ABSTRACT:

Objective

Atogepant 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.

Methods

The 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 conclusions

Atogepant, 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.

Project description:IntroductionThe inhibition of the calcitonin gene-related peptide (CGRP) pathway has attracted interest in pharmacological research on migraine. Atogepant is a potent, selective, orally available antagonist of the CGRP receptor approved as a preventive treatment of episodic migraine. This systematic review with meta-analysis aims to evaluate the efficacy and safety of atogepant for the prevention of episodic migraine in adult patients.MethodsRandomized, placebo-controlled, single or double-blinded trials were identified through a systematic literature search (December week 4, 2021). Main outcomes included the changes from baseline in monthly migraine days and the incidence of adverse events (AEs) and treatment withdrawal due to AEs. Mean difference (MD) and risk ratio (RR) with 95% confidence intervals (95% CIs) were estimated.ResultsTwo trials were included, overall enrolling 1550 patients. A total of 408 participants were randomized to placebo, 314 to atogepant 10 mg, 411 to atogepant 30 mg, and 417 to atogepant 60 mg once daily. The mean age of the patients was 41.0 years and 87.7% were women. The reduction in the mean number of migraine days from baseline across the 12-week treatment period was significantly greater among patients treated with atogepant at either the daily dose of 10 mg (MD - 1.16, 95% CI - 1.60 to - 0.73, p < 0.001), 30 mg (MD - 1.15, 95% CI - 1.54 to - 0.76, p < 0.001), or 60 mg (MD - 1.20, 95% CI - 2.18 to - 0.22, p = 0.016) than with placebo. There were no differences in the occurrence of AEs and drug withdrawal due to AEs between atogepant and placebo groups. Constipation was more commonly observed in patients treated with atogepant at 30 mg/day than placebo (RR 5.19, 95% CI 2.00-13.46; p = 0.001). Treatment with atogepant at the daily dose of 60 mg was associated with a higher risk of constipation (RR 4.92, 95% CI 1.89-12.79; p = 0.001) and nausea (RR 2.73, 95% CI 1.47-5.06; p = 0.001) than placebo.ConclusionAtogepant is an efficacious and overall well-tolerated treatment for the prevention of episodic migraine in adults.

Project description:BackgroundMigraine is a neurological condition marked by frequent headaches, which tends to be accompanied by nausea and vomiting in severe instances. Injectable therapies for migraine, such as monoclonal antibodies that target calcitonin gene-related peptide (CGRP), have proven to be effective and safe. While various oral drugs are available, none have been developed for migraines. Patients prefer oral therapies because they are easier to use, making atogepant, an orally accessible small-molecule CGRP receptor antagonist, a possible alternative.ObjectivesThis systematic review and meta-analysis compared the safety and effectiveness of atogepant with placebo in treating migraine.MethodsAdhering to the PRISMA guidelines, we meticulously gathered randomized controlled trials (RCTs) from databases including the Cochrane Library, PubMed, Science Direct, and ClinicalTrials.gov. Studies comparing atogepant with placebo and reporting monthly migraine days (MMDs) as the primary outcome along with secondary outcomes such as monthly headache days and acute medication use days were included. Two independent reviewers conducted the data extraction and quality assessment. Statistical analyses were carried out using RevMan, utilizing risk ratios for dichotomous outcomes and mean differences for continuous outcomes, and a random-effects model.ResultsOur primary outcome was the change in MMDs over 12 weeks, which showed a significant reduction with atogepant at dosages of 10, 30, and 60 mg. Secondary outcomes, such as monthly headache days, proportion of patients achieving a ≥ 50% reduction in MMDs, acute medication use days, and patient-reported outcomes, consistently showed that atogepant outperformed placebo, highlighting its effectiveness in reducing the migraine burden.ConclusionHigher doses of atogepant are more effective in lowering migraine and headache-related days and increasing quality of life metrics. However, this is accompanied by an increased incidence of adverse events, suggesting the need for careful dose optimization to balance the benefits and risks.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=563395.

Project description:OBJECTIVE:A phase 2, double-blind, placebo-controlled study to evaluate the efficacy and safety of erenumab for the prevention of episodic migraine in Japanese patients was conducted. BACKGROUND:Previous global clinical studies have demonstrated the efficacy of erenumab in the prevention of migraine. METHODS:Patients were randomized to placebo or erenumab 28, 70, or 140 mg administered subcutaneously once per month for 6 months. The primary endpoint was change from baseline in mean monthly migraine days over months 4-6 of the double-blind treatment phase. Secondary endpoints included the proportion of patients achieving ≥50% reduction from baseline in mean monthly migraine days (≥50% response) and change from baseline in mean monthly acute migraine-specific medication treatment days (MSMD) and mean Headache Impact Test (HIT-6™) scores. Efficacy outcomes were also determined at months 1, 2, and 3. RESULTS:Four hundred and seventy five patients were randomized 2:1:2:2 to placebo and erenumab 28, 70, and 140 mg, respectively. Greater reductions in monthly migraine days were observed for erenumab vs placebo with differences of -1.25 (95% CI: -2.10 to -0.41; P = .004), -2.31 (95% CI: -3.00 to -1.62; P < .001), and -1.89 (95% CI: -2.58 to -1.20; P < .001) days for erenumab 28, 70, and 140 mg. The odds of having a ≥50% response were 3.2, 5.6, and 4.7 times greater for erenumab 28 mg (95% CI: 1.30-7.88; P = .009), 70 mg (95% CI: 2.60-12.06; P < .001), and 140 mg (95% CI: 2.24-9.99; P < .001) than for placebo. Greater reductions from baseline in mean acute monthly MSMD were observed for erenumab vs placebo with differences of -1.07 (95% CI: -1.80 to -0.35; P = .004), -2.07 (95% CI: -2.66 to -1.49; P < .001), and -2.04 (95% CI: -2.63 to -1.45; P < .001) days for erenumab 28, 70, and 140 mg. Erenumab 70 and 140 mg also resulted in greater improvements in HIT-6™ scores. The safety profile was similar across treatment groups. The most common adverse event was nasopharyngitis, which occurred in 29.4% of patients in the placebo group and 28.9%-33.3% of patients in the erenumab groups. CONCLUSION:Monthly subcutaneous injections of erenumab 70 mg demonstrated statistically significant and numerically maximal efficacy with a favorable safety profile, suggesting that erenumab is a potential new therapy for migraine prevention in Japan.

Project description:ObjectivesSystematic review of preventive pharmacologic treatments for community-dwelling adults with episodic migraine.Data sourcesElectronic databases through May 20, 2012.Eligibility criteriaEnglish-language randomized controlled trials (RCTs) of preventive drugs compared to placebo or active treatments examining rates of ?50 % reduction in monthly migraine frequency or improvement in quality of life.Study appraisal and synthesis methodsWe assessed risk of bias and strength of evidence and conducted random effects meta-analyses of absolute risk differences and Bayesian network meta-analysis.ResultsOf 5,244 retrieved references, 215 publications of RCTs provided mostly low-strength evidence because of the risk of bias and imprecision. RCTs examined 59 drugs from 14 drug classes. All approved drugs, including topiramate (9 RCTs), divalproex (3 RCTs), timolol (3 RCTs), and propranolol (4 RCTs); off-label beta blockers metoprolol (4 RCTs), atenolol (1 RCT), nadolol (1 RCT), and acebutolol (1 RCT); angiotensin-converting enzyme inhibitors captopril (1 RCT) and lisinopril (1 RCT); and angiotensin II receptor blocker candesartan (1 RCT), outperformed placebo in reducing monthly migraine frequency by ?50 % in 200-400 patients per 1,000 treated. Adverse effects leading to treatment discontinuation (68 RCTs) were greater with topiramate, off-label antiepileptics, and antidepressants than with placebo. Limited direct evidence as well as frequentist and exploratory network Bayesian meta-analysis showed no statistically significant differences in benefits between approved drugs. Off-label angiotensin-inhibiting drugs and beta-blockers were most effective and tolerable for episodic migraine prevention.LimitationsWe did not quantify reporting bias or contact principal investigators regarding unpublished trials.ConclusionsApproved drugs prevented episodic migraine frequency by ?50 % with no statistically significant difference between them. Exploratory network meta-analysis suggested that off-label angiotensin-inhibiting drugs and beta-blockers had favorable benefit-to-harm ratios. Evidence is lacking for long-term effects of drug treatments (i.e., trials of more than 3 months duration), especially for quality of life.

Project description:ImportanceSome patients with migraine, particularly those in primary care, require effective, well-tolerated, migraine-specific oral preventive treatments.ObjectiveTo examine the efficacy of atogepant, an oral, small-molecule, calcitonin gene-related peptide receptor antagonist, using 4 levels of mean monthly migraine-day (MMD) responder rates.Design, setting, and participantsThis secondary analysis of a phase 3, double-blind, placebo-controlled randomized clinical trial evaluated the efficacy and safety of atogepant for the preventive treatment of migraine from December 14, 2018, to June 19, 2020, in adults with 4 to 14 migraine-days per month at 128 sites in the US.InterventionsPatients were administered 10 mg of atogepant (n = 222), 30 mg of atogepant (n = 230), 60 mg of atogepant (n = 235), or placebo (n = 223) once daily in a 1:1:1:1 ratio for 12 weeks.Main outcomes and measuresThese analyses evaluated treatment responder rates, defined as participants achieving 50% or greater (α-controlled, secondary end point) and 25% or greater, 75% or greater, and 100% (prespecified additional end points) reductions in mean MMDs during the 12-week blinded treatment period.ResultsOf 902 participants (mean [SD] age, 41.6 [12.3] years; 801 [88.8%] female; 752 [83.4%] White; 825 [91.5%] non-Hispanic), 873 were included in the modified intention-to-treat population (placebo, 214; 10 mg of atogepant, 214; 30 mg of atogepant, 223; and 60 mg of atogepant, 222). For the secondary end point, a 50% or greater reduction in the 12-week mean of MMDs was achieved by 119 of 214 participants (55.6%) treated with 10 mg of atogepant (odds ratio, 3.1; 95% CI, 2.1-4.6), 131 of 223 participants (58.7%) treated with 30 mg atogepant (odds ratio, 3.5; 95% CI, 2.4-5.3), 135 of 222 participants (60.8%) treated with 60 mg of atogepant (odds ratio, 3.8; 95% CI, 2.6-5.7), and 62 of 214 participants (29.0%) given placebo (P < .001). The numbers of participants who reported a 25% or greater reduction in the 12-week mean of MMDs were 157 of 214 (73.4%) for 10 mg of atogepant, 172 of 223 (77.1%) for 30 mg of atogepant, and 180 of 222 (81.1%) for 60 mg of atogepant vs 126 of 214 (58.9%) for placebo (P < .002). The numbers of participants who reported a 75% or greater reduction in mean MMDs were 65 of 214 (30.4%) for 10 mg of atogepant, 66 of 223 (29.6%) for 30 mg of atogepant, and 84 of 222 (37.8%) for 60 mg of atogepant compared with 23 of 214 (10.7%) for placebo (P < .001). The numbers of participants reporting 100% reduction in mean MMDs were 17 of 214 (7.9%) for 10 mg of atogepant (P = .004), 11 of 223 (4.9%) for 30 mg of atogepant (P = .02), and 17 of 222 (7.7%) for 60 mg of atogepant (P = .003) compared with 2 of 214 (0.9%) for placebo.Conclusions and relevanceAt all doses, atogepant was effective during the 12-week double-blind treatment period beginning in the first 4 weeks, as evidenced by significant reductions in mean MMDs at every responder threshold level. Higher atogepant doses appeared to produce the greatest responder rates, which can guide clinicians in individualizing starting doses.Trial registrationClinicalTrials.gov Identifier: NCT03777059.

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: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.
