HaemTRIAL Explorer
Built from the NIHR CRN Central Portfolio Management System (last CPMS export: 29 September 2026). Study status, open sites and recruitment numbers change frequently — treat this as a snapshot, confirm details via each study's own link before relying on them. Hospital county and condition tags are best-effort, assistant-derived labels for filtering, not NIHR data — see the note in the footer.

Currently recruiting = open on the NIHR portfolio with active sites. Coming soon = in setup, not yet open to recruitment. Recently closed = dropped off the live NIHR export and confirmed closed, kept here for 6 months (for example, to cross-reference a study's results publication against when it closed) before being removed from this page — every closed study remains on permanent record in HaemTRIAL's internal tracker regardless.
Subspecialty is NIHR's own classification. Hospital county / area is derived by the assistant from each site's trust name (not a CPMS field) — best-effort, not postcode-verified; Scottish sites are shown by NHS health-board area and the one Northern Ireland site by nation, rather than an English county. The clickable region map groups counties into the 9 standard English regions, Wales, 5 Scottish health-board areas and Northern Ireland — a schematic hex layout (like the familiar ONS/BBC hex maps of the UK), not a literal or precise geographic map. Condition is derived by the assistant from each study's own title and PICO/summary text by keyword match — a study can carry more than one tag, and a study with no tag simply doesn't mention a recognised keyword in the text available (shown as "Not yet classified"). All three of these groupings beyond subspecialty are new, assistant-added aids for browsing this page — flag any that look wrong.
Excludes studies primarily about leukaemia, lymphoma, myeloma, MPN and related malignant/transplant categories (medical haematology scope) — see the HaemTRIAL malignancy-exclusion rule.
