The Roche group has moved into gene therapy and simultaneously strengthened its franchise in haemophilia with the acquisition of Spark Therapeutics Inc, one of a small number of gene therapy companies in the world with a product on the market. The all-cash transaction is valued at approximately $4.3 billion, representing a substantial premium to Spark’s current stock price. Nonetheless, it is below the $8.7 billion that Novartis paid for AveXis Inc and the $9 billion Celgene Corp paid for Juno Therapeutics in 2018 – both gene therapy companies.
