[0011] As used herein, (S)-3-(3-(1-methyl-2-oxo-5-(pyrazolo[1,5-a]pyridin-3-yl)-1H-imidazo[4,5-b]pyridin-3(2H)-yl)piperidin-1-yl)-3-oxopropanenitrile (Compound I) [ka] Disclosed are formulations and methods for making the same, comprising: In some embodiments, the formulation comprises about 0.5-11% by weight of Compound I, about 87.0-99.0% by weight of lactose, and about 0.5-2.0% by weight of magnesium stearate.
[0012] The formulations and preparation methods disclosed herein exceed expectations in that they result in mixtures of Compound I, magnesium stearate, and lactose with sufficient drug content and uniformity (content uniformity). This discovery led to clinical trials of formulations containing Compound I, lactose, and magnesium stearate. Prior to this discovery, the lack of uniformity and low drug content in existing formulations of Compound I prevented clinical trials of Compound I.
[0013] Also provided herein are methods of treating respiratory diseases (e.g., COPD and asthma) using formulations comprising Compound (I), lactose, and magnesium stearate. Such methods of treatment unexpectedly demonstrate clinically significant benefits against eosinophilic inflammation in asthma patients.
[0014] A further unexpected discovery is that a formulation containing Compound (I), lactose, and magnesium stearate results in clinically meaningful reductions in FeNO at low doses delivered by a single capsule. In contrast, other JAK inhibitors require higher API doses, which are achieved by administering multiple capsules. Therefore, the present specification also provides a method for reducing exhaled nitric oxide (FeNO) levels using a formulation containing Compound (I), lactose, and magnesium stearate.
[0015] definition It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.

[0099] The safety and efficacy of solid pharmaceutical products, as well as their robust performance, are ensured by meeting specified critical quality attributes (CQAs). Among them, the content uniformity (CU) of a drug product is the most important. Content uniformity is defined as a measure of how evenly the API is distributed throughout the mixture. A blend with excellent content uniformity has the same concentration of API throughout the blend (e.g., top, middle, and bottom). Content uniformity is measured by taking multiple samples from various locations throughout the blend and analyzing each sample by HPLC or a similar technique to determine the API concentration in each sample. Content uniformity is expressed as the percent relative standard deviation (RSD) of the pooled samples based on the concentration of the drug mixture.
[0100] In one embodiment, the content uniformity of a pharmaceutical formulation of Compound I has a percent relative standard deviation (RSD) of about 5% or less. In another embodiment, the content uniformity of a pharmaceutical formulation of Compound I has an RSD of about 4.0% or less. In yet another embodiment, the content uniformity of a pharmaceutical formulation of Compound I has an RSD of about 3.0% or less.
[0101] In yet another embodiment, the content uniformity of the pharmaceutical formulation of Compound I has an RSD of about 2.0% or less. In one embodiment, the content uniformity of the pharmaceutical formulation of Compound I has an RSD of about 1.5% or less. In another embodiment, the content uniformity of the pharmaceutical formulation of Compound I has an RSD of about 1.0% or less. In yet another embodiment, the content uniformity of the pharmaceutical formulation of Compound I has an RSD of about 0.5% or less.
[0102] Compound I is typically administered as a pharmaceutical formulation together with a pharmaceutically acceptable carrier or excipient. In one embodiment, the present disclosure relates to a pharmaceutical formulation of Compound I comprising one or more pharmaceutically acceptable excipients. Suitable compositions may be in the form of a tablet, a capsule, or an inhalable composition. In one embodiment, the present disclosure provides a capsule comprising Compound I. In one embodiment, the present disclosure provides a capsule filled with a formulation comprising Compound I. In one embodiment, the present disclosure provides a blister filled with a formulation comprising Compound I. In one embodiment, the present disclosure provides an inhalable composition comprising Compound I.
[0103] The formulation can be delivered by a dry powder inhaler (DPI) for the treatment of respiratory diseases. When administered by inhalation using a dry powder inhaler, Compound I can be administered as a dry powder formulation containing one or more carrier substances. Suitable inhalation carriers are known in the art, and in one embodiment, include crystalline sugars such as monosaccharides or disaccharides. In one embodiment, the carrier is lactose. Compound I can also be administered as a dry powder formulation without a carrier substance.
[0104] The dry powder formulations of the present disclosure may also have additional additives, such as force control agents. Force control agents are additives that reduce cohesion between fine particles in the powder formulation, thereby promoting deagglomeration when the powder is dispensed from an inhaler. Suitable force control agents, such as magnesium stearate, are known in the art to enhance the stability of dry powder formulations. In one embodiment, the force control agent is a metal stearate, such as magnesium stearate.
[0105] The dry powder formulations of the present disclosure can be administered using a single-dose dry powder inhaler or a multi-dose dry powder inhaler. In a non-limiting example, the dry powder formulations of the present disclosure can be administered using various dry powder inhalers, such as GyroHaler® or Miat®, Monodose RS01, or a lever-operated inhaler such as that disclosed in WO 2009 / 092770. In another non-limiting example, the dry powder formulations of the present disclosure can be administered using an open-inhale-close device. In a further embodiment, the present disclosure provides a kit comprising an inhaler in combination with a formulation provided herein. In a further embodiment, the present disclosure provides a kit comprising a dry powder inhaler in combination with a pharmaceutical formulation provided herein. In one embodiment, the present disclosure provides a kit comprising a Miat single-dose RS01 dry powder inhaler in combination with a pharmaceutical formulation provided herein.
[0106] For pulmonary administration, the size of API particles is crucial in determining the site of absorption. To be transported deep into the lungs, API particles must be very fine, e.g., have a mass median aerodynamic diameter of less than 10 μm. Particles with an aerodynamic diameter greater than 10 μm are likely to impact the pharyngeal wall and typically do not reach the lungs. Particles with an aerodynamic diameter between 5 μm and 0.5 μm typically deposit in the respiratory bronchioles, while smaller particles with an aerodynamic diameter between 2 μm and 0.05 μm are more likely to deposit in the alveoli.
[0107] In another embodiment, the formulation is suitable for aerosol delivery to a subject.
[0108] In yet another embodiment, when aerosolized, the mass median aerodynamic diameter (MMAD) is about 5.0 μm or less (e.g., 0.5-5.0 μm, 1.0-4.0 μm, 1.5-3.0 μm, or 1.5-2.5 μm). In yet another embodiment, when aerosolized, the mass median aerodynamic diameter (MMAD) is about 1.9 μm. In another embodiment, when aerosolized, the mass median aerodynamic diameter (MMAD) is about 1.8 μm.
[0109] Another important parameter for inhaled dry powder formulations is dose delivery efficiency, as measured by the fine particle fraction (FPF). The FPF therefore provides an in vitro indication of the efficiency of the device / formulation in delivering the API to the lungs.
[0110] In one embodiment, when aerosolized, Compound I has a fine particle fraction (FPF) of about 60% or greater (e.g., 60-100%, 65-90%, 65-85%, 65-80%, 70-80%, or 70-78%). In another embodiment, when aerosolized, Compound I has an FPF of about 72.5-77.5%.
[0111] The proportion of each metered dose that is composed of drug particles of the correct size (MMAD) for deposition at the desired site in the lung must also be uniform (stable) (i.e., within a specified range). This proportion is known as the fine particle mass (FPM) and represents the proportion of the metered dose that is composed of drug particles having an MMAD within the range of about 1 micron to about 5 microns. As is well known in the art, the FPM of a pMDI can be determined with a cascade impactor, such as the Next Generation Impactor (NCI). The FPM is the amount of the metered dose collected at a particular stage of the cascade impactor (e.g., NGI).
[0112] In yet another embodiment, when a capsule containing about 1.0-3.0 mg of Compound I is aerosolized, the fine particle mass (FPM) of Compound I is 900-1800 μg. In yet another embodiment, when a capsule containing about 1.0-3.0 mg of Compound I is aerosolized, the fine particle mass (FPM) of Compound I is 900-1500 μg. In yet another embodiment, when a capsule containing about 1.0-3.0 mg of Compound I is aerosolized, the fine particle mass (FPM) of Compound I is 900-1200 μg.
[0113] In yet another embodiment, when a capsule containing about 3.0-5.0 mg of Compound I is aerosolized, the FPM of Compound I is 1750-2450 μg. In yet another embodiment, when a capsule containing about 3.0-5.0 mg of Compound I is aerosolized, the FPM of Compound I is 1750-2350 μg. In yet another embodiment, when a capsule containing about 3.0-5.0 mg of Compound I is aerosolized, the FPM of Compound I is 1850-2250 μg. In yet another embodiment, when a capsule containing about 3.0-5.0 mg of Compound I is aerosolized, the FPM of Compound I is 1950-2250 μg.
[0114] For dry powder inhalers (DPIs), it is important to balance the flow characteristics of the dry powder within the inhaler with the plume characteristics upon inhalation. Coarse carrier particles, usually lactose, are used to aid the flow characteristics of the medication, but it is important to ensure that the active ingredient separates from the coarse carrier upon inhalation, allowing fine particles of the active ingredient to be taken up in the lungs. It is important that this process occurs in a consistent manner to provide an adequate dose over the life of the inhaler. That is, the inhaler must actually provide a consistent delivered dose and fine particle mass from the first dose to the last dose.
[0115] In yet another embodiment, the delivered dose of Compound I when aerosolized is at least about 80% (e.g., 60-100%, 65-100%, 70-100%, and 75-90%) of the target dose. In yet another embodiment, the delivered dose of Compound I when aerosolized is 78-88% of the target dose.
[0116] In one embodiment, compound I has a copper Kα1 activity of: Approximately 8.25°, Approximately 13.25°, Approximately 15.40°, Approximately 17.65°, and It is a polymorph (Form II) with a diffraction angle (2θ) of about 25.39°.

[0120] How to use Compound I has been shown to be a potent inhibitor of JAK family enzymes, specifically JAK1, JAK2, JAK3, and TYK2. For example, the biological activity of this compound is described in WO2011 / 051452 (incorporated herein by reference in its entirety).

[0195] In another embodiment, the formulation further comprises lactose and magnesium stearate.In yet another embodiment, the formulation is administered in a single capsule.
[0196] Preparation method Formulations containing Compound I were found to contain large aggregates upon visual inspection. Notably, formulations prepared by blending the lactose:MgSt premix with the API:MgSt premix without an intermediate co-milling step resulted in greater variability in content uniformity (i.e., lower levels of uniformity) and lower assayed drug concentrations. In contrast, formulations prepared with an intermediate co-milling step, i.e., co-milling the lactose:MgSt premix and API:MgSt premix prior to blending, exhibited improved content uniformity. This suggests that an additional co-milling step may be necessary to blend the formulation components to produce formulations containing Compound I suitable for clinical trials.

[0207] Additionally, formulations containing Compound I were found to electrostatically adhere to plastic powder handling materials. Specifically, when the formulations were transferred from plastic transfer bags, visual inspection revealed that a significant amount of bulk powder adhered to the interior walls of the transfer bags. Electrostatic adhesion resulted in formulations with significant variability in drug content measurements and less-than-optimal content uniformity. Electrostatic adhesion was reduced by replacing the plastic transfer bags with clean GMP stainless steel containers and incorporating a settling period (e.g., 10-120 hours) into the formulation process before any substantial handling or processing. Thus, formulations prepared using clean GMP stainless steel containers and with a settling period before testing consistently exhibited increased drug content and improved content uniformity.

[0270] In some embodiments, the method is carried out using stainless steel powder handling materials, including stainless steel spatulas, stainless steel scoops, stainless steel funnels, and stainless steel containers.
[0271] The drug particles or pharmaceutically active agent particles (also referred to herein as "active particles") in the formulations of the present disclosure must be aerosolized into ultrafine aerosols (see above) so that they can be delivered to the appropriate target area in the lungs. Typically, for pulmonary deposition, the active particles have a diameter of less than 10 μm, often 0.1-7 μm, 0.1-5 μm, or 0.5-5 μm.
[0272] For a formulation to reach the deep lungs or bloodstream via inhalation, the active agent in the formulation must be in the form of very fine particles, e.g., with a mass median aerodynamic diameter (MMAD) of less than 10 μm. It is well recognized that particles with an MMAD greater than 10 μm are likely to impact the pharyngeal wall and typically do not reach the lungs. Particles with an MMAD in the 5-2 μm range generally deposit in the respiratory bronchioles, whereas particles with an MMAD in the 3-0.05 μm range are more likely to deposit in the respiratory bronchioles and alveoli, potentially providing benefits to the inflammation of the narrow airways seen in respiratory diseases, including asthma and COPD.
[0273] When dry powders are produced using conventional processes, the active particles vary in size, and in many cases, this variation can be significant. This can make it difficult to ensure a sufficiently high percentage of the active particles are the appropriate size for administration to the correct site. Therefore, it is desirable to have a dry powder formulation with as narrow a size distribution of the active particles as possible. This improves dose efficiency and reproducibility. Fine particles, i.e., particles with an MMAD of less than 5 μm and smaller, tend to become increasingly thermodynamically unstable as their surface area-to-volume ratio increases. This leads to an increase in surface free energy with decreasing particle size, resulting in an increased tendency for particles to agglomerate. The aggregation of fine particles and their adhesion to the walls of the inhaler can result in the particles exiting the inhaler as large, stable agglomerates, or they may be unable to exit the inhaler and remain attached to the interior of the inhaler, or they may further clog or block the inhaler.
[0274] The uncertainty in the extent to which stable particle agglomerates form between inhaler actuations, and even between different inhalers and different batches of particles, leads to poor dose reproducibility. Furthermore, agglomerate formation means that the MMAD of the active particles can increase significantly, preventing active particle agglomerates from reaching the required parts of the lung.
[0275] These micron to submicron particle sizes required for deep lung delivery lead to the problem that the inhalable active particles tend to be highly cohesive, meaning that the particles generally have poor flowability and aerosolize poorly.
[0276] To improve the properties of powder formulations, particularly the flowability and dispersibility of the formulation, dry powder formulations often contain additives intended to reduce agglomeration between fine particles in the dry powder formulation. The additives are thought to disrupt the weak binding forces between small particles, helping them to remain separated and reducing adhesion of such particles to each other, to other particles in the formulation (if present), and to the interior surfaces of the inhaler. If particle agglomerates form, the addition of additive particles reduces the stability of those agglomerates, making them more likely to break up in the turbulent airflow created during inhaler actuation when the particles are expelled from the inhaler and inhaled.
[0277] The compositions described herein may include additive substances (eg, in the form of discrete particles of a size comparable to that of the active particulates).
[0278] The additive may be an anti-adhesion material, which reduces inter-particle cohesion and further prevents fine particles from adhering to surfaces within the inhaler. The additive is advantageously an anti-friction agent or glidant, which improves the flow characteristics of the powder formulation within the inhaler. Additives used in this manner are not necessarily usually called anti-adhesion agents or anti-friction agents, but they have the effect of reducing inter-particle cohesion or improving powder flow. Therefore, additives are sometimes called force control agents (FCAs), and such additives typically result in better dose reproducibility and a higher fine particle fraction (FPF).
[0279] Thus, as used herein, additive substance or FCA refers to a substance whose presence on the surface of a particle can alter the surface adhesive and cohesive forces experienced by that particle in the presence of other particles and relative to the exposed surface of the particle. Generally, its function is to reduce both adhesive and cohesive forces.
[0280] Reducing the tendency of particles to bond strongly either to one another or to the device itself not only reduces powder clumping and adhesion, but also promotes improved flow characteristics. This reduces variability in the amount of powder metered for each dose and improves release of the powder from the device, thereby increasing dose reproducibility. It also increases the likelihood that the active agent exiting the device will reach the subject's lower lungs.
[0281] The use of such additive substances is disclosed, for example, in WO1996 / 023485 and WO1997 / 003649.
[0282] It is also known that micronized drug particles and additive substances may be vigorously co-milled to produce composite particles. As disclosed in a prior patent application published as WO2002 / 043701, this co-milling can improve dispersibility. Furthermore, a prior patent application published as WO2002 / 000197 discloses that fine particles of an excipient substance can be vigorously co-milled with an additive substance to prepare composite excipient particles, to which active fine particles and, optionally, coarse carrier particles can be added. This has also been shown to improve dispersibility.
[0283] At least two methods for processing active and additive particles can be used in the present disclosure. First, there are compression-type processes, such as Mechanofusion and Cyclomix, and related methods, such as Hybridizer or Nobilta. As the name suggests, Mechanofusion is a dry coating process designed to mechanically fuse a first material onto a second material. The first material is generally smaller and / or softer than the second material. The principles behind the Mechanofusion and Cyclomix processes differ from those of other comminution technologies in that they involve a special interaction between the internal elements and the container wall and are based on the supply of energy through controlled, substantial compression forces.
[0284] The active and additive particles are fed into a mechanofusion-driven vessel (e.g., Mechanofusion System (Hosokawa Micron Corporation)), where they are centrifugal-forced against the vessel's inner wall. The inner wall and the curved inner element together form a gap, or nip, where the particles are pressed against each other. The powder is compressed between the fixed gap in the drum wall and the curved inner element due to the high relative velocity between the drum and the element. As a result, the particles are subjected to very high shear forces and very strong compressive stresses while trapped between the inner drum wall and the inner element (which has a greater curvature than the inner drum wall). The particles are locally heated, softened, broken, deformed, flattened, and pressed against each other with enough energy to coat the additive particles around the active particles and form a coating. The energy is generally sufficient to break down agglomerates, and some size reduction of both components may occur. While the coating may not be complete, the deagglomeration of the particles during the process ensures that the coating is substantially complete and may cover a large portion of the particle's surface.
[0285] Such Mechanofusion and Cyclomix processes achieve effective mixing and application of additives to the surfaces of the active particles by applying forces strong enough to separate individual particles of the active material and to break up tightly bound agglomerates of the active particles.
[0286] A particularly desirable aspect of the described processing method is that the additive material is deformed during mechanofusion and can be applied or fused to the surface of the active particles. In reality, however, this compression process results in little or no reduction in drug particle size, especially when the drug particles are already in micronized form (i.e., less than 10 μm). The only physical change that can be observed is plastic deformation of the particles to a more rounded shape.
[0287] Further processing techniques include those described by R. Pfeffer et al., "Synthesis of engineered particulates with tailored properties using dg particle coating," Powder Technology 117 (2001) 40-67. Such techniques include processes using a Mechanofusion machine, a Hibidizer machine, a Theta Composer, a magnetically assisted impaction process, and a rotating fluidized bed coater. The Cyclomix process can also be used.
[0288] This technique involves compressing a mixture of particles of dispersion and particles of a pharmaceutically active agent in a nip formed between two parts of a machine that can be used to provide the necessary mechanical energy (as in Mechanofusion and Cyclomix devices). Several processing methods are described below.
[0289] Mechanofusion: This dry coating method is designed to mechanically fuse a first material onto a second material, which is generally smaller and / or softer than the second material. The principle of Mechanofusion and Cyclomix processing differs from other processing techniques in that it involves a special interaction between the internal elements and the container wall, and is based on the delivery of energy through controlled, substantial compressive forces.
[0290] The active fine particles and dispersant particles are fed into a mechanofusion-driven vessel, where they are centrifugal-forced against the vessel's inner wall. The powder is compressed between a fixed gap in the drum wall and a curved internal element due to the high relative velocity between the drum and the element. The internal wall and the curved element together form a gap or nip where the particles are pressed against each other. As a result, the particles are subjected to very high shear forces and very strong compressive stresses while trapped between the drum's inner wall and the internal element (which has a greater curvature than the drum's inner wall). The particles are locally heated, softened, broken, deformed, flattened, and collide violently with each other with enough energy to form a coating of dispersant particles around the core particles. The energy is generally sufficient to break down agglomerates, and some size reduction of both components may occur. Embedding and fusion of the dispersant additive particles into the active particles may occur, which may be facilitated by the relative differences in hardness (and possibly size) of the two components. Either the outer vessel or the inner element can rotate to provide relative motion. The gap between their surfaces is relatively small, typically less than 10 mm, and can be less than 5 mm or even less than 3 mm. This gap is fixed, resulting in better control of the compression energy than is achieved with some other forms of milling, such as ball mills and media mills. Furthermore, the lack of influence of the grinding media surface generally minimizes wear and resulting contamination. Rotation speeds can range from 200 to 10,000 rpm. A scraper may be present to break up any stuck material that accumulates on the vessel surface. This is particularly advantageous when using fine, sticky starting materials. Local temperature can be controlled using heating / cooling devices integrated into the drum vessel wall. The powder may be recirculated through the vessel.
[0291] Cyclomix method (Hosokawa Micron): The Cyclomix consists of a stationary conical vessel with a high-speed rotating shaft and paddles that move close to the wall. The high rotational speed of the paddles propels the powder toward the wall, resulting in the mixture being subjected to very high shear and compressive forces between the wall and the paddle. This effect, similar to that in mechanofusion described above, can be sufficient to locally heat, soften, break, deform, flatten, and coat particles of dispersant around the active particles to form a coating. The energy is sufficient to break down agglomerates and, depending on the conditions and the size and nature of the particles, can also result in some size reduction of both components.
[0292] Hybridizer method: This is a dry process that can be described as embedding or filming one powder onto another. Active particles and fine or ultrafine particles of dispersant are fed into a conventional high-shear mixer premixing system to form a coherent mixture. This powder is then fed into a hybridizer. The powder is impacted by the blades of a high-speed rotor within a stationary container, where it undergoes ultra-high-speed impact, compression, and shear, and is then recirculated within the container. The active and additive particles collide with each other. Typical rotation speeds are in the range of 5,000 to 20,000 rpm. The relatively flexible dispersant particles are subjected to sufficient impact force to soften, break, deform, flatten, and form a coating around the active particles. Some embedding into the surface of the active particles may also occur.
[0293] A second type of process mentioned in the prior art is impact milling processes, such as ball milling, jet milling, and the use of homogenizers.
[0294] Ball milling is the milling method used in many of the prior art processing methods. Centrifugal ball milling and planetary ball milling can be used.
[0295] Jet mills are capable of reducing solids to particle sizes in the low micron to submicron range. The milling energy is provided by a gas stream from horizontal milling air nozzles. Particles in the fluidized bed created by the gas stream are accelerated toward the center of the mill where they collide with slower-moving particles. The gas stream and the particles carried within it create intense turbulence, and as the particles collide with each other, they are milled.
[0296] In a high-pressure homogenizer, the particle-laden fluid is forced through a valve at high pressure, creating high shear and turbulent conditions. Suitable homogenizers include the EmulsiFlex high-pressure homogenizer, which is capable of pressures up to 4000 bar, the Niro Soavi high-pressure homogenizer (capable of pressures up to 2000 bar), and the Microfluidics Microfluidizer (maximum pressure 2750 bar).
[0297] Alternatively, the milling can use a high energy media mill or an agitator bead mill, such as a Netzsch high energy media mill or a DYNO mill (Willy A. Bachofen AG, Switzerland).
[0298] All of these processes produce high energy impacts between the media and the particles or between the particles themselves. In practice, these processes are good for preparing very small particles, but it has been found that ball mills, jet mills, and homogenizers are not as effective as compaction-type processes in providing improved dispersion of the resulting drug powder. The impact processes described above are believed to be less effective than compaction-type processes in producing a coating of additive material on each particle.
[0299] For purposes of this disclosure, all forms of co-milling are encompassed, including methods similar to or related to all of the methods described above. For example, methods similar to mechanofusion are encompassed, such as those utilizing one or more ultra-high shear rotors (i.e., 2000-50,000 rpm) in which blades or other elements sweep across the interior surface of a vessel having a small gap (i.e., 0.1 mm-20 mm) between the wall and the blade. Also encompassed are conventional methods (such as those described in WO 2002 / 043701) involving co-milling an active material with an additive material. These methods result in composite active particles containing ultrafine active particles bearing a certain amount of additive material on their surface.
[0300] In the past, jet milling was considered an unattractive method for micronizing active and additive particles in the preparation of powder formulations to be dispensed using passive devices: Collisions between particles in a jet mill are somewhat uncontrolled, and therefore, those skilled in the art believed that this technique was unlikely to impart the desired coating of additive material to the surface of the active particles.
[0301] Furthermore, unlike the situation with compression-type processes such as Mechanofusion and Cyclomixing, it was believed that jet milling could result in segregation of the powder components, with the result that the finer particles that would be most effective could escape the process. In contrast, it is clear how techniques such as Mechanofusion could result in the desired coating.
[0302] Jet milling has been shown to be an attractive process for micronizing active and additive particles, particularly for preparing powder formulations to be used in active devices (see the disclosure of the prior patent application published as WO 2004 / 001628, which is incorporated herein by reference in its entirety). In another embodiment, the additive material may be in the form of particles that adhere to the surfaces of the active and carrier particles. Such additive material may be fused to the surfaces of the active and carrier particles.
[0303] The carrier particles can be any acceptable inert excipient material or combination of materials. For example, carrier particles frequently used in the prior art can be composed of one or more materials selected from sugar alcohols, polyols, and crystalline sugars. Other suitable carriers include inorganic salts such as sodium chloride and calcium carbonate, organic salts such as sodium lactate, and other organic compounds such as polysaccharides and oligosaccharides. Advantageously, the carrier particles include polyols. In particular, the carrier particles can be particles of crystalline sugars, such as mannitol, dextrose, or lactose. In some embodiments, the carrier particles are trehalose particles. The carrier particles can be composed of lactose.
[0304] The additive may comprise a metal stearate or a derivative thereof, such as sodium stearyl fumarate or sodium stearyl lactate. Advantageously, the additive comprises a metal stearate, such as zinc stearate, magnesium stearate, calcium stearate, sodium stearate, or lithium stearate. The additive may comprise magnesium stearate, such as vegetable magnesium stearate, or any form of commercially available metal stearate, which may be of vegetable or animal origin and may also contain other fatty acid components, such as palmitate or oleate.

The sample was transferred to a 500 mL flask and diluted to approximately 24 mcg / mL. Approximately 250 mL of the diluted solution was then sonicated for 10-20 minutes. The content uniformity of Compound I in the diluted sample was then determined by HPLC. This process was repeated for a total of 10 samples.
[0321] General Procedure for Measuring APSD, MMAD, FPM, and FPF Preparation of cup coating agent The cup coating was prepared by mixing 150 mL of a mixture of Brij® 35, ethanol, and glycerol with 850 mL of ethanol.
[0322] NGI Procedure The cup coating agent was prepared, and the NGI was assembled. The collection cup was then coated with the cup coating agent and then allowed to dry. A PALL® A / E 76 mm filter was placed inside the backup filter and attached to the NGI. Approximately 15 mL of diluent was added to the pre-separator insert. The flow rate was set to 90 L / min, and the capsule was punctured. A single dose was released into the NGI by activating the time-controlled solenoid valve for 2.70 seconds. Sample diluent was added (10 mL for the 0.2 mg and 2.0 mg doses, and 20 mL for the 4.0 mg dose), and the collection cup was agitated on an NGI Gentle Rocker for 10 minutes. 40 mL of sample diluent was added to the induction port and shaken for 1 minute. 50 mL of sample diluent was added to the pre-separator and shaken for 1 minute. The backup filter was transferred to a crystallizing dish containing 20 mL of sample diluent and then sonicated for 5 minutes. The capsules from each run were then transferred to a 20 mL flask and sample diluent was added. The suspension was then shaken and sonicated until completely dissolved. The resulting solution was allowed to equilibrate under ambient conditions and then brought to volume. Each single dose of RS01 was placed in an individual plastic bag and 20 mL of recovery solution was added. The bag was shaken by hand for 1 minute and filtered prior to HPLC analysis.
[0323] General Procedure for Measuring the Delivered Dose of Compound I A castellated fixed volume dose unit sampling apparatus (DUSA) was assembled and attached to a backup filter. The DUSA used PALL® A / E 47 mm filter paper, and the backup filter used a PALL® A / E 76 mm filter. The solenoid timer was then primed and the flow rate adjusted to 90 L / min. The pre-sample weight of the device was recorded, and the inhaler was activated. Two doses were released into the DUSA by activating the time-controlled solenoid valve. The post-sample weight of the device was then recorded, and the exhaust bung was inserted into the exhaust port. Sample diluent (50 mL) was introduced into the DUSA through the mouthpiece adapter, and the DUSA was placed on an orbital shaker at 250 shakes per minute for 5 minutes. The capsule was dissolved in the diluent, and the drug retained in the device was recovered by washing with the diluent. Dilutions were performed using 4 mg capsules. All samples were filtered through disposable 0.2 μm PTFE syringeless filters with polypropylene housings into HPLC vials and analyzed by HPLC.
[0324] Example 1: Formulations containing Compound I Mixture 1 (2 kg scale) A 1 wt% magnesium stearate excipient preblend, i.e., lactose:MgSt, was prepared by blending 10% fines (3961.3 g) with magnesium stearate (38.8 g). An 88.0 wt% magnesium stearate API preblend (12.0 wt% magnesium stearate), i.e., API:MgSt, was prepared by blending Compound I (35.4 g) with magnesium stearate (4.8 g). Approximately 1977.1 g of the lactose:MgSt preblend was blended with 22.8 g of the API:MgSt preblend. The resulting mixture was then homogenized in a TRV blender at 500 rpm for 14 minutes to yield a 1.0 wt% API bulk powder formulation (Mix 1). Prior to testing, Mix 1 bulk powder was transferred to a plastic ChargeBag®.
[0325] The content uniformity and drug content measured for the bulk powder of Blend 1 are shown in Table 1.
[0326] [Table 3]
[0327] mixture 1a To investigate the effect of static charge on bulk drug content and content uniformity, Blend 1 was reprocessed in a stainless steel container according to the following procedure: During transfer to the stainless steel container, large agglomerates of Blend 1 were observed, suggesting the need for an additional co-milling step in the manufacture of Compound I formulations.
[0328] The Blend 1 bulk powder was transferred to a clean, hermetically sealed GMP stainless steel container (160 mm x 160 mm) and reprocessed by co-milling at 1000 rpm. The mixture was then homogenized by TRV mixing at 1000 rpm for 7 minutes to yield the formulation (Blend 1a). The content uniformity and drug content measured for Blend 1a are shown in Table 2. These data indicate that the co-milling step in the manufacture of Blend 1a improved the content uniformity. However, the drug content of Blend 1a remained low.
[0329] [Table 4]
[0330] Example 2: Low-dose formulation of Compound I (0.2 mg) To further investigate the effect of static charge within the formulation of Compound I, a rest period was introduced into the manufacturing process according to the following procedure: Additionally, the magnesium stearate content in the API:MgSt preblend was reduced to investigate its potential impact on the formulation of Compound I.
[0331] Mixture 2a (with co-grinding) (0.4 kg scale) A 0.9 wt% magnesium stearate excipient preblend, i.e., lactose:MgSt, was prepared by blending 10% fines (3962.4 g) of lactose with 37.6 g of magnesium stearate. A 6.5 wt% magnesium stearate API preblend, i.e., API:MgSt, was prepared by blending Compound I (69.9 g) with 4.9 g of magnesium stearate. In a subsequent step, 395.1 g of lactose:MgSt preblend and 4.8 g of API:MgSt preblend were processed into a 1 L TRV bowl using a U5 Comil® equipped with a 457 mcm sieve at 1000 rpm. The resulting mixture was then homogenized in a TRV blender at 1209 rpm for 4 minutes to yield a 1 wt% API bulk powder formulation (Mixture 2a). The blend 2a bulk powder was transferred to a clean, sealed GMP stainless steel container (160 mm x 160 mm), followed by a rest period (20, 40, or 60 hours) before capsule filling. For a target dose of 0.2 mg, 20 mg of blend 2a bulk powder was manually filled into capsules.
[0332] The composition of the resulting 0.2 mg product is shown in Table 3.
[0333] [Table 5]
[0334] The content uniformity and drug content measured for the Blend 2a bulk powder are shown in Table 4, along with the aerodynamic particle size distribution measured for the Blend 2a capsules.
[0335] Mixture 2b (without co-milling) (0.4 kg scale) A 0.9 wt% magnesium stearate excipient preblend, i.e., lactose:MgSt, was prepared by blending lactose (10% fines (3962.4 g)) with magnesium stearate (37.6 g). A 6.5 wt% magnesium stearate API preblend, i.e., API:MgSt, was prepared by blending Compound I (69.9 g) with magnesium stearate (4.9 g). Approximately 395.3 g of the lactose:MgSt preblend was blended with 4.8 g of the API:MgSt preblend. The resulting mixture was then homogenized in a TRV blender at 1209 rpm for 4 minutes to yield a 1 wt% API bulk powder formulation (Mix 2b). The Mix 2b bulk powder was transferred to a clean, sealed GMP stainless steel container (160 mm x 160 mm) followed by a rest period (20, 40, or 60 hours) before capsule filling. For a target dose of 0.2 mg, 20 mg of blend 2b bulk powder was hand-filled into capsules.
[0336] The content uniformity and drug content measured for Blend 2b bulk powder are shown in Table 4, along with the aerodynamic particle size distribution measured for Blend 2b capsules. A comparison of the standard deviations for Blend 2a (co-milled) and Blend 2b (no co-milling) from the individual stage profiles of the aerodynamic particle size distribution is shown in Table 5.
[0337] [Table 6]
[0338] As can be seen in Table 4, there was a decrease in variability in content uniformity of Blend 2b bulk powder after the 60-hour settling period compared to the 20-hour and 40-hour settling periods, as evidenced by the decrease in RSD. Furthermore, the use of a co-milling process in the manufacture of formulations containing Compound I resulted in higher drug delivery efficiencies, as estimated by the average FPF. Also, compared to Table 1, the data in Table 4 suggest that the use of stainless steel equipment, co-milling, settling period, and lower magnesium stearate concentration in the API:MgSt preblend resulted in higher drug loads for formulations containing Compound I.
[0339] [Table 7]
[0340] As shown in Table 5, Mix 2b exhibited less variability in standard deviations from the individual APSD stage profiles after a 60-hour rest period than after a 20-hour or 40-hour rest period. Also shown in Table 5, Mix 2a exhibited less variability after a 40-hour and 60-hour rest period than after a 20-hour rest period. Furthermore, for the 40-hour and 60-hour rest periods, the variability was less for Mix 2a than for Mix 2b.
[0341] Example 3: High dose formulations of Compound I (2.0 mg and 4.0 mg) Mixture 3 (0.4 kg scale) A 0.6 wt% magnesium stearate excipient preblend, i.e., lactose:MgSt, was prepared by blending 6% fines (3976.8 g) with magnesium stearate (23.3 g). A 6.5 wt% magnesium stearate API preblend, i.e., API:MgSt, was prepared by blending Compound I (69.9 g) with magnesium stearate (4.9 g). In a subsequent step, a U5 Comil® equipped with a 457 mcm sieve was used to process 356.0 g of the lactose:MgSt preblend and 44.0 g of the API:MgSt preblend into a 1 L TRV bowl at 1000 rpm to prepare a blend. The resulting blend was then homogenized in a TRV blender at 2392 rpm for 4 minutes to obtain a 10 wt% API bulk powder formulation (Blend 3). The Blend 3 bulk powder was transferred to a clean, sealed GMP stainless steel container (160 mm x 160 mm), followed by a rest period (20 or 60 hours) before capsule filling. Size 3 HPMC capsules were manually filled with 20 mg of Blend 3 bulk powder for a target dose of 2.0 mg, and with 40 mg of Blend 3 bulk powder for a target dose of 4.0 mg. The compositions of the resulting 2.0 mg and 4.0 mg products are shown in Table 6.
[0342] [Table 8]
[0343] The content uniformity, drug content, and aerodynamic particle size distribution measured for the bulk powder, 20 mg capsules, and 40 mg capsules are shown in Table 7. The standard deviations from the individual stage profiles of the aerodynamic particle size distribution for the three capsules of the blend are shown in Table 8.
[0344] [Table 9]
[0345] Improved uniformity of Blend 3 bulk powder was observed after the 60-hour settling period compared to the 20-hour settling period, as evidenced by a decrease in RSD. Furthermore, Blend 3 was filled into both 20 mg capsules (2.0 mg Compound I) and 40 mg capsules (4.0 mg Compound I) and showed an increase in mean fine particle fraction after the 60-hour settling period compared to the 20-hour settling period. In addition, the improved drug content over Blend 1 and Blend 1a (Tables 1 and 2) further supports the need for stainless steel equipment, co-milling, and a settling period to produce suitable formulations of Compound I, and supports the need for a lower concentration of magnesium stearate in the API:MgSt preblend to produce formulations containing Compound I, magnesium stearate, and lactose suitable for clinical trials.
[0346] Thus, the improved uniformity of Blend 3, as inferred from content uniformity (Table 7), and the improved drug content of Blend 3 led to clinical trials of formulations comprising Compound I, lactose, and magnesium stearate. In other words, the methods for preparing dry powder pharmaceutical formulations of Compound I disclosed herein and the pharmaceutical formulations of Compound I, lactose, and magnesium stearate disclosed herein resulted in formulations comprising Compound I that were suitable for clinical trial investigation. Prior to this discovery, clinical studies of previous formulations comprising Compound I, lactose, and magnesium stearate could not be conducted due to both the lack of uniformity of Blend 1, as inferred from low content uniformity, and the low drug content (Table 1).
[0347] [Table 10]
[0348] Table 8 shows that there is less variability (as indicated by the lower standard deviation) from the 60 hour rest period than from the 20 hour rest period for both the 20 mg and 40 mg capsules of Blend 3.
[0349] Mixture 4 (2 kg scale) A 0.6 wt% magnesium stearate excipient preblend, i.e., lactose:MgSt, was prepared by blending 6% fines (3976.6 g) with magnesium stearate (23.2 g). A 6.5 wt% magnesium stearate API preblend, i.e., API:MgSt, was prepared by blending Compound I (243.3 g) with magnesium stearate (16.9 g). In a subsequent step, 1792.3 g of lactose:MgSt preblend and 175.9 g of API:MgSt preblend were processed into a 5 L TRV bowl at 1000 rpm using a U5 Comil® equipped with a 457 mcm sieve to prepare a blend. The resulting blend was then homogenized in a TRV blender at 1385 rpm for 7 minutes to obtain a 10 wt% API bulk powder formulation (Blend 4). The Blend 4 bulk powder was transferred to a clean, sealed GMP stainless steel container (160 mm x 160 mm), followed by a 60-hour rest period before capsule filling. Size 3 HPMC capsules were hand-filled with 20 mg of Blend 4 bulk powder for a target dose of 2.0 mg and with 40 mg of Blend 4 bulk powder for a target dose of 4.0 mg.
[0350] The compositions of the resulting 2.0 mg and 4.0 mg products are shown in Table 9.
[0351] [Table 11]
[0352] Content uniformity and drug content are shown in Table 10. Fine particle mass, fine particle fraction, and mass median aerodynamic diameter measured for the 2 mg and 4 mg capsules are shown in Tables 11 and 12, respectively. For comparison, NGI FPF data for commercially available DPI products are summarized in Table 13. For comparison, MMAD values for commercially available DPI products are summarized in Table 14. Delivered dose data for the 2 mg and 4 mg formulations of Compound I are shown in Figures 2 and 3, respectively.
[0353] [Table 12]
[0354] [Table 13]
[0355] [Table 14]
[0356] The results in Table 11 (2.0 mg Compound I) and Table 12 (4.0 mg Compound I) demonstrate that Compound I formulations exhibit favorable drug delivery efficiencies, as evidenced by FPFs of approximately 73-78%. Tables 11 and 12 also demonstrate that low MMAD values (1.8-2.0 μm) are achieved when Compound I formulations are aerosolized. These data also suggest that drug delivery efficiencies are highly reproducible for Compound I formulations stored at accelerated conditions for periods including up to 24 months.
[0357] [Table 15-1] [Table 15-2]
[0358] Additionally, the FPF data obtained from formulations containing Compound I (2.0 mg, Table 11 and 4.0 mg, Table 12) are significantly higher than those reported for a range of commercially available dry powder inhalation formulations (Table 13) (Demoly et al., Respir. Med. 2014, 108, 1195).
[0359] [Table 16]
[0360] Furthermore, the MMAD values obtained from formulations containing Compound I (2.0 mg, Table 11 and 4 mg, Table 12) are lower than those reported for commercially available dry powder inhalation formulations (Table 14) (Derendorf et al., Eur. Respir. J. 2006, 28, 1042).
[0361] Furthermore, both the 2 mg and 4 mg formulations containing Compound I exhibit high drug delivery efficiency, as shown by the delivered dose data in Figures 2 and 3, respectively. As shown in Figure 2, the average delivered dose for the 2 mg formulation containing Compound I is approximately 1.6 mg, or 80%. As shown in Figure 3, the average delivered dose for the 4 mg formulation containing Compound I is approximately 3.47 mg, or 87%. All individual results are well within ±20% of the average delivered dose for both the 2 mg and 4 mg formulations. Furthermore, the maximum and minimum deviations from the average delivered dose are within 10% and 16%, respectively, for the 2 mg formulation, and within 9% and 12%, respectively, for the 4 mg formulation. Therefore, the formulations containing Compound I demonstrate excellent drug delivery efficiency and reproducibility, independent of storage time and conditions.
[0362] Example 4: Animal Studies of Compound I Formulations A lactose / MgSt-based formulation of Compound I was evaluated in a 13-week inhalation toxicity study using a rat model.
[0363] The results of the toxicity studies are shown below in Table 15. No treatment effects were observed on clinical signs, body weight, food intake, ophthalmology, blood chemistry, urinalysis, or gross pathology. A NOAEL was assigned to the highest dose tested (11.9 mg / kg / day).
[0364] [Table 17]
[0365] A lactose / MgSt-based formulation of Compound I was evaluated in a 13-week inhalation toxicity study in the NHP model. The corresponding results are shown in Table 16 below. No treatment-related effects were observed on clinical signs, body weight, food intake, ophthalmology, blood chemistry, urinalysis, or gross pathology. A NOAEL was assigned to the highest dose tested (7.9 mg / kg / day).
[0366] [Table 18]
[0367] The results of the margin of safety study for the lactose / MgSt-based formulation of Compound I are shown below in Table 17. These results suggest that significant systemic and pulmonary safety margins are established for the highest daily (4 mg BID) pharmacologically active dose.
[0368] [Table 19]
[0369] Example 5: Phase 1 Clinical Trial of Formulations of Compound I A summary of the recruitment status of the Phase 1 clinical trial is shown in Table 18 below. Capsules filled with Mixture 2a were used to achieve a target dose of 0.6 mg of Compound I (3 x 0.2 mg capsules). Capsules filled with Mixture 4 were used to achieve target doses of 2.0 mg, 4.0 mg, 6.0 mg, 8.0 mg, and 12.0 mg of Compound I (1 x 2.0 mg capsule, 1 x 4.0 mg capsule, 3 x 2.0 mg capsules, 2 x 4.0 mg capsules, and 3 x 4.0 mg capsules, respectively). Twice-daily dosing (BID) was achieved by repeating the previous regimen. For example, an 8.0 mg BID dosing regimen is achieved by administering 2 x 4.0 mg capsules twice.
[0370] [Table 20]
[0371] Specific FeNO reduction data from Figure 5 are highlighted in Table 19 below. For comparison, a FeNO reduction of greater than 20% is defined as clinically significant (Am. J. Respir. Crit. Care Med. 2011, 184, 602). These results suggest that formulations containing Compound I at doses of 2.0 mg QD or greater delivered in a single capsule provide clinically meaningful FeNO reductions.
[0372] [Table 21]
[0373] Subjects in Figure 7 with FeNO levels <25 ppb on the last day of dosing (Day 10) are highlighted in Table 20 below. These results further suggest that formulations containing Compound I at doses of 2.0 mg QD or greater delivered in a single capsule result in clinically meaningful reductions in FeNO.
[0374] [Table 22]
[0375] A summary of adverse events from the Phase 1 clinical trial of Compound I (Figure 4) is shown in Table 21. No serious or serious adverse events were observed, but only mild / moderate severity adverse events were observed and were typically "unlikely related." No clinically meaningful changes were observed, as judged by the investigator, in hematology, biochemistry, or urinalysis parameters, including those affected by JAK inhibition (e.g., WBC, platelets, reticulocytes, APTT, lipids, absolute neutrophil count). No clinically meaningful changes related to treatment were observed in cardiovascular endpoints (i.e., ECG and vital signs).
[0376] [Table 23]
[0377] The FeNO reduction rate data compared to the safety margin are shown below in Table 22. The data suggest that the 4.0 mg BID dose is most likely to achieve clinical efficacy in Phase 2 clinical trials.
[0378] [Table 24]
[0379] A comparison of FeNO reduction data obtained under similar conditions using formulations of Compound I versus formulations containing the JAK1 inhibitors GDC-0214 and GDC-4379 is shown in Table 23 below. A similar comparison between formulations containing Compound I and formulations containing TD-8236 (a pan-JAK inhibitor) is shown in Figure 8, with corresponding data highlighted in Table 24. Note that patients receiving formulations containing Compound I, GDC-0214, and GDC-4379 were characterized by mild asthma and were not receiving ICS therapy. Patients receiving TD-8236 were characterized by moderate to severe asthma.
[0380] The data suggest that clinically meaningful FeNO reductions can be achieved with lower API doses and fewer capsules using the Compound I formulation compared to the GDC-0214 and GDC-4379 formulations. The data also demonstrate that in patients with moderate to severe asthma, the Compound I formulation demonstrates significantly greater FeNO reductions at a dose administered in a single capsule compared to the TD-8236 formulation.
[0381] [Table 25]
[0382] [Table 26]
[0383] Specific FeNO reduction data from Figure 9 are highlighted in Table 25 below. These results suggest that clinically meaningful FeNO reductions are achieved in patients with moderate to severe asthma using ICS / LABA background therapy after administration of a 4 mg BID regimen of a formulation containing Compound I. Each dose was delivered via a single capsule over a 10-day period. More specifically, subjects with pre-dose FeNO levels of 33-280 ppb on Day 1 demonstrated a greater than 20% reduction by Day 10, and subjects with pre-dose FeNO levels ranging from 33-118 ppb on Day 1 recorded levels below 25 ppb by Day 10.
[0384] [Table 27]
[0385] The specific FeNO reduction data from Figure 10 is highlighted below in Table 26, where greater reductions in FeNO were obtained in subjects with elevated baseline blood eosinophil levels.
[0386] [Table 28]
[0387] The specific FeNO reduction data from Figure 11 are highlighted below in Table 27. These results further suggest that formulations containing Compound I at a dose of 4.0 mg BID provide clinically meaningful FeNO reductions in patients with moderate to severe asthma using ICS / LABA background therapy.
[0388] [Table 29]
[0389] Pharmacokinetic parameters at Day 10 for Parts 2 and 3 of Phase I are summarized in Table 28 below. In Part 2, subjects with mild asthma not receiving ICS therapy received four different dose regimens over 10 days. Each separate cohort consisted of six subjects receiving active treatment and two subjects receiving a matching placebo. Blood samples were collected to measure Compound I plasma concentrations. The resulting data were used to determine PK parameters at Day 10, representing the day the final dose was administered. Dose regimens ranging from 2 mg QD to 8 mg BID were considered pharmacologically active, as evidenced by clinically meaningful placebo-corrected mean FeNO changes from pre-dose on Day 1 to Day 10. 0.6 mg QD was identified as the lowest active dose at which the placebo-corrected mean FeNO change was below the 20% threshold used to determine clinical relevance.
[0390] In Part 3, subjects with moderate to severe asthma treated with ISC / LABA background therapy (17 active, 6 placebo) received a single-dose regimen (4 mg BID) for 10 days. Blood samples were collected to measure plasma KN-002 concentrations. Pharmacokinetic parameters were determined on Day 10, representing the day the final dose was administered.
[0391] [Table 30-1] [Table 30-2]
[0392] Sputum and serum inflammatory biomarkers on day 10 are shown in Table 29 below. In Part 3, sputum samples collected by sputum induction were evaluated according to the European Respiratory Society guidelines (Paggiaro, et al., Eur. Respir. J. 2002, 20:Suppl. 37, 3s). Subjects were randomly assigned to a sputum-producing group and a non-sputum-producing group, with a minimum goal of approximately 50% of subjects being able to provide adequate sputum samples at screening. Subjects in the sputum-producing group underwent a second sputum induction after 10 days of treatment with 4 mg Compound I BID or placebo. Differential cell counts (DCC) were performed on samples deemed appropriate according to standard procedures, and patients with evaluable baseline (screening) and post-treatment samples at day 10 (or day 11 if day 10 was not appropriate) were included in analyses including individual and mean absolute eosinophil counts and differential eosinophil percentages.
[0393] In the sputum-producing group, six Compound I (active) subjects and two placebo subjects were identified with adequate baseline and post-treatment sputum samples. The resulting data were used to determine the percent change from baseline, mean percent change from baseline, and placebo-adjusted mean percent change from baseline (Compound I vs. placebo). As reported below, improvements (reductions) from baseline were observed in both individual and mean absolute eosinophil counts and eosinophil differential percentages in all active-treated subjects, whereas no improvement was observed in either parameter in placebo subjects. The placebo-adjusted mean percent change from baseline demonstrated similar improvements in absolute eosinophil counts and eosinophil differential percentages. At baseline, all subjects had eosinophil differential percentages greater than 3%, indicating active eosinophilic inflammation. By day 10, 66% (4 / 6) of active treatment subjects had improved to <3% eosinophils, and 50% (3 / 6) were below the more stringent decision threshold of 1.9% (Reddel et al., Am. J. Respir. Crit. Care Med. 2009, 180, 59). Placebo subjects showed no improvement. These findings support the pharmacodynamic involvement of Compound I at its site of action (the airway) and demonstrate a clinically meaningful effect on eosinophilic inflammation after 10 days of treatment.
[0394] Whole blood hematology samples were collected from all patients on Day 1 (baseline) and Day 10 before dosing. Parameters including absolute whole blood eosinophil count and eosinophil differential percentage were determined, and the resulting data were used to determine the percent change from baseline, mean percent change from baseline, and placebo-corrected mean percent change from baseline (Compound I vs. placebo). As reported below, improvements (decreases) from baseline were observed in 83% (5 / 6) of active treatment subjects, with only minor decreases observed in both placebo treatment subjects. Decreases (improvements) in mean absolute eosinophil count and mean eosinophil differential percentage were observed in active treatment-treated subjects, and the placebo-corrected mean percent change from baseline values similarly reflected improvements in this marker of eosinophilic inflammation.
