DETAILED DESCRIPTION OF THE DISCLOSURE

While preferred embodiments of the present disclosure have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions will now occur to those skilled in the art without departing from the present disclosure. It should be understood that various alternatives to the embodiments of the present disclosure described herein may be employed. It is intended that the following claims define the scope of the present disclosure and that methods and structures within the scope of these claims and their equivalents be covered thereby.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of skill in the art to which the present disclosure described herein belong. All publications, patents, and patent applications mentioned in this specification are hereby incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference.
The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described. All documents, or portions of documents, cited in the application including, without limitation, patents, patent applications, articles, books, manuals, and treatises are hereby expressly incorporated by reference in their entirety for any purpose.
Pulmonary fungal infections are serious infections that usually occur in patients with compromised immune systems and lead to significant mortality and morbidity in such patients. The standard course of treatment requires the administration of antifungal agents intravenously or orally; however, such systemic delivery is associated with numerous side effects, ranging from phlebitis at the infusion site and chills to renal toxicity. The aerosolized delivery of antifungal agents is an attractive alternative for the prevention and treatment of pulmonary fungal lung infections because it allows for the concentrated delivery of the anti-fungal agent directly to the site of infection with minimal systemic exposure, thus limiting the potential side effects usually associated with intravenous delivery.
The antifungal agent caspofungin is an attractive candidate for aerosolized antifungal therapy. Caspofungin, a macrocyclic lipopeptide, is a member of a class of antifungal agents known as echinocandins, which inhibit the synthesis of glucan in the fungal cell wall through the noncompetitive inhibition of 1,343 glucan synthesis. Caspofungin has significant activity against fungal infections caused by the Candida species, Aspergillus species and Pneumocystis carinii pneumonia. Furthermore, caspofungin is relatively less toxic than other antifungal agents that are commonly employed for anti-fungal treatment, such as amphotericin B. Despite these advantages, there are no commercially available aerosol formulations of caspofungin for the prevention and/or treatment of antifungal infections.
The commercial formulation of caspofungin is a lyophilized, diacetate salt containing sucrose, mannitol, glacial acetic acid and sodium hydroxide and is reconstituted for intravenous use. Sold by Merck & Company, Inc under the trade name Cancidas®, caspofungin is the first member of the echinocandins to receive US Food and Drug Administration and has been approved for the treatment of invasive aspergillosis in patients who are refractory to or intolerant of other therapies; the empirical therapy for presumed fungal infections in febrile, neutropenic patients; the treatment of candidemia; intra-abdominal abscesses, peritonitis and pleural space infections caused by candida infections, and the treatment of esophageal candidiasis.
One challenge in administering caspofungin is that caspofungin is unstable and prone to degradation, especially at room temperature (−25° C.). As such, caspofungin is stored under low temperatures (e.g. 2-8° C.) and is used shortly after reconstitution. There have been various efforts at developing caspofungin formulations with improved stability. The development of the acetate salt of caspofungin, which led to the formulation of Cancidas®, was an improvement over earlier formulations that used the tartrate salt (U.S. Pat. No. 5,952,300). Another example include a formulation that eliminated the acetic acid and sodium hydroxide present in Cancidas® as pH modifiers, wherein the lyophilized and reconstituted formulations demonstrated improved stabilities at 25° C. when compared to the conventional formulations of caspofungin (U.S. Patent Publication 2009/0170753). In another example, a non-reducible sugar, such as trehalose, was used to replace the sucrose and mannitol present in the Cancidas® to provide formulations that have improved storage stability (US Patent Publication 2010/0137197).
Described herein are methods of treating and/or preventing fungal infections in the pulmonary system in a subject in need thereof comprising administering to the subject a composition caspofungin, or a polymorph, pharmaceutically acceptable salt, hydrate, or solvate thereof. In some embodiments, the composition is essentially free of mannitol. In some embodiments, the composition is essentially free of sugar alcohol. In some embodiments, the composition is essentially free of sugar alcohol or sugar. In some embodiments, the composition further comprises an anti-forming agent. The methods described herein allow for the localized and concentrated delivery the caspofungin, or a polymorph, pharmaceutically acceptable salt, hydrate, or solvate thereof directly to the site of infection, the pulmonary tissues, while minimizing the systemic exposure of caspofungin, or a polymorph, pharmaceutically acceptable salt, hydrate, or solvate thereof to other organs.

Echinocandin Tissue Distribution

There are three echinocandins approved for antifungal therapy: caspofungin, micafungin and anidulafungin. All of these compounds are active against a similar range of fungi and are structurally very similar as they are chemically close analogs. Despite their structural similarities it is recognized herein that their distribution and disposition in animals and humans are markedly different and not predictable. For instance, in rat studies, anidulafungin rapidly distributes into tissues to achieve peak concentrations within 30 min and maintains levels above MICs for common pathogens over 72 hours. Furthermore anidulafungin exposure is 9-12 fold higher in tissues susceptible to fungal infection, such as the liver, lung, spleen, kidney, than in plasma (Damle et al., Pharmacokinetics and Tissue Distribution of Anidulafungin in Rats, Antimicrob. Agents Chemo., 2008, 52, 7, p 2673-2676). In contrast, in rat studies, micafungin distributes moderately into the liver, kidney, and lungs, and the tissue concentrations decrease in parallel with micafungin in plasma. Micafungin exposures in the liver, kidney, and lung are 1.6, 3.4, and 2.9 fold higher than that for plasma (Niwa et al., Tissue Distribution after Intravenous Dosing of Micafungin, an Antifungal Drug, to Rats. Bio Pharm Bull, 2004, 27, 7, p 1154-1156). It is clear from these studies that tissue/plasma ratios and, thus, the overall tissue penetration for micafungin is considerably less than that observed with anidulafungin.
Caspofungin's tissue distribution has also been examined in non-human species using radiolabeled compound caspofungin (Hadju et al., Preliminary Animal Pharmacokinetics of the Parenteral Antifungal Agent MK-0991 (L-743,872), Antimicrob. Agents Chemo., 1997, 41, 11, p 2339-2344; Stone et. al, Disposition of Caspofungin: Role of Distribution in Determining Pharmacokinetics in Plasma, Antimicrob. Agents Chemo., 2004, 48, 3, p 815-823; and Sandhu et al., Disposition of Caspofungin, a Novel Antifungal Agent, in Mice, Rats, Rabbits, and Monkeys, Antimicrob. Agents Chemo., 2004, 48, 4, p 1272-1280). However, the use of radiolabeled material enables the detection of both parent compound and labeled metabolites, but not the ability to distinguish between them. As such, the reported quantitation of caspofungin may be all caspofungin, all metabolites or an unknown mix of the two with the final case being the most likely scenario. Caspofungin levels in plasma (but not other tissues) were also analyzed for parent compound by Sandhu in 2004. The most complete analysis of caspofungin tissue distribution was published by Stone in 2004 also using radiolabeled material. Comparing Stone's reported radioactive plasma distribution with Sandhu's analysis of the parent compound in plasma it is clear that the parent compound could be 17%, 24% or even 49% of the reported radiolabeled amount. From these studies, it is clear that the tissue distribution of caspofungin has not been determined and is not predictable from comparisons with other echinocandins.
Disclosed herein are tissue distribution studies of caspofungin via intravenous and inhalation administration. The lung retention and tissue distribution characteristics of caspofungin, let alone any approved echinocandin, upon inhaled delivery has not been reported.

Inhalation Devices

An “inhalation device,” as used herein, refers to any device that is capable of administering a drug formulation to the respiratory airways of a patient. Inhalation devices include conventional inhalation devices, such as jet nebulizers, ultrasonic wave nebulizers, high efficiency nebuilizers, heat vaporizers, soft mist inhalers, thermal aerosol inhaler, or electrohydrodynamic-based solution misting inhaler. Nebulizers deliver pharmaceuticals by forming an aerosol which includes droplet sizes that can easily be inhaled. The aerosol can be used by a patient within the bounds of an inhalation therapy, whereby the caspofungin reaches the patient's respiratory tract upon inhalation.
Conventional inhalation devices may be mechanical or electrical, and include, for example, jet nebulizers and ultrasonic nebulizers. Jet nebulizers generally utilize compressors to generate compressed air, which breaks the liquid medication into small breathable droplets, which form an aerosolized (atomized) mist. In some embodiments, when the patient breathes in, a valve at the top opens, which then allows air into the apparatus, thereby speeding up the mist generation; when the patient breathes out, the top valve closes, thereby slowing down the mist generation while simultaneously permitting the patient to breathe out through the opening of a mouthpiece flap. Some nebulizers may provide the aerosol in a continuous mode (e.g., the eFlow from PARI Pharma Starnberg), by a breath enhanced mode (e.g., the PARI LC Plus or Sprint from PARI Starnberg), by breath actuated mode dependent on the breathing pattern of the patient (e.g., the AeroEclipse from Trudell, Canada or the I-Neb from Philips Respironics), or according to given inhalation profile (e.g., the Akita from Activaero, Gmuenden, Germany).
Some conventional inhalation devices are disclosed in U.S. Pat. Nos. 6,513,727, 6,513,519, 6,176,237, 6,085,741, 6,000,394, 5,957,389, 5,740,966, 5,549,102, 5,461,695, 5,458,136, 5,312,046, 5,309,900, 5,280,784, and 4,496,086, each of which is hereby incorporated by reference in its entirety.

EXAMPLES

Example 1: Pharmacokinetic Studies with Caspofungin Formulations

Experimental Design: Caspofungin was administered to rats at a target dose of 2 mg/kg by nose only inhalation (by deposition) or intravenously (IV) to determine the plasma and tissue concentrations and pharmacokinetics.
Whole blood samples were collected from three animals per time-point at approximately 0.5, 1, 2, 4, 8, 12, 24 and 48 hours and 7 days after dose administration for plasma drug level determination. Rats were anesthetized with 70% CO2/30% air and blood was collected from the retro-orbital plexus and placed into tubes containing anticoagulant (EDTA). Blood samples were placed on ice immediately following collection and processed (i.e., centrifuged) to plasma. The samples were then stored frozen (at approximately −70° C.) until analyzed.
Tissue specimens (lung, liver and kidney) were collected from three animals per time point at 0.5, 2, 24 and 48 hours and 7 days after dose administration. All tissue specimens were stored frozen at approximately −70° C. until analyzed.
Plasma and tissue samples were analyzed for levels of caspofungin using high performance liquid chromatography-mass spectrometry-mass spectrometry (LC-MS-MS) according to methods established for the study.
Exposure of male rats to caspofungin via nose-only inhalation or via intravenous injection resulted in no test-article related mortality; no clinical signs of toxicity; no effects on body weight; and no gross necropsy findings attributable to exposure to the test article.
In Vivo Details: Thirty Sprague-Dawley derived rats [Crl:CD®(CD)Br] were obtained from Charles River Laboratories, Inc., Wilmington, Mass., for use in this study. The rats were 52 days of age (approximately 7.5 weeks) upon arrival. One day following receipt, body weights of the rats ranged from 171 g to 213 g. The animals were held in quarantine for 7 days prior to administration of the test article. Throughout the quarantine period, animals were observed at least once daily for mortality or evidence of a moribund state. Before being released from quarantine, the animals were given a detailed, hand-held physical examination to ensure their health and suitability as test subjects. The test animals were approximately 8.5 weeks old at the start of the first exposure to the test article.
During non-exposure periods of the study all animals were housed in Lab Products Inc., polycarbonate “shoe-box” cages (10.5″×19″×8″), with absorbent hardwood chip bedding. The animals were double housed for the quarantine period), in cages equipped with automatic water and food containers. Animals were double housed for the treatment period in cages equipped with automatic water and food containers. Following group assignment, racks and cages were cleaned and sanitized.
Animal room environmental conditions were recorded at least once daily throughout the quarantine and exposure periods. Temperatures ranged from 20° C. to 21° C. throughout the study, and relative humidity (% RH) values ranged from 46 to 56%. Fluorescent lighting in the animal room was provided on a cycle of 12 hours of light followed by 12 hours of darkness (light from approximately 6:00 a.m. to 6:00 p.m.).
To condition the animals to placement and restraint in the nose-only exposure system and reduce stress during the exposure phase, the animals were acclimated to the holding tubes by placing each rat in a nose-only holding tube for approximately 45 minutes one working day prior to exposure.
The study complied with all applicable sections of the Animal Welfare Act (AWA; Title 9, Code of Federal Regulations), the Public Health Service Policy on Humane Care and Use of Laboratory Animals (National Institutes of Health's Office of Laboratory Animal Welfare, 2002), and the Guide for the Care and Use of Laboratory Animals (National Research Council, 2011). To the extent possible, procedures used in this study were designed to avoid or minimize discomfort, stress, and pain to animals.
The animals were fed Harlan's Certified Global 18% Protein Rodent (2018C). Each certified lot of diet was analyzed for contaminants to ensure that none are present at concentrations that would be expected to interfere with the conduct or purpose of this study. Analytical data from the lots of diet to be used in the study are retained on file. Coarse-filtered City of Chicago water was provided ad libitum to all rats via automatic watering system. Supply water is analyzed periodically for bacterial contamination and chemical composition (e.g., electrolytes, metals, etc.).

Test Article Preparation:

Solution for inhalation: A 10 mg/mL dosing solution was prepared by dissolving 800 mg of caspofungin diacetate powder in 80 mL of 0.9% saline solution. The resulting solution was aseptically filtered and kept refrigerated between 2-8° C. until used.
Solution for IV administration: A 2 mg/mL dosing solution from commercially obtained Cancidas (containing 54.6 mg of caspofungin diacetate) was prepared by a) adding into 10.8 mL of 0.9% saline into the Cancidas vial and swirling gently until the powder dissolved. 10.0 mL of this solution was extracted and added a 25 mL volumetric flask which was diluted to the mark with 0.9% saline and mixed well. The resulting solution was aseptically filtered and kept refrigerated between 2-8° C. until used.
Test Article Dosing: The animals were randomized into two groups of 15 animals based on body weight. Each group was dosed as shown in Table 1 below.

TABLE 1

			Duration	Number of
Exposure Group	Target Dose	Route	(minutes)	Animals

I	2 mg/kg	Inhalation	123	15
II	2 mg/kg	IV	N/A	15

The dose targeted for deposition via inhalation was 2 mg/kg and was calculated based on this equation:
Deposited dose=(C×RMV×T×DF)/BW
where C is the average caspofungin concentration in the exposure atmosphere during the exposure period, RMV is the respiratory minute volume, T is the exposure time, DF is the deposition fraction (assumed to be 10% per FDA guidelines) and BW is the average animal body weight on exposure day.
The dose for IV administration was calculated based on the body weight of each animal
Delivered dose=W×2 mg/kg
where W is animal weight (kg).

Inhalation Exposure Methods:

Inhalation Exposure Laboratory: The inhalation exposure part of the study was conducted in an inhalation facility. The supply air to the laboratories was preconditioned and automatically controlled with a thermostat and humidistat. Each flow-past nose-only inhalation exposure chamber (Lab Products Inc., Seaford, Del.) is comprised of 52 ports. The chambers were encased in an acrylic enclosure to isolate the exposure chamber and protect laboratory personnel. The test atmosphere inlet and exhaust configurations provided a uniform and continuous stream of fresh test atmosphere to the animals undergoing exposure. After flowing out of the supply port, any excess test atmosphere, along with exhaled air, is drawn into the chamber exhaust manifold without entering other ports.
During the inhalation exposure, the animals were restrained in nose-only holding tubes (CH Technologies, USA, Westwood, NJ). Following confirmation of the correct animal number, each tube was placed in a pre-designated port of the inhalation exposure chamber. Chamber ports were rotated for each exposure; placement for each exposure is documented in the study records. Animal tube loading and unloading and tube insertion and removal from the chamber manifold processes were performed according to laboratory standard operating procedures that are designed to minimize stress to the rats. The rats were observed frequently while restrained to ensure that they remained in the tubes and were not in danger of injury. At the end of each exposure, when the chamber was purged of the test substance (less than one minute), the tubes with the animals were removed. The rats were removed from the tubes and returned to their home cages. The holding tubes were sanitized after each use.
Test Atmosphere Generation: Test atmosphere at the desired concentrations was generated by aerosolizing the test substance and mixing it with compressed filtered air to produce a continuous supply of test atmosphere. Test atmospheres were generated by aerosolizing the test formulation with a commercially available nebulizer using compressed air of breathable quality and which is filtered with a compressed air filter and a carbon adsorber.
Exhaust from the exposure chambers was moved through a high efficiency particulate air (HEPA) filter by a ring compressor and exhausted outside the building. Inlet and exhaust flows to and from the chamber were controlled and continuously monitored by rotometers.

Test Atmosphere Monitoring:

Gravimetric Analysis:
The test atmosphere concentration in the exposure chamber was determined gravimetrically each exposure by collecting test atmosphere samples on filters placed in closed-face filter holders in the breathing zone of the animals. The gravimetric sampling train consisted of a pre-weighed filter in series with a dry-gas meter connected to a constant flow vacuum pump. Samples were collected at a constant flow rate equal to the port flow of the delivery tube. The filter samples were weighed to determine the aerosol mass collected. The dry-gas meter measured the corresponding volume of chamber air sampled and the weight-to-volume ratio was determined to obtain the aerosol mass concentration.
Aerosol Particle Size Distribution:
Aerosol particle size distribution was determined once with a quartz crystal microbalance (QCM) cascade impactor (California Measurements Inc., Sierra Madre, Calif.) equipped with 10 stages to collect size-segregated samples. The mass median aerodynamic diameter (MMAD) and geometric standard deviation (GSD) were calculated from the mass accumulated on each collection stage of the QCM.
Temperature, Relative Humidity and Airflow Rate:
Inhalation exposure chamber temperature, relative humidity and airflow rate (liters per minute; LPM) were measured and recorded once during the exposure. The chamber temperature and relative humidity were monitored with a hand-held thermohygrometer (35612 series, Oakton Instruments, Vernon Hills, Ill.).

Intravenous Administration:

Animals in the IV dosing group received a single injection via the tail vein at a dosing volume of 1 mL/kg.

Toxicology Methods:

Moribundity/Mortality Observations and Physical Examinations/Clinical Observations: Prior to initiation of dosing (exposure), animals were observed at least once daily for mortality or evidence of moribundity. A detailed, hand-held physical examination was conducted on all animals once during the quarantine period (prior to randomization). During the treatment period, the animals were observed daily for mortality or evidence of moribundity; these checks were separated by a minimum of four hours. Daily cage-side clinical observations were conducted during exposure, and daily hand-held clinical observations were conducted before and after exposure. Observations included, but were not limited to the following: changes in the skin and fur, eyes, and mucous membranes; effects on the respiratory, circulatory, autonomic and central nervous systems; and effects on somatomotor activity and behavior pattern.
Body Weights and Body Weight Changes: Body weights were determined one day after animal receipt; at randomization; and prior to exposure on Study Day 1, 2, 3 and 7 (as applicable based on scheduled euthanization).
Plasma and Tissue Samples/Necropsy: Whole blood samples were collected from three animals per time-point at approximately 0.5, 1, 2, 4, 8, 12, 24 and 48 hours and 7 days after dose administration for plasma drug level determination. Rats were anesthetized with 70% CO2/30% air and blood was collected from the retro-orbital plexus and placed into tubes containing anticoagulant (EDTA). Blood samples were placed on ice immediately following collection and processed (i.e., centrifuged) to plasma. The samples were then stored frozen (at approximately −70° C.) until analyzed. All study animals surviving to scheduled necropsy were euthanized by an overdose of an intraperitoneal injection of sodium pentobarbital at 35-45 mg/kg. Tissue specimens (lung, liver and kidney) were collected from three animals per time point at 0.5, 2, 24 and 48 hours and 7 days after dose administration. All tissue specimens were stored frozen at approximately −70° C. until analyzed.

Bioanalytical Method and Analysis:

Calibration and Internal Standards: The reference standard, caspofungin acetate (lot number 02220902; Chunghwa Chemical Synthesis & Biotech, Taiwan), was stored at approximately −70° C.; and used without further purification for the preparation of calibration standards and quality control (QC) samples for the determination of caspofungin in plasma and tissue samples collected from this study. The internal standard (caspofungin acetate-d4; lot number 10-GJF-162-1) was stored at −20° C.
Sample Preparation: For the determination of caspofungin in plasma, a 100 μL aliquot from each sample (in a 2 mL centrifuge tube) was mixed with 0.3 mL of acetonitrile (ACN; Spectrum, New Brunswick, N.J.) containing 150 ng of internal standard. After shaking for five minutes, the sample was centrifuged at 4° C. for 10 minutes to remove precipitated proteins and supernatant was transferred to an autosampler tube, diluted with 0.5 mL of water, and vortex-mixed for instrumental analysis.
For the determination of caspofungin in tissue, samples (lung—entire organ; liver—1 gram; kidneys—one organ) were finely cut and extracted for analysis by adding 2.5 mL of ASTM Type I water and shaking for approximately 0.5 hour, after which 2.5 mL of acetonitrile (ACN; Spectrum, New Brunswick, N.J.) were added following by shaking for another 0.5 hour. Subsequently, 100 μL of the supernatant was transferred to a 2 mL centrifuge tube and processed for analysis using the same procedure as for plasma.
Freshly prepared caspofungin standard curves and quality control (QC) samples were analyzed along with the study samples. Instrument calibrators and QC samples were prepared by adding 10 μL of a stock caspofungin solution in ACN/water (v/v 50/50) to 100 μL of blank rat plasma (for both plasma and tissue samples). Calibrator concentrations for plasma specimen analysis were approximately 0.050, 0.10, 0.20, 0.50, 1.0, 2.5, 5.0 and 10 μg/mL; QC samples were prepared at approximately 0.12, 4.0 and 8.0 μg/mL. Calibrator concentrations for tissue specimen analysis were approximately 1, 2, 5, 10, 20, 50 and 100 ng/sample; QC samples were prepared at approximately 2.4, 40 and 80 ng/sample. Calibrators and QC samples were processed for analysis following the procedure described above.
Analytical Equipment and Conditions: Calibrator, QC and study samples were analyzed under LC-MS-MS instrument conditions as detailed in Table 2.
The retention time of caspofungin was approximately 2.3 minutes. Calibration curves were calculated from the linear regression (weighting factor of 1/x²) of the caspofungin peak area to internal standard peak area ratios versus caspofungin concentration. Concentration of caspofungin in the samples was determined using the peak area ratio and the regression parameters of the calibration curve. Tissue results in ng were converted to μg/g using the amount of tissue extracted and the final extract volume.

The half-life of caspofungin in the lung, as determined from the studies described herein, is 39 hours i.e. every 39 hours 50% of the remaining drug is eliminated from the lung. A projection of the amount of caspofungin remaining in the lung following a time period equivalent to one half-life is shown below in Table 8. The lung concentration columns show two starting concentrations; one is the concentration measured in the rat lung from the 2 mg/kg dose, the second is the projected concentration that would result from an inhaled dose of 7.2 mg/kg. To be effective the drug concentration should remain above the MIC and MEC. The average MIC and MEC for caspofungin versus Aspergillus fumigatus, the species most commonly associated with Aspergillosis is 0.25 μg/L.

The measurement of the particles produced during the inhalation experiment showed that they had a MMAD=1.15 μm with a GSD (geometric standard deviation) of 2.67.

Example 2: Comparative Tissue Distribution Studies of Caspofungin

A pharmacokinetic study was performed in rats to investigate the distribution of caspofungin parent compound to the organs most associated with Aspergillosis and compound safety (i.e. lungs, liver and kidney) when delivered either through an intravenous or inhaled route. A comparison with the radiolabeled data from Stone 2004 (Stone, et. al. Disposition of Caspofungin: Role of Distribution in Determining Pharmacokinetics in Plasma, Antimicrob. Agents Chemo., 2004, 48, 3, p 815-823) is shown in Table 9. It is clear that the amounts of caspofungin recovered from the IV dosed study are substantially different from the previously reported caspofungin concentrations. Not only are the distributions significantly different, but they are in no way predictable.

Example 3: Prophylactic Efficacy of Aerosol Caspofungin in Experimental Pulmonary Aspergillosis

The objective of the study is to determine the antifungal efficacy of the caspofungin formulations administered via inhalation therapy in the prophylaxis of invasive pulmonary aspergillosis in rats.
The experimental procedures are performed according to the procedures described in van de Cicogna et. al., Antimicrob. Agents Chemother. 1997, 41, 259-261 with further modifications. Caspofungin is used instead of amphotericin B.
The caspofungin formulation used herein include any one of the formulations as described herein, such as those from Example 1, or any one of the following formulations: Formulation 1: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N²-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B₀diacetate) (i.e. 50 mg or 70 mg), sucrose (i.e 34 mg or 54 mg), glacial acetic acid, sodium hydroxide; and Formulation 2: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N2-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B0 diacetate), glacial acetic acid, sodium hydroxide.
Male Sprague-Dawley rats (Charles River Breeding Laboratories, Wilmington, Mass.) are fed a low-protein diet (8% protein, Dyet, Bethelhem, Pa.) and are given a suitable amount of tetracycline (i.e. 250 mg dissolved in 750 mL of drinking water) to prevent bacterial infection. Furthermore, rats are treated with subcutaneous injections of cortisone acetate (150 mg/kg of body weight) three times a week under anesthesia with enflurane. These injections are either given for two weeks until the day of injection (trial 1) or throughout the duration of the experiment (trial arm 2).
Aspergillus fumigatus H11-20 is obtained from a steroid-treated rat dying from spontaneously acquired pulmonary aspergillosis. Other clinical strains of Aspergillus fumigatus are also suitable for these experiments. Suitable pores are obtained from subculturing the organism on Sabouraud dextrose for an appropriate time (i.e. 4 to 5 days) and are harvested with 0.02% Tween 80 and washed with sterile saline. The final suspension containing the desired amount of spores/mL, such as 10⁷spores/mL, is prepared and confirmed by counting with a hemacytometer.
General anesthesia in rats is induced with inhaled enflurane, wherein a suitable amount of the Aspergillus spore suspension (i.e., 0.1 mL to deliver 10⁶spores) is injected with a syringe to the exposed trachea. Wounds are closed surgical staples.
The rats are administered the formulations of caspofungin as described above with an inhalation device, such as a jet nebulizer or an ultrasonic nebulizer, in a glass chamber. Rats are treated at an appropriate time point before infection, such as 48 hours. The estimated amount of drug inhaled by the rats is calculated from the concentration of the product in the chamber, the minute volume of the rats (lung volume times respiratory rate), and exposure time.
For trial 1, rats (8-10 rats in each group) are either treated with a placebo, such as sterile water, or with a suitable dose of caspofungin at a suitable time period before infection (i.e., 48 hours). Immunosuppressive treatments with cortisone acetate are discontinued after time of infection. Rats in this group are monitored for survival on daily basis for an appropriate amount of time (i.e., 7 days).
For trial 2, rats (8-10 rats in each group) are either treated with a placebo, such as sterile water or with an appropriate dose of caspofungin at a suitable time period before infection (i.e., 48 hours). Immunosuppressive treatments with cortisone acetate are continued for the duration of the experiment after infection (i.e., 14 days).
The outcome variables used to assess efficacy of this study include but are not limited: survival of the infected rats during therapy and after termination of therapy and caspofungin concentration in the lung tissue and other organs (liver, kidney, spleen, and pancreas) and plasma.

Example 4: Antifungal Efficacy of Caspofungin in Treatment of Experimental Pulmonary Aspergillosis in Transiently Neutropenic Rats

The objective of the study is to determine the antifungal efficacy of the caspofungin formulations administered via inhalation therapy in the treatment of invasive pulmonary aspergillosis in transiently neutropenic rats.
The experimental procedures are performed according to the procedures described in van de Sande et. al., Antimicrob. Agents Chemother. 2008, 52, 1345-1350 with further modifications.
The caspofungin formulation used herein include any one of the formulations as described herein, such as those from Example 1, or any one of the following formulations: Formulation 1: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N²-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B₀diacetate) (i.e. 50 mg or 70 mg), sucrose (i.e 34 mg or 54 mg), glacial acetic acid, sodium hydroxide; and Formulation 2: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N2-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B0 diacetate), glacial acetic acid, sodium hydroxide.
A clinical strain of Aspergillus fumigatus is obtained from a hemato-oncological patient with pulmonary aspergillosis. The strain is passed through neutropenic rats and maintained on Sabourand agar slants in order to maintain the strain's virulence. The minimal inhibitory concentration (MIC) and minimal effective concentration (MEC) of the strain used for this experiment against caspofungin are determined accordingly.

Infection Model and Antifungal Treatment

The rat model of aerogenic left-sided invasive pulmonary aspergillosis as described in van de Sande et. al., Antimicrob. Agents Chemother. 2008, 52, 1345-1350 is used. Neutropenia is induced by intraperitoneal administration of a suitable dose of cyclophosphamide, such as 75 mg/kg, and is administered before inoculation (i.e., 5 days) followed by administration of a suitable dose prior to inoculation (i.e., 60 mg/kg 1 day before inoculation) and several doses following inoculation (i.e., 50, 40, and 30 mg/kg on days 3, 7, and 11 after fungal inoculation).
Fungal infection is established by intubation of the left main bronchus while the rats are under general anesthesia. A cannula is passed through the tube, and the left lobe is inoculated with the appropriate amount of aspergillosis, such as 6×10⁴conidia.
Antifungal therapy is initiated at a suitable time point after inoculation, such as 16 h, 24 h, or 72 h after inoculation. The rats are administered the formulations of caspofungin as described above with an inhalation device, such as a jet nebulizer or an ultrasonic nebulizer, in an appropriate dose (i.e., 4 mg/kg or 10 mg/kg) and suitable dosing schedule, such as once a day, once every two days, or once every three days. The antifungal therapy is continued for a suitable amount of time, such as 7 days, 14 days, or 21 days.
Outcome Variables
The outcome variables used to assess efficacy include but not limited to following: survival of the infected rats during therapy and after termination of therapy, pulmonary infarct score, lung weight, residual, fungal burden (log CFU/gram), fungal growth (log CFU/gram) in bronchoalveolar lavage fluid, computerized tomograph (CT) scores, galactamannan index (GMI), and histopathology.

The caspofungin formulation used herein include any one of the formulations as described herein, such as those from Example 1, or any one of the following formulations: Formulation 1: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N²-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B₀diacetate) (i.e. 50 mg or 70 mg), sucrose (i.e 34 mg or 54 mg), glacial acetic acid, sodium hydroxide; and Formulation 2: caspofungin acetate (4R,5S)-5-[(2-aminoethyl)amino]-N2-(10,12-dimethyl-loxotetradecyl)-4-hydroxy-L-ornithine]-5-[(3R)-3-hydroxy-L-ornithine] pneumocandin B0 diacetate), glacial acetic acid, sodium hydroxide.
To assess the efficacy of caspofungin inhalation therapy for the prophylaxis of pulmonary aspergillosis in a transiently neutropenic rat model, the same methods used for the assessing the therapeutic efficacy as described in Example 4 are utilized with the following exceptions: caspofungin administration via inhalation is started at a suitable time period before inoculation (i.e., 24 to 48 hours before infection); and a lower load of administered inoculum is administered in order to simulate the low initial tissue burden of A. fumigatus. Similar outcome variables as described in Example 4 are used to assess efficacy.
