Experimental: Inhaled PUR3100 1.5 mg and IV placebo -


Treatment: Drugs: PUR3100
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.

Treatment: Drugs: Dihydroergotamine (D.H.E 45)
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.

Other interventions: Matching Placebo for PUR3100
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.).

Other interventions: Matching Placebo for D.H.E 45

Female subjects who are of childbearing potential and male subjects with female partner(s) of childbearing potential must agree to use an effective contraceptive throughout the study (e.g., oral contraceptives or Norplant®; a reliable double barrier method of birth control [diaphragms with contraceptive jelly; cervical caps with contraceptive jelly; condoms with contraceptive foam]; intrauterine devices; partner with vasectomy; or abstinence) and for at least 90 days after study drug administration. In addition, female subjects must have a negative serum pregnancy test at screening and a negative urine pregnancy test prior to dosing.

2. Post-menopausal (= 12 consecutive months of spontaneous amenorrhea and > 50 years of age)
4. Female subjects must agree not to donate ova/oocytes during the study and for 90 days after the last dose of IMP.
5. Male subject must agree not to donate semen during the study and for 90 days after the last dose of IMP.
6. Subject is able and willing to abstain from alcohol for 48 hours prior to admission to the study unit and throughout the entire study until completion of the Day 7 follow up visit.
7. Subject is willing to participate in the study, comply with the study requirements, and voluntarily provide written informed consent.
8. Subject can read, write, and speak English.
9. Subject is mentally competent to provide informed consent.
10. Subject can perform technically acceptable spirometry at screening.
11. Subject can demonstrate the correct inhalation technique for use of the delivery device and to generate sufficient peak inspiratory flow (PIF) of at least 40 L/min using the In-Check DIAL device at screening.
