Groups and Cohorts

Group/ CohortIntervention/ Treatment
  • STS101
    • STS101 (dihydroergotamine nasal powder)
  • Drug: Dihydroergotamine
    • Dihydroergotamine is a semi-synthetic derivative of ergotamine tartrate.

Outcome Measures

Primary Outcome Measures

  1. Percentage of Participants With Attacks With Sustained Freedom From Headache Pain 2-48 Hours (Modified Intent to Treat Population) [At Month 12 of Study Medication Dosing]
    The subject's rating was documented on a four-point scale from no pain (= 0), mild pain (= 1), moderate pain (= 2) to severe pain (= 3). Pain freedom means the pain went from moderate (2) or severe (3) to no pain (0).
  2. Percentage of Participants With Attacks With Sustained Freedom From Most Bothersome Symptom 2-48 Hours (Modified Intent to Treat Population) [At Month 12 of Study Drug Administration]
    Subjects were prompted to document the presence of 3 symptoms (photophobia, phonophobia, and nausea) immediately before study drug administration and during the treated migraine attack.
