Aliskiren Study of Safety and Efficacy in Senior Hypertensives (ASSESS)

14 avril 2015 mis à jour par: Novartis Pharmaceuticals

A Randomized, Double-blind, Parallel Group, Active-controlled Study to Compare the Systolic Blood Pressure Lowering Efficacy of Aliskiren, Ramipril and a Combination of Aliskiren and Amlodipine, With an Initial 8-week Evaluation, Followed by a 2-3 Year Follow-up to Compare Long-term Safety of an Aliskiren-based Regimen to a Ramipril-based Regimen in Hypertensive Patients ≥ 65 Years of Age

This study is designed to compare the blood pressure lowering efficacy of aliskiren, a combination of aliskiren plus amlodipine, and ramipril in elderly patients with mild to moderate hypertension. It will also compare the long-term safety of an aliskiren-based regimen to a ramipril-based regimen

La description

Inclusion Criteria:

  • Patients ≥ 65 years of age with a clinical diagnosis of essential hypertension at Visit 1.
  • Mean sitting SBP (MSSBP) ≥ 140 mmHg and < 180 mmHg at Visit 2/Visit 201 and Visit 3.
  • Absolute MSSBP difference ≤ 20 mmHg between Visit 3 and the Visit immediately prior

Exclusion Criteria:

  • History of hypersensitivity to any of the study drugs or to drugs of similar chemical classes.
  • Severe hypertension (MSSBP ≥ 180 mmHg or MSDBP ≥ 110 mmHg) at Visit 1, Visit 2, Visit 201 or Visit 3 or during patient self measured blood pressure (SMBP) monitoring in the pre-randomization period confirmed by office measurement.
  • Current treatment with any blocker of the renin angiotensin aldosterone system (RAAS) (aliskiren, ACE inhibitor, angiotensin receptor blocker or an aldosterone antagonist) and unable to discontinue this therapy.
  • Concurrent use of any anti-hypertensive medications except a stable dose of 3 months prior to Visit 1 of alpha adrenergic blockers for benign prostatic hypertrophy (e.g., tamsulosin [Flomax®] for benign prostatic hypertrophy), beta blockers for angina, or beta blocker ophthalmic preparations.
  • Contraindications to aliskiren, ramipril, amlodipine, or hydrochlorothiazide. Other protocol defined inclusion/exclusion criteria apply

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Aliskiren monotherapy
Aliskiren 150 mg, once a day, force titrated to Aliskiren 300 mg after 8 weeks in 50% of patients. Optional addition/titration of amlodipine 5 mg/10 mg and hydrochlorothiazide 12.5/25 mg based on systolic BP control in sequential steps
Aliskiren 150 mg and aliskiren 300 mg tablets will be supplied centrally. These will be blinded with matching placebos for the 2 dose strengths.
Autres noms:
  • Rasilez, Tekturna
Amlodipine 5 mg/10 mg will also be blinded and supplied centrally. For Aliskiren dual therapy arm , Amlodipine is in the regimen; where as for monotherapy arms, Amlodipine is an optional add-on therapy.
Hydrochlorothiazide 12.5 mg/25 mg will be open label and supplied locally. It is an optional add-on to each arm.
Expérimental: Aliskiren dual therapy
Aliskiren 150 mg plus amlodipine 5 mg, once a day, force titrated to Aliskiren 300 mg plus amlodipine 5 mg after 8 weeks in 50% of patients. Optional titration of amlodipine 5 mg to 10 mg and optional addition/titration of hydrochlorothiazide 12.5/25 mg based on systolic BP control in sequential steps
Aliskiren 150 mg and aliskiren 300 mg tablets will be supplied centrally. These will be blinded with matching placebos for the 2 dose strengths.
Autres noms:
  • Rasilez, Tekturna
Amlodipine 5 mg/10 mg will also be blinded and supplied centrally. For Aliskiren dual therapy arm , Amlodipine is in the regimen; where as for monotherapy arms, Amlodipine is an optional add-on therapy.
Hydrochlorothiazide 12.5 mg/25 mg will be open label and supplied locally. It is an optional add-on to each arm.
Comparateur actif: Ramipril monotherapy
Ramipril 5 mg, once a day, force titrated to Ramipril 10 mg after 8 weeks in 50% of patients. Optional addition/titration of amlodipine 5 mg/10 mg and hydrochlorothiazide 12.5/25 mg based on systolic BP control in sequential steps
