SAN DIEGO–(BUSINESS WIRE)–$ARCT #ClinicalTrial–Arcturus Therapeutics Holdings Inc. (the “Company”, “Arcturus”, Nasdaq: ARCT), a leading clinical-stage messenger RNA medicines company focused on the development of infectious disease vaccines and significant opportunities within liver and respiratory rare diseases, today announced its financial results for the second quarter ended June 30, 2021 and provided corporate updates.
“This has been an exceptionally productive period where Arcturus has made substantial progress with our mRNA-based vaccine and therapeutic platforms. We are excited about the imminent initiation of the global Phase 3 vaccine trial of ARCT-021, which is funded by a global entity. We made excellent progress advancing and partnering ARCT-154, our next generation vaccine, which targets SARS-CoV-2 variants, including the rapidly expanding and highly transmissible Delta variant. In addition to the progress with our vaccine franchise, we’ve also advanced our therapeutics pipeline, with the approval of a multiple dose Phase 2 study with ARCT-810, our systemically administered mRNA therapeutic candidate for individuals with OTC deficiency,” said Joseph Payne, President and CEO of Arcturus.
Recent Corporate Highlights
- ARCT-021 has been selected by a global entity for inclusion in a multinational Phase 3 vaccine trial against COVID-19. The placebo-controlled study plans to enroll tens of thousands of participants and will evaluate a 5-mcg dose of ARCT-021 administered as a single injection regimen. The Phase 3 study will be sponsored and funded by the entity.
- Arcturus announced an agreement with Vinbiocare, whereby Vinbiocare will fully fund and establish a facility in Vietnam for the manufacture of Arcturus’ investigational COVID-19 vaccines. In addition to the $40 million upfront payment, Vinbiocare will purchase the mRNA drug substance from Arcturus and pay a royalty on manufactured doses.
- Arcturus has advanced ARCT-154, our next generation STARR™ mRNA vaccine candidate targeting SARS-CoV-2 variants of concern, toward multiple clinical development studies. Preclinical data demonstrate strong neutralizing immunogenicity in non-human primates to SARS-CoV-2 Alpha, Beta, Gamma, and Delta variants. ARCT-154 elicits 14.4 to 25.9-fold higher neutralizing antibody titers than ARCT-021 in non-human primates, including an observed increase of 17.8-fold higher neutralizing antibody titers against the Delta variant.
ARCT-154 utilizes an optimized STARR™ mRNA with multiple improvements, including modifications for stability and translation, increased immunogenicity of the spike protein antigen via amino acid substitution, expressing the spike protein in a pre-fusion state, and inactivating the furin cleavage site.

Non-Human Primate (NHP) data collected one month after second dose of 7.5 mcg; analysis of NHP serum was performed using non-replicating vesicular stomatitis virus pseudo-typed with the spike protein of the SARS-CoV-2 variants of concern indicated. Titers (geometric mean) were determined by calculating the dilution that resulted in 50% inhibition of cells expressing GFP encoded by the pseudovirus, a surrogate of virus infection. Error bars indicate geometric standard deviation. |
|||||
T cell responses for ARCT-021 and ARCT-154 are robust and similar in non-human primates. Notably, STARR™ mRNA vaccines elicit similar T cell responses against all variants of concern tested. The robust T cell responses are attributed to the self-amplifying mRNA mechanism of antigen expression.
- Arcturus announced approval of a Clinical Trial Application (CTA) from the Singapore Health Sciences Authority (HSA) enabling the advancement of ARCT-154 into a Phase 1/2 clinical trial to evaluate the vaccine as a primary vaccination series and as a booster following initial vaccination with Comirnaty® (marketed by Pfizer and BioNTech). The Phase 1/2 trial costs are funded in part from a previously secured grant from Singapore.
- Arcturus announced that the company’s partner Vinbiocare received approval for a CTA from the Vietnam Ministry of Health to advance ARCT-154 into a Phase 1/2/3 clinical study. The trial is a randomized, observer-blind, placebo-controlled design, and is sponsored and completely funded by Vinbiocare. The Phase 1/2/3 study will assess the safety, immunogenicity and efficacy in up to 21,000 adults, with potential Emergency Use Authorization (EUA) by the Vietnam Ministry of Health in December 2021.
- Arcturus announced approval from the UK Health Research Authority to initiate a multiple dose Phase 2 clinical study for ARCT-810, a novel mRNA-based therapeutic candidate for Ornithine Transcarbamylase (OTC) Deficiency. The ARCT-810 Phase 2 study is a randomized, double-blind, placebo-controlled, nested single and multiple ascending dose design for adolescents and adults with OTC deficiency. ARCT-810 Phase 2 study interim results in a subset of participants are expected in H2 2022.
Financial Results for the Quarter Ended June 30, 2021
Revenues in conjunction with strategic alliances and collaborations: Arcturus’ primary sources of revenues were from license fees and collaborative payments received from research and development arrangements with pharmaceutical and biotechnology partners. For the three months ended June 30, 2021, the Company reported revenue of $2.0 million compared with $2.3 million for the three months ended June 30, 2020.
Operating expenses: Total operating expenses for the three months ended June 30, 2021, were $55.7 million compared with $12.4 million for the three months ended June 30, 2020 and $59.8 million for the three months ended March 31, 2021.
Research and development expenses increased by approximately $37.7 million year over year in the second quarter ended June 30, 2021 due to increased personnel costs as well as expenses related to our ARCT-810 and ARCT-021 programs. Research and development declined by approximately $5 million sequentially in the June 2021 quarter due primarily to the one-time $5 million exclusive license cost from Alexion Pharmaceuticals in the first quarter of 2021.
For the three months ended June 30, 2021, Arcturus reported a net loss of approximately $54.6 million, or ($2.07) per basic and diluted share, compared with a net loss of $10.3 million, or ($0.55) per basic and diluted share in the three months ended June 30, 2020.
The Company’s cash balance totaled $433.6 million as of June 30, 2021, compared to a cash balance of $462.9 million at December 31, 2020. Subsequent to the end of the quarter, the company received the remaining $30 million of our upfront payment from Vinbiocare. Based on our current pipeline, the Company’s cash position is expected to be sufficient to support operations for more than two years.
