What this trial studies

This clinical trial investigates the effectiveness of Roflumilast as an additional treatment for patients with Major Depressive Disorder (MDD) who are already receiving antidepressants. The study aims to determine if combining Roflumilast with Fluoxetine can enhance therapeutic outcomes for patients who do not respond adequately to standard antidepressant therapy. Participants will be assessed based on their depression severity using the Hamilton Depression Rating Scale (Ham-D). The trial will involve a comparison between the combination treatment and a placebo.

Why it matters

Potential benefit: If successful, this approach could provide a new treatment option for patients with Major Depressive Disorder who do not respond to existing antidepressants.

How similar studies have gone: While the combination of medications for MDD is a common approach, the specific use of Roflumilast in this context is novel and has not been extensively tested in prior studies.
