Objective:
To compare the efficacy and clinical benefit of 2 paradigms of migraine prevention using pre-emptive frovatriptan and daily topiramate. The study compares the paradigms of pre-emptive use of frovatriptan, a drug approved for acute migraine, and the daily use of topiramate, a Federal Drug Administration-approved and -accepted standard for migraine prophylaxis.
Background:
Traditionally, preventive treatment of migraine required daily medication. However, recent studies suggest that pre-emptive prophylaxis may be beneficial to those migraineurs who can predict an attack of migraine based on premonitory symptoms and treat during that phase.
Methods:
A total of 76 adult subjects with a diagnosis of migraine were screened for the study. During a 1-month baseline period, subjects demonstrated through a daily diary that they predicted at least 50% of migraine attacks during the premonitory phase and treated with their usual medication. Of these, 55 were randomized to either Group A (daily topiramate) or Group B (frovatriptan during premonitory symptoms); 44 completed the study. The treatment period lasted 2 months. The subjects answered the Migraine-Specific Quality of Life Questionnaire at randomization, and at Weeks 4 and 8. The revised Patient Perception of Migraine Questionnaire was answered 24 hours after taking frovatriptan (Group A, for break-through headaches; Group B, treatment during premonitory symptoms).
Results:
The number of migraine attacks and headache days per month decreased significantly from baseline for both Groups A and B. Subjects in Group A had considerably more adverse events leading to study withdrawal than in Group B (18% vs 4%). Though this study was not powered to directly compare the efficacy of the 2 drugs, topiramate showed superiority over frovatriptan at Month 2 in reduction of headache days, which was a secondary end point in the study (P = .036).
Conclusions:
This pilot study demonstrated that statistical benefit for reduction of headache days over baseline for both pre-emptive frovatriptan and daily topiramate. Subjects utilizing pre-emptive frovatriptan experienced fewer adverse events leading to study withdrawal. Subjects utilizing daily topiramate had fewer headache days at Month 2.
