Protocol summary

Study aim
Determining the effect of bosentan on clinical outcomes of hospitalized patients with COVID-19 infection in comparison with routine protocol
Design
Double-blind randomized controlled clinical trial
Settings and conduct
In this study, COVID-19 patients, hospitalized in Shahid Mostafa Khomeini and Imam Khomeini hospitals with the mentioned inclusion and exclusion criteria will be studied. Bosentan and placebo tablets are similar, and patients and researchers are unaware of labeling. Bosentan 62.5 mg tablets will be given twice daily. Patients are followed up daily.

Inclusion Criteria: • Written informed consent; Age over 18 years; Laboratory-confirmed SARS-CoV-2 infection; Exclusion Criteria: • Pregnancy; Lactation; Glibenclamide Consumption; Cyclosporine Consumption; Aminotransferases > 3 times normal; Allergy to bosentan
Intervention groups
Oral Bosentan 62.5 mg, twice daily, for 30 days.
Main outcome variables
The time to clinical improvement, defined as the time from randomization to an improvement of two points (from the status at randomization) on a WHO 11 point clinical progression scale or live discharge from the hospital, whichever came first.

Randomization (investigator's opinion)
Randomized
Randomization description
Permuted Block Randomization will be used for random allocation. The size of the blocks will randomly selected. There are 4, random blocks, each has an equal number of interventions and controls. In the 4 blocks, two allocations are considered for the intervention group and two allocations for the control group. Random Allocation Software will be used for this purpose. The concealment will be done using sequentially numbered, sealed envelopes.
Blinding (investigator's opinion)
Double blinded
Blinding description
Blinding in this study is double blind that the drug and placebo are labeled as "Group A" and "Group B". They are quite similar in appearance and the person participating in the study and the person distributing the medicine does not know about this labeling.
