Effect of a rescue or recurrence dose of lasmiditan on efficacy and safety in the acute treatment of migraine: Findings from the Phase 3 trials (SAMURAI and SPARTAN)

Abstract Background We studied the efficacy and safety of a second dose of lasmiditan for acute treatment of migraine. Methods SAMURAI and SPARTAN were double-blind, placebo-controlled Phase 3 studies in which individuals with migraine were randomized to oral lasmiditan 50mg (SPARTAN only), 100mg, 200mg, or placebo. Study drug was to be taken within 4 hours (h) of onset of a migraine attack (moderate or severe pain). A second dose of study drug was provided for rescue (patient not pain-free at 2h and took a second dose 2-24h post-first dose) or recurrence (patient pain-free at 2h, but experienced recurrence of mild, moderate, or severe migraine pain and took a second dose 2-24h after first dose). Randomization to second dose occurred at baseline; patients originally assigned lasmiditan were randomized to the same lasmiditan dose or placebo (2:1 ratio), and those originally assigned placebo received placebo. Data from SAMURAI and SPARTAN were pooled for efficacy and safety assessment of a second dose of lasmiditan. Results The proportion of patients taking a second dose was lower with lasmiditan versus placebo, and decreased with increasing lasmiditan dose; the majority who took a second dose did so for rescue. In patients taking lasmiditan as first dose, outcomes (pain free, most bothersome symptom [MBS] free) at 2h after a second dose for rescue were similar whether the second dose was lasmiditan or placebo (p>0.05 in all cases). In patients taking lasmiditan for first dose, outcomes at 2h after a second dose for recurrence were as follows: lasmiditan pooled versus placebo - pain free, 50% vs 32% (p>0.05); MBS free, 71% vs 41% (p=0.02); pain relief, 77% vs 52% (p=0.03). In patients whose first dose was lasmiditan, the incidence of treatment emergent adverse events (TEAEs) reported after the second dose was similar whether second dose was lasmiditan or placebo. Conclusions A second dose of lasmiditan showed some evidence of efficacy when taken for headache recurrence. There was no clear benefit of a second dose of lasmiditan for rescue treatment. The incidences of TEAEs were similar whether the second dose was lasmiditan or placebo.

Abstract Background Lasmiditan (LTN) is a selective 5-HT1F receptor agonist for the acute treatment of migraine in adults. We present detailed safety findings from the placebo-controlled, double-blind Phase 3 study, of LTN treatment across 4 attacks (CENTURION). Methods Patients were randomized 1:1:1 to LTN 200 mg (LTN200), LTN100, or a control group that received placebo for 3 attacks and LTN50 for either the 3rd or 4th attack (1:1). Safety analyses were conducted for patients who took ≥1 dose of study drug and, in some cases, those who took all 4 doses. Results Overall, 1471 patients treated 4494 attacks. The incidences of treatment-emergent serious adverse events (SAEs) were - placebo, n=2 (0.4 %); LTN100, n=1 (0.2 %); LTN200, n=2 (0.4 %); no specific treatment-emergent SAE was reported in more than one patient. The most common treatment emergent adverse events (TEAEs) with lasmiditan were dizziness, paresthesia, fatigue, nausea, vertigo, and somnolence; the vast majority were mild or moderate in severity. The incidences of these TEAEs were highest during the first attack and decreased during subsequent attacks. For patients who experienced a common TEAE with the first attack, less than 45 % experienced the same event in subsequent attacks. Patients who did not experience an event in the 1st attack infrequently experienced the same event in subsequent attacks. The time of onset of the common TEAE ranged from ~40 min to 1 h (dependent upon TEAE) and, for individual TEAE, the onset was similar across attacks. Duration was dependent upon TEAE and attack. It was shortest for paresthesia (< 2 h for all attacks); it ranged from 1.8 to 5.5 h for other common TEAEs and was generally similar across attacks. Serotonin syndrome was reported for 2 patients post LTN dosing; there were no meaningful differences across treatment groups in suicidality; there was no evidence of an increase in motor vehicle accidents. Conclusion In this blinded, controlled, multiple-attack study, LTN was associated with generally mild or moderate CNS-related TEAEs of short duration. TEAEs tended to decrease in frequency across the 4 attacks. Trial registration NCT03670810

Abstract Objective To evaluate the efficacy and safety of CT-P10, a rituximab biosimilar after a single switch, during a multinational, randomized, double-blind Phase 3 trial involving patients with RA. Methods Patients received 48 weeks’ treatment with CT-P10 or United States- or European Union-sourced reference rituximab (US-RTX and EU-RTX, respectively). Patients entering the extension period (weeks 48–72) remained on CT-P10 (CT-P10/CT-P10; n = 122) or US-RTX (US-RTX/US-RTX; n = 64), or switched to CT-P10 from US-RTX (US-RTX/CT-P10; n = 62) or EU-RTX (EU-RTX/CT-P10; n = 47) for an additional course. Efficacy endpoints included Disease Activity Score using 28 joints (DAS28), American College of Rheumatology (ACR) response rates, and quality of life-related parameters. Pharmacodynamics, immunogenicity and safety were also assessed. Results At week 72, similar improvements were observed by disease activity parameters including DAS28 and ACR response rate in the four extension period treatment groups. Quality of life improvements at week 72 vs baseline were similarly shown during the extension period in all groups. Newly developed anti-drug antibodies were detected in two patients following study drug infusion in the extension period. Similar pharmacodynamic and safety profiles were observed across groups. Conclusion Long-term use of CT-P10 up to 72 weeks was effective and well tolerated. Furthermore, switching from reference rituximab to CT-P10 in RA was well tolerated and did not result in any clinically meaningful differences in terms of efficacy, pharmacodynamics, immunogenicity and safety.

Sustained Responses

Background Sustained pain freedom is an important attribute of acute migraine therapies for patients and physicians. Here we report efficacy of the centrally penetrant, highly selective, 5-HT1F agonist lasmiditan on sustained pain freedom and other outcomes at 24 and 48 hours post-dose. Study design and methods Data from the similarly designed, Phase 3, double-blind studies SAMURAI (NCT02439320) and SPARTAN (NCT02605174) were pooled to more precisely estimate efficacy effects in these post-hoc analyses. In both studies, inclusion criteria were 3–8 migraine attacks per month and Migraine Disability Assessment Score of ≥ 11 (at least moderate disability). Patients were randomized equally to lasmiditan 200 mg, 100 mg, 50 mg (50 mg only in SPARTAN), or to placebo. The study drug was to be taken within 4 hours of onset of pain for non-improving headache of at least moderate severity. Sustained pain freedom was defined as being pain free at 2 hours and at the given time point (24 or 48 hours) post-dose without use of additional study drug or migraine medications. Sustained responses were assessed similarly for most bothersome symptom-free, total migraine-free, and disability-free outcomes. For comparisons with previously published data on other acute medications, an additional endpoint of modified sustained pain freedom at 24 hours was defined as being pain free at 2 hours and no moderate-to-severe headache at 24 hours post-dose without use of additional study drug or migraine medications. Results Significantly higher proportions of patients treated with lasmiditan versus placebo achieved headache pain freedom at 2 hours post-dose: 200 mg: 35.6%; 100 mg: 29.9%; 50 mg: 28.6%; placebo: 18.3% (all p < 0.001). Sustained pain freedom was significantly higher in patients treated with lasmiditan versus placebo at 24 hours: 200 mg: 21.2%; 100 mg: 16.9%; 50 mg: 17.4%; placebo: 10.3% (all p < 0.01); and at 48 hours: 200 mg: 18.4%; 100 mg: 15.2%; 50 mg: 14.9%; placebo: 9.6% (all p < 0.05). Similar sustained benefits of lasmiditan versus placebo at 24 and 48 hours were noted for most bothersome symptom-free, total migraine-free and disability-free responses. Modified sustained pain freedom at 24 hours was also observed in significantly higher proportions of lasmiditan-treated patients versus placebo: 200 mg: 27.0%; 100 mg: 21.7%; 50 mg: 21.7%; placebo: 12.9% (all p < 0.01). Conclusion Sustained responses at 24 and 48 hours were noted in significantly more patients treated with lasmiditan versus placebo for several efficacy outcomes including pain freedom, most bothersome symptom-free, total migraine-free and disability-free responses.

Abstract Background The clinical and economic burden of community-acquired bacterial pneumonia (CABP) is significant and is anticipated to increase as the population ages and pathogens become more resistant. Delafloxacin is a fluoroquinolone antibiotic approved in the United States for the treatment of adults with acute bacterial skin and skin structure infections. Delafloxacin’s shape and charge profile uniquely impacts its spectrum of activity and side effect profile. This phase 3 study compared the efficacy and safety of delafloxacin to moxifloxacin for the treatment of CABP. Methods A randomized, double-blind, comparator-controlled, multicenter, global Phase 3 study compared the efficacy and safety of delafloxacin 300 mg BID or moxifloxacin 400 mg QD in adults with CABP. The primary endpoint was early clinical response (ECR) defined as improvement at 96 (± 24) hours after first dose of study drug. Clinical response at test of cure (TOC) and microbiologic response were also assessed. Results In the intent-to-treat analysis population (ITT), ECR rates were 88.9% in the delafloxacin group and 89.0% in the moxifloxacin group. Noninferiority of delafloxacin compared with moxifloxacin was demonstrated. At TOC in the ITT population, the success rates were similar between groups. Treatment-emergent adverse events considered at least possibly related to the study drug occurred in 65 subjects (15.2%) in the delafloxacin group and 54 (12.6%) in the moxifloxacin group. Conclusions IV/oral delafloxacin monotherapy is effective and well tolerated in the treatment of adults with CABP, providing coverage for grampositive, gramnegative, and atypical pathogens.

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.
