gene therapy

Gene therapy is medical technology that aims to produce a therapeutic effect through the manipulation of gene expression or through altering the biological properties of living cells.

The first attempt at modifying human DNA was performed in 1980, by Martin Cline, but the first successful nuclear gene transfer in humans, approved by the National Institutes of Health, was performed in May 1989. The first therapeutic use of gene transfer as well as the first direct insertion of human DNA into the nuclear genome was performed by French Anderson in a trial starting in September 1990. Between 1989 and December 2018, over 2,900 clinical trials were conducted, with more than half of them in phase I. In 2003, Gendicine became the first gene therapy to receive regulatory approval. Since that time, further gene therapy drugs were approved, such as alipogene tiparvovec (2012), Strimvelis (2016), tisagenlecleucel (2017), voretigene neparvovec (2017), patisiran (2018), onasemnogene abeparvovec (2019), idecabtagene vicleucel (2021), nadofaragene firadenovec, valoctocogene roxaparvovec and etranacogene dezaparvovec (all 2022).
