Sub-Lingual Dexmedetomidine in Agitation Associated With Dementia — TRANQUILITY  

Dementia Clinical Trial

Official title: A Phase Ib/II, Multicenter, Randomized, Double Blind, Placebo Controlled, Ascending Dose Finding, Efficacy, Pharmacokinetic and Safety Study of BXCL501 In Agitation Associated With Dementia

Status Completed

Clinical Trial Summary

This is an adaptive Phase 1b/2 trial design. It is randomized, double-blind, placebo-controlled, multiple ascending dose study assessing efficacy, pharmacokinetics, safety and tolerability of BXCL-501 dosing in adult (65 years and older) males and females with acute agitation associated with dementia. Evaluation of 3 doses are planned.

Clinical Trial Description

This is a Phase 1b/2 randomized, double-blind, placebo controlled, ascending dose finding study assessing efficacy, pharmacokinetics, safety, and tolerability of BXCL501 with 3 dosing groups in adult (65 years and older) males and females with acute agitation associated with all forms of dementia. Evaluation of three (3) doses of sublingual BXCL 501 are planned. Cohort 1, Cohort 2 and Cohort 3 will be given 30µg, 60µg and 90µg dose respectively of BXCL501 or placebo. Subjects assigned to Cohort 3 will participate in a 1-week safety observation before being enrolled. This is an adaptive design as doses selected for testing may be different from these, based upon safety reviews. Doses lower or higher may be chosen to test, up to 180µg, and additional subjects may be added to a cohort. BXCL501 films may be divided in half if needed to deliver half-dose strengths. At least 30 subjects (10 per cohort) will be enrolled at up to 3 study sites in the United States. In Part B a total of 46 subjects will receive BXCL501 40 μg or matching placebo film. The effects of BXCL 501 on acute agitation will be assessed by the following scales: Pittsburgh Agitation Scale (PAS), the PANSS-EC (PEC), Cohen-Mansfield Agitation Inventory (CMAI), CGI-Severity for Agitation and CGI Improvement for Agitation. Adverse Events (AEs), clinical laboratory tests, ECG, and vital signs will be monitored, and all observed. ;
