About this study

Official title: A Multicenter, Double-Blind, Placebo-Controlled, Dose-Ranging Study to Assess the Efficacy and Safety of Doxercalciferol Capsules in the Treatment of Subjects With Moderate to Severe Chronic Plaque Psoriasis

The purpose of this study was to evaluate the safety and effectiveness of an investigational drug called doxercalciferol in participants with moderate to severe chronic plaque psoriasis, in comparison with a placebo ("sugar pill"). All study related care was provided including doctor visits, physical exams, laboratory tests and study medication. Total length of participation was 28 weeks.

Read the detailed description

This was a multicenter, randomized, double-blind, placebo-controlled, dose-ranging, parallel group study to evaluate the efficacy and safety of doxercalciferol given orally, once daily for 24 weeks to participants with moderate to severe chronic plaque psoriasis. Participants were randomized and stratified by site and Psoriasis Area Severity Index (PASI) score to one of three active treatment groups or to the placebo group.

What is being measured

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

  1. Percentage of Participants With at Least 50 Percent (%) Reduction in Psoriasis Area Severity Index (PASI) Score at Week 12 or Early Termination

    PASI score: range: 0 (no disease) to 72 (maximal disease). Body was divided into head (h), trunk (t), upper (u) and lower (l) extremities. For each section, percent area of skin involved (A) was estimated: 1 (<10%) to 6 (90% - 100%), and severity was estimated by clinical signs: (erythema [E], induration [I], and desquamation [D]) on a scale: 0=no symptoms, 4=very marked. PASI score= 0.1 (E[h] + I[h] + D[h]) A[h] + 0.2 (E[u] + I[u] + D[u]) A[u] + 0.3 (E[t] + I[t] + D[t]) A[t] + 0.4 (E[l] + l[I] + D[l]) A[l].

    Measured: Week 12 or Early Termination

Secondary outcomes (2)
  1. Percentage of Participants With at Least 50 Percent (%) Reduction in Psoriasis Area Severity Index (PASI) Score at Week 24 or Early Termination

    PASI score: range: 0 (no disease) to 72 (maximal disease). Body was divided into head (h), trunk (t), upper (u) and lower (l) extremities. For each section, percent area of skin involved (A) was estimated: 1 (<10%) to 6 (90% - 100%), and severity was estimated by clinical signs: (erythema [E], induration [I], and desquamation [D]) on a scale: 0=no symptoms, 4=very marked. PASI score= 0.1 (E[h] + I[h] + D[h]) A[h] + 0.2 (E[u] + I[u] + D[u]) A[u] + 0.3 (E[t] + I[t] + D[t]) A[t] + 0.4 (E[l] + l[I] + D[l]) A[l].

    Measured: Week 24 or Early Termination

  2. Percentage of Participants With Static Physician's Global Assessment (PGA) Score of Clear or Almost Clear at Week 12, 24 or Early Termination

    Static PGA of psoriasis is scored on a 5-point scale (0 = clear to 4 = severe), reflecting a global consideration of the erythema, induration and scaling across all psoriatic lesions. Clear (erythema: no, scale: no, induration: no thickness); Almost Clear (erythema: light pink, scale: fine scale, induration: barely palpable); Mild (erythema: light red, scale: coarse scale on most lesions, induration: slight but visible elevation, indistinct edges); Moderate (erythema: red, scale: coarse adherent scale predominates, induration: moderate elevation with edges); and Severe (erythema: dark red to purple, scale: thickened adherent scale, induration: marked thickness distinct and pronounced edges). Percentage of participants with static PGA score of clear or almost clear are reported.

    Measured: Week 12 or Early Termination, Week 24 or Early Termination

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Doxercalciferol in people with Moderate to Severe Chronic Plaque Psoriasis, run by Genzyme, a Sanofi Company at 19 sites in United States.

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 5 inclusion and 21 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 5 May 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 19 sites in United States. 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 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?

Yes. Results are posted in the registry (first posted 5 May 2014). 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?

Percentage of Participants With at Least 50 Percent (%) Reduction in Psoriasis Area Severity Index (PASI) Score at Week 12 or Early Termination (time frame: Week 12 or Early Termination). 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 5 May 2014.
