Phase I/II, open label, multicenter, multinational (Japan, Brazil and the US) extension study of JR-171-101 (NCT04227600) for the treatment of MPS I
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.

Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, is caused by a deficiency of iduronate-2-sulfatase (IDS) leading to an accumulation of glycosaminoglycans (GAGs) in tissues of MPS II patients, resulting in characteristic storage lesions and diverse disease sequelae, and in patients with the more severe form of the disease, irreversible neurocognitive decline and higher morbidity and mortality than in patients with the attenuated form of the disease. There is currently limited information on the natural history of MPS II, especially with respect to neurocognitive decline in patients with the more severe form of the disease. This study is planned to be an observational medical records review study (data collected retrospectively and no investigational product treatment or procedures) in subjects with the severe form of MPS II. Collectively, the data may inform the design of future MPS II gene therapy treatment studies and may be utilized as historical comparative control data.

OBJECTIVES: I. Evaluate the safety and feasibility of treating mucopolysaccharidosis II (mild Hunter syndrome) by lymphocyte gene therapy. II. Determine the levels of iduronate-2-sulfatase enzyme in these patients attained by infusing increasing doses of lymphocytes transduced with a retroviral vector designed for insertion and expression of this iduronate-2-sulfatase gene (L2SN). III. Determine the duration of survival of these transduced cells in these patients. IV. Determine whether monthly infusion of L2SN-transduced lymphocytes accomplishes metabolic correction (as measured by glycosaminoglycan excretion), decrease in liver or spleen volume, any therapeutic effect upon cardiac and pulmonary dysfunction, or any other effects from treatment.
The main aim of this study is to evaluate the ability of a prophylactic immune tolerizing regimen (ITR) to prevent or reduce the development of high titer anti-idursulfase antibodies in treatment-naïve participants with Hunter syndrome. In this open label, single arm study, all participants will receive ELAPRASE treatment and a prophylactic ITR. Participants will be treated with ELAPRASE for up to 104 weeks. The prophylactic ITR will start 1 day prior to the start of ELAPRASE. The prophylactic ITR will consist of a 5-week cycle of: Rituximab (intravenously \[IV\], weekly for 4 weeks); Methotrexate (oral, 3 times per week for 5 weeks) and intravenous immunoglobulin (IVIG) (IV, every 4 weeks of the cycle). Following the completion of 1 cycle, an assessment will be made at Month 6, 12, and 18 regarding the need for administering another 5-week cycle of the ITR. Participants will be in the study for approximately 112 weeks (including 6 weeks for screening, up to 104 weeks for treatment, and 2 weeks for follow-up).
