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
What this study is about
This study is testing an experimental 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.
View original scientific description
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.
Interventions
COMBINATION_PRODUCT
ASY202
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).
COMBINATION_PRODUCT
Placebo
Placebo inhalation powder delivered via a dry powder inhaler (DPI) device.
Primary outcome measures
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.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
