Hoffmann-La Roche Identifier:
First received: August 18, 2009
Last updated: November 1, 2016
Last verified: November 2016
This randomized, double-blind, placebo-controlled study will assess the efficacy, safety, tolerability, pharmacokinetics and pharmacodynamics of RO5095932 in patients with type 2 diabetes mellitus. Patients will be randomized to receive either RO5095932 subcutaneously once weekly or placebo for 4 weeks (part 1) or 6 weeks (part 2), in addition to their current stable doses of metformin.

Primary Outcome Measures:
  • Safety and tolerability: AEs, laboratory parameters, ECG, body weight, vital signs [ Time Frame: monitored throughout study, with weekly ECG and 2x weekly to 2-weekly laboratory assessments on study treatment and at intervals during follow-up ]
  • Change in hemoglobin A1c (HbA1c) [ Time Frame: from baseline to week 6 ]

Secondary Outcome Measures:
  • Pharmacokinetics: blood concentration of RO5095932 after multiple dosing [ Time Frame: multiple sampling weeks 1-4 or 1-6 respectively, and weekly during follow-up ]
  • Change in metabolic parameters: glucose, insulin, C-peptide [ Time Frame: assessed after 4 or 6 weeks on study treatment ]
