Early administration of lopinavir/ritonavir plus hydroxych loroquine does not alter the clinical course of SARS-CoV-2 infection: a retrospective cohort study
Late stage study of hospitalized patients comparing treatment starting within 5 days versus later. Note that "early" here is only relative - all patients are hospitalized so this is "late" and "very late". The "early" treatment group is significantly older. Severe adverse events attributed by authors to concurrent administration of LPV, making it difficult to make conclusions about HC Q.
