Trial Summary

What is the purpose of this trial?

This trial tests Vraylar® to see if it can help people with social anxiety disorder by balancing brain chemicals related to mood and anxiety. Current treatments are not effective for everyone and often have side effects, so new options are needed.

Will I have to stop taking my current medications?

Yes, you will need to stop taking certain medications before joining the trial. Specifically, you cannot take fluoxetine within 28 days of starting, and you must stop taking other psychotropic medications like SSRIs, SNRIs, and benzodiazepines at least 14 days before the trial begins.

How does the drug Cariprazine differ from other drugs for social anxiety disorder?

Cariprazine is unique because it is primarily used as an antipsychotic for conditions like schizophrenia and bipolar disorder, and its use for social anxiety disorder is novel. Unlike traditional treatments for social anxiety, which often include antidepressants or benzodiazepines, Cariprazine works by targeting dopamine receptors, which may offer a different approach to managing symptoms. ^{1 2 3 4 5}

Findings from Research

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.
