COVIDNOCHE Trial (HFNO Versus CPAP Helmet) in COVID-19 Pneumonia (COVIDNOCHE)

March 25, 2022 updated by: Timothy Gaulton, M.D., University of Pennsylvania

High Flow Nasal Oxygen Versus Continuous Positive Airway Pressure Helmet Evaluation: A Randomized Crossover Trial in COVID-19 Pneumonia

The purpose of the COVIDNOCHE trial (HFNO versus CPAP Helmet Evaluation in COVID-19 Pneumonia) is to evaluate the comparative effectiveness of standard care non-invasive respiratory support (helmet CPAP versus HFNO) for acute hypoxemic respiratory failure from COVID-19 pneumonia on ventilator-free days (primary outcome) and other clinical outcomes measured up to 90 days.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Coronavirus disease 2019 (COVID-19) is a respiratory illness that can cause acute arterial hypoxemia. Treatment with invasive ventilation improves oxygenation yet results in death in over 50% of cases. The high incidence of disease has also reduced resources needed to safely deliver invasive ventilation including mechanical ventilators and intravenous sedation. Non-invasive respiratory support has been shown to be efficacious in acute hypoxemic respiratory failure from other etiologies and has the potential to reduce rates of intubation and the time spent on mechanical ventilation in COVID-19. However, it is unknown which type of support is the most effective, limiting the ability to improve clinical outcomes and appropriately allocate resources. To help guide clinical practice and policy, it is critical to understand the comparative effectiveness of two forms of non-invasive respiratory support used worldwide, continuous positive airway pressure (CPAP) delivered via a helmet interface and high flow nasal oxygen (HFNO).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Adult patients with confirmed COVID-19 with an Sp02 < 92% on ≥ 6 liters NC admitted to a Penn Medicine advanced respiratory unit. An advanced respiratory unit is a unit capable of non-invasive respiratory support such as an ICU or intermediate care unit.

Exclusion Criteria:

Patients will be excluded if they meet ≥ 1 of the following criteria based on current Penn Medicine respiratory guidelines and prior trials of non-invasive respiratory support:

  • Respiratory failure related to other etiology (e.g. exacerbation of chronic obstructive pulmonary disease, acute pulmonary edema)
  • Baseline oxygen requirement
  • Diagnosis of acute or chronic hypoventilation
  • Tracheostomy
  • Claustrophobia
  • Prior intubation during hospitalization
  • Urgent need for endotracheal intubation
  • Other contraindications to non-invasive respiratory support (glasgow coma scale lower than 8, absence of airway protective gag reflex, elevated intracranial pressure, upper airway obstruction)
  • Patient dose not wave to receive the assigned intervention.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
ACTIVE_COMPARATOR: Helmet Continuous Positive Airway Pressure (CPAP)
When a patient has an Sp02 < 92% on ≥ 6 LPM NC, helmet CPAP will be applied unless a specific contraindication is present.
Device: Helmet Continuous Positive Airway Pressure (CPAP)
Helmet CPAP will be initiated at a pressure of 5 cmH20 and fraction of inspired oxygen (Fi02) of < 60%. If oxygen saturation (Sp02) remains < 92%, pressure will be increased to 10 cmH20. FiO2 will then be tapered to target a SpO2 ≥ 92%. Breaks with intervening HFNO use will be provided as needed for meals and during hours of sleep.
ACTIVE_COMPARATOR: High Flow Nasal Oxygen (HFNO)
When a patient has an Sp02 < 92% on ≥ 6 LPM NC , HFNO (≥ 40 LPM) will be applied unless a specific contraindication is present
Device: High Flow Nasal Oxygen (HFNO)
HFNO will be initiated at a flow rate of 40 LPM and a fraction of inspired oxygen (Fi02) of < 60%. If oxygen saturation (SpO2) remains < 92%, the flow rate will be increased to 60 LPM. FiO2 will then be adjusted to target a SpO2 ≥ 92%. Patients with discomfort due to HFNO may have their flow rate decreased until the discomfort resolves.
Other Names:
  • High Flow Nasal Cannula (HFNC)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Ventilator-Free Days (VFD)
Time Frame: 28 days
VFD is the number of days alive and free of mechanical ventilation in the first 28 days after study enrollment. Death before 28 days will be assigned a VFD equal to 0 to penalize non-survival. In cases of repeated intubation and extubation, periods free from invasive ventilation and lasting at least 24 consecutive hours will be calculated and summed. Timing of intubation and extubation will be captured in hours, and the number of hours a patient received invasive ventilation will be used to calculate duration of ventilation.
28 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
ICU and Hospital Length of Stay
Time Frame: 28 days
Days spent in the ICU and hospital after time of enrollment
28 days
