Brief Summary
Migraine is a neurological disease characterized by moderate or severe headache, associated with nausea, vomiting, and/or sensitivity to light and sound (International Classification of Headache Disorders, 2018). Migraine can be further categorized according to the frequency of attacks as episodic migraine (EM) or chronic migraine (CM). This study will assess the effects of BOTOX in preventing migraine in adult participants with EM. BOTOX is being developed for the prevention of migraine in adults with episodic migraine (EM). Participants will be enrolled in 3 different treatment groups. There is 1 in 3 chance that participants will be assigned to receive placebo. Approximately 777 adult participants with EM will be enrolled in approximately 125 sites across the world. Participants will receive intramuscular injections (injected into the muscle) of BOTOX or Placebo on Day 1 and Week 12. Eligible participants will receive BOTOX on Week 24 and Week 36. 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 (2)
Change From Baseline in the Frequency of Monthly Migraine Days Across Months 5 and 6
The frequency of monthly migraine days across Months 5 and 6 is calculated by taking the 2-month average of monthly migraine days over Months 5 and 6. Month 5 and Month 6 are the 28-day daily diary periods ending with Days 56 and Days 84 after the second study treatment intervention day with BOTOX or placebo injections, respectively. Negative changes from Baseline indicate improvement.
Baseline, Months 5-6
Number of Participants With Treatment-Emergent 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.
Double-Blind Phase (Week 0-24); Open-Label Phase (Week 24-48)
