  1. Number of Participants With Adverse Events and Serious Adverse Events [ Time Frame: Screening to 28 (+3) days after last dose of acalabrutinib (for acalabrutinib + BSC participants) or to 38 (+3) days after randomization (for BSC alone participants) ]
  2. Percentage of Participants Alive and Free of Respiratory Failure at Day 28 [ Time Frame: At Day 28 ]
    Respiratory failure, is defined based on resource utilization of any of the following modalities: a) Endotracheal intubation and mechanical ventilation b) Oxygen delivered by highflow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20 L/min with fraction of delivered oxygen ≥0.5) c) Non-invasive positive pressure ventilation or continuous positive airway pressure d) Extracorporeal membrane oxygenation

  3. Percent Change From Baseline in C-reactive Protein. [ Time Frame: Days 3, 5, 7, 10, 14, 28 ]

    Baseline is defined as the result obtained on the date of randomization. If no result was obtained on the date of randomization, the last result prior to the date of randomization is used.

    Percent change from baseline at Day X is calculated by multiplying the following result by 100%: (Day X value - Baseline value)/Baseline value.

    The mean of this result for all analyzed patients is taken to get the mean percent change from baseline.


  4. Percent Change From Baseline in Ferritin [ Time Frame: Days 3, 5, 7, 10, 14, 28 ]

    Baseline is defined as the result obtained on the date of randomization. If no result was obtained on the date of randomization, the last result prior to the date of randomization is used.

    Percent change from baseline at Day X is calculated by multiplying the following result by 100%: (Day X value - Baseline value)/Baseline value.

    The mean of this result for all analyzed patients is taken to get the mean percent change from baseline.


  5. Percent Change From Baseline in Absolute Lymphocyte Count [ Time Frame: Days 3, 5, 7, 10, 14, 28 ]

    Baseline is defined as the result obtained on the date of randomization. If no result was obtained on the date of randomization, the last result prior to the date of randomization is used.

    Percent change from baseline at Day X is calculated by multiplying the following result by 100%: (Day X value - Baseline value)/Baseline value.

    The mean of this result for all analyzed patients is taken to get the mean percent change from baseline.


  6. Overall Survival [ Time Frame: From randomization until 90 days after randomization. Safety Issue: ]

  9. Number of Days Alive and Free of Respiratory Failure [ Time Frame: From randomization to 28 days after randomization. ]
    Respiratory failure, is defined based on resource utilization of any of the following modalities: a) Endotracheal intubation and mechanical ventilation b) Oxygen delivered by highflow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20 L/min with fraction of delivered oxygen ≥0.5) c) Non-invasive positive pressure ventilation or continuous positive airway pressure d) Extracorporeal membrane oxygenation

  10. Number of Days With Respiratory Failure [ Time Frame: From randomization to 28 days after randomization. ]
    Respiratory failure, is defined based on resource utilization of any of the following modalities: a) Endotracheal intubation and mechanical ventilation b) Oxygen delivered by high-flow nasal cannula (heated, humidified, oxygen delivered via reinforced nasal cannula at flow rates >20 L/min with fraction of delivered oxygen ≥0.5) c) Non-invasive positive pressure ventilation or continuous positive airway pressure d) Extracorporeal membrane oxygenation For participants who die (due to any cause) prior to Day 28, days from death to Day 28 are counted as days with respiratory failure. For participants in hospital and experiencing respiratory failure at the time they withdraw from the study, days from last known status to Day 28 are counted as days with respiratory failure.

  11. Number of Days Hospitalized [ Time Frame: From randomization to 28 days after randomization. ]

    For this summary, the hospitalization must be considered clinically indicated to count as a day hospitalized.

    For participants who die (due to any cause) prior to Day 28, days from death to Day 28 are counted as days hospitalized.

    For participants in hospital at the time they withdraw from the study, days from last known status to Day 28 are counted as days hospitalized.


  12. Number of Days in ICU [ Time Frame: From randomization to 90 days after randomization. ]

    For this summary, the ICU stay must be considered clinically indicated to count as a day in ICU.

    For participants who die (due to any cause) prior to Day 90, days from death to Day 90 are counted as days in ICU.


  13. Number of Days Alive Outside of Hospital [ Time Frame: From randomization to 28 days after randomization. ]
  14. Number of Days Alive Outside of Hospital [ Time Frame: From randomization to 90 days after randomization. ]

    Baseline is defined as the result obtained on the date of randomization.

    Percent change from baseline at Day X is calculated by multiplying the following result by 100%: (Day X value - Baseline value)/Baseline value.

    The mean of this result for all analyzed patients is taken to get the mean percent change from baseline.

    9-point category ordinal scale: 0. * Uninfected, no clinical or virological evidence of infection

    1. Ambulatory, no limitation of activities
    2. Ambulatory, limitation of activities
