Research indicates that intranasal administration is effective at stimulating the mucosal immunity response. Preclinical study shows positive serum and mucosal immune response.
Tapei, Taiwan & ANN ARBOR, Michigan, November 10, 2020 – Medigen Vaccine Biologics Corporation (MVC) (TPEx: 6547.TWO), a biopharmaceutical company focusing on the development and production of vaccines and biologics, and BlueWillow Biologics, Inc., a privately held clinical-stage biopharmaceutical company developing intranasal vaccines through its patented NanoVax™ adjuvant, today announced a partnership to develop S-2P-NE-01, a nasal vaccine for SARS-CoV-2, the virus that causes COVID-19.
While the majority of COVID-19 vaccines in development today are delivered via intramuscular injection, research has demonstrated that nasal delivery – often the initial site of the infection – can prevent the virus from taking hold in the body. Preclinical research demonstrated that BlueWillow’s nasal vaccine adjuvant combined with Medigen’s S-2P spike protein resulted in an extremely high neutralizing antibody response, as well as a superior immunoglobulin A (IgA) response in both serum and lung secretions (BAL) samples in mice compared to intramuscular injection of S-2P adjuvanted with alum. Mucosal immune response is critical in reducing viral nasal colonization and preventing the spread of SARS-CoV-2.
“Our partnership with MVC is a tremendous milestone in our plan to develop a nasal vaccine for SARS-CoV-2 and we are buoyed by the preclinical results showing that intranasal vaccination with S-2P-NE-01 holds great promise for both mucosal and serologic immunity to SARS-CoV-2,” said Chad Costley, MD, CEO of BlueWillow Biologics. “Our plan is to rapidly advance S-2P-NE-01 into human clinical trials as we move forward to battle this global pandemic.”
“As the COVID-19 pandemic continues to spread around the world, there is an urgent need to develop a vaccine to fight this global crisis and we are proud to partner with BlueWillow to create an intranasal vaccination that has the potential to save human lives,” said Charles Chen, CEO of MVC. “While there has been a lot of movement in the development of vaccines, research continues to show the vast benefits of an intranasal vaccination and we look forward to the ongoing clinical development of our product candidate.”
BlueWillow NanoVax Adjuvant Technology
BlueWillow’s vaccine technology utilizes a novel oil-in-water nanoemulsion (NE) adjuvant to enable intranasal vaccines for challenging diseases and intranasal immunotherapy (INIT) for food allergies. The adjuvant includes soybean oil, water and a cationic surfactant cetylpirdinium chloride (CPC) and is currently in use in the company’s clinical-stage anthrax and pandemic flu programs and National Institutes of Health (NIH)-funded preclinical stage RSV, HSV and peanut immunotherapy programs. When used with intranasal vaccination, the NE adjuvant elicits both mucosal and systemic immunity.
MVC S-2P Spike Protein
MVC’s subunit vaccine is based on the stable prefusion form of the SARS-CoV-2 recombinant spike protein with global technology license from the U.S. Vaccine Research Center at the National Institutes of Health (NIH).
