Retrospective 113 lung transplant recipients with mild-to-moderate COVID-19 showing higher mortality with remdesivir and molnupiravir in unadjusted analysis, with statistical significance for remdesivir. mAb PrEP and treatment and the dominant variant favored molnupiravir compared with the control group, however they favored the control group compared with remdesivir.

Potential risks include the creation of dangerous variants, and mutagenicity, carcinogenicity, teratogenicity, and embryotoxicity1-10. Multiple analyses have identified variants potentially created by molnupiravir11-14.

Introduction: Remdesivir (REM) and molnupiravir (MOL) are commonly used to treat lung transplant recipients (LTRs) with COVID-19; however, the clinical efficacy of these medications is yet to be compared. In this retrospective cohort study, we compared the clinical outcomes between LTRs with mild-tomoderate COVID-19 treated with REM and those treated with MOL. Methods and Results: Between March 2020 and August 2022, 195 LTRs developed COVID-19 at our center. After excluding 82 who presented with severe disease requiring hospitalization, the remaining 113 were included in the analysis: 54 did not receive antiviral treatment, 30 were treated with REM, and 29 were treated with MOL. Adjusted multivariable logistic regression analysis showed similar rates of hospitalization (adjusted odds ratio (aOR) 1.169, [95% confidence interval (95% CI) 0.105-12.997, p = 0.899], ICU admission (aOR 0.822, 95% CI 0.042-16.220, p = 0.898), mechanical ventilation (aOR 0.903, 95% CI 0.015-55.124, p = 0.961), and COVID-19related mortality (aOR 0.822, 95% CI 0.042-16.220, p = 0.898) between LTRs treated with REM and those treated with MOL for mild-to-moderate COVID-19, irrespective of SARS-CoV-2 strain. Conclusion: MOL may be a suitable alternative to REM to treat LTRs with mildto-moderate COVID-19, and the choice of antiviral therapy can be driven by practical considerations such as route of administration and drug availability.

Ethics statement The studies involving humans were approved by The Institutional Review Board of St. Joseph's Hospital and Medical Center.
