Psychological predictors of negative treatment outcome with Erenumab in chronic migraine: data from an open label long-term prospective study.

ABSTRACT:

Background

Monoclonal antibodies (mABs) targeting the calcitonin gene-related peptide (CGRP) pathway represent the first disease-specific preventive migraine therapy. Growing evidence suggests that they are effective in the preventive treatment of difficult-to-treat patients. In this study, we evaluated the psychological predictors of the outcome of treatment with the anti-CGRP monoclonal antibody erenumab in patients with chronic migraine (CM).

Methods

Seventy-five patients with CM who had already failed at least 3 preventive therapies received erenumab every 28 days for a period of 12 months. Before the first administration, patients received a full psychological evaluation using The Structured Clinical Interview for DSM-5 Clinician Version (SCID-5-CV) to assess personality disturbances (primary outcome), mood and anxiety disorders, and as well specific questionnaires to evaluate alexithymia traits, childhood traumas, and current stressors (secondary outcomes).

Results

After 12 months of treatment, 53 patients reported a reduction of at least 50% in headache days/per month (Responders), whereas 22 did not (Non Responders). When compared to Responders, Non Responders were characterized by a higher prevalence of personality disorders belonging to Cluster C (avoidant, dependent, and obsessive-compulsive) (77% vs 37%, p = .001). Non Responders were also characterized by a higher prevalence of anxiety disorders (90% vs 60%, p = 0.007), showed more alexithymic traits (51.7 ± 13.7 vs 42.9 ± 14.3, p = 0.017), and reported a higher number of 'at least serious' current stressors (3.2 ± 4.0 vs 0.8 ± 1.4, p < .0001) than Responders. At the multivariate analysis, higher prevalence of Cluster C personality disorders (OR 3.697; p = 0.05) and higher number of 'at least serious' life events (OR 1.382; p = 0.017) arose as prognostic factors of erenumab failure.

Conclusions

Erenumab confirmed its effectiveness in a population of difficult-to-treat migraine. The presence of "anxious-fearful" personality together with current stressors and anxiety represent negative predictors of treatment outcome.

Trial registration

The study protocol was registered at clinicaltrials.gov ( NCT04361721 ).

Project description:ObjectiveTo assess long-term (up to 2 years) efficacy, tolerability, and safety of erenumab for the prevention of episodic migraine (EM) in Japanese patients.BackgroundPreviously published results from the double-blind treatment phase (DBTP) of a phase 2 clinical study have demonstrated the efficacy and safety of erenumab in Japanese patients with EM.MethodsPatients completing the 24-week placebo-controlled DBTP could continue into the 76-week open-label treatment phase (OLTP), receiving erenumab 70 mg or 140 mg subcutaneously once monthly. The initial dose in the OLTP was erenumab 70 mg monthly, which was later changed to 140 mg. After study completion, the following were assessed: change from baseline in monthly migraine days (MMD), change from baseline in monthly acute migraine-specific medication days (MSMD), percentage of patients achieving ≥50% and ≥75% reduction in MMD, change from baseline in the 6-item Headache Impact Test (HIT-6™) score, and safety (exposure-adjusted patient-incidence of adverse events [AEs], calculated as number of patients per 100 patient-years).ResultsOf 475 patients enrolled in the DBTP, 459 (96.6%) continued in the OLTP. The mean (SD) MMD was 7.9 (2.3) at baseline with the overall change from baseline at week 100 of -2.9 (4.1) days. The monthly acute MSMD was 5.7 (2.8) at baseline with change from baseline at week 100 of -1.7 (3.7) days. The proportion of patients who achieved ≥50% and ≥75% reduction in MMD from baseline at week 100 was 177/398 (44.5%) and 94/398 (23.6%), respectively. The HIT-6™ score was 58.4 (5.4) at baseline with a change of -6.4 (8.2) at week 100. The exposure-adjusted patient-incidence of AEs during the OLTP was 207.1/100 patient-years for the combined erenumab group, similar to that observed for either erenumab (271.0/100 patient-years) or placebo (257.3/100 patient-years) during the DBTP, and no new safety signals were detected during the OLTP.ConclusionLong-term erenumab treatment in Japanese patients with EM demonstrated sustained efficacy for up to 2 years, with a safety profile similar to previous studies, supporting erenumab as a potential new therapy for EM prevention in Japan.

Project description:BACKGROUND:Galcanezumab, a humanized monoclonal antibody that selectively binds to the calcitonin gene-related peptide, has demonstrated in previous Phase 2 and Phase 3 clinical studies (?6-month of treatment) a reduction in the number of migraine headache days and improved patients' functioning. This study evaluated the safety and tolerability, as well as the effectiveness of galcanezumab for up to 12 months of treatment in patients with migraine. METHODS:Patients diagnosed with episodic or chronic migraine, 18 to 65 years old, that were not exposed previously to galcanezumab, were randomized to receive galcanezumab 120 mg or 240 mg, administered subcutaneously once monthly for a year. Safety and tolerability were evaluated by frequency of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and adverse events (AEs) leading to study discontinuation. Laboratory values, vital signs, electrocardiograms, and suicidality were also analyzed. Additionally, overall change from baseline in the number of monthly migraine headache days, functioning, and disability were assessed. RESULTS:One hundred thirty five patients were randomized to each galcanezumab dose group. The majority of patients were female (>?80%) and on average were 42 years old with 10.6 migraine headache days per month at baseline. 77.8% of the patients completed the open-label treatment phase, 3.7% of patients experienced an SAE, and 4.8% discontinued due to AEs. TEAEs with a frequency???10% of patients in either dose group were injection site pain, nasopharyngitis, upper respiratory tract infection, injection site reaction, back pain, and sinusitis. Laboratory values, vital signs, or electrocardiograms did not show anyclinically meaningful differences between galcanezumab dosesOverall mean reduction in monthly migraine headache days over 12 months for the galcanezumab dose groups were 5.6 (120 mg) and 6.5 (240 mg). Level of functioning was improved and headache-related disability was reduced in both dose groups. CONCLUSION:Twelve months of treatment with self-administered injections of galcanezumab was safe and associated with a reduction in the number of monthly migraine headache days. Safety and tolerability of the 2 galcanezumab dosing regimens were comparable. TRIAL REGISTRATION:ClinicalTrials.gov as NCT02614287 , posted November 15, 2015.

Project description:Objective To evaluate the efficacy and tolerability of single pulse transcranial magnetic stimulation (sTMS) for the preventive treatment of migraine. Background sTMS was originally developed for the acute treatment of migraine with aura. Open label experience has suggested a preventive benefit. The objective of this trial was to evaluate the efficacy and tolerability of sTMS for migraine prevention. Methods The eNeura SpringTMS Post-Market Observational U.S. Study of Migraine (ESPOUSE) Study was a multicenter, prospective, open label, observational study. From December 2014 to March 2016, patients with migraine (n = 263) were consented to complete a 1-month baseline headache diary followed by 3 months of treatment. The treatment protocol consisted of preventive (four pulses twice daily) and acute (three pulses repeated up to three times for each attack) treatment. Patients reported daily headache status, medication use, and device use with a monthly headache diary. The primary endpoint, mean reduction of headache days compared to baseline, was measured over the 28-day period during weeks 9 to 12. The primary endpoint was compared to a statistically-derived placebo estimate (performance goal). Secondary endpoints included: 50% responder rate, acute headache medication consumption, HIT-6, and mean reduction in total headache days from baseline of any intensity. Results Of a total of 263 consented subjects, 229 completed a baseline diary, and 220 were found to be eligible based on the number of headache days. The device was assigned to 217 subjects (Safety Data Set) and 132 were included in the intention to treat Full Analysis Set. For the primary endpoint, there was a -2.75 ± 0.40 mean reduction of headache days from baseline (9.06 days) compared to the performance goal (-0.63 days) ( p < 0.0001). The 50% responder rate of 46% (95% CI 37%, 56%) was also significantly higher ( p < 0.0001) than the performance goal (20%). There was a reduction of -2.93 (5.24) days of acute medication use, headache impact measured by HIT-6, -3.1 (6.4) ( p < 0.0001), and total headache days of any intensity -3.16 days (5.21) compared to the performance goal (-0.63 days) ( p < 0.0001). The most common adverse events were lightheadedness (3.7%), tingling (3.2%), and tinnitus (3.2%). There were no serious adverse events. Conclusions This open label study suggests that sTMS may be an effective, well-tolerated treatment option for migraine prevention. Trial registration number NCT02357381.

Project description:ObjectiveTo examine the cardiovascular, cerebrovascular, and peripheral vascular safety of erenumab across migraine prevention studies.MethodsVascular adverse events (AEs) and blood pressure data were integrated across 4 double-blind, placebo-controlled studies of erenumab and their open-label extensions in patients with chronic or episodic migraine. Subgroup analyses were conducted by acute migraine-specific medication use and number of vascular risk factors at baseline. Standardized search terms were used to identify vascular AEs (cardiovascular, cerebrovascular, or peripheral). An independent committee adjudicated whether targeted events were vascular in origin.ResultsIn placebo-controlled studies, 2,443 patients received placebo (n = 1,043), erenumab 70 mg (n = 893), or erenumab 140 mg (n = 507) subcutaneously once monthly. Regardless of acute migraine-specific medication use or vascular risk factors at baseline, AE incidence was similar across the placebo and erenumab treatment groups. Hypertension AEs were reported for 0.9% (placebo), 0.8% (erenumab 70 mg), and 0.2% (erenumab 140 mg) of patients. Vascular AEs, which were similar across double-blind and open-label treatment, generally were confounded, with plausible alternative etiologies. In 18 patients with events reviewed by the independent committee, 4 events were positively adjudicated as cardiovascular in origin: 2 deaths and 2 vascular events. All 4 positively adjudicated cardiovascular events occurred during open-label erenumab treatment.ConclusionSelective blockade of the canonical calcitonin gene-related peptide receptor with erenumab for migraine prevention had a vascular safety profile comparable to that of placebo over 12 weeks, with no increased emergence of events over time. Further study of long-term safety of erenumab in patients with migraine is needed.Clinicaltrialsgov identifiersNCT02066415, NCT02456740, NCT01952574, NCT02483585, NCT02174861, and NCT01723514.Classification of evidenceThis analysis provides Class II evidence that for patients with migraine, erenumab does not increase the risk of vascular AEs.

Project description:PurposeMigraine 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.MethodsCGAJ 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.ResultsA 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).ConclusionGalcanezumab 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.
