Natural History of Morquio A Syndrome.

New testing approaches could better measure progress in rare metabolic disease patients, helping regulators and doctors evaluate experimental treatments fairly.

This natural history review of Morquio A syndrome (MPS IVA) highlights critical gaps in endpoint validation for clinical trials, as standard endurance tests fail patients with severe phenotypes or postoperative limitations. The authors advocate for non-invasive quantitative multisystem tools and surrogate biochemical biomarkers to enable regulatory-grade endpoints across the full Morquio A phenotypic spectrum.
