Main Objective: To determine the effect of FBR-002 compared to placebo on the WHO-CPS in participants hospitalized with COVID-19 in need of supplemental oxygen at Day 28 after randomization;Secondary Objective: To determine the effect of FBR-002 compared to placebo on: the WHO-CPS in participants hospitalized with COVID-19 in need of supplemental oxygen between Day 0 and Day 14 To determine the effect of FBR-002 on: •The need for SoC intensification up to Day 14 •The disease progression within 28 days after randomization. •The overall survival at 28, 60 and 90 days after randomization. •The mortality rate related to respiratory failure due to COVID-19 within 90 days after randomization. •The WHO-CPS at Day 60 after randomization. •The time to hospital discharge within 60 days post-randomization. •The frailty of participants •Viral variants and viral load reduction. •The incidence and time to being free of any respiratory support. •SpO2/FiO2-ratio at days 3, 5 and 8 after randomization. •The occurrence of clinical and laboratory adverse events, including serious adverse events especially those leading to discontinuation of study treatment or to death. ;Primary end point(s): The distribution of frequencies of the WHO-CPS from 1 to 10 at Day 28 after randomization;Timepoint(s) of evaluation of this end point: Day 28

Secondary end point(s): Key secondary endpoints: •[2.1.1] Mean area under the curve (AUC) of WHO-CPS Day 0 to Day 14 •[2.1.2] The distribution of frequencies of the WHO-CPS (from 1 to 10) at Day 14 after randomization Other secondary endpoints: •[2.2] Proportion of participants that needed a SoC intensification up to Day 14 •[2.3.1] Time from Day 0 to occurrence of disease progression within 28 days from randomization •[2.3.2] Percentage of participants who have progressed their WHO-CPS to more or equal to 6 within 7, 14 and 28 days after randomization •[2.4] Overall survival at 28, 60 and 90 days from randomization. •[2.5] Mortality rate related to respiratory failure due to COVID-19 up to 90 days from randomization. •[2.6] The distribution of frequencies of the WHO-CPS (from 1 to 10) at Day 60 after randomization •[2.7] Time from Day 0 to hospital discharge within 60 days post-randomization. •[2.8] Evolution of mean clinical frailty score from Day 0 to day 28 •[2.9.1] Variant identification determined at Day 1 and Day 14, or early discontinuation visit (EDV). •[2.9.2] Mean viral load as assessed by SARS-CoV-2 RT-qPCR during hospitalization. •[2.9.3] Association between FBR-002 treatment and the proportion of participants with a variant at Day 14 (or EDV) different from the one at Day 1 •[2.9.4] Association between viral load and baseline viral variant. •[2.10.1] Cumulative incidence of being free of any respiratory support •[2.10.2] Time to being free of any respiratory support. •[2.11] Mean changes from randomization of SpO2/FiO2-ratio at days 3, 5 and 8 after randomization. •[2.12] Occurrence of clinically significant laboratory abnormalities, and adverse events, including serious adverse events (SAEs) especially those leading to discontinuation of study treatment or to death. ;Timepoint(s) of evaluation of this end point: •[2.1.1] Day 0 to Day 14 •[2.1.2] at Day 14 •[2.2]Day 0 to Day 14 •[2.3.1] Day 0 to Day 28 •[2.3.2] Day 7, Day 14 and Day 28 •[2.4] Da
