Hydrocortisone for COVID-19 and Severe Hypoxia

Study Overview
=================
Brief Summary
-----------------
We aim to assess the benefits and harms of low-dose hydrocortisone in patients with COVID-19 and severe hypoxia.

Detailed Description
-----------------
Background: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has caused a pandemic of coronavirus disease (COVID-19) with many patients developing severe hypoxic respiratory failure. Many patients have died, and healthcare systems in several countries have been or will be overwhelmed because of a surge of patients needing hospitalisation and intensive care. There is no proven treatment for COVID-19; the care is supportive, including respiratory and circulatory support. For other patient groups with similar critical illness (acute respiratory disease syndrome and septic shock), corticosteroids are used because they reduce the duration of mechanical ventilation, length of stay in the intensive care unit, and potentially also mortality. Corticosteroids have been used in some patients with COVID-19, but the recommendations in clinical guidelines differ; some suggest their use, others against. Objectives: We aim to assess the effects of low-dose intravenous hydrocortisone on the number of days alive without life-support in adult patients with COVID-19 and severe hypoxia. Design: Multicentre, parallel-group, centrally randomised, stratified, blinded, clinical trial. Population: Adult patients with documented COVID-19 receiving at least 10 L/min of oxygen independent of delivery system OR mechanical ventilation. Experimental intervention: Continuous IV infusion of hydrocortisone 200 mg daily will be given for 7 days in addition to standard care. Control intervention: Continuous IV infusion of matching placebo (0.9% saline) will be given in addition to standard care (no corticosteroids). Outcomes: The primary outcome is days alive without life support (i.e. mechanical ventilation, circulatory support, or renal replacement therapy) at day 28. Secondary outcomes are serious adverse reactions (i.e. anaphylactic reaction to hydrocortisone, new episode of septic shock, invasive fungal infection or clinically important gastrointestinal bleeding); days alive without life support at day 90; days alive and out of hospital at day 90; all-cause mortality at day 28, day 90 and 1 year; and health-related quality of life at 1 year. Sample size: A total of 1000 participants will be randomised in order to detect a 15% relative reduction in 28-day mortality combined with a 10% reduction in time on life support among the survivors with a power of 85%.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Hydrocortisone<br>Continuous intravenous infusion of hydrocortisone 200 mg over 24 hours (total 104 ml). The trial intervention will be given in addition to standard care. If continuous intravenous infusion is not possible, we will allow the use of bolus injection of the trial medication (50 mg (10 ml) every 6 hours). | Drug: Hydrocortisone<br>* Continuous infusion: 200 mg (104 ml) every 24 hours, Bolus injections: 50 mg (10 ml) every 6 hours, Total treatment duration: 7 days<br>* Other names: Solu-cortef;|
| Placebo Comparator: Isotonic Saline<br>Continuous intravenous infusion of matching isotonic saline (0.9%) placebo at a dose volume of 104 ml over 24 hours in addition to standard care (no corticosteroid treatment). If continuous intravenous infusion is not possible, we will allow the use of bolus injection of matching saline placebo (10 ml every 6 hours). | Drug: Sodium Chloride 9mg/mL<br>* Continuous infusion: 104 ml every 24 hours, Bolus injections: 10 ml every 6 hours, Total treatment duration: 7 days<br>* Other names: Isotonic saline;|
