Comparison of Viral Particle Dispersion Following Administration of an MDI or Nebulizer in Subjects With COVID-19

January 27, 2022 updated by: Theravance Biopharma

A 2-Period, Crossover Study to Assess the Impact of Nebulizer With Filtered Mouthpiece vs MDI With Spacer on Viral Load in Rooms of Subjects With Mild to Moderate COVID-19

A randomized, 2-period crossover, single-center, open-label study for viral sample collection. After initiation of inhaled therapy with nebulizer or MDI, cascade impactors and surface samplers will be used to assess viral loads in rooms of subjects with COVID-19.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Observational Study Model = Other [non-treatment; impact on external location (rooms and surfaces)]

Time Perspective = Other [viral load samples taken at various time points after nebulization or MDI administered]

Sampling Method = Non-probability sample [to be described by study team]

Study Type

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

Sampling Method

Non-Probability Sample

Study Population

Subjects with mild to moderate COVID-19

Description

Inclusion Criteria:

  1. Willing and able to provide written informed consent, either themselves or via legally acceptable representative, prior to undergoing study procedures
  2. Willing and able to comply with study-related procedures/assessments
  3. Adults over 18 years of age
  4. COVID-19 infection as confirmed by PCR from nasopharyngeal, oropharyngeal swabs and/or saliva specimen taken within the previous 5 days

Exclusion Criteria:

  1. Subjects currently receiving mechanical ventilation or noninvasive positive-pressure ventilation, or subjects who, in the opinion of the investigator, will require ventilatory support (i.e., mechanical ventilation or noninvasive positive-pressure ventilation) within the next 12 hours Note: Signs of impending need for ventilatory support include pronounced hypoxia despite supplemental oxygen >6 L/min, prolonged respiratory rate (i.e., >30 breaths per minute), signs of respiratory muscle fatigue, or paradoxical diaphragm.
  2. Presence of significant comorbidity that, in the opinion of the investigator, makes the subject unsuitable for participation in the study
  3. Known or suspected hypersensitivity to albuterol, history of paradoxical bronchospasm, or significant cough response to albuterol
  4. Participating in other clinical trials related to COVID-19 thought to interfere with study interpretation (e.g., antivirals or antibodies that might change the viral load over the course of a day; subjects should not receive antibody therapy within 24 hours before the baseline period)
  5. Active or incompletely treated pulmonary infections, such as tuberculosis (or known history of nontuberculosis mycobacterium) over past 12 months
  6. Pregnant or currently breast feeding, or a positive urine pregnancy dip test performed at baseline (women only)

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

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
Viral Load
Time Frame: Baseline, Day 1
Change in viral load from baseline at each sample point (room air and surfaces). This outcome measure is listed as exploratory in the protocol.
Baseline, Day 1

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
May 4, 2021

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
