Examination of the effect of Linagliptin versus placebo on diastolic function in patients with type 2 diabetes mellitus and diastolic dysfunction as assessed by transthoracic echocardiography.

Furthermore the effect on serum levels of NT-pro BNP as a biomarker of heart failure will be investigated.

Further study details as provided by RWTH Aachen University:

Primary Outcome Measures:
  • Change in left ventricular diastolic function [ Time Frame: baseline and 6 months ]
    Change in left ventricular diastolic function between baseline and after 6 month as determined by 2D and novel 3D parameter global Strain Rate E Change in left ventricular diastolic function between baseline and after 6 month as determined by standardized parameter E/é and left atrial (LA) volume

Secondary Outcome Measures:
  • Change in serum NT-pro BNP levels [ Time Frame: baseline and 6 months ]
    Change in serum NT-pro BNP levels

Enrollment: 8
Study Start Date: September 2013
Study Completion Date: December 2014
Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Linagliptin
Linagliptin 5 mg (tablets) once daily for 6 month
Drug: Linagliptin
Other Name: Trade name Trajenta® by Boehringer Ingelheim (BI) Pharma GmbH & Co KG, Biberach, Germany
Placebo Comparator: Placebo
Placebo (tablets) once daily for 6 month
Drug: placebo

Detailed Description:


The Patients will receive Linagliptin 5 mg QD or placebo for a period of 6 months.

The echocardiography and 24h RR measurement will be performed at baseline and 6 months after initiation of the therapy.

The blood chemistry (Glucose, HbA1c, BNP) will be evaluated at baseline as well as 3 and 6 months after initiation of the therapy.
