Study on the Performance and Safety of Sentinox in COVID-19 Patients

Post-market, Confirmatory, Interventional, Randomized and Controlled Clinical Study to Assess the Efficacy and Safety of Sentinox in COVID-19 Patients.

This is a single-center, randomized, controlled, open-label, pilot study to assess the safety and the performance of Sentinox medical device in the treatment of mild COVID-19 patients.

The study will consist of 9 visits. At the screening visit, according to the investigational site procedures, patients with a positive COVID-19 nasopharyngeal swab (quantitative swab test with RT-PCR Ct value ≤ 30 for at least 2 genes out of 4) performed at the investigational site on the same day will be summoned. Patients will be enrolled after having signed the informed consent form prior to any other study procedure and after inclusion/exclusion criteria check. According to the investigator's judgment, the patient's clinical outcomes, and the investigational site guidelines, the enrolled patients should be hospitalized or redirected to other structures (e.g. "COVID-19 hotel", patient's home).

At Visit 0 (day 0), the patient will be randomized with a 1:1:1 ratio in one of 3 trial groups:

1. Group A: Sentinox treatment performed 3 times/day for 5 days (as add-on to the standard therapy);
2. Group B: Sentinox treatment performed 5 times/day for 5 days (as add-on to the standard therapy);
3. Group C: no Sentinox treatment; only the standard therapy will be performed.

The allocation of the patient in one of the three study arms will be performed sequentially by the principal investigator or delegates in the order in which the subjects are enrolled and will be reported in a randomization list, including the identification code of the patient and the treatment arm (A, B or C) assigned.

At Visit 1 (day 1) and Visit 2 (day 2), three nasopharyngeal swabs will be performed. At subsequent planned visits only one nasopharyngeal swab will be performed in the morning. From Visit 1 (day 1) to Visit 5 (day 5), patients will record daily adverse events (AE), concomitant medication, and presence of clinical features COVID-19 related in a diary.

After the end of the treatment visit (Visit 5), three follow-up visits will be performed on day 6, day 10, and day 21 respectively.

In the study COVID-19 patient with RT-PCR Ct value ≤ 30 for at least 2 genes out of 4, at the first swab will be enrolled. The enrollment of COVID-19 vaccinated patients will be allowed if they will present a "clinical vaccination failure", defined according to the indications reported in the "Global Manual on Surveillance of AE Following Immunization" (WHO guidelines).
• Onset of symptoms from not more than 2/3 days

Exclusion Criteria:

• Other clinically significant and uncontrolled pathologies that may interfere with study results (e.g. rheumatic diseases);
• Presence of any relevant organic, systemic or metabolic disease (particularly significant history of cardiac, renal, neurological, psychiatric, oncology, endocrinology, metabolic or hepatic disease), or abnormal laboratory values that will be deemed clinically significant based on predefined values;
• Immune system illnesses;
• Known drug and/or alcohol abuse;
• Individuals who are cognitively impaired and/or who are unable to give informed consent;
• Ongoing or prior participation in any other clinical trial of an experimental treatment for COVID-19;
• Ongoing or prior participation in any other clinical trial of an experimental treatment within 30 days from enrollment day;
• Intubated or prior intubation (during present hospitalization) or anticipated intubation within the subsequent 2 hours;
• Using high-flow nasal cannula (HFNC) or non-invasive ventilation (NIV);
• Concurrent or planned treatment with other agents with actual or possible direct antiviral activity;
• Prior hospitalization for COVID-19;
• Positive pregnancy test or breastfeeding woman;*
• Known hypersensitivity to the study treatment, its metabolites, or formulation excipient;
• History of severe drug and / or food allergies and / or known allergies to the trial product or its components;
• Any condition that, in the opinion of the Investigator, would complicate or compromise the study or well-being of the patient.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Group A: Sentinox treatment performed 3 times/day for 5 days (as add-on to the standard therapy)	Device: Sentinox--Group A; GROUP A: Sentinox treatment performed 3 times/day for 5 days (as addon to the standard therapy) at 8am, 2pm and 8pm; The application of IP on should be performed in accordance to the following indication: The treatment is administered in a dose of 0.5 ml into each nostril (5 sprays) per the number of times per day according the trial group assigned according the randomization procedure (i.e., GROUP A: 3 times/day; GROUP B: 5 times/day; GROUP C: no IP treatment).
Experimental: Group B: Sentinox treatment performed 5 times/day for 5 days (as add-on to the standard therapy)	Device: Sentinox--Group B; GROUP B: Sentinox treatment performed 5 times/day for 5 days (as addon to the standard therapy) at 8am, 11am, 2pm, 5pm and 8pm; The application of IP on should be performed in accordance to the following indication: The treatment is administered in a dose of 0.5 ml into each nostril (5 sprays) per the number of times per day according the trial group assigned according the randomization procedure (i.e., GROUP A: 3 times/day; GROUP B: 5 times/day; GROUP C: no IP treatment).
