To determine the safety and tolerability of single doses of inhaled PUR3100 in healthy through the review of AEs
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the maximum drug concentration in blood plasma. This will also be compared to Cmax of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the last observed quantifiable concentration of PUR 3100 in blood plasma. This will also be compared to Clast of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the time time it takes for a drug to reach the maximum concentration (Cmax). This will also be compared to Tmax of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the time time it takes for a drug to reach the last measurable concentration of PUR 3100 in blood plasma. This will also be compared to Tlast of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the drug concentration in blood plasma over time. This will also be compared to the AUC (0-t), AUC (0-inf), and AUC (0-2h) of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects by measuring the time it takes for the amount of drug in the blood to reduce by 50%. This will also be compared to the half life of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects. This will also be compared to the CL/F of participants who receive IV D.H.E. 45.
To characterize the systemic pharmacokinetics (PK) of single doses of inhaled PUR3100 in healthy adult subjects. This will also be compared to the Vz/F of participants who receive IV D.H.E. 45.

| PUR3100 | DRUG | PUR3100 is an inhalation powder containing DHE, an anti-migraine treatment with broad spectrum agonist activity against 5-hydroxytryptamine (5-HT), dopamine, and adrenergic receptors. PUR3100 is provided as 500 µg dose strength capsules. Each capsule contains the drug substance, DHE mesylate, with mannitol, leucine, and sodium chloride as excipients. |
| Dihydroergotamine (D.H.E 45) | DRUG | D.H.E. 45 is ergotamine hydrogenated in the 9, 10 position as the mesylate salt. It is supplied as a clear, colorless solution supplied in sterile ampules for IV, intramuscular, or subcutaneous administration containing (per mL) DHE mesylate, USP 1 mg, ethanol, 94% w/w. 6.2% by volume, glycerin 15% by weight, and water for injection. |
| Matching Placebo for PUR3100 | OTHER | Each capsule of matching placebo is filled with iSPERSE powder comprised of mannitol, leucine, and sodium chloride. The PUR3100 inhalation powder is administered using the supplied RS01 inhalation device (RS01 UHR2, Plastiape S.p.A.). |
| Matching Placebo for D.H.E 45 | OTHER | The matching placebo for D.H.E. 45 is 0.9% sterile saline for injection. |
