Randomized, Single-blind, Placebo-controlled Exploratory Clinical Trial to Evaluate the Antihypertensive Efficacy and Safety, Tolerability of KN060 in Patients With Essential Hypertension
The primary objective of this study is to compare the change from baseline in systolic blood pressure between KN060 and placebo in patients with essential hypertension over 12 weeks; the secondary objectives are to assess the safety and tolerability of KN060 and to assess the pharmacokinetic and pharmacodynamic properties and immunogenicity of KN060 in patients with essential hypertension. The main questions it aims to answer are: * To verify the efficacy of KN060 in patients with essential hypertension * Safety of KN060 in Subjects Treated for Essential Hypertension Researchers will compare KN060 to placebo (0.9% sodium chloride 100ml) to assess the antihypertensive effect of KN060. Subjects will : * Receive KN060 or placebo by intravenous drip every two weeks for 6 doses. * AOBP, 24hABPM, HBPM,and safety were monitored and recorded.
• men or women ≥ 18 years of age and ≤ 65 years of age;
• patients with essential hypertension who are not receiving drug therapy or are receiving stable monotherapy (stable therapy: no change in antihypertensive drugs and doses within 30 days before screening);
• AOBP mean sitting SBP ≥ 140 and \< 180 mmHg (at least 5 minutes rest before measurement, 3 measurements averaged over at least 1 minute apart) and mean SBP ≥ 130 and ≤ 160 mmHg at 24 hours ABPM;
