About this study

Official title: A Phase 3, Multicenter, Randomized, Double-blind, Placebo-controlled Study Evaluating the Efficacy and Safety of Ustekinumab in the Treatment of Korean and Taiwanese Subjects With Moderate to Severe Plaque-type Psoriasis

The purpose of this study is to evaluate the efficacy and safety of Ustekinumab in the treatment of patients with moderate to severe psoriasis in South Korea and Taiwan.

Read the detailed description

This is phase 3, multicenter, randomized, placebo-controlled double-blind, parallel study of subcutaneous injection of placebo and ustekinumab 45mg in Taiwanese and Korean patients with moderate to severe plaque psoriasis. Ustekinumab is an experimental medicine that is being tested to see if it may be useful in treating moderate to severe psoriasis. The patients will receive either ustekinumab or placebo at week 0 or week 4, and will be followed up through week 36. Patients who randomized (study drug assigned by chance) to placebo will cross over to ustekinumab 45mg group at week 12 and week 16 .The effectiveness of ustekinumab will be compared with placebo treated patients at week 12. Safety information will be collected through week 36. Patients randomized to ustekinumab will receive placebo at week 12 to maintain the blind and additional dose of 45mg at week 16. This study will be conducted in approximately 13 sites in South Korea and Taiwan and will include approximately 120 patients with approximately 60 patients in each country. This study is "blinded." This means that neither you nor your study doctor will know in which group you are placed. However, in case of medical emergency, your study doctor can quickly find out which treatment group you are in. You may get either ustekinumab or placebo (which looks like the medicine being studied but has no active ingredients) at the start of the study. All patients in the study will eventually receive Ustekinumab after week 12. Patients assigned to the ustekinumab will receive 45 mg subcutaneously at weeks 0, 4 and 16; and placebo at week 12. Patiens assigned to placebo will receive subcutaneous injections of placebo at weeks 0 and 4; then crossover to 45 mg of ustekinumab at weeks 12 and 16. Duration of study participation up to 36 weeks.

What is being measured

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

  1. The Number of Patients Who Achieved at Least a 75% Improvement in PASI (Psoriasis Area and Severity Index) at Week 12

    PASI score can range from 0 (no psoriasis) to 72 (severe psoriasis).

    Measured: Week 12

Secondary outcomes (2)
  1. The Number of Patients With a Physician's Global Assessment (PGA) Score of Cleared (0) or Minimal (1) at Week 12

    Measured: Week 12

  2. The Change in Dermatology Life Quality Index (DLQI) From Baseline at Week 12

    Scores could range from 0 to 30. A lower DLQI score represents better quality of life.

    Measured: Baseline to Week 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Ustekinumab 45 mg - CP and Ustekinumab 45 mg - after CP in people with Psoriasis, run by Centocor, Inc. at 5 sites in 2 countries.

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 7 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 29 Mar 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in Taiwan, South Korea. 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. Some participants in this study may receive a placebo. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Oct 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Number of Patients Who Achieved at Least a 75% Improvement in PASI (Psoriasis Area and Severity Index) at Week 12 (time frame: Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 29 Mar 2013; AzTrials last refreshed its copy on 7 Nov 2026.
