$ARCT $CSLLY Arcturus Therapeutics, CSL publish data on booster dose of ARCT-154
CSL and Arcturus Therapeutics announced the publication in Lancet Infectious Diseases of a Phase 3 study showing that a booster dose of ARCT-154, a novel, self-amplifying messenger RNA, or sa-mRNA, vaccine, elicited a numerically higher immune response against the original Wuhan-Hu-1 virus strain, and a superior immune response against Omicron BA.4/5 subvariant of SARS-CoV-2 virus compared to a booster dose of the conventional mRNA vaccine Comirnaty.

The study included healthy adults initially immunized with two doses of an mRNA vaccine; and then a third dose of Comirnaty at least three months prior to the booster dose of either ARCT-154 or Comirnaty in the study. Both vaccines were well-tolerated, with no causally associated severe or serious adverse events. The study was conducted in partnership with Meiji Seika Pharma...
