Active clinical trials for "Mucopolysaccharidoses"

This is a multi-center, open label, study conducted to evaluate the safety of laronidase administered by intravenous drip infusion in Japanese patients with MPS I disease. Following baseline evaluation, patients will receive weekly infusions of JC0498 at an intravenous dose of 100 units/kg. Patient safety will be monitored continuously throughout the trial. In addition, the effects of JC0498 treatment in this patient population will be assessed by periodically evaluating aspects of MPS I disease in patients at scheduled intervals over the duration of the trial. Since patients may be eligible for the trial if they have received JC0498, a portion of the data may be captured retrospectively and recorded onto the case report forms (CRFs). This study represents the first good clinical practice (GCP) effort to characterize MPS I in the Japanese population and evaluate the effects of JC0498 on disease manifestations.

AGT-181 is a fusion protein containing alpha-L-Iduronidase that is intended to deliver the enzyme peripherally and to the brain, when administered intravenously. This study is an extension of a safety and dose ranging study to obtain long term safety and exposure data, as well as information on the biological activity of the investigational drug

Study to evaluate the safety and tolerability of intravenous (IV) administration of SBC-103 in participants with mucopolysaccharidosis III, type B (MPS IIIB, Sanfilippo B) with evaluable signs or symptoms of developmental delay.

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.

There is currently no treatment for MPS IVA other than supportive care for the clinical manifestations of the disease. Enzyme replacement therapy (ERT) with BMN 110 to replace the deficient GALNS is a potential new treatment option for MPS IVA patients. BMN 110, containing recombinant human GALNS (rhGALNS) developed by BioMarin is expected to reduce the progressive, pathologic accumulation of KS, and improve signs and symptoms of the disease. The objective of this Phase 3B open label study (110-502) will be to evaluate the safety and tolerability of 2.0 mg/kg/week (qw) of BMN 110 in Australian patients with MPS IVA. In addition, a number of secondary and tertiary efficacy endpoints will also be investigated. The dose and regimen of BMN 110 have been selected on the basis of data from a Phase 1/2 clinical study with BMN 110, nonclinical and in vitro studies with BMN 110, and clinical and nonclinical data from other enzyme replacement therapies. Extension Phase is included per amendment dated 10Mar 2014: To provide patients enrolled in the Initial Phase access to BMN 110 until commercial product becomes available in Australia and continue to assess long-term safety

P2-SAF-301 is an open-label interventional study without administration of investigational product, evaluating the long-term safety and tolerability of intracerebral SAF-301 previously administered to 4 patients with Sanfilippo type A syndrome. The primary objective is to collect additional safety and tolerability data on intracerebral SAF-301 previously administered to 4 patients with Sanfilippo type A syndrome. The secondary objective is to further collect data to assess the effects of SAF-301 on neurological and psychological status, and potential biological markers.

It is a phase I open-label single-dose, dose-escalation cohort study to evaluate of the tolerance, safety, and pharmacokinetics of GNR-055 in healthy volunteers

Sanfilippo syndrome, or mucopolysaccharidosis type III (MPS III), is a disorder of metabolism, associated with insufficient production of a lysosomal enzyme needed for normal cell function. As a consequence of the cellular dysfunction, patients with this disorder develop progressive, irreversible neurodegeneration. Sadly, to date no evidence-based treatments are available. Inflammation has been connected with disease pathogenesis in the MPS disorders. Therapies aimed at decreasing inflammation are currently being studied in many MPS disorders and benefits in both brain and other parts of the body have been reported.Decreasing interleukin-1 (IL-1) in an animal model of MPS III showed benefits in brain disease and behavior. Thus, we think that anakinra (Kineret), which decreases IL-1 levels in the body, will improve behavioral and other problems in children with MPS III. Anakinra is approved by the FDA for treatment of rheumatoid arthritis (RA) and neonatal-onset multisystem inflammatory disease (NOMID). It is not approved for any MPS disorder. The design of this study is an open-label, single center, pilot study of 20 participants with MPS III. There will be an initial screening visit, followed by an 8-week observational period, then a 36-week treatment period, and finally another 8-week observational period to determine any effects of withdrawal from the treatment. During visits the participants will undergo a medical history, a physical examination, and anthropometric measurements. Blood, urine, and stool will be collected for biomarker levels and safety laboratory studies. Questionnaires will be completed with questions related to behavior, stooling, sleep, and activities of daily living. Seizure and movement disorders will be monitored as well. The most common risks of receiving anakinra, based on RA and NOMID experience, include local injection site reactions, headache, nausea, vomiting, arthralgia, and flu-like symptoms. The most serious potential risk is a serious infection and neutropenia. However, because so few people with MPS have been treated with anakinra, all the risks related to MPS patients receiving anakinra are not currently known. Additional risks related to taking part in the study include some pain, bruising, and/or bleeding due to blood draws/peripheral IV placement, and discomfort with completing some of the questionnaires. The expected potential direct benefits include, but are not limited to, improved behavior, sleep, stooling, communication, mood, and gait; as well as decreased seizure frequency, disordered movement and fatigue. However, there is no guarantee that participants will get any benefit from being in this study.
