About

This is a multi-center, randomized, controlled, phase II clinical efficacy study evaluating a novel Nitric Oxide Releasing Solution (NORS) treatment for the prevention and treatment of COVID-19 in healthcare workers at risk of infection. Participants will be enrolled into one of two components of this study. Based on initial swabs/symptoms, volunteers who are COVID-19 negative will be enrolled in the Prevention study and randomized to receive standard institutional precautions or standard institutional precautions + NORS. Those who are COVID-19 positive will be enrolled in the open-label Treatment Sub-Study.

Full description

The novel, human-infecting corona-virus, provisionally named 2019 novel corona virus (2019-nCoV) is a single-strand, positive-sense RNA virus and has a similar receptor-binding domain structure to that of SARS-CoV and MERS-CoV. The virus is transmitted via airborne droplets to the nasal mucosa. Replication occurs locally in the nasal mucosa, in ciliated epithelial cells, over a 3-day incubation period. The mucosal cells are damaged with a resultant inflammatory response similar to the common cold. During this time the virus is shed in nasal secretions causing disease in the lower respiratory tract, potentially causing fatal viral pneumonia.

The literature supports that NO or its derivatives have inhibitory effects on a variety of viral infections. This inhibitory effect was shown to be marked in Interferon (IFN) mediated inhibition manifested by activated macrophage. It was also shown to be correlated with s-nitrosylation of viral proteins such as reductases and proteases.

Based on the genetic similarities between SARS and corona viruses, similar viricidal effects of NO on COVID-19 can be hypothesized.

SaNOtize has developed an innovative approach to provide nitric oxide gas using a formulation called Nitric Oxide Releasing Solution (NORS). This patented solution releases virucidal doses of NO for a sustained period and is effective at rapidly inactivating Influenza A and SARS-CoV-2.

NORS delivered as a gargle (AM), nasal spray (PRN) or as a nasopharyngeal flush (PM) has the potential to decontaminate the upper respiratory tract that could preventing transmission and progression of COVID-19 in Healthcare Workers & Individuals at Risk of Infection.

The randomized Prevention study will investigate the ability of NORS to prevent COVID-19 infection when used prophylactically. The open-label Treatment Sub-Study is expected to be small and will provide pilot data on the possibility of NORS as a treatment for Mild/Moderate COVID-19 infection.

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

143 participants in 3 patient groups

Prevention - Standard Precautions

No Intervention group

Description:

Participants COVID-19 negative at baseline will be randomized to receive standard COVID-19 screening and protection (per their facility or organization's protocols).

Prevention - NORS + Standard Precautions

Experimental group

Description:

Participants COVID-19 negative at baseline will be randomized to receive standard COVID-19 screening and protection (per their facility or organization's protocols) plus daily NORS treatment for 14 days.

Treatment:

Drug: NORS (Nitric Oxide Releasing Solution)

Drug: NORS (Nitric Oxide Releasing Solution)

Treatment Sub-Study

Other group

Description:

Volunteers who are found to be COVID-19 positive during screening will be eligible to enroll in the 21-day Treatment sub-study and receive daily NORS treatment for 14 days. Ten participants can be directly enrolled in the Treatment sub-study. Participants enrolled in the Prevention study who meet the criteria in this section will roll over into the Treatment Sub-Study but must remain in their randomly assigned group.
