Trial Title: Study of the Safety and Efficacy of LCZ696 on Arterial Stiffness in Elderly Patients With Hypertension

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Key Inclusion Criteria:~1. Male and female patients ≥ 60 years of age.~2. Patients with essential hypertension, untreated or currently taking antihypertensive therapy.~3. Untreated patients must have an office msSBP ≥150 mmHg and \<180 mmHg at Visit 101 and Visit 201 if they are newly diagnosed or have not been treated with antihypertensive drugs for the 4 weeks prior to Visit 1.~4. Treated patients must have an office msSBP ≥140 mmHg and \<180 mmHg at Visit 102 (or Visit 103) and msSBP ≥150 mmHg and \<180 mmHg at Visit 201 if they have been treated with antihypertensive drugs for the 4 weeks prior to Visit 1.~5. All patients must have pulse pressure \>60 mmHg at Visit 201. Pulse pressure is defined as msSBP- msDBP.~6. Patients must have a difference in msSBP within +/-15 mmHg between Visit 201 (randomization) and the visit immediately prior to Visit 201.~Key Exclusion Criteria:~1. Malignant or severe hypertension (grade 3 of WHO classification; msDBP ≥110 mmHg and/or msSBP ≥ 180 mmHg)~2. History of angioedema, drug-related or otherwise.~3. History or evidence of a secondary form of hypertension, including but not limited to any of the following: renal parenchymal hypertension, renovascular hypertension (unilateral or bilateral renal artery stenosis), coarctation of the aorta, primary hyperaldosteronism, Cushing's disease, pheochromocytoma, polycystic kidney disease, and drug-induced hypertension.~4. Transient ischemic cerebral attack (TIA) during the 12 months prior to Visit 1 or any history of stroke.~5. History of myocardial infarction, coronary bypass surgery or any percutaneous coronary intervention (PCI) during the 12 months prior to Visit 1.~6. History of atrial fibrillation or atrial flutter during the 3 months prior to Visit 1, or active atrial fibrillation or atrial flutter on the ECG at screening.

Study Arms:
- LCZ696 (sacubitril/valsartan) (Type: EXPERIMENTAL): Randomized patients received LCZ696 once daily for four weeks, then they force-titrated to a higher dose at Week 4 and stayed on this dose of LCZ696 once daily for the remainder of the treatment period. At week 12, patients with uncontrolled BP allowed to have amlodipine then hydrochlorothiazide (HCTZ) added at intervals of 4 weeks from Week 12 up to Week 24. To maintain the double dummy, double-blind design, 2 tablets (LCZ696, its matching placebo) and 1 capsule (olmesartan matching placebo) were given during the entire study.
- Olmesartan (Type: ACTIVE_COMPARATOR): Randomized patients received olmesartan once daily for four weeks, then force-titrated to a higher dose at Week 4 and stayed on this dose of olmesartan once daily for the remainder of the treatment period. At week 12, patients with uncontrolled BP allowed to have amlodipine then hydrochlorothiazide (HCTZ) added at intervals of 4 weeks from Week 12 up to Week 24. To maintain the double dummy, double-blind design, 2 tablets (LCZ696 matching placebo) and 1 capsule (olmesartan) were given during the entire study.

Based on this trial design, predict the completion outcome and termination type (if applicable).
