Arcturus Therapeutics Presents New Clinical Data at 47th Annual European Cystic Fibrosis Conference

ARCT-032 is safe and well tolerated with no serious adverse events (SAEs) in 36 study participants, including 4 adults with cystic fibrosis (CF)

Phase 1b interim data includes a CF participant with Class 1 mutations and three participants with F508del mutations being treated with Trikafta®

Early trend of improved lung function with an average absolute response of +4.0% (ranging up to +9%) and relative change of +5.8% FEV1 on Day 8, after two doses of ARCT-032

Clinical data is consistent with pre-clinical CF ferret model data

Arcturus Therapeutics Holdings Inc. (the “Company”, “Arcturus”, Nasdaq: ARCT), a global messenger RNA medicines company focused on the development of infectious disease vaccines and medicines to treat unmet medical needs within liver and respiratory rare diseases, today presented Phase 1 results in healthy volunteers and Phase 1b interim data in people with CF for ARCT-032, an inhaled investigational mRNA therapeutic, at the 47th European Cystic Fibrosis Conference in Glasgow, Scotland.

ARCT-032 administration was generally safe and well tolerated with no serious or severe adverse events in healthy volunteers and the first four dosed participants with CF. The Phase 1b trial showed improvements in FEV1 (Forced Expiratory Volume in 1 second) in the four adults with CF after two inhaled administrations. The absolute change in percent predicted FEV1 averaged +4.0% on Day 8 (5 days after 2nd dose). The relative change in FEV1 averaged +5.8% on Day 8. The observed increases in FEV1 are encouraging and consistent with the previously reported data in the CF ferret model that demonstrated markedly improved mucociliary clearance (MCC) after a single dose of ARCT-032. Of the four participants in Phase 1b to date, one had 2 Class I mutations and the other three had F508del mutations and were being treated with Trikafta®.

No bronchospasm or febrile reactions were observed in the CF participants. Dose-related, mild-to-moderate febrile reactions (elevated temperature associated with headache, muscle aches, back pain, or nausea) occurred in some healthy volunteers. Dose-related transient declines in FEV1 observed in healthy volunteers were mitigated by pretreatment with albuterol, a commonly used bronchodilator. No serious adverse events or dose limiting toxicities were observed at any dose level.

“We are pleased to present positive ARCT-032 Phase 1 results and Phase 1b interim data showing that single doses at all dose levels in healthy volunteers and two doses in the first four CF participants were safe and well tolerated with no serious adverse events. It is encouraging to see favorable lung function improvements in all currently dosed CF participants in this early study,” said Dr. Juergen Froehlich, Chief Medical Officer of Arcturus Therapeutics. “We look forward to completing the Phase 1b trial shortly and to evaluate the further potential for lung function improvement of treatment with ARCT-032 in people with CF in a larger, multiple-dose clinical study.”

About Cystic Fibrosis

Cystic fibrosis is a life-shortening disease with a worldwide distribution. Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene result in a reduction or absence of CFTR protein and/or function in the airways, causing insufficient chloride transport to maintain airway surface homeostasis. CF mucus is more difficult to clear, thus clogging the airways and leading to infection, inflammation, respiratory failure, or other life-threatening complications. Currently approved CFTR modulator therapies are designed to increase function of the CFTR channel to help reduce symptoms yet are ineffective in some people with CF because of their underlying mutations.

About ARCT-032

ARCT-032 has received Orphan Medicinal Product Designation from the European Medicines Agency (EMA) and Orphan Drug Designation from the U.S. Food and Drug Administration (FDA) to treat Cystic Fibrosis. ARCT-032 utilizes Arcturus' LUNAR® lipid-mediated aerosolized platform to deliver CFTR messenger RNA to the lungs. Expression of a functional copy of the CFTR mRNA in the lungs of people with CF has the potential to restore CFTR activity and mitigate the downstream effects that cause progressive lung disease. The ARCT-032 program is supported by preclinical data in rodents, ferrets and primates, as well as demonstrating restoration of CFTR expression and function in human bronchial epithelial cells.
