BoB@JPM: Gene Writing With Tessera's Michael Severino, M.D.

Flagship Pioneering plucked Michael Severino, M.D. away from AbbVie to run point at Tessera, a startup it's backed to pioneer a new category of genetic medicine it calls gene writing. The Business of Biotech caught up with Severino at the JP Morgan Healthcare Conference in San Francisco last month. We learned what lured him away from leadership positions at Merck, Amgen, and AbbVie, how gene writing differs from gene therapy and gene editing, why the team at Tessera believes its technologies can write and rewrite DNA at the scales necessary to cure most genetic diseases, and where he plans to take the company from here.
