Official Title:	A 54 Week, Randomized, Double-Blind, Parallel-Group, Multicenter Study Evaluating the Long-Term Gastrointestinal (GI) Safety and Tolerability of Aliskiren (300 mg) Compared to Ramipril (10 mg) in Patients With Essential Hypertension

Further study details as provided by Novartis:

Primary Outcome Measures:

Occurrence of colonic pathology as defined by the composite endpoint (hyperplastic polyps, inflammatory polyps, adenomatous polyps or carcinomas) after one year of treatment with an aliskiren-based regimen compared to a ramipril-based regimen [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

To assess mucosal hyperplasia, dysplasia, and severity of inflammation in rectal and cecal mucosal biopsy specimens obtained at baseline and following one-year of treatment with an aliskiren-based regimen compared to a ramipril-based regimen [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
To assess the occurrence of the individual components of the composite endpoint following one-year of treatment with an aliskiren-based regimen compared to a ramipril-based regimen. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
To assess the number of each component of the composite endpoint following one-year of treatment with an aliskiren-based regimen compared to a ramipril-based regimen. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]
To evaluate the overall gastrointestinal tolerability following one-year of treatment with an aliskiren-based regimen compared to a ramipril-based regimen. [ Time Frame: 1 year ] [ Designated as safety issue: Yes ]

Estimated Enrollment:	640
Study Start Date:	February 2008

Criteria

Inclusion Criteria:

Male or female outpatients, 50 years of age and older with a diagnosis of essential hypertension
Successful high quality colonoscopy at baseline including visualization of the entire colon and the cecum as confirmed by a photograph and collection of the rectal and cecal mucosal biopsy samples
All rectal, colon or cecal polyps found at baseline colonoscopy must be completely resected endoscopically at the time of the procedure.
