Drug: Sulfonylurea
Drug: Antihyperglycemic Medication

Primary Outcome Measures:
  • Median Duration (in Months) of Initial Dual Therapy [ Time Frame: Up to 3 years ]
    The treatment maintenance duration corresponds to the treatment maintenance and persistence duration for dual therapy combining the same agents. Withdrawal of an agent, replacement of one agent by another or addition of a third agent is perceived as a change in treatment and, hence, the end of the treatment maintenance duration for dual therapy.

  • Percentage of Participants With Strict Changes in Initial Dual Therapy [ Time Frame: Up to 3 years ]
    Strict changes in dual therapy were defined as withdrawal of an agent, replacement of one agent by another, or the addition of a third agent. Changes in dose level were not considered strict changes.

Enrollment: 3453
Study Start Date: July 2009
Study Completion Date: August 2013
Primary Completion Date: August 2013 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Metformin + Sitagliptin
Participants taking metformin + sitagliptin (Januvia®/Xelevia®) as prescribed in routine clinical practice.
Drug: Metformin Drug: Sitagliptin
Metformin + Sulfonylurea
Participants taking metformin + sulfonylurea as prescribed in routine clinical practice. The sulfonylurea could include: gliclazide, glibenclamide, or glimepiride.
Drug: Metformin Drug: Sulfonylurea
Sitagliptin +/- Other Antihyperglycemic Medication
Participants taking sitagliptin +/- other antihyperglycemic medication (other than metformin) as prescribed in routine clinical practice. These other antihyperglycemic medications could include: insulin, glinides, sulfonylurea, glitazone, an alpha-glucosidase inhibitor, or combinations thereof.
Drug: Antihyperglycemic Medication


Ages Eligible for Study:   19 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Participants with type II diabetes mellitus receiving a de novo prescription (for the first time or within less than 8 weeks) for dual therapy with or without Januvia®/Xelevia® or any other treatment regimen including Januvia®/Xelevia® by general practitioners in private practice under real life conditions without any additional treatment or monitoring procedures.

Inclusion Criteria:

  • Type 2 diabetes participants
