This 3-arm study will assess the efficacy, safety and tolerability of taspoglutide compared to insulin glargine in patients with insulin-naive type 2 diabetes mellitus inadequately controlled with metformin and sulphonylurea combination therapy. Patients will be randomized to receive taspoglutide (10 mg once weekly, or 10mg once weekly for 4 weeks followed by 20mg once weekly) or insulin glargine (starting dose 10 IU/day) in a ratio of 1:1:1 in addition to continued prestudy metformin treatment. The anticipated time on study treatment is 2+ years, and the target sample size if 500+ individuals.

Primary Outcome Measures:
  • Absolute change from baseline in HbA1c [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Change from baseline in fasting plasma glucose; change from baseline in body weight; responder rates for HbA1c (target <=7.0%, <=6.5%); incidence of hypoglycemia; change from baseline in lipid profile. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Relative change in glucose, insulin, C-peptide and glucagon during a meal tolerance test. [ Time Frame: 24 weeks ] [ Designated as safety issue: No ]
  • Safety: Adverse events, vital signs, physical examination, clinical laboratory tests, ECG and anti-taspoglutide antibodies [ Time Frame: Throughout study ] [ Designated as safety issue: No ]
