Investigating Otilimab in Patients With Severe Pulmonary COVID-19 Related Disease

OSCAR (Otilimab in Severe COVID-19 Related Disease) is a multi-center, double-blind, randomized, placebo-controlled trial to assess the efficacy and safety of otilimab for the treatment of severe pulmonary COVID-19 related disease. The study is being conducted in 2 parts (Part 1 and Part 2). Otilimab is a human monoclonal anti-granulocyte macrophage colony stimulating factor (GM-CSF) antibody that has not previously been tested in participants with severe pulmonary COVID-19 related disease in Part 1. The aim of this study is to evaluate the benefit-risk of a single infusion of otilimab in the treatment of hospitalized participants with severe COVID-19 related pulmonary disease with new onset hypoxia requiring significant oxygen support or requiring early invasive mechanical ventilation (less than or equal to [<=] 48 hours before dosing). Participants will be randomized to receive a single intravenous (IV) infusion of otilimab or placebo, in addition to standard of care.

The 8-point scale was as follows: 1) Non-hospitalized, no limitation of activity; 2) Non-hospitalized,limitation of activity; 3) Hospitalized, no oxygen therapy; 4) Hospitalized, low-flow oxygen by mask or nasal prongs; 5) Hospitalized, highflow oxygen (>=15L/min), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BIPAP), non-invasive ventilation; 6) Hospitalized, intubation and mechanical ventilation; 7) Hospitalized, mechanical ventilation plus additional organ support; 8) Death. Percentage values are rounded off.

  29. Part 1: Time to Final ICU Discharge

    Time frame: Up to Day 28

  30. Part 2: Time to Final ICU Discharge

    Time frame: Up to Day 28

    Time to final ICU discharge was defined as the time from dosing to when the participant was discharged from the ICU for the last time up to (and including) Day 28. Median and inter-quartile range (first quartile and third quartile) of time to final ICU discharge is presented.

  31. Part 1: Time to First Discharge From Investigator Site up to Day 60

    Time frame: Up to Day 60

    Time to first discharge from investigator site was defined as the time (days) from dosing to when the participant was first discharged from investigator site (IS) up to (and including) Day 60. Median and inter-quartile range (first quartile and third quartile) of time to first discharge from investigator site is presented.

  32. Part 1: Time to First Discharge to Non-hospitalized Residence up to Day 60

    Time frame: Up to Day 60

    Time to first discharge to non-hospitalized residence was defined as the time (days) from dosing to when the participant was discharged to a non-hospitalized residence for the first time up to (and including) Day 60. Median and inter-quartile range (first quartile and third quartile) of time to first discharge to non-hospitalized residence is presented.

  33. Part 2: Time to First Discharge From Investigator Site up to Day 60

    Time frame: Up to Day 60

    Time to first discharge from investigator site was defined as the time (days) from dosing to when the participant was first discharged from investigator site up to (and including) Day 60. Median and inter-quartile range (first quartile and third quartile) of time to first discharge from investigator site is presented.

  34. Part 2: Time to First Discharge to Non-hospitalized Residence

    Time frame: Up to Day 60

    Time to first discharge to non-hospitalized residence was defined as the time (days) from dosing to when the participant was discharged to a non-hospitalized residence for the first time up to (and including) Day 60. Median and inter-quartile range (first quartile and third quartile) of time to first discharge to non-hospitalized residence is presented.

  35. Part 1: Number of Participants With Serious Adverse Events (SAEs) and Common (>=5%) Non-serious Adverse Events (Non-SAEs)

    Time frame: Up to Day 60

    An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose may result in death or is life-threatening or requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity or is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment or is associated with liver injury and impaired liver function. Number of participants with any SAE and common (>=5%) non-SAEs are presented.

  36. Part 2: Number of Participants With SAEs and Common (>=5%) Non-SAEs

    Time frame: Up to Day 60

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is defined as any untoward medical occurrence that, at any dose may result in death or is life-threatening or requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity or is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment or is associated with liver injury and impaired liver function. Number of participants with any SAE and common (>=5%) non-SAEs are presented.
