title: RPR100893, a substance-P antagonist, is not effective in the treatment of migraine attacks.
abstract: A global, double-blind, randomized, placebo-controlled, dose-finding, parallel-group trial was conducted to compare three oral doses of RPR100893 (1, 5, 20 mg), a substance-P antagonist, and placebo in 139 patients with migraine attacks with moderate or severe headache intensity. Headache intensity and improvement of headache after 2 h were not different in the four treatment groups. Therefore, it is concluded that this oral substance-P antagonist in the doses used here is not effective.
