What this phase means
This study does not use the classic phase 1–4 drug ladder. It may be a device, a behavior program, a surgery timing study, or an early feasibility test.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Right Greater Splanchnic Nerve (GSN) ablation, or Sham Control. The registry lists allocation as randomized. This study is a small, early-stage clinical trial designed to test whether a new catheter-based procedure is safe and may help people with heart failure with reduced ejection fraction (HFrEF).
They plan to enroll about 50 people at 9 sites. Taking part typically means using or being fitted with a device, a procedure as part of the study plus check-ins.
