Three-year clinical outcomes of patients treated with everolimus-eluting bioresorbable vascular scaffolds: Final results of the ABSORB EXTEND trial

BACKGROUND: There is still limited data on the very long term clinical outcomes after ABSORB BRS in daily practice. We sought to evaluate the 3 year-performance of the Absorb bioresorbable vascular scaffolds for the treatment of low/moderate complexity patients enrolled in the ABSORB EXTEND trial. METHODS: ABSORB EXTEND is a prospective, single-arm, open-label clinical study in which 812 patients were enrolled at 56 sites. This study allowed the treatment of lesions ≤28 mm in length and reference vessel diameter of 2.0-3.8 mm (as assessed by on-line QCA). To determine the independent predictors of MACE, a multivariable logistic regression model was built using a stepwise (forward/backward) procedure. RESULTS: Average population age was 61 years and 26.5% had diabetes. Most patients had single target lesion (92.4%). Adequate scaffold deployment (PSP) was achieved in 14.2% of the cases. At three years, the composite endpoints of MACE and ischemia-driven target vessel failure were 9.2% and 10.6%, respectively. The cumulative rate of ARC definite/probable thrombosis was 2.2%, with 1.2% of the cases occurring after the 1st year. Independent predictors of MACE were hypertension and the need for "bail out" stent. CONCLUSION: At three-year follow-up, the use of ABSORB in low/moderate complex PCI was associated with low and acceptable rates of major adverse clinical events, despite the infrequent use of the recommended contemporary scaffold deployment technique. However, scaffold thrombosis rate was higher than reported with current generation of metallic DES. (AU)

One-year clinical outcomes of patients treated with everolimus-eluting bioresorbable vascular scaffolds versus everolimus-eluting metallic stents: a propensity score comparison of patients enrolled in the ABSORB EXTEND and SPIRIT trials.

AIMS: We sought to compare the outcomes of low/moderate complexity patients treated with the Absorb BVS from the ABSORB EXTEND trial with patients treated with the XIENCE everolimus-eluting stent (EES), using propensity score (PS) matching of pooled data from the SPIRIT trials (SPIRIT II, SPIRIT III, SPIRIT IV) and the XIENCE V USA trial. METHODS AND RESULTS: ABSORB EXTEND was a prospective, single-arm, open-label clinical study in which 812 patients were enrolled at 56 sites. This study allowed the treatment of lesions ≤28 mm in length and with a reference vessel diameter of 2.0-3.8 mm (as assessed by online QCA). The propensity score was obtained by fitting a logistic regression model with the cohort indicator as the binary outcome and other variables as the predictor variables. At one-year clinical follow-up, there was no statistical difference between groups with regard to MACE (5.0% vs. 4.8%, p=0.83), target lesion failure (5.0% vs. 4.7%, p=0.74), ischaemia-driven target vessel revascularisation (2.3% vs. 3.0%, p=0.38) and device thrombosis (1.0% vs. 0.3%, p=0.11). Myocardial infarction was higher with Absorb (3.3% vs. 1.5%, p=0.02), at the expense of periprocedural CK-MB elevation. Independent predictors of MACE among patients receiving Absorb BVS were treatment of multivessel disease, insulin-dependent diabetes and performance of post-dilation. CONCLUSIONS: At one-year follow-up, propensity score-matched analysis demonstrated that the clinical safety and effectiveness of Absorb are comparable to those of XIENCE EES among non-complex patients treated with PCI.

The ABSORB EXTEND study: preliminary report of the twelve-month clinical outcomes in the first 512 patients enrolled.

AIMS: The safety and performance of the Absorb Bioresorbable Vascular Scaffold (Absorb BVS) system (Abbott Vascular, Santa Clara, CA, USA) has been previously established in 131 patients from cohort A and cohort B of the first-in-man ABSORB trial. Following this trial, ABSORB EXTEND was initiated as a global continued access study (outside of the USA) to expand experience with the Absorb BVS system to different geographies with broader inclusion criteria to include the treatment of longer lesions and multiple vessels. We report in this manuscript the twelve-month clinical outcomes of the first 512 patients in this population. METHODS AND RESULTS: ABSORB EXTEND is a prospective, single-arm, open-label clinical study which will enrol up to 800 patients at up to 100 sites. Included are patients with lesions ≤28 mm in length and reference vessel diameter of 2.0-3.8 mm (as assessed by on-line QCA or IVUS). Treatment of a maximum of two de novo native coronary artery lesions is permitted when each lesion is located in a different epicardial vessel. An independent clinical events committee adjudicates all endpoint-related events. At one year, for the first 512 patients enrolled in the study, the composite endpoints of ischaemia-driven MACE and ischaemia-driven target vessel failure were 4.3% and 4.9%, respectively. The cumulative rate of ARC defined definite and probable scaffold thrombosis for this population was 0.8% at one year. CONCLUSIONS: This interim analysis of the ABSORB EXTEND study shows low rates of MACE and scaffold thrombosis. The study is registered on clinicaltrials.gov (unique identifier NCT01023789).

Three-year data from the XIENCE V INDIA study: safety and efficacy of XIENCE V in 1000 real world Indian patients.

BACKGROUND: Cardiovascular disease in Asia has reached epidemic proportions in recent years. Use of drug eluting stents in Asians has rapidly expanded with varying penetration rates across different countries. The XIENCE V INDIA Study included 'real world' patients who underwent XIENCE V stent implantation to assess short and intermediate term outcomes in Indian patients with diverse risk factors. OBJECTIVE: To evaluate 3-year clinical outcomes in a cohort of 'real world' Indian patients with CAD being treated with XIENCE V Everolimus Eluting Coronary Stent System. METHODS: 1000 patients were enrolled from 18 sites in India between June 2008 and March 2009. Patients were included if their index procedures were completed using only XIENCE V. There were no clinical or angiographic exclusions. An independent Clinical Events Committee adjudicated all endpoint-related events. The primary endpoint was stent thrombosis rate annually through to 3 years as defined by the Academic Research Consortium criteria. The co-primary endpoint was the composite rate of cardiac death and myocardial infarction at 1 year. RESULTS: At 1-year the primary endpoint of definite/probable stent thrombosis rate was 0.51%. No additional very late stent thrombosis was reported through a 3-year follow up. The composite endpoint of cardiac death and any myocardial infarction was 1.9%, 2.7% and 3.1% at 1, 2 and 3 years respectively. CONCLUSION: Despite the high risk population of coronary artery disease, the use of XIENCE V in 'real world' Indian patients was associated with very low clinical event rates upto three years of follow up.

Incidence, time course and predictors of early vs. late target lesion revascularisation after everolimus-eluting stent implantation: a SPIRIT V substudy.

AIMS: To evaluate the incidence, time course and predictors of late target lesion revascularisation (TLR) (between one and two years) as compared to early TLR (<1 year) following everolimus-eluting stent implantation in patients enrolled in the SPIRIT V study. METHODS AND RESULTS: The SPIRIT V single-arm study enrolled a total of 2,700 patients (n=2,663 intent-to-treat) with de novo coronary artery lesions undergoing EES implantation. Patients were evaluated at 30 days, one year and two years following the index procedure. All patients who had a clinically driven TLR (not associated with stent thrombosis) were allocated to either the early or the late group. Clinical, angiographic and procedural data were recorded and predictors of early vs. late TLR were assessed by logistic regression analysis. There were no significant differences in baseline demographics and risk factors between the two groups with the exception that patients in the late TLR group were significantly older (68.5 ± 8.5 years vs. 63.5 ± 8.9 years, p=0.022). At two years, only 2.7% (70/2,562) experienced a TLR unrelated to a stent thrombosis event with 1.6% (43/2,627) occurring within one year of the index procedure and 1.1% (27/2,562) occurring between one and two years. There were no differences between the groups in terms of clinical outcomes. Age ≥70 years was the only variable which independently predicted late TLR (OR=4.80 [1.69-13.63], p=0.0032). CONCLUSIONS: In this large registry without angiographic follow-up, early (<1 year) and late (>1 year) TLR rates were exceedingly low and thereby confirm the previous findings of randomised controlled studies. Age (>70 years) emerged as the only predictor of late TLR.

Two-year outcomes after deployment of XIENCE V everolimus-eluting stents in patients undergoing percutaneous coronary intervention of bifurcation lesions: a report from the SPIRIT V single arm study.

The aim of this analysis was to analyze outcomes of patients undergoing Xience V EES treatment of bifurcation lesions, a subset in which treatment is particularly challenging. The SPIRIT V Study provided an evaluation of the Xience V everolimus eluting stent (EES) performance in complex patient and lesion population. The SPIRIT V Single Arm Study enrolled 2700 patients with de novo coronary artery lesions suitable to be optimally treated with a maximum of four planned Xience V EES. Lesion evaluation was by visual assessment. The outcomes of the 492 patients undergoing Xience V EES stenting of ≥1 bifurcation lesion were compared to those with no bifurcation lesion treated. Compared to those without bifurcation treatment, patients with bifurcation treatment were more likely to have multi-vessel disease (49% vs 40%), left main treatment (3.1% vs 0.9%), more lesions treated (1.5 vs 1.3), calcification (36.4% vs 27.5%), and ostial (17.1% vs 8.2%) and angulated lesions (29.3% vs 21.1%), all P < 0.001. The 30-day composite rate of death, myocardial infarction (MI), target vessel revascularization (TVR) was 4.3% in patients with bifurcation PCI and 2.2% in those with non-bifurcation PCI (P = 0.017). At 2 years, this composite event rate was 11.3% and 10.0% in these two groups, respectively (P = 0.403). Rates of cardiac death, MI, target lesion revascularization (TLR), TVR, and ARC defined definite or probable stent thrombosis (0.4% vs 0.9%, P = 0.402) were not significantly different between the two groups. Despite greater patient and lesion complexity, treatment of patients with bifurcation lesions using the Xience V EES in the SPIRIT V prospective Single Arm Study was safe and effective, with low overall event rates that were similar to those without bifurcation lesion treatment. © 2013 Wiley Periodicals, Inc.

SPIRIT Women, evaluation of the safety and efficacy of the XIENCE V everolimus-eluting stent system in female patients: referral time for coronary intervention and 2-year clinical outcomes.

AIMS: SPIRIT Women is the first interventional trial dedicated exclusively to women, focusing on symptoms at presentation, referral time to coronary intervention and the safety and performance of the XIENCE V stent. METHODS AND RESULTS: SPIRIT Women is a prospective, open-label, multicentre study in which 1,573 women were enrolled at 73 sites outside the United States. The primary endpoint is the composite of all death, Academic Research Consortium (ARC) defined myocardial infarction (MI) and target vessel revascularisation (TVR) at one year. Data collected included symptoms at presentation and referral to coronary intervention. To allow comparison by gender, the latter were compared to data from male patients from the SPIRIT V study. The one- and two-year composite of all death, MI and TVR was 12% and 15%, respectively. Target lesion revascularisation (TLR) and stent thrombosis (definite and probable) rates were 2.4% and 0.59%, respectively, at one year and 3.6% and 0.73%, at two years. The total referral time for coronary intervention in women was four days longer than for men in the SPIRIT V study. CONCLUSIONS: The XIENCE V stent is safe and effective with low TLR and stent thrombosis rates. More efforts remain to be made to increase the awareness of women and physicians of the risk for coronary artery disease (CAD).

The SPIRIT V diabetic study: a randomized clinical evaluation of the XIENCE V everolimus-eluting stent vs the TAXUS Liberté paclitaxel-eluting stent in diabetic patients with de novo coronary artery lesions.

BACKGROUND: Diabetic patients respond less favorably to revascularization and have poorer long-term outcomes. Our main aim was to evaluate the angiographic efficacy of XIENCE V (everolimus-eluting stent, or EES) in diabetic patients compared with TAXUS Liberté (paclitaxel-eluting stent, or PES). METHODS: The SPIRIT V Diabetic Study was a prospective, single-blind, randomized study that enrolled 324 diabetic (insulin and non-insulin dependent) patients at 28 sites in Europe and Asia Pacific. Randomization was 2:1 between EES (n = 218) and PES (n = 106). The primary end point was sequential noninferiority and superiority of EES for in-stent late loss at 9 months. Secondary clinical end points included stent thrombosis, death, myocardial infarction, and revascularization rates up to 1 year. RESULTS: Everolimus-eluting stent was superior to PES for in-stent late loss at 9 months (0.19 mm vs 0.39 mm, respectively; P(superiority) = .0001). The composite rate of death, myocardial infarction, and target vessel revascularization was the same in the 2 groups at 1 year (16.3% vs 16.4%). No stent thromboses (Academic Research Consortium definite and probable) were seen through 1 year with EES compared with 2 of 104 (2%) with PES (P = .11). CONCLUSION: In this prospective, randomized trial in a high-risk group of diabetic patients, implantation of EES compared with PES resulted in significantly better inhibition of intimal hyperplasia with a comparable safety outcome.

Avaliação do stent coronário eluidor de everolimus XIENCE TM V na cpopulação feminina latino-americana do estudo de braço único SPIRIT Women: acompanhamento clínico de um ano / Evaluation of the XIENCE TM V everolimus-eluting coronary stent system in the female latin american population of the SPIRIT Women single-arm study: one-year clinical follow-up data

INTRODUÇÃO: Os estudos com stents farmacológicos têm avaliado predominantemente populações masculinas de descendência europeia. O estudo de braço único SPIRIT Women avalia o stent eluidor de everolimus XIENCE TM V em lesões de novo complexas em uma população feminina do mundo real, incluindo pacientes latino-americanas. Esta análise permite compreender como essa população responde ao implante de stent, comparativamente a pacientes não-latino-americanas. MÉTODOS: Das 1.572 pacientes matriculadas em 73 locais fora dos Estados Unidos, 138 (9%) foram recrutadas na Argentina, no Brasil e na Venezuela. RESULTADOS: As lesões-alvo tinham diâmetro de referência do vaso entre 2,25 mm e 4 mm e extensão da lesão ≤ 28 mm. As características basais foram semelhantes entre os grupos, com exceção de maior prevalência de hipertensão arterial, infarto do miocárdio (IM) de parede anterior e história familiar de doença arterial coronária na coorte latino-americana. As lesões tendiam a ser mais complexas em mulheres latino-americanas, com menor diâmetro de referência do vaso-alvo, maior extensão da lesão, maior excentricidade e angulação e mais lesões tipo B2/C. Os eventos foram adjudicados de acordo com as definições do Academic Research Consortium. Em um ano, o desfecho combinado de morte por todas as causas, IM e revascularização do vaso-alvo (RVA) foi de 12,1% na população não-latino-americana e de 10,1% na população latino-americana (P = 0,58). CONCLUSÕES: Em um ano, os baixos índices de eventos cardíacos adversos, incluindo trombose do stent, falha da lesão-alvo, morte cardíaca, IM e RVA nas mulheres latino-americanas foram comparáveis aos das mulheres não-latino-americanas, apesar da maior complexidade das lesões. Esses resultados demonstram a segurança e a eficácia do stent XIENCE TM V nessa pequena coorte de pacientes latino-americanas, à semelhança do que é observado com populações maiores e mais variadas.

BACKGROUND: Drug-eluting stent trials have predominantly examined male populations of European descent. SPIRIT Women single-arm study evaluates the XIENCE TM V everolimus-eluting stent in complex de novo lesions in a real world female population, including Latin American patients. This analysis provides an insight into how this population responds to stenting when compared to non-Latin American patients. METHODS: Of the 1,572 patients enrolled from 73 non-US sites, 138 (9%) were recruited from Argentina, Brazil and Venezuela. RESULTS: Target lesions had reference vessel diameter ranging between 2.25 mm and 4 mm and lesion length ≤ 28 mm. Baseline characteristics were similar between the groups, with exception to a higher prevalence of hypertension, anterior myocardial infarction (MI) and family history of coronary artery disease in the Latin American cohort. Lesions tended to be more complex in Latin American women with a smaller reference vessel diameter, longer lesion length, increased eccentricity and angulation, and more type B2/C lesions. Events were adjudicated according to the guidelines of the Academic Research Consortium. At 1 year, the composite endpoint of death, MI and target vessel revascularization (TVR) was 12.1% in the non-Latin American population and 10.1% in the Latin American population (P = 0.58). CONCLUSIONS: At 1 year, the low rates of adverse cardiac events, including stent thrombosis, target lesion failure, cardiac death, MI and TVR in Latin American women were comparable to those of the non-Latin American women, despite the higher complexity of lesions. These results demonstrate the safety and efficacy of the XIENCE TM V stent in this small cohort of Latin American patients, in line with what is observed in larger and more varied populations.

The SPIRIT V study: a clinical evaluation of the XIENCE V everolimus-eluting coronary stent system in the treatment of patients with de novo coronary artery lesions.

OBJECTIVES: The SPIRIT V (A Clinical Evaluation of the XIENCE V Everolimus-Eluting Coronary Stent System in the Treatment of Patients With De Novo Coronary Artery Lesions) study is a post-market surveillance experience of the XIENCE V (Abbott Vascular, Santa Clara, California) everolimus-eluting stent (EES) in patients with higher-risk coronary anatomy. BACKGROUND: Previous pre-approval studies have shown the safety and efficacy of EES in highly selected groups of patients. METHODS: The SPIRIT V trial is a prospective, open label, single arm, multicenter study. Two thousand seven hundred patients with multiple de novo coronary artery lesions suitable for treatment with a planned maximum of 4 EES were enrolled at 93 centers in Europe, Asia Pacific, Canada, and South Africa. Lesions had a reference vessel diameter between 2.25 and 4.0 mm and a length of ≤ 28 mm by visual estimation. An independent clinical events committee adjudicated all end point-related events. The primary end point was the composite rate of all death, myocardial infarction (MI), and target vessel revascularization at 30 days. Secondary end points included stent thrombosis and acute success (clinical device and procedure success). RESULTS: At 30 days, the primary composite end point of all death, MI, and target vessel revascularization was 2.7%. At 1 year, rates of cardiac death, overall MI, and target lesion revascularization were 1.1%, 3.5%, and 1.8%, respectively. The cumulative rate of definite and probable stent thrombosis was low at 0.66% at 1 year. CONCLUSIONS: Use of EES in patients with multiple, complex de novo lesions yielded 1-year major adverse cardiac events, stent thrombosis, and target lesion revascularization rates that are comparable to those of the more controlled SPIRIT II and SPIRIT III trials-which included patients with restricted inclusion/exclusion criteria-and other all-comer population, physician-initiated studies like the X-SEARCH (Xience Stent Evaluated At Rotterdam Cardiology Hospital) and COMPARE (A Randomized Controlled Trial of Everolimus-eluting Stents and Paclitaxel-eluting Stents for Coronary Revascularization in Daily Practice) trials.

Evaluation of the XIENCE V everolimus eluting coronary stent system in the Asian population of the SPIRIT V single arm study. 2-year clinical follow-up data.

BACKGROUND: Asian patients have a uniquely high risk for heart disease compared to other ethnicities. Past drug eluting stent trials have examined mainly populations of European heritage. As a significant proportion of the real world population in the SPIRIT V single arm study is Asian, the study provides insight into how this population responds to stenting with the XIENCE V Everolimus Eluting Coronary Stent (EES). METHODS AND RESULTS: 2,700 patients were enrolled at 93 sites in Europe, Asia Pacific and Canada between November 2006 and November 2007. 698 (26%) patients were recruited from Asian sites in India, China, Hong Kong, Malaysia, Singapore and Thailand. De novo coronary artery lesions of all patients were to be treated with up to 4 planned EES. Up to 2 year follow-up, major adverse cardiac events, myocardial infarction and target lesion revascularization rates were lower in the Asian subgroup than in the non-Asian subgroup. These results were mainly driven by better clinical outcomes in the Indian population. All populations showed similar low stent thrombosis rates. CONCLUSION: These findings demonstrate the safety and efficacy of the EES when used in a real-world Asian population, known to be at higher risk for heart disease.
