Official title: Comparing Hydrocortisone and Prednisolone for Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD)

Run by Copenhagen Respiratory Research · NCT06892210 · Data updated 2026-11-12

This test compares hydrocortisone and prednisolone to see which works better and causes fewer side effects in people 40 and older who have a COPD exacerbation.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 40 or older with diagnosed COPD presenting with an acute exacerbation who do not have contraindications to systemic corticosteroids.

Probably not a fit

Patients who require a particular corticosteroid for another diagnosis, who are pregnant or breastfeeding, or who have active tuberculosis or invasive fungal infection are unlikely to benefit from or be eligible for this comparison.

What this trial studies

This is a cluster-randomized trial that assigns participating hospitals or units to treat patients with either hydrocortisone or prednisolone for acute COPD exacerbations. Adults aged 40 and older presenting with an acute exacerbation of COPD are enrolled and receive the assigned systemic corticosteroid according to local protocols. The primary outcome is readmission for COPD exacerbation or all-cause mortality within 30 days, and safety outcomes include treatment-related side effects. Key exclusions include conditions that require a specific corticosteroid, pregnancy or breastfeeding, and active tuberculosis or invasive fungal infection.

Why it matters

Potential benefit: If successful, the trial could identify which corticosteroid reduces 30-day readmissions and deaths or has a better side-effect profile for COPD exacerbations.

How similar studies have gone: Systemic corticosteroids are known to improve outcomes in COPD exacerbations, but direct head-to-head comparisons between hydrocortisone and prednisolone are limited, so this specific comparison is relatively novel.
