The article discusses intimately a number of the regulatory guidelines for gene remedy approval. On the time the article as revealed, 7 gene therapies had obtained advertising authorization. These are:
- Glybera (alipogene tiparvovec). Accredited for familial lipoprotein lipase deficiency underneath distinctive circumstance in Europe.
- Imlygic (talimogene laherparepvec). Accredited for unresectable melanoma in Europe underneath normal approval (with extra monitoring) and within the US via a quick observe approval.
