State Food and Drug Administration
The first oncolytic virus to be approved by a regulatory agency was a genetically modified adenovirus named H101 by Shanghai Sunway Biotech. It gained regulatory approval in 2005 from China's State Food and Drug Administration (SFDA) for the treatment of head and neck cancer. Talimogene laherparepvec is the world's first approved oncolytic immunotherapy, i.e. it was also designed to provide systemic anti-tumor effects through the induction of an anti-tumor immune response.
