COVID-19 Clinical Trial
Official title:
An Exploratory, Randomized, Double-Blind, Dose-Ranging Study to Evaluate the Safety and Immunogenicity of TI-0010 Vaccine to Prevent COVID-19 Caused by SARS-CoV-2 in Healthy Adults Aged 18-59 Years
This study is a randomized, double-blind, placebo controlled clinical exploratory study to evaluate the safety, tolerability and immunogenicity of TI-0010 vaccine in healthy adults aged 18-59. TI-0010 was manufactured by Therorna Inc. TI-0010 is a novel lipid nanoparticles (LNP) -encapsulated circRNA-based vaccine targeting RBD of SARS-CoV-2. Up to one hundred subjects will be enrolled into one of 4 cohorts. Low-dose(Dose Level 1) is for Cohort 1 and Cohort 2 , and the high dose (Dose Level 2) for Cohort 3 and Cohort 4. Cohort 1 and Cohort 3 receive 2 doses (with a 28 day interval) via intramuscular injection respectively, and Cohort 2 and Cohort 4 receive 1 dose via intramuscular injection respectively. Participants are randomized to receive TI-0010 or placebo in a 4:1 ratio.

Participants are randomized to receive TI-0010 or placebo in a 4:1 ratio. Follow-up visits will occur Days 3,7,14 and 28 post each vaccination, as well as 3, 6, 9 and 12 months for the single dose recipients after vaccination and for those who receive two doses post the second vaccination. The primary objective is to evaluate the safety and tolerability of the TI-0010 vaccine in adults within 28 days post each vaccination. The secondary objective is to evaluate the humoral and cellular immune responses of the TI-0010 vaccine in adults after a single dose or two doses of vaccination, to evaluate the safety of the TI-0010 vaccine within 1 year after vaccination in the adult population and to evaluate the immune persistence of TI-0010 vaccine after a single dose and two doses of administration. ;
