Multicenter Study Clinical TrialA Prospective, Randomized, Open-Label Trial of Early versus Late Favipiravir Therapy in Hospitalized Patients with COVID-19.
Favipiravir is an oral broad-spectrum inhibitor of viral RNA-dependent RNA polymerase that is approved for treatment of influenza in Japan. We conducted a prospective, randomized, open-label, multicenter trial of favipiravir for the treatment of COVID-19 at 25 hospitals across Japan. Eligible patients were adolescents and adults admitted with COVID-19 who were asymptomatic or mildly ill and had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1. ⋯ During therapy, 84.1% developed transient hyperuricemia. Favipiravir did not significantly improve viral clearance as measured by reverse transcription-PCR (RT-PCR) by day 6 but was associated with numerical reduction in time to defervescence. Neither disease progression nor death occurred in any of the patients in either treatment group during the 28-day participation. (This study has been registered with the Japan Registry of Clinical Trials under number jRCTs041190120.).

Outcomes in Participants with Renal Impairment from a Phase 3 Clinical Trial for Ceftolozane/Tazobactam Treatment of Nosocomial Pneumonia (ASPECT-NP).
In the phase 3 ASPECT-NP trial (NCT02070757), ceftolozane/tazobactam (C/T) was noninferior to meropenem for treatment of Gram-negative ventilated hospital-acquired bacterial pneumonia and ventilator-associated bacterial pneumonia (vHABP/VABP). Here, we report outcomes in participants from ASPECT-NP with renal impairment (RI). Participants were categorized by their baseline renal function as follows: normal renal function (NRF; creatinine clearance [CLCR], ≥80 ml/min), mild RI (CLCR, >50 to <80 ml/min), moderate RI (CLCR, ≥30 to ≤50 ml/min), and severe RI (CLCR, ≥15 to <30 ml/min). ⋯ Small sample sizes in the RI groups resulted in large 95% confidence intervals (CIs), limiting conclusive interpretation of the analysis. Both drugs were well tolerated across all renal function groups. Overall, these results support the use of the study dosing regimens of C/T for treatment of vHABP/VABP in patients with RI. (This study has been registered at ClinicalTrials.gov under identifier NCT02070757.).
