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

Overview

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.

Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Cross-Sectional
  • Study Primary Completion Date: May 14, 2020

Detailed Description

This observational study consists of a patient and a physician survey. This survey will consist of questions developed by Bayer and submitted to the Steering Committee of the existing registry, ATHN-2. Once enrolled to participate in the ATHN-2 registry and provided consent to participate in the Bayer nested study, patients who have switched from another product to Kovaltry or Jivi within the past 50 weeks or at the time of enrollment will be prompted to answer the additional survey questions. Conclusion of the ATHN-2 registry is scheduled for 2021. Once data is cleaned and locked by the registry, the data will be delivered to Bayer for conduct of our analyses.

Interventions

  • Drug: New FVIII products
    • Kovaltry or Jivi prescribed by the treating Physician

Arms, Groups and Cohorts

  • Patient/caregiver of Kovaltry or Jivi
    • Patients who are switching factor replacement products to Kovaltry or Jivi and patients who have switched factor replacement products to Kovaltry or Jivi previously
  • Physician Group
    • Physicians participating in the study are associated with US hemophilia treatment centers that are affiliated with the ATHN hemophilia treatment center network
