New study tracks rare genetic heart condition to guide future treatments
NCT ID NCT05981092
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows about 35 people with dilated cardiomyopathy caused by a BAG3 gene mutation, a condition that weakens the heart muscle. Over three years, researchers will monitor heart function, symptoms, and quality of life using tests like imaging and blood work. The goal is to understand how the disease progresses naturally, which could help design better treatments in the future.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help researchers better understand BAG3-related heart disease and design future treatments.
- What could go wrong
- This is an observational study with only 35 participants, so findings may not apply to everyone. It does not test any new treatment.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Documented BAG3 mutation that causes or is likely to cause dilated cardiomyopathy * Heart failure Stage B-D, New York Heart Association (NYHA) Class I-IV * Left Ventricular Ejection Fraction ≤50% (i.e., Reduced Heart Function) Exclusion Criteria: * Acute decompensated heart failure within 1 month prior to enrollment.(such as hospitalization) * Any of the following within 3 months prior to screening: myocardial infarction (MI), cardiac surgical procedures (other than for pacemaker/ICD/CRT-defibrillator \[CRT-D\] implantation), acute coronary syndrome, or hospitalization for cardiac arrhythmia. * History of heart transplantation * eGFR \<30 mL/min/1.73 m2 (significantly impaired kidney function) * Noncardiac condition that limits lifespan to \<1 year. * Presence of other form(s) of cardiomyopathy contributing to heart failure * Previous administration with an investigational drug within 30 days (or as determined by the local requirement). * No more than 3 first-degree members of the same family who are already participating in the study
