Effect of Different Doses of Galcanezumab vs Placebo for Episodic Migraine Prevention: A Randomized Clinical Trial.

ABSTRACT:

Importance

Galcanezumab (LY2951742), a monoclonal antibody against calcitonin gene-related peptide (CGRP), is one of a novel class of new medicines for migraine prevention.

Objective

To assess whether at least 1 dose of galcanezumab was superior to placebo for episodic migraine prevention.

Design, setting, and participants

A 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.

Interventions

Short-term migraine treatments were allowed as needed except for opioids or barbiturates.

Main outcomes and measures

To 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.

Results

Of 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 relevance

Monthly 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.

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:BACKGROUND:Galcanezumab is a novel monoclonal antibody that target to calcitonin gene-related peptide (CGRP). It has been tested for the preventive treatment of migraine and episodic cluster headache by multiple randomized clinical trials (RCTs) and have been found to reduce headache frequency. METHODS:We systematically searched PubMed and Embase on Cochrane Central Register of Controlled Trials (CENTRAL) from the earliest date to August 1, 2019. Relative risk (RR) and weighted mean difference (WMD) were used to evaluate clinical outcomes. RESULTS:Seven studies were pooled with 3889 patients. Subcutaneous injection of Galcanezumab at 120?mg, 240?mg leads to a statistically significant response rate for the treatment of migraine compared with placebo (120?mg: RR?=?1.51; 95% CI, 1.33 to 1.70; P?<?0.001; 240?mg: RR?=?1.58; 95% CI, 1.43 to 1.76; P?<?0.001). Among them, 120?mg group has the same treatment efficacy with 240?mg group (50% response: RR?=?1.06; 95% CI, 0.92 to 1.22; P?=?0.425; 75% response: RR?=?1.07; 95% CI, 0.94 to 1.23; P?=?0.301; 100% response; RR?=?1.06; 95% CI, 0.81 to 1.37; P?=?0.682; MHD: RR?=?-?0.08; 95% CI, -?0.55 to -?0.40; P?=?0.748) while related to a lower risk for adverse events for the treatment of migraine (120?mg RR?=?1.06; 95% CI, 0.99 to 1.14; P?=?0.084; 240?mg: RR?=?1.17; 95% CI, 1.09 to 1.25; P?<?0.001). 300?mg per month galcanezumab is effective for the prevention of episodic cluster headache measured by at least 50% reduction of cluster headache frequency at week 3 (RR?=?1.36; 95% CI, 1.00-1.84; P?=?0.048). CONCLUSIONS:Use of galcanezumab is related to a significantly reduced monthly headache frequency compared with placebo for the treatment of migraine and episodic cluster headache, 120?mg has the same treatment efficacy with 240?mg group while related to a lower risk for adverse effects for the treatment of migraine. 300?mg per month galcanezumab is effective for the prevention of episodic cluster headache with no significantly increased adverse events.

Project description:ImportanceFremanezumab, a fully humanized monoclonal antibody that targets calcitonin gene-related peptide, may be effective for treating episodic migraine.ObjectiveTo assess the efficacy of fremanezumab compared with placebo for prevention of episodic migraine with a monthly dosing regimen or a single higher dose.Design and settingRandomized, double-blind, placebo-controlled, parallel-group trial conducted at 123 sites in 9 countries from March 23, 2016 (first patient randomized), to April 10, 2017, consisting of a screening visit, 28-day pretreatment period, 12-week treatment period, and final evaluation at week 12.ParticipantsStudy participants were aged 18 to 70 years with episodic migraine (6-14 headache days, with at least 4 migraine days, during 28-day pretreatment period). Patients who had previous treatment failure with 2 classes of migraine-preventive medication were excluded.InterventionsPatients were randomized 1:1:1 to receive subcutaneous monthly dosing of fremanezumab (n = 290; 225 mg at baseline, week 4, and week 8); a single higher dose of fremanezumab, as intended to support a quarterly dose regimen (n = 291; 675 mg of fremanezumab at baseline; placebo at weeks 4 and 8); or placebo (n = 294; at baseline, week 4, and week 8).Main outcomes and measuresThe primary end point was mean change in mean number of monthly migraine days during the 12-week period after the first dose.ResultsAmong 875 patients who were randomized (mean age, 41.8 [SD, 12.1] years; 742 women [85%]), 791 (90.4%) completed the trial. From baseline to 12 weeks, mean migraine days per month decreased from 8.9 days to 4.9 days in the fremanezumab monthly dosing group, from 9.2 days to 5.3 days in the fremanezumab single-higher-dose group, and from 9.1 days to 6.5 days in the placebo group. This resulted in a difference with monthly dosing vs placebo of -1.5 days (95% CI, -2.01 to -0.93 days; P < .001) and with single higher dosing vs placebo of -1.3 days (95% CI, -1.79 to -0.72 days; P < .001). The most common adverse events that led to discontinuation were injection site erythema (n = 3), injection site induration (n = 2), diarrhea (n = 2), anxiety (n = 2), and depression (n = 2).Conclusions and relevanceAmong patients with episodic migraine in whom multiple medication classes had not previously failed, subcutaneous fremanezumab, compared with placebo, resulted in a statistically significant 1.3- to 1.5-day reduction in the mean number of monthly migraine days over a 12-week period. Further research is needed to assess effectiveness against other preventive medications and in patients in whom multiple preventive drug classes have failed and to determine long-term safety and efficacy.Trial registrationclinicaltrials.gov Identifier: NCT02629861.

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:PurposeThis study aimed to extensively evaluate the onset and maintenance effect of galcanezumab compared with placebo for the prevention of episodic migraine in Japanese patients.Patients and methodsThis was a post-hoc analysis of a Phase 2, multicenter, randomized, double-blind, placebo-controlled study conducted between December 2016 and January 2019 (ClinicalTrials.gov: NCT02959177). Patients aged between 18 and 65 years with episodic migraine were randomized to receive a monthly injection of galcanezumab (120 mg: N = 115, 240 mg: N = 114) or placebo (N = 230) for 6 months. Outcome measures included onset of effect at weekly and daily intervals-assessed by change from baseline in the number of migraine headache days and the proportion of patients with migraine headache-with galcanezumab versus placebo. To further confirm the onset and maintenance effect, the 50% response rate was also evaluated.ResultsThe mean change from baseline in weekly migraine headache days was significantly reduced with galcanezumab (-0.97 days) compared with placebo (-0.10 days) at week 1 (p ≤ 0.0001), which was maintained at all subsequent weeks up to week 4 (all p ≤ 0.0001 vs placebo). A significantly smaller proportion of galcanezumab-treated patients had migraine headache compared with placebo-treated patients at day 1 after the first injection (13.6% vs 31.4%, respectively; p ≤ 0.0001), which was also maintained at all subsequent days during the first week after the first injection. Furthermore, the 50% response rate was significantly higher with galcanezumab compared with placebo from week 1 through month 6.ConclusionThe onset of the migraine preventive effect of galcanezumab was rapid compared with placebo, starting from day 1 after the first injection in Japanese patients with episodic migraine. The effect was maintained during the first week and first month, and throughout 6 months of monthly injections of galcanezumab. Galcanezumab is a promising preventive treatment in Japanese patients with episodic migraine.

Project description:IntroductionThere have been no prior trials directly comparing the efficacy of different calcitonin gene-related peptide (CGRP) antagonists for migraine prevention. Reported are the results from the first head-to-head study of two CGRP antagonists, galcanezumab (monoclonal antibody) versus rimegepant (gepant), for the prevention of episodic migraine.MethodsIn this 3-month, double-blind, double-dummy study, participants were randomized (1:1) to subcutaneous (SC) galcanezumab 120 mg per month (after a 240 mg loading dose) and a placebo oral disintegrating tablet (ODT) every other day (q.o.d.) or to rimegepant 75 mg ODT q.o.d. and a monthly SC placebo. The primary endpoint was the proportion of participants with a ≥ 50% reduction in migraine headache days per month from baseline across the 3-month double-blind treatment period. Key secondary endpoints were overall mean change from baseline in: migraine headache days per month across 3 months and at month 3, 2, and 1; migraine headache days per month with acute migraine medication use; Migraine-Specific Quality of Life Questionnaire Role Function-Restrictive domain score at month 3; and a ≥ 75% and 100% reduction from baseline in migraine headache days per month across 3 months.ResultsOf 580 randomized participants (galcanezumab: 287, rimegepant: 293; mean age: 42 years), 83% were female and 81% Caucasian. Galcanezumab was not superior to rimegepant in achieving a ≥ 50% reduction from baseline in migraine headache days per month (62% versus 61% respectively; P = 0.70). Given the pre-specified multiple testing procedure, key secondary endpoints cannot be considered statistically significant. Overall, treatment-emergent adverse events were reported by 21% of participants, with no significant differences between study intervention groups.ConclusionsGalcanezumab was not superior to rimegepant for the primary endpoint; however, both interventions demonstrated efficacy as preventive treatments in participants with episodic migraine. The efficacy and safety profiles observed in galcanezumab-treated participants were consistent with previous studies.Trial registrationClinTrials.gov-NCT05127486 (I5Q-MC-CGBD).

Project description:ObjectiveTo evaluate the efficacy and safety of galcanezumab, a humanized monoclonal antibody that selectively binds to calcitonin gene-related peptide, in the preventive treatment of chronic migraine.MethodsA phase 3, randomized, double-blind, placebo-controlled study of LY2951742 in patients with chronic migraine (Evaluation of Galcanezumab in the Prevention of Chronic Migraine [REGAIN]) was a phase 3 study with a 3-month double-blind, placebo-controlled treatment phase and a 9-month open-label extension. Eligible patients 18 to 65 years of age with chronic migraine were randomized 2:1:1 to monthly subcutaneous injections of placebo (n = 558), galcanezumab 120 mg (with a 240-mg loading dose, n = 278), or galcanezumab 240 mg (n = 277). The primary endpoint was the overall mean change from baseline in the number of monthly migraine headache days (MHDs) during the 3-month double-blind treatment phase.ResultsMean number of monthly MHDs at baseline was 19.4 for the total sample. Both galcanezumab dose groups demonstrated greater overall mean reduction in the number of monthly MHDs compared to placebo (placebo -2.7, galcanezumab 120 mg -4.8, galcanezumab 240 mg -4.6) (p < 0.001 for each dose compared to placebo). There were no clinically meaningful differences between galcanezumab doses and placebo on any safety or tolerability outcome except for a higher incidence of treatment-emergent injection-site reaction (p < 0.01), injection-site erythema (p < 0.001), injection-site pruritus (p < 0.01), and sinusitis (p < 0.05) in the galcanezumab 240-mg group relative to placebo.ConclusionsBoth doses of galcanezumab were superior to placebo in reducing the number of monthly MHDs. Galcanezumab appears efficacious, safe, and well tolerated for the preventive treatment of chronic migraine.Clinicaltrialsgov identifierNCT02614261.Classification of evidenceThis interventional study provides Class I evidence that galcanezumab is superior to placebo in the reduction of the number of monthly MHDs.

Project description:IntroductionThis analysis evaluated the treatment satisfaction of Japanese patients receiving galcanezumab (GMB) as a preventive medication for episodic migraine (4-14 monthly migraine headache days).MethodsThis phase 2, randomized, double-blind, placebo-controlled study enrolled patients aged 18-65 years at 40 centers in Japan. Patients were randomized 2:1:1 to receive monthly subcutaneous injections of placebo (PBO, n = 230), GMB 120 mg (n = 115), or GMB 240 mg (n = 114) for 6 months. Patients' experience with treatment was measured using the Patient Global Impression of Severity (PGI-S), Patient Global Impression of Improvement (PGI-I), and Patient Satisfaction with Medication Questionnaire-Modified (PSMQ-M) scales. PGI-S was administered at baseline and months 1-6, PGI-I at months 1-6, and PSMQ-M at months 1 and 6. Prespecified analyses were differences between GMB and PBO in PGI-I and the change from baseline in PGI-S, and evaluating positive responses for the PGI-I and PSMQ-M.ResultsAverage change ± SE from baseline across months 1-6 was - 0.09 ± 0.05 (PBO), - 0.17 ± 0.07 (GMB 120 mg, p = 0.33), and - 0.30 ± 0.07 (GMB 240 mg, p = 0.013) for PGI-S. Average PGI-I across months 1-6 was 3.39 ± 0.05 (PBO), 2.55 ± 0.07 (GMB 120 mg, p < 0.05), and 2.71 ± 0.07 (GMB 240 mg, p < 0.05). Reductions of 2.8-3.0 monthly migraine headache days corresponded to 25-31% higher positive PGI-I response rates with GMB compared with PBO. Positive PSMQ-M response rates for satisfaction and preference were statistically significantly higher for GMB compared with PBO (odds ratio [95% confidence interval], all p < 0.05 vs. PBO): satisfaction GMB 120 mg (3.142 [1.936-5.098]) and GMB 240 mg (3.924 [2.417-6.369]), and preference GMB 120 mg (3.691 [2.265-6.017]) and GMB 240 mg (3.510 [2.180-5.652]).ConclusionJapanese patients with episodic migraine receiving preventive treatment with GMB are significantly more satisfied than those receiving PBO.Trial registrationClinicalTrials.gov, NCT02959177 (registered November 7, 2016).

Project description:BackgroundGalcanezumab, a humanized monoclonal antibody that binds calcitonin gene-related peptide, has demonstrated a significant reduction in monthly migraine headache days compared with placebo. Here, we analyze data from 3 randomized clinical trials (2 episodic trials [EVOLVE-1, EVOLVE-2] and 1 chronic trial [REGAIN]), to examine if galcanezumab also alleviates the severity and symptoms of migraine.MethodsThe episodic migraine trials were 6-month, double-blind studies in patients with episodic migraine (4-14 monthly migraine headache days). The chronic migraine trial was a 3-month, double-blind study in patients with chronic migraine (≥ 15 headache days per month, where ≥ 8 met criteria for migraine). Patients (18-65 years) were randomized to placebo or galcanezumab 120 mg with a 240-mg loading dose or 240 mg. Patients recorded headache characteristics, duration, severity, and presence of associated symptoms with each headache. The outcomes analyzed were changes from baseline in number of monthly migraine headache days with nausea and/or vomiting, photophobia and phonophobia, aura, and prodromal symptoms other than aura. Additional outcomes analyzed included the number of moderate-to-severe monthly migraine headache days, number of severe migraine headache days, and mean severity of remaining migraine headache days. Change from baseline in the proportion of days with nausea and/or vomiting and the proportion of days with photophobia and phonophobia among the remaining monthly migraine headache days were also analyzed.ResultsGalcanezumab was superior to placebo in reducing the frequency of migraine headache days with associated symptoms of migraine such as nausea and/or vomiting, photophobia and phonophobia, and prodromal symptoms. Galcanezumab reduced the frequency of migraine headache days with aura in the episodic migraine studies. There was a significant reduction in the proportion of remaining migraine headache days with nausea and/or vomiting for the episodic and chronic migraine studies, and with photophobia and phonophobia for the episodic migraine studies. Galcanezumab was superior to placebo in reducing the number of monthly moderate-to-severe migraine headache days and the overall and monthly severe migraine headache days.ConclusionsGalcanezumab reduces the frequency of migraine headache days and can alleviate potentially disabling non-pain symptoms on days when migraine is present in patients with episodic or chronic migraine.Trial registrationNCT, NCT02614183 (EVOLVE-1), registered 25 November 2015; NCT, NCT02614196 , (EVOLVE-2), registered 25 November 2015; NCT, NCT02614261 (REGAIN), registered 25 November 2015.
