The American Registry for Migraine Research: Research Methods and Baseline Data for an Initial Patient Cohort.
The American Registry for Migraine Research (ARMR) is a multicenter, prospective, longitudinal patient registry, biorepository, and neuroimaging repository that collects clinical data, electronic health record (EHR) data, blood samples, and brain imaging data from individuals with migraine or other headache types. In this manuscript, we outline ARMR research methods and report baseline data describing an initial cohort of ARMR participants. ⋯ ARMR is a source of real-world patient data, biospecimens, and brain neuroimaging data that provides comprehensive insight into patients with migraine and other headache types being seen in headache specialty clinics in the United States. ARMR data will allow for longitudinal and advanced analytics that are expected to lead to a better characterization of patient heterogeneity, healthcare resource utilization, identification of endophenotypes, factors that predict treatment outcomes and clinical course, and ultimately advance the field toward precision headache medicine.

There is a significant unmet need for novel, effective, and well-tolerated acute migraine treatments. Remote electrical neuromodulation (REN) is a non-pharmacological, non-invasive, acute migraine treatment that stimulates upper arm peripheral nerves to induce conditioned pain modulation - an endogenous analgesic mechanism in which a conditioning stimulation inhibits pain in remote body regions. This review presents the method of action and the clinical data of REN and discusses its potential patient benefits. The clinically meaningful efficacy, together with a very favorable safety profile, suggests that REN may offer a promising alternative for the acute treatment of migraine and could be considered first-line treatment in some patients.

Randomized Controlled Trial
Evaluation of Cardiovascular Outcomes in Adult Patients With Episodic or Chronic Migraine Treated With Galcanezumab: Data From Three Phase 3, Randomized, Double-Blind, Placebo-Controlled EVOLVE-1, EVOLVE-2, and REGAIN Studies.
Blood pressure (BP), pulse, electrocardiogram (ECG), and clinical cardiovascular (CV) outcomes in patients with episodic or chronic migraine treated for up to 6 months with galcanezumab compared to placebo were evaluated. ⋯ In this 6-month treatment trial, the percentages of galcanezumab- and placebo-treated patients that reported CV TEAEs or serious adverse events were low and similar between groups with few discontinuations. Thus, no clinically meaningful treatment group differences were observed for changes in BP, pulse, or ECG parameters. Additional longer-term studies in a broader and larger cohort are required to better characterize CV safety.

Randomized Controlled Trial
Onset of Efficacy Following Oral Treatment With Lasmiditan for the Acute Treatment of Migraine: Integrated Results From 2 Randomized Double-Blind Placebo-Controlled Phase 3 Clinical Studies.
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. ⋯ 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.

Randomized Controlled Trial
A Randomized Phase 2 Study of Erenumab for the Prevention of Episodic Migraine in Japanese Adults.
A phase 2, double-blind, placebo-controlled study to evaluate the efficacy and safety of erenumab for the prevention of episodic migraine in Japanese patients was conducted. ⋯ Monthly subcutaneous injections of erenumab 70 mg demonstrated statistically significant and numerically maximal efficacy with a favorable safety profile, suggesting that erenumab is a potential new therapy for migraine prevention in Japan.
