Thrombopoietin Receptor Agonist Patient experience survey

Real world evidence Burden of Illness cross-sectional study (discrete choice experiment and exploratory questions) to define patient preference towards existing TPO-RAs, to describe disease characteristics, patterns of treatment and satisfaction with therapy and to describe patient demographics, resource use, work and productivity and social impact.
Men or women ≥18 years of age; Formal diagnosis of primary ITP according to the ASH and ICR guidelines; Currently or have previously received a TPO-RA (either eltrombopag and/or romiplostim) in the last 12 months; Have been treated with a TPO-RA for a minimum of 3 months, with at least some of the treatment received in the last 12 months; Provide written informed consent; Ability to understand and respond in English; this does not need to be the participants’ first language or even their own language if they wish to use their own translator. If recruitment appears to be limited by this, then translations of the survey will be made. Further plans for deployment will also see the survey translated into French, German, Italian and Spanish

Participant demographics affect the health state.
TPO-RA treatment affects the severity of symptoms, overall health condition, health state, overall satisfaction with therapy and reasons for discontinuation.
TPO-RA treatment affects direct healthcare resource utilisation and costs.
TPO-RA treatment affects wider healthcare resource use and costs.

Primary endpoint (Participant preferences (or ‘choice’) towards TPO-RA product characteristics): discrete choice experiment through web platform, starting 1 August 2021 (pending ERC approval) and ending 31 December 2021. Participants have 1 week to fill out the online survey and are expected to need a total of 20 minutes for this.

Secondary endpoints (Participant demographics and disease characteristics, Patterns of treatment and overall satisfaction with therapy, Direct healthcare resource utilisation and costs & Wider social impact, healthcare resource use and costs): patient burden survey through web platform, starting 1 August 2021 (pending ERC approval) and ending 31 December 2021. Participants have 1 week to fill out the online survey and are expected to need a total of 10 minutes for this.
