入选标准
- •Signed informed consent obtained prior to initiation of any study-specific procedures and study treatment.

- •Patient meets category 5 on the 11-point WHO Clinical Progression Scale: requires hospitalisation and oxygen by mask or nasal prongs/cannula.
- •A maximum of 14 days from onset of COVID-19 symptoms to initiation of study treatment on Day
- •Male or female aged ≥18 years.
- •Adequate bone marrow, liver, kidney, and metabolic function, defined by the following tests performed at local laboratory:
- •Absolute neutrophil count ≥500/mm^3 (0.5 x 10^9/L).

- •Calculated creatinine clearance ≥30 mL/min (Cockcroft-Gault equation).
- •Creatine phosphokinase (CPK) ≤2.5 x ULN except if the patient has had recent (i.e., in the last week) shivering episodes or trauma. In that case, the level of CPK should be ≤5 x ULN.

Patients in the control arm must use effective contraception during the time indicated in the approved product information (summary of product characteristics [SmPC] or leaflet).

- •Prior administration of dexamethasone or equivalent glucocorticoid might be acceptable if:
- •The total daily dose is not higher than 10 mg of dexamethasone phosphate (equivalent to dexamethasone base 8.25 mg/day) or equivalent glucocorticoids.
- •The duration of the treatment does not exceed 72 hours prior to study treatment Day
- •Prior administration of an antiviral might be acceptable in the following circumstances:
- •For small molecules (e.g., remdesivir, molnupiravir, nirmaltrevir/ritonavir), they must have been given for an earlier stage of the disease, outside a clinical trial, and there should be a documentation of objective clinical deterioration plus evidence of persisting positivity for SARS-CoV-2 in appropriate biological samples. Last dose of previous antiviral drugs should have been administered at least 24 h before randomisation.
- •For antiviral monoclonal antibodies, they must have been given for an earlier stage of the disease (including pre-exposure prophylaxis), outside a clinical trial, and there should be a documentation of objective clinical deterioration plus evidence of persisting positivity for SARS-CoV-2 in appropriate biological samples. Last dose of antiviral monoclonal antibodies should have been administered at least 1 week before randomisation.
- •Patients receiving treatment with chloroquine or derivatives within 8 weeks before enrolment or during the study.
- •Patients receiving treatment with strong cytochrome P450 3A4 (CYP3A4) inhibitors or inducers.
- •Viral illness (other than COVID-19) requiring therapy, except for patients with treated and adequately controlled (undetectable) human immunodeficiency virus infection.
- •Patients with uncontrolled known primary or secondary immunodeficiency, including chronic treatment with glucocorticoids (i.e., prednisone at a daily dose of >10 mg for >1 month, or another glucocorticoid at equipotent dose).
- •Any of the following cardiac conditions or risk factors:
- •Sinus bradycardia (<50 beats/min), sinus nodal dysfunction (sick sinus disease), atrioventricular block of any degree (PR >200 msec), or any other bradyarrhythmia (<50 beats/min), except for patients with permanent pacemakers;
- •Cardiac infarction, cardiac surgery or cardiac insufficiency episode within the last 6 months;
- •Known abnormal value of left ventricular ejection fraction (LVEF <low limit of normal (LLN)), unless documented confirmation of recovery (LVEF >LLN) in the previous month;
- •QT interval corrected using Fridericia's formula (QTcF) >450 msec for males or >470 msec for females;
- •History of known congenital or acquired QT prolongation;
- •Uncorrected hypokalaemia, hypocalcaemia (adjusted) and/or hypomagnesemia at screening;
- •Troponin test performed at local laboratory >1.5 x ULN; or
- •Need for an unreplaceable drug that prolongs QT and it is clearly associated with a known risk for torsades de pointes (TdP); in case of being already on treatment with these aforementioned drugs, a minimum of 4 half-lives of the drug is required before replacement (if feasible).
- •Hypersensitivity to the active ingredient or any of the excipients (mannitol, macrogolglycerol hydroxystearate, and ethanol) or patients for whom dexamethasone, antihistamine H1/H2 or antiserotoninergic agents are contraindicated.
- •Females who are pregnant (negative serum or urine pregnancy test required for all females of child-bearing potential at screening) or breast feeding.
- •Females and males with partners of child-bearing potential (females who are not surgically sterile or postmenopausal defined as amenorrhea for >12 months) who are not using at least 1 protocol specified method of contraception.
- •Any other clinically significant medical condition (including major surgery within the last 3 weeks before screening) or laboratory abnormality that, in the opinion of the investigator, would jeopardise the safety of the patient or potentially impact on patient compliance or the safety/efficacy observations in the study.

Time to sustained withdrawal of oxygen supplementation (in days) with no subsequent reutilisation during remaining study period is defined as the first day, from randomisation through completion of the study, on which a patient i. satisfies categories 0 to 4 on the 11-point WHO Clinical Progression Scale, and ii. has no subsequent reutilisation of oxygen supplementation (5 to 10 on the 11-point WHO Clinical Progression Scale). The WHO clinical progression scale provides a measure of illness severity across a range from 0 (uninfected) to 10 (dead).
