  Purpose

This study is designed to evaluate safety and efficacy of vildagliptin versus NPH insulin add-on to glimepiride in patients with type 2 diabetes mellitus that do not reach adequate glycemic control on their current sulfonylurea monotherapy to give treating physicians a guidance which additional anti-diabetic treatment can be used if sulfonylurea monotherapy is not sufficient to reach glycemic control.

Primary Outcome Measures:
  • Percentage of patients reaching HbA1c below 7.0% without confirmed hypoglycemia and weight gain [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    Primary endpoint is proportion of patients reaching the combined endpoint, defined as a blood glucose target (HbA1c below 7.0%) without any confirmed hypoglycemic events (BG measurement < 3.9mM (71mg/dL)) and weight gain.

  • Rate of confirmed hypoglycemic events [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
    Co-primary endpoint is to evaluate the rate of confirmed hypoglycemic events (BG measurement < 3.9mM (71mg/dL)) in type 2 diabetes patients treated with vildagliptinversus NPH insulin add-on to glimepiride.


Secondary Outcome Measures:
  • Incidence of severe hypoglycemic events [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
    To evaluatethe incidence of severe hypoglycemic events (suspected grade 2 and confirmed grade 2 events) in patients treated with vildagliptin versus NPH insulin add-on to glimepiride.

  • Incidence of symptomatic hypoglycemic events [ Time Frame: 24 weeks ] [ Designated as safety issue: Yes ]
    To evaluate the incidence of symptomatic hypoglycemic events in patients treated with vildagliptin versus NPH insulin add-on to glimepiride.

  • Percentage of patients who reach their blood glucose target (HbA1c below 7.0%) without any confirmed hypoglycemic event [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
    To evaluate thepercentage of patients treated with vildagliptin versus NPH insulin add-on to glimepiride who reach their blood glucose target (HbA1c below 7.0%) without any confirmed hypoglycemic events.

  • Change from baseline in body weight at 24 weeks [ Time Frame: Baseline, 24 week ] [ Designated as safety issue: No ]
    To evaluate body weight changes between study begin and study end in patients treated with vildagliptin versus NPH insulin add-on to glimepiride.

  • Change from baseline in HbA1c at 24 weeks [ Time Frame: Baseline, 24 week ] [ Designated as safety issue: No ]
    To evaluate changes in HbA1c between study begin and study end in patients treated with vildagliptin versus NPH insulin add-on to glimepiride.

  • Change from baseline in Treatment Satisfaction Questionnaire for Medication (TSQM-9) at 24 week [ Time Frame: Baseline, 24 week ] [ Designated as safety issue: No ]
    The TSQM-9 is a psychometrically sound and valid measure of the major dimensions of patients' satisfaction with medication.

Study Start Date: August 2012
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vildagliptin
Patients randomized to the vildagliptin group will receive 50mg vildagliptin once daily add-on to their current glimepiride monotherapy for 24 weeks. No dose titrations are permitted during the study.
Drug: LAF237
Vildagliptin will be used as commercially available tablets of 50mg.
Active Comparator: Protaphane
Patients randomized to the Protaphane group will receive a individulazed dose of Protaphane once daily as bedtime dose. The Protaphane dose will be titrated within the first 4 weeks to reach fasting plasma glucose values below 100 mg/dl.
Drug: Protaphane
Protaphane will be used as commercially available injection pens
