13 Clinical Trials for Various Conditions
The primary objective of the study was to evaluate the efficacy and safety of UX007 in the treatment of disabling paroxysmal movement disorders associated with Glut1 DS.
This study is being done to assess the safety and long-term efficacy of triheptanoin in pediatric patients with Glut1 DS over a 5-year treatment period. Glut 1 is a protein that helps transport glucose to the brain. Glucose is the brain's primary source of energy. Glut 1 DS prevents this protein from being effectively produced, causing deprivation of energy to the neurons of the of the brain. Glut1 DS is a severely debilitating disease characterized by seizures, developmental delay and movement disorder. There are currently no approved treatments specific to Glut1 DS. Treatment generally includes medications for control of seizures. The use of a ketogenic diet can be effective in controlling seizures when medications are ineffective or provide insufficient control. However, the ketogenic diet may be very difficult for patients to maintain for long periods of time, and there may be negative secondary long-term effects of ketogenic diet.. Triheptanoin is metabolized to molecules that can provide an alternative energy source to the brain, and appears to help in controlling seizures without many of the difficulties of the ketogenic diet. Eligible patients may be those who have been diagnosed with GLUT1 DS, and have discontinued or are not currently on ketogenic diet, or are able to tolerate triheptanoin if they have been treated or are currently being treated with triheptanoin and do not qualify for any other clinical trial.
The purpose of this trial is to determine if an alternative energy source will impact brain metabolism in a disorder characterized by glucose metabolism failure in the brain. The central hypothesis tested in this investigation is whether circumventing impaired glucose metabolism is feasible, safe and potentially promising by supplying anaplerotic precursors through metabolism of odd-carbon fatty acids that can enter the citric acid cycle (CAC) through alternative metabolic pathways.
The primary objectives of the study are to evaluate the efficacy of UX007 compared to placebo as measured by the reduction from randomization to Week 8 in frequency of seizures and to evaluate the safety of UX007 via adverse event (AE) rates, laboratory values, and electrocardiogram (ECG).
This proposal is an investigator-initiated, single-site proof of concept trial. Five patients will undergo isovolemic hemodilution-red cell exchange (IHD- RBCx) with up to 10 units of red cell antigens (Rh group, Kell, Duffy, Kidd blood group antigens) matched normal donor red cells to replace a target of 70% of the patient's red cells with donor red cells. The procedure will be performed as an outpatient according to protocols established for sickle cell anemia patients. One of the investigators is an expert on RBCx and will oversee the transfusion. Subjects will be assessed before and after transfusion, and at two months post transfusion. Outcome measures include neurological exam, electroencephalography (EEG), neuropsychological testing, and biochemical assays.
The primary objective of the study is to evaluate the long-term safety of UX007 in Glut1 DS participants.
This is a single-site, open-label, phase II trial of C7, a food supplement or medical food, for the development of treatment outcome measures for glucose transporter type I deficiency (G1D). The primary outcome measures are: 1. Safety and tolerability of C7 as measured by changes in comprehensive blood work, including lipid and free fatty acid panels, self-reported side effects and clinical exam; 2. Changes in brain metabolic rate by MRI and EEG measurements during C7 treatment; and 3. Maintenance of ketosis in G1D patients on ketogenic diet, as measured by serial ketone levels during treatment initiation.
The goal is to develop methodology to monitor flux in the citric acid cycle in brain via 13C nuclear magnetic resonance (NMR) spectroscopy at 7 Tesla.
Forty-five subjects receiving no dietary therapy with a proven G1D diagnosis will be enrolled. To evaluate the effect of C7 supplementation of a regular diet on a EEG activity in addition to IQ, language, working memory, processing speed, emotional and behavioral functioning, ataxia, and other neuropsychological and neurological performance indices in children and adults genetically diagnosed with G1D receiving a regular diet at enrollment.
To determine the maximum tolerated dose (MTD), as a percentage of calories consumed, of triheptanoin (C7 oil; C7) in a pediatric and adult patient population genetically diagnosed with glucose transporter type 1 deficiency disorder (G1D).
This protocol provides ongoing access to triheptanoin for patients who did complete an initial pilot protocol, and provides the opportunity to collect long-term safety data from patients treated with triheptanoin.
The purpose of this protocol is to create a registry for patients diagnosed with Glucose Transporter Type 1 Deficiency (G1D), or patients experiencing symptoms consistent with G1D but not yet diagnosed, to enter medical information for physicians and other health researchers to analyze to increase the understanding of G1D and any sub-diagnoses.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
