This 8-week, multi-center, open-label study assessed the safety and efficacy of LCZ696, a first-in-class angiotensin receptor neprilysin inhibitor, in Japanese patients with hypertension and renal dysfunction. Patients (n=32) with mean sitting systolic blood pressure (msSBP) ⩾140 mm Hg (after a 2–5-week washout of previous antihypertensive medications) and estimated glomerular filtration rate (eGFR) ⩾15 and <60 ml min−1 1.73 m−2 received LCZ696 100 mg with an optional titration to 200 and 400 mg in a sequential manner starting from Week 2 in patients with inadequate BP control (msSBP ⩾130 mm Hg and mean sitting diastolic blood pressure (msDBP) ⩾80 mm Hg) and without safety concerns. Safety was assessed by monitoring and recording all adverse events (AEs) and change in potassium and creatinine. Efficacy was assessed as change from baseline in msSBP/msDBP. The mean baseline BP was 151.6/86.9 mm Hg, urinary albumin/creatinine ratio (UACR) geometric mean was 7.3 mg mmol−1 and eGFR was ⩾30 and <60 in 25 (78.1%) patients and was ⩾15 and <30 in 7 (21.9%) patients. Fourteen (43.8%) patients reported at least one AE, which were mild in severity. No severe AEs or deaths were reported. There were no clinically meaningful changes in creatinine, potassium, blood urea nitrogen and eGFR. The geometric mean reduction in UACR was 15.1%, and the mean reduction in msSBP and msDBP was 20.5±11.3 and 8.3±6.3 mm Hg, respectively, from baseline to Week 8 end point. LCZ696 was generally safe and well tolerated and showed effective BP reduction in Japanese patients with hypertension and renal dysfunction without a decline in renal function.
The safety of LCZ696, a novel angiotensin receptorneprilysin inhibitor, was evaluated for the first time in patients with severe hypertension in this 8-week, multicenter, open-label study. Thirty-five Japanese patients with either office systolic blood pressure (SBP) ≥180 mm Hg or diastolic blood pressure (DBP) ≥110 mm Hg received LCZ696 200 mg. If blood pressure was uncontrolled, the LCZ696 dose was increased to 400 mg after 2 weeks (if there were no safety concerns; n=32), followed by an optional addition of another antihypertensive drug (except angiotensin receptor blocker and angiotensin-converting enzyme inhibitor) after 4 weeks (n=21). Reductions in office SBP/DBP (baseline, 173.4 mm Hg/112.4 mm Hg) and pulse pressure (baseline, 61.0 mm Hg) at week 8 were 35.3/ 22.1 mm Hg and 13.2 mm Hg, respectively. The overall incidence of adverse events was 48.6% with no reports of dizziness, hypotension, or angioedema. The LCZ696-based regimen was generally well-tolerated and could present a treatment option for severe hypertension in Asian patients especially in reducing SBP and pulse pressure.
The design of the PARALLEL-HF study is aligned with the PARADIGM-HF study and aims to assess the efficacy and safety of LCZ696 in Japanese HFrEF patients.
