/14-based and Labrafac-based formulations of Compound 1 compared to sesame oil-based formulation. This second peak in the sesame oil formulation indicates an unknown absorption phenomenon.
Also as shown in Table 19, better mitigation of observed positive food effect (i.e. a smaller difference in bioavailability between an administration with Low-fat Food for Testing and an administration with Medium-fat Food for Testing) is best with Labrafac-WL-1349-based formulation with Vehicle D (where the vehicle alone contains 15 wt/wt % Tween 80) compared to Labrafac-WL-1349-based formulation with Vehicle C (where the vehicle alone contains 20 wt/wt % Tween 80). With a low-fat meal, the Labrafac-WL-1349-based formulation with Vehicle D (where the vehicle alone contains 15 wt/wt % Tween 80) has a comparable bioavailability to Labrafac-WL-1349-based formulation with Vehicle C (where the vehicle alone contains 20 wt/wt % Tween 80). However, with Medium Fat Food for Testing, a formulation using Vehicle D has a lower bioavailability of 29.4% compared to 49.1% bioavailability obtained with a formulation using Vehicle C. Thus, the lesser difference in bioavailability between Low Fat Food for Testing and Medium Fat Food for Testing for Vehicle D (15% Tween 80) when compared to Vehicle C (20% Tween 80) is surprising. This means that a formulation of Compound 1 in Vehicle D could be administered advantageously with or without food. In the table below, the wt/wt % refers to the amount of Tween in the vehicle (without compound).
A total of 36 different excipients including pharmaceutically acceptable oils, surfactants and co-surfactants were evaluated for Compound 1. Solubility is as shown in Table 20. Higher solubility of Compound 1 in oils is desirable to increase drug loading.
As shown in Table 20, the SEDDS formulation can be achieved with a range of pharmaceutically acceptable oils. However, the choice of surfactant and co-surfactant may be limited due to several reasons: (a) some commercially available surfactants are non-GMP in nature and hence cannot be used for humans, (b) semi-solid physical state of some of the excipients makes them inappropriate for oral solution formulation, and/or (c) phase miscibility issues with some surfactants causing physical instability including drug precipitation. In order to achieve an optimized SEDDS formulation of a combination of oil, surfactant, and co-surfactant. Several formulation design related aspects are considered, for example: safe amount for daily intake for excipients, drug solubility in SEDDS formulations, crash resistance/drug precipitation, physical and chemical stability, bioperformance, and pharmacokinetics. Based on these aforementioned criteria, two co-surfactants (Lauroglycol 90 and Capryol 90) and a surfactant (Tween 80) were selected to prepare additional SEDDS formulations. Sesame oil only formulation exhibited a second peak as shown in
A total of 15 SEDDS formulations were screened for the phase clarity and solubility studies as shown in Table 21. In the table below, the % w/w are based on the total weight of the vehicle without compound. Most of the SEDDS formulations (e.g., olive-oil based, Labrafac-WL -1349-based etc.) were clear and provided high drug solubility. Highest solubility of Compound 1 was observed with Labrafac PG and Labrafac WL 1349 based formulations. The SEDDS formulations that exhibited hazy or had significantly lower drug solubility were omitted from further screening. Hence, a total of 6 formulations (Table 21, Prototype # 4, 6, 10, 12, 14, and 15) were selected for a monkey PK study.
The six formulations from Table 21 that exhibited phase clarity and good to excellent solubility for Compound 1 were evaluated in monkey PK studies as shown in Table 22. In the table below, the % w/w are based on the total weight of the vehicle and compound. All six formulations were crash resistant. Maisine CC based formulations from Table 21 were not further evaluated due to relatively lower solubility of Compound 1 in these formulations. Caproyl based co-surfactant formulations were eliminated due to toxicity issues found with the excipient.
Three monkeys per group were evaluated and dosed with 50 mg/kg of Compound 1, in the respective formulations. The monkeys were fed 30 minutes prior to dosing with a medium fat liquid diet, 5 mL/kg containing 0.23 g/mL of total fat. Monkey PK study results are shown in
The Labrafac WL 1349-based formulation showed the lowest PK variability and the desired plasma levels with minimal peak-to-trough ratio (difference between Cmax and Ctrough), Table 23. The peak (bump) in the elimination phase observed with the sesame oil-only formulation and Formulation 4 was not observed with Formulations 1-3 and, 5, and 6.
Certain formulation provided herein were tested for stability, as provided herein, and demonstrated good stability under various conditions. Other formulations, such as Formulations 1-5, provided herein, have not been tested for stability but would be expected to demonstrate comparable stability to those that were tested.
In certain embodiments, 20 wt/wt % Lauroglycol (wt/wt % based on total weight of vehicle) may advantageously assist in maintaining a one phase solution.
One advantage for Formulation 6 compared to a formulation of Compound 1 in sesame oil only is that Formula 6, with 10% w/w and 12% w/w Compound 1, are stable at RT, where the maximum advisable loading of Compound 1 in sesame oil only is 10% w/w. In addition, while the formulation of Compound 1 in sesame oil only demonstrated good chemical stability at RT, Formulation 6 demonstrated somewhat better chemical stability at accelerated conditions and for a longer term. Still another advantage of Formulation 6 compared to the formulation of Compound 1 in sesame oil only relates to micellization and solubilization in gastrointestinal fluids; Formulation 6 is designed to self-emulsify where sesame oil only formulation must rely on intestinal surfactants. Finally, the sesame oil formulation shows a 2.7-fold food effect (low fat to medium fat) where Formulation 6 shows a 1.96-fold food effect (low fat to medium fat).
A Brookfield viscometer with CP-51 spindle (Medium—High viscosity spindle) was calibrated. With highest 200 rpm (CP-51), Formulation D (Labrafac-WL-1349-based formulation vehicle with 15% Tween 80) has a viscosity of 23.56 cP. The acceptable viscosity for the encapsulation of the DP-vehicle mixing blend should be in between 0.222 and 3000 Cp.
Moisture abstractability of the liquid formulation components in Hard Gelatin Capsule is shown in
Both Labrafac-WL-1349 and Lauroglycol 90 have a very low potential to absorb moisture. While Tween 80 is hygroscopic, it is only 15% w/w in the vehicle and is not expected to influence the integrity of the capsule shell upon storage.
Each of the oil, propylene glycol laurates composition (Lauroglycol 90), and polysorbate 80 (Tween 80) were weighed and added to a container, and were mixed until a uniform solution was formed. To this solution was added Compound 1. The resulting mixture was stirred until a yellow solution was obtained. The solution was then test visually and under microscope for the absence of Compound 1 crystals. The solution was filled in an amber glass bottle, closed and sealed with CRC cap. The optional flavorant can be added to either the mixture without Compound 1 or to the mixture containing Compound 1.
The homogenized meal was prepared as follow: 30 g daily food (approximately 6% fat by weight) was weighed in a container. 90 mL water was added into the container and contents homogenized.
For low diet groups, animals were fasted overnight and given homogenized normal meal by gavage at 37.5 mL/animal (approximately 15 mL/kg) about 30 mins prior to dosing. The rest diet, approximately 90 g, was given to animals 4 hours post-dose.
The homogenized meal was prepared as follow: 80 g of food weighed in a container. 15 mL eatable corn oil and some water were added into the container and placed it to soften them for about 30 min. Homogenized 20 min to mix well and made up the volume to 250 mL with water.
For medium diet groups, animals were fasted overnight and given homogenized normal meal by gavage at 37.5 mL/animal (approximately 15 mL/kg) about 30 mins prior to dosing. The rest diet (about 103 g), was given to animals 4 hours post-dose.
