Reports from this year’s annual scientific meeting of the American Headache Society in San Diego, USA, and online (13-16 June 2024), include recent progress towards precision medicine for migraine, concerning data about patient groups that miss out on anti-CGRP therapies, CGRP mAb trial results in cluster headache, and cortical changes following CGRP mAb therapy.
A machine learning model developed by researchers at a US tertiary headache centre can accurately predict response to CGRP mAbs nearly 80% of the time. A deep neural network, TabNet, was trained using 145 variables based on results of questionnaires completed by 4260 adult patients with migraine during their initial and follow up headache consultations …

These were the main findings of the Phase 3, placebo controlled ALLEVIATE trial (NCT04688775) of eptinezumab 400 mg i.v in 231 patients with eCH.1 Over …

Read more »Reductions in cortical thickness and decreased functional connectivity seen in patients with migraine who respond to CGRP mAbs may indicate recovery from maladaptive neural activity in the visual, sensory and pain regions and normalisation of the hyperreactive/hyperexcitable state seen in migraine. This was the conclusion of Dr Edina Szabo from Beth Israel Deaconess Medical Center …

In the study, intraperitoneal injections of clodronate liposomes (150 μL, IP) to deplete macrophages, or the …
