MEGA-ROX: BUILDING PATIENT-CENTRIC RESEARCH
CAPACITY FOR BETTER CARE IN OXYGEN THERAPY
THE MEGA-ROX TRIAL
The Mega-ROX trial is a multicentre, multinational, randomized clinical trial to compare conservative oxygen therapy with usual oxygen therapy in mechanically ventilated patients who are either non-electively admitted to the ICU or intubated in the ICU.
MILESTONES
Trial Update: The Mega-ROX trial has now hit 25,000 enrolments worldwide with only 15,000 more to go.
REPORT
Primary Outcome: To determine that a conservative approach to oxygen therapy will reduce mortality compared to a liberal approach.
CASE STUDY
“This trial is about so much more than just numbers – it's about redefining what's possible in healthcare and making a lasting impact on patients' lives.”
DIANE MACKLE, PROJECT MANAGER, MEGA-ROX TRIAL
BACKGROUND
Provision of life support (mechanical ventilation) is required for most critically ill patients who are admitted to an intensive care unit (ICU). Delivery of supplemental oxygen to ICU patients who require mechanical ventilation often exposes them to a high fraction of inspired oxygen (FIO2) and higher than normal arterial oxygen partial pressure (PaO2).
The ICU-ROX trial findings did not exclude clinically important effects of the oxygen regimens tested on mortality.
Patients with acute hypoxemic respiratory failure in the intensive care unit (ICU) are treated with supplemental oxygen, but the benefits and harms of different oxygenation targets are unclear. It was hypothesized that using a lower target for partial pressure of arterial oxygen (Pao2) would result in lower mortality than using a higher target.
TRIAL DESIGN
Mega-ROX is a series of multicentre, multinational, randomised, parallel-group, registry-embedded clinical trials nested within an overall 40,000-patient trial sample.
This 40,000 participant trial will be conducted in multiple countries and includes innovative trial design features:
Linkage to identify enrolled patients in national ICU registries so that outcome data do not need to be collected specifically for the trial;
Response adaptive randomisation giving trial participants an increased chance of being assigned to the oxygen regimen associated with the lowest mortality risk while the trial is ongoing (based on accumulated data within individual subgroups).
Due to updates in Spiral’s Spinnaker platform, Mega-ROX has been translated into Portuguese, allowing for the first Brazilian patient to be enrolled in 2022.
