About this study

Official title: Phase I Study of Cardiac Progenitor Cell Therapy in Patients With Single Ventricle Physiology

Hypoplastic left heart syndrome (HLHS) and related anomalies involved a single ventricle are characterized by hypoplasia of the left heart and the aorta with compromised systemic cardiac output. Infants with the syndrome generally undergo a staged surgical approach in view of an ultimate Fontan procedure. Although long-term survival in patients with HLHS and related single ventricle physiology has improved markedly with advances in medical and surgical therapies, a growing number of infants will ultimately require heart transplantation for end-stage heart failure due to several potential disadvantages include a negative effect on right ventricular function, arrhythmia, additional volume load via regurgitation from the nonvalved shunt, and impaired growth of the pulmonary artery.

Risk factors for poor outcome of heart transplantation with HLHS and single ventricle physiology are older age at transplantation and previous Fontan operation. New strategies are needed to improve the underlying transplant risks proper for the Fontan failure patients.

Emerging evidence suggests that heart-derived stem/progenitor cells can be used to improved cardiac function in patients with ischemic heart disease. In this trial, the investigators aimed to test the safety and feasibility of intracoronary injection of autologous cardiac progenitor cells in patients with HLHS and related single ventricle anomalies and that could improve ventricular function at 3 months' follow up.

Read the detailed description

Autologous cardiac progenitor cells are isolated from patients' own cardiac tissues obtained during palliative shunt procedure. Patients will receive 0.3 million/kg of autologous cardiac progenitor cells via intracoronary delivery 1 month after cardiac surgery. Follow-up visits 3 months to 1 year after cell injection will need to prospectively verify the clinical, laboratory, and safety-related data.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Feasibility Evaluation and Major Cardiac Adverse Events Related to Transcoronary Infusion of Cardiac Progenitor Cells

    Feasibility was assessed by number of participants discontinued the study due to adverse events or number of participants received unsuccessful cell delivery by study physician. Unsuccessful was defined as failure of coronary selection of guiding catheter or direct cell infusion.

    The primary end point is to monitor major adverse cardiac events include death, sustained/symptomatic ventricular tachycardia, aggravation of heart failure, new myocardial infarction, unplanned cardiovascular operation for cardiac tamponade and infection in the first month after injection, and serially afterwards.

    Measured: 3 months to 1 year after cell transplantation

Secondary outcomes (1)
  1. Serious Adverse Events

    The incidence of hospitalization for heart failure, ventricular arrhythmia, general infection, and renal and hepatic dysfunction by CDC treatment.

    Measured: 3 months to 1 year after cell transplantation

What does the primary outcome measure?

Feasibility Evaluation and Major Cardiac Adverse Events Related to Transcoronary Infusion of Cardiac Progenitor Cells (time frame: 3 months to 1 year after cell transplantation). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01273857, which also lists 8 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
