ABSTRACT

BACKGROUND: Coronavirus-associated acute respiratory distress syndrome (CARDS) has limited effective therapy to date. NLRP3 inflammasome activation induced by SARS-CoV-2 in COVID-19 contributes to cytokine storm. METHODS: This randomised, multinational study enrolled hospitalised patients (18-80 years) with COVID-19-associated pneumonia and impaired respiratory function. Eligible patients were randomised (1:1) via Interactive Response Technology to DFV890 + standard-of-care (SoC) or SoC alone for 14 days. Primary endpoint was APACHE II score at Day 14 or on day-of-discharge (whichever-came-first) with worst-case imputation for death. Other key assessments included clinical status, CRP levels, SARS-CoV-2 detection, other inflammatory markers, in-hospital outcomes, and safety. FINDINGS: Between May 27, 2020 and December 24, 2020, 143 patients (31 clinical sites, 12 countries) were randomly assigned to DFV890 + SoC (n = 71) or SoC alone (n = 72). Primary endpoint to establish clinical efficacy of DFV890 vs. SoC, based on combined APACHE II score, was not met; LSM (SE), 8·7 (1.06) vs. 8·6 (1.05); p = 0.467. More patients treated with DFV890 vs. SoC showed ≥ 1-level improvement in clinical status (84.3% vs. 73.6% at Day 14), earlier clearance of SARS-CoV-2 (76.4% vs. 57.4% at Day 7), and mechanical ventilation-free survival (85.7% vs. 80.6% through Day 28), and there were fewer fatal events in DFV890 group (8.6% vs. 11.1% through Day 28). DFV890 was well tolerated with no unexpected safety signals. INTERPRETATION: DFV890 did not meet statistical significance for superiority vs. SoC in primary endpoint of combined APACHE II score at Day 14. However, early SARS-CoV-2 clearance, improved clinical status and in-hospital outcomes, and fewer fatal events occurred with DFV890 vs. SoC, and it may be considered as a protective therapy for CARDS. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04382053.

ABSTRACT

Objetivos: Evaluar el valor pronóstico de una nueva variable derivada de la prueba de ejercicio cardiopulmonar (PECP), el poder cardíaco máximo (PCmáx) en el ejercicio pico. Material y métodos: Se evaluaron prospectivamente pacientes con insuficiencia cardíaca, en quienes se determinaron el VO2 máx, el PCmáx (pulso de oxígeno Î tensión arterial media) y la reserva cardíaca(PCmáx - basal). Se compararon los valores de acuerdo con la ocurrencia o no de eventos (internación por IC o muerte). Se evaluó el valor incremental a través de curvas ROC y la asociación de sus puntos de corte con eventos (log rank test y ajuste por confundidores por regresión de Cox). Punto final combinado: internación por IC y/o muerte. Resultados: Población: 157 pacientes, hombres 83,4 por ciento, edad 59 ± 10 años, clase funcional III/IV 22,2 por ciento, deterioro severo del VI 56,7 por ciento, eventos: 22,9 por ciento. Seguimiento promedio: 9 meses. Los pacientes con eventos presentaron menores valores de: VO2 máx (11,8 versus 14,9 ml/kg/min, p < 0,001), PCmáx (831 versus 1.079 watts, p = 0,003) y reserva cardíaca (465 versus 676 watts, p = 0,002). Áreas ROC: (VO2 máx: 0,73; PCmáx 0,68; RC 0,68, p = 0,34 entre áreas). Riesgo de eventos: para VO2 máx < 14 ml/kg/min HR 3,93 (IC 95 por ciento 1,89-8,20), p < 0,001; PCmáx < 780 watts HR 2,78 (IC 95 por ciento 1,42-5,43), p = 0,003; y RC < 350 watts HR 2,75 (IC 95 por ciento 1,42-5,35), p = 0,003. La incidencia de eventos fue del 8,54 por ciento en pacientes con VO2 y PC normales, 30,30 por ciento sólo un índice alterado: HR 3,09 (IC 95 por ciento 1,16-8,25), p = 0,024, y 45,24 por ciento con ambos alterados: HR 5 (IC 95 por ciento 1,81-13,75), p = 0,002. Conclusiones: La determinación del PCmáx es otra variable para determinar en la PECP que podría aportar valor pronóstico incremental agregado a otros parámetros clásicos.
