RESUMEN

BACKGROUND: The present study evaluated the long-term safety and tolerability of rimegepant, an orally administered small molecule calcitonin gene-related peptide receptor antagonist, in people with migraine. METHODS: This multicenter, long-term, open-label safety study included adults (≥18 years) with ≥1 year history of migraine who were sequentially enrolled into three groups: participants in the first two groups had either 2-8 or 9-14 moderate to severe migraine attacks per month by history and treated as needed (pro re nata [PRN]) with one rimegepant 75 mg oral tablet up to once per calendar day for 52 weeks (PRN 2-8 and PRN 9-14); a third group, included to collect safety data during higher-frequency dosing, had 4-14 moderate to severe migraine attacks per month by history and who took one rimegepant tablet every other day as scheduled dosing plus PRN dosing of one rimegepant tablet for migraine attacks of any severity on nonscheduled dosing days for 12 weeks (every other day (EOD) + PRN). RESULTS: Overall, 1800 participants self-administered rimegepant (PRN 2-8: n = 1033; PRN 9-14: n = 481; EOD + PRN: n = 286). The most common on-treatment adverse events (AEs) were upper respiratory tract infection (8.8%), nasopharyngitis (6.8%) and sinusitis (5.1%). Most AEs were mild or moderate and considered unrelated to rimegepant. Serious AEs considered possibly (n = 1) or unlikely (n = 9) related to rimegepant were reported in ten (0.6%) participants. No signal of drug-induced liver injury because of rimegepant was identified. CONCLUSIONS: Rimegepant 75 mg up to once per day as EOD + PRN for 12 weeks or PRN for up to 52 weeks was safe and well tolerated. No signal of hepatotoxicity, potential drug abuse, or medication-overuse headache was identified.Trial registration: Clinicaltrials.gov: NCT03266588.

RESUMEN

OBJECTIVE: This post hoc analysis of the PREVAIL study explored the effectiveness of eptinezumab for up to 2 years of open-label treatment in the subgroup of patients with chronic migraine who had a confirmed diagnosis of medication-overuse headache (MOH) at screening. BACKGROUND: MOH is a disabling and costly secondary headache disorder characterized by increased headache frequency and/or severity with increased acute headache medication use. Eptinezumab, an anti-calcitonin gene-related peptide monoclonal antibody, reduces headache frequency, severity, and associated disability and improves functioning and health-related quality of life as a preventive migraine therapy; short-term benefits in patients with concurrent MOH have also been reported. METHODS: Participants received up to eight quarterly intravenous infusions of eptinezumab 300 mg in the phase 3, single-arm, open-label PREVAIL study. Safety and patient-reported outcome measures (Migraine Disability Assessment [MIDAS], 6-item Headache Impact Test [HIT-6], patient-identified most bothersome symptom [PI-MBS], Patient Global Impression of Change [PGIC], and 36-item Short-Form Health Survey [SF-36]) were conducted at predefined intervals. Patients were observed up to 20 weeks after their last infusion (Week 104). RESULTS: A total of 49/128 (38.3%) patients enrolled in PREVAIL had an MOH diagnosis at screening. In the MOH subgroup, long-term eptinezumab treatment was associated with reductions in headache frequency (43/49 [87.8%] patients reported ≥50% reduction in MIDAS-derived headache days at ≥1 visit), severity (2.2-point reduction [on a 10-point scale]), disability (mean MIDAS total score reduction of 51.9 points), and impact (mean HIT-6 total score reduction of 9.7 points) at Week 104. Most patients described a "much improved" or "very much improved" status by Week 48 (PI-MBS, 31/46 [67.4%]) and Week 104 (PGIC, 31/36 [86.1%]). Health-related quality of life improvements in the SF-36 were also observed. CONCLUSION: Eptinezumab preventive therapy in patients with chronic migraine showed benefits that extended to the subset of patients with concomitant MOH.

RESUMEN

OBJECTIVE: To assess cardiovascular (CV) safety of erenumab in clinical trial patients associated with degree of CV risk. BACKGROUND: Hypertension has been considered a theoretical risk associated with the inhibition of the calcitonin gene-related peptide pathway in migraine management, particularly in a patient population with pre-existing CV risk factors. METHODS: Data pooled from four double-blind, randomized trials were used to assess blood pressure (BP) changes and CV safety in patients grouped based on 10-year risk of cardiac, cerebrovascular, and peripheral artery disease as no-risk-factors, low-risk (>0% to ≤10%), moderate-risk (>10% to ≤20%), and high-risk (>20%) categories. CV safety was assessed as ischemic cardiovascular and cerebrovascular adverse events (ICCAE). RESULTS: There was no apparent difference between placebo- (N = 1032) and erenumab-treatment groups (70 mg, N = 885; 140 mg, N = 504) in clinical worsening of BP category from baseline to Months 1-3 (14% [143/1032] placebo vs. 13% [114/885] and 14% [71/504] for erenumab 70 and 140 mg, respectively) regardless of baseline BP category. The adverse event (AE) profile of erenumab was similar across CV risk categories throughout the long-term analysis. Erenumab-treated patients with high and moderate 10-year CV risk (N = 107) did not experience any ICCAEs during the double-blind treatment period; there was a single ICCAE (a cerebral dural venous sinus thrombosis) observed in the low-risk erenumab group (N = 273). There were no increases in AEs during the long-term extensions of up to 5 years (N = 2499; 3482 patient-years of exposure to erenumab) with exposure-adjusted incidence rates of cardio/cerebrovascular disorder AEs of 0.4, 0.5, 0.0, and 1.1 (per 100 patient-years) for no risk factor (N = 1805), low (N = 492), moderate (N = 121), and high (N = 81) 10-year CV risk groups, respectively. CONCLUSIONS: Ischemic CV and cerebrovascular AEs were uncommon and the incidence rates were similar across the 10-year CV risk categories. This analysis helps provide more detail on the CV safety of erenumab.

RESUMEN

OBJECTIVE: Assess the long-term efficacy and safety of erenumab in patients with chronic migraine with acute medication overuse. BACKGROUND: Overuse of acute medication in patients with chronic migraine has been linked to greater pain intensity and disability and may diminish the effectiveness of preventive therapies. METHODS: This 52-week open-label extension study followed a 12-week double-blind placebo-controlled study in which patients with chronic migraine were randomized 3:2:2 to placebo or once-monthly erenumab 70 mg or 140 mg. Patients were stratified by region and medication overuse status. Patients received erenumab 70 mg or 140 mg throughout or switched from erenumab 70 to 140 mg (based on protocol amendment to augment safety data at higher dose). Efficacy was assessed in patients with and without medication overuse at parent study baseline. RESULTS: Of 609 patients enrolled in the extension study, 252/609 (41.4%) met the criteria for medication overuse at parent study baseline. At Week 52, the mean change in monthly migraine days from parent study baseline was -9.3 (95% confidence interval: -10.4, -8.1 days) in the medication overuse subgroup versus -9.3 (-10.1, -8.5 days) in the non-medication overuse subgroup (combined erenumab doses); proportion of patients achieving ≥50% reduction in monthly migraine days at Week 52 was 55.9% (90/161; 48.2%, 63.3%) versus 61.3% (136/222; 54.7%, 67.4%), respectively. Among baseline users of acute migraine-specific medication, the mean change in monthly migraine-specific medication days at Week 52 was -7.4 (-8.3, -6.4 days) in the medication overuse subgroup versus -5.4 (-6.1, -4.7 days) in the non-medication overuse subgroup. Most patients (197/298; 66.1%) in the medication overuse subgroup transitioned to non-overuse status by Week 52. Erenumab 140 mg was associated with numerically greater efficacy than erenumab 70 mg across all endpoints. No new safety signals were identified. CONCLUSION: Long-term erenumab treatment demonstrated sustained efficacy and safety in patients with chronic migraine with and without acute medication overuse.

RESUMEN

BACKGROUND: Rimegepant is a calcitonin gene-related peptide receptor antagonist that has shown efficacy and safety in the acute treatment of migraine. We aimed to compare the efficacy of rimegepant with placebo for preventive treatment of migraine. METHODS: We did a multicentre, phase 2/3, randomised, double-blind, placebo-controlled trial at 92 sites in the USA. Adults with at least a 1-year history of migraine were recruited. After a 4-week observation period, eligible participants were randomised using an interactive web response system to oral rimegepant 75 mg or matching placebo every other day for 12 weeks (double-blind treatment phase). The primary efficacy endpoint was change from the 4-week observation period in the mean number of migraine days per month in the last 4 weeks of the double-blind treatment phase (weeks 9-12). Participants who received at least one dose of their assigned study medication and who had 14 days or more of data in the observation period and 14 days or more of data for at least one 4-week interval during the double-blind treatment phase were analysed for efficacy. Those who received at least one dose of study medication were analysed for safety. This study is registered with ClinicalTrials.gov, NCT03732638. FINDINGS: Between Nov 14, 2018, and Aug 30, 2019, 1591 participants were recruited and assessed for eligibility, of whom 747 were randomly allocated either rimegepant (n=373) or placebo (n=374). 695 participants were included in the analysis for efficacy, of whom 348 were assigned rimegepant and 347 were allocated placebo. Rimegepant was superior to placebo on the primary endpoint of change in the mean number of migraine days per month during weeks 9-12. The change from the observation period in mean number of migraine days per month during weeks 9-12 was -4·3 days (95% CI -4·8 to -3·9) with rimegepant and -3·5 days (-4·0 to -3·0) with placebo (least squares mean difference -0·8 days, 95% CI -1·46 to -0·20; p=0·0099). 741 participants received study medication and were included in the safety analysis. 133 (36%) of 370 patients who received rimegepant reported an adverse event, compared with 133 (36%) of 371 who received placebo. Seven (2%) participants who received rimegepant and four (1%) who received placebo discontinued the study due to an adverse event; no patients died. INTERPRETATION: Taken every other day, rimegepant was effective for preventive treatment of migraine. Tolerability was similar to that of placebo, and no unexpected or serious safety issues were noted. FUNDING: Biohaven Pharmaceuticals.

RESUMEN

OBJECTIVE: To examine changes in the occurrence, severity, and symptoms of headache episodes in patients with chronic migraine following eptinezumab treatment. METHODS: PROMISE-2 was a double-blind, placebo-controlled, parallel-group trial that randomized adults with chronic migraine to eptinezumab 100 mg, 300 mg, or placebo IV every 12 weeks for up to 24 weeks (2 infusions). Headache episodes (migraine and non-migraine) and their characteristics were reported in daily electronic diaries during the 28-day baseline and throughout the 24-week treatment period. RESULTS: A total of 1072 patients were included in this post hoc analysis. Mean monthly headache days decreased by 8.9 (100 mg) and 9.7 (300 mg) compared to a 7.3 decrease in placebo over the first 4-week interval post initial dose and reductions were maintained throughout the 24-week treatment period. Mean monthly headache episodes also decreased by 8.4 (100 mg) and 9.0 (300 mg) compared to a decrease of 7.1 with placebo. The proportion of headache episodes that were migraine attacks decreased by 11.2% (100 mg), 12.4% (300 mg), and 3.9% (placebo), and among remaining headaches decreases in severe pain, nausea, phonophobia, photophobia, and physical activity limitations were numerically greater than placebo. CONCLUSIONS: Patients with chronic migraine treated with eptinezumab decreased the monthly severity and frequency of headache days and episodes more than placebo. Beyond decreased headache frequency, patients treated with eptinezumab reported a reduction in the percent of remaining headache episodes that were migraine attacks, as well as a decrease in burdensome symptoms of headache episodes, indicating additional decreased headache severity after eptinezumab treatment.Trial registration: ClinicalTrials.gov Identifier: NCT02974153; registered November 23, 2016.

RESUMEN

OBJECTIVE: To compare effects of an initial dose of calcitonin gene-related peptide (CGRP) monoclonal antibody (mAb) antagonists on gastrointestinal (GI) motility in patients with migraine and to explore if the mechanistic difference contributes to GI adverse events (AEs). BACKGROUND: Different frequencies of constipation have been observed between CGRP mAbs that target the ligand (galcanezumab [GMB]) or receptor (erenumab [ERE]). METHODS: Patients (n = 65) with migraine without significant GI symptoms were enrolled in a multi-center, single-blind phase IV clinical trial (NCT04294147) and randomized 1:1 to receive GMB (240 mg; n = 33) or ERE (140 mg; n = 32). GI whole and regional transit times were assessed using a wireless motility capsule 1 week before and 2 weeks after mAb administration. The primary endpoint was change from baseline in colonic transit time (CTT) within each treatment group. Other measures included GI Symptom Rating Scale (GSRS), Bristol Stool Form Scale (BSFS), and spontaneous bowel movement (SBM) evaluation. AEs were monitored throughout the study. RESULTS: Baseline characteristics indicated significant GI transit time variability with minimal GI reported symptoms. While not statistically significant, a numerical mean increase in CTT was observed in ERE patients (n = 28, mean [SD] at baseline: 33.8 [29.4] h; least square [LS] mean [SE] change: 5.8 [5.7] h, 95% confidence interval [CI] -5.7 to 17.2, p = 0.320), while GMB decreased CTT (n = 31, mean [SD] at baseline: 29.3 [24.5] h; LS mean [SE] change: -5.4 [5.4] h, 95% CI -16.2 to 5.5, p = 0.328) compared to baseline. No meaningful changes were observed in other regional transit times. ERE significantly reduced BSFS (LS mean [SE] score -0.5 [0.2], p = 0.004) and SBM (LS mean [SE] -1.2 [0.5], p = 0.0120), and increased GSRS-constipation compared to baseline (LS mean [SE] score 0.3 [0.1], p = 0.016). GMB increased GSRS-constipation (LS mean [SE] score 0.4 [0.1], p = 0.002). There were no discontinuations due to or serious AEs. A higher percentage of treatment-emergent AEs were reported with ERE than GMB (ERE: nine of 32 [28.1%] versus GMB: three of 33 [9.1%]), with constipation the most frequently reported (ERE: five of 32 [15.6%] versus GMB one of 33 [3.0%]). CONCLUSION: While the primary endpoint of this study was not met, secondary and tertiary endpoints support a within- and between-treatment change in GI effects suggesting possible mechanistic differences between ligand (GMB) and receptor (ERE) antagonism.

RESUMEN

BACKGROUND: Erenumab (erenumab-aooe in the US) effectively reduces monthly migraine days in episodic and chronic migraine. This traditional outcome does not capture the intensity of headache pain on days with migraine. METHODS: This post hoc analysis of two pivotal randomized, placebo-controlled studies in patients with episodic migraine and chronic migraine examined the effect of erenumab 70 and 140 mg on migraine pain. Cumulative monthly migraine pain intensity is the sum of the peak pain intensity scores (0 = no migraine to 3 = migraine day with severe pain) on migraine days. Change from baseline in cumulative monthly migraine pain and average monthly pain intensity was assessed over months 4 to 6 for episodic migraine and month 3 for chronic migraine; change in average monthly pain intensity was assessed among monthly migraine days responders/non-responders. RESULTS: Efficacy analysis included 946 patients for the episodic migraine study and 656 patients for the chronic migraine study. Cumulative monthly migraine pain decreased significantly with erenumab versus placebo (p < 0.001, for episodic migraine and chronic migraine). In addition, monthly average migraine pain intensity decreased significantly with erenumab versus placebo for episodic migraine (p < 0.01); decreases were non-significant for chronic migraine. In comparison with placebo-treated patients, a greater proportion of erenumab-treated patients were pain intensity responders regardless of threshold used. Episodic migraine and chronic migraine patients with a ≥50% reduction in monthly migraine days (responders) had a greater reduction in monthly average pain intensity than non-responders. CONCLUSIONS: Erenumab reduced cumulative monthly migraine pain in episodic migraine and chronic migraine patients and significantly reduced monthly average migraine pain in episodic migraine, demonstrating treatment benefit beyond reduction in migraine frequency.Clinical Trial Registration: ClinicalTrials.gov, NCT02456740; ClinicalTrials.gov, NCT02066415.

RESUMEN

OBJECTIVE: To determine reversion rates from chronic migraine to episodic migraine during long-term erenumab treatment. METHODS: A daily headache diary was completed during the 12-week, double-blind treatment phase of a placebo-controlled trial comparing erenumab 70 mg, 140 mg, and placebo, and weeks 1-12, 21-24, 37-40, and 49-52 of the open-label treatment phase. Chronic migraine to episodic migraine reversion rates were assessed over the double-blind treatment phase; persistent reversion to episodic migraine over 24 weeks (double-blind treatment phase through the first 12 weeks in the open-label treatment phase), long-term persistent reversion to episodic migraine over 64 weeks (double-blind treatment phase plus open-label treatment phase); delayed reversion to episodic migraine through the first 12 weeks of the open-label treatment phase among patients remaining in chronic migraine during the double-blind treatment phase. RESULTS: In the double-blind treatment phase, 53.1% (95% confidence interval: 47.8-58.3) of 358 erenumab-treated completers had reversion to episodic migraine; monthly reversion rates to episodic migraine were typically higher among patients receiving 140 mg versus 70 mg. Among 181 completers (receiving erenumab for 64 weeks), 98 (54.1% [95% confidence interval: 46.6-61.6]) had reversion to episodic migraine during the double-blind treatment phase; of those, 96.9% (95% confidence interval: 91.3-99.4) had persistent reversion to episodic migraine, 96.8% (95% confidence interval: 91.1-99.3) of whom had long-term persistent reversion to episodic migraine. Delayed reversion to episodic migraine occurred in 36/83 (43.4% [95% confidence interval: 32.5-54.7]) patients; of these, 77.8% (95% confidence interval: 60.9-89.9) persisted in reversion through week 64. CONCLUSIONS: Patients with reversion to episodic migraine at week 12 will likely persist as episodic migraine with longer-term erenumab; others may achieve delayed reversion to episodic migraine.Clinical trial registration: URL: https://www.clinicaltrials.gov.

RESUMEN

BACKGROUND: Eptinezumab, an anti-calcitonin gene-related peptide monoclonal antibody recently approved in the United States for preventive treatment of migraine in adults, was found to be well tolerated in double-blind, placebo-controlled studies in patients with episodic and chronic migraine. The objective of the PREVAIL study was to evaluate the long-term safety, immunogenicity, and impact on patient-reported outcomes of repeat doses of eptinezumab in patients with chronic migraine. METHODS: PREVAIL was an open-label, phase 3 trial comprising a 48-week treatment phase followed by a second 48-week treatment phase. Adults with chronic migraine received eptinezumab 300 mg by 30-min intravenous administration every 12 weeks for up to 8 doses. Patients were followed for 20 weeks after the final infusion (end-of-study visit at week 104). RESULTS: Overall, 128 adults (mean age, 41.5 years) with chronic migraine were included. During the 2 years, the most frequently reported treatment-emergent adverse events were nasopharyngitis (14.1%), upper respiratory tract infection (7.8%), sinusitis (7.8%), influenza (6.3%), bronchitis (5.5%), and migraine (5.5%). The rate of study-drug discontinuation due to adverse events was 6.3%, which included 3 patients with infusion-related hypersensitivity. The incidence of anti-eptinezumab antibodies peaked at week 24 and declined despite continued dosing, to nondetectable levels at week 104. Improvements in patient-reported outcomes were observed at first assessment (week 4) and generally sustained through week 104. CONCLUSION: In adults with chronic migraine, eptinezumab 300 mg demonstrated a favorable safety profile, limited long-term immunogenicity, early and sustained reductions in migraine-related burden, and improvements in health-related quality of life over 2 years.

RESUMEN

BACKGROUND: Although migraine is less common in older people, preventive treatment of migraine in these individuals may be more challenging due to the presence of multiple comorbidities and polypharmacy. Additionally, evidence for migraine treatment efficacy, safety, and tolerability is limited in this population. We evaluated efficacy, safety, and tolerability of fremanezumab, a fully humanized monoclonal antibody (IgG2Δa) that selectively targets calcitonin gene-related peptide (CGRP), in clinical trial participants aged ≥60 years with episodic migraine (EM) or chronic migraine (CM). METHODS: This analysis included data from 3 randomized, double-blind, placebo-controlled phase 3 studies: the HALO EM study, HALO CM study, and FOCUS study in participants with EM or CM and prior inadequate response to 2-4 migraine preventive medication classes. Participants in all studies were randomized 1:1:1 to receive 12 weeks of subcutaneous treatment with quarterly fremanezumab (Months 1/2/3: EM/CM, 675 mg/placebo/placebo), monthly fremanezumab (Months 1/2/3: EM, 225 mg/225 mg/225 mg; CM, 675 mg/225 mg/225 mg), or matched monthly placebo. RESULTS: These pooled analyses included 246 participants aged ≥60 years. Reductions in monthly migraine days from baseline over 12 weeks were significantly greater with fremanezumab (least-squares mean change from baseline [standard error]: quarterly fremanezumab, - 4.3 [0.59]; monthly fremanezumab, - 4.6 [0.54]) versus placebo (placebo, - 2.3 [0.57]; both P < 0.01 vs placebo). As early as Week 1, significant reductions from baseline in weekly migraine days were observed with fremanezumab versus placebo (both P < 0.01). With fremanezumab treatment versus placebo, a significantly higher proportion of participants achieved ≥50% reduction in monthly migraine days, and significant improvements in disability and quality-of-life outcomes were observed (P < 0.05). Proportions of participants experiencing serious adverse events and adverse events leading to discontinuation were low and similar in the fremanezumab and placebo groups. Efficacy and safety results were comparable to the overall pooled population (N = 2843). CONCLUSIONS: This pooled subgroup analysis demonstrates that fremanezumab treatment is efficacious and well-tolerated over 12 weeks in participants aged ≥60 years with EM or CM. These data may help healthcare providers with clinical decision making and preventive treatment selection for older patients with migraine.

RESUMEN

BACKGROUND: Fremanezumab, a fully humanized monoclonal antibody targeting calcitonin gene-related peptide, has demonstrated efficacy for the preventive treatment of migraine in adults. OBJECTIVE: To evaluate the effect of fremanezumab treatment on acute headache medication use and migraine-associated symptoms in patients with episodic migraine. METHODS: In the Phase 3 HALO trial, patients with episodic migraine were randomized to receive subcutaneous fremanezumab monthly (225 mg at baseline, weeks 4 and 8), fremanezumab quarterly (675 mg at baseline, placebo at weeks 4 and 8), or placebo over a 12-week period. The secondary endpoint was change from baseline in the monthly number of days with use of any acute headache mediation or migraine-specific acute headache medication; exploratory endpoints were change from baseline in the monthly number of days with nausea or vomiting, photophobia, or phonophobia. RESULTS: Of 875 patients randomized, 865 were included in the analysis (monthly, n = 287; quarterly, n = 288; placebo, n = 290). Baseline mean ± standard deviation days with: Any acute headache medication use (monthly: 7.7 ± 3.4; quarterly: 7.8 ± 3.7; placebo: 7.7 ± 3.6), migraine-specific acute headache medication use (6.1 ± 3.1; 6.6 ± 3.1; 7.1 ± 3.0), nausea or vomiting (4.5 ± 3.6; 4.9 ± 3.7; 4.5 ± 3.3) and photophobia and phonophobia (5.5 ± 4.1; 6.3 ± 4.1; 6.0 ± 3.9) were similar among treatment arms. Fremanezumab reduced the number of days of acute headache medication use ([least-squares mean change vs. placebo] monthly: -1.4 [95% confidence interval: -1.84, -0.89], p < 0.001; quarterly: -1.3 [-1.76, -0.82], p < 0.001) and migraine-specific acute headache medication use (monthly: -2.2 [-2.80, -1.56], p < 0.001; quarterly: -2.2 [-2.81, -1.58], p < 0.001) compared with placebo. Fremanezumab also reduced nausea or vomiting, photophobia, and phonophobia compared with placebo. CONCLUSIONS: Fremanezumab reduced the need for acute headache medications, including migraine-specific medications, while treating migraine-associated symptoms in patients with episodic migraine. TRIAL REGISTRATION: Clinicaltrials.gov NCT02629861.

RESUMEN

BACKGROUND: Galcanezumab, 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. METHODS: Data 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. RESULTS: TEAEs 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. CONCLUSIONS: Galcanezumab demonstrated a favorable safety and tolerability profile for up to 1 year of treatment for the prevention of migraine. TRIAL REGISTRATION: Clinical Trials CGAB = NCT02163993, EVOLVE-1 = NCT02614183, EVOLVE-2 = NCT02614196, REGAIN = NCT02614261, and CGAJ = NCT02614287. All were first posted on 25 November 2015, except CGAB posted on 16 June 2014, and before enrolling the first patient.

RESUMEN

BACKGROUND: Cluster headache (CH) is a highly disabling primary headache disorder. To date, characterization of outcomes in the preventive treatment of episodic CH, including precise definitions of clinically meaningful attack frequency reduction and impact on acute treatment management, is lacking. METHODS: This was a Phase 3, randomized, double-blind, placebo-controlled study in patients (men or women aged 18-65 years) diagnosed with episodic CH as defined by the International Classification of Headache Disorders-3 beta criteria. In this post hoc analysis, we evaluated the median time-to-first occurrence of ≥50, ≥75, or 100% reduction from baseline in CH attack frequency, and impact on acute medication use. An anchor-based assessment of clinically relevant attack frequency reduction using the Patient Global Impression of Improvement (PGI-I) scores at Week 4 was also assessed. RESULTS: The median time-to-first occurrence of ≥50, ≥75, or 100% reduction from baseline in CH attacks was consistently shorter (9-10 days sooner) with galcanezumab vs placebo (median [95% confidence interval, 95% CI]: ≥50%, 5 days [4.0 to 7.0] vs 14 days [6.0 to 19.0]; ≥75%, 11 days [7.0 to 16.0] vs 21 days [13.0 to 26.0]; 100%, 22 days [16.0 to 37.0] vs 32 days [23.0 to 34.0]). Mean reduction from baseline in the overall frequency of weekly pooled acute medication use across Weeks 1-3 was significantly greater with galcanezumab vs placebo (11.0 vs 5.5; odds ratio, OR [95% CI]: 5.52 [1.02, 10.01]; P value = .017). Patients reporting "much better" on the PGI-I experienced a median weekly CH attack reduction of approximately 43% from baseline across Weeks 1-3. The overall odds of achieving an attack reduction threshold of 43% across Weeks 1-3 was significantly higher with galcanezumab vs placebo (Weeks 1-3: OR [95% CI], 2.60 [1.3 to 5.3]). CONCLUSIONS: Faster median time-to-first occurrence of response rates, lower frequency of pooled acute medications use, and a greater proportion of patients achieving a response anchored by patient-reported improvement were observed for galcanezumab vs placebo.

RESUMEN

OBJECTIVE: Evaluate the safety and tolerability of oral rimegepant when used for acute treatment concomitantly with a monoclonal antibody (mAb) targeting the calcitonin gene-related peptide (CGRP) ligand or receptor (CGRP mAb) for the preventive treatment of migraine. BACKGROUND: The efficacy of CGRP mAbs for the preventive treatment of migraine and the small molecule CGRP receptor antagonist rimegepant for acute treatment has been demonstrated in randomized controlled clinical trials. Over the past few years, the US Food and Drug Administration has approved 4 CGRP mAbs for the preventive treatment of migraine and 2 small molecule CGRP receptor antagonists for the acute treatment of migraine. A previous case report of 2 patients receiving concomitant treatment with rimegepant and erenumab suggested that rimegepant may be safely used as acute treatment in patients who are also receiving a preventive regimen involving CGRP mAbs. We report here 13 additional patients with migraine who simultaneously used rimegepant and either erenumab, fremanezumab, or galcanezumab and assess the rate of on-treatment adverse events (AEs). METHODS: This was a substudy nested within a multicenter, open-label, long-term safety study in adults with 2-14 monthly migraine attacks of moderate to severe pain intensity. A subgroup experiencing 2-8 monthly attacks and taking a stable dose of a CGRP mAb also took rimegepant 75 mg as needed up to once daily for acute treatment for 12 weeks. RESULTS: The 13 patients (11 women [85%]; mean age 49.9 years) enrolled in the substudy were being treated with CGRP mAbs (erenumab [n = 7], fremanezumab [n = 4], or galcanezumab [n = 2]). Mean (SD) time in the rimegepant treatment period was 9.6 (4.6) weeks. Mean (SD) 4-week rimegepant exposure was 7.8 (5.5) doses; a total of 224 doses were taken. Five (38%) patients reported ≥1 on-treatment AE. Of these, 2 (15%) patients had mild or moderate nasopharyngitis; no other AEs occurred in ≥2 patients. Three patients had AEs of mild or moderate severity that were considered potentially treatment-related. No patients had serious AEs, AEs leading to discontinuation, or aminotransferase levels >3× the upper limit of normal. CONCLUSION: Rimegepant, when used as an oral acute treatment in patients receiving CGRP mAbs as preventive treatment, was well tolerated; no safety issues were identified. Studies involving larger patient populations are needed to confirm these findings.

RESUMEN

OBJECTIVE: We explore factors that may have contributed to differences in treatment-emergent adverse events in the phase 2 and phase 3 lasmiditan clinical trials. BACKGROUND: Phase 2 and phase 3 trials showed that the centrally penetrant 5-HT1F agonist, lasmiditan, was effective; higher frequency and severity of adverse events (AEs) were seen in phase 2. METHODS: This work represents a hybrid of a review of primary documents and study reports with additional post hoc analyses. Protocols, informed consents, data collection forms, and methodologies were reviewed. This information was supplemented by results from the clinical study reports and post hoc analyses of individual patient data from each trial. RESULTS: For lasmiditan 100 and 200 mg, in phase 2, the incidence of ≥1 AE was 72-86% (26% severe), while in phase 3 was 36-43% (2% severe). The most common AEs in all studies were CNS-related. The phase 2 consent form was more descriptive of AEs than phase 3. In phase 2, patients recorded AEs and severity in a paper diary that warned about drowsiness and dizziness. In phase 3, patients recorded in electronic diaries whether they experienced unusual feelings after dosing with lasmiditan that they had not felt with a migraine before, and were contacted to determine if an AE had occurred. In phase 2, the AE Schwindel was variably translated from German as "vertigo" or "dizziness," while phase 3 vertigo cases were queried to ensure there was a sensation of rotation or movement. History of recurrent dizziness and/or vertigo was exclusionary in phase 3. CONCLUSIONS: This work illustrates how informed consent wording, AE collection methods, translation, exclusion criteria, and other factors may be important determinants for reporting of the frequency and severity of AEs in clinical trials.

RESUMEN

OBJECTIVES: To address the need for long-term lasmiditan data, the GLADIATOR study evaluated the safety (primary) and efficacy (secondary) of lasmiditan for the intermittent, acute treatment of migraine attacks for up to 1 year. METHODS: In this prospective, randomized, open-label, Phase 3 study, patients who had completed either of two single-attack studies were offered the opportunity to be randomized 1:1 to lasmiditan 100 mg or 200 mg. Patients were asked to use lasmiditan as the first treatment for each new migraine attack of at least moderate severity. Assessments occurred at baseline and at prespecified time increments up to 48 hours after each dose of study drug using an electronic diary, and safety was assessed throughout the study. Migraine Disability Assessment (MIDAS) was assessed at each visit. RESULTS: As of the cut-off date for this interim analysis (6 March 2018), 1978 patients had received ≥ 1 lasmiditan dose and treated 19,058 migraine attacks. Overall, treatment-emergent adverse events (TEAEs) were similar to those in the single-attack studies and included dizziness (18.6%), somnolence (8.5%), and paresthesia (6.8%). The frequency of TEAEs generally decreased with subsequent attacks. No treatment-related serious adverse events and no cardiovascular TEAEs potentially due to vasoconstriction were observed. For both lasmiditan doses, efficacy measures were generally consistent over study quarters and treated attacks. Overall, across all treated attacks at 2 hours post-dose, pain freedom was observed in 26.9% of the attacks treated with lasmiditan 100 mg and 32.4% of the attacks treated with lasmiditan 200 mg. MIDAS total scores decreased over time. CONCLUSIONS: The interim results of this long-term study showed intermittent lasmiditan (100 mg and 200 mg) to be generally well tolerated and efficacious for the acute treatment of migraine over a 1-year period. Trial registration number: NCT02565186; https://clinicaltrials.gov/ct2/show/NCT02565186.

RESUMEN

BACKGROUND: Efficacy and safety of erenumab have been evaluated in a comprehensive clinical development program resulting in approval for migraine prevention in over 40 countries to date. METHODS: This integrated safety analysis included four double-blind randomized trials and their extensions (up to three-plus years). Safety endpoints included exposure-adjusted patient incidences of adverse events, serious adverse events, and anti-erenumab antibodies. RESULTS: In all, 2375 of the patients randomized across the four studies received at least one dose of erenumab (70 mg or 140 mg), with cumulative exposure of 2641.2 patient-years. Exposure-adjusted adverse event rates during the double-blind treatment phase were similar to placebo, with the exception of injection-site reactions (17.1 vs. 10.8 per 100 patient-years), constipation (7.0 vs. 3.8 per 100 patient-years), and muscle spasm (2.3 vs. 1.2 per 100 patient-years). During the long-term extensions, adverse events reported were similar to those observed during the double-blind treatment phase, and rates of injection site reactions, constipation, and muscle spasm were reported at lower rates than in the double-blind treatment phase. There were two deaths reported, both confounded by pre-existing conditions. CONCLUSIONS: This pooled safety analysis revealed a favorable and stable adverse event profile over time for erenumab with more than three years of exposure.

RESUMEN

Objective To determine the efficacy, tolerability, and safety of ascending doses of Adhesive Dermally-Applied Microarray (ADAM) zolmitriptan versus placebo for acute migraine treatment. Background ADAM is a novel patient-administered system for intracutaneous drug administration. In a phase 1 pharmacokinetic study, zolmitriptan administered using ADAM had much faster absorption than oral administration with higher exposure in the first two hours. Methods This was a multicenter, randomized, double-blind, placebo-controlled, parallel-group Phase 2b/3 study evaluating ADAM zolmitriptan 1 mg, 1.9 mg, and 3.8 mg versus placebo. Co-primary endpoints were pain freedom and freedom from most bothersome other migraine-associated symptom 2 hours post-dose. Results Of patients treated with ADAM zolmitriptan 3.8 mg or placebo, 41.5% and 14.2%, respectively were pain-free 2 hours post-dose ( p = 0.0001) and 68.3% and 42.9% were free from their most bothersome other symptom ( p = 0.0009). Due to the fixed sequential testing methodology, formal statistical significance was not established for secondary endpoints. However, the proportion of patients who were photophobia-free, phonophobia-free, and nausea-free at 2 hours post-dose was higher in the ADAM zolmitriptan 3.8 mg group compared with placebo, as were the percentages of patients who were pain-free, and who experienced pain relief up to 48 hours post-dose. Systemic adverse events were consistent with previous triptan trials, and included dizziness, paresthesia, muscle tightness, and nausea, all of which occurred in < 5% of patients in any group. Application site reactions were generally mild and resolved within 48 hours, although erythema and bruising persisted for longer periods in some patients. Conclusion ADAM zolmitriptan 3.8 mg provides effective relief of migraine headache and associated most bothersome symptoms compared with placebo, and is well-tolerated. ClinicalTrials.gov NCT02745392.
