Long-Term Efficacy and Safety of Ravulizumab in Adults With Anti-Acetylcholine Receptor Antibody-Positive Generalized Myasthenia Gravis: Final Results From the Phase 3 CHAMPION MG Open-Label Extension.
Trial report in European journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 24 papers, 4 of them syntheses 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
backgroundRavulizumab, an anti-complement C5 monoclonal antibody, was efficacious with acceptable safety in the randomized controlled period (RCP) and interim open-label extension (OLE) periods of the CHAMPION MG phase 3 trial in adults with anti-acetylcholine receptor antibody-positive (AChR-Ab+) generalized myasthenia gravis (gMG). Here, we report final results from the OLE.
methodsPatients who completed the 26-week RCP could enter the OLE and receive ravulizumab for up to 4 years. Efficacy and safety were assessed throughout the OLE.
resultsAmong all ravulizumab-treated patients (n = 169; median [range] ravulizumab treatment, 759.0 [14.0, 1265.0] days), 161 entered the OLE (ravulizumab-ravulizumab: n = 78; placebo-ravulizumab: n = 83). Sustained improvements were observed in Myasthenia Gravis Activities of Daily Living (MG-ADL) total scores (ravulizumab-ravulizumab, least squares mean [95% CI] change from RCP baseline at week 164: -4.0 [-5.3, -2.8]; p < 0.0001; placebo-ravulizumab, change from OLE baseline after 138 weeks of treatment: -2.1 [-3.3, -0.9]; p = 0.0005). One hundred and forty-one out of 160 (88.1%) patients achieved a ≥ 2-point improvement in MG-ADL total score, and 59/141 (41.8%) achieved a score of 0 or 1; once achieved, 32/59 (54.2%) sustained this status for > 50% of their remaining time in the study. Similar improvements were observed in Quantitative Myasthenia Gravis and Myasthenia Gravis Quality of Life-15 revised scores, and Neurological Quality of Life Fatigue subscale scores. Clinical deterioration event rates were reduced in the OLE versus placebo in the RCP. Corticosteroid usage was reduced in the OLE. Ravulizumab was well tolerated; no meningococcal infections were reported.
conclusionRavulizumab demonstrated clinically meaningful and durable efficacy and safety in adults with AChR-Ab+ gMG.
