Arcturus Therapeutics is an RNA medicines company developing vaccines and therapies for infectious, liver, and respiratory rare diseases, with multiple programs and collaborations worldwide.

KOSTAIVE® is the first approved self-amplifying mRNA COVID-19 vaccine, licensed in Japan and the EU, showcasing Arcturus's sa-mRNA platform with potential for broader, durable infectious disease protection.
Arcturus Therapeutics announced in its Q3 2025 financial update the indefinite delay of the U.S. Biologics License Application (BLA) for its COVID-19 vaccine, KOSTAIVE®, due to sudden changes in FDA regulatory requirements. This significant regulatory setback for a key commercial product prompted the company to implement additional cost-reduction measures to extend its cash runway and pivot focus towards its cystic fibrosis and OTC deficiency programs.
In 2025, Arcturus Therapeutics made a significant strategic decision to deprioritize its early-stage vaccine programs for chlamydia, gonorrhea, and Lyme disease. This move was part of a broader portfolio rationalization to intensify focus and reallocate resources to its core mRNA therapeutic candidates for rare diseases, specifically ARCT-032 for cystic fibrosis and ARCT-810 for ornithine transcarbamylase (OTC) deficiency.
