Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This trial is testing whether using a CPAP machine — a device that gently pushes air into your airways while you sleep — can help people with both chronic kidney disease and sleep apnea better control their blood pressure and protect their kidneys. Researchers want to know if treating sleep apnea can reduce the number of blood pressure medications you need and slow down kidney disease. The study will compare people who use CPAP to those who receive standard blood pressure care alone.
Many people with kidney disease also have sleep apnea, but doctors are not sure if treating the sleep apnea actually helps the kidneys or blood pressure. This trial will help answer that important question and may change how doctors care for patients with both conditions.

If you join this study, you will first have a sleep test to confirm whether you have sleep apnea. If you do, you'll be randomly assigned to either use a CPAP machine nightly or continue with standard blood pressure treatment. You'll visit the clinic at baseline and then at 3, 6, 9, and 12 months for blood pressure checks, blood tests, and other assessments. At the beginning and end of the year, you'll also have special tests like eye exams and heart ultrasound to see how your organs are doing. The study team will adjust your blood pressure medications as needed and monitor you closely throughout.
