About this study
Official title: The Study of Pharmacokinetics and Pharmacodynamics of a Loading Dose Cisatracurium in Critically Ill Patients
Pathophysiological changes influenced by multiple factors in critically ill patients, has a significant impact on pharmacokinetics (PK) and pharmacodynamics (PD) of cisatracurium. In order to understand better and find an appropriate dosing regimen, the purpose of this study is to investigate the PK and PD of a loading dose cisatracurium in critically ill patients.
Cisatracurium, nondepolarizing neuromuscular blocking agents (NMBAs), are commonly used in intensive care units because of a lesser effect on hemodynamic parameters and a reduction in mortality rate in ARDS patients. Loading dose recommended in clinical practice guidelines for sustained neuromuscular blockade in the adult critically ill patient is 0.1-0.2 mg/kg. Then, maintenance dose of 1-3 mcg/kg/min is followed regarding indications, such as ARDS. However, this recommended loading dose might not be adequate in critically ill patients, the study in this specific population might be needed.
Read the detailed description
Neuromuscular blocking agents (NMBAs) are commonly used in critically ill patients, especially in adult respiratory distress syndrome (ARDS). Use of NMBAs to facilitate mechanical ventilation, to control patient/ventilator asynchrony and to reduce uncontrolled muscle tone in special conditions including tetanus, therapeutic hypothermia, and status epilepticus were increasingly found in current clinical practice.
Cisatracurium, 1Rcis-1'Rcis isomer of atracurium, is benzylisoquinolium nondepolarizing NMBAs which is three to five folds higher potency than atracurium besylate. The degradation of cisatracurium by hofmann elimination and ester hydrolysis in plasma generates laudanosine and a monoquaternary acrylate metabolite. Clinical practice guidelines for sustained neuromuscular blockade in the adult critically ill patient published in year 2016 strongly recommended cisatracurium due to a reduction in incidence of prolonged blockade, cardiovascular related adverse events and anaphylactic reactions. Moreover, recent evidence showed that early use of cisatracurium in early severe ARDS patients led to a significant reduction in mortality.
Regarding pharmacokinetics and pharmacodynamics of cisatracurium in critically ill patients, there were multiple factors affected cisatracurium blood concentration and neuromuscular blockade actions. Several reports demonstrated that pathophysiological changes, such as age, hypothermia/ hyperthermia, electrolyte imbalance and acid-base disturbances, had a significant impact on PK and PD of cisatracurium. Currently, there were an increasing data of slow response and less paralysis effect in critically ill patients receiving standard dose of cisatracurium. These may be explained by inadequate drug concentration at target organ, therefore, treatment failures regarding recommended dose of cisatracurium has been reported. Consequently, higher cisatracurium dose with higher drug concentration level might overcome a problem of inadequate level and therapeutic failure while receiving a standard dose of cisatracurium (a loading dose of 0.1-0.2 mg/kg, followed by a maintenance dose of 1-3 mcg/kg/min)

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing cisatracurium in people with Critical Illness and Respiratory Distress Syndrome, Adult, run by Mahidol University at 1 site in Thailand.
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 4 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 6 Mar 2019. 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 Thailand. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Total plasma concentration-time data (time frame: Pre-dose through 60 minutes post-dose). The study lists 3 primary outcomes in all. 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 NCT03337373, which also lists 11 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 6 Mar 2019; AzTrials last refreshed its copy on 8 Nov 2026.
