Evaluation of Biochemical Markers and Clinical Investigation of Niemann-Pick Disease, Type C
NCT00344331 · View on ClinicalTrials.gov ↗
Study Summary
This study will evaluate clinical and laboratory tests that might be useful in determining if an investigational drug can slow the progression of Niemann-Pick Disease, Type C (NPC), a genetic disorder that results in progressive loss of nervous system function. The study will: 1) look for a clinical or biochemical marker that can be used as a measure of response to treatment, and 2) define the rate of progression of biochemical marker abnormalities in a group of NPC patients who will later be invited to enroll in a treatment trial. Patients of any age with NPC may be eligible for this study. Participants undergo the following procedures every 6 months during 4- to 5-day admissions at the NIH Clinical Center. * Medical evaluation, including medical history, physical exam, neurological exam, neuropsychometric evaluation, and blood and urine tests. * Lumbar puncture (spinal tap): A sample of cerebrospinal fluid (CSF), the fluid that bathes the brain and spinal cord, is obtained for study. After administration of a local anesthetic, a small needle is inserted in the space between the bones in the lower back where the CSF circulates below the spinal cord. A small amount of fluid is collected through the needle. * Eye exam and eye movement study: The pupils of the eye are dilated to examine the structures of the eyes. For the eye movement study a special contact lens is placed on the eye and the patient looks at a series of target light spots moving on a screen. * Hearing tests. * Electroretinography (in patients who can cooperate with the test) to measure the function of the retina. Before the test, the patient's pupils are dilated and an electrode (small silver disk) is taped to the forehead. The patient sits in a dark room for 30 minutes and then a special contact lens is placed on one eye after it has been numbed with drops. The contact lens senses small electrical signals generated by the retina when lights flash. During the ERG recording, the eye is stimulated wit

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00344331
The ClinicalTrials.gov registry entry for NCT00344331 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 900 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), which has 237 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Niemann-Pick Disease, Type C appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00344331 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll. Verify current status, eligibility criteria, and contact details directly at ClinicalTrials.gov, and discuss any participation decision with your own healthcare provider.
