Study Points to Short DAPT with COBRA PzF™ Coronary Stent

It’s the GRCI French Cardiology Meeting in Paris this week, an event that sees CeloNova BioSciences, Inc., proclaiming results from a First-in-Man (FIM) clinical trial of its COBRA PzF™ coronary stent system.


Texas-based cardio device company CeloNova’s claims its COBRA PzF™ coronary stent system employs a advanced nano-thin coating of Polyzene™-F polymer that is thrombo-resistant, promotes rapid endothelialization and results in lowering of late loss. The result ought to be a reduced need for extended Dual Antiplatelet therapy (DAPT)

Results of “First-in-man expérience avec le stent Cobra-PzF, utilisant un nano-coating,” were presented by Luc Maillard, MD PhD, at the prestigious French Cardiology Meeting, GRCI, held in Paris, France. Dr. Maillard concluded that the system can be a safe and effective interventional treatment for real-world and complex patients with heart disease.

The prospective, single-center study included 100 patients, many of whom presented with multi-vessel disease, complex lesions, and co-morbidities such as diabetes, hypertension, dyslipidemia, atrial fibrillation, history of PCI, previous myocardial infarction, and more. At six-month follow-up, results showed zero-percent (0%) stent thrombosis, zero-percent (0%) myocardial infarctions, one cardiac death due to terminal cardiac insufficiency (1%), and three-percent (3%) Target Lesion Revascularization (TLR), leading to four-percent (4%) Major Adverse Coronary Event (MACE).

Investigator comments

“The COBRA PzF coronary stent system’s six-month clinical performance is impressive given the wide variety of challenging patients in this study. Even more remarkable are the low TLR and MACE rates as well as the absence of major bleeding complications related to the 30-day limit on dual-antiplatelet therapy,” said Dr. Maillard. “These data add to recent animal studies showing that the COBRA PzF stent and its nanocoating technology is associated with rapid healing and re-endothelialization, and may reduce stent thrombosis and restenosis without the use of long-term blood thinning medication.”

Company comments

“The COBRA PzF coronary stent is designed to satisfy the unmet market need for a device that offers the short dual-antiplatelet therapy regimen associated with bare-metal stents, but with the possibility of lower restenosis rates,” said Kathryn Conner, Senior Vice President, Strategic Marketing, CeloNova. “CeloNova will continue to support the growing body of compelling clinical evidence for this exciting stent platform.”
