Outcome Measures

Primary Outcomes (1)

  • Improvement of the absolute lymphocyte count (ALC) of lymphopenic (ALC≤1000/mm3) COVID-19 infected participants out to approximately 30 days following initial Study drug administration or Hospital discharge (HD), whichever occurs first

    A statistically significant increase of the absolute lymphocyte count (ALC) from randomization to day 30 or Hospital Discharge

    1 month

Secondary Outcomes (14)

  • To obtain "clinical improvement" as defined by an improvement in a 11-points WHO score for Clinical Assessment, through day 30 or HD.

    1 month

  • a significant decline of SARS-CoV-2 viral load through day 30 or HD

    1 month or HD (whichever occurs first)

  • frequency of secondary infections through day 45 compared tp placebo arm

    45 days

  • length of hospitalization compared to placebo arm

    45 days

  • length of stay in ICU compared to placebo arm

    45 days

  • +9 more secondary outcomes

Other Outcomes (1)

  • Safety assessment through incidence and scoring of grade 3-4 adverse events

    45 days
