About

To determine whether inhaled Yabro protects against progression of COVID19-induced respiratory failure preventing the passage to non-invasive ventilation (NIV) and promotes recovery from COVID19 lung disease in hospitalized patients.

Full description

All patients will be treated with state of the art COVID19 treatment as per the treating clinician (Remdesivir, systemic corticosteroids, monoclonal antibodies, convalescent plasma, biologic cytokine inhibitors and other interventions as per the latest guidelines). Patients randomized to the active intervention group will also receive HMW-HA (Yabro®, 5 ml of saline containing 0.3% hyaluronic acid sodium salt) via nebulizer, while patients randomized in the control group will receive a matching placebo two times daily.

Due to increased risk for SARS-CoV-2 transmission via the usual mask nebulization procedure, patients will receive the nebulized treatment via high-flow oxygen tubing as described in the literature 36-38. Patients will be treated until there is a qualitative change in oxygen requirement, i.e. either progression to assisted ventilation (non-invasive or invasive), or weaning from oxygen supplementation. Because COVID19 may result in long-term O2 dependency, the study and treatment period will be limited to a maximum of 10 days.

Moreover, a blood sample (20 ml) will be taken at baseline and after 10 days of treatment.
