New COVID-19 sa-mRNA Results from CSL and Arcturus Therapeutics Demonstrate Longer Duration of Immunity Compared to Conventional COVID-19 mRNA Vaccine Booster
Global biotechnology leader CSL (ASX:CSL; USOTC:CSLLY) and Arcturus Therapeutics (Nasdaq: ARCT) today announced the results of a follow-up analysis of a Phase 3 study evaluating a booster dose of ARCT-154, the world's first approved self-amplifying messenger RNA (sa-mRNA) COVID-19 vaccine, compared to a conventional mRNA COVID-19 vaccine.
- Global biotechnology leader CSL (ASX:CSL; USOTC:CSLLY) and Arcturus Therapeutics (Nasdaq: ARCT) today announced the results of a follow-up analysis of a Phase 3 study evaluating a booster dose of ARCT-154, the world's first approved self-amplifying messenger RNA (sa-mRNA) COVID-19 vaccine, compared to a conventional mRNA COVID-19 vaccine.
- ARCT-154 was administered at one-sixth the dose of Comirnaty® (5 μg vs 30 μg, respectively).
- “These results further support sa-mRNA’s differentiating attribute to provide prolonged protection against COVID-19 at lower doses,” said Jonathan Edelman, M.D., Senior Vice President, Vaccines Innovation Unit, CSL.
- GMTs against Wuhan-Hu-1 remained numerically higher 180 days after ARCT-154 than those observed 28 days after the Comirnaty® booster.
