  • Agrees to the collection of saliva, nasopharyngeal, and venous blood specimens per protocol.
  • Males or females, 18 to 65 years of age, inclusive.
  • No uncontrolled disease process(es) based on patient reported medical history (chronic or acute), other than direct COVID-19 signs and symptoms.
  • No physical or mental conditions or attributes at the time of screening, which in the opinion of the PI, will prevent full adherence to, and completion of, the protocol.
  • Symptom scoring is independent from the classification of COVID-19 disease severity at baseline. Guidance to study subjects for grading of signs and symptoms will be based on definitions used for the grading of TEAEs:
  • None (Grade 0): Not present
  • Mild (Grade 1): Symptoms that are usually transient and may require only minimal or no palliative or specific therapeutic intervention and generally do not interfere with the subject's usual activities of daily living.
  • Moderate (Grade 2): Symptoms that are usually alleviated with palliative or specific therapeutic intervention. The symptoms interfere with usual activities of daily living causing discomfort but pose no significant or permanent risk of harm to the study subject.
  • Severe (Grade 3): Events interrupt usual activities of daily living, or significantly effect clinical status, or may require intensive therapeutic intervention. Severe events are usually incapacitating.

Who cannot join

  • Positive urine pregnancy test at screening or females who intend to become pregnant during the study.
  • COVID-19 signs associated with severe respiratory distress or imminent serious medical outcomes.^^

About this study

Official title: A Phase II, Randomized, Sham Controlled Dose Finding Study of the RD-X19 Treatment Device in Individuals With Mild to Moderate COVID-19

This is a randomized, sham controlled, dose finding study of the EmitBio RD-X19 device in individuals with symptomatic COVID-19 in the outpatient setting.

Read the detailed description

This is a randomized, sham controlled, dose finding study of the EmitBio RD-X19 device in individuals with symptomatic COVID-19 in the outpatient setting. Study subjects will self-administer treatment twice daily for 7 days with a one-week follow-up period at Day 14 (+/- 2 days) and will not be aware of which treatment group to which they have been randomized. Clinical outcomes will be assessed via patient reported outcomes (questionnaire and diary cards) and virologic outcomes will be assessed post baseline on Days 3, 5, 8, and 14 via biospecimen collection.

The primary goal of the study is to evaluate multiple doses of the RD-X19 treatment device and establish evidence for safety and efficacy for each of the RD-X19 doses compared to sham in SARS-CoV-2 infected individuals with outpatient COVID-19. The primary efficacy outcome is time to sustained symptom resolution. Other clinical and microbiological outcomes will also be assessed.

Safety and tolerability (local reactogenicity) will be assessed actively and study subject diary card data recorded at each clinic visit by review of potential treatment emergent adverse events (TEAEs) and targeted oral and physical examinations. Volunteers will be instructed to contact designated clinical trial staff for AEs of a medically-urgent nature as soon as is practically possible and to seek immediate medical care, if needed. Study subjects who experience progression of disease to a grade 3 severity score (e.g SpO2 ≤ 93%, or respiratory rate ≥30/ minute on room air) will be instructed to urgently seek medical care at their nearest Urgent Care or Emergency Department. Study subjects who progress to severe acute respiratory distress syndrome with substantial risk for mortality without immediate medical intervention will be referred directly by site staff to their closest hospital. All study subjects who are hospitalized will be tracked to assess time to hospital discharge or death; the time and date of these events will be captured as part of the trial data.

Metabolic, liver, kidney and hematological laboratory evaluations will be performed at baseline and at Day 14 or early termination (and potentially during unscheduled) clinic visits. Methemoglobin assessments will be performed at baseline and Day 14.

What is being measured

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

  1. Time to Sustained Resolution of COVID-19 Signs and Symptoms in All Subjects (With Mild or Moderate Disease at Baseline).

    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 reporting a persistent fever (100.5 degrees for 36 hours or more) and/or SpO2 levels <96% with any shortness of breath are considered not to have met the success criterion on that day even if all other symptoms are reported as none (0) or mild (1).
