A Multi-centre, Randomised, Double-blinded, Placebo Controlled 16-weeks Study to Compare the Effect of Hydrocortisone and Placebo in Patients With Giant Cell Arteritis (GCA)/ Polymyalgia Rheumatica (PMR) With Patient-reported Symptoms of Adrenal Insufficiency After Cessation of Glucocorticoid Treatment.

PHASE4 · Odense University Hospital · NCT05193396

What this trial studies

This clinical trial investigates the effects of hydrocortisone compared to a placebo in patients experiencing symptoms of adrenal insufficiency after discontinuing glucocorticoid treatment. The study focuses on individuals aged 50 and older who have been in remission from polymyalgia rheumatica or giant cell arteritis for a specified period after glucocorticoid therapy. The aim is to assess the incidence of glucocorticoid-induced adrenal insufficiency and determine the efficacy of hydrocortisone in alleviating symptoms. Participants will be monitored for their response to treatment over the course of the trial.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 50 and older with a diagnosis of polymyalgia rheumatica or giant cell arteritis who are in glucocorticoid-free remission.

Not a fit: Patients with known primary or secondary adrenal insufficiency or other significant health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this trial could provide a new treatment option for patients suffering from adrenal insufficiency symptoms after glucocorticoid cessation.

How similar studies have performed: Other studies have explored glucocorticoid-induced adrenal insufficiency, but this specific approach to treatment with hydrocortisone is relatively novel.
