- Brief Summary
This study will examine the safety and efficacy of BXCL501 to reduce ASR symptoms and behavioral changes among patients presenting to the Emergency Department (ED) after Motor Vehicle Collision (MVC). Specifically, the investigators will perform the BXCL501 (BASIS) Trial, a double-blind placebo-controlled Randomized Controlled Trial (RCT) to determine if BXCL501 (dexmedetomidine hydrochloride sublingual film) initiated in the ED in the hours after MVC to high risk individuals, treats/reduces ASR/ASD symptoms (primary outcome), improves neurocognitive function, and prevents/reduces posttraumatic stress (PTS) symptoms (secondary outcomes) long term. 100 participants will be randomized, receive study drug in ED and be discharged with a 2-week drug supply. Prior to initial dose of study drug administration, and during the hours, days, and weeks after participants will receive serial longitudinal assessments of psychological and somatic symptoms, neurocognitive function, and adverse events.
- Detailed Description
U.S. military personnel are exposed to life-threatening traumatic events (e.g., intense firefights with multiple casualties) that result in acute stress reaction (ASR) symptoms (ICD-10) and posttraumatic stress (PTS). Similarly, acute and persistent stress symptoms, and related adverse posttraumatic neuropsychiatric sequelae, are also very common and cause a tremendous burden of suffering in civilian populations following exposure to life-threatening traumatic events (e.g., motor vehicle collision, violent or accidental death of a loved one, and assault). BXCL501 (dexmedetomidine HCl sublingual film) has been evaluated in multiple clinical trials across a range of medical conditions (dementia, schizophrenia, bipolar disorder, opioid use disorder), with an excellent safety profile, and evidence of efficacy with respect to decreasing agitation. This is promising for the treatment of ASRs, as agitation is a primary feature of ASRs in many individuals. Additionally, adrenergic hyperactivity is also a key characteristic of ASRs and contributes to the development of Posttraumatic Stress Disorder (PTSD). BXCL501 is known to decrease the activity of central noradrenergic neurons, suggesting a mechanistic pathway by which BXCL501 may improve outcomes for individuals at risk of ASR/ASD/PTSD. BXCL501 therefore holds significant promise as a treatment aimed at reducing ASR symptoms and related behavioral changes, enhancing resilience and improving warfighter performance, and reducing the frequency and severity of persistent/chronic PTS symptoms. This study will evaluate the safety and efficacy of BXCL501 in a population of trauma survivors at high risk for developing ASR, ASD, and PTSD symptoms, and may ultimately provide military personnel, veterans, and civilians with an important new treatment option to improve recovery, job performance, and quality of life when administered in the early aftermath of exposure to a traumatic stressor.

Group Intervention Description BXCL501 (dexmedetomidine HCl) BXCL501 (dexmedetomidine HCl) Participants will be instructed to take an initial dose of BXCL501 (equivalent to 1 film, 120mcg) in the ED as part of enrollment procedures. If the time between the first dose and the planned bedtime of the participant is greater than 6 hours, participants will be instructed to take the second dose at bedtime on the day of enrollment. If the time between the first dose and the planned bedtime of the participant is less than 6 hours participants will be instructed to take the second dose before bedtime on the day following enrollment. Following the initial dosing on the day of enrollment, all participants will be instructed to take a dose of study medication before bedtime until they have completed 14 days of treatment. Placebo Placebo Participants will be instructed to take an initial dose of placebo (equivalent to 1 film, 120mcg) in the ED as part of enrollment procedures. If the time between the first dose and the planned bedtime of the participant is greater than 6 hours, participants will be instructed to take the second dose at bedtime on the day of enrollment. If the time between the first dose and the planned bedtime of the participant is less than 6 hours participants will be instructed to take the second dose before bedtime on the day following enrollment.

- Primary Outcome Measures
Name Time Method Change in ASD Score Week 1, 3 after MVC Individuals are asked to complete the 14-item Acute Stress Disorder Scale (ASDS) self-report inventory where each item is rated on a 5-point scale (0= Not at all; 1= Mildly; 2= Medium; 3= Quite a bit; 4= Very Much) that indexes acute stress disorder (ASD). Range of possible total scores is 0-56, with higher total scores indicating greater acute stress symptoms.
- Secondary Outcome Measures
Name Time Method Median reaction time of correct responses (general cognitive function) Min 30, Hour 1, 6, 12, Day 1, 2, 3, Week 1, 2, 3, 5, 6, 8, 11, 12 after MVC General cognitive function will be assessed using the Test My Brain Digit Symbol Matching Test. Participants will be asked to match symbols and numbers using a symbol-number key shown on screen. General cognitive function is assessed via measuring median reaction time of correct responses (medianRTc) to 'test' trials. Range for medianRTc (ms) is 0-30000.
Median reaction time of correct responses (procedural reaction time) Min 30, Hour 1, 6, 12, Day 1, 2, 3, Week 1, 2, 3, 5, 6, 8, 11, 12 after MVC Procedural reaction time will be assessed using the Test My Brain Choice Reaction Time Test. Participants see a set of three arrows, where one arrow is a different color from the rest. The participant presses left or right to indicate the direction of the odd colored arrow. Reaction time is assessed via measuring median reaction time of correct responses (medianRTc) to 'test' trials. Range for medianRTc (ms) is 0-5000.
Proportion of targets correctly identified (visuospatial processing and attention) Min 30, Hour 1, 6, 12, Day 1, 2, 3, Week 1, 2, 3, 5, 6, 8, 11, 12 after MVC Visuospatial processing and attention will be assessed using the Test My Brain Multiple Object Tracking Test. In this test of visuospatial processing and attention, participants have to track a set of target circles around the screen (amidst a field of distractors) that move at increasing speed with each trial. Once the circles stop moving, participants select which were targets must identify targets instead of distractors. Visuospatial processing and attention are assessed via the proportion of targets correctly identified. Range for measure is 0-1.
d-prime identification (psychomotor vigilance) Min 30, Hour 1, 6, 12, Day 1, 2, 3, Week 1, 2, 3, 5, 6, 8, 11, 12 after MVC Psychomotor vigilance will be assessed via the Test My Brain Gradual Onset Continuous Performance Test. In this task, participants monitor a stream of city and mountain images that rapidly fade from one to the next with no interstimulus interval. Participants are asked to press/touch for each city image and to withhold for each mountain image. Vigilance is assessed via measuring d-prime for identification of each city image, a signal detection-based measure that takes into account both hits and false alarms to provide an unbiased estimate of performance where higher values reflect better performance. Response inhibition is defined as the suppression of actions that are inappropriate in a given context. Response inhibition is assessed using results from the above, by measuring the number of commission errors (failure to withhold responses) where most positive scores reflect more impulsive responding. Range for measure is -4.2279 to 4.2279.
Change in Pain Symptom Score Baseline, Week 1, 3, 6, 12 after MVC The Regional Pain Scale (RPS) will be used to assess the extent of body pain. 13 items will be scored on a 0-10 pain scale where 0 is no pain and 10 is severe pain. Range of possible total scores is 0-130, with higher total scores indicative of greater pain symptoms
Change in Depressive Symptoms Score Baseline, Week 1, 3, 6, 12 after MVC The Patient-Reported Outcomes Measurement Information System (PROMIS) Depression Short Form 8b; an 8-item scale, and one question from the PROMIS Depression Item Bank will be aggregated/combined to assess depression. Each item is scored on a 5-point scale where 0 is "none of the time" and 5 means "all or almost all of the time". Range of possible total scores is 0-45, with higher total scores indicative of greater depressive symptoms.
Change in Somatic Symptom Score Baseline, Week 1, 3, 6, 12 after MVC The Pennebaker Inventory of Limbic Languidness (PILL) assesses the frequency of common physical symptoms and sensations. The investigators will use a version with adapted response options for greater consistency across measures, greater precision in response levels, and to allow administration via self-report. 20 items will be scored on a 0-10 scale where 0 is "no problem" and 10 means "major problem". Range of possible total scores is 0-200, with higher total scores indicative of greater somatic symptoms.
Change in PTSD Symptoms Baseline, Week 1, 3, 6, 12 after MVC The PTSD Checklist for DSM-5 (PCL-5) assesses PTSD symptoms as defined by the Diagnostic and Statistical Manual of Mental Disorders-5th Edition (DSM-5). 20 items will be scored on a five-point scale ranging from 0 ("not at all") to 4 ("extremely"). Range of possible total scores is 0-80, with higher total scores indicative of greater PTSD symptoms.
