Abstract

Background

Evidence for the effect of favipiravir treatment of acute COVID-19 on recovery, hospital admissions and longer-term outcomes in community settings is limited.

Methods

In this multicentre. open-label, multi-arm, adaptive platform randomised controlled trial participants aged ≥18 years in the community with a positive test for SARS-CoV-2 and symptoms lasting ≤14 days were randomised to: usual care; usual care plus favipiravir tablets (loading dose of 3600 mg in divided doses on day one, then 800 mg twice a day for four days); or, usual care plus other interventions. Co-primary endpoints were time to first self-reported recovery and hospitalisation/death related to COVID-19, within 28 days, analysed using Bayesian models. Recovery at six months was the primary longer-term outcome. Trial registration: ISRCTN86534580.

Findings

The primary analysis model included 8811 SARS-CoV-2 positive mostly COVID vaccinated participants, randomised to favipiravir (n = 1829), usual care (n = 3256), and other treatments (n = 3726). Time to self-reported recovery was shorter in the favipiravir group than usual care (estimated hazard ratio 1·23 [95% credible interval 1·14 to 1·33]), a reduction of 2·98 days [1·99 to 3·94] from 16 days in median time to self-reported recovery for favipiravir versus usual care alone. COVID-19 related hospitalisations/deaths were similar (estimated odds ratio 0·99 [0·61 to 1·61]; estimated difference 0% [−0·9% to 0·6%]). 14 serious adverse events occurred in the favipiravir group and 4 in usual care. By six months, the proportion feeling fully recovered was 74·9% for favipiravir versus 71·3% for usual care (RR = 1·05, [1·02 to 1·08]).

Interpretation

In this open-label trial in a largely vaccinated population with COVID-19 in the community, favipiravir did not reduce hospital admissions, but shortened time to recovery and had a marginal positive impact on long term outcomes.

PRINCIPLE 是一项开放标签、随机对照、适应性平台试验,对短期和长期疗效进行研究。
背景:在社区环境中,法非拉韦治疗急性COVID-19对康复、入院和长期疗效的影响证据有限:在这项多中心、开放标签、多臂、适应性平台随机对照试验中,年龄≥18岁、SARS-CoV-2检测呈阳性且症状持续时间≤14天的社区参与者被随机分配到:常规治疗;常规治疗加法非拉韦片(第一天分次服用3600毫克的负荷剂量,然后在四天内每天两次,每次800毫克);或常规治疗加其他干预措施。共同主要终点是28天内首次自我报告痊愈和因COVID-19住院/死亡的时间,采用贝叶斯模型进行分析。6个月后的康复是主要的长期结果:ISRCTN86534580.Findings:主要分析模型包括8811名SARS-CoV-2阳性、大部分接种过COVID疫苗的参与者,他们随机接受了法非拉韦(1829人)、常规治疗(3256人)和其他治疗(3726人)。与常规治疗相比,法匹拉韦组的自我报告康复时间更短(估计危险比为1-23[95%可信区间为1-14至1-33]),与常规治疗相比,法匹拉韦组的自我报告康复时间中位数从16天缩短了2-98天[1-99至3-94]。与COVID-19相关的住院/死亡情况相似(估计几率比0-99 [0-61至1-61];估计差异0% [-0-9%至0-6%])。法非拉韦组发生了14起严重不良事件,常规治疗组发生了4起。6个月后,感觉完全康复的比例为:法非拉韦组74-9%,常规治疗组71-3%(RR=1-05,[1-02至1-08]):这项开放标签试验主要针对社区中接种过COVID-19疫苗的人群,在这项试验中,法匹拉韦未减少入院人数,但缩短了康复时间,并对长期疗效产生了微弱的积极影响。
