FIELD OF THE INVENTION

The present invention relates to the discovery of stable immediate release formulations for the Janus Kinase 3 (JAK3) inhibitor 1-((2S,5R)-5-((7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)-2- methylpiperidin-1-yl)prop-2-en-1-one as its para-toluenesulfonate salt (PF-06651600-15).

BACKGROUND OF THE INVENTION

1-((2S,5R)-5-((7H-Pyrrolo[2,3-d]pyrimidin-4-yl)amino)-2-m ethylpiperidin-1-yl)prop-2-en- 1-one is a selective and irreversible Janus Kinase 3 (JAK3) inhibitor being investigated for the treatment of alopecia areata, vitiligo, ulcerative colitis, Crohn’s disease, psoriasis and rheumatoid arthritis.

Clinical studies were conducted with oral administration of PF-06651600-15 at two different doses (10 and 50 mg tablets) using the material sparing tablet (MST) formulation. The MST formulation contained excipients that were well understood in terms of generating a product with few manufacturing issues, including flow, compression/processability, ejection force, and punch adhesion, and could be used with a drug substances where the knowledge around the physical, mechanical and processing characteristics of the drug were not yet well understood. However, the MST formulation was found to be unstable as PF-06651600-15 readily underwent dimerization and oligomerization. In addition, a noticeable transformation in appearance was also observed for blends and tablets with samples turning from white to yellow/brown over time or exhibiting an intense localized color change. The poor stability profile necessitated the use of refrigerated storage and foil packaging.

Therefore, a need existed for the discovery of stable immediate release tablet or capsule formulations comprising PF-06651600-15 for administration of this compound to treat immune, autoimmune, and inflammatory disorders, in subjects.

SUMMARY OF THE INVENTION

The present invention provides a stable immediate release formulation comprising PF-06651600-15, wherein the formulation has 0.7% w/w or less of a dimer of 1- ((2S,5R)-5-((7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino)-2-methyl piperidin-1-yl)prop-2-en-1-one and a total degradant product amount of 1.2% w/w or less.

In another embodiment, the present invention provides a method of treating an immune, autoimmune, or inflammatory disorder in a subject comprising administering to the subject in need of such treatment a stable immediate release formulation comprising 1-((2S,5R)-5-((7H- pyrrolo[2,3-d]pyrimidin-4-yl)amino)-2-methylpiperidin-1-yl)p rop-2-en-1-one, or a pharmaceutically acceptable salt thereof, including the para-toluenesulfonate salt, wherein the formulation has 0.7% w/w or less of a dimer of 1-((2S,5R)-5-((7H-pyrrolo[2,3-d]pyrimidin-4- yl)amino)-2-methylpiperidin-1-yl)prop-2-en-1-one and a total degradant product amount of 1.2% w/w or less.

Formulation Data

The current formulation has been shown to be unstable with PF-06651600-15 readily undergoing dimerization and oligomerization within the drug product. A noticeable transformation in appearance is also observed for blends and tablets with samples turning from white to brown over time or exhibiting an intense localized color change.

An excipient compatibility screen was initiated to determine which constituents were driving the instability of the MST formulation and to evaluate the impact of alternative excipients on the chemical and physical stability of PF-06651600-15. Samples were prepared as individual binary mixes (i.e. 50% excipient to 50% PF-06651600-15) and stored for 1 week at 70°C/75% RH (relative humidity), after which the blend was assessed for color change and assayed to determine product impurities.

Samples were prepared in size 8 glass dram vials via the following steps: (1) weigh ~ 1 g of excipient into an 8 dram glass vial; (2) add -1.6 g of PF-06651600-15 (-1 gram active agent) into the glass vial; and (3) close the vial and blend the components in a Turbula mixer at -46-49 rpm for 10 minutes. The samples were stored at 70°C/75% RH for one week. These conditions were chosen to study the impact of high humidity known to affect the stability of the MST formulation. The focus was on appearance of the samples and amount of degradation products (as % total area).

The degradation and color change observed with the MST formulation was thought to be primarily driven by disproportionation of PF-06651600 and para-toluene sulfonic acid. In order to determine whether disproportionation of PF-06651600-15 resulted in degradation, experiments were conducted lowering the pH of the formulation below the pH _m ax value of PF- 06651600-15. Samples were prepared with PF-06651600-15 in the presence of a range acids or proton donors. All of the PF-06651600-15 blends prepared with a proton donor demonstrated high levels of degradation product formation (>80%) after one-week storage at 70°C/75% relative humidity (Figure 1). This was also accompanied by a significant change in the appearance of all samples from a white powder to an orange deliquescent (Table 1) demonstrating that these acids were hygroscopic. These results suggested that PF-06651600- 15 was incompatible with high concentrations of acid (low pH micro-environment) and/or hygroscopic excipients in the mixtures.

To further explore the effect the micro-environment pH has on degradation of PF- 06651600-15, several excipients were combined with PF-06651600-15 and stored for 1 week at 70°C/75% RH (Figures 2 and 3). The excipients containing a proton accepting carboxylate with a pH above the pH _max of the tosylate salt (magnesium stearate, sodium starch glycolate, croscarmellose sodium) induced a noticeable color change (Table 1) in the appearance of the binary mixture. In addition, these excipients were accompanied by an elevation in the amount of degradation products within the final sample. The carboxylate groups present in these excipients are capable of accepting a proton from the salt which may facilitate disproportionation. Unexpectedly, di-basic calcium phosphate, also capable of accepting a proton, did not induce a significant amount of color change or degradation. These results demonstrated that degradation of PF-06651600-15 due to excipient contact was unpredictable and also that the excipient micro-environmental pH alone may not explain the instability of PF- 06651600-15.

Hygroscopic excipients have the ability to uptake water and deliquesce above a critical relative humidity which may facilitate color change and an increase in degradation levels of PF- 06651600-15 (Figure 4). Hygroscopic excipients may enhance the rate of disproportionation, and hence degradation of PF-06651600-15, as water facilitates the change in ionization via proton transfer.

The stability of PF-06651600-15 was studied with a range of fillers (Figure 5) including microcrystalline cellulose (Avicel PH102), lactose monohydrate, di-basic calcium phosphate and starch, all of which exhibited no color change and degradant product formation was lower than 1%. Mannitol showed a slight change in the color of the blend (off-white to brown) but demonstrated a high level of chemical stability. A significant localised color change was observed with sorbitol (off-white to orange) despite a low level (<1%) of generated degradant. Xylitol demonstrated both poor chemical stability (12% degradation) and a significant change in appearance (off-white to yellow) throughout the sample. A dynamic vapor sorption (DVS) plot was generated for both mannitol and xylitol (Figure 6) that showed mannitol had low uptake of water whereas xylitol was found to be hygroscopic suggesting that water may contribute to the degradation of PF-06651600-15.

PF-06651600-15 was combined with a range of dry powder lubricants (Figure 7). Magnesium stearate and sodium stearyl fumarate (PRUV) exhibited a high level of chemical degradation accompanied by a noticeable change in the appearance of the sample.

Magnesium stearate turned from off-white to red/brown and PRUV turned from off-white to orange/brown. The remaining lubricants and glidants (glyceryl dibehenate, stearic acid, silicon dioxide) tested showed acceptable chemical stability with PF-06651600-15 with degradation product formation at less than 1% when stored at 70C/75% RH for 1 week. Stearic acid produced a noticeable localized change in the appearance of the sample, glyceryl dibehenate showed a slight coloring (off-white to light yellow), and silicon dioxide did not change color. These results demonstrated that magnesium stearate, used in the MST formulation, was highly incompatible with PF-06651600-15 and therefore may have been a contributing factor to the recorded instability of the drug product. Silicon dioxide appeared to be an acceptable excipient for use within a PF-06651600-15 tablet formulation.

The stability of PF-06651600-15 when combined with excipients to aid disintegration (Figure 8) such as sodium starch glycolate (explotab), used in the MST formulation, exhibited degradant levels greater than 40%, turned color from off-white to yellow, and was deliquescent in appearance. Croscarmellose sodium (Ac-Di-Sol) exhibited levels of degradation products greater than 3% within the sample and a significant observed color change from off-white to light brown. The crospovidone (polyplasdone XL) blend exhibited chemical stability (<1%) with a slight yellowing of the powder.

The results demonstrated that PF-06651600-15 was incompatible with a wide range of excipients. In particular, high levels of degradation were observed when PF-06651600-15 was combined with acids and materials containing carboxylate groups (proton acceptors) suggesting that magnesium stearate and explotab contained within the MST formulation contributed to that formulation’s instability issues. In addition, hygroscopic excipients such as xylitol when combined with PF-06651600-15 generated high levels of degradation products. Excipients found that may be suitable for combination with PF-06651600-15 included the fillers microcrystalline cellulose (MCC), lactose, di-calcium phosphate (DCP), mannitol, and starch; the lubricants/glidants glyceryl dibehenate and silicon dioxide; and the disintegrant crospovidone.

Table 1

Appearance of PF-06651600-15 After 1 Week Storage at 70°C/75% Relative Humidity Based on the results of the excipient compatibility screen, the following excipients were used in various combinations with PF-06651600-15 to formulate immediate release experimental 50 mg tablets: microcrystalline cellulose (Avicel PH 102); dibasic calcium phosphate anhydrous (A-TAB); pregelatinized corn starch (starch 1500); mannitol (perlitol 200 SD); lactose anhydrous; crospovidone (polyplasdone XL); glyceryl dibehenate (Compritol 888 ATO); colloidal silicon dioxide (Aerosil 200); and fumaric acid. Fumaric acid was not part of the excipient compatibility study but was identified as a non-hygroscopic acidifying agent which may enhance product stability by reducing the pH of the formulation. The formulations that were prepared, described in Table 2, contained 10% w/w active PF-06651600-15 with microcrystalline cellulose and a secondary filler in a 2:1 ratio, 5% w/w disintegrant (crospovidone) and 2% w/w lubricant (silicon dioxide or glyceryl dibehenate).

All blends in Table 2 were prepared via the following the steps:

1. Add the components to a suitably sized container in the following order:

Microcrystalline Cellulose (Filler 1)

PF-06651600-15

Filler 2 (Mannitol, Lactose or Starch)

Crospovidone (if required)

2. Blend the batch using a Turbula mixer for 5 minutes at 46rpm

3. Screen the blend through a CoMill using an 813 micron mesh

4. Blend the resulting batch using a Turbula mixer for 5 minutes at 46rpm

5. Screen the lubricant through an 800 micron sieve and add to the batch.

6. Blend the batch using a Turbula mixer for 2 minutes at 46rpm Formulation F was a repeat of Formulation A except that silicon dioxide was substituted for glyceryl dibehenate to ascertain the impact on processing of the two different lubricants.

Formulation G was a repeat of formulation B except that 2% w/w fumaric acid was added at the end of step 1 of the blending process to determine the use of this excipient as a potential stabilizing agent.

Table 2

Experimental Tablet Formulations A-G

Tablets were prepared using a Korsch XP1 tablet press to generate tablets under the following conditions: round 10mm diameter src B-Type tooling; target tablet weight: 500mg ± 4%; and target tablet crushing strength 10kp. One hundred fifty tablets were produced from each batch to provide information on the physical properties of the tablet (weight, diameter, thickness and crushing strength) and to provide samples for drug product stability, dissolution testing, and solid-state stability. Tablet measurements were taken on three to four tablets throughout the run to ensure product consistency.

During the compression of the blends on the Korsch XP1 , observations were made with regard to flow, processability (ease of compression), and punch adhesion. The ejection force value was taken directly from measurements made by the Korsch (Table 3).

These observations revealed that silicon dioxide could be used in small amounts to aid flow but cannot be used as a lubricant due to the high ejection forces recorded. In addition, the higher levels of silicon dioxide in formulation A affected the density of the blend leading to the compression and processability issues that were observed with Lot A as a result of the low bulk density of this formulation. The inclusion of glyceryl dibehenate, rather than S1O2, reduced the ejection force. Of the four alternative fillers investigated (DCP, starch, mannitol and lactose) the mannitol blend was observed to exhibit poor flow (within the hopper) and had the greatest levels of punch adhesion. Table 3

Summary of Compression Process Observations for Experimental Tablet Formulations A-G

Disintegration was assessed for lots A, B, C, E and G in 0.01 M HCI medium to ascertain whether the amount of disintegrant in tablets was suitable and in cases where no disintegrant was present whether the tablets disintegrate within an acceptable time. Disintegration results obtained on lots A, B, C, E and G are summarized and compared to that of the current formulation in Table 4. All batches disintegrated in less than thirty seconds, similar to the MST formulation. The lack of disintegrant in lots C and E did not have any adverse impact on the disintegration time of the tablets.

Table 4

Disintegration Times for Experimental Tablet Formulations A, B, C, E, and G Compared to the MST Formulation

Dissolution was assessed for lots A, B, C, E and G at 75 rpm in 500 ml_ of 0.01 M HCI medium and 900 ml_ of pH 4.5 acetate medium (Figure 9). The first set of conditions was chosen because that was the method used to monitor performance of the MST formulation.

The second set was chosen as alternative conditions suitable to show discrimination between the batches. All batches disintegrated in less than a minute, similar to the MST formulation. The lack of disintegrant in lots C and E did not have any adverse impact on the disintegration time of the tablets.

Chemical stability was assessed under the Accelerated Stability Assessment Program (ASAP) conditions using high performance liquid chromatography with ultra-violet detection

(HPLC-UV) analysis. Tablets from experimental lots A, B, C, E and G and from the MST formulation were stored under the conditions as stated in Table 5 with appearance and purity analysis performed at each time point. The level of degradation products as a percentage of total area was used to ascertain the stability of PF-06651600-15 within the formulation.

Table 5 ASAP Conditions

*RH means relative humidity

Figure 10 summarizes the results for experimental lots A, B, C, E and G and the MST formulation when placed under ASAP conditions. The MST tablets stored at the highest relative humidity condition (75% RH) recorded the lowest ASAP values including the MST tablets stored for seven days at 70°C/75%RH and fourteen to twenty-eight days at 60°C/75%RH. This trend was not observed with the tablets from the experimental formulations as their ASAP values ranged between 95.0% - 105.0%. Numerical ASAP values for the experimental lots are provided in Table 6 versus 5°C control.

Figures 12, 13, 14, and 15 provide the level of dimer detected in tablets prepared from experimental formulations A, B, C, E and G and from the MST tablets in an open dish for six months at 5°C, 25°C/60%RH, 30°C/75%RH, and 40°C/75%RH, respectively. When stored at

5°C, none of the formulations showed any significant increase in dimer. When stored at 25°C/60%RH, no increase of the dimer was observed for the experimental tablets (A, B, C, E and G) after six months whereas detection of the dimer rose above the acceptable criteria of 0.7% for the MST tablets after six weeks. When stored at 30°C/75%RH, the level of dimer increased for all the batches but remained below 0.7% for the experimental tablets whereas the level of dimer in the MST tablets was far above the acceptance criteria after six weeks. When stored at 40°C/75%RH, the level of dimer followed a similar trend to that at 30°C/75%RH up to three months for lots A, B, C, E and G. Unexpectedly at the six month date, the percentage of dimer detected slightly decreased for lots A, C and E. Further, the total percentage of degradation products detected decreased for lots A and E after six months at 40°C/75%RH (Figure 16). This decrease in degradation over time may be due to formation of the trimer and/or higher oligomers.

Table 8 provides the numerical comparison of percentages of dimer and total degradation products detected in experimental tablets A, B, C, E, and G and in the MST tablets at six weeks, three months, and six months.

With regard to appearance (Table 9), no change in color was observed in any of the tablets prepared from experimental formulations A, B, C, E, and G after twenty eight days storage at 50°C/75% RH, 60°C/40% RH and 70°C/10% RH. Similarly, no change was recorded after seven days storage at 70°C/75% RH. Yellow mottling was observed for experimental tablets A, B, C, and E after seven days at 80°C/ 40% RH but not for the tablets from lot G (starch and fumaric acid). The tablets from lot A (DCP filler) exhibited discoloration on the sides of the tablets after twenty-eight days at 60°C/75% RH. The tablets from lot E (lactose filler) showed signs of mottling after twenty-eight days at 70°C/40% RH. The tablets from lot G (starch and fumaric acid) displayed a light yellowing after twenty-eight days at 60°C/75% RH. The ASAP appearance results demonstrated that the experimental formulations A, B, C, E, and G had improved behavior with respect to color change when compared to the MST tablets. Table 9

Appearance Results for Experimental Tablet Formulations A, B, C, E, and G

Under ASAP Conditions Between 1 and 28 Days With regard to appearance at 6 weeks, 3 months, and 6 months, yellow and brown spots were observed for the MST tablets at six weeks at 30°C/75%RH and 40°C/75%RH. For the tablets prepared from experimental formulations A, B, C, E, and G, only lot A showed a change in color when stored at 40°C/75%RH for three months (off-white) and six months (pale yellow). The six week, three month, and six month appearance results are provided in Table 10 for the tablets prepared from experimental formulations A, B, C, E, and G and from the MST tablets.

Table 10

6 Week, 3 Month, and 6 Month Appearance Results for

Experimental Tablets A, B, C, E, and G and for the MST Tablets The results for the experimental formulations A, B, C, E, and G demonstrated that these formulations have an improved stability profile compared to the MST formulation used in the Phase II clinical studies. The six-month stability profiles showed that the formation of the dimer product in the experimental formulations remained below 0.7% under all of the conditions investigated including 40°C and 75% relative humidity. In terms of appearance only the tablets containing di-calcium phosphate (DCP) exhibited any change in color likely due to DCP acting as a proton acceptor albeit a relatively weak one compared to the proton acceptor excipients excluded from this study.

Although the experimental formulations showed improved stability, further studies were warranted as each formulation had advantages and shortcomings with respect to the production of an immediate release tablet. The use of DCP was deemed not favored due to the discoloration observed over the six-month storage period. Mannitol, while potentially generating the most stable blend, exhibited the greatest observable challenge with respect to handling, processing and punch adhesion. Starch containing blends were easier to process but there were concerns around batch to batch variability of this particular excipient. Lactose appeared to be relatively easy to process and was considered an alternative to DCP based tablet formulations, however, there were concerns regarding the use of this excipient with lactose intolerant subjects. From a tablet formulation only perspective, the preferred order was determined to be lactose, starch, and mannitol.

With regard to the use of lubricants or flow agents, glyceryl dibehenate reduced the ejection force compared to samples containing silicon dioxide which supported the use of glyceryl dibehenate as a suitable lubricating agent. However, bulk flow observations suggested that glyceryl dibehenate detrimentally impacted tablet hardness and punch adhesion. Further studies were clearly warranted to study the effect of formulation composition (e.g. filler ratio) and potentially the addition of small levels of silicon dioxide (£0.5%) as a flow agent.

The addition of the disintigrant crospovidone to the formulation did not appear to impact disintegration, dissolution, nor the stability of the product. Nonetheless, the optimum amount of disintegrant included in the formulation required further studies.

Fumaric acid was investigated to determine whether the inclusion of a non-hygroscopic acidifying agent enhanced the stability of the drug product. Results appeared to demonstrate that the addition of this material had no impact on the stability of the experimental tablets. Whether tablet stabilization was due to the addition of fumaric acid or the absence of proton acceptor excipients required further experiments.

While stability results for the experimental formulations supported the realization that an immediate release tablet drug product was feasible for PF-06651600-15, several areas still needed to be investigated to advance a formulation from a concept to clinical and commercial product. In particular, further development was required to develop an optimized formulation and a robust manufacturing process. Studies examined direct compression only and these limited observations indicated that the current blends had issues with respect to both flow and punch adhesion. Lubricant and disintegrant levels, filler ratios and PF-06651600-15 content all required further investigation. In addition, blending, roller compaction and compression conditions needed to be explored to understand the impact of product processing upon the formulation.

Furthermore, film coating studies were required to demonstrate whether this additional step would negatively impact the stability of the PF-06651600-15 tablet. Previous results demonstrated that an aqueous coating of the MST tablet induced degradation of PF-06651600- 15. Additional experiments using a stable tablet formulation with both an aqueous and a solvent coat were required to determine whether a film coated tablet was a viable option with regard to PF-06651600-15 product development. If film coating studies induced instability of PF-06651600-15, then father studies using lactose, starch and mannitol formulations would be warranted to determine whether an encapsulated product would be stable.

In sum, the experimental formulations for PF-06651600-15 demonstrated that, with compatible excipients, an improved immediate release tablet compared to the MST tablet appeared to be possible. However, further research was required to determine whether these formulations were stable beyond six months and whether the formulations were amendable to further manufacture processing including powder flow, dry granulation/roller compaction, tablet film coating, and encapsulation.

A twelve month stability study was conducted for the 50mg tablets prepared from the experimental formulations A, B, C, E, and G compared to the 50mg tablet prepared from the MST formulation under the following conditions 5°C, 25°C/60% RH, and 30°C/75% in an open dish. All the tablets remained below the acceptance criteria of 0.7% for detection of dimer and total degradation products at 5°C for twelve months (Figures 17 and 18). With regard to dimer formation, the study results showed that all of the experimental tablets remained below the acceptance criteria of 0.7% after twelve months in an open dish under the conditions of 25°C/60% RH (Figure 19) and 30°C/75% (Figure 20). The experimental tablets exhibited similar profiles with regard to dimer production while the tablets derived from formulation A, containing DCP, produced the highest amounts of dimer under both conditions. The MST tablets exceeded the acceptance criteria of 0.7% for dimer detection within two months under both conditions. Wth regard to the percentage of total degradation products detected, again, all the experimental tablets remained below the acceptance criteria of 0.7% over the twelve month period in an open dish under the conditions of 25°C/60% RH (Figure 21) and 30°C/75% (Figure 22). Further, experimental tablets B, C, E, and G exhibited similar total degradation product profiles while the tablets from formulation A demonstrated a linear upward trend under both conditions reaching 0.48% under the 30°C/75%RH conditions at twelve months (Table 11). The MST tablets exceeded the acceptance criteria of 0.7% total degradation products detected within 2 months for both conditions.

Table 11

Percentages of Dimer and Total Degradation Products Detected for Experimental Tablets A, B, C, E, and G and for the MST Tablets After 12 Months

The degradation results disclosed herein for the experimental tablets demonstrated that tablets derived from formulation C (Table 2) had produced the lowest amount of degradation products under most of the conditions studied at three months (Table 8), six months (Table 8), twelve months (Table 11), and under ASAP conditions (Table 7 and Figure 11). However, the manufacturing characteristics with regard to flow and punch adhesion were poor for blend C (Table 3).

Studies were therefore conducted on the stability of experimental formulation C encapsulated in hydroxypropyl methylcellulose (HPMC) capsules compared to tablet and powder blend, where the powder blend was not compacted into a tablet nor encapsulated. The purpose was to evaluate whether PF-06651600-15 compatibility could be achieved between a powder blend and a HPMC capsule shell in order to mitigate any tablet production issues that may arise due to poor powder blend processing characteristics. The stability of PF-06651600- 15 after HPMC encapsulation was not predictable, in part, because of the potential detrimental effect formaldehyde and/or formic, leached from the capsules, might have on product stability.

HPMC capsules (Vcaps Plus, size 0, white/opaque) were each filled with 250mgs of experimental formulation C (25mg API dose) which was the maximum amount of blend that could be contained within this capsules size. Chemical stability was assessed under ASAP conditions after the capsules were opened and the bottom half containing blend was positioned upright in a glass vial to allow the blend to equilibrate with the environmental conditions while maintaining contact with the capsule shell. The harsher ASAP conditions, 70°C/75%RH and 80°C/40%, were not assessed in this study due to the properties of the HPMC shell. With regard to appearance of the encapsulated experimental blend C, no bulk or localized color changes were observable in any of the samples.

The dimer and total degradation product results (Table 12) demonstrated that a 10% w/w active blend containing mannitol and microcrystalline cellulose in a ratio of 2:1 and 2% glyceryl dibehenate exhibited acceptable compatibility with a size 0, HPMC capsule. The encapsulated product displayed an improved accelerated stability profile when compared to an equivalent tablet but was less stable than the blend alone (Figure 23 and Tables 13 and 14).

With regard to formaldehyde and formic acid as potential impurities leached from HPMC capsules, degradation experiments were conducted with PF-06651600-15 in the presence of each impurity separately. For formaldehyde after 3 days at 40°C, a main degradation product was formed at a level of about 80%. The mass spectrometry analysis of the product was consistent with the addition of -CH20 to PF-06651600-15. After 3 days at 40°C in presence of formic acid, the level of total degradation products reached 24%. The degradation products generated with formaldehyde and formic acid were not detected during analysis of the capsules samples stored under ASAP conditions.

The HPMC capsule degradation results suggested that an encapsulated PF-06651600- 15 drug product was acceptable. However, experimental formulation C only achieved a fill weight of 250mg or 40mgs of PF-06651600-15 (25mgs active) in the size 0 capsule. In comparison, the higher dose MST tablets used in previous clinical studies contained just over 80mgs of PF-06651600-15 (50mgs API). Further studies were therefore required to assess whether increased drug loading was possible in a suitably sized capsule to attain higher API doses or whether optimization of the blend ratios could enhance flow and bulk density to allow commercial production of a HPMC capsule containing 50mgs of API.

A review of manufacturing properties for filler excipients showed that lactose anhydrous had similar properties as mannitol except that lactose had better flow properties (Table 3).

Also noted were the stability results for experimental formulation E, blended with lactose anhydrous. Blend E was slightly less stable than the mannitol containing blend C, however, blend E was below the acceptable limit of 0.7% dimer formation for most of the conditions tested (Tables 7 and 8). Lactose anhydrous was used in blend E rather than lactose monohydrate due to concerns regarding the impact of water upon the degradation of PF- 06651600-15. To further explore the hygroscopic properties of lactose monohydrate, dynamic vapor sorption (DVS) traces were generated for both lactose anhydrous and lactose monohydrate (Figure 24). The results for both were similar as the mass increased less than 2% at a humidity of 90% RH. Lactose monohydrate increased -0.55% and lactose anhydrous increased -1.1%. The DVS results indicated that either lactose anhydrous or lactose monohydrate may be acceptable filler excipients in a PF-06651600-15 formulation.

Due to the processing and stability concerns in generating an immediate release tablet, an encapsulated formulation was proposed as a route to commercial drug product development with a target capsule dose range or 10-100mgs. Blend C was used in the HPMC encapsulated studies and had poor flow properties leading to low capsule fill rates and hence low dosages of active drug. Therefore, studies were initiated with four new experimental formulations, H, I, J, and K containing: lactose monohydrate as the second filler; higher amounts of PF-06651600- 15; and different particle sizes to determine the effect of drug loading and API particle size on the physical characteristics of formulations H, I, J, and K (Tables 15 and 16).

Experimental blends H, I, J, and K were prepared using a blend, screen blend method. Microcrystalline cellulose, PF-06651600-15, lactose monohydrate, crospovidone and glyceryl dibehenate were added to a suitable blending container and blended for 10 minutes at -46 rpm. The blend was screened through a co-mil fitted with an 813 micron screen and then blended for 10 minutes at ~46rpm.

A Dott Bonpace InCap capsule filling machine was used to assess the suitability of the four blends for filling into size 0 capsule shells. The filling parameters used are described in Table 17. Fill weights were calculated to produce a 50 mg capsule using the 15% blends and a 100mg capsule from the 40% blends.

Particle size distribution for experimental blends H, I, J, and K was determined using laser diffraction and the results are listed in Table 18.

Table 18 Particle Size Results for Experimental Blends H, I, J, and K

Blend flow values were measured by shear forces (flow function co-efficient), powder compressibility (Carr’s Index), and the powder’s ability to fall freely through a hole in a disk (flowdex). The measured flow values listed in Table 19 demonstrated that the larger particle size distributions (i.e. greater D[ _V ,o.i], D[ ,o.s] and D[ _V ,o.9] values) had better measured flow values. Unmilled Blends H and I had the largest particles and excellent measured flow values. The milled blends, J and K, had the smallest particles with acceptable to good measured flow values. Table 19

Comparison of Measured Flow Values for Experimental Blends H, I, J, and K

With regard to stability, all the experimental blends H, I, J, and K showed good stability over a twelve-month period at 30°C/65% RH with respect to appearance (Table 20). All remained white to off-white powders, none were deliquescent. The capsule powder was observed to be loosely compacted and the powder plug was easily broken with little force.

Table 20

Experimental Blends H, I, J, and K Stability Appearance Over 12 Months Figure 25 provides the dimer concentration detected in experimental blends H, I, J, and K when stored at 30°C and 65% relative humidity over a twelve-month period. All the encapsulated blends maintained a level of dimer content below the maximum acceptable limit of 0.7%. The milled blends, J and K, generated higher concentrations of dimer than the unmilled blends, H and I, suggesting that particle size played a role in the amount of dimer produced in these blends. In particular, blend I, unmilled 40% API, was more stable than blend K, milled 40% API.

Table 21 provides the percentages of dimer and total degradant products detected at eight weeks under ASAP conditions for experimental blends H, I, J, and K. The data aligned with the results obtained over one year at 30°C/65%RH (Figure 25). Lower levels of degradant product formation were observed when a larger API particle size was used within the formulation, blends H and I. In contrast, the smaller particle size used in blends J and K generated higher amounts of degradant. In particular, blend J, containing the milled smaller particle size and the lower product load, 15% w/w PF-06651600-15, in a gelatin capsule was the least stable blend.

Figure 26 provides the mean assay values (% label claim) for experimental blends H, I,

J, and K when stored at 30°C and 65% relative humidity over a twelve-month period. Despite some minor variation over this period, all four blends maintained content similar to that recorded at the initial timepoint (within ±2%). There was no reduction in the assay amounts recorded for any blend during the twelve-month period. Table 22 provides the numerical values (% label claim) generated for blends H, I, J, and

K under ASAP conditions.

Table 22

ASAP Results for Experimental Encapsulated Formulations H, I, J, and K

Figure 27 provides a comparison of dissolution data for experimental blends H, I, J, and K after one year at 30 65% relative humidity. All blends demonstrated greater than 80% dissolution after 30 minutes. The blend prepared with milled PF-06651600-15 at a concentration of 15% w/w Active was placed into gelatin capsules as opposed to the HPMC shells which were used to encapsulate the rest of the batches. This may explain the discrepancy recorded over the first 5 minutes of the dissolution test as there was a delay in the rupture of the HPMC capsules which in turn prevented the release of PF-06651600-15 resulting in the 0% dissolution recorded over the first five minutes of the dissolution test for blends H, I, and K. Figure 28 provides segregation contour plots for experimental blends H, I, J, and K. These plots provide a visual interpretation of PF-06651600-15 concentration throughout the blends. Results indicated that, despite hot spots within the blend, the 40% w/w active blends, I and K, were less prone to segregation regardless of PF-06651600-15 particle size. The 15% w/w active blends, H and J, demonstrated a greater variation in PF-06651600-15 concentration across the blend.

In summary, experimental formulations H, I, J, and K exhibited acceptable stability as shown by the appearance and amount of degradant produced by each blend. With regard to particle size, an increase in the particle size of PF-06651600-15 led to a reduction in dimer and total degradant product formation and also improved the blend manufacturing properties. Wth regard to product load, an increase in drug load reduced powder segregation. The data disclosed herein, therefore, supported commercial formulations comprised of microcrystalline cellulose, lactose monohydrate, polyvinylpyrrolidone (crospovidone), and glyceryl dibehenate with larger PF-06651600-15 particle size and higher percentage of PF-06651600-15 loads encapsulated in HPMC capsules.

In order to confirm the viability of the proposed commercial formulation, two batches of blend I (unmilled) and two batches of blend K (milled) were separately prepared and encapsulated in size 0 HPMC capsules (Table 23).

Table 23 Re-Prepared Blend I and Blend K Details

* 40% w/w API

The blends were then subjected to degradation studies to determine the percentage of dimer and total degradant products detected under the conditions and at the time points described in Table 24. Table 24

Percentage Dimer and Total Product Degradants Detected for Re-Prepared Blends I and K

The degradation results for blends I and K confirmed that both blends were stable and that blend I composed of the unmilled larger PF-06651600-15 particles was more stable than blend K composed of the milled smaller PF-06651600-15 particles. Therefore, based on the results described herein, an immediate release commercial formulation was postulated for 30mg, 50mg, and 100mg doses of PF-06651600 in HPMC capsules comprising: about 60.10% PF-06651600-15 (37.50% active amount); about 15.95% microcrystalline cellulose; about 15.95% lactose monohydrate; about 3.00% crospovidone; and about 5.00% glyceryl dibehenate.

Immediate release capsules containing 30mg, 50mg, and 100mg doses of PF- 06651600-15 were prepared by combining: 60.10% PF-06651600-15; 15.95% microcrystalline cellulose (Avicel PH102); 15.95% lactose monohydrate (Fast Flo 316); 3.00% crospovidone type A (Polyplasdone XL); and 5.00% glyceryl dibehenate (Compritol 888 ATO, vegetable origin) in a suitably sized blending container and blended for 10 minutes at 30 rpm (300 revolutions) using a Turbula mixer. The blend was filtered through a cone mill fitted with a -0.9 mm aperture (032R) screen at a speed of -1000 rpm using a round rotor type and then blended for 10 minutes at 30 rpm (300 revolutions) using a Turbula mixer. 80.00 mgs of blend were filled into #4 Hypromellose capsules using a dosator disk encapsulation machine to provide the 30 mg doses of API (PF-06651600) in HPMC capsules. 133.333 mgs of blend were filled into #3 hypromellose capsules using a dosator disk encapsulation machine to provide the 50 mg doses of API (PF-06651600) in HPMC capsules. 266.667 mgs of blend were filled into #1 Hypromellose capsules using a dosator disk encapsulation machine to provide the 100 mg doses of API (PF-06651600) in HPMC capsules (Table 25).
