Use of the Avulux® Lenses as an Aid in Reducing the Impact of Migraine Headaches

Study Overview
=================
Brief Summary
-----------------
The purpose of this research is to assess how well the Avulux® migraine lenses work in reducing the impact of migraine headaches as measured by improvement in an 11-point pain scale after two and four hours of device application, when compared to a control device.

Detailed Description
-----------------
Avulux® is intended to reduce the severity of headache pain in adult patients diagnosed with episodic migraine headaches. In this study, the investigative Avulux® device shall consist of a pair of optical filters in the form of spectacle lenses, provided in a standard spectacle frame; the lenses contain a dye that effectively blocks light at specified wavelength ranges while minimizing distortion of the visible spectrum. The optical filters block a portion of the optical spectrum that is suspected to stimulate photophobic responses that trigger some, and exacerbate most, migraines. The control/sham device for this study shall be a pair of plastic lenses provided in a standard spectacle frame, which will have negligible light-blocking properties at the optical wavelengths which are blocked by the Avulux® device.

Interventional Model Description: A minimum of 68 subjects will be randomized in to one of two treatment groups in a one-to-one ratio.
Masking: Triple


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Avulux® device<br>Subjects will be instructed to use the glasses for four weeks. They will be instructed to put the glasses on at the first signs or symptoms consistent with the onset of a migraine attack or at the first onset of aura and keep the glasses on until their headache has resolved. | Other: 11-point pain scale<br>* Subjects will be asked to rate their headache pain using an 11-point scale, i.e. on an integer scale from 0 to 10 inclusive, with 0 indicating no pain and 10 indicating the worst pain imaginable.<br>Other: Headache diary<br>* Subjects will be asked to record specific information for the first (and all subsequent) severe or very severe migraine headaches that they experience while enrolled in the study.<br>Device: Avulux®<br>* Avulux® device<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in 11-point Pain Scale Score After Two Hours (First Severe Headache) | Change in migraine pain from baseline to 2 hours after device application, based on first severe or very severe migraine headache experienced by a study subject (i.e. baseline pain score of 6 or higher). Pain scale is an 11-point scale, with integer values from 0 (no pain) to 10 (worst pain imaginable) inclusive. | from baseline to 2 hours after device application | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in 11-point Pain Scale Score After Four Hours (First Severe Headache) | Change in migraine pain from baseline to 4 hours after device application, based on first severe or very severe migraine headache experienced by a study subject (i.e. baseline pain score of 6 or higher). Pain scale is an 11-point scale, with integer values from 0 (no pain) to 10 (worst pain imaginable) inclusive. | from baseline to four hours after device application |
