Descrizione dettagliata
Although numerous therapeutic options exist for the treatment of psoriasis, there is still a significant unmet medical need due to the limited effectiveness and/or significant side effect profile of current treatment options. Preclinical studies and early phase clinical studies suggest that interleukins-12 and -23, two molecules that are part of the communication network in the immune system, may play an important role in psoriasis. Ustekinumab (CNTO 1275) is a monoclonal antibody directed against interleukins -12 and -23. This is a randomized (study drug assigned by chance like flipping a coin), double blind (neither physician nor patient knows the name of the assigned drug), parallel-group, multicenter study to determine the effectiveness and safety of two different doses of ustekinumab (CNTO 1275) administered subcutaneously (under the skin) as compared with placebo in patients with moderate to severe plaque-type psoriasis (the most common type of psoriasis). The hypothesis is that ustekinumab (CNTO 1275) will be more effective in treatment of psoriasis than placebo, that the improvement in psoriasis will result in an improved quality of life for treated patients and that ustekinumab (CNTO 1275) will be generally well tolerated. Patients will receive ustekinumab (CNTO 1275), 45 or 90 mg, or placebo administered subcutaneously at weeks 0 and 4 weeks then every 12 weeks thereafter until week 52. For patients who partially respond to the starting regimen, the dosing interval may be adjusted to every 8 weeks. Patients will enter long term extension portion of the study at week 52 during which patients will continue to receive treatment with ustekinumab (CNTO 1275) and will be followed for a total of up to 264 weeks from the initial (week 0) administration of study agent.
The dose of ustekinumab (CNTO 1275) will be 45 or 90 mg or placebo administered subcutaneously at weeks 0 and 4 weeks then every 12 weeks thereafter. For patients who partially respond to the starting regimen, the dosing interval may be adjusted to every 8 weeks.

Misure di risultato primarie
Misura del risultato |
Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Number of Participants With Psoriasis Area and Severity Index (PASI) Score of 75 Percent or Above at Week 12
Lasso di tempo: Week 0 to Week 12
|
Number of participants achieving greater than or equal to 75 percent improvement in PASI at Week 12. PASI is a widely used tool for the measurement of severity of psoriasis.
This is a test of how bad a person's psoriasis is.
The scale combines redness, scaling, and thickness, as well as overall body involvement to determine the PASI score.
The scale ranges from 0 (best) to 72 (worst).

Misura Descrizione |
Lasso di tempo |
|---|---|---|
|
Number of Participants With Physician Global Assessment (PGA) of Cleared or Minimal at Week 12
Lasso di tempo: Week 12
|
Number of participants achieving a physician global assessment (PGA) (0 [none] to 5 [severe]) of cleared or minimal at Week 12.
The PGA is 7-point scale used in clinical trials of various diseases.
In this the physician checks the state of the disease and gives them score from 0 (clear) to 5 (severe).

|
Change in Dermatology Life Quality Index (DLQI) at Week 12
Lasso di tempo: Baseline to Week 12
|
Change in Dermatology Life Quality Index (DLQI) from baseline at Week 12.
The DLQI is a 10-item questionnaire, that in addition to evaluating overall quality of life, can be used to assess 6 different aspects that may affect quality of life: symptoms and feelings, daily activities, leisure, work or school performance, personal relationships, and treatment.
Scores range from 0 (no impairment in quality of life) to 30 (most impairment in quality of life).

Number of visits at which participants randomized at Week 28 achieved at least 75 percent improvement from baseline in PASI from Week 40 through Week 52 in participants randomized at Week 28.
PASI is a widely used tool for the measurement of severity of psoriasis.
This is a test of how bad a person's psoriasis is.
The scale combines redness, scaling, and thickness, as well as overall body involvement to determine the PASI score.
