The purpose of this study is to identify risk factors for low lymphocyte count among patients with type 2 diabetes who are treated with oral antidiabetic drugs.
Diabetes Mellitus, Type 2
||Time Perspective: Prospective
||Identification of Risk Factors for Low Lymphocyte Count in Patients With Type 2 Diabetes: An Analysis of Data From the SAVOR Study
Primary Outcome Measures:
- To identify risk factors for lymphopenia, defined as an absolute lymphocyte count < 500 cells/μl, or investigator reported lymphopenia, in the SAVOR study population. [ Time Frame: 60 months ] [ Designated as safety issue: Yes ]
Secondary Outcome Measures:
- To identify risk factors for absolute lymphocyte count <750 cells/µl or investigator reported lymphopenia. [ Time Frame: 60 months ] [ Designated as safety issue: Yes ]
- To identify risk factors for decreased lymphocyte count (>=30% decrease from baseline. [ Time Frame: 60 months ] [ Designated as safety issue: Yes ]
- To evaluate whether risk factors for low lymphocyte counts or decreasing lymphocyte count differ between saxagliptin users and non-users. [ Time Frame: 60 months ] [ Designated as safety issue: Yes ]

Patients treated with saxagliptin or placebo
Patients will be treated with saxagliptin or placebo, on top of whatever baseline treatment for diabetes the patient is already receiving.
Patients currently or previously on treatment
Patients currently or previously on (within 6 months) treatment with DPP4 inhibitors and/or GLP-1 mimetics are excluded.
Involving a secondary analysis of data collected prospectively from a defined cohort, for the SAVOR trial.
|Ages Eligible for Study:
||40 Years and older
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
Patients enrolled in the Saxagliptin Assessment of Vascular Outcomes Recorded in Diabetes Mellitus study, which is a randomized, placebo-controlled phase 4 study of cardiovascular outcomes). 12,000 patients with type 2 diabetes and either a history of a cardiovascular event or multiple risk factors for vascular disease. Patients will be distributed as follows: at least 30% in North America, approximately 30% in Europe, and the remainder in South America, Asia, Australia, and South Africa.
- Enrolled in SAVOR
- Diagnosed with T2DM
- Baseline HbA1c ≥6.5% (based on the last measured and documented laboratory measurement within 6 months)
- Age 40 or older
- High risk for a cardiovascular event
- Not enrolled in SAVOR
- Current or previous treatment with DPP4 inhibitors and/or GLP-1 or incretin mimetics.
- Acute vascular event
- Severe autoimmune disease
- Current chronic steroid use
