AIMS: Novolimus, a macrocyclic lactone with anti-proliferative properties, has a similar efficacy to currently available agents; however it requires a lower dose, and less polymer, and is therefore conceivably safer.
METHODS AND RESULTS: The EXCELLA II study was a prospective, multicentre, single-blind, non-inferiority clinical trial which randomised 210 patients with a maximum of two de novo coronary artery lesions in two different epicardial vessels in a ratio of 2:1 to treatment with either the Elixir DESyne Novolimus Eluting Coronary Stent System (NES n=139, Elixir Medical, Sunnyvale, CA, USA) or the Endeavor zotarolimus eluting stent (ZES n=71, Medtronic, Santa Rosa, CA, USA). The primary endpoint was in-stent mean late lumen loss (LLL) at 9-months follow-up. In-stent percent volume obstruction (%VO) was measured in a?sub-group of 65 patients having 9-month intravascular ultrasound (IVUS) follow-up. Clinical secondary endpoints included a device orientated composite of cardiac death, target vessel myocardial infarction (MI), and clinically indicated target lesion revascularisation (CI-TLR) assessed at 9-months follow-up. At 9-months, the in-stent LLL was 0.11+/-0.32 mm in the NES arm, as compared to 0.63+/-0.42 mm in the ZES (p<0.0001 non-inferiority, p<0.0001 superiority). In-stent%VO was 4.5+/-5.1% and 20.9+/-11.3% for NES and ZES, respectively (p<0.001). There was no significant difference between stent groups in the device orientated composite endpoint (NES 2.9% vs. ZES 5.6%, -2.8% [-8.8%, 3.3%], p=0.45) or its individual components of cardiac death, target vessel MI and CI-TLR.
CONCLUSIONS: This non-inferiority randomised study not only met its primary endpoint, but also demonstrated superiority of NES compared to the ZES in terms of in-stent LLL.
