About this study

Official title: A Randomized, Double-Blind, Sham Controlled, Stratified, Pivotal Efficacy and Safety Study of the EmitBio RD-X19 Treatment Device in Individuals 40 Years of Age and Older With Mild COVID-19 in the At-Home Setting

This is a randomized, double-blind, sham controlled, stratified, pivotal efficacy and safety study of the EmitBio RD-X19 treatment device in Individuals 40 Years of age and older with Mild COVID-19 in the at-home setting.

Read the detailed description

This is a randomized, double-blind, sham controlled, stratified, pivotal efficacy and safety study of the EmitBio RD-X19 device in individuals age 40 and older with mild COVID-19 (as defined by NIH and FDA) in the at-home setting. Study subjects will self-administer treatment twice daily, 5 minutes per treatment for 7 consecutive days. Subjects will remain on study for a total of 14 study days (± 2 days) for treatment and follow-up. Neither study subject nor clinical trial personnel will be aware of the subject's treatment assignment. Clinical safety and efficacy outcomes will be assessed via self-assessed signs and symptoms (e-diary entries twice a day during the entire study period) with daily study staff checks, including home visits, and/or clinic visits for objective clinical assessments (vital signs, targeted physical exams, oropharyngeal exams) on study days 1, 5, 8 and 14.

The primary goal of the study is to evaluate the safety and efficacy of the RD-X19 treatment device to provide sufficient evidence to FDA to justify the authorization and/or approval of the device for treatment of subjects with mild COVID-19, age 40 and older in the home setting. Every attempt will be made to continue to follow safety in any study subject choosing to terminate the study early and all study subjects who progress to moderate or more severe forms of COVID-19 will be immediately referred for appropriate medical care. Medically necessary care of study participants will always take precedence over research.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subjects With Sustained Resolution of COVID-19 Signs and Symptoms Without Subsequent Symptom Recurrence or Disease Progression (Until the End of the Study)

    Each of eight symptoms (cough, sore throat, nasal congestion, headache, chills and or sweats, myalgia, fatigue, and nausea (with or without vomiting)) will be rated on a 4-point scale from none (0) to severe (3). Time to sustained resolution of COVID-19 signs and symptoms as measured by the time (in hours) when all eight symptoms have been assessed by the subject as none (0) or mild (1) and all symptoms remain at or below 1 until study Day 14. Subjects that are hospitalized will be censored at 360 hours, which corresponds to the end of the time window for the day 14. A subject not satisfying case (i) or (ii), who takes nirmatrelvir/ritonavir or molnupiravir after initiating study treatment will be censored at the time that they first took this antiviral medication. Subjects not satisfying case (i), (ii), or (iii) will be censored at the last time that they have e-diary data recorded.

    Measured: Baseline through Day 14

  2. Kaplan-Meier Estimates for Time to Sustained Resolution of COVID-19 Signs and Symptoms Without Subsequent Symptom Recurrence or Disease Progression (Until the End of the Study) Full Analysis Set (FAS)

    Each of eight symptoms (cough, sore throat, nasal congestion, headache, chills and or sweats, myalgia, fatigue, and nausea (with or without vomiting)) will be rated on a 4-point scale from none (0) to severe (3). Time to sustained resolution of COVID-19 signs and symptoms as measured by the time (in hours) when all eight symptoms have been assessed by the subject as none (0) or mild (1) and all symptoms remain at or below 1 until study Day 14. Subjects that are hospitalized will be censored at 360 hours, which corresponds to the end of the time window for the day 14 visit. A subject not satisfying case (i) or (ii), who takes nirmatrelvir/ritonavir or molnupiravir after initiating study treatment will be censored at the time that they first took this antiviral medication. Subjects not satisfying case (i), (ii), or (iii) will be censored at the last time that they have e-diary data recorded.

    Measured: Baseline through Day 14

Secondary outcomes (2)
  1. Number of Subjects With Two Negative SARS-CoV-2 Antigen Tests (With a Minimum Time Between Tests of Six Hours) Without Subsequent Virological Rebound During the Subject's Remaining Time on Study

    Number of subjects with two negative SARS-CoV-2 antigen tests (with a minimum time between tests of six hours) without subsequent virological rebound during the subject's remaining time on study. Subjects that are hospitalized will be censored at 360 hours, which corresponds to the end of the time window for the day 14 visit. A subject not satisfying case (i) or (ii), who takes nirmatrelvir/ritonavir or molnupiravir after initiating study treatment will be censored at the time that they first took this antiviral medication. Subjects not satisfying case (i), (ii), or (iii) will be censored at the last time that they have e-diary data recorded

    Measured: Baseline through Day 14

  2. Kaplan-Meier Estimates Time to First of Two Negative SARS-CoV-2 Antigen Tests

    time to first of two negative SARS-CoV-2 antigen tests (with a minimum time between tests of six hours) without subsequent virologic rebound (during the subject's remaining time on study) Full Analysis Set (FAS)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 15 inclusion and 18 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 24 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 48 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 24 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects With Sustained Resolution of COVID-19 Signs and Symptoms Without Subsequent Symptom Recurrence or Disease Progression (Until the End of the Study) (time frame: Baseline through Day 14). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
