9 Clinical Trials for Various Conditions
J3Z-MC-OJAB is an open-label, Phase 1/2, multicenter study to evaluate the safety and efficacy of single-dose LY3884961 (formerly PR001) in infants diagnosed with Type 2 Gaucher disease (GD2). For each patient, the study will be approximately 5 years in duration. During the first 12 months after dosing, patients will be evaluated for the effects of LY3884961 on safety, tolerability, immunogenicity, biomarkers, and efficacy. Patients will be followed up for an additional 4 years to monitor safety and changes on selected biomarkers and clinical outcomes.
This study will use an experimental method of delivering the enzyme glucocerebrosidase directly into the brain of a patient with Gaucher disease to treat disease symptoms. Patients with Gaucher disease have insufficient levels of glucocerebrosidase. As a result, substances normally broken down by this enzyme accumulate in the body, causing damage to the brain and other organs. Symptoms of Gaucher disease outside the brain can be treated by infusing the missing enzyme intravenously (IV, through a vein). However, IV infusions do not help the neurologic symptoms of the disease, because the enzyme cannot get into the brain. This study will use a new technique called convection-enhanced delivery to try to introduce glucocerebrosidase directly into the brain. This single-patient study includes an 8-month-old male with Type 2 Gaucher disease with progressive neurological decline. In preparation for the enzyme infusion, the patient will have a complete physical examination, including a detailed neurological examination, and blood and urine tests. On the day of surgery, the child will be placed under general anesthesia for magnetic resonance imaging (MRI) of the brain. MRI uses a magnetic field and radio waves to produce images of body tissues and organs. For this procedure, the child lies on a table that is moved into the scanner (a narrow cylinder), wearing earplugs to protect his hearing from the loud knocking and thumping sounds that occur during the scanning process. He will then be brought to the operating room for the infusion procedure, as follows: An incision will be made in the scalp and a small hole drilled through the skull. Then, a small tube (cannula) will be positioned through the hole into the target area in the brain. Once the tip of the cannula is in place, it will be connected with tubing to a syringe filled with glucocerebrosidase in saline (salt water). The child will then have a second MRI scan to make sure the cannula is placed correctly and to monitor delivery of the glucocerebrosidase to the brain. The child will be monitored closely with MRI scans every 30 to 60 minutes during the infusion to look for fluid in the brain and determine the extent of the enzyme perfusion. The infusion will last no longer than 6 hours and will be stopped when the full dose of enzyme has been delivered. The cannula will be removed and the scalp incision closed. The child will stay in the hospital for observation from 4 to 10 days, with at least 24 hours in the intensive care unit and 3 to 7 days in the pediatric unit. The child will be seen in the clinic two weeks after discharge and then once a month for 3 months to evaluate any possible effects of the surgery. These follow-up visits include a repeat MRI scan and neurological examination. After the first 3 months, visits may be less frequent. If the child continues to have symptoms during the course of follow-up or his neurologic status worsens, additional enzyme infusions will be offered, possibly including treatment of the brainstem. If the child gains no benefit after three infusions have been performed, no additional infusions will be offered. If there appears to be any neurological benefit, additional infusions may be offered.
This study is being conducted to better understand the natural course of GM1 gangliosidosis, GM2 gangliosidoses and Gaucher disease Type 2 (GD2). Information is planned to be gathered on at least 180 patients with GM1 gangliosidosis, GM2 gangliosidoses, and Gaucher Disease type 2. Retrospective data collection is planned for at least 150 deceased patients (Group A). Group B is for patients alive at the time of enrollment. In Group B it is planned to prospectively collect more comprehensive data from at least 30 patients. The purpose of this study is to collect relevant information for a adequate design of a potential subsequent research program in these diseases. In this study no therapy is being offered.

The purpose of this study is to learn more about Gaucher disease. The information we collect from medical histories and a blood sample from people with Gaucher disease may help us pinpoint certain things that are different between people who have Gaucher disease and people who do not have Gaucher disease. This information may be useful in the future to help find new treatments for Gaucher disease.
This project is expected to elucidate role of different therapeutic interventions: SRT in comparison to ERT in influencing immune aspects of GD pathology, as well as bone involvement.
This is a multicenter, randomized trial to compare the safety and efficacy of two dosing frequencies of Cerezyme® in patients with Gaucher disease who are currently being treated with Cerezyme®. Approximately 90 patients will be randomized in a 2:1 (q4 : q2) ratio to one of two treatment arms at up to 26 study centers worldwide. Patients will continue to receive the same total 4-week dose that they were receiving prior to study enrollment, however, they will be randomized to receive either their total 4-week dose in two infusions, one infusion every 2 weeks or their total 4-week dose in one infusion every 4 weeks. The randomization scheme will ensure a 2:1 balance between the every 4-week versus every 2-week infusion groups, respectively.
This is a multicenter, long-term, follow-up trial of participants with Gaucher disease type 1 who received FLT201 treatment in a preceding clinical trial. Participants will be followed for 5 years post-treatment.
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.
