Study Evaluating the Efficacy, Safety, and Tolerability of ASY202 (Dihydroergotamine Mesylate [DHE] Inhalation Powder Delivered Via a Multidose Dry Powder Inhaler) for the Acute Treatment of Migraine in Adult Patients

This study is testing an investigational inhaled migraine medication to see how well it works, how safe it is, and how well people tolerate it. Adults with migraine will receive both the study medication (ASY202) and a placebo (inactive treatment) at different times during the study. Neither participants nor study staff will know which treatment is given at the time. The medication is taken using a handheld dry powder inhaler to treat migraine attacks when they occur.

Following screening, eligible participants will be enrolled and randomized to one of two treatments sequences i.e. one treatment sequence will receive ASY202 in treatment period 1 followed by placebo in treatment period 2 and other treatment sequence will receive placebo in treatment period 1 followed by ASY202 in treatment period 2.

The study lasts about 16 weeks and includes a screening period, two treatment periods (with a minimum of 7 days washout period between the treatment periods), and a safety follow-up visit.

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Able to understand study procedures and provide written informed consent
  • Male or female, 18-65 years of age at Screening
  • BMI between 18.5-35 kg/m² at Screening
  • Documented history of migraine (with or without aura) for ≥1 year, consistent with the International Classification of Headache Disorders, 3rd Edition (ICHD-3)
  • Female participants must be either:
  • of non-childbearing potential, or
  • of childbearing potential using protocol required contraception

Exclusion criteria

  • Diagnosis of headache conditions other than migraine
  • History or current diagnosis of coronary artery disease (CAD)
  • History or current diagnosis of coronary artery vasospasm (including Printz-metal's angina), clinically significant arrhythmia (e.g., ventricular tachycardia, ventricular fibrillation) or peripheral vascular disease, ischemic disease (e.g., Raynaud's syndrome, ischemic bowel syndrome, angina pectoris, myocardial infarction, or documented silent ischemia)
  • History of percutaneous coronary intervention, cardiac surgery, sepsis or vascular surgery
  • History or current diagnosis of cerebrovascular disease, including but not limited to stroke, transient ischemic attack, cerebral hemorrhage, or subarachnoid hemorrhage
  • Known history or current diagnosis of psychological and/or psychiatric condition that, in the opinion of the Investigator, might interfere with study participation and assessments or participant safety. These conditions may include depression, psychosis, schizophrenia, bipolar disorder, dementia, alcoholism, drug abuse, etc.
  • Known allergic reactions, hypersensitivity, or contraindications to DHE, other ergot-derived products, or any other excipient in the formulation
  • Use of strong or moderate CYP3A4 inhibitors within 14 days (or 5 half-lives) or CYP3A4 inducers within 28 days (or 5 half-lives) prior to Randomization
  • Any clinically significant symptoms or conditions at screening, other than migraine, including but not limited to central nervous system (e.g., seizures), cardiac, pulmonary, metabolic, renal, hepatic, or gastrointestinal conditions, or history of such conditions that in the opinion of the Investigator, might interfere with study assessments or participant safety

Treatment and study plan

ASY202

Combination Product

ASY202 is a pre-metered drug-device combination product containing a dry-powder formulation of dihydroergotamine (DHE) intended for oral inhalation, delivered via a dry powder inhaler (DPI).

Placebo

Combination Product

Placebo inhalation powder delivered via a dry powder inhaler (DPI) device.

Primary outcomes

  1. Proportion of patients with freedom from headache pain at 2 hours post-dose

    Time frame: 2 hours Post-Dose

    Proportion of patients achieving freedom from headache pain at 2 hours following administration of a single 2.0 mg dose of ASY202 compared with placebo. Headache pain freedom is defined as a reduction from moderate or severe headache intensity (score of 2 or 3 on a 4-point scale) at baseline (time 0) to no headache pain (score of 0 on the same 4-point scale) at 2 hours post-dose.

Secondary outcomes

  1. Proportion of patients with freedom from the most bothersome symptom (MBS) at 2 hours post-dose.

    Time frame: 2 hours Post-Dose

    Proportion of patients achieving freedom from their most bothersome symptom (MBS), among photophobia, phonophobia, and nausea/vomiting, at 2 hours following administration of a single 2.0 mg dose of ASY202 compared with placebo. Freedom from the MBS is defined as the absence of the MBS at 2 hours post-dose if present at baseline (time 0).

  2. Proportion of patients with relief from headache pain at 2 hours post-dose

    Time frame: 2 hours Post-Dose

    Proportion of patients achieving headache pain relief at 2 hours following administration of a single 2.0 mg dose of ASY202 compared with placebo. Headache pain relief is defined as a reduction from moderate or severe headache intensity (score of 2 or 3 on a 4-point scale) at baseline (time 0) to mild or no headache pain (score of 1 or 0 on the same scale) at 2 hours post-dose.

  3. Proportion of patients with sustained pain-free status from 2 to 24 hours post-dose

    Time frame: 2 to 24 hours post-dose

    Proportion of patients free from headache pain at 2 hours post-dose and who remain headache pain-free through 24 hours post-dose without the use of rescue medication and without relapse of any headache pain (defined as maintaining a score of 0 on a 4-point scale from 2 to 24 hours)

  4. Proportion of patients with headache pain relief at 10 minutes post-dose

    Time frame: 10 minutes post-dose

    Proportion of patients achieving headache pain relief at 10 minutes following administration of a single 2.0 mg dose of ASY202 compared with placebo. Relief is defined as a reduction from moderate or severe headache pain (score of 2 or 3 on a 4-point scale) at baseline to mild or no headache pain (score of 1 or 0 on the same scale) at 10 minutes post-dose.

  5. Proportion of patients with headache pain relief at 30 minutes post-dose

    Time frame: 30 minutes post-dose

    Proportion of patients achieving headache pain relief at 30 minutes following administration of a single 2.0 mg dose of ASY202 compared with placebo. Relief is defined as a reduction from moderate or severe headache pain (score of 2 or 3 on a 4-point scale) at baseline to mild or no headache pain (score of 1 or 0 on the same scale) at 30 minutes post-dose

  6. Proportion of patients who do not use rescue medication within 24 hours post-dose

    Time frame: 0 to 24 hours post-dose

    Proportion of patients who do not require rescue medication within 24 hours following administration of a single 2.0 mg dose of ASY202 compared with placebo.

  7. Proportion of patients returning to normal functional ability at predefined post-dose timepoints

    Time frame: Up to 48 hours post-dose

    Proportion of patients achieving normal functional ability, defined as a score of 0 on the 4-point Functional Impairment Scale, at prespecified timepoints up to 48 hours following administration of a single 2.0 mg dose of ASY202.

  8. Number of participants with treatment-emergent adverse events

    Time frame: From Screening Visit, through study completion, an average of 16 weeks

    A treatment-emergent adverse event (TEAE) is defined as any adverse event occurring or worsening after administration of study intervention.
