Arcturus Therapeutics Holdings Inc.

Previous wording

We are a messenger RNA medicines company focused on the development of infectious disease vaccines and opportunities within liver and respiratory rare diseases. We developed the world’s first approved self-amplifying messenger RNA (sa-mRNA) vaccine, KOSTAIVE® (“KOSTAIVE”). KOSTAIVE achieved approval in Japan in 2023 as a vaccine against COVID-19. Sales of KOSTAIVE began in Japan in October 2024, marking our transition to a commercial stage company.

Current wording

We developed the world’s first approved self-amplifying messenger RNA (sa-mRNA) vaccine, KOSTAIVE® (“KOSTAIVE”), which we have partnered with Seqirus, Inc. (“CSL Seqirus”), a part of CSL Limited. KOSTAIVE has achieved approval in Japan, the European Union and the United Kingdom as a vaccine against COVID-19, and sales of KOSTAIVE began in Japan in October 2024.

Previous wording

We have several key platform technologies that we leverage to develop and advance a pipeline of mRNA-based vaccines and therapeutics for infectious diseases and for rare genetic disorders with significant unmet medical needs. Current mRNA medicines have two critical components: the messenger RNA (“mRNA”) constructs and the lipid nanoparticles (“LNP”) which help deliver the mRNA to disease-relevant target tissues. We believe we are among the world leaders in both areas. We have extensive expertise in the design and optimization of mRNA constructs, including with respect to a type of mRNA technology known as self-amplifying mRNA (sa-mRNA). Our proprietary self-amplifying mRNA technology platform, or STARR® (“STARR”), has been demonstrated to induce a longer-lasting and broader humoral immune response at lower dose levels than conventional mRNA-based vaccines. Our proprietary LNP delivery system, LUNAR® (“LUNAR”), is intended to address the major hurdle in RNA drug development, namely the effective and safe delivery of RNA therapeutics to disease-relevant target tissues. LUNAR may enable multiple nucleic acid medicines. The approval of KOSTAIVE in Japan was a significant milestone which validates our LUNAR and STARR platforms, as well as sa-mRNA more generally as a meaningful modality. Finally, we have significant expertise and valuable know-how in the development and scalability of complex and robust manufacturing processes required to deliver the next generation of nucleic acid medicines.

Current wording

Our internal pipeline includes RNA therapeutic candidates to potentially treat ornithine transcarbamylase (OTC) deficiency and cystic fibrosis (CF), both rare diseases. In our vaccine program, we have partnered with CSL Seqirus, one of the world’s leading influenza vaccine providers, on the development and commercialization of mRNA vaccines for COVID-19, influenza and three other infectious diseases. In CSL Limited’s half-year results presented on February 11, 2026, CSL Limited reported an accounting write-down of approximately $430 million attributable to our collaboration agreement with CSL Seqirus, citing declining COVID-19 disease burden and more onerous U.S. regulatory requirements.

Previous wording

In our CF program, we initiated dosing in December 2024 in a Phase 2 multiple ascending dose study of ARCT-032 designed to identify a safe and effective dose in people with Class I (null) CFTR mutations and other CF patients who do not benefit from CFTR modulators. In July 2024, we completed dosing and follow-up visits for seven participants in a safety and tolerability Phase 1b clinical study in New Zealand of ARCT-032 in adults with CF. ARCT-032 has received Orphan Drug Designation by the FDA and Orphan Medicinal Product Designation by the EMA for the treatment of CF, and Rare Pediatric Disease Designation from the FDA.

Current wording

In our CF program, we enrolled and completed dosing in the three initially planned cohorts of our Phase 2 multiple ascending dose study of ARCT-032, confirming the safety and tolerability of ARCT-032 dosed daily for four weeks. This study was initiated in December 2024 and was designed to identify a safe and effective dose regimen in those with Class I (null) CFTR mutations and people with CF who do not benefit from CFTR modulators. In the study, six CF adults with Class I CFTR mutations inhaled 10 mg doses of ARCT-032 daily over 28 days. Interim results released in October 2025 demonstrated that the treatment was generally safe and well tolerated. Treatment-related adverse events (AEs) that were identified in the single-dose Phase 1 study were also observed in some participants for the first few doses but ceased with continued dosing. Bronchospasm has not been reported in this study thus far, neither with nor without albuterol pretreatment. One serious adverse event (SAE) occurred in a participant after the end of the dosing period. The safety review committee found no convincing evidence that the SAE is related to ARCT-032 and approved the study to proceed. We intend to initiate a 12-week safety and preliminary efficacy study in up to 20 CF participants in the first half of 2026, after the third cohort completes treatment. ARCT-032 has received Orphan Drug Designation by the U.S. Food and Drug Administration (the “FDA”) and Orphan Medicinal Product Designation by the European Medicines Agency (the “EMA”) for the treatment of CF, and Rare Pediatric Disease Designation from the FDA.

Previous wording

In our OTC program, we completed dosing of eight subjects in August 2024 in a Phase 2 double-blind multiple-dose study of ARCT-810. In the second quarter of 2024, we expanded the Phase 2 clinical program of ARCT-810 with an open-label, multiple-dose study which initiated dosing in December 2024. ARCT-810 has received Orphan Drug Designation from the FDA and Orphan Medicinal Product Designation from the European Medicines Agency (the “EMA”) for treatment of OTC deficiency, as well as Fast Track Designation and Rare Pediatric Disease Designation from the FDA.

Current wording

In our OTC program, we have continued to conduct a Phase 2 double-blind multiple-dose study of ARCT-810. Five patients with OTC deficiency have now completed dosing, and a sixth patient has initiated dosing. A type C meeting with the FDA to discuss our plans for a proposed future pediatric study under the RDEP (Rare Disease Evidence Principles) is scheduled for the first half of 2026. ARCT-810 has received Orphan Drug Designation from the FDA and Orphan Medicinal Product Designation from the EMA for treatment of OTC deficiency, as well as Fast Track Designation and Rare Pediatric Disease Designation from the FDA.
