Outcome Measures

Primary Outcomes (1)

  • SARS-CoV-2 viral titer reduction

    Change from baseline PCR count with testing on days 3, 7 and 14

    Immediately following treatment and on days 3, 7, and 14.

Secondary Outcomes (1)

  • General safety of nasal photodisinfection

    14 days post treatment

Study Arms (2)

Active Intervention

EXPERIMENTAL

The procedure is initiated by swabbing the Formulation Applicator, pre-saturated with photosensitizer formulation, inside the patient's nares. The operator then connects the Nasal Light Illuminator (NLI) to the Light Source and inserts the NLIs into the patient's nostrils. The Light Source is turned on, and a 4-minute illumination cycle provides two channels of diffused red light (one for each nostril) to activate the applied formulation. Illumination stops automatically upon completion of the 4-minute cycle. The process is then repeated using two new Formulation Applicators to ensure full disinfection coverage.

Active Intervention

Patients who are SARS-CoV-2 positive whose PCR levels are followed but no active intervention will be done. Saline will be used in their nose and the light device will be inserted but not turned on. Patient will be wearing light protecting glasses.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Provision of signed and dated informed consent form
  • Stated willingness to comply with all study procedures and availability for the duration of the study
  • Male or female ≥ 18 years of age
  • Patient showing a positive test for SARS-CoV-2 with \< 26 Ct of an FDA-approved PCR test who is symptomatic or flu-like illness or pneumonia
  • Ability to tolerate an 12-minute non-painful nasal light illumination

You may not qualify if:

  • Inability to tolerate insertion of the light illuminator due to oronasal size, shape, or anatomical variants

  • COVID-19 illness that is moderate or severe in nature.

Masking Details
The placebo control arm will include the application of saline isotonic solution and the introduction of the PDT device with no powering on. Due to the characteristics of the device, and the need for the investigator to deliberately not switching it on, it is clear that there cannot be a blind scheme in this trial.
