COVID-19 Vaccine Program
In March, Arcturus, along with partners CSL (search) and Meiji, announced that ARCT-2301, its bivalent COVID-19 (search) vaccine candidate, met the primary endpoint (non-inferiority) in a Phase 3 clinical study in Japan. The study involved 930 healthy adults and individuals with comorbidities who had previously received three to five doses of mRNA COVID-19 vaccines. The results showed that ARCT-2301 demonstrated non-inferiority and superiority criteria versus a licensed mRNA vaccine comparator.
Financial Overview
For the three months ended March 31, 2024, Arcturus reported revenues of $38.0 million, compared to $80.3 million for the same period in 2023. The decrease was primarily due to the timing of revenue recognition from the CSL (search) agreement. Research and development expenses were $53.6 million, driven by the CSL and BARDA programs, as well as internal OTC and Cystic Fibrosis (search) programs. The company reported a net loss of $26.8 million, or ($1.00) per diluted share. As of March 31, 2024, cash, cash equivalents, and restricted cash totaled $345.3 million, providing a cash runway extending to the first quarter of fiscal year 2027.
Pipeline Expansion
Arcturus is also progressing ARCT-2138 (LUNAR-FLU), a quadrivalent seasonal influenza (search) vaccine, through its partner CSL (search). A Phase 1 dose-finding and immunogenicity study is ongoing, with 84 healthy young adults recruited as of May 1, 2024. Recruitment of older adults is also underway. Additionally, Arcturus has engaged JP Morgan to monetize its investment in ARCALIS JV in Japan.
