Clinical Trial Characterizing the Bioavailability of 1-Octanol in Adults With Ethanol-responsive Essential Tremor
NCT00102596 · View on ClinicalTrials.gov ↗
Study Summary
OVERVIEW Essential tremor (ET) is a common movement disorder affecting 0.4% of the general population and up to 14% of people 65 years and older. Response to medications such as beta blockers and primidone may be of benefit, but are often accompanied by intolerable side effects. Response to ethanol, on the other hand, has a roughly 80% chance of significant tremor reduction, though daily use of this as a treatment has potentially serious medical, social, and legal consequences. The leading hypothesis for ET pathophysiology is an unmasking of spontaneous oscillations originating in neurons of the inferior olive. Both ethanol and 1-octanol have been shown to reduce these spontaneous oscillations in an animal model of ET; however, 1-octanol does this at a dose much lower than that leading to intoxication, suggesting in may be useful in the treatment of essential tremor. Our initial studies with 1-octanol have shown it to be safe at dosages up to 64mg/kg without signs of intoxication, while at the same time showing benefit. OBJECTIVE We plan to evaluate the efficacy of different 1-octanol formulations in humans based on accelerometry and spirography. We will also evaluate drug and metabolite bioavailabilities using a high performance liquid chromatography (HPLC) detection method from plasma and urine samples. STUDY POPULATION We will study adult subjects with ethanol-responsive Essential Tremor (ET). DESIGN This study is designed as a two-phase unblinded inpatient study of adults with ET receiving weight-adjusted oral dosages of 2 different formulations of 1-octanol in a crossover fashion. Phase I of the study is designed to develop an octanol detection assay using HPLC. Four subjects will receive daily escalating dosages (1-32 mg/kg) of a single 1-octanol formulation followed by a crossover trial of both formulations at a dosage of 64 mg/kg. Phase II will study 20 subjects receiving one of the two formulations at 64 mg/kg on inpatient day 1 followed by a 24 hou

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00102596
The ClinicalTrials.gov registry entry for NCT00102596 describes a study currently listed as completed. It is categorized as Phase 2, 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 21 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Neurological Disorders and Stroke (NINDS), which has 339 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 Essential Tremor appearing as the primary indexed condition, and to 1 intervention — of which 1-Octanol is the first listed. 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: NCT00102596 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.
