This study has been completed.
Sponsor:
Collaborator:
Eli Lilly and Company
Information provided by (Responsible Party):
Boehringer Ingelheim
ClinicalTrials.gov Identifier:
NCT00954447
First received: August 6, 2009
Last updated: December 4, 2013
Last verified: October 2012
  Purpose
The objective of the current study is to investigate the efficacy, safety and tolerability of linagliptin (5 mg / once daily) compared to Placebo during long term treatment (52 weeks and longer) in combination with basal insulin in patients with type 2 diabetes mellitus with insufficient glycaemic control.

Condition Intervention Phase

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Phase III Randomised, Double-blind, Placebo-controlled, Parallel Group Efficacy and Safety Study of Linagliptin (5 mg), Administered Orally Once Daily for at Least 52 Weeks in Type 2 Diabetic Patients in Combination With Basal Insulin Therapy

Primary Outcome Measures:
  • Change From Baseline in HbA1c After 24 Weeks [ Time Frame: Baseline and 24 weeks ]
    HbA1c is measured as a percentage. Adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant Oral antidiabetic drugs (OAD)


Secondary Outcome Measures:
  • Number of Patients With HbA1c < 7.0 Percent [ Time Frame: 24 and 52 weeks ]
  • Number of Patients Lowering HbA1c by at Least 0.5 Percent [ Time Frame: 24 and 52 weeks ]
  • Change From Baseline in HbA1c by Visit at Week 6 [ Time Frame: Baseline and 6 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in HbA1c by Visit at Week 12 [ Time Frame: Baseline and 12 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in HbA1c by Visit at Week 18 [ Time Frame: Baseline and 18 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in HbA1c by Visit at Week 32 [ Time Frame: Baseline and 32 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in HbA1c by Visit at Week 40 [ Time Frame: Baseline and 40 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in HbA1c by Visit at Week 52 [ Time Frame: Baseline and 52 weeks ]
    Means adjusted for treatment, baseline HbA1c, categorical renal function impairment and concomitant OADs

  • Change From Baseline in Fasting Plasma Glucose (FPG) at 24 Weeks of Treatment [ Time Frame: Baseline and 24 weeks ]
    Means adjusted for treatment, baseline HbA1c, baseline FPG, categorical renal function impairment and concomitant OADs

  • Change From Baseline in Fasting Plasma Glucose (FPG) After 52 Weeks of Treatment [ Time Frame: Baseline and 52 weeks ]
  • Change From Baseline in FPG [ Time Frame: Baseline, 6, 12, 18, 24, 32 and 40 weeks ]
  • Change From Baseline in Mean Insulin Dose at 52 Weeks of Treatment [ Time Frame: Baseline and 52 weeks ]
    Means adjusted for treatment, continous baseline HbA1c, continous baseline weight, continous baseline Insulin, categorical renal function impairment and concomitant OADs

  • Change From Baseline in Weighted Mean Daily Glucose After 24 and 52 Weeks of Treatment [ Time Frame: Baseline, 24 and 52 weeks ]
    Mean Daily Glucose was calculated using the 8-point blood glucose profile

  • Change From Baseline in Incremental Post-prandial Glucose (iPPG) After 24 Weeks of Treatment [ Time Frame: Baseline and 24 weeks: post-breakfast, post-lunch, post-dinner ]

Other Outcome Measures:
  • Number of Patients With HbA1c < 6.5 Percent [ Time Frame: 24 and 52 weeks ]
