简要总结

The overall aim of the project is to test the feasibility and safety of allogeneic adipose-derived stromal cells (CSCC_ASC) investigational medicinal product, to improve myocardial function in patients with non-ischemic dilated cardiomyopathies (NIDCM) and heart failure.

详细描述

Study design

The primary objective of the study is to investigate safety and regenerative capacity of direct intra-myocardial injection of 100 million allogeneic CSCC_ASCs in NIDCM patients with reduced left ventricular EF (≤ 40%) and heart failure.

It is a proof of concept study enrolling a total of 30 NIDCM patients with heart failure who will be randomly allocated in a 2:1 ratio to either CSCC_ASC cell therapy (Stem Cell Group) or no cell therapy (Control Group). The treatment period is estimated to be 6 months (efficacy end-point) with a 12-month follow-up period for safety end-points.

Patient treatment and follow-up

  • The cell IMP will be delivered by a courier service to from REGIONH to UKCL using validated portable dry liquid nitrogen shipping containers. It will then be stored in nitrogen vapour containers until treatment.
  • The preparation of the IMP will be performed as described in the treatment manual. The IMP will be thawed and prepared for injection immediately before treatment.
  • A 3-D map of the left ventricle will be created using the NOGA XP® system (Biological Delivery System, Cordis, Johnson & Johnson, USA). The delivery of the IMP (100 million ASCs) into the myocardium will be performed by 10-15 injections of 0.2 cc, as described in the treatment manual.
  • The post cell therapy surveillance will include clinical and laboratory safety follow-up with monitoring of cardiac enzymes, hemodynamic and rhythm stability. The clinical follow-up will be obtained at pre-defined time points. The presence of allogeneic HLA anti-bodies will be monitored three and six months after treatment. End-points will be monitored continuously and reported as occurring throughout the 12 months follow-up period.
