RENOVATE: High-Flow Nasal Oxygen Cannula Compared to Non-Invasive Ventilation in Adult Patients With AcuTE Respiratory Failure
Study Details
Study Description
Brief Summary
RENOVATE study aims to investigate if the respiratory support device called High-Flow Nasal Oxygen Cannula (HFNC) acts similarly (non-inferior) to another respiratory support device called Non-Invasive positive-pressure Ventilation (NIPPV) in preventing endotracheal intubation in adult patients with Acute Respiratory Failure (ARF) from different causes. HFNC is a somewhat new method of respiratory support in adults that has been used in neonatal ARF for some years. The reason this study is necessary is that, even though NIPPV has been demonstrated to prevent endotracheal intubation (and its associated complications) in a broad range of ARF patients, HFNC has been proposed to have the same beneficial effect of NIPPV while being easier tolerated, allowing patients to talk, eat and drink through mouth while on HFNC. RENOVATE will recruit between 800 to 2000 patients (adaptive design) with different types of ARF in Brazil. Patients will be randomized to HFNC or NIPPV and the rate of endotracheal intubation will be compared between groups as well as other parameters such as vital status and other health care related complications.
[IMPORTANT NOTE] On April 13, 2021, on the first interim analysis, the DSMB recommended the interruption of the immunocompromised hypoxemic ARF subgroup.

Detailed Description
RENOVATE will investigate if High-Flow Nasal Oxygen Cannula (HFNC) is non-inferior to Non-Invasive positive-pressure Ventilation (NIPPV) in preventing endotracheal intubation or death in adult patients with Acute Respiratory Failure (ARF) from different causes in 7 days. HFNC is a somewhat new method of respiratory support in adults that has been used in neonatal ARF for some years. Even though NIPPV has been demonstrated to prevent endotracheal intubation (and its associated complications) in a broad range of ARF patients, HFNC may have beneficial effect over NIPPV because it is easier to be tolerated, allowing patients to talk, eat and drink through mouth while on therapy. RENOVATE will recruit between 800 to 2000 patients (adaptive design) with different types of ARF in Brazil. The main hypothesis is that HFNC is non inferior to NIPPV in reducing intubation rate or death within 7 days. However, as an adaptive study, this non inferiority hypothesis may change to superiority if gathered data during the study is promissing in the interim analysis. Therefore, sample size may increase to 2000 participants. Patients will be randomized to HFNC or NIPPV and the rate of endotracheal intubation will be compared between groups as well as other parameters such as vital status and other health care related complications.
[IMPORTANT NOTE] On April 13, 2021, on the first interim analysis, the DSMB recommended the interruption of the immunocompromised hypoxemic ARF subgroup.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: High Flow Nasal Catheter The HFNC (AIRVO2 Fisher & Paykel, Auckland, New Zealand) consists of an apparatus that allows adjustable FiO2 from 21 to 100% and delivers flow up to 60 L/ min. |
Device: High Flow Nasal Catheter
HFNC will deliver through AIRVO2. FiO2 from 21 to 100% and heated humidified gas flow up to 60 l / min with temperature of the circuit maintained at 37 degrees.
Oxygen flow will be offered through a humidified nasal catheter. Flow and FiO2 will be titrated according to the protocol to maximize patient´s comfort and SpO2.
Other Names:
|
| Active Comparator: Non-invasive positive pressure ventilation NIPPV will be performed using the devices available on centers. Both a dedicated NIPPV device or invasive mechanical ventilator with NIPPV mode are accepted. The interface should be a oronasal or full face mask. |
Device: Noninvasive ventilation
NIPPV will be performed using a facial mask (either oronasal or full face). NIPPV will deliver pressures and FiO2 tailored to specific ARF subgroups, according to the protocol. Adjustments of the inspiratory pressure (IPAP) and expiratory pressure (EPAP) and FiO2 according to protocol
