A Phase I Study to Study the PK and Safety of Single Doses of STS101, DHE Injection and Nasal Spray in Healthy Subjects

A Randomized, Open-Label, Crossover Study to Evaluate the PK, Bioavailability, Dose Proportionality, Safety, and Tolerability of Single Doses of STS101, DHE Mesylate IM Injection and DHE Mesylate Nasal Spray in Healthy Adult Subjects

Single-center, single-dose, open-label, 2-part, 3-period crossover (in each part), pharmacokinetic and safety study.

Phase 1, open-label, 2-part, single-dose pharmacokinetic and safety study of STS101 in healthy subjects. Part 1 was designed to identify a dose level of STS101 for administration in Part 2. Subjects in Part 1 received 3 ascending doses of STS101 in a 3-period crossover manner. During Part 2, subjects received the dose of STS101 selected from Part 1, 1.0 mg DHE mesylate IM injection, and 2 mg DHE mesylate nasal spray in a randomized, 3 period crossover manner.
