Jan Geissler from the Leukemia Patient Advocates Foundation, Germany, provides us an overview of the new big £4 million data project, HARMONY, a 5-year publicly-funded, public-private partnership. He explains how the project is focused on the coordination of stakeholder input from patient organisations, HTA bodies, regulators and other stakeholders and notes its importance in forming a data pool that will allow research to be performed on outcome parameters. This interview was filmed at the European Hematology Association (EHA) 2017 Annual Congress in Madrid, Spain.
