Derived from Strategic Transactions, Informa’s premium source for tracking life sciences deal activity, the Dealmaking column is a survey of recent health care transactions listed by relevant industry segment – In Vitro Diagnostics, Medical Devices, and Pharmaceuticals – and then categorized by type – Acquisition, Alliance, or Financing. This month’s column covers deals announced January 2020.

Gene therapy dominated the top December deals, with a $2.9bn alliance between Roche and Saretpta for DMD treatment SRP9001, and Astellas's $3bn acquisition of Audentes Therapeutics. Follow-on public offerings made up close to or more than half of both biopharma and device financing.
