Effectiveness of galcanezumab on sleep quality, migraine outcome, and multidimensional patient-reported outcome measures: a real-world experience in Turkish patients with episodic and chronic migraine. Front Neurol 2024; 15:1411238. [PMID: 38887386 PMCID: PMC11180826 DOI: 10.3389/fneur.2024.1411238] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2024] [Accepted: 05/15/2024] [Indexed: 06/20/2024] Open
Abstract
Introduction This real-world study aimed to investigate the impact of galcanezumab on sleep quality, migraine outcome and multidimensional patient-reported outcomes measures (PROMs) in patients with episodic migraine (EM) and chronic migraine (CM). Methods Fifty-four patients with episodic migraine (n = 24) or chronic migraine (n = 30) received a 3-month series of galcanezumab injections and were evaluated for sleep quality, measured using the Pittsburgh Sleep Quality Index (PSQI), as well as migraine outcomes such as monthly headache days (MHDs), monthly migraine days (MMDs), and headache severity. Patient-reported outcome measures (PROMs) such as the Migraine Disability Assessment Scale (MIDAS), Headache Impact Test-6 (HIT-6), SF-36 Health-related Quality of Life (HRQoL), Beck Anxiety Inventory (BAI), and Beck Depression Inventory (BDI) were additionally included in the assessment. Results The percentage of patients with poor sleep quality (total PSQI scores ≥ 5) was 72.7% at baseline, decreasing to 57.5% and 56.2% at the 1st and 2nd months, respectively. By the 3rd month of galcanezumab injections, significant improvement was observed in the sleep disturbances domain in the overall study population (p = 0.016), and in subgroups of patients with low anxiety levels (p = 0.016) and none/minimal depression (p = 0.035) at baseline. Patients with sleep disorder at baseline exhibited marked improvements in total PSQI scores (p = 0.027) and in the subjective sleep quality (p = 0.034) and daytime dysfunction (p = 0.013) domains, by the 3rd month. Over the 1st, 2nd, and 3rd months, there were significant improvements in MHDs (p < 0.001), MMDs (p < 0.001), HIT-6 scores (p < 0.001 for each), BAI scores (p < 0.001 for each), BDI scores (p ranged from 0.048 to <0.001), and HRQoL scores (p ranged from 0.012 to <0.001). Conclusion Galcanezumab demonstrates notable benefits in improving sleep quality, along with a comorbidity-based and domain-specific effect on sleep parameters, which involved sleep disturbances domain in patients without depression or anxiety at baseline but the total PSQI scores, subjective sleep quality and daytime dysfunction in those with sleep disorder at baseline. The treatment also facilitates rapid-onset enhancements in migraine outcomes as well as various PROMs.

Abstract
INTRODUCTION Fremanezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide, is indicated for preventive treatment of migraine in adults. Real-world evidence assessing the effect of fremanezumab on migraine-related medication use, health care resource utilization (HCRU), and costs in patient populations with comorbidities, acute medication overuse (AMO), and/or unsatisfactory prior migraine preventive response (UPMPR) is needed. METHODS Data for this US, retrospective claims analysis were obtained from the Merative® MarketScan® Commercial and supplemental databases. Eligible adults with migraine initiated fremanezumab between 1 September 2018 and 30 June 2019 (date of earliest fremanezumab claim is the index date), had ≥ 12 months of continuous enrollment prior to initiation (preindex period) and ≥ 6 months of data following initiation (postindex period; variable follow-up after 6 months), and had certain preindex migraine comorbidities (depression, anxiety, and cardiovascular disease), potential AMO, or UPMPR. Changes in migraine-related concomitant acute and preventive medication use, HCRU, and costs were assessed pre- versus postindex. RESULTS In total, 3193 patients met the eligibility criteria. From pre- to postindex, mean (SD) per patient per month (PPPM) number of migraine-related acute medication and preventive medication claims (excluding fremanezumab), respectively, decreased from 0.97 (0.90) to 0.86 (0.87) (P < 0.001) and 0.94 (0.74) to 0.81 (0.75) (P < 0.001). Migraine-related outpatient and neurologist office visits, emergency department visits, and other outpatient services PPPM decreased pre- versus postindex (P < 0.001 for all), resulting in a reduction in mean (SD) total health care costs PPPM from US$541 (US$858) to US$490 (US$974) (P = 0.003). Patients showed high adherence and persistence rates, with mean (SD) proportion of days covered of 0.71 (0.29), medication possession ratio of 0.74 (0.31), and persistence duration of 160.3 (33.2) days 6 months postindex. CONCLUSIONS Patients with certain migraine comorbidities, potential AMO, and/or UPMPR in a real-world setting had reduced migraine-related medication use, HCRU, and costs following initiation of fremanezumab.

Abstract
INTRODUCTION In 2020, the Italian Medicines Agency (AIFA) approved the reimbursement of calcitonin gene-related peptide (CGRP) pathway monoclonal antibodies (mAbs), including fremanezumab, in patients with a Migraine Disability Assessment Scale (MIDAS) score ≥ 11, with prescription renewals for up to 12 months in patients with ≥ 50% reduction in MIDAS score at Months 3 and 6. In this sub-analysis of the Pan-European Real Life (PEARL) study, we provide real-world data on fremanezumab use in Italian routine clinical practice (EUPAS35111). METHODS This first interim analysis for Italy was conducted when 300 enrolled adult patients with episodic or chronic migraine (EM, CM) completed 6 months of treatment with fremanezumab. The primary endpoint is the proportion of patients achieving ≥ 50% reduction in monthly migraine days (MMD) across the 6 months post-fremanezumab initiation. Secondary endpoints include: proportion of patients achieving ≥ 50% reduction in MIDAS score at Months 3 and 6, and mean change from baseline across Months 1-6 in MMD and headache-related disability. Safety was assessed through adverse events (AEs) reported. RESULTS Of 354 patients enrolled at Italian centers, 318 (EM, 35.5%, CM, 64.5%) were included in the effectiveness analysis. Of patients with available data, 109 (61.2%) achieved the primary endpoint. 61.0% and 65.1% achieved ≥ 50% reduction in MMDs at Months 3 and 6, respectively; 79.9% and 81.0% experienced ≥ 50% reduction in MIDAS at the same timepoints. CONCLUSION Fremanezumab was effective and well-tolerated over the first 6 months of treatment, with approximately 80% of patients meeting Italian criteria for treatment continuation at Months 3 and 6.

Abstract
Background Calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) are indicated for migraine prevention in the United States. Limited data comparing real-world treatment patterns for CGRP mAbs are available. Objective To compare the treatment patterns among patients with migraine initiating galcanezumab, fremanezumab, and erenumab. Methods This retrospective study included adult patients with one or more claims for a self-injectable CGRP mAb (galcanezumab, fremanezumab, or erenumab), with continuous enrollment in medical and pharmacy benefits for 12 months pre-index and 6 and 12 months post-index using MerativeTM MarketScan® Commercial and Medicare databases from May 2017 through March 2021. Propensity-score matching was used to address confounding by observed covariates. Outcomes analyzed included proportion of days covered (PDC), medication-possession ratio (MPR), persistence (≤60-day gap), treatment discontinuation, and switch to a non-index drug. Descriptive X2 and t-test analyses were conducted. Results At the 12-month follow-up, matched galcanezumab and fremanezumab cohorts each comprised 2674 patients and the galcanezumab and erenumab cohorts 3503 each. The mean (SD) PDC and MPR were both 0.6 (0.3) across all cohorts. Based on PDC ≥0.80 and MPR ≥0.80, a greater proportion of galcanezumab vs fremanezumab (46.2% vs 43.7%, p=0.053; 46.8% vs 44.3%, p=0.053) and galcanezumab vs erenumab (46.2% vs 44%, p=0.156; 46.7% vs 44.5%, p=0.262), respectively, initiators were adherent. Compared to galcanezumab, fremanezumab (248.0 days vs 236.5 days, p=0.001), and erenumab (247.8 days vs 241.7 days, p=0.061) initiators had lower mean persistence. Galcanezumab initiators were less likely to discontinue treatment than fremanezumab (47.8% vs 51.7%, p=0.005) and erenumab (47.7% vs 50.2%, p=0.040) initiators. Across cohorts, most switchers initiated onabotulinum toxin A as subsequent treatment. Similar results were observed for 6-month follow-up cohorts. Conclusion Patients with migraine who initiated treatment with galcanezumab showed higher persistence and lower treatment discontinuation rates than those initiating either fremanezumab or erenumab.

Abstract
After 35 years since the introduction of the International Classification of Headache Disorders (ICHD), we are living in the era of the second great revolution in migraine therapies. First, discoveries of triptans provided a breakthrough in acute migraine treatment utilizing bench-to-bedside research results on the role of serotonin in migraine. Next, the discovery of the role of neuropeptides, more specifically calcitonin gene-related peptide (CGRP) in migraine attack led to the development of anti-CGRP therapies that are effective both in acute and preventive treatment, and are also able to reduce migraine-related burden. Here, we reviewed the most recent clinical studies and real-world data on available migraine-specific medications, including triptans, ditants, gepants and anti-CGRP monoclonal antibodies. Novel drug targets, such as PACAP and amylins were also discussed. To address the main challenges of migraine therapy, the high heterogeneity of people with migraine, the prevalent presence of various comorbid disorders, and the insufficient medical care of migraine patients were covered. Promising novel approaches from the fields of omics, blood and saliva biomarker, imaging and provocation studies might bring solutions for these challenges with the potential to identify further drug targets, distinguish more homogeneous patient subgroups, contribute to more optimal drug selection strategies, and detect biomarkers in association with headache features or predicting treatment efficacy. In the future, the combined analysis of data of different biomarker modalities with machine learning algorithms may serve precision medicine in migraine treatment.

Abstract
Migraine is a highly disabling and often chronic neurological disease that affects more than one billion people globally. Preventive migraine treatment is recommended for individuals who have frequent and/or disabling attacks; however, many of the medications used for migraine prevention (e.g., antiepileptics, antidepressants, antihypertensives) were not specifically developed for migraine, and often have limited efficacy or poor tolerability. Four monoclonal antibodies targeting the calcitonin gene-related peptide (CGRP) pathway, which is believed to play a crucial role in the pathophysiology of migraine, have been approved by the US Food and Drug Administration for the preventive treatment of migraine in adults. All four migraine-specific treatments have demonstrated efficacy based on reductions in monthly days with migraine for patients with both episodic and chronic migraine, including those with comorbidities. They have also demonstrated favorable safety and tolerability profiles. Based on these accounts, CGRP pathway-targeted monoclonal antibodies have the potential to revolutionize preventive treatment for patients with migraine.

Abstract
The result of more than thirty years of research, anti-CGRP monoclonal antibodies are currently the state of the art for migraine preventive therapy. Their efficacy and safety, supported by an already large and growing body of evidence, are added by many other advantages: an early onset of action, favorable posology, negligible pharmacological interaction, and a broad-reaching efficacy in many challenging clinical contexts. When compared to standard prophylactics, these novel medications seem at least as efficacious, clearly more tolerable and, consequently, with a superior adherence profile. Furthermore, recently published analyses indicate that they are cost-effective, especially among those with chronic migraine. Yet, current guidelines endorse their use only after multiple other preventives have failed or have been deemed not tolerable. Although this recommendation may have been sensible at first, the now available data strongly point that time has come for anti-CGRP monoclonal antibodies to be acknowledged as first-line treatments for migraine patients with severe disability. For these individuals, delaying treatment until several other alternatives have failed incurs in significant losses, both economically and to many relevant aspects of their lives.

Abstract
Background: Newly approved migraine preventive therapies have allowed for rapid control of migraine activity, offering potential to minimize the burden of migraine. This report summarizes a roundtable discussion convened to analyze evidence for early onset of prevention, ascertain its clinical relevance, and provide guidance for healthcare professionals in crafting goals and treatment expectations for patients with migraine initiating preventive therapy. Methods: A virtual roundtable meeting of migraine clinicians, researchers, and patient advocates convened in October 2020. Participants reviewed and discussed data summarizing patient and healthcare professional perceptions of migraine prevention and evidence from the peer-reviewed and gray literature to develop corresponding recommendations. Summary: Evidence from clinical studies of anti-calcitonin gene-related peptide monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) and the chemodenervation agent onabotulinumtoxinA indicate that patients may experience reduction of migraine activity within 7 days of drug administration and early attainment of disease control is associated with improvements in clinically important outcomes. The roundtable of experts proposes that early onset be defined as demonstration of preventive benefits within 1 week of treatment initiation. We recommend focusing discussion with patients around “disease control” and potential benefits of early onset of prevention, so patients can set realistic preventive therapy goals and expectations.

Abstract
Background Migraine preventive treatment with CGRP(−receptor) monoclonal antibodies (mAbs) has a positive effect on patients’ health-related quality of life (HRQoL). The German treatment guidelines recommend discontinuing successful treatment with CGRP(−receptor) mAbs after 6–12 months. We aimed to evaluate headache-specific and generic HRQoL for three months after discontinuation of CGRP(−receptor) mAb treatment. Methods We conducted a prospective, longitudinal cohort study, including patients with migraine after 8–12 months of therapy with a CGRP(−R) mAb and before a planned discontinuation attempt. HRQoL was assessed at the time of the last mAbs injection (V1), eight weeks later (V2), and sixteen weeks later (V3). For headache-specific HRQoL, we used the Headache Impact Test-6 (HIT-6). Generic HRQoL was determined with the EuroQol-5-Dimension-5-Level (ED-5D-5L) form, and the Short-Form 12 (SF-12), which comprises a Physical Component Summary (PCS-12) and a Mental Component Summary (MCS-12). Questionnaires’ total scores were compared across the three observation points using nonparametric procedures. Results The study cohort consisted of n = 61 patients (n = 29 treated with the CGRP-receptor mAb erenumab and n = 32 with the CGRP mAbs galcanezumab or fremanezumab). The HIT-6 sum score was 59.69 ± 6.90 at V1 and increased by 3.69 ± 6.21 at V3 (p < 0.001), indicating a greater headache impact on patients’ lives. The mean total EQ-D5-L5 score declined from 0.85 ± 0.17 at V1 by − 0.07 ± 0.18 at V3 (p = 0.013). Both Mental and Physical Component Scores of the SF-12 worsened significantly during treatment discontinuation: The PCS-12 total score decreased by − 4.04 ± 7.90 from V1 to V3 (p = 0.013) and the MCS-12 score by − 2.73 ± 9.04 (p = 0.003). Changes in all questionnaires’ scores but the MCS-12 were already significant in the first month of the drug holiday (V2). Conclusions Our results show a significant decline in headache impact and generic HRQoL of migraine patients after treatment discontinuation of a CGRP(−R) mAb. The observed deterioration is above the established minimally clinically important differences for each of the questionnaires and can therefore be considered clinically meaningful. Monitoring HRQoL during a discontinuation attempt could facilitate the decision whether or not to resume preventive treatment with CGRP(−R) mAbs.

Abstract
Ajovy (fremanezumab, Teva Pharmaceuticals, Israel) is a fully humanized monoclonal antibody that selectively binds both isoforms of the calcitonin gene-related peptide. Calcitonin gene-related peptide is a 37-amino acid neuropeptide involved in central and peripheral pathophysiological events in migraine. It is indicated for prophylaxis of migraine in adults who have at least four migraine days per month, and can be administered as a subcutaneous injection using an autoinjector device, with two dosing options: 225 mg once a month or 675 mg quarterly. In this article, I present data from Phase III clinical trials of fremanezumab in episodic and chronic migraine, in which fremanezumab demonstrated efficacy and had a favorable tolerability profile, with no serious treatment-related adverse events.

Abstract
Fremanezumab is a humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide and is approved in Europe for migraine prevention in adults with ≥4 migraine days/month. The Pan-European Real Life (PEARL) study is a 24-month, prospective, observational study of fremanezumab in chronic or episodic migraine. End points include proportion of patients with ≥50% reduction in monthly migraine days during 6 months of treatment (primary); changes in monthly migraine days, disability scores and acute headache medication use; adherence and persistence; and effectiveness in patients switching from another calcitonin gene-related peptide pathway-targeting monoclonal antibody. PEARL is being conducted in approximately 100 centers in 11 European countries (estimated n = 1100). PEARL will generate important real-world data on effectiveness of fremanezumab and treatment patterns in patients with chronic migraine or episodic migraine.
