Phase I Safety and Feasibility Study of Intracoronary Delivery of Autologous Bone Marrow Derived Mononuclear Cells

12. maj 2021 opdateret af: Timothy J Nelson, MD, PhD

Phase I Safety and Feasibility Study of Intracoronary Delivery of Autologous Bone Marrow Derived Mononuclear Cells for Systemic, Single Right Ventricular Failure Due to Congenital Heart Disease

The objective of this study is to determine the safety and feasibility of autologous mononuclear cells (MNC) collected from bone marrow (BM) and intracoronary delivery for individuals with declining performance of their single right ventricle systemic pumps. This procedure has the potential to foster a new strategy for congenital heart patients. This is an open-label study of autologous MNC derived from bone marrow with a 2-year follow-up to document 1) related serious adverse events and 2) monitor changes in cardiac structure and function.

Detaljeret beskrivelse

This study is an open label Phase I trial to determine the safety and feasibility of bone marrow-derived mononuclear cells delivered into the coronary circulation of subjects with Fontan circulation and right ventricular dysfunction. Subjects will be screened at outpatient clinic visits at Mayo Clinic and interested qualified subjects will be consented and offered participation in this trial. Once informed consent has been obtained; preoperative values will be established and a selection committee will review subjects within three days prior to planned procedure to confirm inclusion and exclusion criteria. This will require a non-study cardiologist to review the clinical case and confirm the baseline cardiac function with evidence of disease progression with right ventricle dysfunction. However, individuals with decreased cardiac function requiring inotropic support and immediate listing for cardiac transplantation will NOT be included such that the risk of this research procedure may not be acceptable. Following cell-based product delivery, subjects will be followed for 6-months according to a pre-determined schedule that includes imaging studies along with questionnaires, electrophysiology and laboratory studies. Subjects will be contacted for an additional 18-months for surveillance by phone.
