placebo + glucocorticoids

This is a combination regimen used in clinical trials, consisting of a placebo (an inert substance with no therapeutic effect) administered alongside glucocorticoids. Glucocorticoids are a class of corticosteroid hormones that act as potent anti-inflammatory and immunosuppressive agents by binding to the glucocorticoid receptor, thereby modulating gene expression and suppressing pro-inflammatory pathways. This combination is typically used as a control or comparator arm in randomized controlled trials to assess the efficacy and safety of investigational drugs when added to standard-of-care glucocorticoid therapy. Glucocorticoids are widely used for conditions such as autoimmune diseases, allergies, asthma, adrenal insufficiency, certain cancers, and post-transplant immunosuppression[6][8][9]. The specific mechanism involves inhibition of pro-inflammatory cytokine production and immune cell activation.
