Low-dose Nifedipine-Valsartan Combination Compared to Up-titrated Valsartan Monotherapy in Essential Hypertension

June 4, 2014 updated by: Bayer

Randomized,Open-label,Parallel Design Comparator Study of Effect of Nifedipine GITS/OROS (Adalat) 30 mg in Combination With Valsartan (Diovan) 80 mg Compared to Valsartan (Diovan) 160 mg Monotherapy in Patients Whose Blood Pressure is Not Well Controlled by Valsartan 80 mg Alone

This will be a multi-center, prospective, randomized, open-label, parallel design, two arm comparator trial. In the proposed study, the investigators will compare low-dose combination therapy of Nifedipine GITS/OROS plus Valsartan with up-titrated monotherapy of Valsartan with respect to their blood pressure-decreasing effects in patients with essential hypertension.The study consists of a screening visit, followed by randomization and administration of either Nifedipine GITS/OROS 30 mg in combination with Valsartan 80 mg or Valsartan 160 mg for 12 weeks of treatment.The primary efficacy parameters will be mean SBP and DBP on office BP monitoring at 12 weeks of treatment compared to baseline.

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). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All
