Description of intervention(s) / exposure
Treatment: Drugs - Placebo
Treatment: Drugs - KBP-5074

Placebo Comparator: Placebo - All eligible participants will receive KBP-5074 matching placebo, for approximately 2 weeks, during the Open-label placebo Run-In period, then up to 24 weeks during the Double-blind treatment Period and during the Open-label treatment period, and thereafter for 4 weeks, during the randomized Double-blind withdrawal period.

Summary
Brief summary
This Phase 3, randomized, Double-blind, placebo-controlled, 2-arm, parallel-group,
multicenter study with randomized withdrawal will evaluate the efficacy, safety, and
durability of KBP-5074 in adult participants who have stage 3b/4 chronic kidney disease (CKD)
(estimated glomerular filtration rate [eGFR] calculated using the Chronic Kidney Disease
Epidemiology Collaboration [CKD-EPI] formula [eGFR {EPI}] =15 to =44 mL/min/1.73 m^2) and
uncontrolled hypertension (systolic blood pressure (SBP) =140 and <180 mm Hg and taking 2 or
more antihypertensive medications.
