The objective of this trial is to investigate the pharmacokinetics and pharmacodynamics of linagliptin (BI 1356) 5 mg administered orally in patients with Type 2 diabetes mellitus of African American origin.

Condition Intervention Phase
Diabetes Mellitus, Type 2
Drug: linagliptin QD (once daily) for 7 days
Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: An Open Label, Phase I Trial to Investigate the Pharmacokinetics and Pharmacodynamics of Linagliptin (BI 1356) 5 mg After Single and Multiple Oral Administration in Patients With Type 2 Diabetes Mellitus of African American Origin for 7 Days

Primary Outcome Measures:
  • Linagliptin: AUC_τ,ss [ Time Frame: 24 hours ]
    area under the concentration time curve (AUC_τ) of linagliptin in plasma at steady state over a uniform dosing interval

  • Linagliptin: C_max,ss [ Time Frame: 24 hours ]
    maximum concentration of linagliptin in plasma at steady state

  • DPP-4 Inhibition: E_24,ss [ Time Frame: One single measurement 24 h after drug administration under steady state conditions ]
    Plasma DPP-4 inhibition at trough under steady state conditions. Plasma DPP-4 inhibition is derived by calculating (1-(activity in presence of linagliptin)/baseline activity))*100%, where 'activity' is the activity of the DPP-IV enzyme.

Secondary Outcome Measures:
  • Treatment Emergent Adverse Events [ Time Frame: 21 days ]
    Frequency of patients with AEs

  • Electrocardiogram (ECG), Vital Signs, Physical Finding or Laboratory Finding Abnormalities [ Time Frame: 21 days ]
    12-lead-Electrocardiogram (ECG), vital sign (blood pressure and pulse rate), physical finding and laboratory abnormalities

  • Patients With Electrocardiogram (ECG), Vital Signs, Physical Finding or Laboratory Finding Abnormalities Reported as an Adverse Event [ Time Frame: 21 days ]
    Patients with Electrocardiogram (ECG), vital signs, physical finding reported as an adverse event

  • Linagliptin: AUC_0-24 [ Time Frame: 24 hours ]
    area under the concentration time curve of linagliptin in plasma over the time interval from 0 to 24h after administration of the first dose

  • Linagliptin: C_max [ Time Frame: 24h ]
    maximum concentration of linagliptin in plasma on Day 1

  • DPP-4 Inhibition: E_24 [ Time Frame: One single measurement 24 h after drug administration ]
    Plasma DPP-4 inhibition 24 hours after first dose. Plasma DPP-4 inhibition is derived by calculating (1-(activity in presence of linagliptin)/baseline activity))*100%, where 'activity' is the activity of the DPP-IV enzyme.

Enrollment: 41
Study Start Date: June 2009
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: linagliptin
Pharmacokinetic (PK)/Pharmacodynamic (PD) investigation
Drug: linagliptin QD (once daily) for 7 days
dipeptidyl peptidase IV (DPP-4) activity will be measured as PD response to drug administration
