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 people with pulmonary arterial hypertension (a serious condition where blood pressure in the lungs becomes dangerously high) benefit from trying two different drug combinations in sequence. You'll receive a small implanted device to monitor your heart and lung pressures at home, then take or — both approved medications for this condition — in different combinations over several months while doctors measure how well each works for you.
Many people with this condition don't improve enough on standard treatment alone. This trial aims to find out whether trying different medication combinations in the same person helps doctors figure out which works best for each individual, and whether home monitoring devices can help catch improvements early.

You will have a small monitoring device surgically implanted in your chest that tracks your heart and lung pressures remotely. Over approximately 27 weeks, you'll switch between two different medication combinations — taking one set of drugs while gradually increasing the dose, then switching to the other combination and doing the same. At several timepoints, you'll come to the hospital for heart imaging (MRI), heart catheterization, blood tests, and a walking test to measure how well each medication combination is working for you. The doctors will use both the device readings and these clinic tests to compare which treatment helps you most.
