Safety, Tolerability and Efficacy of RGH-202 in Social Anxiety Disorder (STAGE) (STAGE)

2026年11月5日 更新者：Gedeon Richter Plc.

A Phase 2a, Multicenter, Randomized, Double-blind, Two-arm, Placebo-controlled Clinical Trial to Assess the Safety, Tolerability and Efficacy of RGH-202 for the Management of Performance and Social Interaction Anxiety in Adults With Social Anxiety Disorder

The reason for this trial is to see if the investigational product, called RGH-202, is safe and well tolerated, and can help people with social anxiety disorder.

The main questions this study aims to answer are:

  • Is RGH-202 safe and well tolerated in adults with social anxiety disorder?
  • Does RGH-202 reduce symptoms of social anxiety disorder compared with placebo? RGH-202 will be compared with a placebo (a product that does not contain any active ingredients) to determine whether the investigational medicine may be an effective treatment for SAD.

Participants will have an equal chance of receiving RGH-202 or the placebo taken for 6 weeks.

Participants will attend regular clinic visits for safety assessments, study evaluations and complete questionnaires related to their social anxiety symptoms.
