Objective: We sought to evaluate temporal response patterns to erenumab treatment in patients with episodic migraine.

Background: Although many patients treated with erenumab experience onset of efficacy as early as 1 week, clinical benefits of migraine preventive therapies may accrue with continued treatment. Furthermore, details about the maintenance of clinical responses have not been reported.

Migraine involves brain hypersensitivity with episodic dysfunction triggered by behavioral or physiological stressors. During an acute migraine attack the trigeminal nerve is activated (peripheral sensitization). This leads to central sensitization with activation of the central pathways including the trigeminal nucleus caudalis, the trigemino-thalamic tract, and the thalamus.

Introduction/objective: Chronic migraine (CM) is associated with impaired health-related quality of life and substantial socioeconomic burden, but many people with CM are underdiagnosed and do not receive appropriate preventive treatment. OnabotulinumtoxinA and topiramate have demonstrated (treatment benefit under ideal conditions) for the prevention of headaches in people with CM in clinical trials, but real-world studies suggest markedly different clinical (treatment benefit based on a blend of efficacy and tolerability). This study sought to evaluate patient-reported outcomes (PROs) of onabotulinumtoxinA versus topiramate immediate release for people with CM.

Background: Migraine clinical profile may change with age, making it necessary to verify that migraine treatments are equally safe and effective in older patients. These analyses evaluated the effects of patient age on the pharmacokinetics (PK), efficacy, and safety of galcanezumab for prevention of migraine.

Methods: Analyses included efficacy data from three double-blind phase 3 clinical trials: two 6-month studies in episodic migraine (EVOLVE-1, EVOLVE-2: N = 1773) and one 3-month study in chronic migraine (REGAIN:N = 1113).

Background: We studied the efficacy and safety of a second dose of lasmiditan for acute treatment of migraine.

Methods: SAMURAI and SPARTAN were double-blind, placebo-controlled Phase 3 studies in which individuals with migraine were randomized to oral lasmiditan 50 mg (SPARTAN only), 100 mg, 200 mg, or placebo. Study drug was to be taken within 4 h (h) of onset of a migraine attack (moderate or severe pain).

Objective: To determine if baseline/interictal saliva calcitonin gene-related peptide (CGRP) levels would be lower in subjects with chronic migraine receiving onabotulinumtoxinA compared with those receiving saline.

Background: CGRP is considered central to the pathogenesis of episodic migraine, but its relationship to chronic migraine is less understood. OnabotulinumtoxinA is an effective treatment for chronic migraine and has been demonstrated to inhibit the vesicular release of CGRP.

Acute headache medication overuse (MO) is common in patients with chronic migraine (CM). We evaluated safety and efficacy of onabotulinumtoxinA as preventive treatment of headache in CM patients with baseline MO (CM+MO) in a planned secondary analysis from two similarly designed, randomized, placebo-controlled, parallel, Phase III trials. Patients were randomized to treatment groups (155-195 U of onabotulinumtoxinA or placebo) using MO (patient-reported and diary-captured frequency of intake) as a stratifying variable.

Objectives: To investigate the factors that influence a migraineur's beliefs regarding oral triptans for the acute treatment of migraines and to provide further insight into patients' decision-making process when faced with migraine.

Methods: A multicenter, cross-sectional, observational study of subjects currently prescribed an oral triptan medication for the acute treatment of migraine headaches. Subjects were recruited from 6 headache clinics and one primary care practice in the United States.

Objective: To investigate a broad definition of migraine resolution that extends beyond specific migraine-associated diagnostic symptoms as measured by the Completeness of Response Survey.

Methods: Conducted at 8 sites, 135 subjects treated migraines with SumaRT/Nap over 2 months. To measure subjects' experiences with SumaRT/Nap compared to their usual migraine medication, the Headache Impact Test, Revised Patient Perception of Migraine Questionnaire, and Completeness of Response Survey were administered at baseline and at 2 months.
