A migraine is a moderate to severe headache on one side of the head. A migraine attack is a headache that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. A number of treatments are available for adults with migraine but there are limited approved treatments available for participants less than 18 years of age. The main goal of the study is to evaluate the long-term safety and tolerability of atogepant in pediatric participants between the ages of 6 and 17 with migraine. Atogepant is a medicine currently approved to treat adults with migraine (0 to 14 migraine days per month) and is being studied in pediatric participants between the ages of 6 and 17 with a history of migraine. This is a Phase 3, open-label study of atogepant in participants with a history of migraine. Participants must have completed participation in another study of atogepant (lead-in study). Participants must have 4 to 14 migraine days and less than 15 headache days for episodic migraine, and \>= 15 headache days and \>= 8 migraine days for chronic migraine in the 4-week screening electronic diary (eDiary; similar to a smart phone). Around 650 participants will be enrolled in the study at approximately 100 sites worldwide. Atogepant is a tablet taken once a day by mouth. Participants between the ages of 12 and 17 will receive high dose atogepant for 52 Weeks. Participants between the ages of 6 and 11 will receive an atogepant dose determined in the lead-in study for 52 Weeks. There may be a bigger responsibility for participants in this study. Participants will attend regular visits during the study at a hospital or clinic. The effects of treatment will be checked by medical assessments, blood tests, checking for side effects, and completing questionnaires.

Percentage of Participants with Adverse Events (AEs)
AE, defined as any unfavorable medical event that is temporarily related to the use of the investigational product, which does not necessarily have a causal relationship with the investigational product.
Time frame: Up to 56 Weeks
Percentage of Participants with Potentially Clinically Significant Lab Values
Percentage of participants with abnormal change in clinical laboratory test results like hematology, chemistry and urinalysis will be assessed.
Time frame: Up to 52 Weeks
Percentage of Participants with Potentially Clinically Significant Clinical 12-lead Electrocardiogram (ECG)
12-lead resting ECGs will be recorded. Parameters include heart rate, PR interval, QT interval, QRS duration, and QT interval corrected using Fridericia's formula (QTcF).
Time frame: Up to 52 Weeks
Percentage of Participants with Potentially Clinically Significant Vital Sign Parameters
Number of participants with abnormal change from baseline in vital sign measurements like systolic and diastolic blood pressure will be assessed.
Time frame: Up to 52 Weeks
Percentage of with Participants with Treatment-Emergent Suicidal Ideations with Intent, with or without a Plan (i.e., Type 4 or 5 on Columbia-Suicide Severity Rating Scale [C-SSRS]), or any Suicidal Behaviors
The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and behavior. Suicidal ideation was 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).
Time frame: Up to 52 Weeks
Percentage of Participants with Change in Menstrual Cycle (Female Participants Only)
Female participants who have entered menarche are to be asked for the date of the first and last day of their most recent menstrual period.
Time frame: Up to 52 Weeks
Change from Baseline in Tanner Staging Score
Tanner's staging is used to assess growth and pubertal development.
Time frame: Baseline (Week 0) through Week 52
Change from Baseline in Behavior Rating Inventory of Executive Function, 2nd Edition (BRIEF 2) questionnaire
The BRIEF 2 is an 86-item questionnaire assessing executive function. It consists of 2 indexes, Behavioral Regulation and Metacognition, which are then used to calculate an overall composite score. Higher scores indicate more executive difficulties
Time frame: Baseline (Week 0) through Week 52
