This article is a Preprint
Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
Background:
Lopinavir/ritonavir, lopinavir/ritonavir-interferon (IFN)-beta-1a and hydroxychloroquine efficacy for COVID-19 have been evaluated, but detailed evaluation is lacking.Objective:
To determine the efficacy of lopinavir/ritonavir, lopinavir/ritonavir-IFN-beta-1a, hydroxychloroquine or remdesivir for improving the clinical, virological outcomes in COVID-19 inpatients.Design:
Open-label, randomized, adaptive, controlled trial.Setting:
Multi-center trial with patients from France.Participants:
583 COVID-19 inpatients requiring oxygen and/or ventilatory support Intervention Standard of care (SoC, control), SoC plus lopinavir/ritonavir (400 mg lopinavir and 100 mg ritonavir every 12h for 14 days), SoC plus lopinavir/ritonavir plus IFN-beta-1a (44 micrograms of subcutaneous IFN-beta-1a on days 1, 3, and 6), SoC plus hydroxychloroquine (400 mg twice on day 1 then 400 mg once daily for 9 days) or SoC plus remdesivir (200 mg intravenously on day 1 then 100 mg once-daily for hospitalization duration or 10 days). Measurements The primary outcome was the clinical status at day 15, measured by the WHO 7-point ordinal scale. Secondary outcomes included SARS-CoV-2 quantification in respiratory specimens and safety analyses.Results:
Adjusted Odds Ratio (aOR) for the WHO 7-point ordinal scale were not in favor of investigational treatments lopinavir/ritonavir versus control, aOR 0.83, 95%CI, 0.55 to 1.26, P=0.39; lopinavir/ritonavir-IFN-beta-1a versus control, aOR 0.69, 95%CI, 0.45 to 1.04, P=0.08; hydroxychloroquine versus control, aOR 0.93, 95%CI, 0.62 to 1.41, P=0.75. No significant effect on SARS-CoV-2 RNA clearance in respiratory tract was evidenced. Lopinavir/ritonavir-containing treatments were significantly associated with more SAE.Limitations:
Not a placebo-controlled, no anti-inflammatory agents tested.Conclusion:
No improvement of the clinical status at day 15 nor SARS-CoV-2 RNA clearance in respiratory tract specimens by studied drugs. This comforts the recent Solidarity findings. Registration NCT04315948.Funding:
