TRIAL DESCRIPTION
Public title A Global Multi-center, Randomized, Blinded, Placebo-controlled Phase 3 Clinical Study to Evaluate the Efficacy, Safety and Immunogenicity of SARS-CoV-2 mRNA Vaccine (LVRNA009) for the Prevention of COVID-19 in Participants Aged 18 Years and Older
Official scientific title A Global Multi-center, Randomized, Blinded, Placebo-controlled Phase 3 Clinical Study to Evaluate the Efficacy, Safety and Immunogenicity of SARS-CoV-2 mRNA Vaccine (LVRNA009) for the Prevention of COVID-19 in Participants Aged 18 Years and Older
Brief summary describing the background and objectives of the trial The outbreak of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in December 2019 has rapidly become a global epidemic, causing heavy economic stress, medical burden and a serious threat to human survival and health for people worldwide. It is widely believed that effective vaccination plays a crucial role in preventing and controlling the spread of COVID-19. Thus more potent and thermostable vaccine with excellent safety profile is highly-demanded. The investigational vaccine is a linear mRNA molecule obtained by using recombinant gene technology, the safety and immunogenicity of which have been preliminarily evaluated in a phase 1 study in China. In this phase 3 study, we will further confirm its protective efficacy against COVID-19 in some African and Asian countries where the disease is still in pandemic.
