About this trial
This is an experimental study designed to measure the effect of celecoxib or minocycline on depressive symptoms in unipolar and bipolar depression. Participants will be equally randomized to either celecoxib or minocycline. All participants will complete a battery of clinical and psychological assessments prior to treatment assignment, and again after treatment completion, to assess any changes or improvements in depression.

Trial outcomes
Primary outcomes
Change from Baseline Hamilton Depression Rating Scale (HAM-D 24) Score at 8 Weeks
Participants will have a Hamilton Depression Rating Scale-24 (HDRS) score obtained at baseline. Minimum score 0, maximum possible score 75; the higher the score on the scale, the more severe the degree of depression. After eight weeks of medication treatment, the HDRS score will be reevaluated with the HDRS-24. Participants who have a 50% or greater decrease in their HDRS-24 score will be considered responders (to treatment).
