About this study

Official title: Efficacy and Safety of Two Fixed-combination Antihypertensive Regimens, Amtrel® and Co-Diovan® in Type 2 Diabetes Hypertension Patients With Microalbuminuria

The purpose of the study is to compare the change from baseline in blood pressures (DBP/SBP) to 16-week regimen between Amtrel® and Co-Diovan®. The secondary objectives were listed as the following.

  • To compare the response rate (defined as SBP < 130 mmHg and DBP < 80 mmHg) at the end of study
  • To evaluate the change from baseline in albumin-to-creatinine ratio with antihypertensive medications in whole group (combined treatment groups) and each treatment group (Amtrel®, Co-Diovan®) at Week 16
  • The change from baseline in glycosylated hemoglobin (HbA1c) at Week 16
  • The change from baseline in fasting plasma glucose (FPG) at Week 16
  • The change from baseline in fasting lipid profiles (triglyceride, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol) at Week 16
  • The change from baseline in arteriosclerosis marker (brachial-ankle pulse-wave velocity (ba-PWV) and ankle-brachial pressure index (ABI), using Colin-VP1000) at Week 16
  • The change from baseline on the body mass index (BMI) and waist-hip ratio (WHR) at each specified study time point
  • To ascertain the safety and tolerability of Amtrel® versus Co-Diovan® including AE/SAE, and laboratory examinations
Read the detailed description

At the screening visit, patients who fulfilled the entrance criteria and had given written informed consent entered a placebo running period where they discontinued antihypertensive medication for two weeks. During that period, Adalat 5mg could be given for emergency. At the end of placebo running period those patients became hypertensive (i.e., SBP between 130-180mmHg or DBP between 80-110mmHg) were randomized into either treatment group. For those patients remaining normotensive continued to be on placebo run-in for another two weeks (10 - 14 days). After the two-week (10 - 14 days) placebo run-in period those patients became hypertensive were randomized into either treatment group. However for those patients remaining normotensive were excluded from the study. After randomization into either arm, patients entered four months treatment period. The dosage adjustment were proceed in order to reach the best effect. During the treatment period there was a monthly visit to assess the response of the patients.

The starting dose of Amtrel® was 1 capsule (contains 1/2 tablet) (amlodipine / benazepril hydrochloride 2.5 mg/ 5 mg) every morning and could be adjusted up to 2 capsules (contains 1 tablet per capsule) (amlodipine / benazepril hydrochloride 10 mg/ 20 mg) every morning if patients did not achieve the criteria of SBP<130 mmHg and DBP< 80 mmHg during treatment period.

The starting dose of Co-Diovan® was 1 capsule (contains 1/2 tablet) (valsartan/ hydrochlorothiazide 40 mg/ 6.25 mg) every morning and could be adjusted up to 2 capsules (contains 1 tablet per capsule) (valsartan/ hydrochlorothiazide 160 mg/ 25.0 mg) every morning if patients did not achieve the criteria of SBP<130 mmHg and DBP< 80 mmHg during treatment period.

All randomized patients attended monthly clinic visits for the 16-week treatment period. At week 4 (Visit 3), all patients were force-titrated to 1 capsule (1 tablet per capsule) for 4 weeks. Subsequently, those patients did not achieve the target blood pressure (SBP<130 mmHg and DBP<80 mmHg) were titrated monthly to next dose level (2 capsule per day).

What is this clinical trial studying?

A Phase 4 study testing Amlodipine+Benazepril and Valsartan+Hydrochlorothiazide in people with Hypertension and Diabetes Mellitus, Type 2, run by TSH Biopharm Corporation Limited at 4 sites in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 17 Jun 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To compare the change from baseline in blood pressures (DBP/SBP) to 16-week regimen between Amtrel® and Co-Diovan® (time frame: 16-week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01375322, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Jun 2011.
