Brief summary

Migraine is a neurological disease characterized by moderate or severe headache, associated with nausea, vomiting, and/or sensitivity to light and sound. This study will assess the safety and efficacy of the combination use of ubrogepant for the acute treatment of migraine headache in participants taking atogepant once daily for preventive treatment of migraine. Ubrogepant is an approved drug for the acute treatment of migraine. Atogepant is an approved drug for the preventive treatment of migraine. Approximately 235 adult participants with EM will be enrolled in approximately 45 sites in the United States. Participants will receive oral atogepant tablets once daily (QD) for 12 weeks followed by continued atogepant treatment with ubrogepant tablets taken as needed for the next 12 weeks. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

MeasureTime frameDescription
Number of Participants With Adverse Events (AEs)From first dose of study drug until 30 days following last dose of study drug (up to approximately 28 weeks)An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An AE can therefore be any unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. A treatment-emergent adverse event (TEAE) is an AE that occurs or worsens after receiving investigational study drug.
Percentage of Participants With Potentially Clinically Significant (PCS) Laboratory Values as Assessed by the InvestigatorUp to approximately 28 weeksClinical laboratory test values are considered PCS if they meet either the lower-limit or higher-limit PCS criteria defined in the categories below. Percentage of participants with PCS laboratory values are summarized for chemistry, hematology, and urinalysis. Only those categories where at least 1 person had a non-PCS value at Baseline and met the PCS criterion at least once during post-baseline are reported.
Percentage of Participants With Potentially Clinically Significant (PCS) Electrocardiograms (ECGs) Findings as Assessed by the InvestigatorUp to approximately 24 weeks12-lead ECGs were performed at select study visits.

Suicidal ideation is classified on a 5-item scale: 1 (wish to be dead), 2 (nonspecific active suicidal thoughts), 3 (active suicidal ideation with any methods \[not plan\] without intent to act), 4 (active suicidal ideation with some intent to act, without specific plan), and 5 (active suicidal ideation with specific plan and intent). Suicidal behavior is classified on a 5-item scale: 0 (no suicidal behavior), 1 (preparatory acts or behavior), 2 (aborted attempt), 3 (interrupted attempt), and 4 (actual attempt). More than 1 classification can be selected provided they represent separate episodes. Suicidal ideation: Minimum total score 1, maximum total score 5; higher total scores indicate more suicidal ideation. Suicidal behavior: Minimum total score 0, maximum total score 4; higher total scores indicate more suicidal behavior.

Pre-assignment details

A total of 263 participants were enrolled and included in the intent-to-treat (ITT) population; 1 participant withdrew consent before receiving study drug and therefore was not included in the demographics or any analyses.

Population: Safety Population 1 (all subjects who received ≥ 1 dose of study drug during the open-label atogepant treatment period) and Safety Population 2 (all subjects who received ≥ 1 dose of study drug during the open-label atogepant + ubrogepant concomitant-use treatment period).
