Summary

This trial tests a new gene therapy for people with a type of heart failure where the heart struggles to relax and fill with blood. The therapy is given through an infusion directly into the heart. Researchers want to see if it helps the heart work better and if it is safe for patients. Gene therapy has shown promise in treating heart failure, with improvements making it safer and more effective.

Who is the study for?
This trial is for adults with heart failure who still have a good amount of pumping function (ejection fraction ≥ 50%) and symptoms that are not the most severe. They should be able to exercise somewhat, take diuretics, and use birth control if needed. People with severe lung disease, extreme obesity, unstable conditions, major organ dysfunction or specific heart diseases like amyloidosis can't join.
What is being tested?
The study tests a one-time gene therapy infusion called AAV1/SERCA2a to see if it's safe and can help the heart fill better during relaxation. Participants will receive this treatment in a special lab setting and then be monitored closely for one year with follow-ups over phone calls for four more years.
What are the potential side effects?
Potential side effects may include reactions at the infusion site or allergic responses due to the body's reaction to the new gene material. Since it involves genetic therapy, there might also be unforeseen risks related to altering genes within heart muscle cells.

Other Research
Gene therapy for heart failure, such as the one being studied to improve ventricular relaxation, works by modifying genetic material to enhance the function of proteins involved in cardiac muscle contraction and relaxation. This can help the heart fill more effectively during diastole, improving overall cardiac function. Other common treatments include inotropes, which increase the force of heart contractions, and vasodilators, which reduce the resistance the heart must pump against, thereby improving blood flow and reducing the heart's workload. Mechanical support devices, like ventricular assist devices, can take over some of the heart's pumping function, providing relief to the failing heart. These treatments are crucial for heart failure patients as they aim to improve symptoms, enhance quality of life, and reduce the risk of hospitalization and mortality.
