Plain English Summary

Background and study aims
Gliclazide is a well-known drug prescribed to control glucose levels in patients with type 2 diabetes mellitus. Diamicron MR 60 mg is a new modified-release formulation of gliclazide that enables the number of tablets per intake to be halved and allows gradual increase of dosage up to an optimal level. This new formulation is also expected to enhance compliance, meaning that more patients take their treatment properly and have better control of their diabetes.
The aim of the ongoing EasyDia program is to analyse how the new formulation Diamicron MR 60 mg is prescribed in daily clinical practice, notably of how rapidly and easily patients reach the optimal dosage.

Who can participate?
EasyDia is including over 5000 male or female patients aged 35 years or older with type 2 diabetes with glucose levels that are poorly controlled with diet or lifestyle measures or with other antidiabetic treatments (except insulin).

What does the study involve?
This is an observational study, which means that included patients are managed in exactly the same way as they would be if they were not participating in the program.

What are the possible benefits and risks of participating?
There should be no net benefit or risk for the participants as this is an observational study in which the participants will be treated as in normal practice. It should be noted that gliclazide has been in clinical use in other formulations since 40 years, and is not associated with any untoward safety issues.

Where is the study run from?
The study in taking place in 8 countries (Armenia, Russia, Switzerland, Malaysia, Georgia, The Lebanon, Slovenia, and Bangladesh) and all investigators are physicians in general practice or hospitals.

When is the study starting and how long is it expected to run for?
The first patient visit was in July 2011 and the study is expected to end in October 2013.

Who is funding the study?
The study is being funded by the French pharmaceutical company Servier.

Study information

Scientific title

ObsErvationAl Study to analYse titration of Diamicron MR 60 mg in daily clinical practice in a large population with uncontrolled type 2 diabetes



Study hypothesis

A new formulation of modified-release gliclazide 60 mg (Diamicron MR 60 mg) has been developed with the aim of allowing gradual uptitration to optimal dosage as well as halving the number of tablets per administration at maintenance dosage. This 6-month, multicenter, open-label, non-randomized, non-comparative, observational study was designed to assess the prescription of gliclazide MR 60 mg in primary care, notably during the titration phase of treatment.

Type 2 diabetes mellitus


This observational study is performed in patients receiving gliclazide MR 60 mg as the basis of their treatment strategy:
1. Newly diagnosed patients will be initiated on gliclazide MR 60 mg.
2. Previously diagnosed patients will be switched to gliclazide MR 60 mg or receive it added on to their current treatment.

The starting dose of gliclazide MR 60 mg will be defined according to the judgment of the investigators and the Summary of Product Characteristics.

Dose increases will be made at each study visit (1, 2, and 3 months) according to fasting plasma glucose and patient characteristics (especially regarding elderly patients or those with renal insufficiency), up to a maximal dose of 120 mg (2 tablets) per day in a single intake at breakfast, before adding any other oral antidiabetic drug.

Drug names

Diamicron MR 60 mg (gliclazide 60 mg)

Primary outcome measure

Time to reach the efficient dose that provides optimal glycemic control, according to the investigator's judgment

Secondary outcome measures

1. Average daily dose of gliclazide MR 60 mg at the end of the study
2. Compliance assessed by a qualitative questionnaire (addressed to the investigators)
3. Treatment doses: repartition of each dose level in the population over time
4. Efficacy parameters (HbA1c and fasting plasma glucose): change versus baseline; percentage of patients achieving an HbA1c level 6.5% or lower, and 7% or lower
5. Safety parameters
6. Treatment acceptability with assessment of body weight change
