Arcturus Therapeutics Announces Preclinical Publication of its COVID-19 Vaccine Candidate
Encouraging preclinical results demonstrate a strong antibody and cellular immune response and 100% protection against SARS-CoV-2 infection following a single vaccination
Clinical study remains on track, initial data readout expected Q4 2020
The publication: de Alwis et al., A Single Prime Self-Transcribing and Replicating RNA Based SARS-CoV-2 Vaccination Produces Protective Adaptive Immunity is available on the Bioarchive website https://www.biorxiv.org/content/10.1101/2020.09.03.280446v1
“The data we have in preprint at Bioarchive continues to provide strong support for the potent immunogenicity of LUNAR®-COV19. Results demonstrate that a single vaccination in mice led to robust antibody responses, with neutralizing antibody titers increasing up to day 60. Furthermore, activation of cell mediated immunity produced a strong viral antigen specific CD8+ T lymphocyte response and a desirable Th1 dominant immune response. Importantly, a single LUNAR®-COV19 vaccination at very low microgram doses resulted in complete protection from infection and death from SARS-CoV-2 in a transgenic human ACE2 mouse challenge model, with no detectable virus present in LUNAR®-COV19 vaccinated mice,” said Professor
“Our findings highlight the potential of LUNAR®-COV19 to be a highly potent, low dose, single shot vaccine. These favorable attributes may provide a substantial benefit compared to the multiple vaccine dosing regimens that are more commonly being developed. We believe that this advantageous profile could greatly facilitate the mass vaccination campaigns necessary to control the global COVID-19 pandemic,” said Pad Chivukula, Ph.D., CSO & COO of Arcturus.
About STARR™ Technology
The STARR™ Technology platform combines self-replicating RNA with LUNAR®, a leading nanoparticle delivery system, into a single solution to produce proteins inside the human body. The versatility of the STARR™ Technology enables it upon delivery into the cell to generate a protective immune response or drive therapeutic protein expression to potentially prevent against or treat a variety of diseases. The self-replicating RNA-based prophylactic vaccine triggers rapid and prolonged antigen expression within host cells resulting in protective immunity against infectious pathogens. This combination of the LUNAR® and STARR™ technology is expected to provide lower dose requirements due to superior immune response, sustained protein expression compared to non-self-replicating RNA-based vaccines and potentially enabling to produce vaccines more quickly and simply.
