Combination Osilodrostat and Cabergoline in Cushing's Disease (COSCA-ECD)
Combination Osilodrostat and Cabergoline Versus Osilodrostat Alone in Cushing's Disease in Iraq: Assessment of Efficacy and Safety
Cushing disease remains a challenging endocrine disorder in which persistent or recurrent hypercortisolism often requires medical therapy after surgery or when surgery is not feasible. Combination medical therapy has emerged as a rational strategy to improve biochemical control through complementary mechanisms while potentially reducing treatment escape and dose-related toxicity. Cabergoline exerts pituitary D2-receptor-mediated inhibition of ACTH secretion and may provide partial cortisol control in selected patients, although treatment escape and variable durability remain important limitations. Osilodrostat is a potent 11β-hydroxylase inhibitor that produces rapid and often substantial reductions in cortisol secretion, with clinical improvement in metabolic and cardiovascular features of hypercortisolism. The osilodrostat-cabergoline combination is mechanistically attractive because it pairs central ACTH suppression with peripheral blockade of cortisol synthesis, but published evidence remains limited to small real-world experiences and does not yet define optimal sequencing, dosing, or long-term benefit. Safety considerations include adrenal insufficiency from overtreatment, osilodrostat-associated hypertension from mineralocorticoid precursor accumulation, and hyperandrogenism due to steroid precursor shunting.
Combination medical therapy in Cushing disease is a promising individualized approach, and the osilodrostat-cabergoline pairing is biologically plausible and potentially effective, but current literature is insufficient to support firm recommendations regarding efficacy, safety, or patient selection.
The study aims to evaluate whether a combination can result in rapid, more control of Cushing's disease (clinically and biochemically)? Can cabergoline reduces Osilodrostat dose requirement, reduces Osilodrostat related mineralocorticoid and hyperandrogenism side effects?
