Treating Acutely Agitated Patients With Asenapine Sublingual Tablets

Unity Health Toronto120 enrolled

Overview

Our proposal is to administer asenapine to patients who are clinically agitated and in need of immediate intervention. At present there are no controlled studies that we know of that explores the use of asenapine for this purpose. Establishing the utility of asenapine for this common clinical problem will support its use as an additional treatment option in acutely agitated patients.

A psychiatrist (blinded) will assess the patient for agitation and their capacity to consent. Patients will be informed about the study and asked to complete informed consent prior to being included in the study. Patients who decline will not be included. A nurse (blinded) will administer either 10mg asenapine or placebo sublingually in a randomized fashion. Efficacy in reducing acute agitation will be evaluated using the PANSS-EC. A trained rater (blinded) will rate patients at baseline and at 15, 30, 60, 90 and 120 minutes (or endpoint) after medication administration. Efficacy in reducing acute agitation will also be evaluated using the Clinical Global Impression Scale (CGI). A trained rater (blinded) will rate patients at baseline CGI-Severity and CGI-Change at 60 and 120 minutes (or endpoint) after medication administration. The need for additional medications, interventions or physical restraints will be recorded and constitute the endpoint for that patient. Demographics, diagnoses, blood alcohol level, urine toxicology, and urine pregnancy will be collected.

Outcomes

Primary Outcomes

Positive and Negative Syndrome Scale - Excited Component

The primary outcome measure is change in the Positive and Negative Syndrome Scale - Excited Component (PANSS-EC) from baseline to 2 hours after medication administration. The PANSS-EC consists of 5 items: excitement, tension, hostility, uncooperativeness, and poor impulse control. The 5 items from the PANSS-EC are rated from 1 (not present) to 7 (extremely severe); scores range from 5 to 35; mean scores ≥ 20 clinically correspond to severe agitation. This set of items detects differences between drug and placebo when evaluating acute agitation and aggression in psychiatric patients with different psychiatric pathologies.

Time frame: Change in PANSS-EC score from baseline to 2 hours post drug/placebo administration.

Secondary Outcomes

Clinical Global Impression Scale

Secondary outcome measures will include the Clinical Global Impression -Severity (CGI-S) and Clinical Global Impression-Improvement (CGI-I) scales.

Time frame: 2 hours
