Acarbose Cardiovascular Evaluation Trial (ACE)

2017年7月21日 更新者:University of Oxford

A Long-term, Multicentre, Double-blind, Randomised Parallel-group Trial to Determine Whether Reducing Post-prandial Glycaemia Can Reduce Cardiovascular-related Morbidity and Mortality in Patients With Established Coronary Heart Disease or Acute Coronary Syndrome Who Have Impaired Glucose Tolerance

The purpose of this study is to determine whether acarbose therapy can reduce cardiovascular-related morbidity and mortality in patients with impaired glucose tolerance (IGT) who have established coronary heart disease (CHD) or acute coronary syndrome (ACS). A secondary objective of the study is to determine if acarbose therapy can prevent or delay transition to type 2 diabetes mellitus (T2DM) in this patient population.

武器和干预

参与者组/臂
干预/治疗
有源比较器:Acarbose
The participants were given one tablet (50mg) of acarbose per day, taken with a meal during their first week (7 days). During the second week, the dose was increased to two tablets/day (50mg twice a day i.e. 100mg/day) and then three tablets/day (50mg three times a day i.e. 150mg/day) thereafter. The maximum tolerated dose is being taken for the duration of the trial (maximum dose is 150mg/day).

研究衡量的是什么?

主要结果指标

结果测量
大体时间
A composite cardiovascular outcome defined as the time after randomisation to the first occurrence of any one of the following: -Cardiovascular death -Non-fatal MI -Non-fatal stroke -Hospitalisation for Unstable Angina -Hospitalisation for Heart Failure
大体时间:Follow-up until 728 adjudicated Primary Outcome Measures have been recorded
Follow-up until 728 adjudicated Primary Outcome Measures have been recorded

次要结果测量

结果测量
全因死亡率
Transition to type 2 diabetes confirmed by two successive diagnostic plasma glucose values (FPG >7.0 mmol/l and/or 2HPG > 11.1 mmol/l), with no intervening non-diagnostic values.
Each of the components of the primary composite cardiovascular outcome will also be analysed individually, both as first and as total events.
Major Cardiovascular Event (MACE) composite cardiovascular outcome, defined as the time after randomisation to the first occurrence of any one of the following: - Cardiovascular death - Non-fatal MI - Non-fatal stroke
Impaired renal function as evidenced by: A reduced estimate of glomerular filtration rate( eGFR <30 ml/minute/ 1.73 m2) estimated using the Chinese MDRD formula, a doubling of the baseline plasma creatinine level, a halving of the baseline eGFR
Resource use, costs and cost effectiveness
