This mechanistic study is designed to investigate the effect of vildagliptin on the sensitivity of the a-cell to glucose under hypoglycemic conditions in patients with type 2 diabetes (T2DM).

Condition Intervention Phase
Diabetes Mellitus, Type 2
Drug: Vildagliptin
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Pharmacodynamics Study
Intervention Model: Crossover Assignment
Masking: Double-Blind
Primary Purpose: Treatment
Official Title: A Single-center, Double-blind, Randomized, Placebo-controlled, Cross-over Study to Assess the Effect of Vildagliptin on Glucagon Counterregulatory Response During Hypoglycemia in Patients With Type 2 Diabetes.

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Glucagon counterregulatory response to hypoglycemia of the last 30 min of the 2.5 mM hypoglycemic clamp after 4 weeks treatment

Secondary Outcome Measures:
  • Glucagon counterregulatory response to hypoglycemia assessed as glucagon Cmax of the 2.5 mM hypoglycemic clamp step after 4 weeks treatment
  • The 'insulin secretion rate relative to glucose' at the hypoglycemic clamp step after 4 weeks treatment
  • Change from baseline on hemoglobinA1c (HbA1c)and fasting plasma glucose
  • Safety based primarily on frequency of adverse events, number of notable abnormal laboratory values, and frequency and severity of hypoglycemic events

Estimated Enrollment: 28
Study Start Date: September 2006
