Study to Evaluate the Viral Load Reduction of a Single Dose of Plitidepsin in Adult Patients With COVID-19

The main objective of this study is to evaluate the efficacy and safety of a single dose of plitidepsin in order to reduce the viral load and symptoms recovery after discharge from Emergency.

More than a year after the appearance of the new SARS-COV-2 coronavirus, the search continues for an effective treatment to reduce the symptoms and infectivity of a pandemic that has left behind more than 120 million cases and more than 2.5 million deaths. Plitidepsin is an approved multiple myeloma drug in Australia that in both preclinical and clinical studies has shown a clear antiviral effect against SARS.COV-2 and, in this study, we propose to evaluate the efficacy of a single dose of plitidepsin 7.5 mg administered in 90 minutes through decreasing viral load at day 6 and symptoms recovery at day 14 with after the patient is discharged from Emergency.

FINE criteria ≤3). 6. Men and women with reproductive capacity must agree to use highly effective contraceptive methods during their participation in the study and in the 6 months following the administration of plitidepsin. 7. Women participating in the study with reproductive ability must have a negative pregnancy test at enrollment. Exclusion Criteria: 1. Patients participating in some other clinical trial for COVID-19 infection. 2. Patients requiring hospital admission. 3. Patients with evidence of pneumonia on recent imaging within the previous 24 hours, with respiratory failure (PO2<60 or SatO2 <92), and with a FINE score > 3. 4. Patient without analytical stability: 1. Haemoglobin < 9 g/dL. 2. Neutrophils < 1000/mm3. 3. Platelets < 100,000/mm3. 4. Lymphopenia < 800/μL. 5. GOT / GPT > 3 X ULN. 6. Bilirubin > 1 X ULN. 7. CPK > 2.5 X ULN. 8. Creatinine clearance < 30 ml/min. 9. BUN > 20 mg/dl. 10. Troponin elevation > 1.5 x ULN. 5. Patients who will not receive the vaccine for at least 30 days following emergency discharge. 6. Patients who are receiving or have received treatment with chloroquine and derivatives in the previous 50 days. 7. Patients living in an isochrone of more than 30 minutes by car, which precludes follow-up at home and the collection of the necessary samples at repeated visits. 8. Patients for whom it is foreseen that follow-up is not going to be possible for any reason (absence from home, inability to open the door at the request, etc.). 9. Patients with any known alteration of immunity including current treatment with corticoids, or with monoclonal antibody or any drug that alters the patient's immunity. 10. Clinically relevant heart disease (NYHA >2). 11. Relevant electrocardiographic abnormalities: - 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; or - QT interval corrected using Fridericia's formula (QTcF) prolongation >450 msec for males or >470 msec for females, based on triplicate ECG at screening. 12.

Patients requiring or being treated with potent CYP3A4 inhibitors and inducers. 14. Patients with pulmonary thromboembolism or deep vein thrombosis, who would require new treatment with anticoagulants, which could interfere with study results by including an accepted COVID treatment in one of the arms. 15. Patients who for any reason should not be included in the study according to the evaluation of the research team.
