There is one clinical trial.
In December 2019, viral pneumonia caused by a novel beta-coronavirus (Covid-19) broke out in Wuhan, China. Some patients rapidly progressed and suffered severe acute respiratory failure and died, making it imperative to develop a safe and effective vaccine to treat and prevent severe Covid-19 pneumonia. Based on detailed analysis of the viral genome and search for potential immunogenic targets, a synthetic minigene has been engineered based on conserved domains of the viral structural proteins and a polyprotein protease. The infection of Covid-19 is mediated through binding of the Spike protein to the ACEII receptor, and the viral replication depends on molecular mechanisms of all of these viral proteins. This trial proposes to develop and test innovative Covid-19 minigenes engineered based on multiple viral genes, using an efficient lentiviral vector system (NHP/TYF) to express viral proteins and immune modulatory genes to modify dendritic cells (DCs) and to activate T cells. In this study, the safety and efficacy of this LV vaccine (LV-SMENP) will be investigated.
Description: A decline of 2 points on the 7-point scale from admission means better outcome. The 7-category ordinal scale that ranges from 1 (discharged with normal activity) to 7 (death).
Measure: Clinical improvement based on the 7-point scale Time: 28 days after randomizationDescription: Murray lung injury score decrease more than one point means better outcome. The Murray scoring system range from 0 to 4 according to the severity of the condition.
Measure: Lower Murray lung injury score Time: 7 days after randomizationDescription: Number of deaths during study follow-up
Measure: 28-day mortality Time: Measured from Day 0 through Day 28Description: Duration of mechanical ventilation use in days. Multiple mechanical ventilation durations are summed up.
Measure: Duration of mechanical ventilation Time: Measured from Day 0 through Day 28Description: Days that a participant spent at the hospital. Multiple hospitalizations are summed up.
Measure: Duration of hospitalization Time: Measured from Day 0 through Day 28Description: Proportion of patients with negative RT-PCR results of virus in upper and/or lower respiratory tract samples.
Measure: Proportion of patients with negative RT-PCR results Time: 7 and 14 days after randomizationDescription: Proportion of patients in each category of the 7-point scale, the 7-category ordinal scale that ranges from 1 (discharged with normal activity) to 7 (death).
Measure: Proportion of patients in each category of the 7-point scale Time: 7,14 and 28 days after randomizationDescription: Proportion of patients with different inflammation factors in normalization range.
Measure: Proportion of patients with normalized inflammation factors Time: 7 and 14 days after randomizationDescription: Frequency of vaccine/CTL Events
Measure: Frequency of vaccine/CTL Events Time: Measured from Day 0 through Day 28Description: Frequency of Serious vaccine/CTL Events
Measure: Frequency of Serious vaccine/CTL Events Time: Measured from Day 0 through Day 28
