Many variants of herpes simplex virus have been considered for viral therapy of cancer; the early development of these was thoroughly reviewed in the journal Cancer Gene Therapy in 2002.[1] This page describes (in the order of development) the most notable variants—those tested in clinical trials: G207, HSV1716, NV1020 and Talimogene laherparepvec (previously Oncovex-GMCSF). These attenuated versions are constructed by deleting viral genes required for infecting or replicating inside normal cells but not cancer cells, such as ICP34.5, ICP6/UL39, and ICP47.
