This 3 arm study will assess the efficacy, safety and tolerability of taspoglutide compared to placebo in patients with type 2 diabetes mellitus inadequately controlled with diet and exercise. Patients will be randomized to one of 3 treatment arms: taspoglutide 10mg sc once weekly, taspoglutide 20mg sc once weekly (after 4 weeks of taspoglutide 10mg sc once weekly) or placebo. After the first 24 weeks patients on placebo will be switched to taspoglutide 10mg once weekly or taspoglutide 20mg once weekly (after 4 weeks of taspoglutide 10mg once weekly). The anticipated time on study treatment is 1 year, and the target sample size is 100-500 individuals.

Primary Outcome Measures:
  • Absolute change from baseline in HbA1c [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • Safety: Adverse events, vital signs, physical examination, clinical laboratory tests, ECG and anti-taspoglutide antibodies. [ Time Frame: Throughout study ]
  • Change from baseline in fasting plasma glucose; change from baseline in body weight. [ Time Frame: 24 weeks ]
  • Responder rates for HbA1c (target <=7.0%, <=6.5%); relative change in glucose, insulin, C-peptide and glucagon during a meal tolerance test; beta cell function. [ Time Frame: 24 weeks ]
