Study type Participant information sheet
Scientific titleLong term double blind comparison of gliclazide MR (30 to 120 mg daily per os) and rosiglitazone (4 to 8 mg daily per os) given in combination with metformin in type 2 diabetic patients.A 2-year international, multicentre, randomised, double-blind, parallel-group study followed by a 2-year double blind extension. - ENDORSE
Study acronymENDORSE
Study objectivesTo compare the efficacy of the two bi-therapies administered at optimal dosage on mean weighted HbA1c over two years.
Ethics approval(s)Positive opinion from local ethics committee (Comités de Consultation pour la Protection des Personnes se prêtant à la Recherche Biomédicale [CCPPRB] Hôpital Robert Ballanger, Aulnay sous Bois, France) on 28/07/2006, ref: MCF-22/2006
Health condition(s) or problem(s) studiedType 2 diabetes
InterventionPlease note that as of 02/12/10 the status of this trial has been changed to "Stopped".
Following the publication on rosiglitazone cardiovascular safety by Nissen in May 2007 and the European Medicines Agency (EMEA) review in October 2007 on the benefits and risks of rosiglitazone and pioglitazone, the recruitment of the ENDORSE study (gliclazide MR versus rosiglitazone, on top of metformin) became no longer feasible and the study was prematurely stopped (last visit patient on 12 March 2008).

Gliclazide Modified Release (MR) versus an oral anti-diabetic on top of metformin.
Intervention typeDrug
PhasePhase III
Drug / device / biological / vaccine name(s)Gliclazide Modified Release (MR), metformin

1. Change of other metabolic parameters (Fasting Plasma Glucose, Insulin, Lipids)
2. Assessment of the safety and acceptability profile

Completion date12/03/2008
