This study will compare olmesartan medoxomil to candesartan cilexetil in reducing BNP, a prognostic biomarker of heart failure, at week 24

Condition Intervention Phase
Chronic Heart Failure
High Blood B-type (or Brain) Natriuretic Peptide (BNP) Level
Drug: olmesartan medoxomil + candesartan cilexetil placebo
Drug: olmesartan medoxomil placebo + candesartan cilexetil
Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: A 24-Week Multicentre, Randomized, Double-Blind, Controlled, Parallel Group Non-Inferiority Study to Assess the Efficacy and Safety of Olmesartan Medoxomil Versus Candesartan Cilexetil in Patients With Symptomatic Heart Failure (NYHA II-IV)

Primary Outcome Measures:
  • Absolute BNP change from week 0 to 24 of treatment [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • Proportion of BNP responders at week 4, 8, 16 and 24 (BNP levels reduced to 350 pg/ml or less at all time points) [ Time Frame: 24 weeks maximum ]
  • BNP change from week 0 to week 4, 8, and 16 [ Time Frame: 16 weeks maximum ]
  • Incidence of critical events at 24 weeks: All cause death; Cardiovascular death defined as death due to: HF, myocardial infarction, cardiac arrhythmia, stroke/cerebral vascular accident, other cardiovascular cause (e.g., aneurysm or pulmonary embolism) [ Time Frame: 24 weeks ]
  • Event-free survival [ Time Frame: 24 weeks ]
  • Time-to-death [ Time Frame: 24 weeks ]
  • Time-to-first cardiovascular event [ Time Frame: 24 weeks maximum ]
  • Change in clinical status: Improvement: patient alive without any cardiovascular event with an improvement of at least one NYHA functional class level; No change: patient alive without any cardiovascular event with stable functional NYHA class [ Time Frame: 24 weeks ]

Estimated Enrollment: 400
Study Start Date: June 2008
Study Completion Date: November 2009
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
