Study Description
The purpose of this study is to assess the safety, tolerability, pharmacokinetics and pharmacokinetics, and pharmacodynamics of HJB647 following single dose administration in Japanese healthy participants with elevated blood pressure and multiple dose administration with up titration in Japanese patients with hypertension, to support future clinical development of HJB647 Randomized, placebo-controlled, participant- and investigator-blind study consisting of two parts:
* Part 1 (SAD part): Single oral dose in healthy participants. Sentinel dosing will be applied in each cohort.
* Part 2 (MAD part): Multiple oral doses in patients with hypertension. Safety reviews will guide dose escalation and up-titration.

Eligibility Criteria
Inclusion Criteria:
* Japanese healthy participants with elevated blood pressure (Part 1) and patients with mild-to-moderate hypertension (Part 2)

* Axillary body temperature: 35.0-37.5 °C
* Heart rate: 50-90 bpm
* Blood pressure criteria are as follows:
* Part 1: Healthy Participants with Elevated Blood Pressure Screening: Systolic Blood Pressure (SBP): 120 ≤ SBP ≤ 139 mmHg; Diastolic Blood Pressure (DBP): 60 ≤ DBP ≤ 94 mmHg Baseline (Day -1): SBP: 120 ≤ SBP ≤ 179 mmHg; DBP: 60 ≤ DBP ≤ 109 mmHg

Exclusion Criteria:
* Significant illness, including infectious diseases that have not resolved within 30 days prior to baseline
* History or current diagnosis of ECG or cardiac abnormalities indicating significant risk of safety for participants such as:
* Concomitant clinically significant cardiac arrhythmias, e.g., sustained ventricular tachycardia, and clinically significant second- or third-degree AV block without a pacemaker.
* History of familial long QT syndrome or known family history of Torsades de Pointes
* Resting QT interval corrected by Fridericia's formula (QTcF) ≥ 450 msec (male) or ≥ 460 msec (female) at screening
* At screening, hypokalemia or hypomagnesemia defined as potassium or magnesium values below the LLN on repeat measurement, or laboratory abnormalities indicating hypothyroidism, as determined at the discretion of the investigator
* HbA1c ≥ 7.0% or LDL cholesterol ≥ 180 mg/dL or triglycerides ≥ 250 mg/dL
* Use of any prescription drugs or herbal supplements within 4 weeks prior to initial dosing, and/or OTC medication or dietary supplements (vitamins included) within 2 weeks prior to initial dosing
* Women of childbearing potential
