Fremanezumab and Non-High-Dose Galcanezumab for Comorbid Cluster Headache in Patients with Migraine: Three Cases.
Article in Neurology international, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A new treatment option for cluster headache (CH) prevention is needed. Monoclonal antibodies (mABs) against calcitonin gene-related peptide (CGRP) ligands are used as a preventative treatment for migraine. Considering the CGRP's role in the CH attack's ignition and upkeep, fremanezumab and galcanezumab have been evaluated for CH preventative treatment. However, only high-dose (300 mg) galcanezumab has been approved for episodic CH prevention. We herein report three cases of migraine and comorbid CH with previous failures of preventive treatments. Two cases were treated with fremanezumab and one with non-high-dose galcanezumab. All three cases showed good results, not only for migraine, but also for CH attacks. This report suggests the efficacy of CGRP-mABs for CH prevention. Our cases differed from cases in the phase 3 trials of CGRP-mABs for CH prevention in two ways: first, our patients had both migraine and comorbid CH, and second, we used a combination of CGRP-mABs with preventative drugs, such as verapamil and/or prednisolone, to treat CH. Future accumulation of real-world data may prove the efficacy of CGRP-mABs for CH prevention.
