First analysis of the Myasthenia Gravis SPOTLIGHT Registry: outcomes with eculizumab and ravulizumab
Bibliographic record
Abstract
BACKGROUND: Complement component 5 inhibitors are indicated for the treatment of anti-acetylcholine receptor antibody-positive generalized myasthenia gravis (gMG). Clinical trials have demonstrated improved functional ability, muscle strength, and quality of life (QOL) in patients treated with eculizumab or ravulizumab. Evidence for their effectiveness and safety in clinical practice is reported here. METHODS: Data from the global MG SPOTLIGHT Registry were collected from patients with gMG currently or previously treated with eculizumab or ravulizumab in routine clinical practice. Effectiveness was evaluated among patients with ≥3 outcome measurements using MG Activities of Daily Living (MG-ADL) and MG-QOL 15-revised (MG-QOL15r) patient-reported outcomes and/or Myasthenia Gravis Foundation of America Clinical Classification (MGFA class) physician assessments. Safety data were also assessed. RESULTS: 189 patients were treated with eculizumab. Mean (95% CI) MG-ADL scores (n=110) decreased by 4.2 (-5.0, -3.4) points and MG-QOL15r scores (n=40) decreased by 7.5 (-9.9, -5.0) points from before eculizumab initiation to first assessment during/after treatment (median eculizumab treatment duration: 18.0 months). 45/103 (43.7%) patients were MGFA class 0-II before eculizumab versus 89/103 (86.4%) at first assessment. After transitioning to ravulizumab, improvements in MG-ADL scores (n=37), MG-QOL15r scores (n=14), and MGFA class (n=34) were maintained (median ravulizumab treatment duration: 8.7-11.4 months). Few treatment-related serious adverse events (eculizumab: Aspergillus infection, nervous system disorder [n=1 each]; ravulizumab: anaphylactic reaction [n=1]) and no meningococcal infections were reported with eculizumab or ravulizumab treatment. CONCLUSIONS: In routine clinical practice, eculizumab was well tolerated and effective for patients with gMG. Treatment benefits were maintained after transition to ravulizumab.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
