Avulux™ is intended to decrease the impact of headache and migraine on normal daily life and the ability to function, and reduce the frequency and severity of headache, in adult patients diagnosed with episodic migraine headache or chronic migraine.
Avulux™ consists of a pair of optical filters in the form of spectacle lenses, provided in standard spectacle frames or as clip-on units, coated with a thin film 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.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 60 participants |
Allocation: | Randomized |
Intervention Model: | Crossover Assignment |
Intervention Model Description: | A total of 50 subjects will be randomized into one of two treatment groups in a one-to-one ratio. After three weeks, and following a one-week washout period, subjects will be given spectacles from the other treatment group |
Masking: | Triple (Participant, Care Provider, Investigator) |
Masking Description: | The active and sham lenses will have tints calibrated such that the optical density, that is the overall "darkness" of all study lenses, will be the same. All study lenses will appear to have the same overall light-blocking effect to study subjects. |

Experimental: Avulux Spectacles
Subjects will be instructed to use the spectacles for three weeks. They will be instructed to put the spectacles on at the first signs or symptoms of their migraine attacks. This could be their usual aura, or the first signs of their headache commencing, and to keep the spectacles on until their headache has resolved.

- Headache Impact Test (HIT-6) total score [ Time Frame: Three-week ]The primary objective of this study is to evaluate the efficacy of the Avulux device in reducing the impact of migraine headaches as measured by improvement in Headache Impact Test (HIT-6) scores at three weeks when compared to a control/sham device. HIT-6 scores range from 36 to 78. Higher scores indicate a greater impact of headaches on the respondent's life, i.e., 36 = no impact, 78 = maximum impact.
- Number and Severity of Headache Days [ Time Frame: Three-week ]To measure effects on the number and severity of headaches, we will use the subjects' daily diaries to count the number of days with headache that either a) made activity difficult, b) caused activity changes, or c) caused patient to go to bed. We will then compare the proportion of days with headaches that met one of these criteria for the 4-week baseline period and the 3-week intervention.
- Proportion of subjects who were able to move out of the "very severe impact" category of the HIT-6 during the 3-week intervention [ Time Frame: Three-week ]Compare initial vs. final HIT-6 scores for each treatment period
- Proportion of patients who experienced at least a 5-point improvement in their HIT-6 score during the 3-week intervention [ Time Frame: Three-week ]Compare initial vs. final HIT-6 scores for each treatment period
- Proportion of days with headaches which lead to use of medications to control the headache over the 3-week intervention [ Time Frame: Three-week ]Compare diaries for treatment vs. control periods to determine proportion of headaches resolved by device vs. device plus medication
- Proportion of days with light sensitivity over the 3-week intervention [ Time Frame: Three-week ]Compare diaries for treatment vs. control periods to determine differences in days with light sensitivity.
- Average Number of Hours Slept over the 3-week intervention [ Time Frame: Three-week ]Compare diaries for treatment vs. control periods to determine whether a significant difference exists in number of hours slept between treatment groups.
