Study Summary

This trial is studying how well adalimumab works compared to placebo in treating patients with MPS I, II, or VI.

Who is the study for?
This trial is for children and adults over 5 years old with Hurler Syndrome, Hunter Syndrome, or Maroteaux-Lamy Syndrome who have either been treated with ERT for at least a year or not treated at all. Participants must have joint motion limitations in at least 3 joints, weigh more than 15 kg, and experience significant pain.Check my eligibility
What is being tested?
The study tests the safety and effectiveness of Adalimumab injections compared to saline solution (placebo) on joint and skeletal disease in patients with MPS I, II or VI. It's randomized and double-blind: participants don't know if they're getting the real drug or placebo.See study design
What are the potential side effects?
Adalimumab may cause allergic reactions, increased risk of infections including TB, potential heart issues like congestive heart failure, liver problems such as Hepatitis B reactivation, nervous system disorders like multiple sclerosis or Guillain-Barre syndrome.
