To establish the experiences with and preferences towards existing thrombopoietin-receptor agonist (TPO-RA) treatments of individuals with immune thrombocytopenia (ITP) in the UK and Ireland, based on treatment attributes. Responses from UK and Ireland individuals with ITP were collected in a pan-European online survey (TRAPeze, [Thrombopoietin-Receptor Agonist Patient experience survey]) from 18 September 2020 to 18 February 2021. TRAPeze was a survey of treatment preference regarding TPO-RAs (using a discrete choice experiment design), participant demographics, disease characteristics, treatment history, overall satisfaction with therapy, direct healthcare resource utilization and wider social impact. The survey was completed by 32 UK respondents. Characteristics with the greatest influence on preference towards TPO-RA treatments were method of administration (odds ratio (OR) 5.6, 95% confidence interval (CI) 3.2–10.1) and drug-food interactions (OR 3.2, 95% CI 1.8–5.7). Particularly, participants were more likely to select an oral tablet over a subcutaneous injection (OR 7.4, 95% CI 3.6–15.1) and a treatment without food restrictions rather than with food restrictions (OR 3.6, 95% CI 1.8–6.8). This is the first study to quantify the preference of individuals with ITP towards TPO-RA treatment attributes and demonstrates preference for orally administered treatments, without drug-food interactions.
