  • Subjects with contraindications for use of triptans may be included provided they meet all other study entry criteria

Age and Reproductive Status:

  • Male or female subjects ≥ 18 years
  • Women of childbearing potential (WOCBP) must voluntarily use 1 acceptable methods of contraception to avoid pregnancy and to minimize the risk of pregnancy from signing of informed consent through 28 days after study drug administration.

Myocardial infarction (MI), acute coronary syndrome (ACS), percutaneous coronary intervention (PCI), cardiac surgery, stroke, or transient ischemic attack (TIA) during 6 months prior to screening
  • Poorly controlled hypertension (high blood pressure) or poorly controlled diabetes (but subjects with stable hypertension and/or diabetes for at least 3 months prior to screening may be included in the study). Blood pressure greater than 150 mmHg systolic or 100 mmHg diastolic after 10 minutes of rest is exclusionary

  • Subjects with detectable levels of cocaine, amphetamines, and phencyclidine in drug abuse screening need to be excluded.

Subjects who are positive for amphetamines on the urine drug screen may have their urine samples evaluated for further analysis at the investigator's discretion to rule out a false positive result

  • Subjects with detectable levels of marijuana during substance abuse screening may not be excluded if they do not meet DSMV criteria for substance abuse or dependence in the subject's opinion as documented by the investigator, and a positive result does not signal a clinical condition that would impact the subject safety or interpretation of the study results
  • Diagnosis of hematologic or solid malignancy within 5 years prior to screening. Subjects with a history of localized basal cell or squamous cell skin cancer may be included in the study if they are cancer-free prior to the screening visit for this study

Allergy and Adverse Reactions:

*. History of drug or other allergy that, in the opinion of the investigator, would make the subject unsuitable for participation in the study
