Brief Summary

This study aims to compare the efficacy and safety of Sacubitril/Valsartan versus Valsartan in patients with essential hypertension and type 2 diabetic nephropathy over a 12-week treatment period, including two treatment groups, with a total of 297 eligible subjects randomly assigned in a 2:1 ratio to either the experimental group or the control group.Subjects will participate in the study through two phases: the screening period and the follow-up period.The primary outcome measure is the change in systolic blood pressure from baseline after 12 weeks of treatment.

  From enrollment to the end of treatment at 12 weeks

Secondary Outcomes (9)

  From enrollment to the end of treatment at 12 weeks

• Changes in daytime and nighttime ambulatory blood pressure

  From enrollment to the end of treatment at 12 weeks

• Rate of dipper blood pressure restoration

• Rate of blood pressure achievement

  From enrollment to the end of treatment at 12 weeks

• Rate of hypertension treatment response

  From enrollment to the end of treatment at 12 weeks

Study Arms (2)

Experimental

EXPERIMENTAL

Initial Dose: The starting dose of Sacubitril/Valsartan is 200 mg once daily. Dose Adjustment: If blood pressure targets (SBP \< 130 mmHg and DBP \< 80 mmHg) are not achieved after 2 weeks of treatment, the dose of Sacubitril/Valsartan should be doubled to 400 mg once daily. Additional Treatment: If blood pressure targets are still not met after an additional 2 weeks of treatment, Nifedipine controlled-release tablets (30 mg once daily) should be added to the regimen.

Drug: Sacubitril/Valsartan

Comparator

ACTIVE COMPARATOR

Initial Dose: The starting dose of Valsartan is 80 mg once daily. Dose Adjustment: If blood pressure targets (SBP \< 130 mmHg and DBP \< 80 mmHg) are not achieved after 2 weeks of treatment, the dose of Valsartan should be doubled to 160 mg once daily. Additional Treatment: If blood pressure targets are still not met after an additional 2 weeks of treatment, Nifedipine controlled-release tablets (30 mg once daily) should be added to the regimen.

Drug: Valsartan

Interventions

Sacubitril/Valsartan DRUG

Sacubitril/Valsartan is a novel antihypertensive medication composed of an angiotensin II receptor blocker (ARB) Valsartan and a neprilysin inhibitor Sacubitril in a 1:1 molar co-crystal form. Sacubitril is a prodrug that, once ingested, is metabolized by esterases into its active form, which inhibits neprilysin activity. Neprilysin has various substrates, including natriuretic peptides and angiotensin II (Ang II). By inhibiting neprilysin, the levels of natriuretic peptides that have antihypertensive and organ-protective effects are increased. The other component, Valsartan, effectively inhibits the Ang II type 1 receptor (AT1R), providing additional antihypertensive and organ-protective effects. The co-crystal structure ensures that Sacubitril and Valsartan have similar absorption and elimination rates, thereby synchronizing their pharmacological effects.

Experimental

Valsartan DRUG

Valsartan, effectively inhibits the Ang II type 1 receptor (AT1R), providing both antihypertensive and organ-protective effects.
