Long-term Safety Study of BHV-3500 (Zavegepant*) for the Acute Treatment of Migraine

Primary Outcome Measures

1. Number Of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and AEs Leading To Discontinuation
   An AE is defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in participants or clinical investigation participants administered an investigational (medicinal) product that does not necessarily have a causal relationship with this treatment. An SAE was defined as any event that met any of the following criteria at any dose: death; life-threatening; inpatient hospitalization or prolongation of existing hospitalization; persistent or significant disability/incapacity; congenital anomaly/birth defect in the offspring of a participant who received study drug; other important medical events that may not have resulted in death, be life-threatening, or required hospitalization, based upon appropriate medical judgment, they may have jeopardized the participant and may have required medical or surgical intervention to prevent one of the other serious outcomes.
2. Number Of Participants With Clinically Significant Laboratory Abnormalities
   Clinically significant laboratory abnormalities were defined as Grades 3 to 4 laboratory test results according to numeric laboratory test criteria found in Common Technical Criteria for Adverse Events Version 5.0 (2017) if available; otherwise, according to Division of Acquired Immune Deficiency Syndrome. Table for Grading the Severity of Adult and Pediatric Adverse Events Corrected Version 2.1 (2017) for glucose, low-density lipoprotein (LDL)-cholesterol, uric acid, and urinalysis. Laboratory test groups of clinical interest included hematology, serum chemistry, and urinalysis. Participants must have had a non-missing measurement in to be included for a given parameter. Laboratory results were presented in US units.
