E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Title: Exploratory pharmacogenetic and mRNA expression profiling sub-study for CSPP100E2337.
A randomized, double-blind, placebo-controlled, parallelgroup study to determine whether, in patients with type 2 diabetes at high risk for cardiovascular and renal events, aliskiren, on top of conventional treatment, reduces cardiovascular and renal morbidity and mortality.
Objective: a) examining whether individual genetic variation in genes relating to drug metabolism, type 2 diabetes with renal and cardiovascular risk, and the drug target pathway confer differential response to aliskiren and b) examining the effect of aliskiren on gene expression in peripheral blood cells in type2 diabetic patients at risk for renal and cardiovascular disease

2.26 mg/mmol and < 22.6 mg/mmol] in at least two of three morning void

fixed combination products must not be used in combination with
angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor
blocker (ARB) in patients with diabetes.
- Specific to the safety follow-up period: Participation in another clinical
trial, whether or not on investigational drug
Other protocol-defined inclusion/exclusion criteria may apply.
