Celecoxib for Major Depressive Disorder
Trial Summary
What is the purpose of this trial?
Major depressive disorder (MDD) affects an estimated 350 million people worldwide and is a leading contributor to global disease burden. Commonly used monoamine reuptake-inhibiting treatments for depression are suboptimal, resulting in only 30% of patients achieving remission. This may be because monoamine dysfunction is not the primary pathophysiology in all MDD patients. One avenue for the development of novel MDD treatments is through anti-inflammatory drugs; MDD is linked to a pro-inflammatory phenotype characterized by microglial activation, leading to the release of pro-inflammatory cytokines and upregulation of cellular markers including cyclooxygenase-2 (COX-2) and translocator protein (TSPO; a protein located on the outer membrane of microglia). Relevant to this proposal, TSPO can serve as an in vivo marker of neuroinflammation using the newly developed positron emission tomography (PET) tracer for TSPO, \[18F\]FEPPA. In support of this, a recent \[18F\]FEPPA PET study found that MDD patients in a current major depressive episode (MDE) had significantly higher TSPO binding in the prefrontal cortex (PFC), anterior cingulate cortex (ACC) and insula, relative to healthy controls. The prefrontal cortex and ACC are both implicated in mood regulation whereas the insula is involved in interoceptive signaling, which is known to be abnormal in MDD. Celecoxib, a selective COX-2 nonsteroidal anti-inflammatory drug (NSAID), is a promising new treatment for neuroinflammation in MDD. Clinical studies have observed that, in a subset of depressed patients, celecoxib treatment reduced depression severity as assessed by the Hamilton Depression Rating Scale (HDRS). While these findings demonstrate that celecoxib reduces symptom severity, PET imaging technology is critical for understanding how celecoxib affects the underlying pathophysiology of depression. Here, the team will investigate neuroinflammation as an underlying pathology in depression and test whether neuroinflammation is reduced by celecoxib in MDD patients. Specifically, in the proposed pilot study, MDD patients in a current MDE will receive \[18F\]FEPPA PET scans prior to and following 8 weeks of treatment with 400mg/day of celecoxib, with HDRS scores obtained at each time point. The investigators hypothesize that following celecoxib treatment, patients will show a significant reduction in neuroinflammation in the PFC, ACC and insula, which will correlate positively with the reduction in depressive symptoms, as measured by the HDRS. The proposed study will use novel imaging technology, \[18F\]FEPPA PET, to measure the effects of celecoxib on neuroinflammation in MDD patients. Our results will help to 1) identify neuroinflammation as an underlying pathology in MDD and 2) test whether reduction of inflammation is the mechanism of action of celecoxib. As such, the results of this study will aid in the development of targeted clinical treatments to improve remission rates in MDD patients.
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 medications that interact with celecoxib or have anti-inflammatory or immune-modulating effects. There is also a required period without these medications before starting celecoxib.
What data supports the effectiveness of the drug Celecoxib for treating Major Depressive Disorder?
Research shows that adding Celecoxib to standard antidepressant treatment can lead to greater improvement in depression symptoms compared to antidepressants alone. This suggests that Celecoxib, which reduces inflammation, may help treat depression by addressing inflammation-related aspects of the disorder.12345
Is Celecoxib safe for use in humans?
Celecoxib, also known as Celebrex, is generally considered safe for humans when used at the lowest effective dose for the shortest time. It has fewer stomach-related side effects compared to other similar drugs, but it may increase the risk of heart problems, especially at higher doses. People with heart issues or allergies to sulfonamides should be cautious, and it's important to discuss potential risks and benefits with a doctor.678910
How does the drug celecoxib work differently for major depressive disorder?
Celecoxib is unique for treating major depressive disorder because it works by reducing inflammation in the body, specifically by inhibiting pro-inflammatory substances like interleukin-6 (IL-6). This anti-inflammatory action is different from traditional antidepressants, which typically target neurotransmitters in the brain.1351112
