About

This is a phase II, randomized, two-armed, double-blind, placebo-controlled trial designed to evaluate the safety, tolerability, and immunogenicity of a candidate adjuvanted recombinant SARS-CoV-2 spike (S) protein subunit vaccine (SpikoGen) produced by CinnaGen Co. 400 adult individuals receive either SARS-CoV-2 recombinant spike protein (25 µg) with Advax-SM adjuvant (15 mg) or saline placebo in a 3:1 ratio. The injection is given in two doses with a 21-day interval in the deltoid muscle of the non-dominant arm. The randomization was stratified by age (<65 or ≥65) and health conditions of potential risk for severe COVID-19. Participants will be visited at two weeks and will be followed up for six months after the second dose of the study intervention. Study hypotheses include: The adjuvanted COVID-19 vaccine candidate is safe and tolerable in adult subjects. The adjuvanted COVID-19 vaccine candidate induces strong immunogenicity against SARS-CoV-2 in adult subjects.
