About This Trial

This is a Phase 1, open-label, dose-escalation trial to characterize the safety, tolerability, and preliminary efficacy of RP-A701 following a single IV administration in high-risk adult patients with BAG3-DCM.

What Stage of Research Is This?

Phase 1 trials test a new treatment for the first time in humans, focusing on safety, dosing, and how the body processes the drug. For Dilated Cardiomyopathy (DCM), a Phase 1 study typically enrolls a small number of participants — often healthy volunteers or patients who have exhausted standard treatment options. Phase 1 results determine whether a treatment moves into larger Phase 2 efficacy studies.

This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.

With a target enrollment of 8 participants, this is a small study — typical of early-phase research, rare-disease trials, or pilot studies designed to generate preliminary signal before a larger study is launched.

Who May Be Eligible (Plain English)

Who May Qualify: 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 willing to sign a consent form 2. Capable of and willing to provide signed willing to sign a consent form 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.

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 Always talk to your doctor about whether this trial is right for you.

How to Talk to Your Doctor About This Trial

Bring the printable summary of this trial — including the NCT ID (NCT07137338), the sponsor (Rocket Pharmaceuticals INC.), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.

Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?
