An Eight-week Randomized,Double-blind Study to Evaluate the Efficacy and Safety of Fixed-dose Combinations of T80+A5 Versus A5 Monotherapy in Patients With Hypertension Who Fail to Respond Adequately to Treatment With A5 Monotherapy

June 17, 2014 updated by: Boehringer Ingelheim

8 Week Randomised Double-blind Study to Compare the Efficacy and Safety of Telmisartan 80mg+ Amlodipine 5 mg vs. Amlodipine 5mg Monotherapy in Patients With Hypertension Who Fail to Respond Adequately to Treatment With Amlodipine 5mg Monotherapy

The primary objectives of this trial is to demonstrate that the fixed-dose combination of telmisartan 80mg plus amlodipine 5mg (T80/A5) is superior to amlodipine 5mg (A5) in reducing seated trough diastolic blood pressure (DBP) at 8 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion criteria:

  1. diagnosis of essential hypertension
  2. failure to respond adequately to six weeks treatment with amlodipine 5 mg monotherapy
  3. provision of written informed consent

Exclusion criteria:

1. clinical conditions which, in the opinion of the investigator, would not allow safe completion of the protocol and safe administration of telmisartan and amlodipine for the planned duration of this trial (e.g. populations where labeling of either product recommends against its utilization)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
