What is the purpose of this trial?

This trial explores a new treatment called BXCL501, a potential medication to help manage stress and behavior changes after a car crash. The focus is on reducing acute stress reactions (the body's immediate response to trauma) and improving mental function and long-term stress symptoms. Participants will take the treatment shortly after visiting the emergency room and continue it for two weeks. Suitable candidates have visited the emergency room within 24 hours of a car accident and are expected to go home from there. As a Phase 2 trial, the research measures the treatment's effectiveness in an initial, smaller group of people.

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.

Is there any evidence suggesting that BXCL501 is likely to be safe for humans?

Research has shown that BXCL501, also known as dexmedetomidine hydrochloride, is generally safe for people. One study found that BXCL501 was well-tolerated even when taken with alcohol. Another study suggested it could help treat conditions like PTSD and alcohol use disorder without major safety issues.

The safety of a 120 mcg dose of BXCL501, the same dose used in this trial, has been tested in other studies. These studies did not find any significant side effects, indicating that the treatment is well-tolerated. Since this trial is in an early phase, some safety data is available, but more research is needed to fully confirm its safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for acute stress disorder?

Unlike the standard treatments for Acute Stress Disorder, such as benzodiazepines and SSRIs, BXCL501 is a film containing dexmedetomidine HCl that dissolves under the tongue. This medication is unique because it targets the brain's alpha-2 adrenergic receptors, offering a calming effect without the sedation typically associated with other treatments. Researchers are excited about this treatment because it promises rapid relief from stress symptoms, potentially showing effectiveness in just days rather than weeks. Additionally, the sublingual delivery method is easy to use and avoids the need for injections or pills.

What evidence suggests that BXCL501 might be an effective treatment for Acute Stress Disorder?

This trial will compare BXCL501, a film that dissolves under the tongue, with a placebo. Studies have shown that BXCL501 can help reduce stress-related behaviors. Research indicates it may be effective for people who have experienced high stress, such as after a car accident. In previous studies, BXCL501 significantly reduced stress symptoms compared to a placebo. This suggests it could potentially help reduce immediate stress reactions and improve recovery after a traumatic event. ^{1 2 4 6 7}

What Are the Treatments Tested in This Trial?

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.

How Is the Trial Designed?

Group I: BXCL501 (dexmedetomidine HCl) Experimental Treatment 1 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: Placebo Placebo Group 1 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.

Published Research Related to This Trial

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.
