KBP-5074 for High Blood Pressure and Chronic Kidney Disease
(Clarion-CKD Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new drug, KBP-5074, to determine its effectiveness for people with chronic kidney disease (CKD) and difficult-to-control high blood pressure. The study compares KBP-5074 with a placebo (a pill with no active medicine) to assess its efficacy and safety. It suits individuals with stage 3b or 4 CKD who are taking at least two medications for high blood pressure but still have readings of 140/90 or higher. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.
Will I have to stop taking my current medications?
The trial requires that you continue taking your current blood pressure medications without any dose changes for at least 4 weeks before the screening. However, you must stop taking certain medications like mineralocorticoid receptor antagonists, potassium-sparing diuretics, and some others before joining the trial.
Is there any evidence suggesting that KBP-5074 is likely to be safe for humans?
Research shows that KBP-5074 has been tested for safety in people with chronic kidney disease and high blood pressure. Earlier studies found it effectively lowers blood pressure. However, some participants experienced high potassium levels in their blood, known as hyperkalemia, which is important to consider when evaluating this treatment.
Although researchers are still studying this treatment, its presence in a later phase of trials suggests some evidence of safety. Discuss any potential risks with a healthcare provider before joining a trial.12345Why do researchers think this study treatment might be promising?
Most treatments for high blood pressure and chronic kidney disease, like ACE inhibitors or ARBs, work by relaxing blood vessels and reducing fluid retention. But KBP-5074 works differently, targeting the mineralocorticoid receptor more selectively. This approach aims to reduce side effects often seen with similar drugs, such as hyperkalemia (high potassium levels). Researchers are excited because this selective action may provide effective blood pressure and kidney protection with fewer complications.
What evidence suggests that KBP-5074 might be an effective treatment for high blood pressure and chronic kidney disease?
Research has shown that KBP-5074, which participants in this trial may receive, effectively lowers blood pressure in individuals with advanced chronic kidney disease and difficult-to-control high blood pressure. One study found that this treatment reduced systolic blood pressure, the top number in a blood pressure reading. KBP-5074 blocks certain hormones that can raise blood pressure. Some patients might experience high potassium levels, known as hyperkalemia, as a side effect. Overall, these findings suggest that KBP-5074 can help manage blood pressure in those with both kidney disease and high blood pressure.12567
Are You a Good Fit for This Trial?
Adults with stage 3b or 4 chronic kidney disease (CKD) and uncontrolled high blood pressure despite taking two or more antihypertensive medications. Participants should have a BMI between ≥19 to <45 kg/m^2, stable medication doses for at least four weeks, and systolic blood pressure between ≥140 and <180 mm Hg.Inclusion Criteria

Trial Overview
The trial is testing the effectiveness of KBP-5074 compared to a placebo in managing hypertension in patients with moderate to severe CKD. It's a phase 3 study where participants are randomly assigned to either the drug or placebo group without knowing which one they receive.
