Vaxon Biotech, a company specialized in anti-tumor immunotherapy, has been granted a new patent in Japan. This patent (JP application no. 2012-502822) covers a series of optimized cryptic peptides to be used in the design of the Vbx-026, a new cancer vaccine for solid tumors.
This patent gives Vaxon exclusive rights in Japan and raises its worldwide portfolio to 24 issued patents.
The patent will support the development of Vbx-026, a vaccine dedicated to the treatment of cancer patients expressing the HLA-A24 molecule. This molecule is widely expressed in the Asian population, mainly in Japan, with more than 40% of the Japanese population expressing HLA-A24. The initiation of preclinical development of the Vbx-026 vaccine is planned for 2016.
"This new patent will strengthen our position in Japan, a promising market for the development of the Vbx-026 vaccine," said Dr. Kostas Kosmatopoulos, CEO of Vaxon Biotech. "With four cancer vaccines under development, ranging from lead optimization to phase II, we have built a strong patent portfolio and we now cover the three major HLA molecules, corresponding to around 80% of cancer patients."
Vaxon Biotech develops therapeutic vaccines against cancer, based on its proprietary technology of optimized cryptic peptides, which are protected by ten patent families. All vaccines developed by Vaxon target universal tumor antigens and therefore have wide-ranging applications in cancer treatment.
