Study Details

Study Description

Brief Summary

This is a prospective, multicenter, randomized (3:1), placebo- controlled, parallel-group, double-blind trial.

Patients will be randomized into two arms of treatment:
  • Placebo + SoC (N=30)

  • NanoManganese® + SoC (N=90)

Patients will be treated and followed-up for 10 days:
  • Arterial oxygen partial pressure (PaO2) will be measured at baseline and at days 3, 5 and 10,

  • Oxygen saturation, vital signs including respiration rate, pulse rate, blood pressure and body temperature, disease severity (7-point ordinal scale and NEWS2 score) will be measured at baseline and daily,

  • Hematology and biochemistry measurements will be done at baseline and at day 3, 5 and 10,

  • Pharmacokinetic (Blood Mn concentration) measurements will be done at baseline and at day 3, 5 and 10,

  • Biomarkers will be measured at baseline and at day 3, 5 and 10. At the end of the 10-day treatment period, a follow-up visit will be planned between day 15 and day 22. The following.

assessments/examinations will be performed: oxygen saturation, vital signs including respiration rate and body temperature, disease severity (7-point ordinal scale and NEWS2 score), electrocardiogram (ECG), hematology, biochemistry, concomitant therapies, and adverse events.

Condition or Disease Intervention/Treatment Phase
  • Drug: Placebo
  • Drug: Experimental drug
Phase 1/Phase 2

Detailed Description

120 patients will be enrolled in this study, they will be randomly assigned in 2 arms on a 3:1 ratio, 90 patients in the NanoManganese®

  • Standard of Care group and 30 patients in the placebo + Standard of Care group.

This study will be conducted in Brazil and will be conducted in around 8 investigational sites

The investigational products are :

Manganese sulfate monohydrate, MnSO4, H2O (NanoManganese®) will be administered using the microemulsion AONYS® technology. The product is mucoadhesive, it sticks to the mucosa of the cheeks on which it will be deposited and will not be swallowed.

The placebo (Pharmacopoeia soybean oil) will be administered using the same protocol and the same bottle.

Treatments :
NanoManganese® + standard of care group:
  • NanoManganese®: administration of 2 mL twice a day (morning and evening) by depositing 1 mL in the gingivo-jugal groove of each cheek with the graduated pipette.

  • Standard of care

Placebo + standard of care group:
  • Placebo: administration of 2 mL twice a day (morning and evening) by depositing 1 mL in the gingivo-jugal groove of each cheek with the graduated pipette.

  • Standard of care The treatments will be administered by the nurse. Duration of treatment: 10 days or until hospital discharge or until death.

Drug: Experimental drug
The administration of the treatment consists in a deposit in the gingivo-jugal groove of each cheek with a graduated pipette

Outcome Measures

Primary Outcome Measures

  1. Change of the PaO2/FiO2 ratio [10 days]

    Change from baseline to D10 of the PaO2/FiO2 ratio in the NanoManganese® + SoC group and in the placebo+ SoC group.

Secondary Outcome Measures

  1. Proportion of patients with PaO2 > 65 mmHg [10 days]

    Proportion of patients with PaO2 > 65 mmHg at D3, at D5 and at D10, measured preferable after IP administration in the morning.

  2. Change of PaO2 [10 days]

    Change between baseline and D10 of PaO2

  3. Evolution of respiratory rate over time [10 days]

    Evolution of respiratory rate over time

  4. Proportion of patients with SpO2 ≥ 95% [10 days]

    Proportion of patients with SpO2 ≥ 95% at D3, D5 and at D10,

  5. Change of SpO2 [10 days]

    Change between baseline and D10 of SpO2,

  6. Incidence of oxygen use [10 days]

  7. Duration of oxygen use [10 days]

  8. Oxygen free days at D15-22 after inclusion [10 days]
