摘要
To establish pan-European consensus on tapering and discontinuing thrombopoietin receptor agonists (TPO-RAs) in patients with immune thrombocytopenia (ITP), we applied a three-step Delphi technique consisting of a one-to-one interview round and two online survey rounds. Three healthcare professionals (HCPs) from Italy, Spain, and the United Kingdom formed the Steering Committee (SC), which advised on study design, panelist selection, and survey development. A literature review also informed the development of the consensus statements. Likert scales were used to collect quantitative data on panelists' level of agreement. Twelve hematologists representing nine European countries assessed 121 statements spanning three categories: (1) patient selection; (2) tapering and discontinuation strategies; (3) post-discontinuation management. Consensus was reached on approximately half of the statements in each category (32.2%; 44.6%; 66%). Panelists agreed on patients' main selection criteria, patients' involvement in decision-making, tapering strategies, and follow-up criteria. Areas not reaching consensus were risk factors and predictors of successful discontinuation, monitoring intervals, and rates of successful discontinuation or relapse. This lack of consensus signals knowledge and practice gaps among European countries and suggests the need for the development of clinical practice guidelines that outline a pan-European, evidence-based approach to tapering and discontinuing TPO-RAs.Immune thrombocytopenia (ITP) is a condition that may cause extensive bruising and excessive bleeding. Another sign is a pattern of small reddish-purple dots resembling a rash. ITP is treated with a class of medications known as thrombopoietin receptor agonists (TPO-RAs), which include eltrombopag, avatrombopag, and romiplostim. Sometimes the beneficial effects of the medication last even after the patient stops taking it, which means that some patients can be tapered off it. This paper presents the results of a Delphi panel—a method of research that gathers insights from experts—about tapering and discontinuing TPO-RAs. There were 12 physicians from nine European countries on the Delphi panel, all practicing hematologists with expertise in tapering and discontinuing TPO-RAs in patients with ITP. Panelists were presented with a total of 130 statements over three survey rounds. At the end of Round Three, 52 statements (40%) achieved consensus (response pattern of ≥80% “Agree”), and six statements (4.6%) achieved dissensus (response pattern of ≥80% “Disagree”). Consensus was achieved on the appropriateness of tapering the dose of the TPO-RA for two to three months prior to attempting discontinuation. The panel also reached consensus on considering tapering in a slower fashion (six to 12 months) for patients showing suboptimal response to TPO-RAs. More than half the survey’s statements did not achieve consensus or dissensus. This signals that knowledge gaps exist and highlights the importance of conducting prospective, real-world evidence studies to identify best practices and develop pan-European guidelines for tapering and discontinuing TPO-RAs.
