One-Time gene shot aims to mend broken hearts
NCT ID NCT07137338
First seen Jun 27, 2026 · Last updated Jul 01, 2026 · Updated 2 times
Summary
This early-stage trial tests a one-time gene therapy called RP-A701 in 8 adults with dilated cardiomyopathy caused by a faulty BAG3 gene. The therapy uses a harmless virus to deliver a working copy of the gene, aiming to improve heart function. The main goal is to check safety, but researchers will also look for signs that the heart is pumping better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- RP-A701 (a gene therapy using a harmless virus to deliver a working BAG3 gene)
- What this could lead to
- If successful, this could point toward a one-time treatment that improves heart function in people with this inherited form of heart failure.
- What could go wrong
- This is a very early, small trial (8 people) focused on safety, not proof of effectiveness. Gene therapies can cause immune reactions or other side effects.

Inclusion Criteria: Subjects are eligible for inclusion into the study only if all the following criteria apply: 1. Male or female between 18 and 65 years of age at the time of signing the informed consent 2. Capable of and willing to provide signed informed consent 3. Clinical diagnosis of DCM defined as and requiring each of the following: 1. Mild to moderate systolic dysfunction (LVEF ≥ 25% and ≤ 45%) by echocardiography or CMR performed within 3 months of enrollment. 2. Absence of severe coronary artery disease (\>70% stenosis) or active myocardial ischemia as the etiology of LV systolic dysfunction 3. Absence of uncontrolled hypertension, significant cardiac valve disease (i.e., greater than moderate in severity), infiltrative disorder, or systemic disease known to cause cardiomyopathy. 4. Documentation of a pathogenic or likely pathogenic variant in BAG3 5. History of ICD implantation ≥ 3 months prior to enrollment 6. NYHA Class II or III HF symptoms with stable HF therapeutic guideline-directed medical regimen for 30 days prior to enrollment Exclusion Criteria: 1. CV disease that may be related to a genetic etiology other than a BAG3 pathogenic or likely pathogenic variant. 2. Previous participation in a study of gene transfer or gene editing. 3. I.V. inotropic, vasodilator, or diuretic therapy ≤ 30 days prior to enrollment. 4. History of intracardiac thrombosis or arterial thromboembolic events 5. Severe RV dysfunction assessed by echocardiogram or CMR ≤ 12 months prior to screening 6. LVEF \< 25% by echocardiogram or CMR at ≤ 3 months prior to screening 7. NYHA Class I or IV HF
