The Effect of Celecoxib on Neuroinflammation in MDD: PET Imaging of a Novel Treatment Target with [18F]FEPPA

Phase 4 Interventional Stony Brook University · NCT04814355

This study is testing whether the anti-inflammatory medication celecoxib can help people with major depressive disorder feel better, especially those who haven't found relief from regular antidepressants.

What this trial studies

This clinical trial investigates the impact of celecoxib, an anti-inflammatory medication, on neuroinflammation in patients diagnosed with major depressive disorder (MDD). The study aims to explore whether reducing neuroinflammation can improve depressive symptoms, particularly in individuals who do not respond to traditional antidepressant therapies. Participants will be assessed using positron emission tomography (PET) imaging to measure neuroinflammation levels before and after treatment with celecoxib. The trial focuses on patients currently experiencing a major depressive episode and evaluates the medication's safety and efficacy in this context.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-65 who have been diagnosed with major depressive disorder and are currently experiencing a major depressive episode.

Not a fit: Patients with contraindications to celecoxib or those currently taking medications that interact with it may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with major depressive disorder who do not respond to existing therapies.

How similar studies have performed: Other studies have indicated a potential link between neuroinflammation and depression, suggesting that anti-inflammatory treatments like celecoxib may offer new avenues for effective management of MDD.
