A Study to Investigate the Efficacy of PADN to Improved Functional Capacity and Hemodynamics in Patients With PAH — PADN-PAH  

Pulmonary Arterial Hypertension Clinical Trial

Official title:
A Prospective, Multi-center, Randomized Control Trial to Investigate the Efficacy of Pulmonary Artery Denervation to Improved Functional Capacity and Hemodynamics in Patients With Pulmonary Artery Hypertension

Clinical Trial Summary

Pulmonary arterial hypertension (PAH) is characterized by premature death mainly because of progressive and severe right ventricular failure. Target drugs are reported to be associated with significant improvement of clinical outcome for PAH patients. However, previous studies using those target drugs focused on the change of 6-minute walk distance (6MWD) and or hemodynamic responses. As 6MWD has weak correlation with clinical outcome (time to clinical worsening, TTCW), benefits from target drugs for PAH patients are not clear. We previously reported the safety and efficacy of pulmonary artery denervation (PADN) for treatment of PAH patients who were unresponsive to target drugs. Hence, we design the randomized study to identify the effect of PADN on PAH.

Clinical Trial Description

The current study is designed as a multicenter, randomized and prospective study aiming to compare the effect of PADN on PAH patients. Based on the previous studies, the rate of pulmonary arterial hypertension (PAH)-related event was around 30% after 6-month treatment using target drugs. And our previous data showed that this PAH-related event at 6-month after PADN procedure was 15%. As a result, a total of 270 PAH patients was required, with 135 patients/per group at a ratio of 1:1 randomization. All patients underwent an 18F-DOPA PET/CT scan of pulmonary arteries and the heart, performed at basement. ;
