Eligibility Inclusion Criteria: 1. Signed informed consent obtained prior to initiation of any study-specific procedures and study treatment. 2. Documented diagnosis of SARS-CoV-2 infection, determined by either qualitative polymerase chain reaction (PCR), antigen test by local laboratory, or any other validated method approved by the local health authority, from appropriate biological samples collected no more than 72 hours prior to study treatment on Day 1. 3. Patient meets category 5 on the 11-point WHO Clinical Progression Scale: requires hospitalisation and oxygen by mask or nasal prongs/cannula. 4. A maximum of 14 days from onset of COVID-19 symptoms to initiation of study treatment on Day 1. 5. Male or female aged =18 years. 6. 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). - Platelet count =75,000/mm^3 (75 x 10^9/L). - Alanine transaminase (ALT), aspartate transaminase (AST) =3 x upper limit of normal (ULN). - Serum bilirubin =1 x ULN (or direct bilirubin <1 x ULN when total bilirubin is above ULN). - 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.

Females of reproductive capacity must have a negative serum or urine pregnancy test by local laboratory at study enrolment and must be non-lactating. 9. Females and males with partners of child-bearing potential must use effective contraception while on study treatment and for 6 months after last dose of plitidepsin. 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). If no information is available in the approved product information, patients in the control arm must use effective contraception for at least one week after the study completion or the time indicated based on the investigator's discretion. Exclusion Criteria: 1. Subjects with a pre-baseline (i.e., in the month preceding the current COVID-19 infection) impairment in general health condition for whatever reason except COVID-19, with a severe dependency for daily living activities (Barthel index = 60/100) or chronic oxygen therapy. 2. Having received treatment for COVID-19 in another clinical trial in the prior 4 weeks, except documented allocation in a placebo arm. 3. Evidence of respiratory failure at the time of randomisation, based on resource utilisation requiring at least one of the following: endotracheal intubation and mechanical ventilation, oxygen delivered by high-flow nasal cannula, non-invasive positive pressure ventilation, ECMO, or clinical diagnosis of respiratory failure (i.e., clinical need for one of the aforementioned therapies, which could not be administered in a resource-limited setting). 4.

Patients receiving treatment with strong cytochrome P450 3A4 (CYP3A4) inhibitors or inducers. 8. Viral illness (other than COVID-19) requiring therapy, except for patients with treated and adequately controlled (undetectable) human immunodeficiency virus infection. 9. 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). 10. 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). 11. 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. 12. Females who are pregnant (negative serum or urine pregnancy test required for all females of child-bearing potential at screening) or breast feeding. 13. 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. 14.
