A Trial of Remdesivir in Adults With Severe COVID-19
- Conditions
- COVID-19RemdesivirSARS-CoV-2
- Interventions
- Registration Number
- NCT04257656
- Lead Sponsor
- Capital Medical University
- Brief Summary
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia of unknown cause. In a short time, Chinese scientists had shared the genome information of a novel coronavirus (SARS-CoV-2) from these pneumonia patients and developed a real-time reverse transcription PCR (real-time RT-PCR) diagnostic assay.
Given no specific antiviral therapy for COVID-19 and the ready availability of remdesvir as a potential antiviral agent, based on pre-clinical studies in SARS-CoV and MERS-CoV infections, this randomized, controlled, double blind trial will evaluate the efficacy and safety of remdesivir in patients hospitalized with severe COVID-19.
- Detailed Description
In December 2019, Wuhan, in Hubei province, China, became the center of an outbreak of pneumonia of unknown cause. In a short time, Chinese scientists had shared the genome information of a novel coronavirus (SARS-CoV-2) from these pneumonia patients and developed a real-time reverse transcription PCR (real-time RT-PCR) diagnostic assay.
Whilst the outbreak is likely to have started from a zoonotic transmission event associated with a large seafood market that also traded in live wild animals, it soon became clear that person-to-person transmission was also occurring. The number of cases of infection with COVID-19 identified in Wuhan increased markedly over the later part of January 2020, with cases identified in multiple other Provinces of China and internationally. Mathematical models of the expansion phase of the epidemic suggested that sustained person-to-person transmission is occurring, and the R-zero is substantially above 1, the level required for a self-sustaining epidemic in human populations.
The clinical spectrum of COVID-19 illness appears to be wide, encompassing asymptomatic infection, a mild upper respiratory tract infection, and severe viral pneumonia with respiratory failure and even death. Although the per infection risk of severe disease remains to be determined, case-fatality risk of 11-14% has been reported in several initial studies of seriously ill patients and case-fatality has been estimated approximately at 2% overall. Also the large number of cases in Wuhan has resulted in a large number of patients hospitalised with pneumonia requiring supplemental oxygen and sometimes more advance ventilator support.
This new coronavirus, and previous experiences with SARS and MERS-CoV, highlight the need for therapeutics for human coronavirus infections that can improve clinical outcomes, speed recovery, and reduce the requirements for intensive supportive care and prolonged hospitalisation.
Given no specific antiviral therapy for COVID-19 and the ready availability of remdesvir as a potential antiviral agent, based on pre-clinical studies in SARS-CoV and MERS-CoV infections, this randomized, controlled, double blind trial will evaluate the efficacy and safety of remdesivir in patients hospitalized with severe COVID-19.

- Primary Outcome Measures
Name Time Method Time to Clinical Improvement (TTCI) [Censored at Day 28] up to 28 days The primary endpoint is time to clinical improvement (censored at Day 28), defined as the time (in days) from randomization of study treatment (remdesivir or placebo) until a decline of two categories on a six-category ordinal scale of clinical status (1 ꞊ discharged; 6 ꞊ death) or live discharge from hospital.
Six-category ordinal scale:
6. Death; 5. ICU, requiring ECMO and/or IMV; 4. ICU/hospitalization, requiring NIV/ HFNC therapy; 3. Hospitalization, requiring supplemental oxygen (but not NIV/ HFNC); 2. Hospitalization, not requiring supplemental oxygen;
1. Hospital discharge or meet discharge criteria (discharge criteria are defined as clinical recovery, i.e. fever, respiratory rate, oxygen saturation return to normal, and cough relief).
Abbreviation: IMV, invasive mechanical ventilation; NIV, non-invasive mechanical ventilation; HFNC, High-flow nasal cannula.
- Secondary Outcome Measures
Name Time Method Clinical status days 7, 14, 21, and 28 Clinical status, assessed by the ordinal scale at fixed time points (days 7, 14, 21, and 28).
