Real-world treatment with elosulfase alfa in patients with MPS IVA is associated with improved endurance over time
Bibliographic record
Abstract
Purpose To assess the real-world effectiveness of enzyme replacement therapy (ERT; elosulfase alfa) on endurance in the treatment of mucopolysaccharidosis type IVA (MPS IVA) using cross-sectional data. Methods The 6-minute walk test (6MWT) distances of ERT-treated and untreated participants from the Morquio A Registry Study and Morquio A Clinical Assessment Program were described for age groups of interest (5 to <7 years, 9 to <11 years, 14 to <16 years, and 20 to <30 years). Linear and quantile univariate regression were performed to explore variables associated with 6MWT (ERT, sex, age, standing height, body weight, region, and race). Multivariate regression analyses were performed using covariates identified in univariate analyses ( P < .10), adjusting for confounders. Results A total of 471 participants were included; baseline characteristics were similar within age groups. Median 6MWT distances were numerically greater in ERT-treated versus untreated participants within each age group. Quantile regression adjusting for multiple factors indicated a consistent trend of improved 6MWT with ERT treatment. Standing height was also associated with longer 6MWT in the multivariate quantile analysis, except in participants aged 5 to <7 years. Conclusion This analysis assessed associations between ERT exposure and endurance to confirm the real-world, long-term effectiveness of elosulfase alfa in participants with MPS IVA.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
