Abstract

Objective To assess the efficacy and safety of lasmiditan in the acute treatment of migraine.

Methods Adult patients with migraine were randomized (1:1:1) to a double-blind dose of oral lasmiditan 200 mg, lasmiditan 100 mg, or placebo and were asked to treat their next migraine attack within 4 hours of onset. Over 48 hours after dosing, patients used an electronic diary to record headache pain and the presence of nausea, phonophobia, and photophobia, one of which was designated their most bothersome symptom (MBS).

Results Of the 1,856 patients who treated an attack, 77.9% had ≥1 cardiovascular risk factors in addition to migraine. Compared with placebo, more patients dosed with lasmiditan 200 mg were free of headache pain at 2 hours after dosing (32.2% vs 15.3%; odds ratio [OR] 2.6, 95% confidence interval [CI] 2.0–3.6, p< 0.001), similar to those dosed with lasmiditan 100 mg (28.2%; OR 2.2, 95% CI 1.6–3.0, p< 0.001). Furthermore, compared with those dosed with placebo, more patients dosed with lasmiditan 200 mg (40.7% vs 29.5%; OR 1.6, 95% CI 1.3–2.1, p< 0.001) and lasmiditan 100 mg (40.9%; OR 1.7, 95% CI, 1.3–2.2, p< 0.001) were free of their MBS at 2 hours after dosing. Adverse events were mostly mild or moderate in intensity.

Conclusions Lasmiditan dosed at 200 and 100 mg was efficacious and well tolerated in the treatment of acute migraine among patients with a high level of cardiovascular risk factors.

ClinicalTrials.gov identifier NCT02439320.

Classification of evidence This study provides Class I evidence that for adult patients with migraine, lasmiditan increases the proportion of subjects who are headache pain free at 2 hours after treating a migraine attack.

Migraine is ranked by the World Health Organization as the world's second leading cause of disability.1 Triptans, a class of serotonin 5-HT1B/1D receptor agonists (some of which also act at 5-HT1F receptors), are the most widely used specific antimigraine therapies.2 Triptans cause vasoconstriction by activation of 5-HT1B receptors,3,–,5 conferring a small risk of serious cardiovascular adverse events.6 Triptans are contraindicated in patients with certain cardiovascular conditions and events such as vascular disease, hemiplegic migraine, uncontrolled hypertension, and stroke, and product labels contain warnings for patients with cardiovascular risk factors.7,8 Because cardiovascular conditions, events, and procedures are common in migraine9,–,11 and because ≈30% to 40% of patients with migraine do not respond to triptans,12 there is a need for new acute migraine treatments.

Lasmiditan is a high-affinity, highly selective 5-HT1F receptor agonist that acts on the trigeminal system without causing vasoconstriction because of its low affinity for 5-HT1B receptors.13 Lasmiditan is being developed as an acute therapy for migraine to address significant unmet needs in patients with cardiovascular risk factors, those with stable cardiovascular disease, or patients who respond poorly to their current treatment. In a phase 2B study, oral lasmiditan was safe and effective in the acute treatment of migraine.14 In this first phase 3, prospective, randomized, double-blind, placebo-controlled study to assess the efficacy and safety of lasmiditan (200 and 100 mg) in the acute treatment of migraine, patients with cardiovascular risk factors were intentionally enrolled. This phase 3 pivotal trial, with a prespecified modified intent-to-treat (mITT) analysis population, was conducted under Special Protocol Assessment with the US Food and Drug Administration (FDA).15

Methods

Primary research question

This study in patients with migraine headache pain was conducted to evaluate the efficacy of lasmiditan 200 and 100 mg vs placebo as measured by the proportion of patients who became headache pain free (primary endpoint 200 mg, key secondary endpoint 100 mg) and most bothersome symptom (MBS) free (key secondary endpoint) at 2 hours. This study provides Class I evidence that for adult patients with migraine, lasmiditan increases the proportion of subjects who are headache pain free at 2 hours after treating a migraine attack.

Standard protocol approvals, registrations, and patient consents

The study was conducted in accordance with the International Conference on Harmonisation Good Clinical Practice guideline and local regulatory requirements. The study protocol was approved by an independent ethics committee or institutional review board at each study site. All patients provided written informed consent before the start of the study. The study was registered at ClinicalTrials.gov (identifier: NCT02439320).

Study population

Key patient inclusion criteria were as follows: male or female; ≥18 years of age; a diagnosis of migraine with or without aura fulfilling the International Headache Society diagnostic criteria 1.1 or 1.2.116; a history of disabling migraine for at least 1 year; a Migraine Disability Assessment (MIDAS)17,18 total score of ≥11; migraine onset before 50 years of age; and a history of 3 to 8 migraine attacks per month (<15 headache days per month).

Key exclusion criteria were a history within the past 12 months of chronic migraine or other forms of primary or secondary chronic headache disease (e.g., hemicranias continua) or medication-overuse headache with a headache frequency of >15 headache days per month; initiation of or change in migraine preventive medication within 3 months before screening; and known coronary artery disease, clinically significant arrhythmia, or uncontrolled hypertension. Patients at increased risk for seizures were also excluded.

Study design

This randomized, double-blind, placebo-controlled study was initiated on April 27, 2015, and completed on August 12, 2016. Patients were enrolled by study site personnel at 99 centers in the United States.

At the screening visit (visit 1), patient eligibility was assessed, and patients were randomized (1:1:1) to a first dose of lasmiditan 200 mg, lasmiditan 100 mg, or placebo. Patients were also randomly allocated to a second dose of lasmiditan or placebo for rescue or recurrence of migraine (patients in the lasmiditan 200 mg group were randomized [2:1] to lasmiditan 200 mg or placebo as the second dose; patients in the lasmiditan 100 mg group were randomized [2:1] to lasmiditan 100 mg or placebo as the second dose; and all patients in the placebo group received placebo as the second dose). Patients were instructed not to treat an attack until their eligibility had been confirmed by phone (within 7 days) after completion of all screening evaluations, including laboratory tests.

Patients were randomized through a central randomization process by interactive response technology. Patients were stratified (yes or no) for use of concomitant migraine preventive medication. A randomization number and study drug card number were assigned to each patient. Study drugs (lasmiditan and matching placebo, manufactured by Aptuit, Verona, Italy) took the form of white, film-coated tablets with no markings provided in double-blinded treatment packs containing 2 doses.

Ineligible patients had their end-of-study visit (visit 2) within 7 days of phone contact to return the study drug.

Eligible patients entered an outpatient treatment period in which they were asked to treat their next migraine attack within 4 hours of onset, provided that the headache severity was either moderate or severe and not improving. Patients recorded their response to the first dose over the next 48 hours using an electronic diary.

Patients were asked not to use rescue medication until at least 2 hours after dosing with the study drug; if the migraine did not respond at 2 hours, the second dose of study drug could be taken up to 24 hours after the first dose provided that no other rescue medication had been used. If the migraine responded within 2 hours (i.e., the headache became pain free) but then recurred after 2 hours, the second dose of study drug could be taken up to 24 hours after the first dose. The electronic diary was restarted if a patient took a second dose.

Patients who entered the treatment period had their end-of-study visit (visit 2) within 7 days of the treated attack or after 8 weeks if no attack was treated.

Outcome measures

At the time of migraine attack, before dosing, patients used the electronic diary to record the date and time of migraine onset and the level of headache pain and indicated the presence or absence of associated symptoms of migraine (nausea, phonophobia, and photophobia). Headache pain was rated by patients using the International Headache Society 4-point headache severity rating scale: none (0), mild (1), moderate (2), or severe (3).19 From the list of associated symptoms, patients selected the one they considered to be the MBS. Patients also recorded the date and time of taking the first dose of study drug. Baseline was defined as the last available measurement before the first dose.

With regard to efficacy, the electronic diary collected the following data at baseline and at 0.5, 1, 1.5, 2, 3, 4, 24, and 48 hours after dose: the current level of headache pain, the presence or absence of associated symptoms of migraine (nausea, phonophobia, photophobia), the presence or absence of vomiting, and the level of disability. Patient-reported level of disability (degree of interference with normal activities) was rated with a 4-point scale: not at all (0); mild interference (1); marked interference (2); and completely, needs bed rest (3). In addition, at 2 hours after dose, patients recorded their global impression of change using a 7-point scale: very much better, much better, a little better, no change, a little worse, much worse, or very much worse.

With regard to safety and tolerability, the electronic diary asked patients if they felt “anything unusual” since taking the study medication that they had not felt with a migraine before; if yes, they received a follow-up phone call from the site. At the end-of-study visit, safety was assessed by adverse events, clinical laboratory parameters, physical examination, vital signs, ECGs, and the Columbia Suicide Severity Rating Scale.20 A treatment-emergent adverse event (TEAE) was defined as an event that started or worsened after the first dose of study medication (i.e., it did not present with the migraine) and occurred within 48 hours of the last dose.

The electronic diary also documented the use of rescue/recurrence medication and any other concomitant medication that had not been recorded at the screening visit.

Data analysis

The sample size was determined on the basis of the proportion of patients who were headache pain free at 2 hours in a phase 2B study (18.8% for lasmiditan 200 mg, 13.6% for lasmiditan 100 mg, and 7.4% for placebo).14 With a 1-sided, 2-sample comparison at the 2.5% level of significance, a sample size of 570 patients per treatment group (as defined by the first dose) provided >90% power to detect a difference in the proportion of patients who were headache pain free at 2 hours for lasmiditan 200 mg and lasmiditan 100 mg.

The safety population was defined as all randomized patients who used at least 1 dose of study drug, regardless of whether they underwent any study assessments. The intent-to-treat (ITT) population was defined as all patients in the safety population who recorded any postdose headache severity or symptom assessments in the electronic diary, and the mITT population was defined as all patients in the ITT population who treated a migraine attack within 4 hours of onset.

The primary efficacy endpoint was a comparison between lasmiditan 200 mg and placebo of the proportion of patients who were headache pain free at 2 hours after the first dose of study medication (in the mITT population). Endpoints were analyzed in a sequential gatekeeping procedure to prevent Type I error inflation. As such, the 100 mg endpoints were considered secondary to 200 mg endpoints. Headache pain free was defined as a reduction in headache severity from mild (1), moderate (2), or severe (3) at baseline to none (0). If a second dose was taken within 2 hours, the patient was considered to be a nonresponder to the first dose.

The key secondary efficacy endpoints were (1) a comparison between lasmiditan 200 mg and placebo of the proportion of patients who were MBS free at 2 hours after the first dose of study medication (MBS free was defined as a change from “yes” to “no” for the presence of the patient's baseline MBS [nausea, phonophobia, or photophobia]); (2) a comparison between lasmiditan 100 mg and placebo of the proportion of patients who were headache pain free at 2 hours after the first dose; and (3) a comparison between lasmiditan 100 mg and placebo of the proportion of patients who were MBS free at 2 hours after the first dose (all in the mITT population). For the primary and key secondary efficacy analyses, patients with missing data were assumed to be nonresponders.

Other secondary efficacy endpoints included comparisons between lasmiditan 200 mg/100 mg and placebo of the proportion of patients who were headache pain free and MBS free at other time points (in the mITT population); the proportion of patients with sustained pain freedom (defined as being headache pain free at 2 hours after the first dose and at the indicated assessment time, having not used any medications after the first dose) (mITT population); the proportion of patients with headache pain relief (defined as a reduction in headache severity from moderate [2] or severe [3] at baseline to mild [1] or none [0] or a reduction in headache severity from mild [1] at baseline, to none [0]); the proportion of patients who were free of migraine symptoms (vomiting, nausea, phonophobia, and photophobia); patient global impression of change; level of disability; and the proportion of patients who used a second dose of study drug for rescue or recurrence (all in the ITT population).

All primary and secondary efficacy analyses were made with a logistic regression model (Wald χ2 test), with treatment group and background use of migraine preventive medication as covariates. For treatment comparisons, an estimate of the odds ratio of achieving a response, as well as the corresponding confidence interval and p value with the Wald test, was computed. Exceptions to this were global impression of change and level of disability, which used a Cochran-Mantel-Haenszel test controlling for background use of migraine preventive medication. The primary and key secondary endpoints were tested at a 1-sided significance level of 0.025. A testing hierarchy was used to prevent type I error inflation for multiple comparisons: the primary efficacy endpoint was tested first, and if it was statistically significant, the key secondary efficacy endpoints were tested sequentially. Continuous variables were summarized with descriptive statistics; categorical variables were summarized with counts and percentages. Other secondary efficacy endpoints were tested at a 2-sided significance level of 0.05.

Results

Patients

A total of 2,231 patients were randomized, of whom 1,856 (83.2%) used the first dose of study drug and were included in the safety population (figure 1). Of these 1,856 treated patients, 1,805 (97.3%) completed the study, and 51 (2.7%) discontinued. Of the 375 patients who did not treat a migraine attack, 117 completed the study (generally having experienced no migraine or no eligible migraine), and 258 discontinued. Two patients discontinued the study due to an adverse event without having taken study drug, and thus were not part of the safety population or the ITT/mITT populations. Discontinuation rates were similar between treatment groups. The most common reasons for discontinuation were randomization failure (patients who were randomized but then deemed ineligible at the telephone confirmation), patient lost to follow-up, patient withdrew consent, and noncompliance with the protocol (figure 1).

Patient baseline demographic and clinical characteristics were similar between treatment groups (table 1). The majority of patients in the safety population were female (83.6%) and white (75.4%), and the mean age was 42.0 (SD 12.0) years. Overall, 1,445 patients (77.9%) had at least 1 cardiovascular risk factor in addition to migraine (table 1). A full list of cardiovascular risk factors is presented in table e-1 available from Dryad (doi.org/10.5061/dryad.s3p3m0d).

Table 1

Baseline demographic and clinical characteristics and characteristics of treated migraines

At baseline, patients had suffered from migraines for a mean duration of 19.3 (SD 12.9) years and had experienced a mean of 5.1 (SD 1.9) migraines per month in the past 3 months, and 32.0% had experienced migraine with aura. MIDAS total scores and history of headaches at baseline were generally similar across the treatment groups. Overall, the mean MIDAS total score was 31.5 (SD 22.2); patients had a mean of 17.4 (SD 10.6) days with headache in the past 3 months, with mean headache pain (scored from 0 [no pain at all] to 10 [pain as bad as it could be]) of 7.5 (SD 1.6).

Characteristics of treated migraines were similar between treatment groups (table 1). Photophobia was the most commonly reported symptom associated with the treated migraine and the most commonly reported MBS in each treatment group. Overall, among patients who reported an MBS, 53.8% selected photophobia, 24.2% selected nausea, and 22.0% selected phonophobia.

Efficacy

Statistically significantly more patients dosed with lasmiditan 200 mg (32.2%, p< 0.001, primary efficacy analysis) and lasmiditan 100 mg (28.2%, p< 0.001) were free of headache pain at 2 hours after the first dose compared with patients who received placebo (15.3%) (table 2). Superiority over placebo (p< 0.05) was noted after 1 hour in the lasmiditan 200 mg group and after 1.5 hours in the lasmiditan 100 mg group (figure 2A).

Similarly, statistically significantly more patients dosed with lasmiditan 200 mg (40.7%, p< 0.001, key secondary efficacy analysis) and lasmiditan 100 mg (40.9%, p< 0.001) were free of their MBS at 2 hours after the first dose compared with patients who received placebo (29.5%) (table 2). The proportion of MBS-free patients was greater than placebo (p< 0.05) from 0.5 hours on in both lasmiditan groups (figure 2B).

Considering the other secondary efficacy analyses, a greater proportion of patients in the lasmiditan 200 mg and lasmiditan 100 mg groups had headache relief at 2 hours than in the placebo group (table 2 and figure 2C). Lasmiditan also showed benefits over placebo (p< 0.05) at 2 hours in terms of the proportion of patients free of the migraine symptoms of phonophobia or photophobia (table 2) and in global impression of change and disability level ratings (table 3).

Table 3

Patient global impression of change and disability level by treatment group

Patients who received lasmiditan as a first dose were less likely to use a second dose of study drug than patients who received placebo as a first dose: 31.9% (177 of 555) of the lasmiditan 200 mg group, 39.0% (219 of 562) of the lasmiditan 100 mg group, and 59.9% (332 of 554) of the placebo group took a second dose between 2 and 24 hours after the first dose for rescue or recurrence (ITT population). Of these second doses, 676 were taken as rescue medication and 52 as recurrence medication.

Tolerability and safety

A total of 260 patients (42.7%) in the lasmiditan 200 mg group and 229 patients (36.3%) in the lasmiditan 100 mg group experienced at least 1 TEAE after the first dose compared with 101 patients (16.4%) in the placebo group (table 4). The majority of TEAEs were mild or moderate in intensity. TEAEs that occurred with an incidence of ≥2% in any lasmiditan group and greater than placebo were dizziness, fatigue, lethargy, nausea, paresthesia, and somnolence (table 4). No serious TEAEs related to study drug were reported, and no adverse events resulted in study discontinuation among those patients who used study drug. No patients showed suicidality, and there were no deaths during the treatment period. One patient died of an accidental overdose of methadone and oxycodone before taking the study drug.

View this table:
Table 4

Treatment-emergent adverse events (TEAEs) after the first dose

The incidence of cardiovascular TEAEs was low (table 4). After the first dose, the only cardiovascular TEAEs considered reasonably or possibly related to study drug were palpitations in 3 patients (0.5%) receiving lasmiditan 200 mg and 2 patients (0.3%) receiving lasmiditan 100 mg and bradycardia for 1 patient (0.2%) receiving lasmiditan 100 mg. A post hoc analysis of the incidence of TEAEs in patients with ≥2 cardiovascular risk factors at baseline is shown in table e-2 (available from Dryad, doi.org/10.5061/dryad.s3p3m0d); a similar pattern of TEAEs was observed in the full population.

There were no clinically meaningful differences in hematology, blood chemistry, urinalysis, vital signs, physical examination, or ECGs across treatment groups or with regard to changes from baseline.

Discussion

In this first phase 3, randomized, double-blind, placebo-controlled study of lasmiditan for the acute treatment of migraines, statistically significantly more patients who took lasmiditan (200 and 100 mg) experienced freedom from headache pain and MBS at 2 hours than patients who took placebo. These primary/key secondary outcomes were approved by the US FDA in a Special Protocol Assessment before the release of its draft guidance for studies of the acute treatment of migraines.22 Previously, migraine drugs needed to demonstrate statistically significant benefits for pain and all 3 associated symptoms (nausea, phonophobia and photophobia) to be granted approval by the FDA,22 despite a high proportion of patients not having nausea at baseline. The present study reports MBS as a major endpoint, an approach that reduces multiple comparisons and may improve statistical power to detect treatment effects. Individual associated symptoms were assessed as secondary endpoints and showed benefits for lasmiditan on phonophobia and photophobia but not nausea. Photophobia was the most commonly reported MBS at baseline, reported by more than half of patients, whereas nausea was the MBS for only around a quarter of patients. The use of patient-centric endpoints such as the MBS in clinical trials is important to allow meaningful benefits to the patient to be measured.

The outcomes were measured with real-time data captured by electronic diaries. The diaries did not allow retrospective data entry (each time point became available on the basis of the patient-recorded time of dosing and was available for ±5 minutes), offering an advantage over paper diaries. Of note, the placebo response rate for freedom from headache pain at 2 hours after dosing was higher in this study (15.3%) than in studies of oral triptans (generally <10%),23 which may be partly attributed to increased patient contact by the site (investigators were asked to call patients who did not feel well, who reported unusual symptoms, and who were not compliant).

Secondary analyses were supportive of the efficacy of lasmiditan. Rates of sustained pain freedom at 24 and 48 hours showed benefits for lasmiditan over placebo, but differences were smaller than expected, perhaps because of poor diary adherence at 24 hours. Patients who received lasmiditan as a first dose were less likely to take a second dose of study drug for rescue or recurrence than patients who received placebo as a first dose (31.9% of the lasmiditan 200 mg group, 39.0% of the lasmiditan 100 mg group, and 59.9% of the placebo group compared with 20%–34% in studies of oral triptans24).

Treatment with lasmiditan was generally well tolerated and safe. Adverse events were captured with the real-time electronic diaries: if the patients felt anything unusual since taking the study medication that they had not felt with a migraine before, this was recorded, and they were contacted by an investigator within 24 hours for further discussion. Adverse events were also discussed at the end-of-study visit. The incidence of TEAEs was higher in the lasmiditan 200 and 100 mg groups compared with the placebo group; however, the majority of TEAEs were mild or moderate in intensity. Activity limitations did not differ within treatment groups among those with treatment-emergent dizziness and those who did not have treatment-emergent dizziness. These data will be reported in detail separately. There were no deaths during the treatment period; no serious TEAEs related to study drug were reported; and no TEAEs resulted in discontinuation of the study among those patients who had used study drug. Most TEAEs were nervous system related, and the incidence of cardiovascular TEAEs with lasmiditan was low. Overall, the safety profile of lasmiditan was consistent with the phase 2 studies.14,25

Patients with cardiovascular risk factors and many stable forms of cardiovascular disease were eligible to participate in this clinical study, and the majority of patients (77.9%) had at least 1 cardiovascular risk factor at baseline. While no clinical trial is fully generalizable to clinical practice, the inclusion of patients with cardiovascular risk factors increases the generalizability of this study to real-world populations.

Lasmiditan dosed at 200 and at 100 mg was efficacious and well tolerated in the treatment of acute migraine among patients with a high level of cardiovascular risk factors.
