High Risk Patients4
CeloNova BioSciences’ comprehensive clinical program consists of approximately 3,300 patients worldwide, including over 2,400 being evaluated with the 2nd generation PzF NanoCoated stent, COBRA PzF NCS.
COBRA REDUCE is the world’s first and only randomized, global study designed to assess clinical outcomes in high bleeding risk patients with 14-day DAPT as compared to FDA-approved DES with 3 or 6-months of DAPT.§
