STARR Technology Coronavirus Vaccine


Research Institution

Duke-NUS Medical School


Arcturus Therapeutics, a leading messenger RNA medicines company, and Duke-NUS Medical School (Duke-NUS), a research intensive, graduate entry medical school have announced their partnership to develop a Coronavirus (COVID-19) vaccine for Singapore. The development of a COVID-19 vaccine will be based on the Company’s STARR technology™ and will take advantage of a unique platform developed at Duke-NUS allowing rapid screening of vaccines for effectiveness and safety. The STARR Technology™ platform combines self-replicating RNA with LUNAR®, a leading nanoparticle non-viral delivery system, to produce proteins inside the human body. Due to superior immune response and sustained protein expression, Arcturus’ STARR Technology™ is expected to produce a vaccine response at much lower doses compared to traditional mRNA vaccines. This could lead to the ability to treat many more people with a single GMP-manufactured production batch, thereby greatly increasing efficiency and reducing time required to produce sufficient quantities of vaccine for large populations.

“We have observed STARR technology in pre-clinical models to be effective at extraordinarily low doses -- greater than 30-fold more efficient than traditional mRNA. The Arcturus manufacturing process has been applied in multiple large GMP batches of highly pure RNA in our LUNAR-OTC program. If successful, Arcturus could develop a vaccine capable of vaccinating millions of people for a fraction of the cost of traditional mRNA vaccines,” said Joseph Payne, President & CEO of Arcturus Therapeutics.

“Duke-NUS has been on the front lines in the fight against COVID-19, developing the first serological tests for COVID-19 and was among the first groups to isolate and culture the virus. The partnership with Arcturus Therapeutics combines complementary strengths as we work together to fight this global outbreak,” said Professor Thomas M. Coffman, Dean of Duke-NUS Medical School.
