About this study

Official title: Azelnidipine and Amlodipine Anti-Coronary Atherosclerotic Trial in Hypertensive Patients Undergoing Coronary Intervention by Serial Volumetric Intravascular Ultrasound Analysis in Junten Medical University (ALPS-J)

In patients with hypertension who undergo elective PCI, the effects of long-term administration of Calblock (azelnidipine) on plaque volume will be determined quantitatively by 3D-IVUS and compared with those of amlodipine besilate (Norvasc or Amlodin).

Read the detailed description

Clinical studies have demonstrated that calcium antagonists can reduce cardiovascular events in patients with coronary artery disease. Recently, suppression of the development of coronary atherosclerotic plaque by calcium antagonists has been reported as one of the mechanisms involved. Thus, calcium antagonists have been promising strategy for preventing the progression of the coronary atherosclerosis. Various calcium antagonists are clinically available at present and these drugs may differ from each other with respect to the anti-atherosclerotic effects. Consequently, we plan to perform the ALPS-J study to compare the effects of two long-acting calcium antagonists, azelnidipine and amlodipine, on plaque quantitatively by IVUS. In this study, azelnidipine (16 mg/day) or amlodipine besilate (5 mg/day) will be administered to patients with hypertension for 48 weeks after elective PCI. The plaque volume will be measured in each patient by IVUS at the time of PCI and 48 weeks after PCI. Percent change in plaque volume from the baseline value will be used as the primary endpoints for evaluation of efficacy. We plan to enroll 100 patients in each group for a total of 200 patients.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percent change in plaque volume from the baseline value. (IVUS) Percent change in plaque volume = (plaque volume after 48 weeks of drug administration - baseline plaque volume) / baseline plaque volume

    Measured: 48Weeks

Secondary outcomes (3)
  1. Change of plaque volume from the baseline value. (IVUS) Amount change and percent change in Minimal lumen diameter and % stenosis. (Quantitative Coronary Analysis) Change of intimal thickening volume in-stent.

    Measured: 48Weeks

  2. Correlativity of plaque volume and inflammatory laboratory parameters (hs-CRP, MCP-1, PTX-3) Correlativity of laboratory parameters and blood pressure. Correlativity of plaque volume and antioxidant laboratory parameters (LPO, 8-isoprostane)

    Measured: 48Weeks

  3. The following treatments and incidence of events, Changes from baseline of laboratory parameters (TC, LDL-C,TG, HDL-C, hs-CRP, MCP-1, LPO, 8-isoprostane, PTX-3) after 48 weeks of drug administration. Correlativity of plaque volume and blood pressure.

    Measured: 48Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Calcium channel blockers (amlodipine, azelnidipine) in people with Hypertension and Coronary Atherosclerosis, run by Juntendo University at 1 site in Japan.

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 6 inclusion and 8 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 14 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. 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?

Percent change in plaque volume from the baseline value. (IVUS) Percent change in plaque volume = (plaque volume after 48 weeks of drug administration - baseline plaque volume) / baseline plaque volume (time frame: 48Weeks). 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 NCT00294567, which also lists 2 linked publications.

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 14 May 2021; AzTrials last refreshed its copy on 8 Nov 2026.
