About this study
Official title: Population Pharmacokinetic and Pharmacodynamic Modeling of Microemulsion Propofol in Healthy Volunteers: Comparison With Lipid Emulsion Propofol
AquafolTM (Daewon Pharmaceutical Co., Ltd., Seoul, Korea) is a microemulsion propofol that has been developed for eliminating lipid solvent-related adverse events of long chain triglyceride emulsion (LCT) propofol (Diprivan®; AstraZeneca, London, United Kingdom), such as infection, fat embolism, hypertriglyceridemia and pancreatitis. Originally, AquafolTM was formulated with 8% polyethylene glycol 660 hydroxystearate (Solutol HS 15, BASF Company Ltd., Seoul, Korea) and 5% tetrahydrofurfuryl alcohol polyethylene glycol ether (Glycofurol, Roche, Basle, Switzerland). A phase 1 study to assess the safety and tolerability of polymeric vehicles of this formulation in healthy volunteers showed dose-limiting toxicity. Subsequently, it was reformulated with 10% purified poloxamer 188 (PP188) as a nonionic block copolymer surfactant and 0.7% polyethylene glycol 660 hydroxystearate as a nonionic surfactant. Alterations in propofol formulation may result in altered pharmacokinetic, pharmacodynamic characteristics.
The aim of this study was to compare the pharmacokinetics and pharmacodynamics of propofol microemulsion and lipid emulsion, using noncompartmental analysis and population analysis with mixed effects modeling.
Read the detailed description
The Subjects fasted for 6 h before study drug administration. An 18-gauge angiocatheter was placed in a vein of the antecubital area. A second angiocatheter was placed in the contralateral radial artery for frequent blood sampling. Subjects were monitored with electrocardiography, pulse oximetry, end-tidal carbon dioxide concentration, and invasive blood pressure measurement (Datex-Ohmeda S/5;Planar Systems, Inc., Beaverton, OR) and Bispectral Index (BIS) (Aspect 2000; Aspect Medical Systems, Inc., Newton,MA). In addition, the electroencephalographic activity of seven monopolar channels (Fp1, Fp2, F3, F4, Cz, P3, and P4, referenced by A2) was recorded by QEEG-8 (LXE3208, Laxtha Inc., Daejeon, Korea).
The subjects were stratified into three age groups (19-40, 41-64, and > 65 yr), and each group included 10 male and 10 female volunteers. Each subject received both propofol formulations in a crossover fashion separated by a 7-day washout period, and the order of the drug administration was randomized. Subjects received both propofol formulations during 60 min. The infusion rate was assigned according to a nonblinded, randomized design to 1.5, 3, 6, or 12 mg/kg/hr.
Samples were collected in ethylenediaminetetraacetic acid (EDTA) tube and centrifuged for 10 min at 3,500rpm. Plasma was stored at -70°C until assay. Arterial blood samples (4 ml) were taken at preset intervals: 0, 0.5, 1, 1.5, 2, 3, 4, 6, 8, 10, 15, 20, 30, 40, 50, 58, 60, 62, 66, 70, 80, 90, 120 and 150 min after administration of propofol. Venous blood samples (4ml) were taken at preset intervals: 180, 240, 300, 600, 720 and 1,200 min after administration of propofol. In addition, arterial samples were drawn when LOC (loss of consciousness) and ROC (recovery of consciousness) were observed.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing propofol in people with Healthy, run by Asan Medical Center at 1 site in South Korea.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Jan 2012. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The aim of this study was to compare the pharmacokinetics and pharmacodynamics of microemulsion and lipid emulsion propofol. (time frame: Between 5/2/2009 until 5/31/2010). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00908726, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Jan 2012.
