Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Randomised, double-blind, placebo-controlled clinical trial to evaluate the efficacy of intravenous metoprolol in patients with Acute Respiratory Respiratory Distress Syndrome (ARDS).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a placebo-controlled, randomised, double-blind, multicentre, Phase III clinical trial to assess the efficacy of IV metoprolol in newly intubated ARDS patients, assessing survival and days free of invasive mechanical ventilation during the first 28 days. Eligible participants shall have had 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), a heart rate ≥ 60 bpm and invasive systolic blood pressure ≥ 110 mmHg.The trial will include a total of n=350 patients, with two treatment arms: metoprolol vs. placebo (1:1). Each of the 7 days of treatment, participants will be receive 15 mg of iv metoprolol tartrate or matching placebo in 100 ml of saline for 10 minutes.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Randomization (1:1) will be stratified according to the severity of ARDS and by participating centre:

* Moderate (PaO2/FiO2 of 100-200 mmHg).
* Severe (PaO2/FiO2 ≤100 mmHg).

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
Both metoprolol and saline are supplied in 5 ml ampoules of the same shape, structure and colour

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Metoprolol

Participants will be administered IV Metoprolol tartrate 15 mg (3 ampoules of 5 ml) diluted in 100 ml of saline.

Group Type ACTIVE_COMPARATOR

Metoprolol Injection

Intervention Type DRUG

A dilution of 15 mg Metoprolol tartrate in 100 ml saline shall be performed and infused for 10 minutes. No dose reduction or increase is allowed. Systolic blood pressure and heart rate shall be measured 3 and 6 minutes after starting the infusion.

In case of a consistent drop in systolic blood pressure or heart rate, the infusion shall be stopped and the infusion noted.

Saline

Participants will be administered IV saline (0.9% sodium chloride) (3 ampoules of 5 ml) diluted in 100 ml of saline.

Group Type PLACEBO_COMPARATOR

saline 0.9%

Intervention Type DRUG

A dilution of 0.9% sodium chloride in 100 ml saline shall be performed and infused for 10 minutes. No dose reduction or increase is allowed. Systolic blood pressure and heart rate shall be measured 3 and 6 minutes after starting the infusion.

In case of a consistent drop in systolic blood pressure below 110 mmHg or heart rate below 60 bpm, the infusion shall be stopped and the infusion noted.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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).
