Building of the Innovative Platform for Vaccine Formulation

Initiation of Phase I Clinical Trial for Seasonal Influenza HA Vaccine Sublingual Tablet

Nitto Denko Corporation (Headquarters: Osaka; President, CEO&COO: Hideo Takasaki; “Nitto”, hereafter) initiated phase I clinical trials to sublingually administer a seasonal influenza HA vaccine tablet (code: NSV0001), a joint development with the Research Foundation for Microbial Diseases of Osaka University (Head Office: Suita city, Osaka; Director General: Koichi Yamanishi) on October 2016 in Japan.
Nitto’s tablet-type influenza vaccine is administered under the tongue and can induce specific antibodies on mucosal surfaces using an innovative platform containing a novel adjuvant. So this vaccine can not only deactivate infected viruses in human body, but also potentially prevent viruses themselves from infecting human body.
Nitto has been developing a tablet-type vaccination since 2009 in collaboration with Prof. Shizuo Akira of the WPI Immunology Frontier Center in Osaka University.
Nitto also aims for practical realization of this influenza vaccine as a first step and plans to expand this platform to other vaccines in the future.
Characteristics of the NSV0001 seasonal influenza vaccine tablet:
  • Potentially protect against infection and illness caused by the viruses
  • Painless administration (needle-free vaccination)
  • Possibly store at ambient temperature
Seasonal influenza HA vaccine: Commercialized influenza vaccine in Japan
Platform: Sublingual vaccine formulation containing the novel adjuvant
Adjuvant: Compound to enhance immune response
