About

Migraine is a common neurological disorder typically characterized by attacks of throbbing, moderate to severe headache, often associated with nausea, vomiting, and sensitivity to light and sound. Migraine is extremely common and disabling in children. The purpose of this study is to evaluate long term safety and tolerability of ubrogepant in the acute treatment of migraine in pediatric participants.

Ubrogepant is a drug approved for the acute treatment of migraine in adults. Pediatric participants (aged 6-17 years) with a history of migraine will be enrolled. Participants who completed the lead-in Study 3110-305-002, as well as those who were placebo responders and screen failed, will be eligible to enroll into this study. Around 1200 participants will be enrolled in the study at approximately 120 sites in the United States.

Participants may receive ubrogepant oral tables to treat up to 8 migraine attacks of any intensity per month. There will be an option to take a second dose of study intervention (identical to initial dose), or rescue medication, starting 2 hours after the initial dose. The study duration will be up to 54 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 safety and tolerability of the treatment will be checked by medical assessments, blood tests, checking for adverse events and completing questionnaires.

Enrollment: 1,200 estimated patients

Sex: All

Ages: 6 to 17 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Completers of the lead-in Study 3110-305-002 (in the main study or PK cohort) or those who screen failed due to being placebo responders.
• Demonstrated an acceptable degree of compliance with study procedures in the lead-in study and who, in the investigator's clinical judgment, did not experience an AE that may indicate an unacceptable safety risk for this study.

Exclusion criteria

• Requirement for any medication (eg, barbiturates) or diet (eg, grapefruit juice) that is on the list of prohibited concomitant medications that cannot be discontinued or switched to an allowable, alternative medication at Visit 1.
• An ECG with clinically significant abnormalities at Visit 1 as determined by the investigator.
• Clinically significant abnormalities in physical examination at Visit 1, as determined by the investigator.
• Significant risk of self-harm, based on clinical interview and responses on the C-SSRS, or of harm to others in the opinion of the investigator; participants should be excluded if they report suicidal ideation with intent, with or without a plan (ie, Type 4 or 5 on the C-SSRS), or report suicidal behavior at Visit 1
• Any medical or other reason (eg, unlikely to adhere to the study procedures, keep appointments, or is planning to relocate during the study) that, in the investigator's opinion, might indicate that the participant is unsuitable for the study.
