28 Clinical Trials for Various Conditions
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 this study is to assess rates of decline in motor and cognitive functional measures, and to assess potential biomarkers, in order to identify potential outcome measure appropriate for use in therapeutic clinical trials.
This protocol is a decentralized, single cohort, natural history and biomarker study enrolling up to 20 participants with MPS IIIA (Sanfilippo syndrome). At least 10 participants (\~50%) must be less than four years old at the time of the Parent/LAR consent. The study will have a screening process and 7 study visits, e.g. home visits, that will consist of serum collection and completion of a remote assessment of the Vineland Adaptive Behavior Scales 3rd Edition (Vineland-3) MPS IIIA remains a devastating disease with a high unmet medical need. There is currently a limited number of available data to adequately characterize the progression of the disease. Analysis of blood biospecimens and adaptive behavior in this study will help researchers better understand the clinical progression of MPS IIIA. A better understanding of disease progression may assist in developing novel therapies for rare genetic disorders.
This is a multicenter, non-interventional, long-term follow-up (LTFU) study in participants who have been treated with ABO-101 in a prior trial. Eligible participants will undergo clinical evaluations at prespecified intervals for 3 years from the last visit in the prior clinical trial (up to 5 years post-treatment).
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.
The main objective of this study is to evaluate the safety/tolerability and efficacy of UX111 (previously known as ABO-102) in participants with Mucopolysaccharidosis IIIA (MPS IIIA).
The goal of this clinical trial is to test cannabidiol in Sanfilippo syndrome. The main questions it aims to answer are: 1) determine the safety of cannabidiol in Sanfilippo syndrome, and 2) explore the efficacy of cannabidiol in treating the neurobehavioral symptoms and functional outcomes of Sanfilippo syndrome. Each participant's caregiver will be asked to complete surveys related to the participant's behavior, mood, sleep, stooling, pain, and caregiver stress intermittently throughout the study. All participants will be enrolled into one of two cohorts based on enrollment order: 1. Sentinel Safety Cohort (first 5 participants) - all participants treated with Epidiolex (cannabidiol) 2. Controlled Cohort (next 30 participants) - participants randomized 1:1 (equal chance) to start treatment with Epidiolex (cannabidiol) or placebo for 16 weeks, followed by an 8-week washout period (no treatment). Participants then switch to the opposite treatment group for 16 weeks followed by all participants treated for 52 weeks with Epidiolex (cannabidiol).
ScreenPlus is a consented, multi-disorder pilot newborn screening program implemented in conjunction with the New York State Newborn Screening Program that provides families the option to have their newborn(s) screened for a panel of additional conditions. The study has three primary objectives: 1) define the analytic and clinical validity of multi-tiered screening assays for a flexible panel of disorders, 2) determine disease incidence in an ethnically diverse population, and 3) assess the impact of early diagnosis on health outcomes. Over a five-year period, ScreenPlus aims to screen 100,000 infants born in nine high birthrate, ethnically diverse pilot hospitals in New York for a flexible panel of 14 rare genetic disorders. This study will also involve an evaluation of the Ethical, Legal and Social issues pertaining to NBS for complex disorders, which will be done via online surveys that will be directed towards ScreenPlus parents who opt to participate and qualitative interviews with families of infants who are identified through ScreenPlus.
Open-label, clinical trial of scAAV9.U1a.hSGSH injected intravenously through a peripheral limb vein
The main objective of this study is to evaluate the efficacy and safety of UX111 for the treatment of MPS IIIA.
Eligible research subjects will receive an unrelated umbilical cord blood transfusion as a possible cure for their inherited metabolic disease. A portion of cord blood cells (ALD-101) will be separated from the cord blood unit and given approximately 4 hours after the standard cord blood transfusion. The study will test if the supplemental cells will increase the speed at which normal levels of circulating blood cells are re-established after transplant.
Hematopoietic stem cell transplantation has proven effective therapy for individuals with adrenoleukodystrophy (ALD), metachromatic leukodystrophy (MLD) or globoid cell leukodystrophy (GLD, or Krabbe disease). This protocol also considers other inherited metabolic diseases such as, but not limited to, GM1 gangliosidosis, Tay Sachs disease, Sanfilippo syndrome or Sandhoff disease, I-cell disease (mucolipidosis II). For patients with advanced or rapidly progressive disease, the morbidity and mortality with transplantation is unacceptably high. Unfortunately, there are no viable alternative therapeutic options for these patients; if transplantation is not performed the patients are sent home to die. Our group at Minnesota has developed a new protocol incorporating transplantation using a reduced intensity conditioning regimen designed to decrease toxicity associated with the transplant procedure. This regimen will make use of the drug clofarabine, which has lympholytic and immune suppressive properties without the neurologic toxicity observed in the related compound, fludarabine, commonly used for transplantation. In addition, several agents providing anti-oxidant and anti-inflammatory properties will be used to assist in the stabilization of the disease processes. This revised transplant protocol will test the following: 1) the ability to achieve engraftment with the reduced intensity protocol, 2) the mortality associated with transplant by day 100, 3) patient outcomes, based on differential neurologic, neuropsychologic, imaging and biologic evaluations prior to transplantation and at designated points after transplantation (day 100, 6 months, 1, 2 and 5 years). Additional biologic studies will include pharmacokinetics of clofarabine and mycophenolate mofetil (MMF). In addition, for patients undergoing lumbar puncture studies, cerebrospinal fluid (CSF) will be requested for determinations of biologic parameters.
The primary objectives of this study are to evaluate the long-term safety and tolerability of AX 250 administered to subjects with MPS IIIB by an implanted ICV reservoir and catheter and to evaluate the impact of long-term AX 250 treatment on cognitive function in patients with MPS IIIB as assessed by developmental quotient (DQ).
The study's primary objectives are to evaluate the safety and tolerability of AX 250 administered to subjects with MPS IIIB via an ICV reservoir and catheter and to evaluate the impact of AX 250 on cognitive function in patients with MPS IIIB as assessed by the Development Quotient.
Mucopolysaccharidosis type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B) is a severe neurodegenerative disorder. The purpose of this study is to learn more about the health problems in patients with MPS IIIB and how to measure these problems over time. It will particularly look at how the disease develops in young children. This is an observational study, so no experimental drug will be given. The results from this study will help us design future studies to measure whether these health problems get better when we give experimental drug for MPS IIIB.
The objective is to perform a retrospective chart review to generate data to evaluate the clinical characteristics and course of disease progression of MPS IIIB.
This is a multicenter, open-label, Phase 1/2 study to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and clinical efficacy of DNL126 in participants with Sanfilippo syndrome Type A (MPS IIIA). The core study period is 25 weeks (approximately 6 months) and is followed by a 72-week (approximately 18 month) open-label extension (OLE). Participants with MPS IIIA will be enrolled in two planned cohorts, and additional participants with MPS IIIA may be enrolled in three optional cohorts.
MPS IIIA is predominantly a central nervous system disease causing cognitive disability, progressive loss of acquired skills, behavioral and sleep disturbance. LYS-SAF302 is a gene therapy which is intended to deliver a functional copy of the SGSH gene to the brain. This is a phase 2-3 study to assess the efficacy in improving or stabilizing the neurodevelopmental state of MPS IIIA patients.

This is a natural history study for children up to 18 years of age who have been diagnosed with Mucopolysaccharidosis Type IIIB (MPS IIIB, also known as Sanfilippo Syndrome Type B). Mucopolysaccharidosis type IIIB is a severe neurodegenerative disorder. The information gathered from this trial may help inform the design and interpretation of subsequent interventional studies. No clinical intervention or study drug is provided by Allievex in this study.
The objectives of this study are to describe the clinical and biochemical characteristics and course of disease progression in participants with Mucopolysaccharidosis type IIIB (MPS IIIB)
The purpose of this study is to evaluate the natural course of disease progression in Mucopolysaccharidosis Type III (MPS IIIB) patients who are untreated to identify potential surrogate endpoints that may be utilized in future treatment trials of MPS IIIB using predefined assessments including standardized clinical, biochemical, neurocognitive, developmental, and imaging measures.
Hypothesis: Children diagnosed with a lysosomal disease will exhibit developmental, adaptive, and behavioral strengths and difficulties depending upon 1) biomedical risk factors (i.e. the specific genetic disorder responsible for the illness); 2) available modifying interventions, whether medical or behavioral; and 3) social risks in the children's families, neighborhoods and communities. A valid and reliable telephone-based surveillance system can successfully collect the data required to elucidate these developmental, adaptive and behavioral strengths and difficulties.
The purpose of this study is to evaluate the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of recombinant human heparan N-sulfatase (rhHNS, GC1130A) administered via intracerebroventricular access device in pediatric patients with Sanfilippo Syndrome Type A (MPS IIIA).
This study is planned to document, through retrospective and prospective data collection, syndrome progression in children and young adults with MPS IIIC.
A Global Phase III multicenter, randomized, assessor-blinded, active-controlled designed to evaluate safety and efficacy of study drug for the treatment of the MPS II.
This extension study will allow participants to continue receiving treatment with HGT-1410 and to initiate treatment in patients who received no-treatment in Study HGT-SAN-093, and will evaluate the long-term safety and efficacy of the study drug.
Mucopolysaccharidosis (MPS) syndromes are disorders characterized by enzyme deficiencies, and they have been linked to heart health complications. However, there are currently no proven markers of heart and artery health for this population. The main purpose of this observational study is to evaluate the ease and convenience of a non-invasive measurement of artery function in MPS I, MPS II and MPS VI patients compared to healthy control subjects. An observational study is a research design meaning that there is no treatment in this study. The research questions are: 1. Is the artery health of MPS I, II and VI patients different than healthy controls? 2. Is the artery health of MPS VI patients different than MPS I and II patients? It is hypothesized that MPS patients will have poorer outcomes of artery health compared to healthy controls.
