Assessing Physician and Hemophilia A Patient Reasons and Expectations for Switching Treatment to Kovaltry & Jivi: A Nested Study Within an Existing Registry

This US study aims to assess hemophilia A patient characteristics and reasons for switching from both patient/caregiver and physician perspectives. For this purpose, this research study will include hemophilia A patients who have switched from an existing therapy to Kovaltry or Jivi. In doing so, real world evidence will be obtained from both patient and physician perspectives offering key insights for effective therapeutic management of patients with hemophilia A and to more fully understand what drives patient switching from a patient perspective and a physician perspective.
