About this study
Official title: A Phase IIa Randomized, Double-blind, Placebo-Controlled, Parallel Group, Multi-Center, Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of RWJ-445380 Administered to Patients With Plaque Psoriasis
The primary objective of the study is to evaluate the safety and tolerability of 50, 100, 200, and 300 mg/day doses of RWJ-445380 for up to 12 weeks in patients with plaque psoriasis
Read the detailed description
Trials with a new, first-in-class drug will be done to ascertain safety, tolerability, absorption and other effects in the treatment of psoriasis, such as effects on biomarkers. Approximately 60 adult patients with psoriasis covering at least 3 percent of their body surface area will be recruited for the study. They will be randomly assigned to one of 5 treatment arms each patient has an equal chance of receiving the placebo, 50 mg, 100 mg, 200 mg, or 300 mg dose. Patients will receive study medication in a blinded fashion, i.e, the patient, the doctor and the study sponsor will not know what group the patient is in until all patients complete the study. Patients will take the medication daily for 12 weeks. The study will be enrolled in two enrollment groups of about 30 patients each, so that extent of side effects can be ascertained and expectations on their extent confirmed. The investigator and the sponsor will monitor the study for the occurrence of possible side effects. In addition to a screening visit, patients will have visits every week for the first month, and then every two weeks until 12 weeks of treatment. At 12 weeks, there are 2 visits on consecutive days for tests and there is one followup visit 4 weeks after the last dose of study drug is taken.
Medical history, physical examination, blood pressure and heart rate, and ECGs are checked periodically. Blood samples will be taken for standard laboratory tests as well as special tests of the drug blood level, biomarkers to see whether the drug might be affecting the biological pathway of antigen presentation, and skin biopsies from areas both involved and not involved with psoriasis. The blood and skin samples will be used to see whether some of the characteristics of psoriasis are changed by taking the drug. Samples will also be taken to see whether certain types of immune cells are affected by taking the drug. Immunizations with tetanus and hepatitis A vaccines will be done to see if taking the drug might affect immune responses to these agents. Patients will receive RWJ-445380, 50, 100, 200, 300 mg, or placebo. Patients will receive an oral capsule daily for up to 12 weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing RWJ-445380 in people with Chronic Small Plaque Psoriasis, run by Alza Corporation, DE, USA.
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 2 inclusion and 2 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 18 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.
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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Evaluate the safety of RWJ-445380 for up to 12 weeks; assessing adverse events, vital signs, laboratory assessments, physical exam and ECGs in patients with psoriasis. 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 18 Feb 2011; AzTrials last refreshed its copy on 7 Nov 2026.
