About this study

This is a randomized (study medication assigned to participants by chance), double-blind (neither the researchers nor the participants know what treatment the participant is receiving), parallel-group, placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect) study. The study consists of Screening Phase (maximum of 42 days prior to Week 0), Treatment Phase (Week 0-12) and Follow-up Phase (up to Week 16). Participants will be randomly assigned to receive JNJ-38518168 (3 milligram [mg] or 30 mg or 60 mg) or placebo once daily. The initial group of the participants will be randomized to either JNJ-38518168 30 mg or placebo. The dose assignments for the subsequent participants will depend on the results of up to 2 interim analyses. Efficacy will be primarily assessed by percentage of participants who achieve a Psoriasis Area and Severity Index (PASI) 75 response at Week 12. Participants' safety will be monitored throughout the study.

Primary outcomes

  1. Percentage of Participants who Achieve Psoriasis Area and Severity Index (PASI) 75 Response at Week 12

    Time frame: Week 12

    The PASI score is a combined assessment of lesion severity and area affected into single score. Body will be divided into 4 sections:head, arms, trunk, and legs. For each section, percent (%) area of skin involved was estimated:0=0%, 1=less than (<) 10%, 2=10 to <30%, 3=30 to <50%, 4=50 to <70%, 5=70 to <90%, 6=90 to 100%. Severity will be estimated by clinical signs:erythema,induration,desquamation;scale:0= none to 4=maximum. Final PASI=sum of severity parameters for each section*area score*weight of section (head:0.1,arms:0.2,body:0.3,legs:0.4);total possible score range: 0=no disease to 72=maximal disease. A PASI 75 response defined as greater than or equal to (>=) 75 % improvement in PASI score from baseline.

Secondary outcomes

  1. Percentage of Participants Who Achieve a Score of 0 or 1 on the Investigator's Global Assessment (IGA) at Week 12

    Time frame: Week 12

    The IGA documents the investigator's assessment of the participants psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling on a scale of 0 to 4 (higher score = more severe). The participant's psoriasis is assessed as 5-point scale as follows: 0=cleared, 1=minimal, 2=mild, 3=moderate, 4=severe.

  2. Percentage of Participants Who Achieve PASI 50, PASI 75, PASI 90 and PASI 100 Responses

    Time frame: Week 0, 2, 4, 6, 8, 12 and 16

    The PASI score is a combined assessment of lesion severity and area affected into single score. Body will be divided into 4 sections:head, arms, trunk, and legs. For each section, % area of skin involved was estimated:0=0%, 1= <10%, 2=10 to <30%, 3=30 to <50%, 4=50 to <70%, 5=70 to <90%, 6=90 to 100%. Severity will be estimated by clinical signs:erythema,induration,desquamation;scale:0= none to 4=maximum. Final PASI=sum of severity parameters for each section*area score*weight of section (head:0.1,arms:0.2,body:0.3,legs:0.4);total possible score range: 0=no disease to 72=maximal disease. A PASI 50, 75, 90, 100 response is defined as corresponding >= 50%, >=75%, >=90%, >=100% improvement in PASI score from baseline.

  3. Percent Improvement From Baseline in PASI Score

    Time frame: Week 0 (Baseline), 2, 4, 6, 8, 12 and 16

    The PASI score is a combined assessment of lesion severity and area affected into single score. Body will be divided into 4 sections:head, arms, trunk, and legs. For each section, % area of skin involved was estimated:0=0%, 1= <10%, 2=10 to <30%, 3=30 to <50%, 4=50 to <70%, 5=70 to <90%, 6=90 to 100%. Severity will be estimated by clinical signs:erythema,induration,desquamation;scale:0= none to 4=maximum. Final PASI=sum of severity parameters for each section*area score*weight of section (head:0.1,arms:0.2,body:0.3,legs:0.4);total possible score range: 0=no disease to 72=maximal disease.

  4. Percentage of Participants Who Achieve Investigator's Global Assessment (IGA) Score Responses of 0, 1 or 2; 0 or 1; and 0

    Time frame: Week 0, 2, 4, 6, 8, 12 and 16

    The IGA documents the investigator's assessment of the participants psoriasis at a given time point. Overall lesions are graded for induration, erythema, and scaling on a scale of 0 to 4 (higher score = more severe). The participant's psoriasis is assessed as 5-point scale as follows: 0=cleared, 1=minimal, 2=mild, 3=moderate, 4=severe.

  5. Change From Baseline in Psoriasis Symptom and Sign Diary (PSSD) Symptom and Sign Score at Week 12

    Time frame: Baseline and Week 12

    The PSSD is a questionnaire designed to measure the severity of psoriasis symptoms and signs over the previous 7 days for the assessment of treatment benefit. The PSSD is a self-administered patient-reported outcome (PRO) instrument that includes 11 items covering symptoms and patient-observable signs. The psoriasis symptom score includes itch (Q1), pain (Q11), stinging (Q10), burning (Q9) and skin tightness (Q4) and average value of all 5 items will be converted into 0-100 score, where 0= least severe to 100=most severe. The psoriasis sign score includes skin dryness (Q2), cracking (Q3), scaling (Q5), shedding or flaking (Q6), redness (Q7) and bleeding (Q8) and average value of all 6 items will be converted into 0-100 score, where 0= least severe to 100=most severe. Total score includes all 11 individual items (both symptom and signs) and average value of all 11 items will be converted into 0-100 score, where 0= least severe to 100=most severe.

  6. Percentage of Participants Who Achieve a PSSD Symptom Score of 0 or PSSD Sign Score of 0 at Week 12

    Time frame: Week 12

    The PSSD is a questionnaire designed to measure the severity of psoriasis symptoms and signs over the previous 7 days for the assessment of treatment benefit.

The psoriasis sign score includes skin dryness (Q2), cracking (Q3), scaling (Q5), shedding or flaking (Q6), redness (Q7) and bleeding (Q8) and average value of all 6 items will be converted into 0-100 score, where 0= least severe to 100=most severe. Total score includes all 11 individual items (both symptom and signs) and average value of all 11 items will be converted into 0-100 score, where 0= least severe to 100=most severe.
