CeloNova Enrolls First Patient in COBRA REDUCE Trial for Patients at High Risk of Bleeding

CeloNova BioSciences, Inc. (CeloNova) announced today that the first patient has been enrolled in its highly anticipated COBRA REDUCE trial. The COBRA REDUCE trial recently received conditional FDA approval and will study the COBRA PzF^TM nanocoated coronary stent (NCS) system in patients at high risk of bleeding.

The first stent in the trial was implanted at the Northshore University Hospital, New York by Loukas Boutis, MD. Eventually, 844 patients will be enrolled in the clinical trial both in the U.S. and Europe.

Rajiv Jauhar, MD, Chief of Cardiology and Director Cardiac Catheterization Labs at the Northshore University Hospital in New York, said, “We are excited to be part of this second, very important, trial with the COBRA PzF stent. We were the highest enrolling center in the initial PzF SHIELD trial with the COBRA PzF stent and hope to repeat our achievement.”

About one in five patients are at high risk of bleeding after stenting. Complications from bleeding after PCI occur more frequently than myocardial infarctions and have a greater impact on mortality.¹ The trial will evaluate if the COBRA PzF stent, with its novel Polyzene™-F nanocoating and advanced thin-strut design, can help reduce bleeding as compared to drug eluting stents (DES), by shortening the duration of dual antiplatelet therapy (DAPT) to 14 days in patients treated with oral anticoagulation and undergoing PCI.

“For patients with high risk of bleeding such as those on triple therapy, the optimal duration of DAPT and type of stent are important questions,” said Adnan Kastrati, MD, Professor of Medicine at Deutsches Herzzentrum, München, Germany and the Principal Investigator of the trial.

”If the COBRA PzF stent, with its novel nanocoating, is able to reduce the duration of DAPT to only two weeks and to reduce bleeding, while maintaining parity with DES in thrombosis and restenosis, it could be a very compelling new treatment option.”

The COBRA REDUCE trial is the second major interventional cardiology trial for CeloNova and follows a successful early enrollment completion of the PzF SHIELD IDE study last year. Positive results from the PzF SHIELD study will allow the company to complete its PMA application to the FDA for the COBRA PzF stent. These trials are part of a comprehensive clinical program studying over 2000 patients worldwide. Previous peer-reviewed studies with over 700 patients implanted with the prior generation stent coated with the Polyzene-F nanocoating demonstrated low TLR and no stent thrombosis.

The COBRA PzF stent has thin struts made of Cobalt Chromium Super Alloy and is coated with an advanced Polyzene-F nanocoating, which may reduce fibrinogen and platelet adhesion as shown in preclinical studies. Furthermore, the stent platform is designed to minimize vessel wall injury and lower inflammation as demonstrated in preclinical studies.

“The COBRA PzF stent is designed to satisfy the unmet market need for a device that reduces the need for long-term blood-thinning agents, but with the possibility of lower restenosis rates,” said Martin Landon, President and CEO, CeloNova Biosciences, Inc. "This study is another major milestone in providing compelling clinical evidence. With the enrollment of the first patient in this randomized trial, led by Professor Kastrati, one of the leading researchers in the world, we have taken a very important next step in demonstrating the positive patient benefits of our technology."

The COBRA PzF coronary stent system is an investigational device in the United States. The COBRA PzF coronary stent system received CE Mark approval in 2012 and launched in Europe and the Middle East in 2013.
