“Arcturus continues to demonstrate increasing value of our next generation mRNA vaccine and therapeutic platforms,” said Joseph Payne, President and CEO of Arcturus Therapeutics. “Additional data from our Phase 1/2 booster study demonstrates that ARCT-154 provides sustained neutralizing antibodies against Omicron variants BA.1/BA.2 three months after booster vaccination. We are further pleased to share new data demonstrating the stability of our lyophilized vaccines under a broad range of transportation and storage conditions. Our work on the LUNAR-OTC program has been acknowledged with Orphan Medicinal Product Designation issued by the European Commission, which is promising news for the continued development of ARCT-810 for OTC deficient patients.”

Recent Corporate Highlights

  • Arcturus shared additional data from the ARCT-154 arm of its ongoing Phase 1/2 study in the U.S., Singapore, and South Africa evaluating a single 5-mcg booster dose of ARCT-154 given at least five months following two primary doses of Comirnaty®. In exploratory microneutralization titer (MNT) assays, ARCT-154 demonstrates a robust neutralizing antibody response against the Omicron BA.1 and BA.2 variants up to 91 days after administration. Against BA.1 the Geometric Mean Fold Rise (GMFR) was 44-fold at Day 91 compared to 54-fold at Day 29. Against BA.2 the GMFR was 39-fold at Day 91 compared to 47-fold at Day 29 (Figure 1). Six-month data for Omicron variants, including BA.5, is being collected and will be shared this quarter.
  • New stability data supports the advantages of using a lyophilized vaccine powder to mitigate the cold chain challenges associated with frozen liquid mRNA vaccines. Our lyophilized COVID vaccine powder demonstrated room temperature stability (25°C RT; 60% RH) for 4 days, refrigerator stability (2-8°C) for 6 months, and a predicted long-term stability (-25°C to -15°C) for 18 months. Importantly, the lyophilized powder was not impacted by multiple temperature cycling stress (-20°C to 2-8°C or RT) enabling global shipping logistics and supply of a stable usable solid COVID vaccine product at 2-8°C.
  • ARCT-810 Orphan Medicinal Product Designation: Arcturus was notified by the European Commission that ARCT-810 has been designated as an Orphan Medicinal Product for the treatment of OTC deficiency. The designation provides significant incentives to promote the development of the drug including protocol assistance, access to the centralized authorization procedure, fee reductions, and research grants, as well as 10 years of market exclusivity.
  • ARCT-810, the Company’s mRNA therapeutic candidate for OTC deficiency will be evaluated in a randomized, double-blind, placebo-controlled, nested single and multiple ascending dose Phase 2 study in 24 adolescents and adults with OTC deficiency. Participating sites have identified several dozen patients in pre-screening, with the goal of obtaining interim proof-of-concept data by year end.
  • Due to additional non-clinical data requirements, ARCT-032 (the Company’s inhaled mRNA therapeutic candidate for cystic fibrosis) is now expected to file for a Clinical Trial Application in Q4 2022.
  • The Vinbiocare manufacturing facility in Hanoi, Vietnam, is anticipated to achieve commercial scale production capability in Q4 2022.
  • The Vietnam Ministry of Health (MOH) is undergoing a significant reorganization resulting in a delay of the ARCT-154 Emergency Use Authorization (EUA) for the primary series. During the reorganization, the MOH communicated that the Clinical section review is complete and adequate. The MOH provided comments to the Chemistry, Manufacturing, and Controls (CMC) section, requesting three manufacturing runs to support full Market Authorization. ARCT-154 is now expected to receive EUA in Q4 2022, with full Marketing Authorization anticipated in early 2023 if booster studies meet noninferior immunogenicity and safety objectives.
  • Arcturus expects a registrational booster study for ARCT-154 to begin in Q4 2022. Based on recent health authority guidance, the Company is considering an updated design consisting of two trials to support global registration of ARCT-154 as a booster.

Financial Results for Second Quarter Ended June 30, 2022

Revenues in conjunction with strategic alliances and collaborations: Arcturus’ primary sources of revenues were from consulting and related technology transfer fees, reservation fees, license fees and collaborative payments received from research and development arrangements with pharmaceutical and biotechnology partners. For the three months ended June 30, 2022, the Company reported revenue of $27.1 million compared with $2.0 million for the three months ended June 30, 2021, and $5.2 million for the three months ended March 31, 2022. The increase in revenue during the three months ended June 30, 2022, as compared to the three months ended March 31, 2022, and June 30, 2021, was primarily due to revenue of $12.5 million related to the one-time recognition of reservation fees from the Israel MOH and an increase in revenue from Vinbiocare related to shipments of drug substance to validate their manufacturing facility.

Operating expenses: Total operating expenses for the three months ended June 30, 2022, were $49.2 million compared with $55.7 million for the three months ended June 30, 2021, and $55.7 million for the three months ended March 31, 2022. The decline in operating expenses during the three months ended June 30, 2022, as compared to the three months ended March 31, 2022 was due primarily to a decrease in clinical trial expenses related to ARCT-154.

Research and development expenses: Research and development expenses for the three months ended June 30, 2022, were $38.2 million compared with $45.7 million for the three months ended June 30, 2021, and $44.9 million for the three months ended March 31, 2022. The decline in operating expenses during the three months ended June 30, 2022, as compared to the three months ended March 31, 2022, and June 30, 2021, was due primarily to a decrease in clinical trial expenses.

Net Loss: For the three months ended June 30, 2022, Arcturus reported a net loss of approximately $21.6 million, or ($0.82) per basic and diluted share, compared with a net loss of $54.6 million, or ($2.07) per basic and diluted share in the three months ended June 30, 2021, and a net loss of $51.2 million, or ($1.94) per basic and diluted share in the three months ended March 31, 2022.

Cash Position: The Company’s cash balance totaled $283.5 million as of June 30, 2022, compared to a cash balance of $370.5 million at December 31, 2021. Based on the current pipeline, the Company’s cash position is expected to be sufficient to support operations into late 2023.
