CSL and Arcturus Therapeutics announced pivotal data published in Nature Communications demonstrating the efficacy and tolerability of their novel self-amplifying (sa-mRNA) COVID-19 vaccine, ARCT-154. The vaccine, the first of its kind approved in Japan, showed 100% efficacy against severe COVID-19 in healthy adults aged 18-59 and over 90% efficacy in older adults or those with comorbidities. The study, covering phases 1 through 3b, indicated that two 5 μg doses were well-tolerated and provided robust protection against multiple strains, including Omicron BA 4/5. The results underline the potential of the sa-mRNA technology to offer long-lasting immunity and superior protection compared to traditional mRNA vaccines.

CSL and Arcturus Therapeutics announced that Nature Communications published results from an integrated phase 1/2/3a/3b study on ARCT-154, a self-amplifying mRNA COVID-19 vaccine.
