[Technical Field]

[0001] This application claims the benefit of U.S. Provisional Patent Application Serial No. 63 / 486,013, filed February 20, 2023, the disclosure of which is incorporated herein by reference in its entirety.

[0002] Statement Regarding Electronic Filing of Sequence Listings The XML sequence listing, file name "1458-5WO_ST26.xml", size 1,557,299 bytes, created on February 19, 2024, and attached to this application, is incorporated herein by reference in its entirety.

[0003] [Technical field] The present invention relates to hyaluronidase particles, compositions comprising the hyaluronidase particles, and methods of making and using the hyaluronidase particles. [Background technology]

[0004] Subcutaneous injections offer a flexible and effective route of drug administration, in which pharmaceuticals are injected into the tissue layer between the skin and muscle. Subcutaneous injections are advantageous in that they are an inexpensive and painless method of parenteral administration with a low risk of systemic infection and a slow absorption rate, thereby providing long-term efficacy of the injected drug. However, fluids injected subcutaneously remain largely at the injection site and slowly disappear over several hours to several days. Injecting large volumes (e.g., more than about 2 mL) can result in fluid retention and / or swelling at the injection site, which can cause local side effects such as pain, irritation, and / or skin damage. For this reason, subcutaneous injections are typically limited to small doses, e.g., volumes less than about 2 mL.

[0005] Hyaluronidase is a family of enzymes, particularly endoglycosidases, that can degrade hyaluronic acid and, in some cases, other glycoproteins, such as chondroitin and chondroitin sulfate. Hyaluronidases are present in organs, such as the testes, spleen, and liver, and in body fluids, such as tears and blood. Hyaluronidases exist in three distinct classes: mammalian (or vertebrate), bacterial, and leech / bloodworm. Within the mammalian class, the human genome contains six known genes encoding hyaluronidase-like sequences. Purified human hyaluronidases, such as testicular hyaluronidase PH-20 or ovine hyaluronidase, such as ovine PH-20, are commonly used for medical and experimental purposes.

[0006] Hyaluronidase in aqueous solution has been used subcutaneously to alter tissue permeability by degrading the subcutaneous hyaluronic acid network. By degrading the hyaluronic acid network in the subcutaneous space, subcutaneous administration of hyaluronidase in aqueous solution can disperse subcutaneously injected fluids more quickly than in the absence of hyaluronidase, thereby allowing large volumes of fluid to be administered. Hyaluronidase in aqueous solution has been approved by the US Food and Drug Administration (FDA) for use as an adjuvant in the rapid administration of large volumes of fluids of 1,000 mL or more or in the subcutaneous administration of other drugs. Hyaluronidase is typically administered as an aqueous solution before injecting a large volume of drug greater than 2 mL, or as a coformulation with a large volume of drug greater than 2 mL. Summary of the Invention [Problem to be solved by the invention]

[0007] Novel approaches for the administration of hyaluronidase and therapeutic agents are needed, particularly for subcutaneous and intradermal administration. [Means for solving the problem]

[0014] Another aspect of the present invention is directed to a method of improving tolerance and / or increasing absorption of a therapeutic agent upon subcutaneous, intramuscular, and / or intradermal administration to a subject, comprising subcutaneously, intramuscularly, and / or intradermally administering to the subject particles comprising hyaluronidase, the particles having a water content of less than about 15% by weight of the particles and / or a water activity of less than about 0.9, thereby improving tolerance and / or increasing absorption of the therapeutic agent upon subcutaneous, intramuscular, and / or intradermal administration to the subject. In some embodiments, the therapeutic agent is administered subcutaneously, intramuscularly, and / or intradermally to the subject before, during, and / or after subcutaneously, intramuscularly, and / or intradermally administering the particles to the subject.

[0015] It should be noted that aspects of the invention described herein with respect to one embodiment may be incorporated into a different embodiment, even if not specifically described therein.

[0032] Particles comprising hyaluronidase are provided according to embodiments of the present invention. In some embodiments, the particles comprising hyaluronidase further comprise an excipient (e.g., a stabilizer) and / or a therapeutic agent. The particles of the present invention may be solid and may have a water content of less than about 15% by weight of the particle and / or a water activity of less than about 0.9. In some embodiments, the particles have a water content of less than about 14%, less than about 13%, less than about 12%, less than about 11%, less than about 10%, less than about 9%, less than about 8%, less than about 7%, less than about 6%, less than about 5%, less than about 4%, less than about 3%, less than about 2%, less than about 1%, or less than about 0.5% by weight of the particle. In some embodiments, the particles of the present invention have a moisture content ranging from about 0%, about 0.5%, about 1%, about 2%, about 3%, or about 4% to about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, or about 15% by weight of the particle. In some embodiments, the particles of the present invention have a moisture content of less than about 10% by weight of the particle or less than about 5% by weight of the particle. In some embodiments, the particles of the present invention have a moisture content of about 0%, about 0.5%, about 1%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, about 11%, about 12%, about 13%, about 14%, or about 15% by weight of the particle. In some embodiments, the particles of the present invention have a water activity of less than about 0.9, less than about 0.85, less than about 0.8, less than about 0.75, less than about 0.7, less than about 0.65, less than about 0.6, less than about 0.55, less than about 0.5, less than about 0.45, less than about 0.4, less than about 0.35, less than about 0.3, less than about 0.25, less than about 0.15, less than about 0.1, less than about 0.05, or less than about 0.01. In some embodiments, the particles of the present invention have a water activity of less than about 0.5 or less than about 0.1. In some embodiments, the particles have a water activity ranging from about 0, about 0.01, about 0.05, about 0.1, about 0.15, about 0.2, about 0.25, about 0.3, about 0.35, about 0.4, or about 0.45 to about 0.5, about 0.55, about 0.6, about 0.65, about 0.7, about 0.75, about 0.8, about 0.85, or about 0.9.

[0033] Water content can be measured using methods known in the art, such as Karl Fischer titration and / or thermogravimetric analysis. In some embodiments, the water content of the particles of the present invention can be measured using a Mettler Toledo coulometric KF titrator. A sample containing the particles of the present invention is contacted with a solvent (e.g., methanol) to extract water from the sample, and the amount of water in the solvent is then measured (e.g., using a Mettler Toledo coulometric KF titrator). The amount of water present in the sample can be calculated by subtracting the water present in the solvent blank (the solvent before contact with the particles) from the measured water content of the solvent. For example, in some embodiments, about 15 mg to about 30 mg of particles of the present invention (e.g., in powder form) or a composition (e.g., a suspension) containing particles of the present invention is weighed into a glass vial in a dry box (relative humidity (RH) less than 20%), and about 1.5 mL of anhydrous methanol is added to the particles or composition to extract water from the sample. The methanol may then be injected into a titration cell (e.g., a Mettler-Toledo coulometric KF titrator), and the amount of water present in the methanol may be measured. The amount of water present in the particles or composition may then be calculated by subtracting the water present in a methanol blank from the measured water content of the methanol. In some embodiments, the water content of a suspension may be measured by directly injecting the suspension into a titration cell. In cases where no volatile components are present in the sample, or where no components are present in the sample that evaporate at a temperature similar to that of water, the water content may also be measured by loss on drying (e.g., using thermogravimetric analysis (TGA)).

[0034] Water activity is a measure of the chemical availability of water in a sample (e.g., in a particle of the present invention) and can quantify the amount of unbound water in the sample and / or how strongly water is bound to components in the sample (e.g., how strongly water is bound to a biological agent present in the particle). In some embodiments, water activity is measured by equilibrating a sample containing a particle of the present invention in a closed chamber and measuring the relative humidity of the headspace in the chamber. Alternatively, or in addition, water activity can be measured by correlating water activity with water content in a known system. To correlate water content with water activity, the water activity of a sample containing a particle of the present invention is determined by equilibrating the sample through a vapor phase with a known water activity (e.g., using a saturated salt solution or a dynamic vapor sorption instrument) and measuring the change in water content by Karl Fischer titration or measuring the change in mass to calculate the water activity of the sample. Thus, the water content and / or mass of a sample is measured before and after contact with the vapor phase, and the change is used to measure the water activity of the sample. In some embodiments, the water content and water activity of a single particle of the invention or a droplet containing a particle of the invention may be correlated by measuring the volume change of the single particle or droplet in response to contact (e.g., exposure to) a solvent with a known water activity or a gas with a known water activity, as described, for example, in Rickard, et al., Biophysical Journal, 2010;98(6):1075-84. The volume of a single particle or droplet is measured before and after contact with the solvent or gas, and the change in volume is used to measure the water activity of the sample.

[0035] In some embodiments, the particles of the present invention have a moisture content (e.g., total moisture content) of less than about 3% of the total particle mass. The particles may have a total moisture content of less than about 2.5%, less than about 2%, less than about 1.5%, less than about 1%, or less than about 0.5% of the total particle mass. In some embodiments, the total moisture content of the particles ranges from about 0%, about 0.1%, or about 0.5% to about 1%, about 1.5%, about 2%, about 2.5%, or about 3% of the total particle mass.

[0036] The particles of the present invention have a residue content of less than about 3% by weight of the particle (e.g., total particle mass). The particles may have a residue content of less than about 2.5%, less than about 2%, less than about 1.5%, less than about 1%, or less than about 0.5% by weight of the particle. In some embodiments, the residue content of the particles of the present invention ranges from about 0%, about 0.01%, about 0.05%, about 0.1%, or about 0.5% to about 1%, about 1.5%, about 2%, about 2.5%, or about 3% by weight of the particle.

[0038] The particles of the present invention may be spherical. In some embodiments, the particles may be amorphous. In some embodiments, at least a portion of the particles may be amorphous, and thus the particles may be partially amorphous. For example, all or a portion of the hyaluronidase may be amorphous in the particles of the present invention, but molecules (e.g., salts) within the hyaluronidase matrix may be crystalline in the particles of the present invention. The particles of the present invention may comprise one or more molecules of hyaluronidase, which may be the same or different from each other, and / or a matrix containing one or more molecules of hyaluronidase, which may be the same or different from each other, optionally wherein the hyaluronidase in the particles is amorphous.

[0039] In some embodiments, the particles of the present invention are in the form of a solid, e.g., a solid particle, and / or a powder. In some embodiments, the particles of the present invention are in the form of a solid when they are in the form of a powder (e.g., a dry powder, e.g., a powder in the absence of a liquid in which the powder is dispersed or suspended) and / or when they are present in a vehicle (e.g., a non-aqueous solvent and / or an aqueous solvent). In some embodiments, the particles of the present invention are in the form of a powder. In some embodiments, the particles of the present invention may be microglassified particles, and / or the hyaluronidase may be in the form of a microglassified hyaluronidase that is a particle and / or is contained in a particle. As used herein, "microglassification" refers to a process of removing water (e.g., dehydrating) from a component (e.g., hyaluronidase or a therapeutic agent) present in an aqueous composition (e.g., dissolved or suspended in the aqueous composition), the removal being carried out by contacting the aqueous composition with an organic phase (e.g., a non-aqueous organic phase) to provide a solid containing the component, wherein the solidified component may be referred to herein as a "microglassified" component. The microglassification process may be carried out in any manner that allows for contacting the organic phase with the aqueous composition containing the component, thereby removing water from the component. For example, in some embodiments, the microglassification process may be carried out by using a homogenizer (e.g., an in-line homogenizer) and / or a microfluidic device to contact the organic phase with the aqueous composition containing the component, and / or by spraying droplets of the aqueous composition containing the component into the organic phase, or vice versa, thereby contacting the organic phase with the aqueous composition. In a micro-vitrification process, the organic phase is a liquid organic phase (e.g., a liquid dehydrated composition) and the aqueous composition is a liquid. Thus, a micro-vitrification process involves a liquid-liquid mixture and / or system.The micro-vitrification process may involve contacting at least two different liquids. In some embodiments, the micro-vitrification process does not include a spray-drying step or spray-drying method, and / or does not involve spraying droplets of an aqueous composition containing the component into an organic phase or vice versa. In some embodiments, the micro-vitrification process without a spray-drying step or spray-drying method does not involve spraying droplets of an aqueous composition containing the component into a gas (e.g., a heated gas phase), and / or the micro-vitrification process does not involve a liquid-gas mixture and / or system. The micro-vitrified component is not a precipitate. In some embodiments, the particles of the present invention are not prepared by a method using a phase separation agent. As used herein, the term "phase separating agent" refers to an agent that precipitates a biological product from solution or that causes a liquid-liquid phase separation in which one liquid phase contains the majority of the biological product. Exemplary phase separating agents include, but are not limited to, salts (e.g., those that can be used for "salting out proteins") and polyethylene glycol (PEG). Although phase separation is a nucleation and growth process that can occur during the microvitrification process (e.g., liquid-liquid and / or liquid-solid), the microvitrified component is not formed by phase separation. Instead, microvitrification is a continuous phase transition that does not require nucleation to form the solidified component. The microvitrified component (e.g., microvitrified hyaluronidase) may redissolve in the original composition (e.g., aqueous solution) in which it was present and / or in an aqueous composition (e.g., aqueous buffer).

[0040] In some embodiments, a microvitrified component (e.g., microvitrified hyaluronidase) may be more stable (e.g., extended shelf life, expanded range of acceptable storage temperatures, and / or reduced degradation, optionally reduced degradation after repeated freeze / thaw cycles) than a solution of the component (e.g., a hyaluronidase solution where the hyaluronidase solution is not microvitrified). In some embodiments, microvitrification of a component (e.g., hyaluronidase) optionally improves the stability of the component compared to the stability of the same component in solution that is not microvitrified. In some embodiments, the hyaluronidase-containing particles of the invention have improved stability compared to hyaluronidase in solution when the hyaluronidase in solution is not particulate and not microvitrified, where the hyaluronidase in solution is not particulate and not microvitrified.

[0041] Particles comprising hyaluronidase can be in any form, such as, for example, microparticles, nanoparticles, microspheres, or nanospheres. The particles of the present invention can be amorphous and / or crystalline. In some embodiments, the particles of the present invention comprise amorphous particles. In some embodiments, the particles of the present invention comprise crystalline particles, for example, when a small molecule (e.g., a salt) that can be crystallized is present. The particles of the present invention can be uniform in size or polydisperse. In some embodiments, at least a portion of the particles of the present invention have a size that is within about ±5%, about ±10%, about ±15%, about ±20%, about ±25%, about ±50%, about ±75%, about ±100%, about ±150%, about ±200%, or greater of the average particle size. In some embodiments, the compositions of the present invention comprise discrete particles. The particles of the present invention have a mass of about 0.5 g / cm. 3 , about 0.6g / cm 3 , about 0.7g / cm 3 , about 0.8g / cm 3 , about 0.9g / cm 3 or about 1 g / cm3 From this, it is approximately 1.1 g / cm 3 , about 1.2g / cm 3 , about 1.3g / cm 3 , approximately 1.4 g / cm 3 , about 1.5g / cm 3 , about 1.6g / cm 3 , about 1.7g / cm 3 , about 1.8g / cm 3 , about 1.9g / cm 3 or about 2 g / cm 3 In some embodiments, the particles of the present invention may have a density of up to about 0.5 g / cm 3 , about 0.6g / cm 3 , about 0.7g / cm 3 , about 0.8g / cm 3 , about 0.9g / cm 3 , about 1g / cm 3 , about 1.1g / cm 3 , about 1.2g / cm 3 , about 1.3g / cm 3 , approximately 1.4 g / cm 3 , about 1.5g / cm 3 , about 1.6g / cm 3 , about 1.7g / cm 3 , about 1.8g / cm 3 , about 1.9g / cm 3 , or about 2 g / cm 3 In some embodiments, the particles of the present invention have a density of about 1.1 g / cm 3 ~Approx. 1.5g / cm 3 The density can be measured and / or determined using methods known to those skilled in the art, for example, using a gas pycnometer and / or by sedimentation experiments.

[0042] As used herein, "hyaluronidase" refers to an enzyme or a portion thereof (e.g., a domain thereof) that cleaves glycosidic bonds in glycosaminoglycans, such as, but not limited to, hyaluronic acid. As used herein, "hyaluronidase" refers to all forms of hyaluronidase from any organism (e.g., bacteria and / or mammals, such as humans and / or cows), including naturally occurring (e.g., wild-type hyaluronidase) and recombinant hyaluronidase. In some embodiments, the hyaluronidase present in the particles of the present invention cleaves at least hyaluronic acid, such as human hyaluronic acid, that may optionally be present in the skin and / or tissue of a subject.

For example, in some embodiments, the hyaluronidase may be ovine testicular hyaluronidase V (e.g., Millipore Sigma Catalog Number: H6254), optionally having a specific activity of 1,500 units or more per mg of solid. The hyaluronidase present in the particles of the invention may be synthetically obtained (e.g., synthesized in a laboratory) and / or may be naturally obtained and / or derived (e.g., from living or formerly living organisms). In some embodiments, the hyaluronidase may be the same as a hyaluronidase found in nature (i.e., a native hyaluronidase) or may be modified from a hyaluronidase found in nature (e.g., a modified hyaluronidase and / or a recombinant hyaluronidase).For example, the hyaluronidases of the invention may be modified to have a different structure, sequence, charge, chemical modification, and / or length than a naturally occurring hyaluronidase, and / or the hyaluronidase may be a portion of a naturally occurring hyaluronidase (e.g., the active domain of a naturally occurring hyaluronidase).

[0044] The particles of the present invention, and / or the hyaluronidase and / or therapeutic agent present in the particles, may dissolve in the aqueous composition upon and / or after contact with the aqueous composition. In some embodiments, contacting the particles of the present invention with the aqueous composition may be performed ex vivo and / or in vitro. In some embodiments, contacting the particles of the present invention with the aqueous composition may be performed in vivo, for example, during and / or after administration to a subject (e.g., subcutaneous administration) by contacting the particles with bodily fluids. All or a portion of the particles may dissolve in the aqueous composition, and / or all or a portion of the hyaluronidase and / or other components (e.g., therapeutic agents) present in the particles may dissolve in the aqueous composition.

[0045] The particles of the present invention may maintain and / or preserve one or more properties and / or functions compared to the same one or more properties and / or functions of the hyaluronidase and / or therapeutic agent prior to formation of the particles, and / or compared to a control hyaluronidase (e.g., free hyaluronidase) and / or control therapeutic agent not provided in particle form. In some embodiments, the particles of the present invention may enhance the stability of the hyaluronidase and / or therapeutic agent present in the particles compared to the stability of the hyaluronidase and / or therapeutic agent prior to formation of the particles. The control hyaluronidase may be and / or correspond to the same hyaluronidase used in the particles of the present invention, and the control therapeutic agent may be and / or correspond to the same therapeutic agent used in the particles of the present invention. In some embodiments, the control hyaluronidase is a commercially available hyaluronidase that is not provided in the form of a particle of the present invention, and the control hyaluronidase may be the same type as the hyaluronidase used in the particles of the present invention.

[0046] In some embodiments, after dissolving all or a portion of the particles of the invention and / or their components (e.g., hyaluronidase and / or therapeutic agent) in an aqueous composition, the activity of the component (e.g., hyaluronidase and / or therapeutic agent) is within about ±5%, about 10%, about 15%, about 20%, about 25%, about 30%, about 35%, about 40%, about 45%, or about 50% of the activity of the control component and / or the activity of the component before formation into a particle of the invention. The activity of the component (e.g., hyaluronidase and / or therapeutic agent) can be measured in the aqueous composition in which the particles are dissolved. The activity of the component (e.g., the enzymatic activity of hyaluronidase) can be measured by methods known to those skilled in the art. For example, hyaluronidase activity can be measured using the USP XXII Hyaluronidase Assay, EC 3.2.1.35, HAse and / or USP 29-NF24, page 1057. In some embodiments, hyaluronidase activity and / or changes in hyaluronidase activity can be determined and / or measured by measuring the viscosity of a composition comprising hyaluronidase and / or comparing the viscosity of a composition comprising hyaluronidase after contact with hyaluronic acid for a period of time. For example, in some embodiments, the viscosity of a composition comprising hyaluronidase can be measured and compared to a standard curve prepared using the viscosity of a composition comprising a specific amount of hyaluronidase after two or more different periods of time after contact with hyaluronic acid. In some embodiments, the control component is a control hyaluronidase and / or a control therapeutic agent. In some embodiments, hyaluronidase activity can be measured using a turbidimetric assay, such as that described in Dorfman, A. (1955) Methods in Enzymology, Volume I, 166-173 (1 unit corresponds to 1 NF unit as determined by the method described in USP XXII-NF XVII combined edition, p. 644 (1990)).For example, in some embodiments, the turbidity (e.g., optical density) of a composition comprising hyaluronidase can be measured as the percent transmittance of 600 nm light passing through 1 cm of a hyaluronic acid composition (e.g., a composition (e.g., a solution) comprising about 0.1 mg / ml, about 0.2 mg / ml, about 0.3 mg / ml, about 0.4 mg / ml, or about 0.5 mg / ml of hyaluronic acid present (e.g., dissolved in phosphate buffered saline)). In some embodiments, a reaction mixture containing or consisting of 160 mM sodium phosphate, 39 mM sodium chloride, 0.005% (w / v) bovine serum albumin, 0.015% (w / v) hyaluronic acid, and 1.5-5 units of hyaluronidase is incubated at 37°C for 45 minutes, and then 0.5 mL of the reaction mixture is added to 2.5 mL of an acidic albumin solution (0.1% (w / v) bovine serum albumin in 1:1 HCl:HO (pH 3.75)) and incubated at room temperature for 10 minutes. The percent transmittance at 600 nm is measured and compared to a standard curve. In some embodiments, one unit of hyaluronidase activity corresponds to a change in A600 of 0.330 per minute in a 2.0 mL reaction mixture (e.g., a reaction mixture comprising or consisting of 160 mM sodium phosphate, 39 mM sodium chloride, 0.005% (w / v) bovine serum albumin, 0.015% (w / v) hyaluronic acid, and 1.5-5 units of hyaluronidase) at pH 5.35 and 37° C. In some embodiments, the activity of the hyaluronidase and / or therapeutic agent after dissolution is compared to the activity of the hyaluronidase and / or therapeutic agent prior to particle formation of the invention. In some embodiments, after the particles of the present invention are dissolved in an aqueous composition, the enzymatic activity of the hyaluronidase present in the particles is within about ±5%, about ±10%, about ±15%, about ±20%, about ±25%, about ±30%, about ±35%, about ±40%, about ±45%, or about ±50% of the enzymatic activity of a control hyaluronidase (e.g., free hyaluronidase).For example, a hyaluronidase having a specific activity of 1,500 units per solid (wherein the solid is a form of hyaluronidase prior to particle formation, e.g., a lyophilized powder) may be included in and / or used to form a particle of the invention (e.g., the particle comprises 1,500 units of hyaluronidase activity per mg of solid, where the solid is a lyophilized powder of hyaluronidase prior to particle formation), and when the hyaluronidase-containing particle is dissolved (e.g., in whole or in part) in an aqueous composition, the dissolved hyaluronidase may have a specific activity of at least about 750 units per mg of solid. "Free hyaluronidase" refers to hyaluronidase that is not included in a particle of the invention.

[0047] In some embodiments, after storing the particles of the invention and then dissolving the particles (e.g., in whole or in part) in an aqueous composition, the activity of a component (e.g., hyaluronidase and / or therapeutic agent) within the particle can be within about ±5%, within about 10%, within about 15%, within about 20%, within about 25%, within about 30%, within about 35%, within about 40%, within about 45%, or within about 50% of the activity of a control component (e.g., a control hyaluronidase and / or a control therapeutic agent, respectively) and / or of the activity of the component prior to formation of the particle. In some embodiments, after storing particles of the invention and then dissolving the particles (e.g., all or part) in an aqueous composition, the enzymatic activity of the hyaluronidase present in the particles can be within about ±5%, within about 10%, within about 15%, within about 20%, within about 25%, within about 30%, within about 35%, within about 40%, within about 45%, or within about 50% of the enzymatic activity of a control hyaluronidase and / or of the hyaluronidase prior to formation of the particles.

[0087] In some embodiments, contacting a dehydrated composition (e.g., an organic solvent) with a composition comprising hyaluronidase and / or forming a mixture comprising the dehydrated composition and a composition comprising hyaluronidase can form a suspension. In some embodiments, the suspension comprises hyaluronidase in the form of a solid suspended in a liquid (e.g., a non-aqueous organic layer). Contacting the dehydrated composition with the composition comprising hyaluronidase to provide a mixture and forming an at least partially dehydrated component in the mixture can be performed substantially simultaneously. As used herein, with respect to at least partially dehydrating a component, "substantially simultaneously" refers to at least partially dehydrating the component immediately after contact with the dehydrated composition or within less than about 1 minute of initial contact with the dehydrated composition. In some embodiments, forming at least partially dehydrated components in the mixture is achieved within about 100 minutes (e.g., within about 90 minutes, within about 60 minutes, within about 30 minutes, within about 15 minutes, within about 10 minutes, within about 5 minutes, or within about 1 minute) after initial contact of the dehydrated composition with a composition comprising hyaluronidase.

[0089] According to some embodiments, contacting two different compositions (e.g., a dehydrated composition and a composition comprising hyaluronidase, or a composition comprising a solvent and at least partially dehydrated components) includes mixing them together. Mixing can be accomplished by any method known to those skilled in the art, such as vortexing, stirring, static mixing, homogenizing, extruding, pumping, injecting (e.g., microinjecting), adding one composition to the other, spraying one composition into the other, and / or spraying both compositions together to form a mixture. Mixing can form an emulsion. In some embodiments, air can be incorporated into the mixture. One composition can be added to the other using slow addition, fast addition, or total addition, and mixing can be achieved at low and / or high shear (e.g., about 1-10,000,000 / sec). When two different compositions include an aqueous composition and a hydrophobic composition (e.g., a composition containing an organic solvent), the aqueous composition may be added to the hydrophobic composition, or vice versa. In some embodiments, the two different compositions are contacted prior to mixing and / or in a mixer. Exemplary mixers include, but are not limited to, high-pressure homogenizers, rotor-stator homogenizers, impellers, pipeline mixers (turbulent and laminar), static mixers, in-line mixers, and / or microfluidic devices (e.g., microfluidic devices equipped with a cross junction). In some embodiments, the mixer is in-line, such as an in-line homogenizer.In some embodiments, the mixer is a device (e.g., a microfluidic device), and two different compositions may be added or injected into the device, thereby mixing the two different compositions with each other and forming the mixture. Forming the at least partially dehydrated component can include mixing (e.g., homogenizing) two different compositions and / or mixtures.

[0090] In some embodiments, two different compositions forming a mixture and / or a composition comprising at least partially dehydrated components can be mixed in a ratio that is the volume ratio of the two different compositions, for example, in a batch process. For example, for a first composition and a second composition that are contacted to form a mixture in a batch process, the volume ratio can be the ratio of the volume of the first composition to be mixed to the volume of the second composition to be mixed. In some embodiments, two different compositions forming a mixture and / or a composition comprising at least partially dehydrated components can be mixed in a ratio based on the feed rates of the two different compositions, for example, in an in-line process. For example, for a first composition and a second composition that are contacted to form a mixture in an in-line process, the ratio can be the ratio of the feed rate (e.g., flow rate) of the first composition during the contacting step to the feed rate (e.g., flow rate) of the second composition during the contacting step.

The feed rates for each component may be the same or different.

[0092] In some embodiments, two different compositions may be contacted and / or combined in a given volumetric ratio to form a mixture and / or a composition comprising at least partially dehydrated components. The two different compositions may include an aqueous composition (e.g., a composition comprising hyaluronidase and / or a composition comprising water) that provides an aqueous phase, and a solvent-containing composition (e.g., a hydrophobic composition) that provides a solvent phase. In some embodiments, the two different compositions are at about 0.1:100, about 0.2:100, about 0.3:100, about 0.4:100, about 0.5:100, about 0.6:100, about 0.7:100, about 0.8:100, about 0.9:100, about 1:100, about 1.5:100, about 2:100, about 2.5:100, about 3:100, about 3.5:100, about 4:100, about 4.5:100, about 5:100, about 5.5:100, about 6:100, about 6.5:100, about 7:100, about The components may be contacted and / or combined in a feed volume ratio of about 7.5:100, about 8:100, about 8.5:100, about 9:100, about 9.5:100, about 10:100, about 11:100, about 12:100, about 13:100, about 14:100, about 15:100, about 16:100, about 17:100, about 18:100, about 19:100, about 20:100, about 21:100, about 22:100, about 23:100, about 24:100, or about 25:100 (aqueous composition:solvent containing composition). In some embodiments, the two different compositions that form the mixture and / or composition comprising at least partially dehydrated components may be contacted and / or combined in a feed volume ratio ranging from about 0.1:100, about 0.3:100, about 0.5:100, about 0.7:100, or about 1:100, to about 2:100, about 4:100, about 6:100, about 8:100, about 10:100, about 12:100, about 14:100, about 16:100, about 18:100, about 20:100, about 22:100, or about 25:100.

[0093] The at least partially dehydrated components and / or particles of the present invention can be separated from the mixture and / or liquid phase using methods known to those skilled in the art. For example, the at least partially dehydrated components and / or particles of the present invention can be separated from the liquid phase by filtration (e.g., pressure filtration, tangential flow filtration, rotary filtration, centrifugal filtration, disc stack filtration, etc.), cyclone separation, sedimentation (e.g., acoustic resonant field induced precipitation), evaporation, centrifugation, fluidized bed drying, evaporative drying, thermal drying, freeze drying, atmospheric freeze drying, spray drying, spray freeze drying, microwave / infrared drying, and / or sieving. In some embodiments, the at least partially dehydrated components and / or particles of the present invention can be separated from the liquid phase by washing and / or solvent exchange methods, precipitation and / or filtration processes, and further dried (e.g., to remove water and / or solvent) by air, vacuum, and / or freeze-drying processes, and / or any combination thereof. In some embodiments, the at least partially dehydrated components and / or particles of the present invention can be separated from the liquid phase by washing and / or solvent exchange methods, precipitation and / or filtration processes, and / or further dried (e.g., to remove water and / or solvent) using air, vacuum, and / or freeze-drying processes, and / or any combination thereof.

[0094] In some embodiments, the method of the present invention includes washing the at least partially dehydrated components and / or particles of the present invention with a cleaning composition.

In some embodiments, the organic solvent in the cleaning composition is miscible with water. The organic solvent in the cleaning composition may be the same as or different from the organic solvent in the dehydrated composition. In some embodiments, the organic solvent present in the cleaning composition may be a Class II or Class III residual solvent as classified by the U.S. Food and Drug Administration.

[0095] In some embodiments, the organic solvent present in the cleaning composition may be more volatile than the organic solvent in the dehydration composition.

In some embodiments, the particles comprising the hyaluronidase dissolve in the liquid. In some embodiments, the liquid is an aqueous liquid (e.g., a body fluid and / or an aqueous buffer). The therapeutic agent may be present in the particles comprising the hyaluronidase, or may be separate from the particles comprising the hyaluronidase. In some embodiments, the therapeutic agent may be in particles different from the particles comprising the hyaluronidase, and the particles comprising the therapeutic agent may have a water content of less than about 15% by weight of the particles and / or a water activity of less than about 0.9, and may be solid particles. In some embodiments, the therapeutic agent may be separate from the particles comprising the hyaluronidase, and may be present in the composition in which the particles are present (e.g., dissolved and / or suspended in the composition). In some embodiments, the particles comprising hyaluronidase are present in a solvent different from the liquid.

[0103] In some embodiments, a method for increasing dissolution of a therapeutic agent in a liquid (e.g., in vitro and / or in vivo) can include separately combining particles comprising a therapeutic agent and hyaluronidase with the liquid. For example, the therapeutic agent and particles comprising hyaluronidase can be combined (e.g., added) sequentially with the liquid. In some embodiments, the combining includes simultaneously combining particles comprising hyaluronidase with the therapeutic agent in the liquid, optionally wherein the hyaluronidase and the therapeutic agent are present in the same particle or in different particles. Prior to and / or when combining the liquid with the particles comprising hyaluronidase, the composition comprising the liquid and / or particles can be free of hyaluronidase in solution (e.g., hyaluronidase dissolved in water) and / or free hyaluronidase. When the liquid and the particles containing the hyaluronidase are combined, the hyaluronidase and / or particles can dissolve in the liquid.

[0104] The methods of the invention may increase the solubility of a therapeutic agent in a liquid by at least about 5%, at least about 10%, at least about 20%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, or more over a period of time (e.g., from about 1 minute to about 2 hours) compared to dissolution of the therapeutic agent in the same liquid over the same predetermined period of time and under the same conditions (e.g., temperature and / or pressure) in the absence of the particles of the invention. In some embodiments, after combining the hyaluronidase-containing particles of the invention, the therapeutic agent, and a liquid, at least about 90%, at least about 95%, at least about 99%, or at least about 100% of the therapeutic agent is dissolved within about 10, 20, 30, or 40 minutes to about 50, 60, 70, 80, 90, 100, 110, or 120 minutes. In some embodiments, after initially combining the hyaluronidase-containing particles of the invention, the therapeutic agent, and a liquid, at least about 90%, at least about 95%, at least about 99%, or at least about 100% of the therapeutic agent is dissolved within about 10 minutes, about 20 minutes, about 30 minutes, or about 40 minutes, to about 50 minutes, or about 60 minutes.

In some embodiments, the methods of the invention may provide a subject with an increased total administered volume (e.g., at least about 5%; e.g., at least about 5%, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 40%, at least about 50%, at least about 60%, at least about 70%, at least about 80%, at least about 90%, at least about 100%, or more) compared to a method in which hyaluronidase is not administered.

[0124] The invention will now be illustrated in the following non-limiting examples.

[0125] Example

[0126] Example 1

[0127] Using a small-scale microvitrification method, particles containing hyaluronidase type 5 (SIGMA H6254-500MG lot SLCK4168) and sucrose (SIGMA 1.00892.1003 lot K52895792 03) were prepared in 17 mM Trizma buffer (SIGMA T1503-500G lot 068K5451) with or without bovine gamma globulin (RMBIO BGG-BBZ-01K lot 20150424IG). Three stock solutions were used: The first stock contained no hyaluronidase but 21 mg / g sucrose and 77 mg / g bovine gamma globulin. The second stock contained 21 mg / g sucrose, 71 mg / g bovine gamma globulin, and 10 mg / g hyaluronidase. The third stock contained 20 mg / g sucrose, no bovine gamma globulin, and 80 mg / g hyaluronidase. Particles were prepared by mixing 10–12 microliters of hyaluronidase stock with 1 milliliter of dry n-octanol (f value = 0.3). Particles were formed by vortexing with a homogenizer (IKA T-10) at setting 6 for 30 seconds. Once formed, a small sample of the suspension was taken for particle analysis. The suspension was centrifuged at 14,000 rcf for 10 minutes, and the octanol was carefully removed with a pipette. The particles were washed or decanted three times by adding n-pentanol, mixing, centrifuging (same settings as above), and then carefully removing the supernatant. The particles were dried under vacuum overnight and then sealed and stored at 5°C. The particles were spherical in shape and tested to measure enzyme activity.

[0128] Example 2

[0129] Dry, dense particles containing hyaluronidase, sucrose, and bovine gamma globulin (BGG) were produced using a microvitrification process. Three batches were produced. The resulting particles contained approximately 2% hyaluronidase by weight.

[0130] For the first batch, a protein stock solution was prepared at a total solids concentration of approximately 100 mg / ml. Octanol and aqueous stock were fed into an inline homogenizer (IKA T-25) equipped with a custom feed at a total flow rate of 176 ml / min (2.228 ml / min of which was aqueous). Approximately 10 ml of aqueous stock solution was processed. The resulting suspension was simultaneously fed into a 0.4 micron filter to recover the particles. The particles were then washed on the filter with pentanol and dried under nitrogen. The powder contained 1.1 wt% residual moisture, 0.1 wt% residual pentanol, and 0.5 wt% residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 11,321 particles were imaged for particle size analysis. The average particle size was 2.5 microns, and the largest particle measured was 8.5 microns.

[0131] For the second batch, a protein stock solution was prepared at a total solids concentration of approximately 102 mg / ml. Octanol and aqueous stock were fed into an in-line homogenizer (IKA T-25) equipped with a custom feed at rates of 156 ml / min and 1.963 ml / min, respectively. Approximately 99 ml of the aqueous stock solution was processed. The resulting suspension was then fed into a 0.4 micron filter to recover the particles. Filtration was performed at 10 atmospheres of pressure applied by compressed nitrogen. The particles were then washed on the filter with pentanol and dried under nitrogen. The powder contained 0.9 wt% residual moisture, 0.1 wt% residual pentanol, and 0.7 wt% residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 13,135 particles were imaged for particle size analysis. The average particle size was 2.4 microns, and the largest particle measured was 9.9 microns.

[0132] For the third batch, a protein stock solution was prepared with a total solids concentration of approximately 103 mg / ml. Octanol and aqueous stock were fed into an in-line homogenizer (IKA T-25) equipped with a custom feed at rates of 155 ml / min and 1.946 ml / min, respectively. Approximately 110 ml of aqueous stock solution was processed. The resulting suspension was then fed into a 0.4 micron filter to recover the particles. Filtering was performed at 10 atmospheres of pressure applied by compressed nitrogen. The particles were then washed on the filter with pentanol and dried under nitrogen. The powder contained 1.5 wt% residual moisture, 0.1 wt% residual pentanol, and 0.7 wt% residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 12,816 particles were imaged for particle size analysis. The average particle size was 2.6 microns, and the largest particle measured was 10.1 microns.

[0133] Example 3

[0134] In vitro release studies were performed and compared by using suspensions of microvitrified protein particles in either phosphate-buffered saline (PBS) containing 0.25 mg / mL hyaluronidase (PBS-Hyal medium) or PBS containing 0.5% hyaluronic acid and 0.25 mg / mL hyaluronidase (PBS-HA-Hyal medium). A release medium containing PBS and 0.25 mg / mL hyaluronidase was also included as a control. Particle suspensions contained bovine gamma globulin (BGG) and sucrose and were prepared in benzyl benzoate at a total solids concentration of 500 mg / mL. Approximately 10 μL of this suspension was added to 5 mL tubes containing either PBS-Hyal or PBS-HA-Hyal release medium.

[0135] The release medium containing the particle suspension was sampled over time, and the absorbance at 280 nm of the sampled release medium was measured to determine the amount of BGG released from the suspension over time after contact with the release medium (e.g., the concentration of BGG released from the particles and / or suspension and / or the concentration of BGG dissolved in the release medium after contact with the release medium). As can be seen from Figure 3, the sample containing the PBS-HA-containing release medium showed a slow release of BGG from the suspension over time, while the sample containing the PBS-HA-Hyal release medium, as seen in Figure 1, showed a rapid release of BGG from the suspension over time. The results of this experiment demonstrated the feasibility of using hyaluronidase in the aqueous phase to increase the dissolution rate of solidified proteins from non-aqueous suspensions, such as in the subcutaneous space.

[0136] Example 4

[0137] For three individual samples, suspensions of protein particles were tested for in vitro release in solutions of PBS (PBS medium-1, PBS medium-2, or PBS medium-3) or 0.5% hyaluronic acid (HA) in PBS (PBS-HA medium-1, PBS-HA medium-2, or PBS-HA medium-3) and compared. The in vitro release of suspensions of protein particles in PBS or HA was also compared to the in vitro release of suspensions of particles containing the same protein and hyaluronidase in PBS or HA.

[0138] A suspension of microvitrified particles containing bovine gamma globulin (BGG) and sucrose was prepared in benzyl benzoate at a total solids concentration of 500 mg / mL. Approximately 10 μL of this suspension was added to a 5 mL tube with PBS or HA as the release medium. The release medium containing the BGG particle suspension was sampled over time, and the absorbance of the sampled release medium at 280 nm was measured to determine the protein concentration in the release medium over time. Triplicate samples were prepared for each release medium used.

[0139] Figure 2 shows the measured absorbance over time for each of the three PBS medium samples, and Figure 3 shows the measured absorbance over time for each of the three PBS-HA medium samples. In Figures 2 and 3, the maximum measured absorbance indicates the time point for complete release of protein (BGG) from the suspension. As shown in Figure 2, the suspension added to PBS medium showed rapid release of protein over time, with complete release of protein completed within one hour. The suspension added to 0.5% hyaluronic acid (HA) release medium showed slower release, with complete release of protein occurring over several days, as shown in Figure 3.

[0140] A suspension of microvitrified particles containing hyaluronidase and BGG was prepared from a solution containing hyaluronidase at 2% by weight of the dissolved solids and BGG at approximately 98% by weight of the dissolved solids. The particles were prepared in the suspension in benzyl benzoate at a concentration of approximately 500 mg / mL of total solids. The same experiment as above was repeated, except that approximately 10 μL of the suspension containing particles containing BGG and hyaluronidase was added to a 5 mL tube with PBS or HA as the release medium. Assuming that hyaluronidase was completely released from the particles, there would be 0.025 mg of hyaluronidase per mL of the release medium, which is 10-fold less than the amount of hyaluronidase in Example 3. The release medium was sampled over time in the same manner as above, and the absorbance of the sampled release medium at 280 nm was measured to determine the protein concentration in the release medium over time. Three samples were prepared for each release medium used.

[0141] Figure 4 shows the measured absorbance over time for each of the PBS samples (PBS medium-1, PBS medium-2, or PBS medium-3) containing particles comprising BGG and hyaluronidase, and Figure 5 shows the measured absorbance over time for each of the three PBS-HA medium samples (PBS-HA medium-1, PBS-HA medium-2, or PBS-HA medium-3) containing particles comprising BGG and hyaluronidase. In Figures 4 and 5, the maximum measured absorbance indicates the time for complete release of the protein from the suspension. As shown in Figures 4 and 5, protein release from the suspension was complete within one hour for both the PBS and PBS-HA release media. These results indicate that the hyaluronidase contained within the solid protein particles efficiently degraded hyaluronic acid in the HA release media, allowing the protein to dissolve more quickly from the suspension into the aqueous layer of the release media. In addition, the amount of hyaluronidase in the particles prepared in Example 4 was approximately 25-fold lower than the amount of hyaluronidase added to the vehicle in Example 3, indicating that less hyaluronidase in particle form is required to increase protein release from the suspension compared to free hyaluronidase in solution.

[0142] Example 5

[0143] Protein release from suspensions containing solid particles with different amounts of hyaluronidase is compared. Particles having different amounts of hyaluronidase in the particles (e.g., 0.1%, 0.5%, 1%, 3%, or 4% by weight of the particles) can be prepared and can be prepared as described in one or more of Examples 1-4.

[0144] Example 6

[0145] Protein release from suspensions containing hyaluronidase particles of the present invention is compared to that from individual, solid protein particles. Particles containing different amounts of hyaluronidase (e.g., hyaluronidase in amounts of 0.1%, 0.5%, 1%, 3%, or 4% by weight of the particles) are prepared and may be prepared as described in one or more of Examples 1-4. Hyaluronidase particles are provided in suspensions with particles that do not contain hyaluronidase, and different concentrations of hyaluronidase are prepared. For example, suspensions containing hyaluronidase particles present at 0.1%, 0.5%, 1%, 3%, or 4% by weight of the total solids content of the suspension and suspensions containing particles that do not contain hyaluronidase may be prepared.

[0146] Example 7

[0147] The enzymatic activity of the hyaluronidase-containing solid protein particles was measured over time (e.g., by comparing turbidity to a standard curve for hyaluronidase EC 3.2.1.35 (HAse) using the method in Dorfman, A. (1955) Methods in Enzymology, Volume I, pp. 166-173) and compared to the activity of hyaluronidase in a stock formulation. Hyaluronidase-containing particles were prepared in formulations as shown in Table 1.

[0148] [Table 1]

[0149] Powders of the particle formulation were subjected to a 3-month stability test at 2-8°C or 25°C. At predetermined time points (initial (t=0), 30 days, and 90 days), the powders were rehydrated (20 mM sodium phosphate, pH 7.0, 37°C, 77 mM sodium chloride, and 0.01% (w / v) bovine serum albumin), and enzyme activity was measured as described in Dorfman, A. (1955) Methods in Enzymology, Volume I, pp. 166-173. The results are shown in Figures 6 and 7.

[0150] Example 8

[0151] Using the Gottingen minipig model, injection site reactions and pharmacokinetics are compared for an injectable suspension in a non-aqueous vehicle with or without hyaluronidase particles of the present invention and an injectable suspension containing microvitrified particles containing a therapeutic agent, with or without hyaluronidase.

[0152] Formulations were prepared according to the table below (BB = benzyl benzoate; EO = ethyl oleate).

[0153] [Table 1A]

[0154] The animals used were male Göttingen minipigs aged 7 to 8 months. 2 ml of each formulation was injected intraperitoneally over approximately 10 seconds using a 27G needle (4 groups per animal, 4 animals per group, a total of 8 animals). Local changes at the injection site (warmth, redness, swelling, and bleb size) were scored immediately after injection, 1 hour, 2 hours, 3 hours, 4 hours, and 6 hours after injection, and once daily for 14 days after injection.

[0155] Example 9

[0156] Dry, dense particles containing hyaluronidase, sucrose, and bovine serum albumin (BSA) were produced using a microvitrification process and compared with BSA particles without hyaluronidase. Two batches were produced. The resulting enzyme-containing particles contained approximately 0.37% hyaluronidase by weight of the particle.

[0157] For the first batch, a stock solution of BSA and sucrose was prepared at a total solids concentration of approximately 85 mg / ml. Octanol and aqueous stock were fed into an in-line homogenizer (IKA T-25) to produce discrete, spherical solid particles. Approximately 33 ml of the aqueous stock solution was processed. The resulting suspension was washed with solvent, filtered, and dried under nitrogen. The powder contained 3.2 wt.% residual moisture, 0.3 wt.% residual wash solvent, and 5.2 wt.% residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 8,559 particles were imaged for particle size analysis. The average particle size was 2.7 microns, and the largest particle measured was 11.9 microns.

[0158] For the second batch, a stock solution of BSA, sucrose, and hyaluronidase was prepared at a total solids concentration of approximately 85 mg / ml. Octanol and the aqueous stock were fed into an in-line homogenizer (IKA T-25) to produce discrete, spherical solid particles. Approximately 33 ml of the aqueous stock solution was processed. The resulting suspension was washed with solvent, filtered, and dried under nitrogen. The powder contained 4.2% by weight residual moisture, 0.2% by weight residual washing solvent, and 5.3% by weight residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 12,583 particles were imaged for particle size analysis. The average particle size was 2.5 microns, and the largest particle measured was 10.7 microns.

[0159] The powder was subjected to stability testing for one month at 2-8°C, 25°C, and 40°C. At the designated time points, the powder was rehydrated and enzyme activity was measured as described in Dorfman, A. (1955) Methods in Enzymology, Volume I, 166-173 (Figure 8), and BSA aggregation was measured by SEC-HPLC (Figure 9).

[0160] Example 10

[0161] Dry, dense particles containing hyaluronidase, trehalose, and a monoclonal antibody (mAb) were fabricated using a microvitrification process and compared with mAb particles without hyaluronidase. Two batches were fabricated. The enzyme-containing particles contained approximately 0.3% hyaluronidase by weight of the particle.

[0162] For the first batch, a stock solution of mAb and trehalose was prepared at a total solids concentration of approximately 101 mg / ml. Octanol and aqueous stock were fed into an in-line homogenizer (IKA T-25) to produce discrete, spherical solid particles. Approximately 10 ml of the aqueous stock solution was processed. The resulting suspension was washed with solvent, filtered, and dried under nitrogen. The powder contained 1.8% by weight residual moisture, 0.1% by weight residual washing solvent, and 0.5% by weight residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 12,779 particles were imaged for particle size analysis. The average particle size was 2.6 microns, and the largest particle measured was 8.9 microns.

[0163] For the second batch, a stock solution of mAb, hyaluronidase, and trehalose was prepared at a total solids concentration of approximately 100 mg / ml. Octanol and aqueous stock were fed into an in-line homogenizer (IKA T-25) to produce discrete, spherical solid particles. Approximately 10 ml of the aqueous stock solution was processed. The resulting suspension was washed with solvent, filtered, and dried under nitrogen. The powder contained 0.6% by weight residual moisture, 0.1% by weight residual washing solvent, and 0.4% by weight residual octanol. A sample of the unfiltered suspension was retained for particle size analysis. 11,742 particles were imaged for particle size analysis. The average particle size was 2.7 microns, and the largest particle measured was 16.1 microns (Figure 10).

[0164] The powders were subjected to stability testing for 60 days at 2-8° C., 25° C., and 40° C. After 0, 15, and 30 days, the powders were rehydrated and the percent monomer of the mAb was measured via SEC-HPLC (FIGS. 11, 12, 13, 14, 15, and 16), and the enzyme activity was measured as described in Dorfman, A. (1955) Methods in Enzymology, Volume 1, 166-173 (FIG. 17).

[0165] Example 11

[0166] In contrast to Example 10, particles were produced using a microbatch microglassification process. In this process, approximately 12 μL of aqueous stock solution was processed for each sample. Particle formulations containing mAb, hyaluronidase, and various excipients (Table 2) were formed and stability tests were performed at 40°C. After 12 days, the powder was reconstituted, and enzyme activity was assayed as described in Dorfman, A. (1955) Methods in Enzymology, Volume I, pp. 166-173, and the aggregation state of the mAb was measured using SEC-HPLC (Table 3).

The powder is assayed for activity using one of the methods described above.
