ABSTRACTObjective Identify patient preference towards thrombopoietin-receptor agonists (TPO-RAs) and determine the clinical and social impact of immune thrombocytopenia (ITP) in Italy.Methods The Thrombopoietin-Receptor Agonist Patient experience (TRAPeze) survey collected responses from Italian residents from 17th January to 28th February 2022. TRAPeze utilized a discrete choice experiment (DCE) to elicit patient preferences towards TPO-RA attributes and a patient burden survey (PBS) to determine ITP disease characteristics and social impact.Results Seventy-six respondents completed the DCE, of which 69 completed both the DCE and PBS (mean [range] age 45 [18.0–73.0] years, 80% female). TPO-RA attributes with the greatest influence over respondent choice were method of administration (odds ratio [OR] 2.96; 95% confidence interval [CI] 2.16–4.06), drug-food interactions (OR 1.48; 95% CI 1.17–1.86) and frequency of dosing (OR 1.32; 95% CI 1.15–1.52). Respondents were more likely to prefer therapies administered orally over subcutaneous injection (OR 3.76; 95% CI 2.51–5.63), once weekly over once daily (OR 1.83; 95% CI 1.26–2.65), and therapies without food restrictions over with restrictions (OR 1.58; 95% CI 1.17–2.14).The most frequently reported symptoms were bruising (82%), petechiae (65%) and fatigue (64%). Most respondents (84%) felt ITP impacted familial relationships and 71% of employed respondents reported fatigue influencing their ability to work, with 31% reducing working hours.Conclusion Although responses indicated a moderate perception of general health, ITP clearly impacted respondent work and social life. Our findings demonstrate respondents preferred TPO-RAs delivered orally, with less frequent dosing and without food restrictions.
