Brief Summary:
Patients with documented COVID-19 infection will be randomized 1:1 to receive Piclidenoson 2 mg Q12H orally with standard care (intervention arm) or standard care alone (control arm).

Condition or disease Intervention/treatment Phase
COVID-19 Coronavirus Infection Drug: Piclidenoson Phase 2

Detailed Description:
Upon admission to the hospital, patients with documented COVID-19 infection will be randomized 1:1 to receive Piclidenoson 2 mg Q12H orally with standard care (intervention arm) or standard care alone (control arm). Piclidenoson will be administered on an empty stomach, i.e, 1 hour before or 2 hours after eating. Patients' vital signs (temperature, blood pressure, pulse rate per minute, breath rate per minute and oxygen saturation), will be monitored according to standard of care (SoC). Symptom questionnaires will be collected from patients once daily during the period of hospitalization. Efficacy of Piclidenoson will be assessed by analysis of COVID-19 (Fluxergy, Irvine CA), in respiratory secretions obtained by nasopharyngeal and oropharyngeal swabs, collected consecutively at day 1, 3, 5, 7, 10, 14, 21 and 28 following initial diagnosis, in addition to its effect on different clinical outcomes. Safety and tolerability of Piclidenoson will be assessed by AE monitoring, vital signs and ECG assessment and clinical laboratory tests (CBC, and extended chemistry panel).

    Ratio of arterial oxygen partial pressure to fractional inspired oxygen

  4. All-cause mortality [ Time Frame: 28 days ]
    Proportion of patients who die

  5. Patients reaching undetectable COVID-19 virus levels in respiratory secretions [ Time Frame: 28 days ]
    Proportion of patients reaching undetectable COVID-19 virus levels in respiratory secretions at selected timepoints

  6. Duration of symptoms and signs of respiratory infection in days [ Time Frame: 28 days ]
    Duration of symptoms and signs of respiratory infection associated with COVID-19

  7. Need for supportive respiratory management [ Time Frame: 28 days ]
    Proportion of patients who need for supportive respiratory management

  8. Viral load [ Time Frame: 28 days ]
    COVID-19 viral load in respiratory secretions using a semi-quantitative method

  9. Treatment-emergent serious AEs (SAEs) [ Time Frame: 28 days ]
    Proportion of patients experiencing AEs

  10. AEs leading to withdrawal [ Time Frame: 28 days ]
    Rate of AEs leading to early discontinuation of trial treatment

  11. Treatment-emergent abnormalities in clinical laboratory parameters [ Time Frame: 28 days ]
    Proportion of patients experiencing treatment-emergent changes in clinical laboratory
