Study to Assess the Real-World Effectiveness of Ubrogepant in Adult Participants When Treating During the Prodrome Phase of Migraine Attacks
(PHASES)
What this study is about
Migraine is a neurological disease characterized by moderate or severe headaches, associated with nausea, vomiting, and/or sensitivity to light and sound. This study will assess changes in migraine attack severity for adult participants treating with taken by mouth ubrogepant across migraine attacks. Ubrogepant is a drug that is approved for the acute treatment of migraine in adults.
View original scientific description
Migraine is a neurological disease characterized by moderate or severe headaches, associated with nausea, vomiting, and/or sensitivity to light and sound. This study will assess changes in migraine attack severity for adult participants treating with oral ubrogepant across migraine attacks. Ubrogepant is a drug that is approved for the acute treatment of migraine in adults. Approximately 189 participants will be enrolled in approximately 15 sites across the US. Participants will receive ubrogepant as prescribed by their physician according to their routine clinical practice and local label. Participants will be followed for up to 13 weeks. There is expected to be no additional burden for participants in this trial. Participants will attend regular visits during the study at a hospital or clinic according to their routine clinical practice.

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.
