Summary

This study was designed to test the safety and tolerability of a new drug called JK07 in people with heart failure and a specific type of high blood pressure in the lungs. It planned to enroll about 20 to 30 adults aged 18 to 85. However, the study was withdrawn before any participants were enrolled, so no results are available.
