What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new treatment, BNC210, to determine its effectiveness in reducing anxiety in individuals with social anxiety disorder. Researchers aim to discover if a single dose of BNC210 can lower anxiety during a specific task compared to a placebo (a pill with no active drug). Participants officially diagnosed with social anxiety disorder and who frequently experience anxiety in social situations might be suitable candidates. As a Phase 3 trial, this study serves as the final step before FDA approval, providing participants an opportunity to contribute to a potentially groundbreaking treatment for social anxiety disorder.

Will I have to stop taking my current medications?

Yes, you will need to stop taking psychotropic medications (drugs that affect your mind, emotions, and behavior) at least 30 days before the screening, and you must not use benzodiazepines daily for 90 days before the screening.

Is there any evidence suggesting that BNC210 is likely to be safe for humans?

Research has shown that BNC210 is usually well-tolerated. In earlier studies, individuals who took BNC210 for anxiety-related issues, such as panic attacks and generalized anxiety disorder, tolerated it well. These studies found that BNC210 quickly and effectively reduced anxiety without causing major side effects. However, as with any treatment, some people might experience side effects. Consulting healthcare professionals is important to understand the possible risks and benefits before joining a trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Most treatments for social anxiety disorder, like SSRIs and SNRIs, work by increasing serotonin or norepinephrine levels in the brain, which can take weeks to show effects. But BNC210 works differently, targeting the brain's GABA receptors to potentially reduce anxiety faster. Researchers are excited about BNC210 because it might offer quicker relief without the sedation and dependency issues of benzodiazepines. This unique mechanism of action could make BNC210 a promising alternative for those seeking rapid symptom relief.

What evidence suggests that BNC210 might be an effective treatment for social anxiety disorder?

Research has shown that BNC210, which participants in this trial may receive, might help treat social anxiety disorder. Studies found that just one dose of BNC210 lowered anxiety symptoms, measured using a simple scale that rates anxiety levels. In clinical trials, people who took BNC210 felt less anxious than those who took a placebo. These results suggest that BNC210 could be a good option for reducing anxiety in social situations. ^{1 2 5 6 7}

In an 8-week study involving 12 patients with social anxiety disorder, olanzapine showed significant improvement compared to placebo on key anxiety measures, indicating its potential efficacy as a treatment.

Both olanzapine and placebo were well tolerated, with olanzapine causing more drowsiness and dry mouth but negligible weight gain, suggesting a favorable safety profile for further investigation.

A new, comprehensive treatment for severe social phobia has shown effectiveness in a pilot study, particularly for individuals with co-occurring mental health conditions.

The treatment resulted in significant improvements across various outcome measures, highlighting the importance of a multifaceted approach to effectively address social phobia.

A systematic review of 51 randomized controlled trials involving 9914 participants found that pharmacotherapy for social anxiety disorder (SAD) is effective, with over 55% of participants responding positively to treatment after an average of 12 weeks.

Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) were identified as the most effective and well-tolerated medication classes for SAD, while beta-blockers showed insufficient evidence for treating performance anxiety.

A systematic review of 27 clinical trials involving second-generation antidepressants (SGA) showed that these medications significantly reduce symptoms of social anxiety disorder (SAD) compared to placebo, with a mean reduction in Liebowitz Social Anxiety Scale scores of -11.9.

The analysis indicated a 62% increase in treatment response for patients using SGAs, but no significant differences in efficacy were found among the various second-generation antidepressants tested.

In a 12-week open trial with 21 patients suffering from social phobia, buspirone showed modest efficacy, with 47% of participants rated as much to very much improved in their symptoms by the end of the study.

Among those who tolerated higher doses of 45 mg/day or more, 67% experienced significant improvement, indicating that higher doses may enhance the treatment's effectiveness for social phobia.

Patients with early-onset social anxiety disorder (SAD) are more likely to experience inactivity, have a generalized subtype of social phobia, and present with psychiatric comorbidities compared to those with late-onset SAD, indicating a distinct clinical profile.

Despite these differences in presentation, both early-onset and late-onset patients showed similar severity of symptoms and therapeutic responses after at least ten weeks of drug treatment.

Selective serotonin reuptake inhibitors (SSRIs) are currently considered the first-line treatment for social anxiety disorder due to their proven safety, tolerability, and efficacy.

Other medications like clonazepam, bromazepam, and gabapentin show potential efficacy similar to SSRIs, but more research is needed to confirm their effectiveness, while phenelzine is reserved for cases that do not respond to SSRIs.

Social anxiety disorder (SAD) is a chronic condition that often begins in adolescence and can persist throughout life if untreated, with a significant number of patients also experiencing comorbid mental health issues.

Selective serotonin reuptake inhibitors (SSRIs) have emerged as the first-line treatment for SAD due to their proven safety, tolerability, and efficacy, while ongoing research aims to improve treatment outcomes and prevent relapse.

In a study of 200 bipolar disorder patients, 17.5% were found to have comorbid social anxiety disorder (SAD), which was linked to more severe episodes and an earlier onset of bipolar disorder.

Despite the increased severity of episodes in patients with SAD, there was no significant difference in treatment response to mood stabilizers like lithium and anticonvulsants between those with and without SAD.
