Effects of Lasmiditan on Cardiovascular Parameters and Pharmacokinetics in Healthy Subjects Receiving Oral Doses of Propranolol

Investigation of the Effect of Lasmiditan on the Pharmacokinetics of P-Glycoprotein and Breast Cancer Resistance Protein Substrates

Lasmiditan is an in vitro inhibitor of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) efflux transporters. We aimed to confirm predictions from physiologically based pharmacokinetic models of lasmiditan, and assess the safety and tolerability of rosuvastatin and dabigatran co-administered with lasmiditan. In this open-label, post-marketing drug-drug interaction, phase 1 clinical trial, eligible participants were adults aged 21-70 years with a body mass index of 18.5-35.0 kg/m2 . Part 1 (P-gp, 150 mg dabigatran etexilate with 200 mg lasmiditan) and part 2 (BCRP, 10 mg rosuvastatin with 200 mg lasmiditan) employed similar designs: a single dose of probe substrate administered on day -2 with pharmacokinetic evaluation; 1-week washout; lasmiditan administered on days 8 and 9 alone; lasmiditan co-administered with a single dose of probe substrate on day 10, with pharmacokinetic evaluation of probe substrate and lasmiditan. Sixty-six participants were included in part 1 and 30 participants were included in part 2. Following dabigatran co-administration with lasmiditan, versus dabigatran alone, 90% confidence intervals for geometric least-squares (LS) mean ratios of area under the plasma concentration-time curve from time 0 extrapolated to infinity (AUC0-∞ ) and maximum observed drug concentration (Cmax ) were not contained within the non-effect boundaries (0.80 to 1.25). Dabigatran AUC0-∞ increased by 25% and Cmax increased by 22%. The median time of maximum observed drug concentration (tmax ) for dabigatran was 2.0 to 3.0 hours. Following rosuvastatin co-administration with lasmiditan, versus rosuvastatin alone, 90%CIs for geometric LS mean ratios of AUC0-∞ and Cmax were contained within non-effect boundaries (0.80-1.25). Rosuvastatin AUC0-∞ increased by 15% and Cmax increased by 7%. The median tmax for rosuvastatin was 4.0 hours. Results suggest that lasmiditan has a weak effect on P-gp substrates and no clinically relevant effect on BCRP substrates.

The 5-HT1F receptor as the target of ditans in migraine - from bench to bedside

Migraine is a leading cause of disability in more than one billion people worldwide, yet it remains universally underappreciated, even by individuals with the condition. Among other shortcomings, current treatments (often repurposed agents) have limited efficacy and potential adverse effects, leading to low treatment adherence. After the introduction of agents that target the calcitonin gene-related peptide pathway, another new drug class, the ditans - a group of selective serotonin 5-HT_1F receptor agonists - has just reached the international market. Here, we review preclinical studies from the late 1990s and more recent clinical research that contributed to the development of the ditans and led to their approval for acute migraine treatment by the US Food and Drug Administration and the European Medicines Agency.

Cardiovascular Disease and Migraine: Are the New Treatments Safe?

PURPOSE OF REVIEW

The authors present data on cardiovascular safety for the new acute and preventive migraine treatments including ditans, gepants, and calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) alongside older medications like triptans and ergotamines.

RECENT FINDINGS

The authors conclude that there are no cardiovascular safety concerns for lasmiditan, and that it could be used in those with cardiovascular disease. In fact, the literature even suggests that triptans are safer in cardiovascular disease than their contraindications may suggest. At this time, there is insufficient evidence that gepants and CGRP mAbs should be contraindicated in those with cardiovascular disease including stroke or myocardial infarction, though erenumab has now been associated with hypertension. Vasodilation may be an important CGRP-mediated mechanism mid-ischemia especially in patients with small vessel disease; hence, CGRP antagonists should be use with caution in this context. Long-term data is still needed, and prescribers should ensure patients are aware of the limitations of our knowledge at this time, while still offering these effective and well-tolerated treatment options.

Drug Safety in Episodic Migraine Management in Adults Part 1: Acute Treatments

PURPOSE OF REVIEW

The aim of this review is to aid in choosing safe options when assessing potential risks of acute migraine treatments based on known mechanisms of action and anticipated safety concerns.

RECENT FINDINGS

Part 1 highlights safety issues associated with commonly used medications to treat acute migraine attacks. Strategies to mitigate cardiovascular and gastrointestinal risks of nonsteroidal anti-inflammatory drugs, evaluation of cardiovascular risks of triptan and ergot alkaloids, and precautions with use of antiemetics and the novel drugs gepants and ditans are discussed to help practitioners in clinical decision-making. When available, we included recommendations from professional societies and data from pharmacovigilance systems. While guidelines on efficacy are available, one must also consider the possible risks and adverse effects of a drug when creating treatment plans.

Lasmiditan: Acute Migraine Treatment Without Vasoconstriction. A Review

Objective: To review the efficacy and safety of the newly Food and Drug Administration approved drug lasmiditan, and its place in therapy in the treatment of acute migraine attacks. Data Sources: A literature search of Web of Science, PubMed, and Google Scholar was preformed (September 1999 to May 2021) using the following search terms: acute migraine treatment, triptans, lasmiditan, Reyvow, Rimegepant, Nurtec, Ubrogepant, Ubrelvy, migraine, vasoconstriction, and cardiovascular risk. Product labeling, https://www.clinicaltriasl.gov, and product monographs were also reviewed. Study Selection and Data Extraction: Relevant English-language studies were considered. Data Synthesis: Lasmiditan is the first in its class approved for acute migraine treatment. Lasmiditan exerts its therapeutic effect through agonism at the 5-HT_1F receptor, which has been shown to produce no vasoconstriction in preclinical models. Relevance to Patient Care and Clinical Practice: It is both scientifically and clinically relevant to review lasmiditan and determine the value of an acute migraine drug that does not induce vasoconstriction. Patients with preexisting cardiovascular conditions for which current migraine therapy is contraindicated may benefit from therapeutic use of lasmiditan. However, the potential cardiovascular benefit needs to be weighed against the increased central nervous system risks observed with lasmiditan. Conclusions: Lasmiditan is an oral tablet drug that is used for acute migraine abortive treatment and data suggest that it does not induce vasoconstriction, a common side effect often observed with the current first-line abortive migraine treatment drug class, triptans. This is especially important in acute migraine patients with cardiovascular risk factors in which triptan use is contraindicated.

Safety and Risk of Medication Overuse Headache in Lasmiditan and Second-Generation Gepants: A Rapid Review

The treatment of migraine is often complicated by insufficient headache relief, a miscellany of side effects and the risk of developing Medication Overuse Headache (MOH). Novel acute therapies have been recently developed and are now in the early post-marketing phase. Lasmiditan is a highly selective serotonin receptor agonist that binds to the 5-HT_1F receptor, while ubrogepant and rimegepant antagonize the calcitonin gene-related peptide receptor. All three medications are now prescribed in a real-world setting, and an adequate level of knowledge is the starting point for rational use. In this rapid systematic review, we have established what is known about lasmiditan, ubrogepant and rimegepant, highlighting the most relevant safety aspects available from published studies and speculating about their risk of MOH.

Efficacy and Safety of Lasmiditan for Acute Treatment of Migraine in Adults: A Meta-Analysis

Monotherapy with triptans in acute migraine is ineffective in many patients and contraindicated in certain cardiovascular diseases where alternative therapeutic options are necessary to explore. This meta-analysis has evaluated the efficacy and safety of lasmiditan for the treatment of acute migraine in adults. After performing a literature search on MEDLINE/PubMed, Scopus, Cochrane databases, and International Clinical Trial Registry Platform, reviewers assessed eligibility and extracted data from 4 relevant articles. Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed in the selection, analysis, and reporting of findings. A random-effects model was used to estimate effect size. Quality assessment was done using the risk of bias assessment tool and meta-regression for probable variables affecting effect size. Subgroup analysis was done depending on the dose of lasmiditan. Lasmiditan use was associated with a significantly higher percentage of patients with pain freedom (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.72-2.39; P < .00001), sustained pain freedom (OR, 1.93; 95%CI, 1.55-2.39; P <.00001), headache response (OR, 2.05; 95%CI, 1.77-2.36; P < .00001), clinical disability level (OR, 1.36; 95%CI, 1.20-1.55; P < .00001), patients' global impression (OR, 1.88; 95%CI, 1.69-2.10; P < .00001), and significantly lower use of rescue medication (OR, 0.49; 95%CI, 0.38-0.63; P < .00001) compared to placebo. Lasmiditan use was also associated with a higher likelihood of adverse effects like dizziness (OR, 6.54; 95%CI, 4.24-10.07; P < .00001), paresthesia (OR, 4.28; 95%CI, 2.97-6.17; P < .00001), and fatigue (OR, 5.67; 95%CI, 3.78-8.52; P < .00001) compared to placebo. Subgroup analysis showed a dose-dependent effect of lasmiditan on pain freedom, sustained pain freedom, patient's global impression, and occurrence of adverse drug reactions. Prediction probability for effect estimate favoring placebo was calculated to be 0.0017%. Lasmiditan has shown a favorable effect in terms of efficacy and safety in the treatment of an acute attack of migraine in comparison to placebo. Further studies are needed to evaluate long-term safety, efficacy, and use in specific subgroups of patients. PROSPERO Registration Number: CRD42020177838.

Novel Therapies in Acute Migraine Management: Small-Molecule Calcitonin Gene-Receptor Antagonists and Serotonin 1F Receptor Agonist

OBJECTIVE

To review the efficacy, safety, and cost of 3 newly approved agents-ubrogepant, lasmiditan, and rimegepant-representing 2 therapeutic classes, calcitonin gene-related peptide (CGRP) receptor antagonist and serotonin 1F (5-HT1F) agonists, for the acute treatment of migraine with or without aura.

DATA SOURCES

The Institute of Health US National Library of Medicine Clinical Trials, PubMed, and Cochrane databases were queried. Abstracts, journal articles, and other relevant sources published or present were reviewed. Search terms included the following: ubrogepant, MK-1602, Ubrelvy®, rimegepant, Nurtec®, BHV-3000, BMS-927711, lasmiditan, Reyvow®, LY573144.

STUDY SELECTION AND DATA EXTRACTION

Relevant English-language articles from June 30, 2010, to August 31, 2020, were evaluated and included in the narrative.

DATA SYNTHESIS

CGRP receptor antagonists, ubrogepant and rimegepant, achieved 2-hour pain freedom and freedom from the most bothersome migraine symptom (MBS) at 2 hours. Both agents were well tolerated, with adverse effects similar to placebo. Lasmiditan, a 5-HT1F receptor antagonist, also improved 2-hour pain freedom and freedom from the MBS at 2 hours. Lasmiditan is associated with dizziness, paresthesia, somnolence, nausea, fatigue, and lethargy.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

Ubrogepant, rimegepant, and lasmiditan represent a new and exciting chapter in acute migraine therapy. To date, no head-to-head studies have compared these agents with the triptans. Ubrogepant and lasmiditan are effective in triptan nonresponders. None of the 3 agents is contraindicated in cardiovascular disease, unlike the triptans.

CONCLUSIONS

Based on available data, ubrogepant, rimegepant, and lasmiditan should be reserved as second-line therapy and may be safe in patients with cardiovascular risk. Lasmiditan's adverse effect profile may limit its use.

Lasmiditan: an additional therapeutic option for the acute treatment of migraine

Introduction: Migraine is currently listed as the second cause of 'years lived with disability' and the sixth cause of global disability. Despite the burden associated to the disease, availability of specific drugs is still limited.Areas covered: The authors have evaluated lasmiditan, the first 'ditan' approved by the Food and Drugs Administration in 2019, from a global perspective: basic chemistry, pharmacodynamic and pharmacokinetic profiles, efficacy in migraine as a 5-HT_1F receptor selective agonist, tolerability and clinical safety, and impact on migraine-related disability. Our evaluation considered original papers and review articles published from 2010 to 2020.Expert opinion: Available data point to the efficacy of lasmiditan in reducing migraine pain and the most bothersome symptoms within 2 hours from oral administration. Moreover, lasmiditan has a positive effect on migraine-related disability. Its side effects mostly reflect an involvement of the central nervous system or the vestibular system, while cardiovascular side effects are rare and mild.Lasmiditan can be safely prescribed in patients who have failed non-steroid anti-inflammatory drugs or triptans or with cardiovascular risk factors. Caution is advised in frequent users, due to lack of reliable data on its abuse potential. Further data are necessary to determine the usability of lasmiditan in particular populations, e.g. children and adolescents, pregnancy.

Lasmiditan for the acute treatment of migraine

Migraine is a leading cause of morbidity and disability worldwide. Triptans were the first migraine-specific drug class developed and have proven efficacy in treatment of this neurological disease. They are however contraindicated in patients with cardiovascular disease and possibly others, owning to their vasoconstrictive properties. This review will focus on lasmiditan, which has been called the first 'ditan' and 'neurally acting anti-migraine agent', designed to selectively agonize the serotonin 5-HT_1F receptor subtype, providing anti-migraine effects without concomitant vasoconstriction. To date, lasmiditan has proven safe and effective for the acute treatment of migraine in two Phase II and four Phase III trials. Post hoc analysis revealed that the majority of treatment-emergent adverse events were CNS-related, mild-to-moderate in severity and self-limiting. The US FDA label recommends that patients not drive or operate machinery until at least 8 h after taking each dose of lasmiditan.

Rational Use of Lasmiditan for Acute Migraine Treatment in Adults: A Narrative Review

PURPOSE

This narrative review provides an update on the research that led to the development of ditans and lasmiditan for the acute treatment of migraine in adults and discusses the potential advantages and disadvantages of lasmiditan in clinical use.

METHODS

The electronic databases PubMed, Scopus, and ClinicalTrials.gov were searched from database inception through January 9, 2021, to identify relevant studies. Search results were assessed for their overall relevance to this review.

FINDINGS

Because part of the effect of the triptans is mediated by the serotonin 1F receptors, which are not present in the smooth muscle, a pure agonist of these receptors, lasmiditan, was developed. Lasmiditan is hypothesized to act on antinociceptive pathways and inhibit the calcitonin gene-related peptide release. Lasmiditan was approved by the US Food and Drug Administration in 2019 based on the results of 2 pivotal trials that found a significant difference from placebo in the percentage of patients who achieved freedom from pain and most bothersome symptom at 2 h. The main concern of lasmiditan derives from its central nervous system-related adverse effects, mainly dizziness and paraesthesia, probably attributable to its high blood brain barrier penetration. These central nervous system adverse effects impair driving performance for hours and might be suboptimal for individuals with migraine who want to quickly stop the migraine attack to resume their activities as soon as possible.

IMPLICATIONS

Despite the advantage of being beneficial in the acute treatment of migraine without vasocostrictive action, lasmiditan also presents limitations, in particular the central nervous system adverse effects. Moreover, head-to-head trials against triptans and gepants are indispensable to determine the better option for patients.

Pharmacokinetics, Safety, and Tolerability of Lasmiditan in Pediatric Patients with Migraine

Introduction

Lasmiditan is a selective serotonin (5-HT1F) receptor agonist approved in the US for the acute treatment ofmigraine in adults. This phase I, open-label, two-cohort study assessed the pharmacokinetics (PK), safety, and tolerability of lasmiditan in patients with migraine aged 6 to < 18 years.

Methods

Cohort 1 (15 to ≤ 40 kg) and Cohort 2 (> 40 to ≤ 55 kg) received single oral doses of lasmiditan (100 mg and 200 mg, respectively).Blood samples for the assessment of PK and safety parameters were collected over a 24-h period. Follow-up was approximately 14 days after dosing.

Results

Eighteen patients received lasmiditan (11 in Cohort 1, 7 in Cohort 2) and 17 patients completed the study. One patient in Cohort 2 discontinued due to adverse events. Plasma concentrations peaked at 1.5–2 h post dose and then declined, with a terminal half-life of approximately 4 h in both cohorts. While the exposure to lasmiditan was generally similar between cohorts, PK parameters, such as apparent total body clearance and volume of distribution, were greater for the 200 mg cohort relative to the 100 mg cohort. No deaths or serious adverse events were reported. The frequency and severity of adverse events (including somnolence, dizziness, and fatigue) were generally mild and similar to those in adult studies.

Conclusion:

The PK results support weight-based dosing of lasmiditan in pediatric patients with migraine and no new safety or tolerability issues were identified. These findings support further investigation of lasmiditan as a potential treatment in pediatric patients with migraine.

Pharmacokinetics, Pharmacodynamics and Drug-Drug Interactions of New Anti-Migraine Drugs-Lasmiditan, Gepants, and Calcitonin-Gene-Related Peptide (CGRP) Receptor Monoclonal Antibodies

In the last few years, there have been significant advances in migraine management and prevention. Lasmiditan, ubrogepant, rimegepant and monoclonal antibodies (erenumab, fremanezumab, galcanezumab, and eptinezumab) are new drugs that were launched on the US pharmaceutical market; some of them also in Europe. This publication reviews the available worldwide references on the safety of these anti-migraine drugs with a focus on the possible drug–drug (DDI) or drug–food interactions. As is known, bioavailability of a drug and, hence, its pharmacological efficacy depend on its pharmacokinetics and pharmacodynamics, which may be altered by drug interactions. This paper discusses the interactions of gepants and lasmiditan with, i.a., serotonergic drugs, CYP3A4 inhibitors, and inducers or breast cancer resistant protein (BCRP) and P-glycoprotein (P-gp) inhibitors. In the case of monoclonal antibodies, the issue of pharmacodynamic interactions related to the modulation of the immune system functions was addressed. It also focuses on the effect of monoclonal antibodies on expression of class Fc gamma receptors (FcγR).

The potential of lasmiditan in migraine

Lasmiditan, a highly selective 5-hydroxytryptamine receptor 1F (5-HT_1F) agonist, is the first drug in its class and is lacking triptan-like vasoactive properties. The US Food and Drug Administration (FDA) has recently approved lasmiditan for the acute treatment of migraine in adults based on positive results of two pivotal phase III trials, which showed a significant difference to placebo in the proportion of patients achieving total migraine freedom within 2 h. More patients with lasmiditan achieved headache freedom and, in addition, freedom from the most bothersome symptom, that is, photophobia, than with placebo. Treatment-related side effects seem to be related to the rapid penetration of the drug into the brain and include dizziness, paresthesia and drowsiness, mostly of mild to moderate intensity. Interim results from an ongoing long-term phase III trial suggest a decrease in the frequency of adverse events after multiple lasmiditan use. Lasmiditan is a promising acute anti-migraine therapy, in particular for patients with cardiovascular risk factors, contraindications, or unwanted side effects to triptans.

Lasmiditan for Acute Treatment of Migraine in Adults: A Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

The US Food and Drug Administration has approved orally administered 100-mg and 200-mg doses of lasmiditan for the acute treatment of migraine, with or without aura. Having a unique mechanism of action, lasmiditan is the first and only Food and Drug Administration-approved serotonin 5-HT_1F receptor agonist.

OBJECTIVE

The objective of this study was to systematically evaluate the efficacy and safety of lasmiditan for the acute treatment of migraine in adult patients.

METHODS

We systematically searched PUBMED, EMBASE, and Cochrane Library databases. Any relevant articles published before 3 March, 2020 were collected. Inclusion criteria were: (1) randomized clinical trials; (2) enrolled adult participants diagnosed with migraine; (3) compared lasmiditan at 100 mg or 200 mg with placebo; (4) enrolled more than 100 participants; and (5) provided any available data for predefined primary or secondary outcomes.

RESULTS

Three high-quality, multi-centered randomized clinical trials with 4506 patients in total were included. We found that the use of lasmiditan was related to a significantly increased rate of pain freedom at 2 h post-dose with 31.60% patients achieving freedom of pain in the lasmiditan group compared with 17.55% patients in the placebo group (relative risk [RR] 1.80 [95% confidence interval (CI) 1.34-2.42]), with no significant heterogeneity. In addition, lasmiditan is reported to significantly increase the rate of absence of the most bothersome symptoms at 2 h compared with the placebo group with no significant heterogeneity (lasmiditan, 42.82%; placebo, 30.38%; RR 1.44 [95% CI 1.03-2.01], I² = 0%). With regard to the safety endpoints, compared with the placebo group, participants in the lasmiditan group had a higher rate of fatigue, paresthesia, and somnolence (fatigue: lasmiditan, 1.94%; placebo, 0.24%; RR 7.96 [95% CI 0.4-158.86]; paresthesia: lasmiditan, 6.91%; placebo, 1.56%; RR 4.46 [95% CI 1.54-12.93], somnolence: lasmiditan, 5.9%; placebo, 2.15%; RR 2.76 [95% CI, 1.49-5.11]) with low heterogeneity. A subgroup analysis demonstrated that without safety differences, participants who received the 200-mg dose had a higher percentage of freedom of pain at 2 h and sustained pain relief at 2-24 h compared with the 100-mg dose (freedom of pain at 2 h: lasmiditan, 34.53%; placebo, 28.67%; RR 1.2 [95% CI 1.04-1.38]; lasmiditan, 20.62%; placebo, 16.33%; RR 1.26 [95% CI 1.19-1.34]), with low heterogeneity for both outcomes (I² = 0%).

CONCLUSIONS

In this meta-analysis, the use of lasmiditan as an acute treatment for episodic migraine in adults led to a greater percentage of freedom of pain and the absence of the most bothersome symptoms at 2 h post-dose. Lasmiditan 200 mg had superior efficacy to 100-mg dose without a significantly increased risk for adverse events.
