PRESS RELEASE 26 NOVEMBER 2014 10 :00 AM CET CARDIO3 BIOSCIENCES ANNOUNCES THE NOMINATION OF THREE CO-PRINCIPAL INVESTIGATORS FOR ITS CHART-2 PHASE III CLINICAL TRIAL OF C-CURE® FOR THE TREATMENT OF HEART FAILURE

Dr Bernard J. Gersh, Dr Thomas Povsic and Dr Gerasimos Filippatos will be Co- Principal Investigators of the phase III clinical trial CHART-2, authorized by the FDA in January

CHART-2 is expected to start by the end of 2014

Mont-Saint-Guibert, Belgium - Cardio3 BioSciences (C3BS) (Euronext Brussels and Paris: CARD), a leader in the discovery and development of regenerative, protective and reconstructive therapies, announces today the appointment of its three Co-Principal Investigators for the CHART-2 study (Congestive Heart Failure cArdiopoietic Regenerative Therapy), authorized in the United States by the FDA in January, and anticipated to start by the end of 2014.

CHART-2 is Cardio3 BioSciences' second Phase III trial for C-Cure®, the first and only stem cell therapeutic using guided stem cells for the condition of congestive heart failure. C-Cure® is currently in a Phase III clinical trial in Europe (CHART-1). The CHART-2 Phase III trial is a prospective, multi- centre, randomized, sham-controlled, patient- and evaluator-blinded study comparing treatment with C-Cure® to a sham treatment. The trial is designed to recruit a minimum of 240 patients with chronic advanced symptomatic heart failure.
In a clinical trial, the Principal Investigator ("PI") is responsible for the scientific and medical supervision of the trial. The PI reviews the protocol, oversees the implementation of the trial at all the investigational sites, and provides guidance as to the integrity and the interpretability of the data generated during the trial.
Dr Christian Homsy, CEO of Cardio3 BioSciences, said: "Cardio3 BioSciences is very proud to count three such prominent physicians as the Co-Principal Investigators of its phase III clinical study for C-Cure® authorized in the United States. The medical community is eagerly waiting for a solution for the treatment of heart failure patients, and CHART-2 is a promising avenue towards treating this disease. We selected three prominent cardiologists with established reputations and their acceptance to lead our clinical trial is further recognition of the potential of C-Cure® as future treatment of heart failure."

About CHART-2

CHART-2, the Company's second Phase III clinical trial, is intended to assess in the US, the efficacy of C-Cure® as a treatment for heart failure of ischemic origin. CHART-2 is designed as a prospective, multi-centre, randomized, sham-controlled, patient- and evaluator-blinded study comparing treatment with C-Cure® to a sham treatment. The trial is aimed to recruit a minimum of 240 patients with chronic advanced symptomatic heart failure. The primary endpoint of the trial is the Six Minute Walk Test post-procedure, a commonly used index of cardiovascular performance.

About C-Cure®

Cardio3 BioSciences' C-Cure® therapy involves taking stem cells from a patient's own bone marrow and through a proprietary process called Cardiopoiesis, re-programming those cells to become heart cells. The cells, known as cardiopoietic cells, are then injected back into the patient's heart through a minimally invasive procedure, with the aim of repairing damaged tissue and improving heart function and patient clinical outcomes. C-Cure® is the outcome of multiple years of research conducted at Mayo Clinic (Rochester, Minnesota, USA), Cardio3 BioSciences (Mont-Saint-Guibert, Belgium) and Cardiovascular Centre in Aalst (Aalst, Belgium).
