Further study details as provided by Bristol-Myers Squibb:

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 ]

Estimated Enrollment: 12000
Study Start Date: May 2010
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: May 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts
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.

Detailed Description:

Involving a secondary analysis of data collected prospectively from a defined cohort, for the SAVOR trial.

  Eligibility

Ages Eligible for Study:   40 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

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.

Exclusion Criteria:

  • Not enrolled in SAVOR
