Abstract
Migraine is a debilitating disease whose clinical and social impact is out of debate. Tolerability issues, interactions, contraindications, and inefficacy of the available medications make new options necessary. The calcitonin-gene-related peptide (CGRP) pathway has shown its importance in migraine pathophysiology and specific medications targeting this have become available. The first-generation CGRP receptor antagonists or gepants, have undergone clinical trials but their development was stopped because of hepatotoxicity. The new generation of gepants, however, are efficacious, safe, and well tolerated as per recent clinical trials. This led to the FDA-approval of rimegepant, ubrogepant, and atogepant. The clinical trials of the available gepants and some of the newer CGRP-antagonists are reviewed in this article.

Abstract
PURPOSE OF REVIEW Migraine is the second leading cause of years lived with disability after back pain. Poor tolerability, contraindications, drug-drug interactions and efficacy limited to a subpopulation make new approaches necessary for the acute and preventive treatment of migraine. The study of the calcitonin-gene-related peptide (CGRP) pathway over the last decades is a good example of translational medicine leading to directed therapies for patients. RECENT FINDINGS After some of the first-generation CGRP receptor antagonists, gepants, were not fully developed because of hepatotoxicity, the second generation of gepants have shown efficacy, safety and tolerability in recent clinical trials. SUMMARY Both rimegepant and ubrogepant have published positive randomized placebo-controlled clinical trials data. Vazegepant is the first intranasal gepant for the acute treatment of migraine and has announced a positive phase II/III study. Daily rimegepant use has preliminary data to suggest efficacy. Atogepant has shown efficacy in migraine prevention in a phase II/III study. Most importantly, hepatotoxicity has not been reported in specifically designed phase I studies or long-term extension studies, with rimegepant or ubrogepant, or in a preventive study with atogepant. Given the preventive effect, it seems likely that gepants will not lead to medication overuse headache. They will likely have no cardiovascular warnings. Because of the particular benefit gepants may represent for these groups of patients, specific studies in patients with medication overuse headache, as well as those with comorbid cardiovascular diseases, would be of considerable interest.

Abstract
More than 20 years have passed without the launch of a new substance class for acute migraine therapy. Triptans were the latest class of substances which successfully passed all developmental stages with a significant antimigraine efficacy and a sufficient safety profile. New drugs with a better adverse event profile and at least similar efficacy are needed for migraine subjects who cannot tolerate triptans for attack treatment. Lasmiditan is a novel highly specific 5-HT1F receptor agonist currently in clinical trials for acute migraine therapy and devoid of vasoconstriction in coronary arteries as determined in a surrogate assay. In both phase II randomized, placebo-controlled trials in acute migraine the primary endpoint was met. For the intravenous formulation a clear dose-dependent effect on headaches could be determined. Lasmiditan tablets in doses of 50-400 mg show significant headache relief after 2 hours compared with placebo and improved accompanying symptoms. This substance is chemically clearly different from other antimigraine drugs, which is also reflected by its dose-dependent adverse event profile chiefly including dizziness, vertigo, paresthesia and fatigue. Adverse events are usually linked to the central nervous system. Future phase III clinical trials with an active triptan comparator or in a preferential trial design will allow a better comparison of lasmiditan and triptans. They will also determine whether lasmiditan will become available to the migraine patient.

Abstract
BACKGROUND BMS-927711 is a potent, selective, competitive human calcitonin gene-related peptide (CGRP) receptor antagonist that has shown in vivo efficacy without vasoconstrictor effect. The objective of the current study was to determine an effective and tolerable dose range of BMS-927711 for the acute treatment of migraine. METHODS In this randomized, double-blind, placebo controlled, dose-ranging study, 885 patients were randomized using an adaptive design to one of the following dose groups: BMS-927711 (10, 25, 75, 150, 300, or 600 mg); sumatriptan 100 mg (active comparator); and placebo. Patients were treated for a single migraine attack. The primary endpoint was pain freedom at two hours post-dose. RESULTS Of patients who took the study drug, 799 had one post-randomization efficacy evaluation. Significantly more patients in the BMS-927711 75 mg (31.4%, P = 0.002), 150 mg (32.9%, P < 0.001), and 300 mg (29.7%, P = 0.002) groups and the sumatriptan group (35%, P < 0.001) had pain freedom at two hours post-dose versus placebo (15.3%). For the secondary endpoint of sustained pain freedom from two to 24 hours post-dose, BMS-927711 doses (25-600 mg) were also statistically significant compared with placebo. No deaths or treatment-related serious adverse events (AEs) were reported, and no patients discontinued because of AEs. CONCLUSIONS BMS-927711 is superior to placebo at several different doses (75 mg, 150 mg, and 300 mg) and has an excellent tolerability profile.

Abstract
Consider the problem of estimating a dose with a certain response rate. Many multistage dose-finding designs for this problem were originally developed for oncology studies where the mean dose-response is strictly increasing in dose. In non-oncology phase II dose-finding studies, the dose-response curve often plateaus in the range of interest, and there are several doses with the mean response equal to the target. In this case, it is usually of interest to find the lowest of these doses because higher doses might have higher adverse event rates. It is often desirable to compare the response rate at the estimated target dose with a placebo and/or active control. We investigate which of the several known dose-finding methods developed for oncology phase I trials is the most suitable when the dose-response curve plateaus. Some of the designs tend to spread the allocation among the doses on the plateau. Others, such as the continual reassessment method and the t-statistic design, concentrate allocation at one of the doses with the t-statistic design selecting the lowest dose on the plateau more frequently.

Abstract
INTRODUCTION Lasmiditan (COL-144; LY573144) is a novel, highly selective and potent agonist at 5-HT(1F) receptors that lacks vasoconstrictor activity. Preclinical and early clinical experiments predict acute antimigraine efficacy of COL-144 that is mediated through a non-vascular, primarily neural, mechanism. SUBJECTS AND METHODS In a randomised, multicentre, placebo-controlled, double-blind, group-sequential, adaptive treatment-assignment, proof-of-concept and dose-finding study, we treated 130 subjects in-hospital during a migraine attack. Subjects were allocated to an intravenous dose level of lasmiditan or placebo in small cohorts. The starting dose was 2.5 mg. Subsequent doses were adjusted, up or down, according to the safety and efficacy seen in the preceding cohort. The primary outcome measure was headache response defined as improvement from moderate or severe headache at baseline to mild or no headache at 2 h post-dose. The study was designed to explore the overall dose response relationship but was not powered to differentiate individual doses from placebo, nor to detect effect differences for other migraine symptoms. RESULTS Forty-two subjects received placebo and 88 received lasmiditan in doses of 2.5-45 mg. Subjects were observed in the clinic for 4 h after treatment and used a diary card to record symptoms and adverse events for up to 24 h. The study was terminated when the 20 mg dose met predefined efficacy stopping rules. Of subjects treated in the 10, 20, 30 and 45 mg lasmiditan dose groups, 54-75% showed a 2 h headache response, compared to 45% in the placebo group (P = 0.0126 for the linear association between response rates and dose levels). Patient global impression at 2 h and lack of need for rescue medication also showed statistically significant linear correlations with dose. Lasmiditan was generally well tolerated. Adverse events were reported by 65% of subjects on lasmiditan and by 43% on placebo and were generally mild. Dizziness, paresthesia and sensations of heaviness (usually limb) were more common on lasmiditan. CONCLUSIONS At intravenous doses of 20 mg and higher, lasmiditan proved effective in the acute treatment of migraine. Further studies to assess the optimal oral dose and full efficacy and tolerability profile are under way. The non-vascular, neural mechanism of action of lasmiditan may offer an alternative means to treat migraine especially in patients who have contra-indications for agents with vasoconstrictor activity. The clinicaltrials.gov identifier for this study is NCT00384774.

Abstract
There is an obvious need to improve clinical trial designs with respect to efficiency, duration and the number of patients recruited. Adaptive (flexible) designs may be valuable in this respect. We simulated the properties of a two-stage adaptive proof-of-concept and dose-finding trial design in adult migraine patients with moderate to severe headache, with or without aura. We also assessed the usefulness of a combined Bayesian and frequentist approach in the estimation of the probability of success of subsequent Phase III studies. Applying such an innovative approach would result in a reduction of the required sample size by 30 patients and no prolongation of the trial duration. The probability of success in Phase III is > 81%. An innovative adaptive design can facilitate testing of investigational migraine medications by reducing patient numbers and improving predictivity of success in Phase III.

Abstract
Migraine is a common disabling brain disorder that--considering its clinical and economic impact--is understudied and in need of additional management options. Currently, treatments are classified as preventive or acute-attack therapies, although it is expected that this distinction will become blurred over time. The gap-junction blocker tonabersat, an inducible nitric oxide synthase (NOS) inhibitor and botulinum toxin A are all being investigated in clinical trials as preventive therapies. Device-based approaches using neurostimulation of the occipital nerve have provided promising results, whereas the first study of patent foramen ovale closure for migraine prevention produced disappointing results. Calcitonin gene-related peptide receptor antagonists, vanilloid TRPV1 receptor antagonists and NOS inhibitors are all being investigated in clinical trials for acute migraine. There is much cause for optimism in this area of neurology and considerable benefit awaits our patients.

Abstract
Pharmacokinetics (PK) of the calcitonin gene-related (CGRP) peptide receptor antagonist BIBN 4096 BS, the first compound of this new class tested in humans, has been evaluated combining the data from a phase I study performed in healthy volunteers and a phase IIa study conducted in migraine patients. A total of 94 individuals with a total of 556 plasma samples contributed to the analysis. Subjects received a single dose of 0.25, 0.5, 1, 2.5, 5 or 10 mg BIBN 4096 BS administered in a 10 min i.v. infusion. Blood samples were obtained at selected times up to 12 h. Disposition of BIBN 4096 BS was best described with a three compartment body model with first order elimination. BIBN 4096 BS showed a moderate degree (between 30 and 50%) of inter-subject variability in the apparent volume of distribution of the central compartment (V1), total plasma clearance (CL), distribution clearance between the central and deep compartment, and the apparent volume of distribution of the shallow compartment. Typical estimates of V1 were significantly (P <0.01) lower in healthy volunteers (7.16 versus 9.95 L), and typical estimates of CL were significantly lower in subjects receiving oral contraceptives (11.4 versus 17.1 L/h), although the absolute reduction in the unexplained inter-subject variability was negligible (4%). Computer simulations showed that the above mentioned covariates lack clinical significance. In conclusion, the pharmacokinetics of BIBN 4096 BS was independent of the dose and not altered by the tested covariates to a clinically significant degree.
