Methods of Measurements

Particle size for each active agent, excipient, and powder preparation was determined under a dry powder dispersion condition by a laser diffraction system (Mastersizer 2000, Malvern Instruments Ltd.).

Example 2: Pharmacokinetic Study of Intranasal Dihydroergotamine Compositions in Primates

The study described herein is designed to assess the pharmacokinetics of plasma dihydroergotamine (DHE) after intranasal administration using DHE powder compositions described herein, and to compare the pharmacokinetic profiles achieved via intranasal administration of such compositions with those of comparative DHE compositions administered via various dosing routes. The study utilizes Cynomolgus monkeys (Macaca fascicularis, purpose bred) because the nasal cavity of such monkeys is morphologically similar to that in humans, and is commonly used as an experimental animal.

Methods

Animals. Six male Cynomolgus monkeys (Macaca fascicularis, purpose bred), 4 to 6 years old are used, following accredited animal welfare standards.

Test Powder Compositions are listed in Table 2. Each DHE preparation was administered intramuscularly or intranasally to cynomolgus monkeys (3 to 6 kg). Bloods were collected chronologically into tube containing heparin sodium after dosing. DHE concentrations in plasma samples were determined using a LC-MS/MS (Triple Quad 6500 or API 4000, AB SCIEX).

The dose levels of the DHE powder compositions were set at 0.5 or 0.6 mg/body. As comparisons, the doses of the comparative compositions included ones set at 0.1 mg/body for IM injection and 0.6 mg/body for intranasal administration.

Powder DHE compositions were administered intranasally using a Fit-lizer dispenser as noted above, and administration was confirmed by use of a breath monitoring device.

Intranasal solutions were administered using a device manually actuated to deliver substance, and administration was confirmed by use of a breath monitoring device while holding the other nostril closed.

Intramuscular injections were performed into the brachial muscle using a disposable needle and syringe.

Sampling. Blood sampling for pharmacokinetic analyses was performed each dosing day. The sampling points were as follows: Before dosing, 2, 5, 10, 15, 20, 30, 60, 180 minutes after dosing (total: 9 points). Blood was drawn from the femoral vein with a syringe containing heparin sodium. The blood was immediately cooled on ice, centrifuged (4° C., 1710 cg, 3000 rpm, 15 minutes), and the plasma was stored in a deep freezer (−70° C. or below).

Pharmacokinetic Analysis. An LC/MS/MS analytical method was utilized for determination of DHE concentrations in plasma samples. C_max, T_maxand AUC_0-tparameters were measured. Some of the results are summarized in Table 3 and Table 4 below and illustrated in FIGS. 1A to 1F and FIGS. 2A to 2B.

Example 3: X-Ray Powder Diffraction (XYPD) Analysis

For non-treated DHE mesylate, spray-dried DHE/MCC mixture and spray-dried DHE/MCC/HPMC mixture, their XRPD were performed using a Brucker D2 Phaser X-ray diffractometer to evaluate the crystallinity of DHE. FIGS. 3A to 3C contain X-ray diffraction spectra overlay comparing several DHE preparations that comprise DHE alone or with MCC or MCC/HPMC.

Example 4: Scanning Electron Microscope (SEM) Analysis

SEM samples were prepared by dispersing powder onto an adhesive carbon-coated sample stub a coating with a thin conductive layer of gold/palladium using a Polaron Autocoater E5200. Samples were analyzed using a FEI Quanta 200 SEM fitted with an Everhart-Thornley (secondary electron) detector, operating in high vacuum mode. FIG. 4 is a group of scanning electron microscope (SEM) scans of several DHE preparations that comprise DHE alone or with MCC, MCC/HPMC, or PVP.

Formulation A

The study described herein is designed to assess the pharmacokinetics of plasma indomethacin after intranasal administration using indomethacin powder compositions described herein, and to compare the pharmacokinetic profiles achieved via intranasal administration of such compositions with the comparative indomethacin composition administered intranasally. The study utilizes Cynomolgus monkeys (Macaca fascicularis, purpose bred) because the nasal cavity of such monkeys is morphologically similar to that in humans, and is commonly used as an experimental animal.

Four male Cynomolgus monkeys (Macaca fascicularis, purpose bred), 5 to 8 years old are used, following accredited animal welfare standards.

Test Powder Compositions are listed in Table 5. Each intranasal indomethacin composition was administered intranasally to cynomolgus monkeys (5 to 6 kg). Bloods were collected chronologically into tube containing heparin sodium after dosing. Indomethacin concentrations in plasma samples were determined using a LC-MS/MS (LC system: Shimadzu 30A, Shimadzu Corporation; MS/MS system: API4000, AB SCIEX). The dose level of the indomethacin powder compositions was set at 1.0 mg/body.

Intranasal indomethacin compositions were administered intranasally using a Fit-lizer dispenser as noted above, and administration was confirmed by use of a breath monitoring device.

Sampling. Blood sampling for pharmacokinetic analyses was performed each dosing day. The sampling points were as follows: Before dosing, 10, 30, 60, 120 and 240 minutes after dosing (total: 6 points). Blood was drawn from the femoral vein with a syringe containing heparin sodium. The blood was immediately cooled on ice, centrifuged (4° C., 1710 cg, 3000 rpm, 15 minutes), and the plasma was stored in a deep freezer (−70° C. or below).

Pharmacokinetic Analysis. An LC/MS/MS analytical method was utilized for determination of indomethacin concentrations in plasma samples. C_max, T_maxand AUC0-t parameters were measured. Some of the results are summarized in Table 6 and Table 7 below and illustrated in FIG. 5.

X-Ray Powder Diffraction (XRPD) Analysis

For non-treated indomethacin and freeze-dried indomethacin, their XRPD were performed using a Rigaku Ultima IV (Rigaku Corporation) to evaluate the crystallinity of indomethacin. FIG. 6 contain X-ray diffraction spectra overlay comparing several indomethacin preparations that comprise indomethacin alone.

Particle Size Analysis

For IMC Powder Formulation 1, containing the freeze-dried indomethacin, two types of microcrystalline cellulose (Ceolus® PH-F20JP and Ceolus® PH-301, Asahi Kasei Corporation) and tribasic calcium phosphate (ICL Performance Products LP), their particle size was analyzed by laser-diffraction method using a Mastersizer 2000 (Malvern Instruments Limited). Some of the results are summarized in Table 8. An average particle size (Volume under 50%) of IMC Powder Formulation 1 is 22.1 μm
