NCT04904328 | Unknown status | Migraine

A Proof of Concept Alleviating the Symptoms of Photosensitive Migraine.
Sponsor:

Mitsui Chemicals, Inc.

Brief Summary:

This proof of concept clinical study will investigate the efficacy of active lens with frame in alleviating the symptoms of migraine which are caused by photosensitivity. The spectacles cut out blue light wavelength and hypothetically alleviate symptoms of migraine and thus either treat or prevent migraine headaches from occurring.

Condition or disease

Migraine

Intervention/treatment

Lumishade® Active Lens

Lumishade® Sham Lens

Phase

Not Applicable

Detailed Description:

Patients will be randomised to one of two groups: Group 1 Patients wear sham glasses for 4 weeks Patients have 1 week's washout Patients wear active glasses for 4 weeks Group 2 Patients wear active glasses for 4 weeks Patients have 1 week's washout Patients wear sham glasses for 4 weeks The study will aim to determine whether wearing the active lens successfully reduces the symptoms of migraine, compared to wearing sham lens. Assuming a fairly conservative SD in the primary endpoint of 8 points, a total of 56 participants would be required to have 90% power to detect a minimum clinically significant difference of 5 points in a two-sample t-test. Allowing for a 20% drop-out rate, 70 participants would need to be recruited. Patients will be in the trial for a total of 13 weeks (4 week run-in, two 4 week periods, with 1 week washout in between).}}
