Brief Summary:

The study is a prospective, randomized, placebo-controlled, single-blind phase 2 clinical study of the efficacy and safety of AMY-101, a potent C3 inhibitor, for the management of patients with ARDS caused by SARS-CoV-2 infection.

We will assess the efficacy and safety, as well as pharmacokinetics (PK), and pharmacodynamics (PD). The study will assess the impact of AMY-101 in patients with severe COVID19; specifically, it will assess the impact of AMY-101 1) on survival without ARDS and without oxygen requirement at day 21 and 2) on the clinical status of the patients at day 21.

Primary Outcome Measures :
  1. The proportion of patients who are alive, without evidence of ARDS (i.e. PaO2/FIO2 >300 mm Hg), who do not require any oxygen support (in room air). [ Time Frame: 21 days ]
  2. The proportion of patients assigned to each category, of a six-category ordinal scale. [ Time Frame: 21 days ]

    The clinical status is based on the following six-category ordinal scale:

    • 1: not hospitalised;
    • 2: hospitalised, not requiring supplemental oxygen;
    • 3: hospitalised, requiring supplemental oxygen;
    • 4: hospitalised, requiring nasal high-flow oxygen therapy, non-invasive mechanical ventilation, or both;
    • 5: hospitalised, requiring ECMO, invasive mechanical ventilation, or both; and
    • 6: death.


Secondary Outcome Measures :
  1. The proportion of patients assigned to each category, of a six-category ordinal scale. [ Time Frame: On days 7, 14, and 44 ]

    The clinical status is based on the following six-category ordinal scale:

    • 1: not hospitalised;
    • 2: hospitalised, not requiring supplemental oxygen;
    • 3: hospitalised, requiring supplemental oxygen;
    • 4: hospitalised, requiring nasal high-flow oxygen therapy, non-invasive mechanical ventilation, or both;
    • 5: hospitalised, requiring ECMO, invasive mechanical ventilation, or both; and
    • 6: death.

  2. Proportion of patients surviving [ Time Frame: Through to day 44 ]
  3. Proportion of respiratory failure-free survival [ Time Frame: Day 44 ]

    With respiratory failure defined as any of the following:

    1. Worsening of severe gas transfer deficit, accounting for a shift in ARDS disease category (PaO2/FiO2 ≤200 for patients with PaO2/FiO2 >200 at baseline; PaO2/FiO2 ≤100 for patients with PaO2/FiO2 >100 at baseline),
    2. Persistent respiratory distress while receiving oxygen (persistent marked dyspnea,use of accessory respiratory muscles, paradoxical respiratory movements),
    3. Transfer to the intensive care unit for intubation,
    4. Death.

  4. Cumulative incidence of resolution of ARDS (defined as PaO2/FiO2 ≥200 in room air) [ Time Frame: Through day 44 ]
  5. Cumulative incidence of freedom from oxygen requirement [ Time Frame: Through day 44 ]
  6. Proportion of patients requiring invasive mechanical ventilation due to worsening of ARDS [ Time Frame: Within 14 days after inclusion in the study ]
  7. Proportion of patients requiring non-invasive mechanical ventilation (NIV) due to worsening of ARDS [ Time Frame: Within 14 days after inclusion in the study ]
  8. Proportion of patients developing thrombotic microangiopathies [ Time Frame: Through day 44 ]
  9. Changes in PaO2 and PaO2/FIO2 [ Time Frame: Through day 44 ]
  10. Changes in quick Sequential Organ Failure Assessment Score (qSOFA: respiratory rate, systolic blood pressure, Glasgow Coma Scale (GCS) [ Time Frame: Through day 44 ]
  11. Changes in maximal and minimal cardiovascular parameters: Respiratory rate [ Time Frame: Through day 44 ]
  12. Changes in maximal and minimal cardiovascular parameters: Heart Rate [ Time Frame: Through day 44 ]
  13. Changes in levels of biomarkers of inflammation (CBC, CRP, Ferritin, Procalcitonin, D-dimers, LDH) [ Time Frame: On days 0, 1, 2, 4, 7, 10, 14, 21 and 44 ]
  14. Length of stay in ICU [ Time Frame: Through day 44 ]
  15. Cumulative incidence of discharge from hospital [ Time Frame: Through day 44 ]
  16. Number of adverse events [ Time Frame: Through day 44 ]
  17. Changes in levels of anti-drug antibodies [ Time Frame: On day 0 , 14 and 44 ]
  18. Changes in levels of biomarkers of complement activity: C3, C3a, C5a, sC5b-9 [ Time Frame: On days 0, 1, 2, 4, 7, 10, 14, 21 and 44 ]
  19. Changes in levels of biomarkers of cytokine release syndrome: IL-1, IL-6, IL-12 [ Time Frame: On days 0, 1, 2, 4, 7, 10, 14, 21 and 44 ]
  20. Changes in levels of Club Cell protein CC16 (biomarker of lung damage ) [ Time Frame: On days 0, 1, 2, 4, 7, 10, 14, 21 and 44 ]
  21. Changes in levels of AMY-101 plasma level [ Time Frame: On days 1, 2, 4, 7, 10, 14, 15, 21 ]
