Brief Summary:
The purpose of this study is to assess the safety, tolerability, effect of vildagliptin and how the body changes the blood level of vildagliptin of single and multiple oral doses of vildagliptin in healthy Chinese volunteers.

Condition or disease Intervention/treatment Phase
Healthy Drug: Vildagliptin (LAF237) Phase 1

Study Type : Interventional  (Clinical Trial)
Enrollment : 60 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Randomized, Double-Blind, Placebo-Controlled, Time-Lagged, Parallel-Group, Ascending Single and Multiple Oral Dose Study of the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of LAF237 in Chinese Healthy Subjects
Study Start Date : September 2006

Primary Outcome Measures :
  1. Safety and tolerability of single dose of vildagliptin in healthy Chinese volunteers at four sequentially ascending dose levels
  2. Safety and tolerability of repeated doses of vildagliptin in healthy Chinese volunteers at five sequentially ascending dose levels
  3. Pharmacokinetics and pharmacodynamics of vildagliptin in healthy Chinese volunteers at five sequentially ascending dose levels

Secondary Outcome Measures :
  1. Pharmacokinetic/pharmacodynamic relationship in healthy Chinese volunteers
