A Safety and Effectiveness Study of CNTO 1275 in Patients With Moderate to Severe Plaque-type Psoriasis

March 31, 2015 updated by: Centocor, Inc.

A Phase II, Randomized, Double-blind, Placebo-controlled, Parallel Study of Single and Multiple Dose Regimens With Subcutaneous CNTO 1275 (Human Monoclonal Antibody to IL-12) in Subjects With Moderate to Severe Psoriasis

The purpose of this study is to evaluate the efficacy and safety of initial single and multiple subcutaneous injections of CNTO 1275 in the treatment of patients with moderate to severe plaque psoriasis.

Detailed Description

This is a randomized (the study medication is assigned by chance), double blind (neither physician nor patient knows the treatment that the patient receives), parallel-group, multicenter study to determine the effectiveness and safety of two different doses of CNTO 1275 administered subcutaneously one time or as multiple doses as compared with placebo in patients with moderate to severe plaque-type psoriasis (the most common type of psoriasis). The dose of CNTO 1275 will be 45 or 90 mg administered subcutaneously once or as four weekly doses. Patients who inadequately respond to their treatment may receive one additional dose. Patients will be monitored for the safety throughout the study.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Who Achieved Psoriasis Area and Severity Index (PASI) 75% Improvement at Week 12
Time Frame: Week 12
Psoriasis Area and Severity Index (PASI)(0 [ best] -72 [worst]) score at Week 12. This is a test of how bad a person's psoriasis is. The combination of redness, scaling, and thickness, as well as overall body involvement determine the PASI score.
Week 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Number of Participants Who Achieved Physician's Global Assessment (PGA) Score of Clear (1) or Excellent (2) at Week 12
Time Frame: Week 12
Number of participants achieving a physician global assessment (PGA)(1 [best] to 6 [worst]) score of clear or excellent at Week 12. The PGA is used to determine the participants psoriasis lesions overall at a given time point. Overall lesions will be graded for induration, erythema, and scaling. The sum of the 3 scales will be divided by 3 to obtain a final PGA score.
Week 12
Number of Participants Who Achieved Psoriasis Area Severity Index (PASI) 75% Improvement at Week 32
Time Frame: Week 32
Psoriasis Area and Severity Index (PASI)(0 [ best] -72 [worst]) score at Week 32 for participants who were not retreated at Week 16. This is a test of how bad a person's psoriasis is. The combination of redness, scaling, and thickness, as well as overall body involvement determine the PASI score.
Week 32
Number of Participants Who Achieved Psoriasis Area Severity Index (PASI) 75% Improvement (0-72) at Week 28
Time Frame: Week 28
Psoriasis Area and Severity Index (PASI)(0 [ best] -72 [worst]) score at Week 28 for participants who were retreated at Week 16. This is a test of how bad a person's psoriasis is. The combination of redness, scaling, and thickness, as well as overall body involvement determine the PASI score.
Week 28
