| E.2.1 | Main objective of the trial |
To investigate the efficacy, safety and pharmacokinetics of five doses of BI 10773 compared to placebo given for 12 weeks as add-on therapy to on-going metformin therapy in patients with type 2 diabetes mellitus with insufficient glycemic control.
Investigar la eficacia, la seguridad y la farmacocinética de cinco dosis de BI 10773 comparadas con placebo y administadas durante 12 semanas añadidas a la terapia con metformina en pacientes con DM tipo 2 con un control insuficiente de la glucemia. |

Treatment with anti-obesity drugs (e.g., sibutramine, orlistat, rimonabant) within 3 months prior to informed consent; 10. Current treatment with systemic steroids at the time of informed consent or change in dosage of thyroid hormones within 6 weeks prior to informed consent; 11. Alcohol abuse within the last 3 months that would interfere with trial participation or drug abuse; 12. Treatment with an investigational drug within 2 months prior to informed consent 13.
