A Phase 2 study testing Dexmedetomidine and Lorazepam in people with Delirium, run by Vanderbilt University at 1 site in United States.
Trial summary
Delirium has recently been shown as a predictor of death, increased cost, and longer length of stay in ventilated patients. Sedative and analgesic medications relieve anxiety and pain, but may contribute to patients' transitioning into delirium. Read more about this study

About this study
Official title: A Randomized, Double-blind Trial in Ventilated ICU Patients Comparing Treatment With an Alpha2 Agonist Versus a Gamma Aminobutyric Acid (GABA)-Agonist to Determine Delirium Rates, Efficacy of Sedation, Analgesia and Discharge Cognitive Status
Delirium has recently been shown as a predictor of death, increased cost, and longer length of stay in ventilated patients. Sedative and analgesic medications relieve anxiety and pain, but may contribute to patients' transitioning into delirium. It is possible that modifying the paradigm for sedation using novel therapies targeted at different receptors, such as dexmedetomidine targeting alpha2 receptors and sparing the GABA receptors, could provide efficacious sedation yet reduce the development, duration, and severity of acute brain dysfunction (delirium).
Read the detailed description
Delirium occurs in 60-80% of ventilated Intensive Care Unit (ICU) patients and is independently associated with prolonged hospital stay, higher cost, a 3-fold increased risk of dying by six months and ongoing neuropsychological dysfunction. Hypothesis: Based on our preliminary work, we hypothesize that standard use of GABA agonist sedatives such as lorazepam and propofol may contribute to ICU delirium and its attendant untoward clinical outcomes. An alternative sedation strategy targeting alpha2 receptors and sparing GABA receptors (dexmedetomidine) might reduce delirium, provide adequate sedation, reduce analgesic requirement, and concurrently improve cognitive performance.
Long-term objective: To standardize and compare different strategies of sedation and analgesia for ventilated ICU patients in order to optimize their clinical outcomes focusing on delirium and the long-term neuropsychological dysfunction of ICU survivors.
Specific Aims:
- to study prevalence and duration of delirium in critically ill patients using differential exposure to alpha2 vs. GABA receptor agonists while evaluating efficacy of sedation and analgesia;
- to compare clinical outcomes including duration of mechanical ventilation, ICU length of stay and severity of neuropsychological dysfunction at hospital discharge; and
- to develop pharmacokinetic and pharmacodynamic models for dexmedetomidine and lorazepam when used for up to 5 days in ICU patients.
Relationship to anesthesiology: We will study whether the adverse clinical outcomes associated with ICU delirium including long-term neuropsychological dysfunction can be modified by the choice of psychoactive agents frequently used by anesthesiologists and intensivists.
Design: A blinded, randomized controlled trial of adult mechanically ventilated patients using a sedation strategy of dexmedetomidine ± fentanyl versus lorazepam ± fentanyl, with relevant outcomes and safety monitoring.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexmedetomidineDrug
a bolus dose of 1 μg/kg infused over 10 minutes followed by an infusion started at 0.15- 0.45 μg/kg/hr. Dexmedetomidine will be titrated every 10 minutes to achieve set target RASS score. The maximum dexmedetomidine infusion will be 1.5 μg/kg/hr.
LorazepamDrug
Patients in the lorazepam arm will receive a bolus dose of 1-3 mg followed by an infusion started at 1-3 mg/hr. Lorazepam infusion will be titrated every 10 minutes to achieve set target RASS score. The maximum lorazepam infusion will be 10 mg /hr.
| Study group | Role | What they receive |
|---|---|---|
| Dexmedetomidine group | Active comparator | Patients in the dexmedetomidine arm will receive a bolus dose of 1 μg/kg infused over 10 minutes followed by an infusion started at 0.15- 0.45 μg/kg/hr. The patient's managing physician will have the option of beginning the dexmedetomidine infusion without a bolus in circumstances where the patient's sedation level is adequate at enrollment or in the presence of baseline bradycardia /hypotension. Dexmedetomidine will be titrated every 10 minutes to achieve set target RASS score. The maximum dexmedetomidine infusion will be 1.5 μg/kg/hr. Receives: Drug: Dexmedetomidine |
| Lorazepam group | Active comparator | Patients in the lorazepam arm will receive a bolus dose of 1-3 mg followed by an infusion started at 1-3 mg/hr. Lorazepam infusion will be titrated every 10 minutes to achieve set target RASS score. The maximum lorazepam infusion will be 10 mg /hr. Receives: Drug: Lorazepam |
What is being measured
The primary outcome is the main question the study is designed to answer.
achieving target sedation level
The patients' managing team will set the "goal" or "target" as medically indicated using the RASS 37. A trained research nurse or physician blinded to patients' group assignment and medical management will perform measurement of the "actual" RASS level every 12 hours. Comparisons will be made between the actual and target RASS levels to determine the primary outcome measure, which is the accuracy of achieving the target sedation level.
Measured: Patients will receive study drug for a maximum of 120 hours (5 days)
Secondary outcomes (1)
duration and severity of delirium
Delirium will be measured using the CAM-ICU, every 12 hours, by the same research personnel performing the assessment of the patients' sedation level. Together, these instruments take on average only 1 to 2 minutes to perform. Delirium is said to be present if the patients are responsive to verbal stimulation with eye opening (i.e., RASS -3 or better) and are found to have an acute change or fluctuation in the course of their mental status, inattention, and either disorganized thinking or an altered level of consciousness.
Measured: Patients will receive study drug for a maximum of 120 hours (5 days)

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Dexmedetomidine and Lorazepam in people with Delirium, run by Vanderbilt University at 1 site in United States.
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 1 inclusion and 19 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 11 Sep 2018. 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 United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
achieving target sedation level (time frame: Patients will receive study drug for a maximum of 120 hours (5 days)). 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 NCT00095251, which also lists 15 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 11 Sep 2018; AzTrials last refreshed its copy on 30 Oct 2026.
