Validation and meaningful within-patient change in work productivity and activity impairment questionnaire (WPAI) for episodic or chronic migraine.

Background: No available studies demonstrate validity and meaningful change thresholds of Work Productivity and Activity Impairment (WPAI) questionnaire in patients with migraine. In this post-hoc analysis, we assessed reliability, validity, responsiveness, and meaningful within-patient change from baseline to Month 3 for Work Productivity and Activity Impairment (WPAI) domain scores in patients with episodic migraine (EM) or chronic migraine (CM).

Method: The Phase 3, multicenter, randomized, double-blind, placebo-controlled CONQUER study (NCT03559257, N = 462) enrolled patients with EM or CM who failed two to four categories of prior preventive medication in past ten years.

Psychometric validation and meaningful within-patient change of the Migraine-Specific Quality of Life questionnaire version 2.1 electronic patient-reported outcome in patients with episodic and chronic migraine.

Objective: To evaluate the measurement properties of all three domains of the Migraine-Specific Quality of Life questionnaire version 2.1 (MSQ v2.1) electronic patient-reported outcome (ePRO) to assess the functional impact of migraine in patients with episodic or chronic migraine (CM); and identify meaningful within-patient change thresholds for the Role Function-Restrictive (RFR), Role Function-Preventive (RFP), and Emotional Function (EF) domains.

Migraine Headache Day Response Rates and the Implications to Patient Functioning: An Evaluation of 3 Randomized Phase 3 Clinical Trials of Galcanezumab in Patients With Migraine.

Objective: This post hoc study investigated the relationship between patient response in terms of migraine headache day reduction and patient-reported outcomes of health-related quality of life (HRQoL) and disability categories.

Background: Migraine causes considerable disease-related disability and negatively impacts HRQoL of patients. Calcitonin gene-related peptide inhibitors improve these outcomes and may eliminate disability due to migraine in some patients.

Functional impairment and disability among patients with migraine: evaluation of galcanezumab in a long-term, open-label study.

Purpose: Migraine can negatively impact patient functioning and quality of life. Here, we report the effects of galcanezumab (GMB), a humanized monoclonal antibody that binds to calcitonin gene-related peptide, on patient-reported outcome (PRO) measures in migraine.

Methods: CGAJ was a Phase III, randomized, open-label study (12-month open-label and 4-month post-treatment follow-up) in patients with episodic or chronic migraine.

A Qualitative Study to Assess the Content Validity of the 24-Hour Migraine Quality of Life Questionnaire in Patients with Migraine.

Objective: A concept elicitation, cognitive debriefing, and usability study was undertaken to: (1) explore migraine symptoms and day-to-day impacts; (2) determine the comprehensiveness and comprehensibility of the previously developed 24-Hour Migraine Quality of Life Questionnaire electronic patient-reported outcome (24-Hr MQoLQ ePRO) items, and the appropriateness and understanding of the recall period, response options, and instructions; and (3) assess the usability on an electronic hand-held device.

Methods: Eleven United States English-speaking people with episodic migraine were recruited to participate in one-on-one interviews, which followed methods appropriate for concept elicitation, cognitive debriefing, and usability testing. Interviews were audio-recorded, transcribed, and analyzed following the constant comparative method.

Content validity of the Migraine-Specific Quality of Life Questionnaire version 2.1 electronic patient-reported outcome.

Purpose: A concept elicitation, cognitive debriefing, and usability study was undertaken to: 1) ascertain the migraine experience with a particular focus on the impact on roles and daily functioning; 2) determine the comprehensiveness and comprehensibility of the Migraine-Specific Quality of Life Questionnaire version 2.1 electronic patient-reported outcome Role Function-Restrictive (MSQ v2.1 ePRO RFR) domain items, and the appropriateness and understanding of the recall period, response options, and instructions; and 3) assess the usability on an electronic tablet device.

Two randomized migraine studies of galcanezumab: Effects on patient functioning and disability.

Objective: To evaluate changes from baseline in patient-reported outcomes for measures of functioning and disability among patients with migraine treated with galcanezumab or placebo.

Methods: Patients with episodic migraine (4-14 monthly migraine headache days) were treated with either galcanezumab (Evaluation of LY2951742 in the Prevention of Episodic Migraine [EVOLVE]-1: 120 mg n = 210, 240 mg n = 208; EVOLVE-2: 120 mg n = 226, 240 mg n = 220) or placebo (EVOLVE-1 n = 425; EVOLVE-2 n = 450) during 6 months of treatment. Migraine-Specific Quality of Life Questionnaire v2.

Psychometric Validation of the Role Function Restrictive Domain of the Migraine Specific Quality-of-Life Questionnaire Version 2.1 Electronic Patient-Reported Outcome in Patients With Episodic and Chronic Migraine.

Objectives: To assess the measurement properties of the Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) electronic patient-reported outcome (ePRO) Role Function-Restrictive (RFR) domain to evaluate the functional impact of migraine in patients with episodic (EM) or chronic migraine (CM) enrolled in clinical trials.

Measures of Functioning in Patients With Episodic Migraine: Findings From a Double-Blind, Randomized, Placebo-Controlled Phase 2b Trial With Galcanezumab.

Objective - To evaluate 12-week changes from baseline of 2 disease-specific patient-reported outcome (PRO) measures in adults with migraine treated with galcanezumab, an investigational humanized antibody binding calcitonin gene-related peptide (CGRP), or placebo. Background - Preventing headache-related functional impairment is an important goal of migraine preventive treatment and a measurement target for PROs. Understanding which drugs have the potential to improve patient functioning in addition to preventing migraine headaches is vital to lessening patient burden.
