E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objectives: Efficacy The primary efficacy objective is to determine, as a superiority assessment, whether treatment with saxagliptin compared with placebo when added to current background therapy will result in a reduction in the composite endpoint of cardiovascular death, non-fatal myocardial infarction or non-fatal ischaemic stroke, in patients with type 2 diabetes mellitus. Safety The primary safety objective of this trial is to establish that the upper bound of the 2-sided 95% confidence interval for the estimated risk ratio comparing the incidence of the composite endpoint of cardiovascular death, non fatal myocardial infarction or non-fatal ischaemic stroke, in patients with type 2 diabetes mellitus, observed with saxagliptin to that observed in the placebo group is less than 1.3. |
|
E.2.2 | Secondary objectives of the trial |
Secondary efficacy objective: The secondary efficacy objective is to determine whether treatment with saxagliptin compared with placebo when added to current background therapy in patients with type 2 diabetes mellitus will result in a reduction of the composite endpoint of cardiovascular death, non fatal myocardial infarction, non-fatal ischaemic stroke, hospitalisation for heart failure, hospitalisation for unstable angina pectoris or hospitalisation for coronary revascularisation. Secondary safety objectives: Safety and tolerability will be evaluated by assessment of overall adverse events and adverse events of special interest. These will include assessment of the long-term effects of saxagliptin on decrease in lymphocyte counts, decrease in thrombocyte counts, severe infections, hypersensitivity reactions, liver abnormalities, bone fractures, pancreatitis, skin reactions and renal abnormalities. |

E.3 | Principal inclusion criteria |
4.1 Inclusion criteria For inclusion in the study, patients should fulfil the following criteria: 1. Provision of informed consent prior to any study-specific procedures 2. Age ≥40 years 3. Diagnosed with T2DM based on the current American Diabetes Association guidelines 4. HbA1c ≥6.5% (based on the last measured and documented laboratory measurement in the previous 6 months) 5. High risk for a CV event defined as having either established CV disease and/or multiple risk factors: Established CV disease (see Appendix E): � Ischaemic heart disease, and/or � Peripheral vascular disease (eg, intermittent claudication), and/or � Ischaemic stroke Multiple Risk Factors Patient must be at least 55 years old (men) and 60 years old (females) and have at least one additional risk factor (treated or non-treated) from the following: � Dyslipidemia (based on the last measured and documented laboratory measurement in the previous 6 months and defined as at least 1 of the following): o High level of low-density lipoprotein cholesterol (LDL-C), defined as >130 mg/dL (> 3.36 mmol/L) o Low level of high-density lipoprotein cholesterol (HDL-C), defined as <40 mg/dL (<1.04 mmol/L) for men or <50 mg/dL (<1.30 mmol/L) for women � Hypertension, as confirmed at the enrolment visit o BP >140/90 mm/Hg or on a BP-lowering agent with BP >130/80 mm/Hg �Currently smoking, as confirmed at the enrolment visit 6.Women of childbearing potential (WOCBP) must take precautions to avoid pregnancy throughout the study and for 4 weeks after intake of the last dose. Men participating in the study should also take precautions not to father a child while participating in the study and for 4 weeks after intake of the last dose. WOCBP must have a negative urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin) within 72 hours prior to the start of study medication. WOCBP include any female who has experienced menarche and who has not undergone successful surgical sterilisation (hysterectomy, bilateral tubal ligation or bilateral oophorectomy) or is not postmenopausal (defined as amenorrhea ≥2 consecutive years). Inclusion criteria for the optional biological research The inclusion criteria for the optional biological research are provided in Appendix H. If a patient declines to participate in the biological research, there will be no penalty or loss of benefit to the patient. The patient will not be excluded from other aspects of the study as described in this protocol, as long as consent to the main study has been obtained. Inclusion criteria for the optional genetic research The inclusion criteria for the optional genetic research are provided in Appendix F. If a patient declines to participate in the genetic research, there will be no penalty or loss of benefit to the patient. The patient will not be excluded from other aspects of the study as described in this protocol, as long as consent to the main study has been obtained. It is possible that a patient may be randomised into the main study before the genetic component has been approved by the institution s Institutional Review Board (IRB). If that patient elects to participate in the genetic portion of this study, after IRB approval is granted, he/she may do so. The genetic sample is not limited to collection at Visit 1 but may be collected at any visit, provided that written informed consent for collecting the sample has been obtained. |

E.4 | Principal exclusion criteria |
4.2 Exclusion criteria Patients should not enter the study if any of the following exclusion criteria are fulfilled: 1. Any conditions that, in the opinion of the Investigator, may render the patient unable to complete the study including non-CV disease (eg, active malignancy, cardiomyopathy, cirrhosis, or chronic lung disease) with a likely fatal outcome within 5 years 2. Current or previous (within 6 months) treatment with an incretin-based therapy such as DPP4 inhibitors and or GLP 1 mimetics 3. Acute vascular (cardiac or stroke) event <2 months prior to randomisation 4. Initiation of chronic dialysis and/or renal transplant and/or a serum creatinine >6.0 mg/dL 5. Pregnant or breast-feeding patients 6. History of human immunodeficiency virus 7. Patients being treated for severe auto immune diseases such as lupus 8. Any patient currently receiving chronic (>30 consecutive days) treatment with an oral steroid 9. Patients with: � Body mass index >50 kg/m2 � Last measured HbA1c ≥12% � Sustained BP >180/100 mm Hg � LDL-C >250 mg/dL (> 6.48 mmol/L) (based on the last measured and documented laboratory measurement in the previous 6 months) � Triglycerides >1000 mg/dL (>11.3 mmol/L) (based on the last measured and documented laboratory measurement in the previous 6 months) � HDL-C <25 mg/dL (<0.64 mmol/L) (based on the last measured and documented laboratory measurement in the previous 6 months) � Known liver function tests >3 times upper limit of normal (ULN), (based on the last measured and documented laboratory measurement in the previous 6 months) 10. Involvement in the planning and/or conduct of the study (applies to both AstraZeneca and BMS or representative staff and/or staff at the study site) 11. Previous randomisation in the present study 12. Participation in another clinical study with IP and/or intervention within 30 days prior to Visit 1 13. Individuals at risk for poor protocol or medication compliance For procedures for withdrawal of incorrectly randomised patients, see Section 5.3. Exclusion criteria for the optional genetic research The exclusion criteria for the optional genetic research are provided in Appendix F. |
