Pilot Study of Two Different Strengths of DFN-11 Injection for Rapidly Escalating Migraine

Exclusion Criteria

• •1. Inability to distinguish migraine from other primary headaches
• •2. Experiences headache of any kind at a frequency greater than or equal to 15 days per month
• •3. Chronic opioid therapy (\> 10 days in the 30 days prior to screening)
• •4. Current treatment with monoamine oxidase A (MAO-A) inhibitors or use within 4 weeks before randomization
• •5. Hemiplegic or basilar migraine
• •6. History, symptoms or signs of ischemic cardiac, cerebrovascular or peripheral vascular syndromes
• •7. Uncontrolled hypertension (screening systolic/diastolic blood pressure \> 140/90 mmHg in 2 out of 3 readings)
• •8. History of epilepsy or conditions associated, which in the opinion of the Investigator, increase the likelihood of present day seizure
• •9. History (within 2 years) of drug or alcohol abuse as defined by DSM-IV-TR criteria.
• •10. Systemic disease, which in the opinion of the Investigator, would contraindicate participation
• •11. History of a neurological or psychiatric condition, which in the opinion of the Investigator would contraindicate participation
• •12. Pregnant or lactating women
• •13. Have taken any investigational medication within 30 days before randomization, or are scheduled to receive an investigational drug
• •14. Subjects with a positive urine drug screen for recreational drugs or marijuana (whether legal or not) or for prescription drugs not explained by stated concomitant medications
• •15. Clinical laboratory or electrocardiogram (ECG) abnormality that in the opinion of the Investigator would endanger the subject or interfere with the study conduct. If the results of the clinical laboratory or ECG are outside of normal reference range the subject may still be enrolled but only if these findings are determined to be not clinically significant by the Investigator. This determination must be recorded in the subject's source document prior to enrolment.
• •16. Fridericia's corrected QT (QTcF) interval greater than 450 msec
• •17. Severe renal impairment (creatinine \> 2 mg/dl)
• •18. Serum total bilirubin \> 2.0 mg/dL
• •19. Serum aspartate aminotransferase (AST), alanine aminotransferase (ALT), or alkaline phosphatase \> 2.5 times the upper limit of normal
• •20. Subjects who in the opinion of the investigator experience rebound headache from caffeine usage
