Trial Outcomes & Findings for Sub-Lingual Dexmedetomidine in Agitation Associated With Dementia (NCT NCT04251910)

NCT ID: NCT04251910

Last Updated: 2023-09-21

Results Overview

The change in PEC score was evaluated at 2 hours following the administration of the BXCL501 60 mcg, and BXCL501 30 mcg (for Part A) and BXCL501 40 mcg (for Part B) versus placebo. PEC is the sum of 5 subscales (poor impulse control, tension, hostility, uncooperativeness, and excitement, each subscale ranging from 1 to 7) and thus ranges from 5 to 35. Change from baseline (pre-dose) PEC total score, with negative values is in favor of improvement.

SECONDARY outcome

Timeframe: Baseline and at 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, 24 hours, Day 3, Day 7 post-dose

Population: The Intent to Treat Population consisted of all patients in the Safety Population who have a baseline and at least one post-baseline efficacy assessment.

The onset and magnitude of calming effects of different doses of BXCL501 on symptoms of acute agitation associated with dementia was described as measured by the PAS. The PAS is an instrument that measured 4 behaviors namely: aberrant vocalization, motor agitation, aggressiveness and resisting to care. The patients are evaluated on a scale of 0 to 4, where 0 indicated no agitation and 4 indicated highest form of agitation. The PAS total score ranges from 0 to 16. Higher scores mean a worse outcome. Change in value of PAS total score, with negative value indicated the improvement in condition of the patients.

SECONDARY outcome

Timeframe: Baseline and 1 hour, 2 hours, 4 hours, 8 hours post-dose

Population: The Intent to Treat Population consisted of all patients in the Safety Population who have a baseline and at least one post-baseline efficacy assessment. Here, number analyzed in each row signifies only the patients with available data that were analyzed for change in ACES score.

To evaluate the change in the total score of ACES from baseline to 8 hours post administration of 30 mcg, 60 mcg and 40 mcg compared to placebo. The ACES is a single item measure rating overall agitation and sedation which ranges from 1 to 9, where 1 indicates marked agitation, 2 - moderate agitation; 3 - mild agitation; 4 - normal behavior; 5 - mild calmness; 6 - moderate calmness; 7 - marked calmness; 8 - deep sleep; and 9 - unarousable. Change from baseline (pre-dose) ACES total score, with negative values in favor of improvement.

SECONDARY outcome

Timeframe: Baseline and at 2 hours, and 24 hours post-dose

Population: The Intent to Treat Population consisted of all patients in the Safety Population who have a baseline and at least one post-baseline efficacy assessment.

The CGI-S was based upon the severity of agitation. It was assessed based on the following scale: 0 = Not assessed; 1 = Normal not at all symptomatic; 2 = Minimally symptomatic- few or mild symptoms -little interference with patients functioning; 3 = Mildly symptomatic-low level of symptoms-little interference in social functioning; 4 = Moderately symptomatic-some prominent symptoms-some interference in functioning; 5 = Markedly symptomatic-significant symptoms with very substantial interference in functioning; 6 = Severely symptomatic- very marked symptoms make it difficult for patients to engage with others; 7 = Among the most extremely symptomatic patients-extreme symptoms -patient is incapacitated or highly dangerous to self or others requires extra care and supervision. The higher the score, the higher is the severity of the agitation and lesser the score, the lower the agitation. Change from baseline CGIS total score, with negative values in favor of improvement.

SECONDARY outcome

Timeframe: 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours post-dose

Population: The Intent to Treat Population consisted of all patients in the Safety Population who have a baseline and at least one post-baseline efficacy assessment. Here, number analyzed in each row signifies only the patients with available data that were analyzed for CGI-I agitation score.

To evaluate the CGI-I agitation score at 30 minutes, 1 hour, 2 hours, and 8 hours after administration of 30 mcg, 60 mcg and 40 mcg of BXCL501 compared to placebo. The CGI-I scores range from 1 to 7 comprise of 0 = Not assessed (missing), 1 = Very much improved, 2 = Much improved, 3 = Minimally improved, 4 = No change, 5 = Minimally worse, 6 = Much worse, 7 = Very much worse. The lower score (1) indicated the improvement in the condition of patient and higher score (7) indicates the worsening of the condition. Straight CGI-I total score, with lower values in favor of improvement.

SECONDARY outcome

Timeframe: Baseline and at 2 Hours and Day 7 post-dose

Population: The Intent to Treat Population consisted of all patients in the Safety Population who have a baseline and at least one post-baseline efficacy assessment.

To evaluate the change in Cohen Mansfield Agitation Inventory (CMAI) total score from baseline after 2 hour and on Day 7 post administration of 30 mcg, 60 mcg and 40 mcg BXCL501 compared to placebo. The CMAI is a rating which is comprised of 29 behaviors each rated on a 7-point scale of frequency. A total CMAI score is obtained by summing all the individual items, giving a range from 29 to 203. Change from baseline (pre-dose) CMAI total score, with negative values in favor of improvement in the condition of the patients.
