Cardio3 BioSciences Receives Authorization to Begin World’s First Phase III Clinical Trial in Regenerative Medicine for Heart Failure

November 22, 2012

MONT-SAINT-GUIBERT, Belgium, November 22, 2012 /PRNewswire/ –

The Belgian biotechnology company, Cardio3 BioSciences (C3BS), a leader in the
discovery and development of regenerative and protective therapies for the treatment of
cardiac diseases, today announces it has received authorization from the Belgian Federal
Agency for Medicines and Health Products (FAMHP) to begin its Congestive Heart failure
Cardiopoietic Regenerative Therapy (CHART-1) European Phase III trial for C3BS-CQR-1 in
Belgium. This represents a world premiere for a regenerative medicine product targeting
heart failure to be tested in the context of a Phase III trial. C3BS-CQR-1 is an
autologous stem cell therapy for heart failure.

The Phase III trial is a prospective, multi-centre, randomized, sham-controlled,
patient-and evaluator-blinded study comparing treatment with C3BS-CQR-1 to a sham
treatment. The trial will recruit a minimum of 240 patients with chronic advanced
symptomatic heart failure. The primary endpoint of the trial is a composite endpoint
including mortality, morbidity, quality of life, Six Minute Walk Test and left ventricular
structure and function at 9 months post-procedure.

Studies in additional countries will commence once national regulatory approvals have
been received.

The Cardio3 BioSciences therapy, called C3BS-CQR-1, involves taking stem cells from a
patient’s own bone marrow and through a proprietary process called Cardiopoiesis,
re-programming those cells so that they go onto becoming heart cells. The cells, known as
cardiopoietic cells, are then injected back into the patient’s heart through a minimally
invasive procedure using a catheter called C-Cathez(R), with the aim of repairing damaged
tissue and improving heart function and patient clinical outcomes. C3BS-CQR-1 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). This Phase III trial builds on the successful outcome of the Phase II
trial conducted between 2009 and 2010 in multiple clinical sites in Belgium, Serbia and
Switzerland.

Dr Christian Homsy, CEO of Cardio3 BioSciences, said: “Heart failure remains a
significant unmet clinical need associated with high morbidity, mortality and escalating
healthcare costs. We believe C3BS-CQR-1 has a potential to become an alternative to heart
transplantation which is the only curative treatment for heart failure available today.
Our Phase III trial is the first to begin anywhere in the world for a regenerative therapy
for this indication. We look forward to confirming the promising results we have already
seen in our Phase II study.”

Dr Jozef Bartunek, Principal Investigator, added: “Regenerative therapies have the
potential to revolutionize the treatment of heart disease and other conditions and we are
excited to be working with Cardio3 BioSciences on what is a ground breaking study. The
results seen in the earlier trials were encouraging and if repeated in this larger study
would bring nearer a potentially disruptive treatment for the expanding epidemic of heart
failure.”

Cardio3 BioSciences has completed a Phase II trial with C3BS-CQR-1, which demonstrated
that heart failure patients improved heart function and exercise capacity following
treatment compared to patients receiving current standard of care. Moreover, feasibility
and safety of the C3BS-CQR-1 treatment regimen were established.

About Cardio3 BioSciences

Cardio3 BioSciences is a Belgian leading biotechnology company focused on the
discovery and development of regenerative and protective therapies for the treatment of
cardiac diseases. The company was founded in 2007 and is based in the Walloon region of
Belgium. Cardio3 BioSciences leverages research collaborations in the US and in Europe
with Mayo Clinic and the Cardiovascular Centre Aalst, Belgium.

The Company’s lead product candidate C3BS-CQR-1 is an innovative pharmaceutical
product that is being developed for heart failure indication. C3BS-CQR-1 consists of a
patient’s own cells that are harvested from the patient’s bone marrow and engineered to
become new heart muscle cells that behave identically to those lost to heart disease. This
process is known as Cardiopoiesis.

Cardio3 BioSciences has also developed C-Cath(R)ez, the most technologically injection
catheter with superior efficiency of delivery of bio therapeutic agents into the
myocardium.
