Phase 3 randomized, placebo-controlled, double-blind study of lasmiditan for acute treatment of migraine.

ABSTRACT: Lasmiditan, a serotonin 5-HT1F receptor agonist, was effective for acute treatment of patients with migraine in a phase 3 double-blind randomized controlled study. The current study was designed to replicate these findings in a generalizable population of patients with migraine, including those with a cardiovascular medical history. This prospective, double-blind, phase 3 multicentre study randomly assigned patients with migraine with and without aura (1:1:1:1 ratio) to oral lasmiditan 200 mg, 100 mg, 50 mg, or placebo. Patients were instructed to dose at home within 4 h of onset of migraine attack of at least moderate intensity and not improving. The primary objective was to assess the proportion of patients' headache pain-free and most bothersome symptom-free at 2 h post-dose for each dose of lasmiditan versus placebo (NCT02605174). Patients (n = 3005) were assigned and treated (n = 2583, safety population): 1938 lasmiditan (200 mg n = 528, 100 mg n = 532, and 50 mg n = 556 included in primary analysis) and 645 placebo (540 included in primary analysis). Most patients (79.2%) had ?1 cardiovascular risk factor at baseline, in addition to migraine. Lasmiditan was associated with significantly more pain freedom at 2 h (lasmiditan 200 mg: 38.8%, odds ratio 2.3, 95% confidence interval 1.8-3.1, P < 0.001; 100 mg: 31.4%, odds ratio 1.7, 1.3-2.2, P < 0.001; 50 mg: 28.6%, odds ratio 1.5, 1.1-1.9, P = 0.003 versus placebo 21.3%) and freedom from most bothersome symptom at 2 h (lasmiditan 200 mg: 48.7%, odds ratio 1.9, 95% confidence interval 1.4-2.4, P < 0.001; 100 mg: 44.2%, odds ratio 1.6, 1.2-2.0, P < 0.001; 50 mg: 40.8%, odds ratio 1.4, 1.1-1.8, P = 0.009 versus placebo 33.5%). Treatment-emergent adverse events were reported in 253 of 649 (39.0%), 229 of 635 (36.1%), and 166 of 654 (25.4%) of patients on lasmiditan 200, 100, and 50 mg, respectively, versus 75 of 645 (11.6%) on placebo. Most adverse events were CNS-related and included dizziness, somnolence and paraesthesia. Lasmiditan was effective at 2 h post-dose for acute treatment of migraine at all oral doses tested. Efficacy and safety were consistent with the previous phase 3 study.

Project description:OBJECTIVE:To expand on available information on the efficacy of oral lasmiditan for the acute treatment of migraine with particular focus on the timing of the effect and on its impact on migraine-associated symptoms. BACKGROUND:Lasmiditan is a novel selective 5-hydroxytryptamine 1F receptor agonist that lacks vasoconstrictive activity. In 2 phase 3 studies, SAMURAI and SPARTAN, lasmiditan met primary and key secondary efficacy endpoints at 2 hours following initial dose. METHODS:Integrated analyses were completed from 2 phase 3 clinical trials, SPARTAN and SAMURAI. Baseline data and data collected every 30 minutes up to 2 hours after taking lasmiditan (50, 100, or 200 mg) or placebo were analyzed to determine the onset of efficacy. A total of 5236 patients were randomized to be treated with placebo (N = 1493), lasmiditan 50 mg (N = 750), lasmiditan 100 mg (N = 1498), or lasmiditan 200 mg (N = 1495). Data were analyzed to determine the onset of improvement for the following efficacy measures: pain freedom, most bothersome symptom freedom, pain relief, freedom from associated individual symptoms (photophobia, phonophobia, or nausea), total migraine freedom (defined as pain freedom and freedom from associated symptoms), and freedom from migraine-related functional disability. Time to meaningful headache relief and time to first become pain free were also analyzed. RESULTS:Significantly higher rates of pain freedom (100 mg, 10.0%, P = .012; 200 mg, 15.5%, P < .001; Placebo, 7.0%) and total migraine freedom (100 mg, 8.9%, P = .017; 200 mg, 12.4%, P < .001; Placebo, 6.1%) were achieved starting at 60 minutes in 100- and 200-mg lasmiditan-treated groups compared with placebo group. Rates of freedom from most bothersome symptom (100 mg, 11.1%, P = .015; 200 mg, 13.0%, P < .001; Placebo, 7.9%), and pain relief (100 mg, 17.5%, P = .007; 200 mg, 19.1%, P < .001; Placebo, 13.4%) were significantly higher starting as early as 30 minutes in lasmiditan 100- and 200-mg lasmiditan-treated groups. A significantly higher percentage of patients in the 200-mg lasmiditan-treated group achieved freedom from photophobia (13.7%, P = .005; Placebo, 9.2%) and phonophobia (17.4%, P = .042; Placebo, 13.4%) starting at 30 minutes. A significantly greater proportion of patients in the 200-mg lasmiditan-treated group achieved freedom from migraine-related functional disability starting at 60 minutes (16.4%, P < .001; Placebo, 11.1%). All efficacy measures, except for freedom from nausea, were statistically significant after lasmiditan treatment (50, 100, or 200 mg) compared with placebo at 90 and 120 minutes. Finally, patients taking lasmiditan had a higher likelihood of achieving meaningful headache relief and becoming headache pain free within 24 hours compared with those taking placebo (P < .001). CONCLUSIONS:Patients treated with lasmiditan for a migraine attack reported an earlier onset of efficacy compared with those treated with placebo. Some of the efficacy measures such as pain relief demonstrated improvement as early as the first assessment at 30 minutes after 100- or 200-mg lasmiditan treatment.

Project description:ObjectiveTo evaluate the efficacy and safety of lasmiditan in Japanese adults with migraine.BackgroundGlobal clinical studies have demonstrated the efficacy and safety of lasmiditan in the acute treatment of migraine.MethodsThis was a multicenter, randomized, double-blind, placebo-controlled, phase 2 study in Japan (NCT03962738), which enrolled adults with migraine with or without aura. Participants were randomized 7:3:7:6 to placebo, lasmiditan 50 mg, 100 mg, or 200 mg to be self-administered orally within 4 h of onset of a single moderate-to-severe migraine attack. Participants recorded their response to treatment prior to dosing and for 48 h postdose. The primary endpoint was headache pain freedom at 2 h postdose.ResultsParticipants (N = 846) were randomized and treated (N = 691, safety; N = 682, modified intent-to-treat). At 2 h postdose, a significantly higher proportion of participants were headache pain-free in the lasmiditan 200 mg (40.8%, 73/179; odds ratio 3.46 [95% confidence interval 2.17 to 5.54]; p < 0.001; primary objective) and 100 mg groups (32.4%, 67/207; odds ratio 2.41 [1.51 to 3.83]; p < 0.001) compared with the placebo group (16.6%, 35/211), whereas the lasmiditan 50 mg group had a numerically higher proportion of participants headache pain-free (23.5%, 20/85; odds ratio 1.55 [0.83 to 2.87]; p = 0.167) compared with placebo. A statistically significant linear dose-response relationship for pain freedom was achieved at 2 h by a Cochran-Armitage trend test (p < 0.001). Lasmiditan treatment was also associated with headache pain relief, most bothersome symptom freedom, and improvement on disability and Patient Global Impression of Change outcomes. The majority of treatment-emergent adverse events were mild and of short duration, the most common of which were dizziness (39.4%; 188/477), somnolence (19.3%; 92/477), and malaise (10.5%; 50/477) in all lasmiditan groups, with no serious adverse events reported.ConclusionsLasmiditan was well tolerated and effective for the acute treatment of Japanese patients with migraine, consistent with global phase 3 studies.

Project description:BACKGROUND:In addition to the increased risk for cardiovascular (CV) disease and CV events associated with migraine, patients with migraine can also present with a number of CV risk factors (CVRFs). Existing treatment options can be limited due to contraindications, increased burden associated with monitoring, or patient avoidance of side effects. Safe and effective migraine treatment options are needed for patients with migraine and a history of CV or cerebrovascular disease or with increased risk for CV events. This analysis was designed to evaluate the safety and efficacy of oral lasmiditan, a selective serotonin 5-hydroxytryptamine 1F receptor agonist, in acute treatment of migraine attacks in patients with CVRFs. METHODS:SAMURAI and SPARTAN were similarly designed, Phase 3, randomized, double-blind, placebo-controlled trials in adults treating a single migraine attack with lasmiditan 50, 100, or 200?mg. Both studies included patients with CVRFs, and SPARTAN allowed patients with coronary artery disease, clinically significant arrhythmia, or uncontrolled hypertension. Efficacy and safety of lasmiditan in subgroups of patients with differing levels of CVRFs are reported. For efficacy analyses, logistic regression was used to assess treatment-by-subgroup interactions. For safety analyses, Cochran-Mantel-Haenszel test of general association evaluated treatment comparisons; Mantel-Haenszel odds ratio assessed significant treatment effects. RESULTS:In this pooled analysis, a total of 4439 patients received ?1 dose of study drug. A total of 3500 patients (78.8%) had ?1 CVRF, and 1833 patients (41.3%) had ?2 CVRFs at baseline. Both trials met the primary endpoints of headache pain freedom and most bothersome symptom freedom at 2?h. The presence of CVRFs did not affect efficacy results. There was a low frequency of likely CV treatment-emergent adverse events (TEAEs) overall (lasmiditan, 30 [0.9%]; placebo, 5 [0.4%]). There was no statistical difference in the frequency of likely CV TEAEs in either the absence or presence of any CVRFs. The only likely CV TEAE seen across patients with ?1, ? 2, ? 3, or???4 CVRFs was palpitations. CONCLUSIONS:When analyzed by the presence of CVRFs, there was no statistical difference in lasmiditan efficacy or the frequency of likely CV TEAEs. Despite the analysis being limited by a single-migraine-attack design, the lack of differences in efficacy and safety with increasing numbers of CVRFs indicates that lasmiditan might be considered in the treatment algorithm for patients with CVRFs. Future studies are needed to assess long-term efficacy and safety.

Project description:ObjectiveEvaluate the efficacy, safety, and tolerability of zavegepant nasal spray in the acute treatment of migraine.BackgroundCalcitonin gene-related peptide-targeting agents are a novel class of therapeutics for migraine, but none are currently available as a nonoral option for acute treatment. Zavegepant, a high-affinity, selective, and structurally unique calcitonin gene-related peptide-receptor antagonist in late-stage development, is formulated as a nasal spray for the acute treatment of migraine.MethodsThis randomized, dose-ranging, placebo-controlled, Phase 2/3 trial in adults aged ≥18 years with migraine (NCT03872453) was conducted at US study sites. Participants were randomized by an interactive web response system and treated a single attack of moderate to severe pain intensity with zavegepant nasal spray 5, 10, 20 mg, or placebo. Coprimary efficacy endpoints were pain freedom and freedom from the most bothersome symptom at 2 h postdose.ResultsOf the 1673 participants aged 18 to 79 years who were randomized, 1588 were treated with study medication, and 1581 (mean age 40.8 years, 85.5% female) were analyzed for efficacy: zavegepant 5 mg (n = 387), 10 mg (n = 391), 20 mg (n = 402), and placebo (n = 401). Zavegepant 10 and 20 mg were more effective than placebo on the coprimary endpoints of pain freedom at 2 h postdose (placebo: 15.5% [98.3% confidence interval (CI), 11.1, 19.8]; 10 mg: 22.5% [98.3% CI, 17.5, 27.6; p = 0.0113]; 20 mg: 23.1% [98.3% CI, 18.1, 28.2; p = 0.0055]) and freedom from the most bothersome symptom at 2 h postdose (placebo: 33.7% [98.3% CI, 28.0, 39.3]; 10 mg: 41.9% [98.3% CI, 36.0, 47.9; p = 0.0155]; 20 mg: 42.5% [98.3% CI, 36.6, 48.4; p = 0.0094]). Findings for the 5 mg dose were not significant. The most common treatment-emergent adverse events with zavegepant 10 and 20 mg and placebo were dysgeusia (13.5% to 16.1% vs. 3.5%), nausea (2.7% to 4.1% vs. 0.5%), and nasal discomfort (1.3% to 5.2% vs. 0.2%). Most adverse events were mild or moderate and resolved without treatment. There was no signal of hepatotoxicity.ConclusionZavegepant nasal spray, in single doses of 10 or 20 mg, was effective for the acute treatment of migraine, with a favorable safety profile. Additional research is needed to confirm its potential as a nonoral medication for the acute treatment of migraine.

Project description:OBJECTIVE:To assess the efficacy and safety of a remote electrical neuromodulation (REN) device for the acute treatment of migraine. BACKGROUND:There is a significant unmet need for novel effective well-tolerated acute migraine treatments. REN is a novel acute migraine treatment that stimulates upper arm peripheral nerves to induce conditioned pain modulation - an endogenous analgesic mechanism in which conditioning stimulation inhibits pain in remote body regions. A recent pilot study showed that REN can significantly reduce headache. We have conducted a randomized, double-blind, sham-controlled study to further evaluate the efficacy and safety of REN for the acute treatment of migraine. METHODS:This was a randomized, double-blind, sham-controlled, multicenter study conducted at 7 sites in the United States and 5 sites in Israel. Two hundred and fifty-two adults meeting the International Classification of Headache Disorders criteria for migraine with 2-8 migraine headaches per month were randomized in a 1:1 ratio to active or sham stimulation. A smartphone-controlled wireless device was applied for 30-45 minutes on the upper arm within 1 hour of attack onset; electrical stimulation was at a perceptible but non-painful intensity level. Migraine pain levels were recorded at baseline, 2, and 48 hours post-treatment. Most bothersome symptoms (MBS) were also recorded. The primary efficacy endpoint was the proportion of participants achieving pain relief at 2 hours post-treatment (improvement from severe or moderate pain to mild or none, or from mild pain to none). Relief of MBS and pain-free at 2 hours were key secondary endpoints. RESULTS:Active stimulation was more effective than sham stimulation in achieving pain relief (66.7% [66/99] vs 38.8% [40/103]; therapeutic gain of 27.9% [CI95% , 15.6-40.2]; P < .0001), pain-free (37.4% vs 18.4%, P = .003), and MBS relief (46.3% vs 22.2%, P = .0008) at 2 hours post-treatment. The pain relief and pain-free superiority of the active treatment was sustained 48 hours post-treatment. The incidence of device-related adverse events was low and similar between treatment groups (4.8% [6/126] vs 2.4% [3/126], P = .499). CONCLUSIONS:REN provides superior clinically meaningful relief of migraine pain and MBS compared to placebo, offering a safe and effective non-pharmacological alternative for acute migraine treatment.

Project description:Migraine is one of the most common and debilitating neurological disorders worldwide. External Trigeminal Nerve Stimulation (e-TNS) is a non-pharmacological, non-invasive therapeutic alternative for patients with migraine. The TEAM study was a prospective, multicenter, randomized, double-blind, sham-controlled, Phase 3 trial for 2-h, continuous, e-TNS treatment of a single moderate or severe migraine attack at home. A total of 538 adults meeting the International Classification of Headache Disorders 3rd edition criteria for 2-8 migraine headache days per month were recruited and randomized in a 1:1 ratio to 2-h active or sham stimulation. Migraine pain levels and most bothersome migraine-associated symptoms (MBS) were recorded at baseline, 2 h, and 24 h using a paper diary. The primary endpoints for the study were pain freedom at 2 h and freedom from the MBS at 2 h. The secondary endpoints were pain relief at 2 h, absence of most bothersome migraine-associated symptoms (MBSs) at 2 h, acute medication use within 24 h after treatment, sustained pain freedom at 24 h, and sustained pain relief at 24 h. Adverse event data was also collected and compared between groups. Five hundred thirty-eight patients were randomized to either the verum (n = 259) or sham (n = 279) group and were included in an intention-to-treat analysis. The percentage of patients with pain freedom at 2 h was 7.2% higher in verum (25.5%) compared to sham (18.3%; p = 0.043). Resolution of most bothersome migraine-associated symptom was 14.1% higher in verum (56.4%) compared to sham (42.3%; p = 0.001). With regards to secondary outcomes, pain relief at 2 h was 14.3% higher in verum (69.5%) than sham (55.2%; p = 0.001), absence of all migraine-associated symptoms at 2 h was 8.4% higher in verum (42.5%) than sham (34.1%; p = 0.044), sustained pain freedom and pain relief at 24 h was 7.0% and 11.5% higher in verum (22.8 and 45.9%) than sham (15.8 and 34.4%; p = 0.039 and .006, respectively). No serious adverse events were reported. Treatment with 2-h e-TNS is a safe and effective, non-invasive, and non-pharmacological alternative for the acute treatment of migraine attacks in an at-home setting.Trial registration Clinicaltrials.gov Identifier: NCT03465904.

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.
