What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

Summary

This study tested whether giving the heart medication metoprolol through a vein could help people with severe lung failure (ARDS) in the ICU. The goal was to see if it helped them breathe without a machine for more days. However, the trial was stopped early and only 14 people took part, so no clear conclusions can be drawn.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients (≥18 years and \<80 years) with a clinical diagnosis of ARDS of any aetiology (pneumonia, including SARS-CoV-2, sepsis, pancreatitis, bronchospasm and trauma) admitted to the ICU. * Orotracheal intubation (OTI) and mechanical ventilation within 72 hours prior to randomisation. * Moderate-severe ARDS (PaO2/FiO2: ≤200 mmHg under standardised conditions (PEEP≥5 cm H2O). * Heart rate ≥ 60 bpm. * Invasive systolic blood pressure ≥ 110 mmHg. Exclusion Criteria: * Prolonged hospital admission prior to randomisation (i.e. ≥7 days at the time of randomisation). * Reduced left ventricular ejection fraction (LVEF \<50%). * Life expectancy due to other processes (cancer, degenerative diseases, etc.) of less than 6 months. * Right ventricular (RV) systolic dysfunction. * Concomitant acute heart failure (cardiac index ≤2.5 L/m2 or pulmonary capillary pressure ≥15 mmHg or clinical suspicion). * Second-degree atrioventricular (AV) block, 2:1 AV block, high-grade/advanced AV block and third-degree AV block. Also significant sinus bradycardia, which would be implied by having a heart rate \>60 bpm as an inclusion criterion. * Pregnant or breastfeeding women. * Cardiogenic shock. * Persistent invasive blood pressure \<110 mmHg despite vasopressor agents. * Use of noradrenaline at concentrations greater than 0.2 µg/kg/min at the time of the randomisation. * Use of dobutamine within 48 hours before randomisation. * Concomitant pulmonary embolism. * Known severe peripheral arterial disease. * Known asthma before admission (with active bronchodilator therapy). * Active beta-blocker treatment prior to admission (i.e. within 3 months prior to admission).
