ANN ARBOR, Mich. & TAIPEI, Taiwan

BlueWillow Biologics, Inc., a pioneer in intranasal vaccine development, and Medigen Vaccine Biologics Corporation (MVC) (TPEx: 6547.TWO), a biopharmaceutical company focusing on the development and production of vaccines and biologics, today announced that its intranasal COVID-19 booster (BW-1019) provided protection and boosted immune response when administered following an intramuscular vaccine series in preclinical studies.

The study examined the responses in hamsters receiving various regimens of intramuscular-only, intramuscular primary and intranasal booster vaccine, and negative control group receiving no vaccination. The results, which have been published on the preprint server bioRxiv, showed that the groups receiving the intranasal booster had significant induction of virus neutralizing antibodies and showed protection against COVID-19 disease. In addition, all animals boosted intranasally with BW-1019, except that of the dose sparing group, had no detectable virus in their lungs and nasal passages.

“COVID-19 has proven the importance of eliciting mucosal immunity through intranasal vaccination in order to stop the cycle of upper respiratory viral carriage and spread,” said Vira Bitko, PhD, Vice President of Vaccine R&D at BlueWillow Biologics. “We are excited to demonstrate that our intranasal vaccine candidate not only provides mucosal protection but also boosts the systemic immunity elicited from intramuscular vaccination against COVID-19. We have previously shown similar results in other diseases.”

The intranasal COVID-19 booster combines BlueWillow’s proprietary nanoemulsion technology, which acts as both an efficient antigen delivery and adjuvant, with Medigen’s U.S. National Institutes of Health-licensed SARS-CoV-2 spike protein. BlueWillow’s technology platform enables its robust pipeline of vaccine candidates, which includes programs directed at HSV-2, RSV, influenza, Anthrax and food immunotherapy. The company recently announced positive interim data from a Phase 1 clinical trial in Anthrax. The platform is unique among intranasal solutions in that it does not rely on an adenovirus vector but rather utilizes the adjuvant that is proven to be safe in humans.

Charles Chen, Chief Executive Officer of Medigen, commented, “We are pleased that the jointly developed intranasal vaccine has shown strong results in this preclinical study. We are very excited to see the promising boosting effect, which may be an ideal COVID-19 vaccine candidate and complimentary to intramuscular vaccinations. We hope that it will significantly assist in preventing viral transmission of COVID-19.”

“We look forward to rapidly advancing this intranasal COVID-19 booster into clinical trials,” added Chad Costley, MD, Chief Executive Officer of BlueWillow. “The current intramuscular vaccines have saved millions of lives, but the limited durability of immune response and lack of sufficient mucosal immunity from these vaccines is now evident. In addition, to properly scale worldwide vaccination, boosters need to be less expensive and more easily administered. BlueWillow’s nanoemulsion adjuvant and Medigen’s spike protein have both already been proven safe in humans, which enables our COVID-19 vaccine candidate to rapidly advance into clinical trials.”
