They don't mention it in the article but I believe this is the first big treatment to use CRISPR/Cas9 https://www.ncbi.nlm.nih.gov/m/pubmed/30261221/
This is not true. The treatment they are getting uses a lentivirus transduced T-cell. CRISPR will eventually be used but in the approved products, not yet.
Oh I see, sorry about the confusion.
