Tachyphylaxis, Tolerance, & Withdrawal Post Treatment With Igalmi for Agitation in Schizophrenia or Bipolar Disorder

BioXcel Therapeutics Inc29 enrolled

Overview

This is an in-clinic, single arm, open-label study assessing tachyphylaxis, tolerance, and withdrawal following repeated doses of Igalmi in adult males and females with agitation associated with schizophrenia or bipolar disorder.

This is an in-clinic, single arm, open-label study assessing tachyphylaxis, tolerance, and withdrawal following repeated doses of Igalmi in adult males and females (18 to 65 years old, inclusive) with agitation associated with schizophrenia or bipolar disorder. Subjects will be screened for eligibility within 15 days of first dose and no study procedures will occur unless subjects provide written informed consent. Subjects will receive single doses of 180 μg of Igalmi as needed for the treatment of agitation over a period of 7 days followed by a 3- day follow-up period during which time no Igalmi will be administered in an effort to characterize any potential withdrawal. Subjects will sublingually self-administer Igalmi for an agitation episode that reaches a pre-dose PEC total score of 14 or greater, as determined by a trained rater. Safety assessments will be conducted before and after each dose. If the subject's agitation is recurrent or persistent, repeat doses of 90 µg may be administered (no more than 2 repeat doses within a 24-hour period) in the absence of any safety concerns or adverse events.

Outcomes

Primary Outcomes

Change From Baseline in the Positive and Negative Syndrome Scale- Excited Component (PEC) Total Score

The Positive and Negative Syndrome Scale-Excited Component (PEC) includes 5 items-poor impulse control, tension, hostility, uncooperativeness, and excitement-each of which is rated from 1 (minimum) to 7 (maximum); the sum of these 5 items, the PEC total score, ranges from 5 (absence of agitation) to 35 (extremely severe).

Time frame: Baseline and 2 hours post-dose for all doses administered over 7 days.

Clinical Global Impression - Improvement (CGI-I)

The Clinical Global Impression - Improvement (CGI-I) for agitation in response to treatment measures the current level of agitation relative to the level of agitation prior to administration of study intervention. The CGI-I scores range from 1 to 7 with a score of 1 indicating very much improved, and a score of 7 indicating very much worse.

Time frame: 2 hours post-dose for all doses administered over 7 days.

Secondary Outcomes

Number of Participants With Adverse Events During the Follow-up Period

Evaluation of withdrawal phenomenon based on the occurrence of adverse events such as tachycardia, systolic hypertension, nausea, or vomiting and the emergence of any new adverse events on ≥2 consecutive days of the 3-day off-treatment follow-up period.

Time frame: Day 8 through Day 10
