In the last 15 years relevant efforts have been made to demonstrate that calcitonin gene-related peptide (CGRP) antagonism is a valuable and druggable mechanism for treatment or prevention of migraine. Galcanezumab is one of the antibodies developed and studied to prevent migraine by targeting CGRP. The scope of this review is to report data currently available on galcanezumab. According to available data, galcanezumab is safe and efficacious in preventing migraine in episodic migraine patients, ...[more]

Project description:BackgroundGalcanezumab, a humanized monoclonal antibody that selectively binds to calcitonin gene-related peptide, has demonstrated a significant reduction in monthly migraine headache days in phase 2 and 3 trials. In these analyses, we aimed to evaluate the safety and tolerability of galcanezumab compared with placebo for prevention of episodic or chronic migraine.MethodsData were integrated from three double-blind clinical studies for the up to 6-month galcanezumab exposure group (N = 1435), and from five clinical studies for the up to 1-year all-galcanezumab exposure group (N = 2276). Patients received a monthly 120 mg subcutaneous injection of galcanezumab (with a 240 mg loading dose in month 1), 240 mg galcanezumab, or placebo. Outcomes measured were treatment-emergent adverse events (TEAEs), serious AEs (SAEs), and discontinuation due to AEs (DCAEs). Laboratory results, vital signs, electrocardiogram (ECG), suicidal ideation and behavior results were evaluated.ResultsTEAEs that occurred more frequently in galcanezumab-treated patients included injection site pain, injection site reactions excluding pain, constipation, vertigo, and pruritus. The proportion of DCAEs among galcanezumab-treated patients ranged between 1.8 and 3.0%, and differed from placebo group for galcanezumab 240 mg (P < 0.05). Fewer than 2.0% of patients in either galcanezumab dose-group compared with 1.0% of placebo-treated patients reported a SAE. There were no clinically meaningful differences between galcanezumab and placebo in laboratory measures, vital signs including blood pressure, ECGs, cardiovascular-related AEs, or suicidal ideation and behavior.ConclusionsGalcanezumab demonstrated a favorable safety and tolerability profile for up to 1 year of treatment for the prevention of migraine.Trial registrationClinical Trials CGAB = NCT02163993, EVOLVE-1 = NCT02614183, EVOLVE-2 = NCT02614196, REGAIN = NCT02614261, and CGAJ = NCT02614287.

Project description:Background There are no reports on the effectiveness of one-time use of the calcitonin gene-related peptide-related monoclonal antibodies (CGRP-mABs) evaluated at one and three months for migraine prevention. Here, we present the real-world data of one-time administration of CGRP-mABs, galcanezumab and fremanezumab, for migraine prevention. Methodology We retrospectively investigated eight migraine patients treated with one-time administration of galcanezumab 240 mg or fremanezumab 225 mg. Monthly headache days (MHD), monthly acute medication intake days (AMD), and Headache Impact Test-6 (HIT-6) scores before, one, and three months after one-time CGRP-mABs administration were evaluated. Results A total of five women and three men were included (median age = 46.5 years, range = 19-63 years). Overall, six were episodic migraine, and two were chronic migraine. Five patients received one-time administration of fremanezumab and three received galcanezumab. In total, six (75.0%) patients experienced therapeutic effectiveness one month after the one-time administration. Five of the six maintained the therapeutic effect until three months, but one had aggravation. As a result, six (75.0%) patients reached or maintained therapeutic conditions three months after the one-time administration of CGRP-mABs without side effects. All patients continued previously used oral prophylaxis during the observational period. Significant reductions in MHD, AMD, and HIT-6 scores were observed three months after the initial administration (p = 0.008, p = 0.005, and p < 0.001, respectively). Conclusions Six of the eight patients experienced or maintained therapeutic effectiveness at three months despite the one-time administration of CGRP-mABs. Our results suggest that one-time use of CGRP-mABs may be a new treatment option in combination with oral prophylaxis.

Project description:BackgroundMonoclonal antibodies (mAbs) targeting the CGRP pathway are safe and efficacious therapies for the prevention of migraine. In this study we assessed the effects of discontinuation of preventive erenumab and galcanezumab treatment in patients with chronic migraine.MethodsThis retrospective pooled analysis included completers of the open-label extension study phase for the preventive treatment of chronic migraine with galcanezumab (NCT02614261; 9 months) and erenumab (NCT02174861; 12 months) in a single headache center. We compare migraine data until week 12 after open-label treatment completion, when patients did not have any pharmacological preventive medication, to study baseline values of the double-blind trial period, and to the last 4 weeks of the open-label extension. The assessment included changes in monthly migraine days, headache hours, days with severe headache and acute headache medication use.ResultsData from 16 patients after galcanezumab (n = 9) and erenumab (n = 7) open-label treatment completion were analyzed. The mean number of monthly migraine days was 18.38 ± 3.74 at baseline, and 12.19 ± 4.53 in the last 4 weeks of the open-label extension (p < 0.001). Monthly migraine days remained significantly reduced compared to baseline during the entire 12-week observation period after open-label termination (p = 0.002), with a reduction of 5.38 ± 4.92 in weeks 1-4 (p = 0.001), 4.75 ± 4.15 in weeks 5-8 (p = 0.001), and 3.93 ± 5.45 in weeks 9-12 (p = 0.014). There was no significant difference in monthly migraine days between the 12 weeks after open-label termination and the last 4 weeks of the open-label phase (p = 0.228). All other analyses revealed numerical improvement through week 12 in comparison to baseline.ConclusionsIn this small, self-selected cohort, the results indicate a therapeutic effect of monoclonal antibodies targeting the CRGP pathway in chronic migraine prevention after treatment termination up to 12 weeks.

Project description:PURPOSE OF REVIEW:This is a comprehensive review of the current literature on the usage of galcanezumab for migraine treatment. It reviews the biology, pathophysiology, epidemiology, diagnosis, and conventional treatment of migraines, then compares the literature available for galcanezumab with historical treatment options. RECENT FINDINGS:Migraine is a common headache disorder and constitutes a significant source of distress from both a personal and societal perspective. Conventional treatment includes abortive and preventive treatment. Treatment options are limited and may be only partially or minimally effective in some of the population. Recent evidence points to metabolic changes in the brain as possible causes of migraine, via reduced available energy or a spiking need for it, resulting in a relative insufficiency. This leads to trigeminocervical complex (TCC) activation and a headache episode, modulated by calcitonin gene-related peptide (CGRP). Galcanezumab (Emgality) is a monoclonal antibody targeting CGRP that is given in a monthly injection for the prevention of migraines. Its safety was previously shown in phase 1 and 2 trials, and recent phase 3 trials showed efficacy, with up to 50% reduction in monthly migraine days and improved functional capacity in migraineurs. Studies show that the drug is well tolerated and safe. Migraine headache is a common neurological syndrome that causes great pain and suffering. Treatment options today are limited. Galcanezumab does not prevent migraines, but it is effective in decreasing their frequency and length. It is also much better tolerated than the currently existing therapies. While it is unlikely to provide monotherapy for migraines, it is a novel therapy that may be added for cases of severe or frequent migraines.

Project description:ImportanceMigraine is a disabling neurological disease characterized by severe headache attacks. Treatment options reduce migraine frequency for many patients, but adverse effects lead to discontinuation in many patients.ObjectiveTo demonstrate that galcanezumab is superior to placebo in the prevention of episodic migraine with or without aura.Design, setting, and participantsThe EVOLVE-1 (Evaluation of LY2951742 in the Prevention of Episodic Migraine 1) trial was a double-blind, randomized, placebo-controlled (January 11, 2016, to March 22, 2017) trial comparing galcanezumab (120 mg and 240 mg) vs placebo. Patients received treatments once monthly for 6 months (subcutaneous injection via prefilled syringe) and were followed up for 5 months after their last injection. It was a multicenter, clinic-based study involving 90 sites in North America. Participants in the study were adults (aged 18 to 65 years) with at least a 1-year history of migraine, 4 to 14 migraine headache days per month and a mean of at least 2 migraine attacks per month within the past 3 months, and were diagnosed prior to age 50 years. During the study, no other preventive medications were allowed. A total of 1671 patients were assessed; 809 did not meet study entry or baseline criteria, and 858 were included in the intent-to-treat population.InterventionsPatients were randomized (2:1:1) to monthly placebo, galcanezumab, 120 mg, and galcanezumab, 240 mg.Main outcomes and measuresThe primary outcome was overall mean change from baseline in the number of monthly migraine headache days during the treatment period. Secondary measures included at least 50%, at least 75%, and 100% reduction in monthly migraine headache days, migraine headache days with acute medication use, and scores from the Migraine-Specific Quality of Life questionnaire, Patient Global Impression of Severity, and Migraine Disability Assessment. Treatment-emergent adverse events and serious adverse events were reported.ResultsOf the 1671 patients assessed, 858 (mean age, 40.7 years; 718 women [83.7%]) met study entry criteria and received at least 1 dose of investigational product. The primary objective was met for both galcanezumab doses; treatment with galcanezumab significantly reduced monthly migraine headache days (both P < .001) by 4.7 days (120 mg) and 4.6 days (240 mg) compared with placebo (2.8 days). All key secondary objectives were also significant after multiplicity adjustment. There were no meaningful differences between 120-mg and 240-mg doses of galcanezumab on measures of efficacy. Completion rate during treatment was high (81.9%; n = 718), and the incidence of discontinuation owing to adverse events was less than 5% across all treatment groups.Conclusions and relevanceGalcanezumab 120-mg and 240-mg monthly injections provided clinical benefits and improved functioning. The incidence rate of adverse events was low, demonstrating the favorable tolerability profile of galcanezumab.Trial registrationClinicalTrials.gov Identifier: NCT02614183.

Project description:ObjectiveRimegepant is an orally administered small-molecule calcitonin gene-related peptide (CGRP) receptor antagonist, with demonstrated efficacy in the acute treatment of migraine. Recent estimates from a single-arm trial (BHV3000-201) have also shown evidence of long-term preventive effects in monthly migraine days (MMDs) and health-related quality of life (HRQoL). This study aimed to compare MMDs and HRQoL data for oral rimegepant to those obtained in placebo-controlled trials for injectable anti-CGRP monoclonal antibodies (mAbs) galcanezumab and erenumab.MethodsMatching-adjusted indirect comparisons (MAICs) were conducted using rimegepant subject-level data and published aggregate-level results from mAb trials. Rimegepant baseline characteristics were matched to the pooled subject characteristics from EVOLVE-I/II (galcanezumab vs. placebo; n = 1773) and STRIVE (ereumab vs. placebo; n = 955) by reweighting the rimegepant subjects to more closely match the distributions observed in these trials. To align with inclusion criteria of the mAb trials, only the subset of rimegepant subjects with a history of 4-14 MMDs were included (n = 257). Weighted mean differences were used to calculate adjusted change in MMDs, Migraine Disability Assessment Test (MIDAS) score, and Migraine-Specific Quality of Life Questionnaire version 2 (MSQv2) scores from baseline to week 12.ResultsWhen matched to the EVOLVE trials, rimegepant was superior to placebo with a mean difference in MMD change from baseline [95% confidence interval] of -1.16 [-1.80, -0.52] and was not statistically significantly different from galcanezumab 0.59 [-0.13, 1.32]. When matched to the STRIVE trial, rimegepant was superior to placebo -1.59 [-2.15, -1.03] and was not statistically significantly different from erenumab -0.06 [-0.61, 0.50]. Rimegepant showed superior MIDAS and MSQv2 results compared with placebo in both EVOLVE trials and in the STRIVE trial, no statistically significant differences from galcanezumab and erenumab regarding MIDAS, and favorable results compared with erenumab across all MSQv2 domains, while being generally similar to galcanezumab across all MSQv2 domains.ConclusionsWhen adjustments were made to reflect baseline characteristics in published literature, supporting data from BHV3000-201 suggest that rimegepant every other day is an effective therapy in reducing disability and MMDs and enhancing migraine-specific HRQoL. These data support the preventive benefit observed in randomized trials of rimegepant and further validate its efficacy for both acute and preventive treatment of migraine.

Project description:ImportanceGalcanezumab (LY2951742), a monoclonal antibody against calcitonin gene-related peptide (CGRP), is one of a novel class of new medicines for migraine prevention.ObjectiveTo assess whether at least 1 dose of galcanezumab was superior to placebo for episodic migraine prevention.Design, setting, and participantsA randomized clinical trial was conducted in the United States (July 7, 2014, to August 19, 2015) in clinics of 37 licensed physicians with a specialty including, but not limited to, psychiatry, neurology, internal medicine, and primary care. Subcutaneous injections of galcanezumab, 5, 50, 120, or 300 mg, or placebo were given monthly during the 3-month treatment period. A total of 936 patients were assessed; 526 did not meet study entry or baseline criteria and 410 patients were randomly assigned to receive placebo or galcanezumab. Analyses were conducted on an intent-to-treat population, which included all patients who were randomized and received at least 1 dose of study drug.InterventionsShort-term migraine treatments were allowed as needed except for opioids or barbiturates.Main outcomes and measuresTo determine if at least 1 of the 4 doses of galcanezumab tested was superior to placebo for migraine prevention measured by the mean change from baseline in the number of migraine headache days 9 weeks to 12 weeks after randomization.ResultsOf the 936 patients assessed, 410 met entry criteria (aged 18-65 years with 4-14 migraine headache days per month and migraine onset prior to age 50 years) and were randomized to receive placebo or galcanezumab. For the primary end point, galcanezumab, 120 mg, significantly reduced migraine headache days compared with placebo (99.6% posterior probability -4.8 days; 90% BCI, -5.4 to -4.2 days vs 95% superiority threshold [Bayesian analysis] -3.7 days; 90% BCI, -4.1 to -3.2 days). Adverse events reported by 5% or more of patients in at least 1 galcanezumab dose group and more frequently than placebo included injection-site pain, upper respiratory tract infection, nasopharyngitis, dysmenorrhea, and nausea.Conclusions and relevanceMonthly subcutaneous injections of galcanezumab, both 120 mg and 300 mg, demonstrated efficacy (repeated-measures analysis) for the preventive treatment of migraine and support further development in larger phase 3 studies. All dosages were safe and well tolerated for the preventive treatment of episodic migraine.Trial registrationclinicaltrials.gov Identifier: NCT02163993.

Project description:OBJECTIVE:To evaluate onset of effect of galcanezumab in patients with episodic migraine. BACKGROUND:Galcanezumab is a monoclonal antibody that binds to calcitonin gene-related peptide and is indicated for preventive treatment of migraine. DESIGN/METHODS:Data on the primary outcome measure were analyzed from 2 previously published double-blind, Phase 3 studies (EVOLVE-1 [N = 858] and EVOLVE-2 [N = 915]) wherein adult patients with episodic migraine were randomized to receive monthly subcutaneous injections of galcanezumab 120 mg (with 240-mg loading dose) or 240 mg or placebo for up to 6 months. Monthly onset of effect was defined as the earliest month at which galcanezumab achieved and subsequently maintained statistical superiority to placebo on the mean change from baseline in the number of monthly migraine headache days (MHDs). If onset occurred in Month 1, weekly onset was evaluated and defined as the earliest week at which galcanezumab statistically separated from placebo and maintained statistical separation for remaining weeks in that month. Day of onset of effect was also analyzed, as were monthly and weekly onset, for occurrence of ?50% reduction from baseline in number of MHDs. RESULTS:For both studies, change from baseline in monthly MHDs showed a statistically significant separation of galcanezumab from placebo at Month 1 and each subsequent month (each P < .001). Analysis of the first month for both studies indicated onset of effect in the first week, with galcanezumab-treated patients having significantly higher odds of having fewer MHDs in the first week (odds ratio [95% confidence interval] for EVOLVE-1, 2.71 [2.00, 3.66], and for EVOLVE-2, 2.88 [2.16, 3.86]; both P < .001) and each subsequent week compared with placebo-treated patients (P ? .004). Daily analysis showed onset of effect at Day 1 (first day after injection day). Galcanezumab also demonstrated superiority to placebo on occurrence of ?50% reduction in MHDs starting at Week 1 (percentage of patients with 50% response in galcanezumab group vs placebo group for EVOLVE-1, 54.3% vs 32.4% [P < .001], and for EVOLVE-2, 59.4% vs 38.0% [P < .001]). CONCLUSION:Rapid onset of preventive effect on the first day after injection of galcanezumab was confirmed in both studies of episodic migraine.

Project description:ObjectiveAtogepant is a newly approved medication for the prevention of migraine. This review aims to discuss the efficacy, safety, cost, and place in therapy of atogepant.MethodsThe authors performed a systematic search for sources, including articles, abstracts, and poster presentations. Queried databases were the National Institute of Health, US National Library of Medicine Clinical Trials, PubMed, European PMC, and the Cochrane Library. Search terms included atogepant, QULIPTA™, AGN-241689, MK-803, and N02CD07. Full-text, English language, randomized-controlled trials from 1 February 2012 to 1 February 2022 were included in the review. Additional relevant prescribing information, abstracts, and articles identified through the search were considered for inclusion in this review. A total of 193 database entries were evaluated for inclusion in this narrative review. Three articles representing two randomized controlled trials were reviewed.Results and conclusionsAtogepant, a small-molecule calcitonin gene-related peptide (CGRP) receptor antagonist, is a daily oral treatment for migraine prevention. In placebo-controlled clinical trials, atogepant decreased mean monthly migraine days (MMD) over 12 weeks in patients with episodic migraine. Major treatment-related adverse effects include nausea and constipation. Long-term placebo-controlled efficacy and safety studies, chronic migraine studies, and studies in patients that failed more than two classes of preventive therapies are still pending. Atogepant represents one of many novel therapies for the prevention of migraine. To date, no head-to-head comparisons of atogepant versus other agents indicated for migraine prevention have been published. Atogepant offers patients an alternative therapy to injectable or infusion monoclonal antibody treatments and offers an alternative to non-specific migraine medications that are associated with poor tolerability. Due to its high cost and narrower therapeutic indications, atogepant may be reserved for a small subset of migraineurs who prefer oral therapy.
