NT-proBNP Response to Sacubitril/Valsartan in Hospitalized Heart Failure Patients With Reduced Ejection Fraction: TRANSITION Study
Objectives: This study examined the effects of sacubitril/valsartan on N-terminal pro\u2013B-type natriuretic peptide (NT-proBNP) levels and determined patient characteristics associated with favorable NT-proBNP reduction response. Background: NT-proBNP levels reflect cardiac wall stress and predict event risk in patients with acute decompensated heart failure (ADHF). Methods: Post-hoc analysis of the TRANSITION (Comparison of Pre- and Post-discharge Initiation of Sacubitril/Valsartan Therapy in HFrEF Patients After an Acute Decompensation Event) study, including stabilized ADHF patients with reduced ejection fraction, randomized to open-label sacubitril/valsartan initiation in-hospital (pre-discharge) versus post-discharge. NT-proBNP was measured at randomization (baseline), discharge, and 4 and 10 weeks post-randomization. A favorable NT-proBNP response was defined as reduction to 641,000 pg/ml or >30% from baseline. Results: In patients receiving sacubitril/valsartan in-hospital, NT-proBNP was reduced by 28% at discharge, with 46% of patients obtaining favorable NT-proBNP reduction response compared with a 4% reduction and 18% favorable response rate in patients initiated post-discharge (p < 0.001). NT-proBNP was reduced similarly in patients initiating sacubitril/valsartan pre- and post-discharge (reduction at 4 weeks: 25%/22%; 10 weeks: 38%/34%) with comparable favorable response rates (46%/42% and 51%/48% at 4 and 10 weeks, respectively). NT-proBNP favorable response at 4 weeks was associated with lower risk of first heart failure (HF) rehospitalization or cardiovascular death through 26 weeks (hazard ratio: 0.57; 95% confidence interval [CI]: 0.38 to 0.86; p = 0.007). Predictors of a favorable response at 4 weeks were starting dose 6549/51 mg twice daily, higher baseline NT-proBNP, lower baseline serum creatinine, de novo HF, no atrial fibrillation, angiotensin-converting enzyme inhibitor\u2013naive or angiotensin receptor blocker\u2013naive, and no prior myocardial infarction. Conclusions: In-hospital initiation of sacubitril/valsartan produced rapid reductions in NT-proBNP, statistically significant at discharge. A favorable NT-proBNP response over time was associated with a better prognosis and predicted by higher starting dose and predisposing clinical profile.

Initiation of sacubitril/valsartan in haemodynamically stabilised heart failure patients in hospital or early after discharge: primary results of the randomised TRANSITION study
Aims: To assess tolerability and optimal time point for initiation of sacubitril/valsartan in patients stabilised after acute heart failure (AHF). Methods and results: TRANSITION was a randomised, multicentre, open-label study comparing two treatment initiation modalities of sacubitril/valsartan. Patients aged ≥ 18 years, hospitalised for AHF were stratified according to pre-admission use of renin–angiotensin–aldosterone system inhibitors and randomised (n = 1002) after stabilisation to initiate sacubitril/valsartan either ≥ 12-h pre-discharge or between Days 1–14 post-discharge. Starting dose (as per label) was 24/26 mg or 49/51 mg bid with up- or down-titration based on tolerability. The primary endpoint was the proportion of patients attaining 97/103 mg bid target dose after 10 weeks. Median time of first dose of sacubitril/valsartan from. the day of discharge was Day –1 and Day +1 in the pre-discharge group and the post-discharge group, respectively. Comparable proportions of patients in the pre- and post-discharge initiation groups met the primary endpoint [45.4% vs. 50.7%; risk ratio (RR) 0.90; 95% confidence interval (CI) 0.79–1.02]. The proportion of patients who achieved and maintained for ≥ 2 weeks leading to Week 10, either 49/51 or 97/103 mg bid was 62.1% vs. 68.5% (RR 0.91; 95% CI 0.83–0.99); or any dose was 86.0% vs. 89.6% (RR 0.96; 95% CI 0.92–1.01). Discontinuation due to adverse events occurred in 7.3% vs. 4.9% of patients (RR 1.49; 95% CI 0.90–2.46). Conclusions: Initiation of sacubitril/valsartan in a wide range of heart failure with reduced ejection fraction patients stabilised after an AHF event, either in hospital or shortly after discharge, is feasible with about half of the patients achieving target dose within 10 weeks.
