Abstract

Introduction: TRV027, a ‘biased’ ligand of the angiotensin II type 1 receptor (AT1R), did not affect a composite clinical outcome at 30 days in a phase 2b acute heart failure (AHF) trial (BLAST-AHF). Methods: Post-hoc analyses from BLAST-AHF (n = 618) examined the effects of TRV027 by baseline systolic blood pressure (SBP) on changes in renal function and 180-day outcomes. Interactions between baseline SBP and select endpoints were identified utilizing a subpopulation treatment effect pattern plots (STEPP) analysis, then grouping of patients by SBP tertile: < 127, ≥ 127 to < 140, and ≥ 140 mmHg. Results: A trend towards increased creatinine in the first 3 days was noted in the lower SBP tertile, while in those in the higher two tertiles, TRV027, especially the 1 mg/h dose, reduced creatinine at days 5 and 30. Beneficial effects on 180-day all-cause mortality and cardiovascular (CV) death or readmission were observed in the two higher SBP tertiles (SBP ≥ 127 mmHg) in the TRV027 1 mg/h dose group (all-cause mortality HR 0.39, 95% CI 0.14–1.06, p = 0.056; CV death or HF/RF rehospitalization HR 0.53, 95% CI 0.28–1.01, p = 0.049), while more adverse outcomes were observed in patients in the lower SBP tertile. Conclusions: This post-hoc analysis of the BLAST-AHF study suggests contrasting effects of TRV027 by baseline SBP, with trends towards lower 180-day event rates in patients enrolled with higher baseline SBP, especially when given lower doses of TRV027.
