Randomized Controlled Trial Multicenter Study
Safety of galcanezumab in patients with episodic migraine: A randomized placebo-controlled dose-ranging Phase 2b study.
Background Safety findings from a Phase 2b study of galcanezumab, a humanized monoclonal antibody against calcitonin gene-related peptide, for prevention of migraine (NCT02163993) are reported here. Methods Patients aged 18-65 years with episodic migraine were evaluated in this multicenter, double-blind, randomized study. After randomization, 410 patients were administered 5, 50, 120 or 300 mg of galcanezumab or placebo subcutaneously once every 4 weeks for 12 weeks, followed by a post-treatment off-drug period lasting 12 weeks. ⋯ Potential hypersensitivity events were reported at similar frequencies in galcanezumab (3.3%) and placebo (5.1%) groups. Incidence of treatment-emergent anti-drug antibodies in galcanezumab dose groups (4.6% of patients during treatment period) did not appear to have any meaningful effects on safety, the pharmacokinetics of galcanezumab, or its ability to bind to the target ligand. Conclusion The results from this 3-month Phase 2b study support the initiation of larger Phase 3 trials of longer duration.

Randomized Controlled Trial
ARISE: A Phase 3 randomized trial of erenumab for episodic migraine.
Background Calcitonin gene-related peptide plays an important role in migraine pathophysiology. Erenumab, a human monoclonal antibody that inhibits the calcitonin gene-related peptide receptor, is being evaluated for migraine prevention. Methods In this randomized, double-blind, placebo-controlled, phase 3 study, 577 adults with episodic migraine were randomized to placebo or 70 mg erenumab; 570 patients were included in efficacy analyses. ⋯ Most frequent adverse events were upper respiratory tract infection, injection site pain, and nasopharyngitis. Conclusions As a preventive treatment of episodic migraine, erenumab at a dosage of 70 mg monthly significantly reduced migraine frequency and acute migraine-specific medication use.

Multicenter Study Observational Study
A multicenter, prospective, single arm, open label, observational study of sTMS for migraine prevention (ESPOUSE Study).
Objective To evaluate the efficacy and tolerability of single pulse transcranial magnetic stimulation (sTMS) for the preventive treatment of migraine. Background sTMS was originally developed for the acute treatment of migraine with aura. Open label experience has suggested a preventive benefit. ⋯ There were no serious adverse events. Conclusions This open label study suggests that sTMS may be an effective, well-tolerated treatment option for migraine prevention. Trial registration number NCT02357381.
