Randomised comparison of titanium-nitride-oxide coated stents with bare metal stents: five year follow-up of the TiNOX trial

Revascularisation with Titanium-Nitride-Oxide (TiNOX) coated stents is safe and effective in patients with de novo native coronary artery lesions. In the TiNOX trial there was a reduction in restenosis and major adverse cardiac events as compared with stainless steel stents of otherwise identical design. The purpose of the present study was to evaluate the long-term outcome of these patients over five years.

Effect of fibroblast growth factor NV1FGF on amputation and death: a randomised placebo-controlled trial of gene therapy in critical limb ischaemia

Patients with critical limb ischaemia have a high rate of amputation and mortality. We tested the hypothesis that non-viral 1 fibroblast growth factor (NV1FGF) would improve amputation-free survival.

Terutroban versus aspirin in patients with cerebral ischaemic events (PERFORM): a randomised, double-blind, parallel-group trial

Patients with ischaemic stroke or transient ischaemic attack (TIA) are at high risk of recurrent stroke or other cardiovascular events. We compared the selective thromboxane-prostaglandin receptor antagonist terutroban with aspirin in the prevention of cerebral and cardiovascular ischaemic events in patients with a recent non-cardioembolic cerebral ischaemic event.

Anti-infective treatment of peri-implant mucositis: a randomised controlled clinical trial

Assessment of letrozole and tamoxifen alone and in sequence for postmenopausal women with steroid hormone receptor-positive breast cancer: the BIG 1-98 randomised clinical trial at 8·1 years median follow-up

Postmenopausal women with hormone receptor-positive early breast cancer have persistent, long-term risk of breast-cancer recurrence and death. Therefore, trials assessing endocrine therapies for this patient population need extended follow-up. We present an update of efficacy outcomes in the Breast International Group (BIG) 1-98 study at 8·1 years median follow-up.

Outcome, quality of life and cognitive function of patients with brain metastases from non-small cell lung cancer treated with whole brain radiotherapy combined with gefitinib or temozolomide. A randomised phase II trial of the Swiss Group for Clinical Cancer Research (SAKK 70/03)

Patients with brain metastases (BM) rarely survive longer than 6months and are commonly excluded from clinical trials. We explored two combined modality regimens with novel agents with single agent activity and radiosensitizing properties.

Outpatient versus inpatient treatment for patients with acute pulmonary embolism: an international, open-label, randomised, non-inferiority trial

Although practice guidelines recommend outpatient care for selected, haemodynamically stable patients with pulmonary embolism, most treatment is presently inpatient based. We aimed to assess non-inferiority of outpatient care compared with inpatient care.

Long-term clinical outcomes of biodegradable polymer biolimus-eluting stents versus durable polymer sirolimus-eluting stents in patients with coronary artery disease (LEADERS): 4 year follow-up of a randomised non-inferiority trial

Background The effectiveness of durable polymer drug-eluting stents comes at the expense of delayed arterial healing and subsequent late adverse events such as stent thrombosis (ST). We report the 4 year follow-up of an assessment of biodegradable polymer-based drug-eluting stents, which aim to improve safety by avoiding the persistent inflammatory stimulus of durable polymers. Methods We did a multicentre, assessor-masked, non-inferiority trial. Between Nov 27, 2006, and May 18, 2007, patients aged 18 years or older with coronary artery disease were randomly allocated with a computer-generated sequence to receive either biodegradable polymer biolimus-eluting stents (BES) or durable polymer sirolimus-eluting stents (SES; 1:1 ratio). The primary endpoint was a composite of cardiac death, myocardial infarction, or clinically-indicated target vessel revascularisation (TVR); patients were followed-up for 4 years. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00389220. Findings 1707 patients with 2472 lesions were randomly allocated to receive either biodegradable polymer BES (857 patients, 1257 lesions) or durable polymer SES (850 patients, 1215 lesions). At 4 years, biodegradable polymer BES were non-inferior to durable polymer SES for the primary endpoint: 160 (18·7%) patients versus 192 (22·6%) patients (rate ratios [RR] 0·81, 95% CI 0·66–1·00, p for non-inferiority <0·0001, p for superiority=0·050). The RR of definite ST was 0·62 (0·35–1·08, p=0·09), which was largely attributable to a lower risk of very late definite ST between years 1 and 4 in the BES group than in the SES group (RR 0·20, 95% CI 0·06–0·67, p=0·004). Conversely, the RR of definite ST during the first year was 0·99 (0·51–1·95; p=0·98) and the test for interaction between RR of definite ST and time was positive (pinteraction=0·017). We recorded an interaction with time for events associated with ST but not for other events. For primary endpoint events associated with ST, the RR was 0·86 (0·41–1·80) during the first year and 0·17 (0·04–0·78) during subsequent years (pinteraction=0·049). Interpretation Biodegradable polymer BES are non-inferior to durable polymer SES and, by reducing the risk of cardiac events associated with very late ST, might improve long-term clinical outcomes for up to 4 years compared with durable polymer SES.

The three year follow-up of the randomised "all-comers" trial of a biodegradable polymer biolimus-eluting stent versus permanent polymer sirolimus-eluting stent (LEADERS)

Aims: The current study reports clinical outcomes at three year follow-up of the LEADERS clinical trial which was the first all-comers trial comparing a new generation biodegradable polymer biolimus drug-eluting stent (BES) with the first generation permanent polymer sirolimus-eluting stent (SES). Methods and results: One thousand seven hundred and seven patients were randomised to unrestricted use of BES (n=857) or SES (n=850) in an all-comers population. Three year follow-up was available in 95% of the patients, 812 treated with BES and 809 treated with SES. At three years, BES remains non-inferior to SES for the primary endpoint of major adverse cardiac events (composite of cardiac death, myocardial infarction (MI), or clinically-indicated target vessel revascularisation (CI-TVR) (BES 15.7% versus SES 19%; HR 0.82 CI 0.65-1.03; p=0.09). The MACE Kaplan Meier event curves increasingly diverge with the difference in events increasing from 1.4% to 2.4% and 3.3% at 1, 2 and 3 years, respectively in favour of BES. The rate of cardiac death was non-significantly lower 4.2% versus 5.2% (HR=0.81 CI 0.52-1.26; p=0.34) and the rate of myocardial infarction was equivalent 7.2% versus 7.1% (HR 1.01 CI 0.70-1.44; p=0.97) for BES versus SES, respectively. Thus BES was non-inferior to SES in all the safety endpoints. Clinically-indicated TVR occurred in 9.4% of BES treated patients versus 11.1% of SES treated patients (HR 0.84 CI 0.62-1.13; p=0.25). Rates of definite stent thrombosis were 2.2% for BES and 2.9% for SES (HR 0.78 CI 0.43-1.43; p=0.43), with the event rate increase of 0.2% from one to three years for BES and 0.9% for SES. For patients presenting with ST-elevation myocardial infarction BES was superior to SES in reducing MACE. Conclusions: The findings of the three year follow-up support the claim that the biodegradable polymer biolimus-eluting stent has equivalent safety and efficacy to permanent polymer sirolimus-eluting stent in an all-comers patient population. Its performance is superior in some subpopulations such as in ST-elevation MI patients and event rates for BES are overall lower than for SES with a trend toward increasing divergence of outcomes over three years. - See more at: http://www.pcronline.com/eurointervention/42nd_issue/125/#sthash.E5HhMQ4a.dpuf

Unrestricted randomised use of two new generation drug-eluting coronary stents: 2-year patient-related versus stent-related outcomes from the RESOLUTE All Comers trial

In the RESOLUTE All Comers trial, the Resolute zotarolimus-eluting stent was non-inferior to the Xience V everolimus-eluting stent for the primary stent-related endpoint of target lesion failure (cardiac death, target vessel myocardial infarction, and ischaemia-driven target lesion revascularisation) at 1 year. However, data for long-term safety and efficacy from randomised studies of new generation drug-eluting coronary stents in patients treated in routine clinical practice are scarce. We report the prespecified 2-year clinical outcomes from the RESOLUTE All Comers trial.

Randomised clinical trial: effects of monotherapy with ADX10059, a mGluR5 inhibitor, on symptoms and reflux events in patients with gastro-oesophageal reflux disease
