Multicenter, retrospective, European study to evaluate standards of use of thrombopoietin receptor agonists in adult patients with primary immune thrombocytopenia (ITP). Data will be collected by retrospectively reviewing the medical records of patients with ITP who started treatment with thrombopoietin analogues (regardless of phase of the disease) between January 2014 and December 2016.
Each of the 18 sites across UK, Spain, Italy, Norway, France and Switzerland will collect the data from all the patients with ITP who meet the inclusion criteria and agree to participate in the study by signing the informed consent. In order to prevent screening bias, the medical records will be consecutively screened by the investigators, starting with the oldest (regarding start of ITP therapy with TPO-RA), by selecting patients who started therapy with agonists on the date nearest to January 2014. The data will be obtained in a retrospective, non-interventionist manner to meet this study’s objective, by reviewing the patient’s medical records.
The project is coordinated by ERCI founding member Maria Luisa Lozano, from Hospital Universitario Morales Meseguer, Universidad de Murcia, Spain and is conducted in collaboration with the Hematology Project Foundation, Vicenza, Italy.
