Long-term treatment with lasmiditan in patients with migraine: Results from the open-label extension of the CENTURION randomized trial.

BACKGROUND: Following the CENTURION phase 3 randomized controlled trial's four-month double-blind phase, this 12-month open-label extension collected data for up to one year about dose optimization, patterns of use, migraine-related disability, and quality of life during lasmiditan treatment. METHODS: Migraine patients ≥18 years completing the double-blind phase and treating ≥3 migraine attacks could continue into the 12-month open-label extension. The initial oral lasmiditan dose was 100 mg; the dose could subsequently be adjusted to 50 mg or 200 mg at the investigator's discretion. RESULTS: 477 patients entered and 321 (72.1%) completed the extension; 445 (93.3%) treated ≥1 attack with lasmiditan. Of 11,327 attacks, 8654 (76.4%) were lasmiditan-treated (84.9% of these involved moderate or severe pain). By study end, 17.8%, 58.7%, and 23.4% of patients were taking lasmiditan 50, 100, and 200 mg, respectively. Mean improvements were observed in disability and quality of life. The most common treatment-emergent adverse event was dizziness (35.7% of patients, 9.5% of attacks). CONCLUSIONS: During this 12-month extension, lasmiditan was associated with a high rate of study completion, most attacks were treated with lasmiditan, and patients reported improvements in migraine-related disability and quality of life. No new safety findings were observed with longer exposure.Trial registration: ClinicalTrials.gov (NCT03670810); European Union Drug Regulating Authorities Clinical Trials Database (EUDRA CT: 2018-001661-17).

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. METHODS: Data were drawn from three double-blind, placebo-controlled, and randomized Phase 3 clinical studies (episodic migraine [EM]: EVOLVE-1 and EVOLVE-2; CM: REGAIN). The psychometric properties of the MSQ v2.1 ePRO domains were demonstrated by evaluating reliability (internal consistency and test-retest), construct validity (convergent and known groups), and responsiveness. Meaningful within-patient change thresholds for domains were estimated using anchor-based approaches, supplemented by empirical cumulative distribution function curves and probability density function plots to enable interpretation of meaningful change over 3 months. The Patient Global Impression of Severity (PGI-S) and Patient Global Impression of Improvement served as anchors. RESULTS: A total of 2,850 patients with either EM (EVOLVE-1: 851; EVOLVE-2: 909) or CM (REGAIN: 1,090) were included. The Cronbach's alpha estimates of internal consistency exceeded the recommended threshold of ≥0.70 for all domains from the three studies, indicating adequate internal consistency. Test-retest reliability intraclass correlation coefficients were ≥0.80 for all domains across all three studies, demonstrating almost perfect agreement. Convergent validity was supported by moderate-to-strong correlation (r ≥ 0.30) between all domains of MSQ v2.1 ePRO and studied anchors (Migraine Disability Assessment Score and PGI-S scores) across all three studies. Known group validity was established between all domains and subgroups of patients stratified by baseline PGI-S scores and baseline number of monthly migraine headache days for all three studies. The 3-month meaningful within-patient change thresholds were the same for EM and CM for RFP: 20.00 and EF: 26.67; and for RFR: 25.71. CONCLUSIONS: These findings demonstrate that all three domains of the MSQ v2.1 ePRO have sufficient reliability, validity, responsiveness, and appropriate interpretation standards. Our results suggest that MSQ v2.1 ePRO is a well-defined and reliable patient-reported outcome instrument that is suitable for use in clinical studies for evaluating the impact of migraine on patient functioning in episodic and CM.

Changes in patient functioning and disability: results from a phase 3, double-blind, randomized, placebo-controlled clinical trial evaluating galcanezumab for chronic migraine prevention (REGAIN).

PURPOSE: To evaluate secondary outcomes including changes in functioning and disability associated with galcanezumab, a humanized monoclonal antibody to calcitonin gene-related peptide, in patients with chronic migraine. METHODS: Patients randomly received galcanezumab (120 mg n = 278, 240 mg n = 277) or placebo (n = 558) during 3 months of double-blind treatment, followed by a 9-month open-label extension. The Migraine-Specific Quality-of-Life Questionnaire v2.1 (MSQv2.1) measured the impact of migraine on patient functioning. The Migraine Disability Assessment (MIDAS) quantified headache-related disability. Changes from baseline were analyzed with mixed model repeated measures or analysis of covariance. RESULTS: Total MSQ score at baseline was 44.88 ± 18.02 (mean ± SD), indicating significant functional impairment. At Month 3, least squares (LS) mean change ± SE in total MSQ for galcanezumab-treated patients were 20.51 ± 1.49 (120 mg) and 20.49 ± 1.49 (240 mg), both statistically significantly greater vs placebo-treated patients (14.55 ± 1.21; both P < 0.001). Total MIDAS score at baseline was 67.24 ± 57.31 (mean ± SD). At Month 3, LS mean change ± SE from baseline in total MIDAS for galcanezumab-treated patients was statistically significantly greater than placebo for 120 mg group (placebo: - 11.53 ± 3.38 vs 120 mg: - 20.27 ± 4.07; P < 0.05) but not for 240 mg group (- 17.02 ± 4.05). At Month 12, within-group mean changes from baseline for total MSQ (28.56 ± 1.19 previous placebo; 29.53 ± 1.51 previous 120 mg; 25.83 ± 1.49 previous 240 mg) and MIDAS scores (- 28.47 ± 2.95 previous placebo; - 31.47 ± 3.69 previous 120 mg; - 31.13 ± 3.62 previous 240 mg) were statistically significant (P < 0.001) for the open-label treatment population regardless of previous double-blind treatment assignment. CONCLUSIONS: Galcanezumab-treated patients with chronic migraine reported statistically significant improvements in functioning and disability, representing a clinically significant change. TRIAL REGISTRATION: ClinicalTrials.gov registry: NCT02614261. Registered 25 November 2015.

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. Patients aged 18-65 years with diagnosis of migraine (≥ 4 migraine headache days per month) as defined by International Classification of Headache Disorders (ICHD)-3 beta guidelines were included in the study. Patients were randomized 1:1 with subcutaneous GMB 120 mg (with a loading dose of 240 mg) or GMB 240 mg given once monthly for 12 months. Changes from baseline in PRO measures such as Migraine-Specific Quality of Life Questionnaire v2.1 (MSQ) and Migraine Disability Assessment (MIDAS) were assessed. RESULTS: A total of 135 patients were randomized to each galcanezumab dose group. Mean (SD) baseline MSQ total scores were 53.85 (20.34) [GMB 120 mg] and 53.69 (18.79) [GMB 240 mg]. For MIDAS, mean (SD) total scores were 45.77 (42.06) [GMB 120 mg] and 53.96 (61.24) [GMB 240 mg]. Within-group mean improvement from baseline on MSQ and MIDAS total scores and all individual item/domain scores were statistically significant for both GMB dose groups, at all-time points during the treatment phase (p < 0.001). For MSQ domain scores, greatest improvement was observed in the Role function-restrictive (RF-R) domain (overall least squares (LS) mean change ± SE: 31.55 ± 1.20 [GMB 120 mg] and 33.40 ± 1.16 [GMB 240 mg]). For MIDAS, the overall LS mean change ± SE from baseline across the entire 12-month treatment phase in total scores were: -33.58 ± 2.11 (GMB 120 mg) and -32.67 ± 2.04 (GMB 240 mg). CONCLUSION: Galcanezumab was associated with statistically significant changes from baseline in the PRO measures across the entire 12-month treatment period. These results indicate improved health-related quality of life and decreased disability among patients treated with galcanezumab.

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. RESULTS: Participants had a mean age of 42 years, and 8 were female. Through spontaneous mention or probing, all concepts of the 24-Hr MQoLQ ePRO were endorsed by a majority of the participants. Cognitive interviewing confirmed the 24-Hr MQoLQ ePRO instructions were clear, meaningful, and important to assess as symptoms and day-to-day impacts experienced as a result of migraine. Overall impressions of the ePRO device were overwhelmingly favorable, and the ePRO device was preferred to paper and pencil by all participants. Participant responses regarding the level of headache pain that would be acceptable in order to continue to go about daily activities ranged from 3 to 6, on a scale of 0 to 10, with 0 being "no headache" and 10 being "the worst headache." CONCLUSIONS: The 24-Hr MQoLQ ePRO is content-valid and appropriate for inclusion in future acute treatment for migraine studies designed to measure the symptoms and health-related quality of life of migraine.

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. METHODS: Analyses used data from 3 double-blind, placebo (PBO)-controlled, phase 3 studies in adults with episodic migraine (EM) (EVOLVE-1: N = 858 and EVOLVE-2: N = 915) or chronic migraine (CM) (REGAIN: N = 1113). Patients were randomized 2:1:1 to subcutaneous injection of PBO, galcanezumab (GMB) 120 mg, or GMB 240 mg once monthly for 6 months in EVOLVE-1 and -2 and for 3 months in REGAIN. Primary endpoint was overall mean change from baseline in monthly migraine headache days. Patients were divided into 4 response-level groups based on percent change from baseline (<30%, ≥30% to <50%, ≥50% to <75%, ≥75%). Patient-reported outcomes included the 14-item Migraine-Specific Quality of Life Questionnaire version 2.1 (MSQ) and Migraine Disability Assessment (MIDAS) questionnaire. RESULTS: Among patients with migraine, mean improvements from baseline in MSQ domain scores increased with each successive level of migraine headache day response. On a 100-pt scale, increases in Role Function-Restrictive score in EM were 16.8 and 36.0 at the <30% and ≥75% response levels, respectively, and for CM were 10.7 and 46.5. Similar patterns in scores were observed for the Role Function-Preventive and Emotional Function domains. Examination of improvement in MSQ item score by treatment group showed that, in patients with EM, approximately 10 to 20% more GMB-treated patients (N = 796 for GMB 120 mg and GMB 240 mg) had improvements in all 14 MSQ items compared with PBO-treated patients (N = 773) (all P < .001). In patients with CM, 3 to 16% more GMB-treated patients (N = 507) had improvements in the 14 MSQ items compared with PBO (N = 494), though differences were statistically significant in only 19 of 28 comparisons. At baseline, mean MIDAS scores (EM, 33.1; CM, 67.2) indicated severe mean disability for patients with EM and very severe disability for patients with CM. Among patients with EM, 215 of 425 (50.6%) of those treated with GMB 120 mg and 212 of 413 (51.3%) treated with 240 mg had little/no disability due to migraine after 6 months (PBO: 277 of 832 (33.3%), P < .001 for both). Among patients with CM, 50 of 254 (19.7%) of those treated with GMB 120 mg and 54 of 258 (20.9%) treated with 240 mg reached the level of little/no disability after 3 months of treatment (PBO: 70 of 504 (13.9%), P = .045 for 120 mg, P = .017 for 240 mg). CONCLUSIONS: Because migraine greatly impairs an individual's ability to participate in activities of daily living, measurements of HRQoL are essential in clinical research. This study showed that function in daily life, as measured by MSQ score, improved as migraine headache days were reduced and that GMB-treated patients were more likely to see improvement in MSQ item scores compared with PBO-treated patients. Elimination of migraine-related disability was also more frequent in GMB-treated patients compared with placebo-treated patients.

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. METHODS: The 7-item MSQv2.1 ePRO RFR measures the functional impact of migraine on relationships with family and friends, leisure time, work or daily activities, productivity, concentration, tiredness, and energy. Measurement properties of the RFR were assessed using data from 2 EM (CGAG [n = 851] and CGAH [n = 909]) and 1 CM (CGAI [n = 1090]) Phase 3 galcanezumab clinical trials. Anchor- and distribution-based analyses were utilized to derive a responder threshold for clinical interpretation of change over time. The Migraine Disability Assessment (MIDAS), Patient Global Impression of Severity (PGI-S), Patient Global Impression of Improvement (PGI-I), and migraine headache days (MHD) served as anchors. Responsiveness and responder threshold analyses were completed from baseline to the average of months 4-6 for EM studies, and from baseline to month 3 for the CM study; timeframes selected were based on the primary endpoints in these studies. RESULTS: Cronbach's alpha values for internal consistency reliability were 0.93, 0.92, and 0.92, for CGAG, CGAH, and CGAI, respectively. Test-retest reliability intra-class correlation coefficients were 0.82 and 0.84 for CGAG and CGAH, and 0.85 for CGAI in stable patients. Convergent validity was supported by moderate to strong correlations (≥0.30) between the RFR and both MIDAS and PGI-S. Known-groups validity was established between subgroups stratified by baseline PGI-S and MHD (P < .05; δ = 0.35-1.96). For the EM studies, anchor variables suggested a change of ≥25 points (equivalent to 9 points/state changes on raw scale) in the RFR was an appropriate threshold to interpret a treatment benefit. For the CM study a change of ≥17.14 points (6 points/state changes on raw scale) was an appropriate threshold. In all 3 studies, significantly (P < .01) more galcanezumab patients achieved the responder definition thresholds, as compared to placebo (odds ratios of 1.98, 2.45, 2.27, 2.44, 1.64, and 1.66 for the 120 and 240 mg arms in the CGAG, CGAH, and CGAI trials, respectively). CONCLUSION: The MSQv2.1 ePRO RFR has sufficient reliability, validity, responsiveness, and appropriate interpretation standards for use in EM and CM clinical trials to assess the functional impact of migraine.

Patterns of practice in community mental health treatment of adult depression.

OBJECTIVE: Community mental health therapists often endorse an eclectic orientation, but few studies reveal how therapists utilize elements of evidence-based psychotherapies. This study aimed to characterize treatment as usual patterns of practice among therapists treating depressed adults in community mental health settings. METHOD: Therapists (N = 165) from the USA's largest not-for-profit provider of community-based mental health services completed surveys assessing their demographics and practice element use with depressed adult clients. Specifically, therapists indicated whether they utilized each of 45 unique practice elements from the following evidence-based psychotherapies: Acceptance and Commitment Therapy, Behavioral Activation, Brief Psychodynamic Therapy, Cognitive Behavioral Therapy (CBT), Interpersonal Therapy, Mindfulness-Based CBT, Problem-Solving Therapy, and Self-Control Therapy. Principal component analysis was employed to identify practice patterns. RESULTS: The principal component analysis included 31 practice elements and revealed a three-factor model with distinct patterns of practice that did not align with traditional evidence-based practice approaches, including: (i) Planning, Practice, and Monitoring; (ii) Cognitive, Didactic, and Interpersonal; and (iii) Between Session Activities. CONCLUSIONS: Therapist-reported practice patterns confirmed an eclectic approach that brought together elements from theoretically distinct evidence-based psychotherapies. Future research is needed to explore how these patterns of practice relate to client outcomes to inform focused training and/or de-implementation efforts.

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. Design/Methods - This Phase 2b double-blind, randomized, placebo-controlled study enrolled adults with episodic migraine. Galcanezumab (120 mg subcutaneous injection; n = 60) or placebo (n = 127) was administered every 28 days for 12 weeks. Post hoc secondary analyses were conducted for those who completed 12 weeks of treatment on 2 PROs: The Migraine-Specific Quality of Life Questionnaire (MSQ) v2.1 and the Headache Impact Test™ (HIT-6). Results - Analysis of covariance revealed significant differences in least square mean changes from baseline between galcanezumab and placebo for all MSQ domains including total mean change placebo of 18.63, galcanezumab of 27.36 (95% CI 2.449, 15.008; P-value of .0067); Role Function-Restrictive mean change placebo of 22.40, galcanezumab of 31.92 (95% CI 2.636, 16.518; P-value of .0071); Role Function-Preventive mean change placebo of 13.43, galcanezumab of 19.76 (95% CI 0.476, 12.185; P-value of .0342); and Emotional Function mean change placebo of 16.88, galcanezumab of 26.61 (95% CI 2.789, 16.674; P-value of .0063). At baseline, mean number of migraine headache days (MHDs) did not correlate with MSQ total scores or HIT-6. At 12 weeks post-treatment, MHD correlated with MSQ and HIT-6 scores (all P < .0001). Change in MHD was associated with change in MSQ domains and change in HIT-6 scores (all P < .0001). Conclusions - In comparison with placebo, treatment with galcanezumab was associated with significant functional improvements as reflected by changes in MSQ scores. Change in MHD was associated with improvements in MSQ and reductions in HIT-6 scores, indicating the clinical importance of these changes in relation to PROs that measure function.

Validation of the NetSCID: an automated web-based adaptive version of the SCID.

The present study developed and validated a configurable, adaptive, web-based version of the Structured Clinical Interview for DSM, the NetSCID. The validation included 24 clinicians who administered the SCID and 230 participants who completed the paper SCID and/or the NetSCID. Data-entry errors, branching errors, and clinician satisfaction were quantified. Relative to the paper SCID, the NetSCID resulted in far fewer data-entry and branching errors. Clinicians 'preferred' using the NetSCID and found that the NetSCID was easier to administer.

Maintenance treatment with varenicline for smoking cessation in patients with schizophrenia and bipolar disorder: a randomized clinical trial.

IMPORTANCE: It is estimated that more than half of those with serious mental illness smoke tobacco regularly. Standard courses of pharmacotherapeutic cessation aids improve short-term abstinence, but most who attain abstinence relapse rapidly after discontinuation of pharmacotherapy. OBJECTIVE: To determine whether smokers diagnosed with schizophrenia and bipolar disease have higher rates of prolonged tobacco abstinence with maintenance pharmacotherapy than with standard treatment. DESIGN, SETTING, AND PARTICIPANTS: Randomized, double-blind, placebo-controlled, parallel-group, relapse-prevention clinical trial conducted in 10 community mental-health centers. Of 247 smokers with schizophrenia or bipolar disease recruited from March 2008-April 2012, 203 received 12-weeks' open-label varenicline and cognitive behavioral therapy and 87 met abstinence criteria to enter the relapse prevention intervention. INTERVENTIONS: Participants who had 2 weeks or more of continuous abstinence at week 12 of open treatment were randomly assigned to receive cognitive behavioral therapy and double-blind varenicline (1 mg, 2 per day) or placebo from weeks 12 to 52. Participants then discontinued study treatment and were followed up to week 76. MAIN OUTCOMES AND MEASURES: Seven-day rate of continuous abstinence at study week 52, the end of the relapse-prevention phase, confirmed by exhaled carbon monoxide. Secondary outcomes were continuous abstinence rates for weeks 12 through 64 based on biochemically verified abstinence and weeks 12 through 76, based on self-reported smoking behavior. RESULTS: Sixty-one participants completed the relapse-prevention phase; 26 discontinued participation (7 varenicline, 19 placebo) and were considered to have relapsed for the analyses; 18 of these had relapsed prior to dropout. At week 52, point-prevalence abstinence rates were 60% in the varenicline group (24 of 40) vs 19% (9 of 47) in the placebo group (odds ratio [OR], 6.2; 95% CI, 2.2-19.2; P < .001). From weeks 12 through 64, 45% (18 of 40) among those in the varenicline group vs 15% (7 of 47) in the placebo group were continuously abstinent (OR, 4.6; 95% CI, 1.5-15.7; P = .004), and from weeks 12 through 76, 30% (12 of 40) in the varenicline group vs 11% (5 of 47) in the placebo group were continuously abstinent (OR, 3.4; 95% CI, 1.02-13.6; P = .03). There were no significant treatment effects on psychiatric symptom ratings or psychiatric adverse events. CONCLUSIONS AND RELEVANCE: Among smokers with serious mental illness who attained initial abstinence with standard treatment, maintenance pharmacotherapy with varenicline and cognitive behavioral therapy improved prolonged tobacco abstinence rates compared with cognitive behavioral therapy alone after 1 year of treatment and at 6 months after treatment discontinuation.

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. The analyses were performed for WPAI domain scores (absenteeism, presenteeism, overall work productivity, and non-work-related activity impairment). Migraine Specific Quality of Life Questionnaire version 2.1 (MSQv2.1) domain scores (Role Function-Restrictive [RFR] and Role Function-Preventive [RFP]), and monthly migraine headache days were used as anchors. Responder criteria were changes from baseline to Month 3 for each of these anchors and were defined as: increase in MSQ-RFR by ≥ 25.71 points and MSQ-RFP by ≥ 20.00 points and a 50% reduction in monthly migraine headache days. Assessments were performed for overall population, and patients with EM or CM. The meaningful change threshold was determined based on Youden index, Phi coefficient and sensitivity. RESULTS: Of 462 randomized patients, 444 who completed WPAI questionnaire were included in post-hoc analysis. Test-retest reliability over 3 months in a stable subgroup revealed moderate correlations for non-work-related Activity Impairment (ICC = 0.446) presenteeism (ICC = 0.438) and a fair correlation for overall work productivity loss (ICC = 0.360). At baseline, all correlations between WPAI domain scores and continuous anchor variables exceeded recommended threshold of ≥ 0.30, except for WPAI domain scores with number of monthly migraine headache days. Patients achieving pre-specified responsiveness thresholds for monthly migraine headache days, and MSQ-RFP, MSQ-RFR from baseline to Month 3 (responders) showed significant improvements in WPAI domain scores compared with non-responders (P < 0.001). The meaningful change thresholds of -20 (% unit) were identified for WPAI domain scores. CONCLUSION: In conclusion, WPAI has sufficient validity, reliability, responsiveness, and appropriate interpretation standards to assess the impact of EM or CM on presenteeism and overall work productivity loss and non-work-related activity impairment. TRIAL REGISTRATION: NCT number of CONQUER study, NCT03559257.

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. METHODS: Eleven US English-speaking people with episodic or chronic migraine were recruited to participate in one-on-one interviews, encompassing methods appropriate for concept elicitation, cognitive debriefing, and usability testing. Interviews were audio-recorded, transcribed, and analyzed following the constant comparative method. RESULTS: Participants (seven episodic and four chronic) had a mean age of 34.8 years, and nine were female. Through spontaneous mention or probing, the concepts of the MSQ v2.1 ePRO RFR domain items were described and endorsed by all participants as day-to-day functioning restrictions; except for item 5 (ability to concentrate), which was endorsed by 10 of 11 participants. Cognitive interviewing confirmed the MSQ v2.1 ePRO instructions were clear, meaningful, and important to assess as daily functioning impacts experienced as a result of migraine. Overall impressions of the ePRO device were favorable, and no participants reported any difficulties with use. CONCLUSIONS: The MSQ v2.1 ePRO RFR domain is content-valid and appropriate for inclusion in future studies designed to measure the functional impact of episodic or chronic migraine on the performance of day-to-day activities.

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 v2.1 (MSQv2.1) measured the effect of migraine on patient functioning (physical and emotional) in 3 domains, and the Migraine Disability Assessment (MIDAS) quantified headache-related disability associated with missed or reduced productivity at work or home and social events. Both were collected at baseline and during the treatment period (MSQv2.1 = monthly; MIDAS = months 3 and 6 only). RESULTS: Differences in MSQv2.1 total score least squares (LS) mean change from baseline (month 4-6) for galcanezumab (120 and 240 mg, respectively) were superior to placebo (EVOLVE-1 = 7.3 and 6.7 [both p < 0.001]; EVOLVE-2 = 8.5 and 7.3 [both p < 0.001]). Differences were similar for all domain scores (p < 0.001 for both galcanezumab doses compared with placebo), were observed as early as month 1, and were sustained for 6 months for most domains. Differences of MIDAS LS mean change from baseline (month 6) for galcanezumab (120 and 240 mg, respectively) compared with placebo were: EVOLVE-1 = -6.3 (p < 0.001) and -5.2 (p = 0.002); EVOLVE-2 = -9.2 and -8.2 (both p < 0.001). CONCLUSIONS: Patients with episodic migraine treated with galcanezumab reported significant and clinically meaningful improvements in daily functioning and decreased disability compared with patients who received placebo. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for patients with migraine, galcanezumab (120 mg or 240 mg) given once monthly improved functioning and reduced disability.

The InterSePT suicide scale for prediction of imminent suicidal behaviors.

The present study examined the ability of the International Suicide Prevention Trial (InterSePT) Scale for Suicidal Thinking (ISST) and the Calgary Depression Scale (CDS) to predict suicide attempts or hospitalizations to prevent attempts (referred to as Type 1 events) during the InterSePT trial [Meltzer, H.Y., Alphs, L., Green, A.I., Altamura, A.C., Anand, R., Bertoldi, A., Bourgeois, M., Chouinard, G., Islam, M.Z., Kane, J., Krishman, R., Lindenmayer, J.P., Potkin, S., 2003. Clozapine treatment for suicidality in schizophrenia. Archive of General Psychiatry 60, 82-91]. The primary goal of this analysis was to determine if the ISST and CDS ratings indicated that the raters, an unblinded (UP) and a blinded psychiatrist (BP) using the ISST, and a blinded rater using the CDS, were able to identify those patients who had a Type 1 event. The ratings of patients adjudged to have experienced a Type 1 event (Group 1) were compared with patients who did not (Group 2). The ISST and the CDS ratings obtained 2-8 weeks prior to a Type 1 event (Pre-1) and Pre-2, the rating immediately prior to Pre-1, obtained 2-12 weeks before Pre-1, were analyzed to test the hypothesis that the difference between Pre-2 and Pre-1 ratings for the Group 1 patients was significantly greater than the difference in the comparable ratings for Group 2 patients. The prediction that patients with Type 1 events would show greater worsening in ISST and CDS ratings between Pre-2 and Pre-1 than the Group 2 patients was confirmed. However, the sensitivity and specificity of a worsening in ratings was not sufficient to provide definitive warning of an impending Type 1 event. Other characteristics of the patients with Type 1 events provide additional warning: e.g. overall higher ratings on these scales, slower improvement in suicidality during treatment, and previous number of suicide attempts. These results indicate that the ISST and CDS may provide some additional information that can assist clinical decision making regarding suicidal risk in patients with schizophrenia or schizoaffective disorder.
