- Registration Number
- NCT06093451
- Lead Sponsor
- Temple University
- Brief Summary
An open-label, randomized, active control inpatient trial to evaluate the efficacy and tolerability of sublingual dexmedetomidine for the treatment of agitation in inpatients with schizophrenia or bipolar disorder as measured by the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC) and Agitation-Calmness Evaluation Scale (ACES). Lorazepam will serve as the active control.
- Detailed Description
This is an open-label, randomized control trial where patients (N=32) with schizophrenia or bipolar disorder are randomized to receive either sublingual dexmedetomidine or oral lorazepam monotherapy for the treatment of episodic agitation. For moderate agitation (PANSS-EC score ≥14 and \<20), patients will receive either sublingual dexmedetomidine 120mcg or oral lorazepam 2mg. For severe agitation (PANSS-EC ≥20), patients will receive either sublingual dexmedetomidine 180mcg or oral lorazepam 2mg. The PANSS-EC and ACES will be evaluated at baseline and after 15, 30, 60, and 120 minutes.

Group Intervention Description Lorazapem Lorazepam 2 MG/ML Participants with moderate agitation will receive oral lorazapam 2 mgas needed. Participants with severe agitation will receive oral lorazapam 2 mg as needed. Dexmedetomidine Dexmedetomidine Participants with moderate agitation will receive sublingual dexmedetomidine 120 mcg as needed. Participants with severe agitation will receive dexmedetomidine 180 mcg as needed.
- Primary Outcome Measures
Name Time Method Change in PANSS-EC score at 120 minutes after medication administration Baseline and at 120 minutes Severity of agitation will be determined by administering the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC). Moderate to severe agitation will be defined as a PANSS-EC score \>=14 and \<20; and \>= 20 is severe agitation.
- Secondary Outcome Measures
Name Time Method Change from baseline in ACES score at 15, 30, 60, 90, and 120 minutes, or prior to receipt of any rescue medication for agitation. Baseline and 15, 30, 60, 90, and 120 minutes Severity of agitation will be measured using the standardized Agitation-Calmness Evaluation Scale. The 9-point scale indicated the degree of agitation as follows: 1=marked agitation, 4=normal behavior, 7 = marked calmness, 9=unarousable.
Assess the need for rescue medication for agitation within two hours of medication administration Baseline and 2 hours after medication administration Need for rescue medication of sublingual dexmedetomidine will be assessed by reviewing the Medication Administration Reconciliation (MAR) available on the electronic medical record system for the two hour period of time following medication administration.
Patient tolerability assessed by adverse events of dexmedetomidine Baseline through 120 minutes after medication administration Tolerability and safety of sublingual dexmedetomidine was assessed by evaluating spontaneously-reported adverse events. Treatment tolerability as assessed by adverse events will be tabulated by toxicity grade and organ systems as well as overall.
Change in PANSS-EC score at 15, 30, 60, and 90 minutes, or prior to receipt of any rescue medication for agitation. Baseline and 15, 30, 60, and 90 minutes Severity of agitation will be determined by administering the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC). Moderate to severe agitation will be defined as a PANSS-EC score \>=14 and \<20; and \>= 20 is severe agitation.
Patient satisfaction based on Medication Satisfaction Questionnaire (MSQ) Administered 120 minutes after medication administration Medication Satisfaction Questionnaire (MSQ) will be given to the subject to assess their satisfaction of their agitation medication two hours after initial medication administration. The Medication Satisfaction Questionnaire is a 7-point scale, with 1 being "Extremely Dissatisfied", 4 being "Neither Satisfied or Dissatisfied", and 7 being "Extremely Satisfied"
