OCEANSIDE, CA– Therapeutic Solutions International, Inc., (OTC PINK: TSOI) announced today the signing of an exclusive intellectual property license agreement with Gustave Roussy Transfert of Villejuif, France for an issued U.S. patent covering the clinically tested “Dexosome” cancer immunotherapy product.
Dexosomes are exosome nanoparticles generated by dendritic cells, which have previously been used by investigators at Anosys, Inc., in collaboration with researchers at Duke University, for treatment of cancer patients as part of an FDA-cleared Phase I clinical trial(1). The licensed patent was invented by internationally-renowned immunologists Sebastian Amigorena, Doctor at the Curie Institute, and Laurence Zitvogel, Professor at Gustave Roussy. While the patent was issued when licensed to Anoysis, subsequent to merger between Anosys, Inc. and Epimmune, the patent was reverted to Gustave Roussy Transfert. The patent covers means of generating therapeutically-effective dexosomes, which can act as a platform for loading any tumor antigen desired.
