Trial Summary

Will I have to stop taking my current medications?

The trial requires you to stop taking certain medications, including those for alcoholism, some sedative antidepressants, and specific blood pressure medications. However, non-sedative antidepressants for PTSD are allowed.

What data supports the effectiveness of the drug BXCL501 for treating acute stress disorder?

The research suggests that drugs blocking norepinephric hyperactivity, like prazosin, show promise in treating stress-related conditions such as PTSD. This indicates that similar mechanisms might be effective for acute stress disorder, potentially supporting the use of BXCL501 if it has similar properties.12345

Is BXCL501 safe for humans?

There is no specific safety data available for BXCL501 in the provided research articles.24678

What is the purpose of this trial?

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.

Treatment Details

Interventions

  • BXCL501
Trial Overview The study tests BXCL501, a medication given under the tongue, against a placebo to see if it can reduce symptoms of acute stress reaction and prevent long-term post-traumatic stress after a car accident. It's a double-blind study with 100 participants.
Participant Groups
2Treatment groups
Experimental Treatment
Placebo Group
Group I: BXCL501 (dexmedetomidine HCl)Experimental Treatment1 Intervention
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.
Group II: PlaceboPlacebo Group1 Intervention
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. 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.

Findings from Research

Cognitive-behavioral interventions have shown positive effects for treating Acute Stress Disorder (ASD), while psychodynamic therapy, cognitive-behavioral therapy, and EMDR are promising for Posttraumatic Stress Disorder (PTSD).
Selective Serotonin Reuptake Inhibitors (SSRIs) are the most studied and effective medications for both ASD and PTSD, offering a broader therapeutic effect and better tolerance compared to tricyclic antidepressants.
