Adequate methods of contraception are defined as those that result in a low failure rate ( 20 mIU/L. Women who are taking hormone replacement therapy (HRT) do not have to have FSH assessments, but the amenorrhea (before starting HRT) must have been naturally (spontaneously) occurring and have been accompanied by an appropriate clinical profile (eg, age appropriate and history of vasomotor symptoms); 7.Males with partners who are WOCBP must agree to use condoms plus spermicide and their female partner must also be using contraception (eg, hormonal or intra-uterine device). This double contraception must be used from the first dose of study drug until at least 90 days after the last dose of study drug; 8. Males must also refrain from donating sperm during the study and for 90 days after the last dose; 9.Capable of understanding the written informed consent, provide signed and witnessed written informed consent before any study-specific procedure, and agree to comply with protocol requirements. Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 170 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age ran

| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of KBP-5074 in patients with moderate-to-severe Chronic kidney disease (CKD) on uncontrolled hypertension (eg, Grade 1 to 2 systolic hypertension – ESC/ESH) as determined by change in trough cuff seated systolic blood pressure (SBP) from baseline to Day 84.;Secondary Objective: To evaluate the change in trough cuff seated diastolic blood pressure from baseline to Day 84; To evaluate the change in 24-hour mean, daytime mean, nighttime mean, morning mean, last 6 hours of the dosing interval mean, SBP, DBP, mean arterial pressure and heart rate from baseline to Day 84 in a subset of patients as measured by 24-hour ambulatory blood pressure monitoring; To evaluate the change and percent change in urine albumin-to-creatinine ratio from baseline to Day 84 or microalbuminuria; To evaluate the change in serum aldosterone and plasma renin levels from baseline to Day 84; To evaluate the incidence of hyperkalemia, incidence of severe hyperkalemia and incidence of patients with serum potassium > 5.0 mmol/L; To evaluate the change in serum potassium levels from baseline to Day 84; To evaluate the changes in estimated glomerular filtration rate and creatinine levels > 30% throughout the study period; To evaluate population pharmacokinetics of KBP-5074.;Primary end point(s): The primary efficacy variable is the change in trough-cuff resting seated SBP from baseline to Day 84. ;Timepoint(s) of evaluation of this end point: Day 84 | — |
Secondary
