    ABSTRACT: To evaluate the efficacy and tolerability of sumatriptan, 50-mg and 100-mg tablets, compared with placebo for treatment of migraine at the first sign of pain. Two identical multicenter randomized, double-blind, placebo-controlled, single-attack studies were conducted from May through November 2000 in adults (aged 18-65 years). Patients treated migraine at the first sign of pain, while pain was mild, but not more than 2 hours after onset with oral sumatriptan, 50 mg or 100 mg, or matching placebo. The primary end point was pain-free relief at 2 hours after treatment with 50 mg of sumatriptan compared with placebo. There were 354 patients in study 1 and 337 patients in study 2. Significantly more patients treated with sumatriptan, 50 mg and 100 mg, were completely free from pain 2 and 4 hours after treatment vs patients treated with placebo (at 2 hours, 50% and 57% vs 29%; at 4 hours, 61% and 68% vs 30%; for both, P < .001). Also, significantly more patients treated with sumatriptan, 50 mg and 100 mg, were migraine-free (no pain or associated symptoms) vs those treated with placebo at 2 and 4 hours after treatment (at 2 hours, 43% and 49% vs 24%; at 4 hours, 54% and 63% vs 28%; for both, P < .001). The incidence of overall adverse events was low with the 50- and 100-mg dose of sumatriptan (placebo, 7%; sumatriptan at 50 mg, 14%; sumatriptan at 100 mg, 16%). Treatment of migraine at the first sign of pain with sumatriptan, 50-mg and 100-mg tablets, provides superior pain-free relief at 2 and 4 hours after treatment compared with placebo. Results of these studies suggest that sumatriptan at 100 mg may be more efficacious than at 50 mg when used in the early treatment paradigm. Because these studies were not powered to detect statistical differences between active doses, studies to investigate this finding are warranted.

    ABSTRACT: To describe the demographics and migraine characteristics of patients in the Glaxo Wellcome adolescent clinical trials' database. Data from 8 sumatriptan (tablet and nasal spray) and naratriptan (tablet) trials (6 placebo controlled and 2 open label) were reviewed. Adolescents aged 12 to 17 years who had participated in migraine clinical trials and used at least 1 dose of study medication were summarized using descriptive statistics. Patient demographic (gender, age, race, height, and weight) and migraine (diagnosis, pain location and intensity, time and day of migraine onset and treatment, and associated symptoms) characteristics were examined. One thousand nine hundred thirty-two adolescents with migraine were identified; mean age was 14.1 years (standard deviation, 1.64; range, 11 to 18) and 54% of patients were female. More males were represented in the 12- to 14-year-old group (646 [73%] of 885) than in the 15- to 17-year-old group (234 [26%] of 885). Most patients reported migraine without aura (67%, 1121 of 1672), unilateral migraine pain (58%, 458 of 787), and pulsating pain (74%, 582 of 790). Migraine was aggravated by physical activity in most of the adolescents (88%, 526 of 598). Most migraine attacks (73%, 1363 of 1858) began between 6 am and 6 pm, and proportionately more attacks occurred Monday through Wednesday. Pretreatment vomiting was experienced by 5% (97 of 1830) of patients, nausea by 53% (983 of 1849), and photophobia or phonophobia (or both) by 88% (1628 of 1858) of patients. The incidence of associated symptoms was directly related to pretreatment headache severity. In this large clinical trials' database, adolescents had migraine without aura characterized by unilateral and pulsating pain and aggravated by activity. The incidence of associated symptoms was directly related to pretreatment pain intensity. More migraines occurred Monday through Wednesday during typical school hours. These data may facilitate clinicians' efforts to tailor migraine therapy to the needs of this patient population.

    ABSTRACT: This study assessed the efficacy of sumatriptan 50- and 100-mg tablets in the treatment of migraine attacks while the pain is mild rather than moderate/severe. Results from The Spectrum Study suggested that early treatment of migraine attacks with sumatriptan 50-mg tablets while the pain is mild might enhance pain-free response and reduce headache recurrence. Retrospective analyses of headaches treated during mild pain were performed using data from 3 studies of sumatriptan tablets (protocols S2CM09, S2BT25, and S2BT26). Our primary interest was pain-free response 2 and 4 hours after dosing; secondary interests were use of a second dose of medication, clinical disability (as measured on a 4-point disability scale), migraine-associated symptoms, meaningful pain relief (patient defined), time to meaningful relief, sustained pain-free response, and proportion of attacks in which pain had worsened 2 and 4 hours after dosing, all of which were compared in headaches treated during mild versus moderate/severe pain. In S2CM09, 92 patients treated 118 headaches during mild pain. Rates of pain-free response were higher 2 hours after dosing with sumatriptan 50 mg (51%) or 100 mg (67%; P < 0.05) compared with placebo (28%), and were higher with early treatment of mild pain compared with treatment of moderate/severe pain at 2 hours (sumatriptan 50 mg: mild pain, 51%; moderate/severe pain, 31%; P < 0.05; sumatriptan 100 mg: mild pain, 67%; moderate/severe pain, 36%) and 4 hours (50 mg: 75% vs 56%; 100 mg: 90% vs 61%; P < 0.05). Early intervention also resulted in less redosing than when moderate/severe pain was treated (50 mg: 21% vs 32%; 100 mg: 20% vs 29%). More attacks treated early with sumatriptan 50 or 100 mg were associated with normal function 4 hours after dosing compared with placebo (70% and 93% vs 46%, respectively). Sustained pain-free response rates 2 to 24 hours after early dosing with sumatriptan 50 or 100 mg were also higher (34% and 53%, respectively) compared with treatment of moderate/severe pain (19% and 24%, respectively). Early treatment with sumatriptan 100 mg produced significantly higher pain-free rates at 2 hours after dosing (P < 0.001) than did ergotamine plus caffeine (S2BT25: 69% vs 34%, respectively) or aspirin plus metoclopramide (S2BT26: 73% vs 25%, respectively). Sumatriptan 50- and 100-mg tablets are effective whether pain is mild or moderate/severe. However, treatment with sumatriptan while pain is mild provides high pain-free response rates while reducing the need for redosing, benefits not seen with ergotamine plus caffeine or aspirin plus metoclopramide.

    ABSTRACT: To determine the effect of sumatriptan on migraine-related workplace productivity loss. In this randomized, double-blind, placebo-controlled, parallel-group trial, adult migraineurs self-injected 6 mg of sumatriptan or matching placebo to treat a moderate or severe migraine within the first 4 hours of a minimum of an 8-hour work shift. Outcome measures included productivity loss and number of patients returning to normal work performance 2 hours after injection and across the work shift, time to return to normal work performance, and time to headache relief. A total of 206 patients underwent screening, 140 (safety population) of whom returned for clinic treatment. Of these 140 patients, 119 received migraine treatment in the workplace (intent-to-treat population), 116 of whom comprised the study population. Of these 116 patients, 76 self-administered sumatriptan, and 40 self-administered placebo. Sumatriptan treatment tended to reduce median productivity loss 2 hours after injection compared with placebo (25.2 vs 29.9 minutes, respectively; P = .14). Significant reductions in productivity loss were obtained across the work shift after sumatriptan treatment compared with placebo (36.8 vs 72.6 minutes, respectively; P = .001). Significantly more sumatriptan-treated patients vs placebo-treated patients experienced shorter return to normal work performance at 2 hours (53/76 [70%] vs 12/40 [30%], respectively) and across the work shift (64/76 [84%] vs 23/40 [58%], respectively; P < .001). Significantly more sumatriptan-treated patients experienced headache relief 1 hour after injection compared with placebo-treated patients (48/76 [63%] vs 13/40 [33%], respectively; P = .004). Across an 8-hour work shift, sumatriptan was superior to placebo in reducing productivity loss due to migraine.
