ExpreS2ion’s joint venture, AdaptVac, receives notice of allowance in the U.S. for its breast cancer vaccine patent

ExpreS2ion Biotech Holding AB and its affiliate ExpreS2ion Biotechnologies ApS (“ExpreS2ion") announce that its joint venture AdaptVac has received a notice of allowance in the USA for its patent application covering its novel vaccine treatment for HER2-positive breast cancer. This means that the patent is expected to be issued shortly, which is an important step forward for the project and documenting the patentability of the virus-like-particle (VLP) technology platform. After final approval, the patent will be valid at least 20 years from the priority date, 15-01-2015.

This is a major milestone for AdaptVac, and in particular strengthens the company’s position in negotiations with potential development partners for the AV001 breast cancer project. It furthermore adds credibility in general to the platform and any additional projects from AdaptVac’s project portfolio,” says ExpreS2ion’s CEO Dr. Steen Klysner.

AdaptVac has filed patent applications for its HER2 breast cancer vaccine in all major and upcoming commercially relevant markets, including the USA and Europe. The divisional patent application that was allowed by the U.S. patent office is titled “Virus-like particle with efficient epitope display".
