A Phase I Study of the EmitBio™ RD19 Device to Prevent SARS-CoV-2 and COVID-19

Respiratory Tract Infections Clinical Trial

Official title: A Phase I Open Label, First-in-Man Acute Safety, Tolerability and Acceptability Study of the EmitBio™ RD19 Device to Prevent SARS-CoV-2 Infection and COVID-19 Disease

Status Not yet recruiting

Clinical Trial Summary

This first-in-man (FIM) phase I study will evaluate the acute safety, tolerability, and device acceptability for use among 25 healthy volunteers between the age of 18 and 45.

Safety and tolerability (local reactogenicity) will be assessed actively at screening (baseline set), and study days 1, 7 and 14, and on non-clinic visit days by collection of these data by history during clinic visits via a memory aid (diary cards).

Metabolic, liver and kidney safety laboratory evaluations, as well as urinalysis, will be performed at screening and at Day 14 or early termination (and potentially during unscheduled) clinic visits. Hematological safety assessments will be performed at all visits.

Clinical Trial Description

This first-in-man (FIM) phase I study will evaluate the acute safety, tolerability, and device acceptability for use among 25 healthy volunteers between the age of 18 and 45. Based on the results of numerous preclinical studies, a single dose (5 joules/cm2) and schedule (twice a day, separated by at least 4 hours, preferably 8 to 12 hours apart) will be evaluated.

Safety and tolerability (local reactogenicity) will be assessed actively at the following study days: screening (baseline set), 1, 7 and 14, and on non-clinic visit days by collection of these data by history during clinic visits via a memory aid (diary cards). Volunteers will be encouraged to promptly contact designated clinical trial staff or the one of the Sponsor's Emergency Response Team for AEs of a medically urgent nature.

A Comprehensive Metabolic Panel, as well as CBC with differential, urinalysis, and pregnancy testing will be performed at screening and at Day 14 or early termination (and potentially during unscheduled) clinic visits. Hematological safety assessments (evaluation of methemoglobinemia) will be performed at all visits.

Study volunteers will be asked to immediately contact the clinical coordinator and/or the PI in all instances where they experience an AE of greater than moderate intensity. Volunteers will be instructed to report to the clinical trial unit for an unscheduled visit or to seek the appropriate level of medical care based on the nature of their AE/SAE. In all such instances, all relevant information pertaining to these significant medical events will be captured on the appropriate e-CRFs.

Hematology safety laboratory evaluations will be performed at screening, as well during all scheduled clinic visits. Laboratory assessments may be part of the evaluation of medically attended AE evaluation and for all SAEs.

Upon ratification of the CTA, the site will begin pre-recruitment outreach efforts of potential volunteers within M3-WRA's database to ascertain "interest in general" in this study. Official recruitment which may include fliers, letters, telephone calls, etc. and specific recruitment of potential subjects who have previously participated in other clinical studies conducted at the site will occur only after formal IRB approval. Other forms and/or mechanisms of recruitment may also be used. The IRB will approve the recruitment process and all materials prior to use.

Schedule of assessments can be found in Section 1.2, Schedule of Activities (Table 3).

3.2 Objectives and Outcomes OBJECTIVES ENDPOINTS (OUTCOME MEASURES) Primary

• Evaluation of the acute safety of the EmitBio™ RD19 device. • Frequency, grade and attribution of each incident local and systemic AE during the 14day study period.

• Frequency and attribution of any incident SAEs during the 14 \day study period. Secondary

• Evaluation of the acceptability of the EmitBio™ RD19 device. • Ease of use, clarity of user instructions, & compliance with per protocol schedule and, if out of compliance, reason(s) for noncompliance.

3.3 Scientific Rationale for Study Design The EmitBio™ RD19 device is designed to place a protective countermeasure in the hands of at population-risk individuals in order to reduce the incidence of SARS-CoV-2 and COVID-19. At population-risk individuals are those living where community-transmission of SARS-CoV-2 is likely to occur and where community transmission is actively occurring. Through the identified mechanisms of virus killing and inhibition of virus replication, the RD19 device is expected to reduce SARS-CoV-2 viral load which in combination with other lifestyle measures, may help reduce the incidence of SARS-CoV-2 infection. This type of active protection is urgently needed for high-risk individuals (e.g. individuals exposed to a known infected person and healthcare workers and eldercare facility staff exposed to SARS-CoV-2 infected / COVID-19 patients and residents, respectively). The RD19 device has been engineered with the intent to help curb community transmission of SARS-CoV-2, thereby reducing the incidence of COVID-19. The CDC estimates that 40% of secondary coronavirus transmission occurs before people feel ill, highlighting the need for a broadly distributed protective countermeasure.

The RD19 optical illumination device is inserted into the mouth to shine light on the proximal repository for respiratory tract pathogens in the pharynx. The RD19 device uses a precise color of visible blue light (absent of UV light) to stimulate host defense and eliminate invading pathogens. This color of blue light has been found to both stimulate the instantaneous release of the body's reserves of nitric oxide and to increase endogenous production of nitric oxide in barrier epithelial cells. This naturally produced nitric oxide is substantially elevated over background levels and promotes innate immune responses capable of disrupting SARS-CoV-2 infection and inhibit viral replication of human coronaviruses. In addition to its direct antiviral activity, nitric oxide is an important pro-inflammatory cell signal to elicit induction and recruitment of other innate immune effectors, including NK cells, neutrophils, and macrophages.

3.4 Justification for Dose In repeated experiments, including experiments conducted by third party external laboratories, it has been determined that the light emitted by the EmitBio™ RD19 device provides for potent antiviral activity against SARS-CoV-2. Reductions in viral infectivity of host cells >90% have been observed after a single illumination at an energy level of 7.5 joules/cm2. Separately, the yield of replicating SARS-CoV-2 virus in infected cells is inhibited by 50% at range of 9 - 15 J/cm2. Dosing twice a day (total of 15 J/cm2) also allows endogenous nitric oxide levels to be elevated to an extent and for a time period expected to result in high level antiviral effects.

4. STUDY POPULATION Twenty-five (25) males and non-pregnant females, 18 to 45 years of age inclusive, who are in good health and meet all eligibility criteria will be enrolled. The target population should reflect the community at large. The estimated time from initiation of enrollment to completion of the day 1 visit for the last subject enrolled is one week.

Subject Inclusion and Exclusion Criteria must be confirmed by a study clinician, licensed to make medical diagnoses and signatory to The Statement of Compliance as the site PI. Exemptions will be only be granted on Subject Inclusion or Exclusion in rare instances and based on the approval of the Sponsor's Chief Medical Officer. ;
