Study Overview
=================
Brief Summary
-----------------
This is a prospective, randomized, vehicle-controlled, double-blind, multi-center study assessing the safety, tolerability, and efficacy of B244 delivered as an intranasal spray for preventive treatment in subjects with episodic migraine.

Detailed Description
-----------------
This is a Prospective, Randomized, Vehicle-controlled, Double-blind, Multi-center, 3-arm study assessing the safety, tolerability, and efficacy of B244 delivered as an intranasal spray for preventive treatment in subjects with episodic migraine. At Screening and Baseline, all subjects must experiences 4-14 migraine days per month and 3-14 migraine attacks per month and no more than 14 headache days per month in the 3 months prior to screening. The total duration of the study will be approximately 16 weeks. Participants will report for a Screening visit and if all inclusion criteria are met, subjects will go through a one month baseline period prior to randomization. Subjects will come in for visits at Day 28 (Week 4), Day 56 (Week8), Day 84 (Week12), and Day 112 (Week 16). Efficacy will be assessed by change in migraine attacks, days, and hours. Blood and urine samples will be collected for standard safety laboratory testing and the effect of the drug on inflammatory biomarkers. Safety will be monitored throughout the study. Investigators plan to enroll 303 total subjects. Subjects will be randomized 1:1:1 so that an equal number of subjects will be treated in each arm of the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Treatment-related Adverse Events as Assessed by CTCAE v4.0 | Safety and tolerability endpoints will consist of all adverse events reporting during the study duration. | Baseline to Day 112 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Mean Change in Monthly Migraine Days. | Subjects made daily entries to include recordings of migraine frequency, duration, and severity that included information on migraine days (experiencing migraine with or without aura in a given day). | Baseline to Day 84 | 
| Mean Change in Monthly Migraine Attacks. | Subjects made daily entries to include recordings of migraine frequency, duration, and severity that included information on migraine attacks (an episode of any qualified migraine headache. To distinguish an attack of long duration from two attacks or to distinguish between attacks and relapses: A migraine attack that is interrupted by sleep, or temporarily remits, and then recurs within 48 hours (i.e., <48 hours between the start of the migraine attack to the time of the recurrence) will be considered as one attack and not two. -An attack treated successfully with medication but with relapse within 48 hours (i.e., <48 hours between the start of the migraine attack to the time of recurrence) will be considered as one attack.) | Baseline to Day 84 | 
| Proportion of Subjects Experiencing a 50%, 75%, and 100% Reduction in Monthly Migraine Days. | Subjects made daily entries to include recordings of migraine frequency, duration, and severity that included information on migraine days (experiencing migraine with or without aura in a given day). | Baseline to Day 112 | 
| Mean Change in Monthly Acute Migraine Specific Medication Days. | Subjects made daily entries to include recordings of migraine frequency, duration, and severity that included use of rescue (acute migraine specific) medications and dosing administration. | Baseline to Day 84 | 
| Mean Change in Monthly Headache Days. | Subjects made daily entries to include recordings of migraine frequency, duration, and severity that included information on headache days (a non-migraine headache day) | Baseline to Day 84 | 
| Mean Change From Baseline to 12 Weeks of Treatment in Disability, as Measured by the Migraine Disability Assessment (MIDAS) | The Migraine Disability Assessment (MIDAS) questionnaire was administered to study examine the relationship between the impact of migraine and quality of life where subjects scored 5 questions on a scale of 0 to 21+ (0-5=little or no disability, 6-10=mild disability, 11-20=moderate disability, 21+=severe disability). The total score ranges from 0 to 90. | Baseline to Day 84 | 
| Mean Change From Baseline to 12 Weeks of Treatment in Monthly Headache Impact Test-6 (HIT-6) Questionnaire | The Headache Impact Test-6 (HIT-6) questionnaire was administered to examine the relationship between impact of migraine and quality of life. The total score ranges from 36 to 78 where a higher score indicates a greater impact on quality of life (Class I: 36-49, Class II: 50-55, Class III: 56-59, Class IV: 60+). | Baseline to Day 84 | 
| Mean Change From Baseline to 12 Weeks of Treatment in Monthly Migraine Specific Quality of Life Questionnaire (MSQL) | The Migraine Specific Quality of Life (MSQL) questionnaire was used to examine the impact of migraine on health-related quality of life across three domains: Role Function-Restrictive (7 questions) examines the degree to which performance of daily activities is limited by migraine; Role Function-Preventive (4 questions) examines the degree to which performance of daily activities is prevented by migraine; Emotional Function (3 questions) examines feelings of frustration and helplessness due to migraine. Total score for each domain ranges from 0 to 100, where a higher score indicates greater severity. | Baseline to Day 84 |
