Summary
The purpose of the study is to collect preliminary data on whether the drug adalimumab (also called Humira) can decrease pain and stiffness, improve quality of life, and is safe in people with mucopolysaccharidosis type I, II, or VI. In this study people will be randomly assigned to one of two groups. One group will be treated with adalimumab the first 16 weeks of the study and then with a saline injection for the last 16 weeks of the study. The other group will start with the saline injection for 16 weeks and then switch to adalimumab for the last 16 weeks. The study subject and the study doctor and study coordinator will not know what group a subject is in until the study is done. Adalimumab is given as an injection, just under the skin, every 2 weeks. Both groups will have blood drawn at a screening visit, and then 7 more times over the 32 week study. There will be safety labs done (liver and immune function tests). Other safety tests include a chest X-ray and screening for tuberculosis exposure - these will be done at the screening visit and later in the study if there is concern for tuberculosis exposure or a persistent cough. The following will also be done at screening, the first, middle, and last study visits: 1) a pregnancy test in all girls 8 and older, 2) questionnaires that ask about pain, how MPS impacts social and physical function, and other quality of life questions, 3) height and weight. Finally, a physical exam, that includes for children and adolescents a check of where they are in puberty, will be done by a study physician at the first, middle, and last visits. There are risks to taking adalimumab that include redness and pain where the injection is given, a decreased ability to fight off infections, and others. The safety tests are designed to identify and decrease the risk associated with adalimumab. The study physicians believe that the potential benefit of adalimumab on pain, quality of life, and other MPS related problems outweigh the potential risks of treatment.
