What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new combination treatment for individuals with chronic kidney disease (CKD) who also have high blood pressure and protein in their urine. The study examines how lorundrostat, a drug that blocks a hormone known to raise blood pressure, works with dapagliflozin, a medication used to lower blood sugar and blood pressure, to safely reduce blood pressure. It targets those who have maintained a stable regimen, including an ACE inhibitor or ARB, for at least two months. Participants should have CKD with protein in their urine and manage high blood pressure between 135-180 mmHg. This trial may suit those who haven't found relief from current treatments and experience these specific symptoms. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering a chance to benefit from innovative therapies.

Do I have to stop taking my current medications?

The trial requires you to stay on a stable treatment with an ACE inhibitor or an Angiotensin receptor blocker for at least 2 months before screening. You cannot use epithelial sodium channel inhibitors or mineralocorticoid receptor antagonists from 4 weeks before screening and during the study.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that lorundrostat, a medication that blocks a hormone involved in blood pressure regulation, is generally well-tolerated. In studies, individuals with high blood pressure experienced significant reductions without major safety issues. Most side effects were mild, such as dizziness and tiredness.

Studies have also shown that dapagliflozin, a medication that helps the kidneys remove sugar from the body, is safe for people with chronic kidney disease (CKD). It has a good safety record, with no serious side effects like diabetic ketoacidosis (a dangerous condition where acids build up in the blood) reported in patients, whether or not they have type 2 diabetes.

Both lorundrostat and dapagliflozin have shown promising safety results in previous research, suggesting they could be safe options for people with CKD and high blood pressure. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for kidney disease?

Unlike the standard treatments for kidney disease, which often include blood pressure medications and diuretics, Lorundrostat offers a new approach by targeting the aldosterone pathway. This pathway is crucial because aldosterone can contribute to kidney damage by causing inflammation and fibrosis. Researchers are excited about Lorundrostat because it may protect the kidneys more effectively by directly reducing aldosterone production, potentially slowing down the progression of kidney disease. This mechanism of action is different from current options and could offer a new hope for patients with kidney disease.

What evidence suggests that this trial's treatments could be effective for hypertension in CKD patients?

This trial will evaluate the effects of Lorundrostat and Dapagliflozin on kidney disease. Research has shown that Lorundrostat, which participants in this trial may receive, can lower blood pressure and reduce protein in the urine for people with chronic kidney disease (CKD) and high blood pressure. In one study, patients taking Lorundrostat experienced a 9.3 mmHg drop in systolic blood pressure. Another study found that it lowered both blood pressure and the urine albumin-to-creatinine ratio, a key marker of kidney health.

Dapagliflozin, another treatment option in this trial, is already known to slow the progression of kidney disease. Research has shown it can delay the onset of kidney failure by more than six years. These findings suggest that both Lorundrostat and Dapagliflozin may benefit those managing kidney disease and high blood pressure. ^{1 2 5 6 7}

Are You a Good Fit for This Trial?

This trial is for adults with chronic kidney disease and high levels of protein in their urine (albuminuria), who also have high blood pressure. They should be on stable heart medication (ACEi or ARB) for at least 2 months, with specific ranges of kidney function and body mass index.
