Clinical Trial Summary

Randomized, double-blind, placebo-controlled, parallel-group, single-center study followed by open-label phase, to evaluate the effects of adalimumab compared to placebo on the change from baseline in joint and skeletal disease in children and adults with mucopolysaccharidosis (MPS) I, II or VI.

Description:

This study is a randomized, double-blind, placebo-controlled, parallel-group, single-center study followed by open-label phase, to evaluate the effects of adalimumab compared to placebo on the change from baseline in joint and skeletal disease in children and adults with mucopolysaccharidosis (MPS) I, II or VI. Children and adults diagnosed with MPS I, II or VI, with significant joint restrictions and pain will be randomized to adalimumab treatment or placebo treatment for the first 16 weeks. This will be followed by a 32-week open label adalimumab treatment phase.
