26-week Open Study of telmisartan40mg+amlodipine10mg or telmisartan80mg+amlodipine10 mg in Hypertension

An Open Label Trial of the Efficacy and Safety of Chronic Administration of the Fixed Dose Combination of Telmisartan 40mg + Amlodipine 10mg or Fixed Dose Combination of Telmisartan 80mg + Amlodipine 10mg Tablets Alone or in Combination With Other Antihypertensive Medications in Patients With Hypertension

The primary objective of this trial is to assess the efficacy and safety of the fixed dose combinations telmisartan 40mg/amlodipine 10mg (T40/A10) or telmisartan 80mg/amlodipine 10mg (T80/A10) during open-label treatment for at least six months.

An additional objective is to assess the efficacy and safety of concomitant administration of either T40/A10 or T80/A10 with any other therapies commonly used in the treatment of hypertension.

The primary endpoint is the proportion of patients achieving DBP control (defined as mean seated DBP < 90 mmHg at trough i.e. approximately 24 hours after last dose of study treatment) at six months of treatment or at last trough observation during the treatment period (i.e. last trough observation carried forward).

Inclusion Criteria:

• discontinuation from the preceding trial.
• known or suspected secondary hypertension.
• mean seated systolic blood pressure (SBP) >= 180 mmHg and/or mean seated diastolic blood pressure (DBP) >= 120 mmHg at any visit.

• administration of ARBs or dihydropyridine CCBs (apart from trial medication). any other clinical condition which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan and amlodipine.
