Every phase 2 or 3 drug trial that was recruiting, about to open or still running for triple-negative breast cancer on ClinicalTrials.gov in September 2026, with the hospitals in the United Kingdom that take part named where the registry lists them.
The ClinicalTrials.gov v2 API was searched on 24 September 2026 for interventional phase 2, 2/3 and 3 studies naming triple-negative breast cancer that were recruiting, not yet recruiting, enrolling by invitation or (for phase 3 and 2/3) active but closed to recruitment: 395 studies, of which 92 were already in the corpus and 18 are hand-written here. The 213 new registry-only records linked here carry the registry facts (title, sponsor, enrolment, dates, interventions, conditions, the triple-negative eligibility sentence and the countries) and no outcomes; trials with a HER2-positive or hormone-receptor-positive cohort alongside a triple-negative one are left out. Of the 213, 146 are phase 2, 32 phase 1/2, 31 phase 3 and 4 phase 2/3; 125 are recruiting, 75 not yet recruiting, 3 enrolling by invitation and 10 phase 3 or 2/3 trials active but closed. Most are run from China, the United States, France and Italy; the United Kingdom appears as a site in the hand-written UK trials (PARTNER at 30 hospitals, PHOENIX at 6, c-TRAK TN at 17, DIAMOND and BARBICAN at Barts, A-BRAVE at 8) and in the industry phase 3 trials ASCENT-03, ASCENT-04, ASCENT-05, TROPION-Breast02, 03, 04 and 05, CAPItello-290 and BEGONIA, whose UK sites are quoted on each record. The ISRCTN registry lists 41 hits for the same search, almost all dual-registered on ClinicalTrials.gov (DIAMOND is one), plus observational and imaging studies not carried here.
