AIM: The aim of this article is to evaluate the safety and efficacy of perimenstrual telcagepant , a CGRP receptor antagonist, for headache prophylaxis. METHODS: We conducted a randomized, double-blind, placebo -controlled, six-month trial in women with migraine for ≥ 3 months who experienced perimenstrual headaches . Women were randomized to telcagepant 140 mg or placebo (2:1 ratio) for seven consecutive days perimenstrually. Safety was assessed by adverse events and laboratory tests . The primary efficacy endpoint was mean monthly headache days in the subset of women reporting perimenstrual migraine (-2 days to +3 days of menses onset) and ≥ 5 moderate or severe migraines per month prior to entering the trial. RESULTS: Telcagepant was generally well tolerated : 66/2660 (2.5%) on telcagepant and 36/1326 (2.7%) on placebo discontinued because of a clinical adverse event. The percentages of patients with clinical adverse events, laboratory adverse events, or discontinuation because of a laboratory adverse event were also similar between treatments. Alanine aminotransferase elevations ≥ 3x normal occurred in 0.6% of women on telcagepant and 0.4% on placebo . Three women on telcagepant vs none on placebo had alanine aminotransferase elevations ≥ 8× normal. In the efficacy subset there was no significant effect of telcagepant (n = 887) vs placebo (n = 447) in mean monthly headache days (treatment difference -0.5 day (95% CI: -1.1, 0.1)). However, telcagepant was associated with a reduction in on-drug headache days (treatment difference -0.4 day (95% CI: -0.5, -0.2), nominal p < 0.001). CONCLUSIONS: Telcagepant 140 mg taken perimenstrually for seven days was generally well tolerated , but was associated with transaminase elevations . Telcagepant did not reduce monthly headache frequency , but did reduce perimenstrual headaches . © International Headache Society 2015.
