Brief Summary
Migraine is characterized by attacks of throbbing, moderate or severe headache, often associated with nausea, vomiting, and/or sensitivity to light and/or sound. The study will assess safety and tolerability of atogepant when added to BOTOX, as well as prospectively evaluate the efficacy of add-on atogepant for migraine prevention. Adverse events and change in disease activity will be monitored. Atogepant is an investigational drug being developed to prevent chronic migraine. Approximately 75 adult participants will be enrolled at approximately 30 sites in the United States. All participants will receive atogepant oral tablet once a day (QD) during the 24-week treatment period, in addition to their standard of care Botox. 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.

Outcome Measures
Primary Outcomes (5)
Number of Participants With Adverse Events (AEs)
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study drug. 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. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.
From first dose of study drug until 4 weeks following last dose of study drug (up to 28 weeks)
Percentage of Participants With Potentially Clinically Significant (PCS) Laboratory Values (Chemistry, Hematology, Urinalysis) as Assessed by the Investigator
Clinical laboratory test values are considered PCS if they meet either the lower-limit or higher-limit PCS criteria defined in the categories below. The percentage of participants with PCS laboratory values are summarized for hematology, chemistry, and urinalysis. Glomerular Filtration Rate (GFR) is a clinical measurement that calculates how many milliliters of blood the kidneys filter every second. Glucose, Urinalysis: At least 1+ indicates that the urine contains an increased concentration of sugar. Protein, Urinalysis: At least 1+ indicates that the urine contains an increased concentration of protein.
From first dose of study drug until last dose of study drug (24 weeks)
Percentage of Participants With Potentially Clinically Significant (PCS) Vital Sign Measurements as Assessed by the Investigator
Potentially Clinically Significant post-Baseline vital sign values are summarized for categories: systolic and diastolic blood pressures \[sitting\], pulse rate \[sitting\], and weight. Number of participants with non-PCS baseline values who met the PCS criterion at least once post-baseline are reported.
From first dose of study drug until last dose of study drug (24 weeks)
Percentage of Participants With Most Severe Suicidal Ideation and Suicidal Behavior as Assessed by the Columbia-Suicide Severity Rating Scale (C-SSRS) During the Open-Label Treatment Period
The C-SSRS is a clinician-rated instrument that reports the severity of both suicidal ideation and behavior. 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. (Minimum total score 0, maximum total score 5; higher total scores indicate more suicidal ideation and/or suicidal behavior).
From first dose of study drug until last dose of study drug (24 weeks)
Percentage of Participants With Potentially Clinically Significant (PCS) Electrocardiograms (ECGs) Findings as Assessed by the Investigator
12-lead ECGs were performed at select study visits.
From first dose of study drug until last dose of study drug (24 weeks)
Study Arms (1)
Atogepant
EXPERIMENTALParticipants received atogepant 60 mg once a day (QD) during the 24-week treatment period.

Eligibility Criteria
You may qualify if:
- At least a 1-year history of chronic migraine (CM), with or without aura, consistent with a diagnosis according to International Classification of Headache Disorders 3rd edition (ICHD-3 2018) and with or without acute medication overuse as defined in the protocol.
- Must be currently treated with BOTOX for CM: treated with \>= 2 treatment cycles in the 8 months prior to Visit 2 (Day 1) with documentation of payer authorization or written attestation of self-pay to support continued use of BOTOX.
- Must have 8 to 23 (inclusive) migraine days in the electronic diary \[eDiary\] screening/baseline period (eDiary data must have been collected for at least 20 days).
You may not qualify if:
- Use of opioid-containing products for more than 4 days per month for acute treatment of headache in the 3 months prior to Screening or during the screening/baseline period.
- Treatment of study target muscles using acupuncture, transcutaneous electrical nerve stimulation (TENS), cranial traction, dental splints for headache, or head and/or neck injections of anesthetics/steroids within 4 weeks prior to Screening and throughout the study.
- Concurrent use of any migraine prevention treatment other than BOTOX (required concomitant medication; or topiramate \<=100mg daily) including use of oral gepants in the 4 weeks prior to screening nor during the screening/baseline period.
- Current use or use within the 6 months (24 weeks) prior to Screening, of mAbs blocking the CGRP pathway.
- Concurrent use of oral gepants for acute migraine treatment in the 4 weeks prior to screening nor during the screening/baseline period.
