Pan-Stakeholder Core Outcome Set (COS) Definition for Selected Hematological Malignancies - Results of the Harmony Alliance

Introduction: Commonly accepted standardized sets of outcomes to be measured in clinical trials are still limited. In accordance, outcome measures vary widely between clinical trials even within defined hematological malignancy (HM) entities. Definition of a core outcome set (COS), which represents a standardized agreed set of outcomes that should be measured and reported in all trials for the respective disease of interest may improve this situation. Furthermore, respective COS should address the need of all stakeholders, i.e. not only the views of physicians and industry running the trials, but also the interests of patients and regulators. To perform a task like this, HARMONY - Healthcare Alliance for Resourceful Medicine Offensive against Neoplasms in Hematology - a private-public partnership established in January 2017, including 53 partners and 43 associated partners in 18 different European countries and also 6 patient organizations, poses an optimal platform to define COS for HMs.
