Study design details

Main study objective

1. To characterize and describe the MPS IVA population as a whole, including the heterogeneity, progression, and natural history of MPS IVA.
2. To evaluate the long-term effectiveness and safety of Vimizim, including but not limited to the occurrence of serious hypersensitivity reactions, anaphylaxis, and changes in antibody status.

Data analysis plan

Efficacy analysis will include all patients in the Efficacy Population, and will be conducted annually and over the duration of MARS. All efficacy variables will be summarized descriptively for baseline and post-baseline. When applicable for the specific efficacy variable, the change from the baseline to post-baseline (post–baseline at annual or semi-annual timepoints, depending on the specific efficacy variable), and/or its percent change will be summarized descriptively. The analyses of safety will include all patients in the Safety Population. Safety data, including vital signs, findings from physical examinations, concomitant medications, and other safety assessments, will be summarized descriptively. Incidence rate calculations will be completed. Where applicable, descriptive statistics will include the number of patients and mean, median, standard deviation, minimum, and maximum values for continuous variables and count and percent for categorical variables.
