OrbusNeich’s COMBO™ Dual Therapy Stent Demonstrates Non-inferiority vs the Market Leading XIENCE™ Everolimus Eluting Stent

New results from the HARMONEE Japan/US Registration Trial, reported by OrbusNeich today in the First Report Investigations session at the 29th annual Transcatheter Cardiovascular Therapeutics (TCT) scientific symposium, demonstrate that the COMBO™ Dual Therapy Stent (DTS) compares favorably to the market leading option for treating patients with significant ischemic heart disease.

The Japan-United States of America Harmonized Assessment by Randomized Multicenter Study of OrbusNEich’s COMBO Stent (HARMONEE) is a pivotal (Shonin, Japan) registration study being conducted to demonstrate the effectiveness of the combined endothelial progenitor cell capture and drug-eluting stent (COMBO) compared to the Abbott Vascular Xience stent in patients with ischemic coronary disease and non-ST-elevation acute coronary syndrome. The results showed that the overall incidence of the primary endpoint target vessel failure (TVF) was lower than the original estimated 9.0%, with 7.0% in the COMBO group vs 4.2% in the Xience group at 12 months, thereby meeting the non-inferiority requirement (P=0.020).[1]

“Achieving non-inferiority in TVF compared to the best-in-class current DES, with the addition of superior surrogate measures of site healing by COMBO in this randomized study, represents the opening of an exciting new chapter in percutaneous coronary intervention device design targeting enhanced safety and effectiveness for patients with coronary artery disease,” said Principal Investigator Mitchell Krucoff, MD, PhD, Professor of Cardiology, Duke University Medical Center and Duke Clinical Research Institute, Durham, NC, USA.

Kaplan-Meier curves revealed that target vessel revascularization (TVR) events driven by the 1-year protocol re-catheterization were notable in both stent groups, despite the use of fractional flow reserve (FFR) to mitigate such event ‘spikes’. The TVF odds ratio of COMBO versus imputed bare-metal stent (BMS) was 0.673 and did not meet the pre-specified assay sensitivity, but the comparison was underpowered due to the low TVF rates (4.2% vs predicted 9%). COMBO was superior to imputed BMS with respect to angiographic in stent (P<0.001) and in segment late loss (P=0.003) at 12 months.

An independent quantitative coronary arteriography core laboratory reported in stent late loss at 1 year of COMBO vs Xience of 0.293 mm vs 0.219 mm and in segment late loss of 0.229 mm vs 0.220 mm respectively. Additionally, the angiographic in stent restenosis of COMBO vs Xience was 1.3% vs 2.6% and in segment restenosis was 2.5% vs 3.9%.

Optical Coherence Tomography (OCT) at 12 months revealed significantly better healthy tissue strut coverage (thickness >40 micron in patients with normal FFR) with COMBO vs Xience (91.56% vs 74.82%; P<0.001). Also, the qualitative appraisal of the neointima showed more homogeneous tissue with COMBO vs Xience (81.2% vs 68.8%). “OCT observations suggest an active mechanistic role of EPC technology including superior healthy tissue strut coverage with COMBO vs the Everolimus Eluting Stent, and more qualitatively homogeneous neointimal tissue with COMBO,” said Mitchell Krucoff.

The results from HARMONEE build further compelling evidence for COMBO and help to support OrbusNeich’s planned application for approval in Japan and to meet the feasibility trial requirements in the US.
