RELATED APPLICATIONS
[0001] The present application claims priority under 35 U.S.C. 119(e) to United States Provisional Patent Application Number 60/603,761 filed August 23, 2004.
FIELD OF THE INVENTION
[0002] This invention is generally in the field of drug delivery related to both small molecule and macromolecular drugs. More particularly it is related to 2,5-diketopiperazine salts, their use in the formulation of such drugs including therapeutic, prophylactic and diagnostic agents, stabilizing agents and systems for their delivery.
BACKGROUND TO THE INVENTION
BACKGROUND TO THE INVENTION
[0003] Drug delivery has been a persistent challenge in the pharmaceutical arts, particularly when a drug is unstable and/or poorly absorbed at the locus in the body to which it is administered. One such class of drugs includes 2,5-diketopiperazines, which is represented by the compound of the general Formula 1 as shown below where E=N.
R2 El 0 O E2 R, Formula 1 These 2,5 diketopiperazines have been shown to be useful in drug delivery, particularly those bearing acidic R groups (see for example U.S. Patent Nos. 5,352,461 entitled "Self Assembling Diketopiperazine Drug Delivery System;" 5,503,852 entitled "Method For Making Self-Assembling Diketopiperazine Drug Delivery System;" 6,071,497 entitled "Microparticles For Lung Delivery Comprising Diketopiperazine;" and 6,331,318 entitled "Carbon-Substituted Diketopiperazine Delivery System," each of which is incorporated herein by reference in its entirety for all that it teaches regarding diketopiperazines and diketopiperazine-mediated drug delivery). Diketopiperazines can be formed into particles that incorporate a drug or particles onto which a drug can be adsorbed. The combination of a drug and a diketopiperazine can impart improved drug stability. These particles can be administered by various routes of administration. As dry powders these particles can be delivered by inhalation to specific areas of the respiratory system, depending on particle size.
Additionally, the particles can be made small enough for incorporation into an intravenous suspension dosage form. Oral delivery is also possible with the particles incorporated into a suspension, tablets or capsules; or dissolved in an appropriate solvent.
Diketopiperazines may also facilitate absorption of an associated drug. Nonetheless difficulties can arise when diketopiperazines are diacids, or are in diacid form(s), due to the limited solubility of these diacids at non-basic pH (i.e., neutral or acid pH). Another difficulty arises because these diacid diketopiperazines may form disadvantageous association(s) with some drugs.
R2 El 0 O E2 R, Formula 1 These 2,5 diketopiperazines have been shown to be useful in drug delivery, particularly those bearing acidic R groups (see for example U.S. Patent Nos. 5,352,461 entitled "Self Assembling Diketopiperazine Drug Delivery System;" 5,503,852 entitled "Method For Making Self-Assembling Diketopiperazine Drug Delivery System;" 6,071,497 entitled "Microparticles For Lung Delivery Comprising Diketopiperazine;" and 6,331,318 entitled "Carbon-Substituted Diketopiperazine Delivery System," each of which is incorporated herein by reference in its entirety for all that it teaches regarding diketopiperazines and diketopiperazine-mediated drug delivery). Diketopiperazines can be formed into particles that incorporate a drug or particles onto which a drug can be adsorbed. The combination of a drug and a diketopiperazine can impart improved drug stability. These particles can be administered by various routes of administration. As dry powders these particles can be delivered by inhalation to specific areas of the respiratory system, depending on particle size.

Diketopiperazines may also facilitate absorption of an associated drug.

Another difficulty arises because these diacid diketopiperazines may form disadvantageous association(s) with some drugs.
[0004] Therefore there is a need for diketopiperazine compositions having greater solubility at a neutral and/or acidic pH and methods for their use in the manufacture of therapeutic compositions.

These microparticles include microcapsules, which have an outer shell composed of either the heterocyclic compound alone or in combination with one or more drug(s). This outer shell may surround a core material. This outer shell may also surround or constitute microspheres that are either solid or hollow, or a combination thereof, which contain one or more drugs dispersed throughout the sphere and/or adsorbed onto the surface of the sphere. The outer shell also may surround microparticles having irregular shape, either alone or in combination with the aforementioned microspheres.
[0053] In a preferred embodiment for pulmonary delivery, the microparticles are from about 0.1 microns to about ten microns in diameter. Within drug delivery systems, these microparticles exhibit desirable size distributions as well as good cargo tolerance.
[0054] The heterocyclic compounds of the present invention include, without limitation, diketopiperazines, diketomorpholines and diketodioxanes and their substitution analogs.
These heterocyclic compositions comprise rigid hexagonal rings with opposing heteroatoms and unbonded electron pairs. The general formula for diketopiperazine and its analogs is shown below in the compound of Formula 1.
R2 El 0 O E2 R, Formula 1 [0055] In the compound of Formula 1 the ring atoms E, and E2 at positions 1 and 4 are either 0 or N. At least one of the side-chains R, and R2 located at positions 3 and 6 respectively contains a carboxylate group (i.e., OR). In one embodiment of the present invention these carboxylate groups are located along the side chains (R, and/or R2) as pendent groups, in another embodiment the carboxylate is located intra-chain (an ester) and yet in another embodiment the carboxylate groups are terminal.
[0056] General methods for the synthesis of diketopiperazines are known in the art and have been described in United States Patent Nos. 5,352,461, 5,503,852, and 6,331,318 which have been cited and incorporated herein by reference above. In a preferred embodiment of the invention the diketopiperazine is a derivative of 3,6-di(4-aminobutyl)-2,5-diketopiperazine, which may be formed by condensation of the amino acid lysine.
Exemplary derivatives include 3,6-di(succinyl-4-aminobutyl)- (succinyl diketopiperazine or SDKP), 3,6-di(maleyl-4-aminobutyl)-, 3,6-di(citraconyl-4-aminobutyl)-, 3,6-di(glutaryl-4-aminobutyl)-, 3,6-di(malonyl-4-aminobutyl)-, 3,6-di(oxalyl-4-aminobutyl)-, and 3,6-di(fumaryl-4-aminobutyl)-2,5-diketopiperazine (hereinafter fumaryl diketopiperazine or FDKP).
Additionally, nonsymmetrical derivatives of the aforementioned compounds are also contemplated. However, it is specifically noted herein that the lithium salts of 2,5-diaspartyl-3,6-diketopiperazine and 2,5-diglutamyl-3,6-diketopiperazine are not considered within the scope of the present invention and as such are hereby specifically disclaimed.

The compound of Formula 3 will be referred to hereinafter as 2,5-diglutamyl-3,6-diketopiperazine. It is understood that all other heterocyclic compounds based on Formula 1 are considered within the scope of the present invention.
[0058] For exemplary purposes, diketopiperazines salts and their derivatives will be described in detail. These compounds are the preferred embodiments of the present invention. However, this does not exclude other heterocyclic compounds based on the compound of Formula 1.
[0059] The use of DKP salts for the delivery of phosphodiesterase type 5-inhibitors is described in co-pending U.S. Patent Application No. XX/XXX,XXX filed August 23, 2005 and entitled "Pulmonary Delivery of Inhibitors of Phosphodiesterase Type 5" and known to all by U.S. Provisional Patent Application No. 60/603,764, which is hereby incorporated by reference in its entirety. Pulmonary drug delivery using DKP microparticles is disclosed in U.S. Patent No. 6,428,771 entitled "Method For Drug Delivery To The Pulmonary System", which is hereby incorporated by reference in its entirety.
[0060] Diketopiperazine facilitate transcellular transport of biologically active agents across biological tissues however they are not penetration enhancers.
Penetration enhancers are compounds that improve drug movement across biological tissues by disrupting cell membranes. Examples of penetration enhancers are surfactants and soaps.
Diketopiperazines do not disrupt cell membranes either in vitro or in vivo. In vitro studies demonstrate that FDKP does not disrupt cell membranes or tight junctions and does not compromise cell viability. Diketopiperazine/insulin powder compositions are soluble at the physiological pH of the lung surface and dissolve rapidly after inhalation.
Once dissolved, the DKP facilitates passive transcellular transport of the insulin.
[0061] Applicants have discovered improved diketopiperazine compositions having greater solubility at a neutral and/or acidic pH. Applicants have also discovered that therapeutic complexes between improved diketopiperazines and drug(s) of interest can be formed.
[0062] The salts of the present invention can be prepared by reacting the diketopiperazine free acid with a solution of an appropriate base as described in Examples 1 and 2 below. In a preferred embodiment, the salt is a pharmaceutically acceptable salt such as the sodium (Na), potassium (K), lithium (Li), magnesium (Mg), calcium (Ca), ammonium, or mono-, di- or tri-alkylammonium (as derived from triethylamine, butylamine, diethanolamine, triethanolamine, or pyridines, and the like) salts of diketopiperazine, for example. The salt may be a mono-, di-, or mixed salt. Higher order salts are also contemplated for diketopiperazines in which the R groups contain more than one acid group.
In other aspects of the invention, a basic form of the agent may be mixed with the DKP in order to form a drug salt of the DKP, such that the drug is the counter cation of the DKP.
[0063] For drug delivery, biologically active agents or drugs having therapeutic, prophylactic, or diagnostic activities can be delivered using diketopiperazines. Essentially, the biologically active agent is associated with the diketopiperazine particles of the present invention. As used herein, "associated" means a biologically active agent-diketopiperazine composition formed by, among other methods, co-precipitation, spray drying or binding (complexation) of the diketopiperazine with the biologically active agent. The resulting diketopiperazine particles include those that have entrapped, encapsulated and/or been coated with the biologically active agent. While the exact mechanism of association has not been conclusively identified, it is believed that the association is a function of physical entrapment (molecular entanglement) in addition to electrostatic attraction including hydrogen bonding, van der Waal's forces and adsorption.
[0064] The biologically active agents that can be associated with the diketopiperazine particles of the present invention include, but are not limited to, organic or inorganic compounds, proteins, or a wide variety of other compounds, including nutritional agents such as vitamins, minerals, amino acids, carbohydrates, sugars, and fats. In preferred embodiments, the drugs include biologically active agents that are to be released in the circulatory system after transport from the GI tract following oral delivery.
In other preferred embodiments the materials are biologically active agents that are to be released in the circulatory system following pulmonary or nasal delivery. In other preferred embodiments the materials are biologically active agents that are to be release in the central nervous system following nasal delivery. Additionally, the drug can be absorbed through mucosal tissue such as rectal, vaginal, and/or buccal tissue. Non-limiting examples of biologically active agents include proteins and peptides (wherein protein is defined as consisting of 100 amino acid residues or more and a peptide is less than 100 amino acid residues), such as insulin and other hormones, polysaccharides, such as heparin, nucleic acids (such as plasmids, oligonucleotides, antisense, or siRNA), lipids and Iipopolysaccharides, and organic molecules having biological activity such as many of the antibiotics, anti-inflammatories, vasoactive agents (including agents used to treat erectile dysfunction) and neuroactive agents. Specific non-limiting examples include steroids, hormones, decongestants, anticoagulants, immunomodulating agents, cytotoxic agents, antibiotics, antivirals, anesthetics, sedatives, antidepressants, cannabinoids, anticoagulants, antisense agents, antigens, and antibodies. In some instances, the proteins may be antibodies or antigens which otherwise would have to be administered by injection to elicit an appropriate response.
More particularly, compounds that can be associated with the diketopiperazine compositions of the present invention include insulin, heparins, calcitonin, felbamate, parathyroid hormone and fragments thereof, growth hormone, erythropoietin, glucagon-like peptide-1, somatotrophin-releasing hormone, follicle stimulating hormone, cromolyn, adiponectin, RNAse, ghrelin, zidovudine, didanosine, tetrahydrocannabinol (i.e., cannabinoids), atropine, granulocytes colony stimulating factor, lamotrigine, chorionic gonadotropin releasing factor, luteinizing releasing hormone, beta-galactosidase and Argatroban. Compounds with a wide range of molecular weight can be associated, for example, between 100 and 500,000 grams per mole.
[0065] Imaging agents including metals, radioactive isotopes, radiopaque agents, and radiolucent agents, can also be incorporated into diketopiperazine delivery systems.
Radioisotopes and radiopaque agents include gallium, technetium, indium, strontium, iodine, barium, and phosphorus.
[0066] Additionally the drugs can be in various forms, such as uncharged molecules, metal or organic salts, or prodrugs. For acidic drugs, metal salts, amines or organic cations (e.g., quaternary ammonium) can in some cases be used.
[0067] In some embodiment, the drugs include biologically active agents that are to be released in the circulatory system after transport from the gastrointestinal tract following oral delivery. In other embodiments, the biologically active agents are to be released in the circulatory system following pulmonary or nasal delivery. In still other embodiments, the biologically active agents are to be released in the central nervous system following nasal delivery. Additional, the drugs can be absorbed through mucosal tissue such as rectal, vaginal, and/or buccal tissue.
[0068] Some of these biological agents are unstable in gastric acid, diffuse slowly through gastrointestinal membranes, are poorly soluble at physiological pH, and/or are susceptible to enzymatic destruction in the gastrointestinal tract. The biological agents are combined with the diketopiperazine salts to protect them in the gastrointestinal tract prior to release in the blood stream. In a preferred embodiment the diketopiperazines are not biologically active and do not alter the pharmacologic properties of the therapeutic agents.
[0069] To associate one or more drugs with a DKP salt, the drug and the DKP
salt are preferably mixed in solution or suspension and subsequently dried. Either component may be present as solute or suspendate. In different embodiments the mixture is spray dried or lyophilized.
[0070] Spray drying is a thermal processing method used to form, load or dry particulate solids from a variety of solutions or suspensions. The use of spray drying for the formation of dry particulate pharmaceuticals is known in the art however in the past its use had been limited by its incompatibility with biological macromolecular drugs, including protein, peptides and nucleic acids due to the nature of the spray drying process. During spray drying, a solution or suspension is formed into droplets through aerosolization and, then passed through a heated gas stream having sufficient heat energy to evaporate water and solvents in the particles to a desired level before the particles are collected. The inlet temperature is the temperature of the gas stream leaving its source and its level is selected based upon the lability of the macromolecule being treated. The outlet temperature is a function of the inlet temperature, the heat load required to dry the product along with other factors.
[0071] The present inventors have unexpectedly determined that the particles of the present invention, have aerodynamic performance which improves with increasing content of a biologically active agent which has not been seen with other particles. The respirable fraction (%rf), the percentage of particles between 0.5 and 5.8 microns in diameter, of the spray dried particles of the present invention increases with increasing insulin content, rather than decreasing as was expected. Therefore using the methods of the present invention, diketopiperazine microparticies can be formed which have higher biologically active agent content that was previously achievable.
[0072] Additionally, the present inventors have surprisingly determined that spray dried FDKP disodium salt/insulin compositions have increased insulin stability as the concentration of the FDKP disodium salt in the starting solution increases.
Stability was measured by insulin loss after 17 days at 40 C/75 /a relative humidity. For example, 8.5%
insulin was lost from powder spray dried from a solution containing 37 mg/mL
solids (total weight of FDKP disodium salt/insulin). By comparison, 4.5% insulin was lost from powder spray dried from a solution containing 45 mg/mL solids and 2.7% insulin was lost from powder spray dried from a solution containing 67 mg/mL solids.
[0073] In a further observation, inlet temperature was found to have surprising effects on insulin stability. The data indicate that insulin stability in the powder increases with increasing inlet temperature as measured by insulin loss after 17 days at 40 /75% RH. For example, about 4% insulin was lost from powder spray dried at an inlet temperature of 180 C. By comparison, <1% insulin was lost from powder spray dried at an inlet temperature of 200 C.
[0074] In an embodiment of the present invention, microparticles suitable for delivery to the pulmonary system are provided wherein the microparticles have a rugosity of less than 2. Another aspect of the present invention influenced by spray drying is the particle morphology, measured by rugosity, which the ratio of the specific area and the surface area calculated from the particle size distribution and particle density. The drying operation may be controlled to provide dried particles having particular characteristics, such as rugosity.
Rugosity of spray dried particles is a measure of the morphology of the surface of the particles, such as the degree of folding or convolution.
[0075] It had previously been thought that a rugosity above 2 was needed in order to obtain particles with sufficient dispersability to form a free-flowing powder.
Surprisingly, the present inventors have produced particles suitable for pulmonary delivery with a rugosity below 2 [0076] The microparticle formulations of the present invention can be administered as a liquid or solid form. These can include solutions, suspensions, dry powders, tablets, capsules, suppositories, patches for transdermal delivery, and the like. These different forms offer distinct, but overlapping, advantages. The solid forms provide convenient bulk transport of drugs and can improve their stability. They can also be formed into microparticles enabling administration by inhalation specifically to the nasal mucosa or deep lung, depending on the size of the microparticle. Diketopiperazines can also facilitate absorption of the associated drug even when delivered as a solution. Some of the DKP salts (for example, the sodium and potassium salts) offer improved solubility at neutral and acidic pH as compared to the free acid, which can lead to improved absorption in the stomach of orally administered solid forms.
[0077] Dikeopiperazine salt counter cations may be selected to produce salts having varying solubilities. These varying solubilities can be the result of differences in dissolution rate and/or intrinsic solubility. By controlling the rate of DKP salt dissolution, the rate of drug absorption from the DKP salt/drug combination can also be controlled to provide formulations having immediate and/or sustained release profiles. For example, sodium salts of organic compounds are characteristically highly soluble in biological systems, while calcium salts are characteristically only slightly soluble in biological systems. Thus, a formulation comprised of a DKP sodium salt/drug combination would provide immediate drug absorption, while a formulation comprised of a DKP calcium salt/drug combination would provide slower drug absorption. A formulation containing a combination of both of the latter formulations could be used to provide immediate drug absorption followed by a period of sustained absorption.
[0078] Diketopiperazine salt formulations of biologically active agents may be administered orally. Microparticles, depending on the chemical nature and size, are absorbed through the epithelial lining of the gastrointestinal tract into the bloodstream or lymphatic system. Alternatively, the composition can be administered as a solution in which the DKP salt serves to facilitate the absorption of the drug. Additionally, the microparticles can be administered as a suspension or a solid dosage form that dissolves completely and is absorbed following dissolution.
[0079] For parenteral administration, microparticles of less than five microns readily pass through a needle for intravenous administration. Suitable pharmaceutical carriers, for example, phosphate buffered saline, are known and commercially available.
Similarly, microparticles can be injected or implanted subcutaneously, intramuscularly, or intraperitoneally. Additionally, the microparticles can be placed in an implantable device to facilitate sustained and/or controlled delivery.
[0080] For topical or transdermal administration, microparticles can be suspended in a suitable pharmaceutical carrier for administration using methods appropriate for the carrier and site of administration. For example, microparticles are administered to the eye in a buffered saline solution, at a pH of approximately 7.4, or in an ointment such as mineral oil.
The dosage will be dependent on the compound to be released as well as the rate of release. The microparticles, or aggregations of microparticles into films, disks, or tablets, with incorporated compound can be administered to the skin in an ointment, cream, or patch.
Suitable pharmaceutical carriers are known to those skilled in the art and commercially available. Mucosal administration, including buccal, vaginal, rectal, nasal administration is also contemplated.
[0081] Pulmonary delivery can be very effectively accomplished using dry powders comprising the microparticles of the invention and can lead to rapid absorption into the circulation (bloodstream). Dry powder inhalers are known in the art and particularly suitable inhaler systems are described in U.S. patent application nos. 09/621,092 and 10/655,153, both entitled "Unit Dose Capsules and Dry Powder Inhaler", which are hereby incorporated by reference in their entirety. Information on pulmonary delivery using microparticles comprising diketopiperazine can be found in U.S. Patent No. 6,428,771 entitled "Method for Drug Delivery to the Pulmonary System," which is hereby incorporated by reference in its entirety. The following examples are meant to illustrate one or more embodiments of the invention and are not meant to limit the invention to that which is described below.

The material was suspended in 75 mL of deionized water. Insulin (0.84 g) was added to the FDKP salt suspension. The resulting slurry was titrated to a pH of 8.3 with NH4OH to form a solution. The FDKP disodium salt and insulin solution was brought to a volume of 100 mL with deionized water and filtered through a 0.22 pm polyethersulfone membrane.

Insulin (1.68 g) was added to the FDKP salt suspension. The resulting slurry was titrated to a pH of 8.3 with NH4OH to form a solution. The FDKP disodium salt and insulin solution was brought to a volume of 100 mL with deionized water and filtered through a 0.22 pm polyethersulfone membrane. The solution was spray-dried using a BUCHI Mini Spray Dryer B-191 (Buchi Labortechnik AG, Switzerland) under the following conditions.

Example 8. Characterization of Disodium FDKP-Insulin Microparticles [0089] The microparticles described in Examples 6 and 7 were subjected to laser diffraction particle size analysis (SympatecGmbH, Germany) (FIGs. 1A and 1B).
The particles of Example 6 displayed an average respirable fraction (according to the USP
definition of 0.5 to 5.8 microns) of 87.93% with a standard deviation of 1.60 and a %CV
(coefficient of variation) of 1.82. The particles of Example 7 displayed an average respirable fraction of 81.36% with a standard deviation of 4.20 and a %CV of 5.16.
Example 9. Pulmonary Administration of Disodium FDKP-Insulin [0090] A dry powder containing the disodium FDKP salt and insulin is inhaled at the beginning of meal. The particles that comprise the dry powder are preferably in the range of approximately 0.5 - 5.8 microns in size. The exact dosage is patient-specific, but generally on the order of 5-150 Units of insulin per dose. The insulin absorption from this dosage regimen mimics physiologic first-phase insulin release, and attenuates post-prandial blood glucose excursions.
Example 10. Preparation of an Oral Dosage Form [0091] Spray-dried disodium FDKP/insulin powder as described in Examples 6 or 7 is packed into hard gelatin capsules. The capsules can contain approximately 50-100 mg of powder. The FDKP salt/insulin powders prepared in Examples 6 and 7 were 25%
insulin by weight and insulin activity was about 26 units/mg. Thus, 50 mg would be on the order of 1300 units, significantly larger than a typical dose. About 2-30 mg of the FDKP salt/insulin powder is mixed with methyl cellulose (other bulking agents are well known in the art) to make up the balance of the desired mass.
Example 11. Oral Administration of Disodium FDKP-Insulin [0092] Capsules containing the FDKP salt and insulin are taken before a meal.
The exact dosage is patient-specific, but generally on the order of approximately 10-150 units of insulin is administered per dose. The subsequent insulin absorption attenuates post-prandial blood glucose excursions. This oral insulin formulation is used to replace pre-meal insulin injections in patients with diabetes. Additionally, insulin absorbed through the gastrointestinal tract mimics endogenous insulin secretion. Endogenous insulin is secreted by the pancreas into the portal circulation. Insulin absorbed following oral administration also goes directly to the portal circulation. Thus, the oral route of insulin administration delivers insulin to its site of action in the liver, offering the potential to control glucose levels while limiting systemic exposure to insulin. Oral insulin delivery using a combination of insulin and the diacid form of FDKP is hindered by the poor solubility of the FDKP diacid in the low pH environment of the gastrointestinal tract. The FDKP salts, however, provide a local buffering effect that facilitates their dissolution in low pH.
Example 12. Preparation C of FDKP Di-Sodium Salt [0093] Fifty grams of fumaryl diketopiperazine (FDKP, 221.01 mmol, 1 equiv.), water (200 mL), and 10 N sodium hydroxide (21.9 mL, 437.61 mmol, 1.98 equiv.) were charged to a 1-liter, 4-neck, round bottom flask equipped with a reflux condenser, o.verhead stirrer, nitrogen inlet, and thermometer. The mixture was heated to 50 C to achieve a yellow solution and ethanol (650 mL) was added over 15 minutes. When the addition was complete, the slurry was held at 50 C for 30 - 60 minutes. The reaction mixture was vacuum filtered and the isolated solids were washed with ethanol (150 mL) and acetone (150 mL x 2) then dried in a vacuum oven (50 C, 30 inches of mercury) overnight. No further purification was required. The salt was assayed for moisture content (Karl Fischer) and sodium content (elemental analysis and titration). The yield of the salt was from about 90%
to about 95%.

Example 13: FDKP salt/insulin powder prepared by spray drying [0095] The disodium salt of FDKP (5 g) was dissolved in deionized water (150 mL) and insulin (1.69 g) was added. The pH of the suspension was adjusted to 8.3 with ammonium hydroxide (NH4OH) to give a solution that was subsequently diluted to 200 mL
with deionized water and filtered. The solution was spray dried using the following conditions:
Inlet temperature - 200 C
Outlet temperature - 80 C
Atomization gas - 600 liter N2/hr Process gas - 80% of maximum The spray nozzle was cooled to 28 C
[0096] The resultant particles were analyzed for their aerodynamic properties and the data are reported in Table 3.

A representative SEM is shown in Figure 3. The particle morphology is consistent with a collapsed hollow sphere.
[0100] The stability of the disodium salt/insulin particles was evaluated under accelerated room temperature conditions (40 /75% relative humidity [RH]).
Compared to a control formulation prepared by lyophilization, the spray-dried particles demonstrated superior insulin stability as measured by insulin degradation (Figure 4).
[0101] The starting concentration of the FDKP disodium salt/25%insulin solution prior to spray drying was evaluated for its effect on final particle stability. The data (Figure 5) shows that insulin stability on the particle increases with increasing solution concentrations as measured by insulin loss after 17 days at 40 /75% RH.
Example 14. Solvent/anti-solvent precipitation of a solution of FDKP
salt/insulin with an organic solvent [0102] The precipitation was controlled using harmonic ultrasonic atomization.
Alternate cavitation methods as well as high shear mixing and homogenization are also applicable.
[0103] The disodium salt of FDKP (5 g) was dissolved in deionized water (80 mL).
Insulin (0.65 g) was added to the solution to produce a suspension. The pH of the suspension was adjusted to 8.3 with NH4OH to obtain a solution that was diluted to 100 mL
with deionized water and filtered. The particles were precipitated by pumping the insulin/disodium salt of FDKP solution and ethanol in a 1:5 ratio through a duel inlet atomization horn vibrating at a frequency between 20 kHz and 40 kHz. The precipitate was collected in a media bottle containing ethanol (200 mL). Post-precipitation the material was washed with ethanol and dried via rotary evaporation or by bubbling nitrogen through the suspension. The particles contained 12.5% insulin by weight. Particle morphology was evaluated by SEM (Figure 6).
[0104] The particles illustrated in FIG. 6A (10k x) and FIG. 6B (20K x) are in the 1 to 5 micron range while at lower magnification (FIG. 6C, 2.5k x and FIG. 6D, 1.0k x) particles in the 10 to 40 micron range are seen. It is the non-binding hypothesis of the present inventors that the drying methods utilized in this study resulted in recrystalization of the primary particles into much larger secondary particles and that the use of a method that maintains a constant ratio of organic to aqueous components throughout the drying process, such as spray drying, can preserve the primary particles to the exclusion of the formation of a significant number of secondary particles.
Example 15. In situ diammonium salt formation and formulation.
[0105] FDKP or SDKP (succinyl DKP) diammonium salt/insulin particles were formed by spray drying. A representative procedure is given for the FDKP ammonium salt/insulin formulation containing 25% insulin.
[0106] FDKP (5 g) was suspended in deionized water (150 mL) and titrated to a pH of 7.5 to 8.0 with ammonium hydroxide (NH4OH). Insulin (1.69 g) was added to the resulting solution (FDKP) to give a suspension. The pH of the suspension was adjusted to 8.3 with ammonium hydroxide (NH4OH) to give a solution that was diluted to 200 mL with deionized water and filtered. The powder was produced by spray drying the solution under the following conditions.
Inlet temperature - 200 C
Outlet temperature - 80 C
Atomization gas - 600 liter N2/hr Process gas - 80% of maximum The spray nozzle was cooled to 28 C
[0107] The %rf of the diammonium salts is about 10% higher than the %rf of the disodium salt. The counter cation has a large effect on particle performance.
Also, the 50%
FDKP ammonium salt/insulin powder has a %rf comparable to that of the corresponding 25% FDKP ammonium salt/insulin powder. This is surprising because with the powders prepared by lyophilization from the FDKP free acid, the %rf decreases as the insulin content increases.
[0108] The resultant particles were analyzed for their aerodynamic properties and the data are reported in Table 5.

[0113] Scanning electron microscopy was utilized to study particle morphology.
Representative SEMs are shown in the Figure 10 (FDKP) and Figure 11 (SDKP).
The particle morphology is consistent with a collapsed hollow sphere.
[0114] The stability of the in situ salt formation and formulation of the diammonium salt/insulin particles was evaluated under accelerated room temperature conditions (40 /75%
RH). Compared to a control formulation prepared by lyophilization, the spray dried particles demonstrated superior insulin stability as measured by insulin degradation (FDKP, Figure 12 and SDKP, Figure 14) and formation of the desamino degradrant (A21) (FDKP, Figure 13 and SDKP, Figure 15).
Example 16. Characteristics of Spray Dried Microparticles.
[0115] Spray dried FDKP salt/insulin particles demonstrate a surprising and unexpected trend in aerodynamic performance. Previously observed insulin-containing microparticles, which had been formed from DKP free acid microparticles onto which insulin had been loaded and the solvent removed by lyophilization, demonstrated decreased aerodynamic performance with increasing insulin content. For example, the %rf (respirable fraction) for 25% loaded particles was significantly lower than the %rf for 5%
loaded particles. For spray dried FDKP salt microparticles containing insulin, the opposite trend is observed. As insulin load increases, %rf increases.
[0116] Spray dried powders of the FDKP disodium salt were prepared with insulin contents of 11.4%, 50.0%, 70.0%, or 90.0% (w:w). Figure 16 shows that %rf increases with increasing insulin load.
[0117] A similar trend was also observed in spray dried FDKP diammonium salt/insulin powders having insulin contents of 11.4%, 50.0%, 70.0%, or 90.0% (w:w). The %rf increased with insulin load (Figure 17).
[0118] The starting concentration of the FDKP disodium salt solution prior to spray drying was evaluated for its effect on final particle insulin stability. The data indicate that insulin stability in the powder increases with increasing solution concentrations as measured by insulin loss after 17 days at 40 /75% RH. For example, 8.5% insulin was lost from powder spray dried from a solution containing 37 mg/mL solids. By comparison, 4.5%
insulin was lost from powder spray dried from a solution containing 45 mg/mL
solids and 2.7% insulin was lost from powder spray dried from a solution containing 67 mg/mL solids.
[0119] The inlet temperatures used to spray dry solutions of the FDKP disodium salt and insulin to form particles containing 50% insulin was evaluated for its effect on final particle insulin stability. The data indicate that insulin stability in the powder increases with increasing inlet temperature as measured by insulin loss after 17 days at 40 /75% RH. For example, about 4% insulin was lost from powder spray dried at an inlet temperature of 180 C. By comparison, <1% insulin was lost from powder spray dried at an inlet temperature of 200 C.
[0120] Additionally, the present inventors have unexpected found that these particles, which are suitable for pulmonary delivery, have a rugosity of approximately 1.

DETAILED DESCRIPTION OF THE INVENTION
[0051] The present invention provides improved drug delivery systems comprising carboxylate salts of heterocyclic compounds in combination with one or more drugs. In one embodiment of the present invention the heterocyclic compounds form microparticles that incorporate the drug or drugs to be delivered. These microparticies include microcapsules, which have an outer shell composed of either the heterocyclic compound alone or in combination with one or more drugs. The heterocyclic compounds of the present invention include, without limitation, diketopiperazines, diketomorpholines and diketodioxanes and their substitution analogs. The heterocyclic compositions of the present invention comprise rigid hexagonal rings with opposing heteroatoms and unbonded electron pairs.
[0052] One aspect of the present invention includes a drug delivery system comprising the carboxylate salts of heterocyclic compounds in combination with one or more drugs. In one embodiment of the present invention the heterocyclic compounds form microparticies that incorporate the drug or drugs to be delivered. These microparticles include microcapsules, which have an outer shell composed of either the heterocyclic compound alone or in combination with one or more drug(s). This outer shell may surround a core material. This outer shell may also surround or constitute microspheres that are either solid or hollow, or a combination thereof, which contain one or more drugs dispersed throughout the sphere and/or adsorbed onto the surface of the sphere. The outer shell also may surround microparticles having irregular shape, either alone or in combination with the aforementioned microspheres.
[0053] In a preferred embodiment for pulmonary delivery, the microparticles are from about 0.1 microns to about ten microns in diameter. Within drug delivery systems, these microparticles exhibit desirable size distributions as well as good cargo tolerance.
[0054] The heterocyclic compounds of the present invention include, without limitation, diketopiperazines, diketomorpholines and diketodioxanes and their substitution analogs.
These heterocyclic compositions comprise rigid hexagonal rings with opposing heteroatoms and unbonded electron pairs. The general formula for diketopiperazine and its analogs is shown below in the compound of Formula 1.
R2 El 0 O E2 R, Formula 1 [0055] In the compound of Formula 1 the ring atoms E, and E2 at positions 1 and 4 are either 0 or N. At least one of the side-chains R, and R2 located at positions 3 and 6 respectively contains a carboxylate group (i.e., OR). In one embodiment of the present invention these carboxylate groups are located along the side chains (R, and/or R2) as pendent groups, in another embodiment the carboxylate is located intra-chain (an ester) and yet in another embodiment the carboxylate groups are terminal.
[0056] General methods for the synthesis of diketopiperazines are known in the art and have been described in United States Patent Nos. 5,352,461, 5,503,852, and 6,331,318 which have been cited and incorporated herein by reference above. In a preferred embodiment of the invention the diketopiperazine is a derivative of 3,6-di(4-aminobutyl)-2,5-diketopiperazine, which may be formed by condensation of the amino acid lysine.
Exemplary derivatives include 3,6-di(succinyl-4-aminobutyl)- (succinyl diketopiperazine or SDKP), 3,6-di(maleyl-4-aminobutyl)-, 3,6-di(citraconyl-4-aminobutyl)-, 3,6-di(glutaryl-4-aminobutyl)-, 3,6-di(malonyl-4-aminobutyl)-, 3,6-di(oxalyl-4-aminobutyl)-, and 3,6-di(fumaryl-4-aminobutyl)-2,5-diketopiperazine (hereinafter fumaryl diketopiperazine or FDKP).
Additionally, nonsymmetrical derivatives of the aforementioned compounds are also contemplated. However, it is specifically noted herein that the lithium salts of 2,5-diaspartyl-3,6-diketopiperazine and 2,5-diglutamyl-3,6-diketopiperazine are not considered within the scope of the present invention and as such are hereby specifically disclaimed.

The compound of Formula 3 will be referred to hereinafter as 2,5-diglutamyl-3,6-diketopiperazine. It is understood that all other heterocyclic compounds based on Formula 1 are considered within the scope of the present invention.
[0058] For exemplary purposes, diketopiperazines salts and their derivatives will be described in detail. These compounds are the preferred embodiments of the present invention. However, this does not exclude other heterocyclic compounds based on the compound of Formula 1.
[0059] The use of DKP salts for the delivery of phosphodiesterase type 5-inhibitors is described in co-pending U.S. Patent Application No. XX/XXX,XXX filed August 23, 2005 and entitled "Pulmonary Delivery of Inhibitors of Phosphodiesterase Type 5" and known to all by U.S. Provisional Patent Application No. 60/603,764, which is hereby incorporated by reference in its entirety. Pulmonary drug delivery using DKP microparticles is disclosed in U.S. Patent No. 6,428,771 entitled "Method For Drug Delivery To The Pulmonary System", which is hereby incorporated by reference in its entirety.
[0060] Diketopiperazine facilitate transcellular transport of biologically active agents across biological tissues however they are not penetration enhancers.
Penetration enhancers are compounds that improve drug movement across biological tissues by disrupting cell membranes. Examples of penetration enhancers are surfactants and soaps.
Diketopiperazines do not disrupt cell membranes either in vitro or in vivo. In vitro studies demonstrate that FDKP does not disrupt cell membranes or tight junctions and does not compromise cell viability. Diketopiperazine/insulin powder compositions are soluble at the physiological pH of the lung surface and dissolve rapidly after inhalation.
Once dissolved, the DKP facilitates passive transcellular transport of the insulin.
[0061] Applicants have discovered improved diketopiperazine compositions having greater solubility at a neutral and/or acidic pH. Applicants have also discovered that therapeutic complexes between improved diketopiperazines and drug(s) of interest can be formed.
[0062] The salts of the present invention can be prepared by reacting the diketopiperazine free acid with a solution of an appropriate base as described in Examples 1 and 2 below. In a preferred embodiment, the salt is a pharmaceutically acceptable salt such as the sodium (Na), potassium (K), lithium (Li), magnesium (Mg), calcium (Ca), ammonium, or mono-, di- or tri-alkylammonium (as derived from triethylamine, butylamine, diethanolamine, triethanolamine, or pyridines, and the like) salts of diketopiperazine, for example. The salt may be a mono-, di-, or mixed salt. Higher order salts are also contemplated for diketopiperazines in which the R groups contain more than one acid group.
In other aspects of the invention, a basic form of the agent may be mixed with the DKP in order to form a drug salt of the DKP, such that the drug is the counter cation of the DKP.
[0063] For drug delivery, biologically active agents or drugs having therapeutic, prophylactic, or diagnostic activities can be delivered using diketopiperazines. Essentially, the biologically active agent is associated with the diketopiperazine particles of the present invention. As used herein, "associated" means a biologically active agent-diketopiperazine composition formed by, among other methods, co-precipitation, spray drying or binding (complexation) of the diketopiperazine with the biologically active agent. The resulting diketopiperazine particles include those that have entrapped, encapsulated and/or been coated with the biologically active agent. While the exact mechanism of association has not been conclusively identified, it is believed that the association is a function of physical entrapment (molecular entanglement) in addition to electrostatic attraction including hydrogen bonding, van der Waal's forces and adsorption.
[0064] The biologically active agents that can be associated with the diketopiperazine particles of the present invention include, but are not limited to, organic or inorganic compounds, proteins, or a wide variety of other compounds, including nutritional agents such as vitamins, minerals, amino acids, carbohydrates, sugars, and fats. In preferred embodiments, the drugs include biologically active agents that are to be released in the circulatory system after transport from the GI tract following oral delivery.
In other preferred embodiments the materials are biologically active agents that are to be released in the circulatory system following pulmonary or nasal delivery. In other preferred embodiments the materials are biologically active agents that are to be release in the central nervous system following nasal delivery. Additionally, the drug can be absorbed through mucosal tissue such as rectal, vaginal, and/or buccal tissue. Non-limiting examples of biologically active agents include proteins and peptides (wherein protein is defined as consisting of 100 amino acid residues or more and a peptide is less than 100 amino acid residues), such as insulin and other hormones, polysaccharides, such as heparin, nucleic acids (such as plasmids, oligonucleotides, antisense, or siRNA), lipids and Iipopolysaccharides, and organic molecules having biological activity such as many of the antibiotics, anti-inflammatories, vasoactive agents (including agents used to treat erectile dysfunction) and neuroactive agents. Specific non-limiting examples include steroids, hormones, decongestants, anticoagulants, immunomodulating agents, cytotoxic agents, antibiotics, antivirals, anesthetics, sedatives, antidepressants, cannabinoids, anticoagulants, antisense agents, antigens, and antibodies. In some instances, the proteins may be antibodies or antigens which otherwise would have to be administered by injection to elicit an appropriate response.
More particularly, compounds that can be associated with the diketopiperazine compositions of the present invention include insulin, heparins, calcitonin, felbamate, parathyroid hormone and fragments thereof, growth hormone, erythropoietin, glucagon-like peptide-1, somatotrophin-releasing hormone, follicle stimulating hormone, cromolyn, adiponectin, RNAse, ghrelin, zidovudine, didanosine, tetrahydrocannabinol (i.e., cannabinoids), atropine, granulocytes colony stimulating factor, lamotrigine, chorionic gonadotropin releasing factor, luteinizing releasing hormone, beta-galactosidase and Argatroban. Compounds with a wide range of molecular weight can be associated, for example, between 100 and 500,000 grams per mole.
[0065] Imaging agents including metals, radioactive isotopes, radiopaque agents, and radiolucent agents, can also be incorporated into diketopiperazine delivery systems.
Radioisotopes and radiopaque agents include gallium, technetium, indium, strontium, iodine, barium, and phosphorus.
[0066] Additionally the drugs can be in various forms, such as uncharged molecules, metal or organic salts, or prodrugs. For acidic drugs, metal salts, amines or organic cations (e.g., quaternary ammonium) can in some cases be used.
[0067] In some embodiment, the drugs include biologically active agents that are to be released in the circulatory system after transport from the gastrointestinal tract following oral delivery. In other embodiments, the biologically active agents are to be released in the circulatory system following pulmonary or nasal delivery. In still other embodiments, the biologically active agents are to be released in the central nervous system following nasal delivery. Additional, the drugs can be absorbed through mucosal tissue such as rectal, vaginal, and/or buccal tissue.
[0068] Some of these biological agents are unstable in gastric acid, diffuse slowly through gastrointestinal membranes, are poorly soluble at physiological pH, and/or are susceptible to enzymatic destruction in the gastrointestinal tract. The biological agents are combined with the diketopiperazine salts to protect them in the gastrointestinal tract prior to release in the blood stream. In a preferred embodiment the diketopiperazines are not biologically active and do not alter the pharmacologic properties of the therapeutic agents.
[0069] To associate one or more drugs with a DKP salt, the drug and the DKP
salt are preferably mixed in solution or suspension and subsequently dried. Either component may be present as solute or suspendate. In different embodiments the mixture is spray dried or lyophilized.
[0070] Spray drying is a thermal processing method used to form, load or dry particulate solids from a variety of solutions or suspensions. The use of spray drying for the formation of dry particulate pharmaceuticals is known in the art however in the past its use had been limited by its incompatibility with biological macromolecular drugs, including protein, peptides and nucleic acids due to the nature of the spray drying process. During spray drying, a solution or suspension is formed into droplets through aerosolization and, then passed through a heated gas stream having sufficient heat energy to evaporate water and solvents in the particles to a desired level before the particles are collected. The inlet temperature is the temperature of the gas stream leaving its source and its level is selected based upon the lability of the macromolecule being treated. The outlet temperature is a function of the inlet temperature, the heat load required to dry the product along with other factors.
[0071] The present inventors have unexpectedly determined that the particles of the present invention, have aerodynamic performance which improves with increasing content of a biologically active agent which has not been seen with other particles. The respirable fraction (%rf), the percentage of particles between 0.5 and 5.8 microns in diameter, of the spray dried particles of the present invention increases with increasing insulin content, rather than decreasing as was expected. Therefore using the methods of the present invention, diketopiperazine microparticies can be formed which have higher biologically active agent content that was previously achievable.
[0072] Additionally, the present inventors have surprisingly determined that spray dried FDKP disodium salt/insulin compositions have increased insulin stability as the concentration of the FDKP disodium salt in the starting solution increases.
Stability was measured by insulin loss after 17 days at 40 C/75 /a relative humidity. For example, 8.5%
insulin was lost from powder spray dried from a solution containing 37 mg/mL
solids (total weight of FDKP disodium salt/insulin). By comparison, 4.5% insulin was lost from powder spray dried from a solution containing 45 mg/mL solids and 2.7% insulin was lost from powder spray dried from a solution containing 67 mg/mL solids.
[0073] In a further observation, inlet temperature was found to have surprising effects on insulin stability. The data indicate that insulin stability in the powder increases with increasing inlet temperature as measured by insulin loss after 17 days at 40 /75% RH. For example, about 4% insulin was lost from powder spray dried at an inlet temperature of 180 C. By comparison, <1% insulin was lost from powder spray dried at an inlet temperature of 200 C.
[0074] In an embodiment of the present invention, microparticles suitable for delivery to the pulmonary system are provided wherein the microparticles have a rugosity of less than 2. Another aspect of the present invention influenced by spray drying is the particle morphology, measured by rugosity, which the ratio of the specific area and the surface area calculated from the particle size distribution and particle density. The drying operation may be controlled to provide dried particles having particular characteristics, such as rugosity.
Rugosity of spray dried particles is a measure of the morphology of the surface of the particles, such as the degree of folding or convolution.
[0075] It had previously been thought that a rugosity above 2 was needed in order to obtain particles with sufficient dispersability to form a free-flowing powder.
Surprisingly, the present inventors have produced particles suitable for pulmonary delivery with a rugosity below 2 [0076] The microparticle formulations of the present invention can be administered as a liquid or solid form. These can include solutions, suspensions, dry powders, tablets, capsules, suppositories, patches for transdermal delivery, and the like. These different forms offer distinct, but overlapping, advantages. The solid forms provide convenient bulk transport of drugs and can improve their stability. They can also be formed into microparticles enabling administration by inhalation specifically to the nasal mucosa or deep lung, depending on the size of the microparticle. Diketopiperazines can also facilitate absorption of the associated drug even when delivered as a solution. Some of the DKP salts (for example, the sodium and potassium salts) offer improved solubility at neutral and acidic pH as compared to the free acid, which can lead to improved absorption in the stomach of orally administered solid forms.
[0077] Dikeopiperazine salt counter cations may be selected to produce salts having varying solubilities. These varying solubilities can be the result of differences in dissolution rate and/or intrinsic solubility. By controlling the rate of DKP salt dissolution, the rate of drug absorption from the DKP salt/drug combination can also be controlled to provide formulations having immediate and/or sustained release profiles. For example, sodium salts of organic compounds are characteristically highly soluble in biological systems, while calcium salts are characteristically only slightly soluble in biological systems. Thus, a formulation comprised of a DKP sodium salt/drug combination would provide immediate drug absorption, while a formulation comprised of a DKP calcium salt/drug combination would provide slower drug absorption. A formulation containing a combination of both of the latter formulations could be used to provide immediate drug absorption followed by a period of sustained absorption.
[0078] Diketopiperazine salt formulations of biologically active agents may be administered orally. Microparticles, depending on the chemical nature and size, are absorbed through the epithelial lining of the gastrointestinal tract into the bloodstream or lymphatic system. Alternatively, the composition can be administered as a solution in which the DKP salt serves to facilitate the absorption of the drug. Additionally, the microparticles can be administered as a suspension or a solid dosage form that dissolves completely and is absorbed following dissolution.
[0079] For parenteral administration, microparticles of less than five microns readily pass through a needle for intravenous administration. Suitable pharmaceutical carriers, for example, phosphate buffered saline, are known and commercially available.
Similarly, microparticles can be injected or implanted subcutaneously, intramuscularly, or intraperitoneally. Additionally, the microparticles can be placed in an implantable device to facilitate sustained and/or controlled delivery.
[0080] For topical or transdermal administration, microparticles can be suspended in a suitable pharmaceutical carrier for administration using methods appropriate for the carrier and site of administration. For example, microparticles are administered to the eye in a buffered saline solution, at a pH of approximately 7.4, or in an ointment such as mineral oil.
The dosage will be dependent on the compound to be released as well as the rate of release. The microparticles, or aggregations of microparticles into films, disks, or tablets, with incorporated compound can be administered to the skin in an ointment, cream, or patch.
Suitable pharmaceutical carriers are known to those skilled in the art and commercially available. Mucosal administration, including buccal, vaginal, rectal, nasal administration is also contemplated.
[0081] Pulmonary delivery can be very effectively accomplished using dry powders comprising the microparticles of the invention and can lead to rapid absorption into the circulation (bloodstream). Dry powder inhalers are known in the art and particularly suitable inhaler systems are described in U.S. patent application nos. 09/621,092 and 10/655,153, both entitled "Unit Dose Capsules and Dry Powder Inhaler", which are hereby incorporated by reference in their entirety. Information on pulmonary delivery using microparticles comprising diketopiperazine can be found in U.S. Patent No. 6,428,771 entitled "Method for Drug Delivery to the Pulmonary System," which is hereby incorporated by reference in its entirety. The following examples are meant to illustrate one or more embodiments of the invention and are not meant to limit the invention to that which is described below.

The material was suspended in 75 mL of deionized water. Insulin (0.84 g) was added to the FDKP salt suspension. The resulting slurry was titrated to a pH of 8.3 with NH4OH to form a solution. The FDKP disodium salt and insulin solution was brought to a volume of 100 mL with deionized water and filtered through a 0.22 pm polyethersulfone membrane. The solution was spray-dried using a BUCHI Mini Spray Dryer B-191 (Buchi Labortechnik AG, Switzerland) under the following conditions.

beaker with a magnetic stir bar. The material was suspended in 75 mL of deionized water.
Insulin (1.68 g) was added to the FDKP salt suspension. The resulting slurry was titrated to a pH of 8.3 with NH4OH to form a solution. The FDKP disodium salt and insulin solution was brought to a volume of 100 mL with deionized water and filtered through a 0.22 pm polyethersulfone membrane. The solution was spray-dried using a BUCHI Mini Spray Dryer B-191 (Buchi Labortechnik AG, Switzerland) under the following conditions.

Example 8. Characterization of Disodium FDKP-Insulin Microparticles [0089] The microparticles described in Examples 6 and 7 were subjected to laser diffraction particle size analysis (SympatecGmbH, Germany) (FIGs. 1A and 1B).
The particles of Example 6 displayed an average respirable fraction (according to the USP
definition of 0.5 to 5.8 microns) of 87.93% with a standard deviation of 1.60 and a %CV
(coefficient of variation) of 1.82. The particles of Example 7 displayed an average respirable fraction of 81.36% with a standard deviation of 4.20 and a %CV of 5.16.
Example 9. Pulmonary Administration of Disodium FDKP-Insulin [0090] A dry powder containing the disodium FDKP salt and insulin is inhaled at the beginning of meal. The particles that comprise the dry powder are preferably in the range of approximately 0.5 - 5.8 microns in size. The exact dosage is patient-specific, but generally on the order of 5-150 Units of insulin per dose. The insulin absorption from this dosage regimen mimics physiologic first-phase insulin release, and attenuates post-prandial blood glucose excursions.
Example 10. Preparation of an Oral Dosage Form [0091] Spray-dried disodium FDKP/insulin powder as described in Examples 6 or 7 is packed into hard gelatin capsules. The capsules can contain approximately 50-100 mg of powder. The FDKP salt/insulin powders prepared in Examples 6 and 7 were 25%
insulin by weight and insulin activity was about 26 units/mg. Thus, 50 mg would be on the order of 1300 units, significantly larger than a typical dose. About 2-30 mg of the FDKP salt/insulin powder is mixed with methyl cellulose (other bulking agents are well known in the art) to make up the balance of the desired mass.
Example 11. Oral Administration of Disodium FDKP-Insulin [0092] Capsules containing the FDKP salt and insulin are taken before a meal.
The exact dosage is patient-specific, but generally on the order of approximately 10-150 units of insulin is administered per dose. The subsequent insulin absorption attenuates post-prandial blood glucose excursions. This oral insulin formulation is used to replace pre-meal insulin injections in patients with diabetes. Additionally, insulin absorbed through the gastrointestinal tract mimics endogenous insulin secretion. Endogenous insulin is secreted by the pancreas into the portal circulation. Insulin absorbed following oral administration also goes directly to the portal circulation. Thus, the oral route of insulin administration delivers insulin to its site of action in the liver, offering the potential to control glucose levels while limiting systemic exposure to insulin. Oral insulin delivery using a combination of insulin and the diacid form of FDKP is hindered by the poor solubility of the FDKP diacid in the low pH environment of the gastrointestinal tract. The FDKP salts, however, provide a local buffering effect that facilitates their dissolution in low pH.
Example 12. Preparation C of FDKP Di-Sodium Salt [0093] Fifty grams of fumaryl diketopiperazine (FDKP, 221.01 mmol, 1 equiv.), water (200 mL), and 10 N sodium hydroxide (21.9 mL, 437.61 mmol, 1.98 equiv.) were charged to a 1-liter, 4-neck, round bottom flask equipped with a reflux condenser, o.verhead stirrer, nitrogen inlet, and thermometer. The mixture was heated to 50 C to achieve a yellow solution and ethanol (650 mL) was added over 15 minutes. When the addition was complete, the slurry was held at 50 C for 30 - 60 minutes. The reaction mixture was vacuum filtered and the isolated solids were washed with ethanol (150 mL) and acetone (150 mL x 2) then dried in a vacuum oven (50 C, 30 inches of mercury) overnight. No further purification was required. The salt was assayed for moisture content (Karl Fischer) and sodium content (elemental analysis and titration). The yield of the salt was from about 90%
to about 95%.

Example 13: FDKP salt/insulin powder prepared by spray drying [0095] The disodium salt of FDKP (5 g) was dissolved in deionized water (150 mL) and insulin (1.69 g) was added. The pH of the suspension was adjusted to 8.3 with ammonium hydroxide (NH4OH) to give a solution that was subsequently diluted to 200 mL
with deionized water and filtered. The solution was spray dried using the following conditions:
Inlet temperature - 200 C
Outlet temperature - 80 C
Atomization gas - 600 liter N2/hr Process gas - 80% of maximum The spray nozzle was cooled to 28 C
[0096] The resultant particles were analyzed for their aerodynamic properties and the data are reported in Table 3.

[0099] Scanning electron microscopy (SEM) was utilized to study particle morphology.
A representative SEM is shown in Figure 3. The particle morphology is consistent with a collapsed hollow sphere.
[0100] The stability of the disodium salt/insulin particles was evaluated under accelerated room temperature conditions (40 /75% relative humidity [RH]).
Compared to a control formulation prepared by lyophilization, the spray-dried particles demonstrated superior insulin stability as measured by insulin degradation (Figure 4).
[0101] The starting concentration of the FDKP disodium salt/25%insulin solution prior to spray drying was evaluated for its effect on final particle stability. The data (Figure 5) shows that insulin stability on the particle increases with increasing solution concentrations as measured by insulin loss after 17 days at 40 /75% RH.
Example 14. Solvent/anti-solvent precipitation of a solution of FDKP
salt/insulin with an organic solvent [0102] The precipitation was controlled using harmonic ultrasonic atomization.
Alternate cavitation methods as well as high shear mixing and homogenization are also applicable.
[0103] The disodium salt of FDKP (5 g) was dissolved in deionized water (80 mL).
Insulin (0.65 g) was added to the solution to produce a suspension. The pH of the suspension was adjusted to 8.3 with NH4OH to obtain a solution that was diluted to 100 mL
with deionized water and filtered. The particles were precipitated by pumping the insulin/disodium salt of FDKP solution and ethanol in a 1:5 ratio through a duel inlet atomization horn vibrating at a frequency between 20 kHz and 40 kHz. The precipitate was collected in a media bottle containing ethanol (200 mL). Post-precipitation the material was washed with ethanol and dried via rotary evaporation or by bubbling nitrogen through the suspension. The particles contained 12.5% insulin by weight. Particle morphology was evaluated by SEM (Figure 6).
[0104] The particles illustrated in FIG. 6A (10k x) and FIG. 6B (20K x) are in the 1 to 5 micron range while at lower magnification (FIG. 6C, 2.5k x and FIG. 6D, 1.0k x) particles in the 10 to 40 micron range are seen. It is the non-binding hypothesis of the present inventors that the drying methods utilized in this study resulted in recrystalization of the primary particles into much larger secondary particles and that the use of a method that maintains a constant ratio of organic to aqueous components throughout the drying process, such as spray drying, can preserve the primary particles to the exclusion of the formation of a significant number of secondary particles.
Example 15. In situ diammonium salt formation and formulation.
[0105] FDKP or SDKP (succinyl DKP) diammonium salt/insulin particles were formed by spray drying. A representative procedure is given for the FDKP ammonium salt/insulin formulation containing 25% insulin.
[0106] FDKP (5 g) was suspended in deionized water (150 mL) and titrated to a pH of 7.5 to 8.0 with ammonium hydroxide (NH4OH). Insulin (1.69 g) was added to the resulting solution (FDKP) to give a suspension. The pH of the suspension was adjusted to 8.3 with ammonium hydroxide (NH4OH) to give a solution that was diluted to 200 mL with deionized water and filtered. The powder was produced by spray drying the solution under the following conditions.
Inlet temperature - 200 C
Outlet temperature - 80 C
Atomization gas - 600 liter N2/hr Process gas - 80% of maximum The spray nozzle was cooled to 28 C
[0107] The %rf of the diammonium salts is about 10% higher than the %rf of the disodium salt. The counter cation has a large effect on particle performance.
Also, the 50%
FDKP ammonium salt/insulin powder has a %rf comparable to that of the corresponding 25% FDKP ammonium salt/insulin powder. This is surprising because with the powders prepared by lyophilization from the FDKP free acid, the %rf decreases as the insulin content increases.
[0108] The resultant particles were analyzed for their aerodynamic properties and the data are reported in Table 5.

[0110] Particle size of a preparation of the diammonium salt of FDKP

[0112] Particle size for the SDKP diammonium salt formulated with 25% insulin (w:w) was determined by laser diffraction and demonstrated a size range of approximately 1.7pm - 9.3pm for the SDKP diammonium salt formulated with 25% insulin.
[0113] Scanning electron microscopy was utilized to study particle morphology.
Representative SEMs are shown in the Figure 10 (FDKP) and Figure 11 (SDKP).
The particle morphology is consistent with a collapsed hollow sphere.
[0114] The stability of the in situ salt formation and formulation of the diammonium salt/insulin particles was evaluated under accelerated room temperature conditions (40 /75%
RH). Compared to a control formulation prepared by lyophilization, the spray dried particles demonstrated superior insulin stability as measured by insulin degradation (FDKP, Figure 12 and SDKP, Figure 14) and formation of the desamino degradrant (A21) (FDKP, Figure 13 and SDKP, Figure 15).
Example 16. Characteristics of Spray Dried Microparticles.
[0115] Spray dried FDKP salt/insulin particles demonstrate a surprising and unexpected trend in aerodynamic performance. Previously observed insulin-containing microparticles, which had been formed from DKP free acid microparticles onto which insulin had been loaded and the solvent removed by lyophilization, demonstrated decreased aerodynamic performance with increasing insulin content. For example, the %rf (respirable fraction) for 25% loaded particles was significantly lower than the %rf for 5%
loaded particles. For spray dried FDKP salt microparticles containing insulin, the opposite trend is observed. As insulin load increases, %rf increases.
[0116] Spray dried powders of the FDKP disodium salt were prepared with insulin contents of 11.4%, 50.0%, 70.0%, or 90.0% (w:w). Figure 16 shows that %rf increases with increasing insulin load.
[0117] A similar trend was also observed in spray dried FDKP diammonium salt/insulin powders having insulin contents of 11.4%, 50.0%, 70.0%, or 90.0% (w:w). The %rf increased with insulin load (Figure 17).
[0118] The starting concentration of the FDKP disodium salt solution prior to spray drying was evaluated for its effect on final particle insulin stability. The data indicate that insulin stability in the powder increases with increasing solution concentrations as measured by insulin loss after 17 days at 40 /75% RH. For example, 8.5% insulin was lost from powder spray dried from a solution containing 37 mg/mL solids. By comparison, 4.5%
insulin was lost from powder spray dried from a solution containing 45 mg/mL
solids and 2.7% insulin was lost from powder spray dried from a solution containing 67 mg/mL solids.
[0119] The inlet temperatures used to spray dry solutions of the FDKP disodium salt and insulin to form particles containing 50% insulin was evaluated for its effect on final particle insulin stability. The data indicate that insulin stability in the powder increases with increasing inlet temperature as measured by insulin loss after 17 days at 40 /75% RH. For example, about 4% insulin was lost from powder spray dried at an inlet temperature of 180 C. By comparison, <1% insulin was lost from powder spray dried at an inlet temperature of 200 C.
[0120] Additionally, the present inventors have unexpected found that these particles, which are suitable for pulmonary delivery, have a rugosity of approximately 1.
