ARCT-021 single-shot COVID-19 STARR™ mRNA vaccine to be advanced to Phase 3 clinical development – on track to initiate Phase 3 study in Q2
ARCT-021 single shot immunogenicity profile compares favorably with new data generated from recipients of a single dose of an approved conventional mRNA vaccine
ARCT-810 mRNA therapeutic for ornithine transcarbamylase deficiency to be advanced to Phase 2 clinical development – on track to file CTA for Phase 2 multiple dose study in Q2
ARCT-032 mRNA therapeutic for cystic fibrosis: completed successful pre-IND interaction with FDA – on track to file CTA in Q4
Investor conference call at 4:30 p.m. ET today
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 quarter and full year ended December 31, 2020 and provided a corporate update.
"Based on highly promising clinical data from our Phase 1/2 study and emerging mRNA vaccine immunological data, we are advancing ARCT-021 for further development in Phase 3. We are presently preparing to move forward a 5 µg single dose regimen, to be confirmed based on pending Phase 2 data. Our self-amplifying mRNA-based investigational vaccine may provide a differentiated clinical profile and characteristics that support widespread distribution across the globe. Our expectation is that successful protection from COVID-19 will require repeated vaccination of billions of individuals for years to come and that ARCT-021 will be re-dosable. We believe that a re-dosable, more easily distributable single shot mRNA vaccine would be a valuable option for many countries," said Joseph Payne, President and CEO of Arcturus.
"In addition to advancing our vaccine franchise, we have made continued progress advancing our pipeline of promising liver and lung mRNA therapeutic candidates. After successfully beginning enrollment in the U.S. for our Phase 1b study for ARCT-810, a therapeutic candidate for Ornithine Transcarbamylase (OTC) Deficiency, we have now also received approval from Health Canada to enroll subjects. We look forward to obtaining clinical data this year," concluded Mr. Payne.
Recent Corporate Highlights
ARCT-021, Vaccine Candidate for SARS-CoV-2
1) Ongoing Phase 2 clinical study and planning for Phase 3 development:
More than 500 participants dosed across USA and Singapore
Phase 3 study initiation remains on track for Q2
Targeting application for Emergency Use Authorization in one or more jurisdictions in H2 2021
2) Encouraging new supportive data from Duke-NUS Medical School submitted for publication:
Dr. Eng Eong Ooi, Professor of Emerging Infectious Diseases at Duke-NUS Medical School, and colleagues, examined the adaptive immune responses of an approved conventional mRNA vaccine after a single administration
Data suggest that binding antibodies and cellular immunity are associated with COVID-19 protection at early timepoints after the first injection
ARCT-021 single shot immunogenicity profile in Phase 1/2 study compares favorably, providing additional support for the potential efficacy of the ARCT-021 vaccine
IgG (≥ 4-fold rises)
PRNT (% Detectable)
*Increases to 100% by Day 36
IgG = Immunoglobulin G binding antibodies to full length spike protein
PRNT = plaque reduction neutralization test
SFUs = Spot Forming Units per million peripheral blood mononuclear cells
3) Completed Phase 1/2 clinical study and supporting preclinical studies:
Phase 1/2 study is complete and final data are under analysis; plan to submit results for publication in Q2
ARCT-021 demonstrated robust protection with single dose in a primate challenge model and in a human ACE2 receptor transgenic mouse challenge model
ARCT-021 demonstrated robust protection with a single dose in mice depleted of B cells, whereas depletion of T lymphocytes yielded no protection following virus challenge, emphasizing the importance of ARCT-021 induced cellular immunity
Recently received $46.6M from Singapore EDB to support ARCT-021 stockpiling
Manufacturing of lyophilized ARCT-021 to support Phase 3 and initial commercial supply well on track
Stability studies for lyophilized ARCT-021 at -20°C, 2-8°C and room temperature storage conditions ongoing

The technology supports Arcturus’ highly efficient processes to manufacture high purity mRNA vaccine and therapeutic candidates at kilogram scale
Extends the substantial intellectual property portfolio held by Arcturus
Financial results for the quarter and full year ended December 31, 2020
Revenues in conjunction with strategic alliances and collaborations: Arcturus’ primary source of revenues is from license fees and collaboration payments received from research and development arrangements with our pharmaceutical and biotechnology partners.
On a quarterly basis, total revenue for the three months ended December 31, 2020 was $2.2 million and was relatively flat when compared to the $2.3 million of the quarter ended September 30, 2020.
On a yearly basis, reported revenues of $9.5 million during the year ended December 31, 2020, decreased from $20.8 million in the year ended December 31, 2019. The decline in collaboration revenues primarily relates to three factors: a $5.6 million decrease in reimbursements from CureVac associated with the OTC collaboration that ended in the third quarter of 2019, a decrease in one-time license revenue of $3.3 million from Synthetic Genomics that occurred in 2019, and lower activity with other collaboration partners.
Operating expenses: On a quarterly basis, total operating expenses for the three months ended December 31, 2020 were $33.3 million compared with $23.3 million for quarter ended September 30, 2020, and $13.8 million in same period of 2019. Approximately $8 million of the sequential increase in operating expenses during the quarter ended December 31, 2020 was due to the ramp in the Covid-19 program related expenses, which included additional personnel, manufacturing and clinical trial expenses. The current quarter operating expenses were partially offset by $2.7 million in funds awarded under the Singapore vaccine grants and by the Cystic Fibrosis Foundation.
On a yearly basis, total operating expenses were $81.1 million for the year-ended December 31, 2020 compared with $46.3 million for the year ended December 31, 2019. The current year operating expenses were partially offset by $15.2 million of funds earned under the Singapore vaccine grants and funds awarded by the Cystic Fibrosis Foundation. The increase in net expenditures for the year ended December 31, 2020 as compared to the prior year was due primarily to the increased activity in clinical and manufacturing expenditures related to the Company’s Covid-19 and OTC programs as well as increased personnel costs and other facility costs related to the organizational growth of the Company.
Net loss: For the three months ended December 31, 2020 Arcturus reported a net loss of approximately $31.1 million, or ($1.25) per basic and diluted share, compared with a net loss in the three months ended September 30, 2020 of $21.0 million, or ($0.92) per basic and diluted share, and three months ended December 31, 2019 of $11.0 million, or ($0.76) per basic and diluted share.
For the year ended December 31, 2020, net loss was approximately $72.1 million, or ($3.55) per basic and diluted share, compared with a net loss for the year ended 2019 of $26.0 million, or ($2.15) per basic and diluted share.
Cash and Cash Equivalents: The Company’s cash balance was $463.0 million as of December 31, 2020, compared to cash and cash equivalents of $301.1 million on September 30, 2020. The increase in cash and cash equivalents compared to the prior year is primarily due to the receipt of approximately $162 million in net proceeds from our December 2020 public offering. Subsequent to the end of the quarter, in January 2021 the Company received $46.6 million in funds under a manufacturing loan from Singapore EDB for our Covid-19 vaccine program. Based on our current pipeline, the Company’s cash position is expected to be sufficient to support operations for more than two years.
