Amphilimus- vs. zotarolimus-eluting stents in patients with diabetes mellitus and coronary artery disease: the SUGAR trial

Aim: Patients with diabetes mellitus are at high risk of adverse events after percutaneous revascularization, with no differences in outcomes between most contemporary drug-eluting stents. The Cre8 EVO stent releases a formulation of sirolimus with an amphiphilic carrier from laser-dug wells, and has shown clinical benefits in diabetes. We aimed to compare Cre8 EVO stents to Resolute Onyx stents (a contemporary polymer-based zotarolimus-eluting stent) in patients with diabetes. Methods and results: We did an investigator-initiated, randomized, controlled, assessor-blinded trial at 23 sites in Spain. Eligible patients had diabetes and required percutaneous coronary intervention. A total of 1175 patients were randomly assigned (1:1) to receive Cre8 EVO or Resolute Onyx stents. The primary endpoint was target-lesion failure, defined as a composite of cardiac death, target-vessel myocardial infarction, and clinically indicated target-lesion revascularization at 1-year follow-up. The trial had a non-inferiority design with a 4% margin for the primary endpoint. A superiority analysis was planned if non-inferiority was confirmed. There were 106 primary events, 42 (7.2%) in the Cre8 EVO group and 64 (10.9%) in the Resolute Onyx group [hazard ratio (HR) 0.65, 95% confidence interval (CI) 0.44 to 0.96; pnon-inferiority <0.001; psuperiority = 0.030]. Among the secondary endpoints, Cre8 EVO stents had significantly lower rate than Resolute Onyx stents of target-vessel failure (7.5% vs 11.1%, HR 0.67, 95% CI 0.46 to 0.99; p = 0.042). Probable or definite stent thrombosis and all-cause death were not significantly different between groups. Conclusions: In patients with diabetes, Cre8 EVO stents were non-inferior to Resolute Onyx stents with regard to target-lesion failure composite outcome. An exploratory analysis for superiority at 1 year suggests that the Cre8 EVO stents might be superior to Resolute Onyx stents with regard to the same outcome

A Randomized Comparison of Reservoir-Based Polymer-Free Amphilimus-Eluting Stents Versus Everolimus-Eluting Stents With Durable Polymer in Patients With Diabetes Mellitus: The RESERVOIR Clinical Trial.

OBJECTIVES The aim of this study was to compare the efficacy of amphilimus-eluting stents (AES) with that of everolimus-eluting stents (EES) in patients with diabetes mellitus (DM). BACKGROUND The AES is a polymer-free drug-eluting stent that elutes sirolimus formulated with an amphiphilic carrier from laser-dug wells. This technology could be associated with a high efficacy in patients with DM. METHODS This was a multicenter, randomized, noninferiority trial. Patients with DM medically treated with oral glucose-lowering agents or insulin and de novo coronary lesions were randomized in a 1:1 fashion to AES or EES. The primary endpoint was the neointimal (NI) volume obstruction assessed by optical coherence tomography at 9-month follow-up. RESULTS A total of 116 lesions in 112 patients were randomized. Overall, 40% were insulin-treated patients, with a median HbA1c of 7.3% (interquartile range: 6.7% to 8.0%). The primary endpoint, NI volume obstruction, was 11.97 ± 5.94% for AES versus 16.11 ± 18.18% for EES, meeting the noninferiority criteria (p = 0.0003). Pre-specified subgroup analyses showed a significant interaction between stent type and glycemic control (p = 0.02), with a significant reduction in NI hyperplasia in the AES group in patients with the higher HbA1c (p = 0.03). By quantitative coronary angiography, in-stent late loss was 0.14 ± 0.24 for AES versus 0.24 ± 0.57 mm for EES (p = 0.27), with a larger minimal lumen diameter at follow-up for AES (p = 0.02), mainly driven by 2 cases of occlusive restenosis in the EES group. CONCLUSIONS AES are noninferior to EES for the coronary revascularization of patients with DM. These results suggest a high efficacy of the AES and may support the potential benefit of this stent in patients with DM.

Standard chemotherapy with or without bevacizumab in advanced ovarian cancer: quality-of-life outcomes from the International Collaboration on Ovarian Neoplasms (ICON7) phase 3 randomised trial

BACKGROUND: In the Gynecologic Cancer Intergroup International Collaboration on Ovarian Neoplasms 7 (ICON7) trial, bevacizumab improved progression-free survival in patients with ovarian cancer when used in combination with first-line chemotherapy and as a single-drug continuation treatment for 18 cycles. In a preliminary analysis of a high-risk subset of patients, there was also an improvement in overall survival. This study aims to describe the health-related quality-of-life (QoL) outcomes from ICON7. METHODS: ICON7 is a randomised, multicentre, open-label phase 3 trial. Between Dec 18, 2006, and Feb 16, 2009, after a surgical procedure aiming to debulk the disease, women with International Federation of Gynecology and Obstetrics (FIGO) high-risk stage I–IV epithelial ovarian cancer were randomly allocated (1:1) by computer program and block randomisation to receive either six cycles of standard chemotherapy (total 18 weeks) with carboplatin (area under the curve 5 or 6) and paclitaxel (175 mg/m(2)) alone or with bevacizumab (7·5 mg/kg) given intravenously with chemotherapy and continued as a single drug thereafter (total 54 weeks). The primary QoL endpoint was global QoL from the European Organisation for Research and Treatment of Cancer quality-of-life questionnaire–core 30 at week 54, analysed by ANOVA and adjusted for baseline score. Analyses were by intention to treat. The ICON7 trial has completed recruitment and remains in follow-up. This study is registered, number ISRCTN91273375. FINDINGS: 764 women were randomly assigned to the standard chemotherapy group and 764 to the bevacizumab group. At baseline, 684 (90%) of women in the standard chemotherapy group and 691 (90%) of those in the bevacizumab group had completed QoL questionnaires. At week 54, 502 (66%) women in the bevacizumab group and 388 (51%) women in the standard chemotherapy group provided QoL data. Overall, the mean global QoL score improved during chemotherapy by 7·2 points (SD 24·4) when analysed for all women with data at baseline and week 18. The mean global QoL score at 54 weeks was higher in the standard chemotherapy group than in the bevacizumab group (76·1 [SD 18·2] vs 69·7 [19·1] points; difference 6·4 points, 95% CI 3·7–9·0, p<0·0001). INTERPRETATION: Bevacizumab continuation treatment seems to be associated with a small but clinically significant decrement in QoL compared with standard treatment for women with ovarian cancer. The trade-off between the prolongation of progression-free survival and the quality of that period of time needs to be considered in clinical practice when making treatment decisions.
