Eligibility criteria

Inclusion Criteria:

  • Inclusion Criteria:
  • 18 years and above.
  • COVID-19 infection Confirmed with a laboratory SARS-CoV-2 RT-PCR nasal swab or antigen test. COVID-19 test specimen must be collected 48 hours prior to Screenings.
  • Mild COVID-19 Infection defined as:

    • No Pneumonia (negative by chest auscultation or Chest X Ray).
    • No Shortness of breath.
    • No Tachypnea (respiratory rate \<20 breathes/min)
    • No Hypoxia (Oxygen saturation >93% on RA)
    • Fever \<38 degrees.
    • No Chest Pain.
    • No Mental Status Change.
  • Asymptomatic participants must be high risk defined as (any of the following):

    • Smokers (at least 5 cigarettes per day)
    • (> 40 kg/m2)
    • History of cardiac or chronic lung disease
    • Clotting predisposing conditions (hemophilia, von Willebrand's disease)
    • Sickle cell disease
    • such as , cancer , on immunosuppressant medications

Exclusion Criteria:

  • Participants diagnosed with another (non-COVID-19) respiratory infection.
  • Participants with a current tracheostomy or laryngectomy.
  • Participants who are receiving concomitant respiratory therapy such as oxygen, positive airway pressure or ventilatory support. NOTE: Positive airway pressure for obstructive sleep apnea is permitted if the treatment was established with good compliance for at least 3 months before study enrollment.
  • Participants with newly diagnosed illnesses that are not deemed stable by the participant's primary care physician), based on Investigator assessment of medical history during Screening.
  • Participants who use intranasally dosed drugs, prescriptions or over-the-counter medications such as fluticasone.
  • Participants who need hospitalization for reasons other than COVID-19 infection.
  • Participants who are unable to safely self-administer the nasal spray as directed.
  • Clinical signs indicative of moderate, severe, or critical COVID severity symptoms (requirement for supplemental oxygen, limitation of activities due to COVID-19 symptoms).
  • Females who are breastfeeding, pregnant, or attempting to become pregnant.
  • Participants who have experienced symptoms of COVID-19 for more than 7 days prior to randomization.
  • Participants who have any other condition that, in the opinion of the Investigator, would interfere with a participant's ability to adhere to the protocol (eg, participants who are mentally or neurologically disabled and who are considered not fit for their participation in the study), interfere with assessment of the product, or compromise the safety of the participant, or the quality of the data.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
