About this trial

The purpose of this clinical study is to evaluate the safety and early effectiveness of a catheter-based procedure that treats a nerve called the right greater splanchnic nerve. The study includes people who have heart failure with preserved ejection fraction (HFpEF). The goal is to learn whether this procedure, performed using the Satera Ablation System, may help improve symptoms and to better understand which patients may benefit most from this treatment in the future.

Eligibility criteria

Qualifiers

Symptoms of HF requiring current (intermittent or continuous) treatment with diuretics for >30 days, AND

NYHA class II with a history of >NYHA class II in the past year, NYHA class III, or ambulatory NYHA class IV symptoms (paroxysmal nocturnal dyspnea, orthopnea, dyspnea on mild or moderate exertion) at screening or signs of HF (any rales post cough, chest x-ray demonstrating pulmonary congestion), AND

Ongoing stable GDMT HF management (unless unable to tolerate GDMT) and management of potential comorbidities according to the 2022 ACCF/AHA Guideline for the Management of Heart Failure (Class 1 and 2a recommendations), with no significant changes [≥100% increase or ≥50% decrease] for a minimum of 1 month (30 days) prior to screening, that is expected to be maintained without change for at least 6 months. Participants cannot have started a glucagon-like peptide (GLP)-1 or gastric inhibitory peptide (GIP) agonist within the last 6 months or plan to start a GLP-1 or GIP agonist within the ensuing 6 months after enrollment.

LVEF ≥50% (site-determined by transthoracic echocardiography) within the past 6 months.

Disqualifiers

MI (type I) and/or percutaneous cardiac intervention within 3 months prior to screening; CABG in past 3 months prior to screening, or current indication for coronary revascularization.

Cardiac resynchronization therapy initiated within 3 months prior to screening.

ACC/AHA/ESC Stage D HF or non-ambulatory NYHA Class IV HF.

Inotropic infusion (continuous or intermittent) within 6 months prior to screening.
