TRAIT
Real World Use of Thrombopoeitin Agonists in the Management of Immune Thrombocytopenia (TRAIT Study)
TRAIT is a research study examining the “real world” use of Thrombopoetin-Receptor Agonists (TRAs) in the management of Immune Thrombocytopenia (ITP) in the UK. It is led by Nichola Cooper from Imperial College Healthcare NHS Trust.
There are few randomised controlled trials looking at TRAs, such as romiplostim (Nplate) or eltrombopag (Revolade) and therefore limited information on the benefits and potential harms with long term use, either as 3rd line agents in ITP (after 2 prior treatment types) or in situations where they are used earlier on in the course of treatment or for treatment of ITP caused by another illness (secondary ITP).
This retrospective study recruited patients who were ≥18 years old, had primary or secondary ITP and had received their first prescription for a TRA at least 3 months before being entered into the study.
The study measured response rates, the duration of response and also adverse events and reactions occurring whilst on these medications. It aimed to recruit 200 patients over a 12 month period during 2017 and 2018.
Initially 5 sites were opened across the UK. Before HaemSTAR involvement, recruitment started strongly but tailed off after the first six months. At this point HaemSTAR expressed interest and the study sponsor granted increased funding for 5 further sites to be supported by HaemSTAR.
Five HaemSTAR sites opened rapidly enabling ongoing, above-target recruitment
Real-World Financial Benefit to the NHS from HaemSTAR's Involvement
Through directly attributable HaemSTAR efforts, the NHS received real-world income of £25,100 from the TRAIT study.
