What is the purpose of this trial?

This trial tests a new treatment called the CardiAMP cell therapy system, which uses special cells from a participant's own bone marrow to aid those with heart failure caused by past heart attacks. The trial aims to determine if this treatment is safe and effective in improving heart function. Participants will either receive the cell therapy or undergo a similar procedure without it. This trial suits individuals who have experienced heart failure symptoms for some time, specifically with reduced heart function due to past heart attacks, and are already on stable treatment plans. As an unphased trial, it offers a unique opportunity to contribute to groundbreaking research that could lead to new heart failure treatments.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop your current medications, but it requires that you have been on stable heart failure therapy for at least three months before joining. It's best to discuss your specific medications with the trial team.

What prior data suggests that the CardiAMP cell therapy system is safe for patients with ischemic heart failure?

Research has shown that the CardiAMP cell therapy system has promising safety results from past studies. No major safety issues have emerged, reassuring those considering participation in a clinical trial for this treatment. The therapy uses a patient's own bone marrow cells, potentially reducing risks often linked to foreign substances. Some studies suggest that this treatment might lower early death rates and hospital readmissions for heart failure. Overall, the safety findings are encouraging. ^{1 2 3 4 5}

Why are researchers excited about this trial?

CardiAMP cell therapy is unique because it uses a patient's own bone marrow cells to potentially repair heart tissue damaged by heart failure. Unlike traditional treatments that typically manage symptoms or slow disease progression, CardiAMP directly targets the heart muscle itself by delivering these autologous cells via a catheter into the heart. This approach could lead to improved heart function and quality of life. Researchers are excited about CardiAMP because it represents a shift from symptom management to actual tissue regeneration, offering hope for more effective long-term outcomes in heart failure patients.

What evidence suggests that the CardiAMP cell therapy system might be an effective treatment for heart failure?

Research has shown that the CardiAMP cell therapy system, which trial participants may receive, might help treat ischemic heart failure. This treatment uses a patient's own bone marrow cells and could lower the risk of early death and reduce the likelihood of rehospitalization due to heart failure. Encouraging signs indicate that it may improve both survival and quality of life for patients with this condition. Importantly, no major safety issues have been reported so far. These findings suggest that CardiAMP cell therapy could be a promising option for heart failure patients. ^{1 2 3 4 6}

Autologous bone marrow cell transplantation shows significant benefits for patients with chronic coronary artery disease, including improved heart function, reduced infarct size, and enhanced physical ability, with no observed side effects.

The therapy works through multiple mechanisms, such as direct differentiation into heart cells and stimulation of existing cardiac stem cells, making it a promising option for heart tissue regeneration after myocardial infarction.

Cardiac transplantation is the only definitive treatment for end-stage heart failure, but due to organ shortages, patients often face long waiting periods that may require temporary circulatory support.

Emerging treatments like autologous skeletal myoblast transplantation show promise based on experimental data, but their clinical benefits need further validation through randomized trials.

Cardiac cell therapy, which involves injecting stem cells to restore heart function, has been shown to be safe and has produced encouraging efficacy results in treating chronic heart failure and acute myocardial infarction.

Key challenges remain in optimizing this therapy, including preventing cell migration, increasing cell survival, and improving integration of the injected cells into the heart tissue.

Cardiac cell therapy has been shown to be safe and offers encouraging efficacy results in restoring heart function for patients with chronic heart failure and acute myocardial infarction.

To maximize the benefits of cardiac cell therapy, it is crucial to address three main challenges: preventing cell migration, increasing cell survival, and enhancing integration into the heart tissue.

The CardiAMP Heart Failure trial demonstrated that personalized marrow-derived cell therapy is feasible and well tolerated in patients with chronic heart failure after a myocardial infarction, with no serious adverse events reported in the initial cohort of 10 patients.

Patients showed significant improvement in their 6-minute walk distance at 6 months (+47.8 m) and trends toward better heart function and quality of life, suggesting potential benefits of this treatment approach for heart failure management.

Interventional heart failure therapies, including mechanical assist devices and heart transplantation, are crucial for treating end-stage refractory heart failure when drug therapies are insufficient.

In the CHART-1 clinical trial involving 249 patients with ischemic heart failure, cardiopoiesis-guided cell therapy showed comparable improvements in health-related quality of life as measured by the Minnesota Living with Heart Failure Questionnaire (MLHFQ) when compared to a sham procedure, although the overall difference was not statistically significant (P = .107).

However, patients with advanced left ventricular enlargement experienced a significant benefit from cell therapy, with a mean treatment difference of -6.4 points on the MLHFQ (P = .009), indicating that this subgroup may particularly benefit from cell therapy in terms of both quality of life and reduced rates of death and hospitalization.

Myocardial cell therapy shows promise for regenerating heart muscle and improving heart function, especially in small animal models, but its success in human patients, particularly the elderly, has been limited.

The challenges in translating cardiac cell therapy from research to clinical practice may be due to the use of autologous cells from older patients, which are affected by aging processes, raising questions about the therapy's effectiveness for this population.

Cell therapy for heart failure has shifted from the idea of replacing dead heart cells to focusing on the beneficial factors that these cells secrete, which help the body repair itself.

Initial clinical trials using various cell sources have not shown clear improvements in heart failure outcomes, but the data collected can help refine future therapies by selecting the best cells and improving how they are delivered to patients.

Cell therapy in heart failure:where do they stand? Menasché, P.[2019]

In a review of 35 clinical trials involving 2,472 patients, the incidence of periprocedural adverse events (AEs) during intracoronary cell transplantation for myocardial infarction (MI) was found to be 7.5%, while granulocyte colony-stimulating factor (GCS-F) administration for cell mobilization had a higher incidence of 16%.

For ischemic cardiomyopathy (iCMP), periprocedural AEs were much less common at 2.6%, suggesting that the method of cell therapy administration significantly impacts safety, and that avoiding the intracoronary route may reduce the risk of AEs.
