This study is being conducted to evaluate the efficacy and safety/tolerability of tildrakizumab (SCH 900222/MK-3222) in a population of participants with moderate-to-severe plaque psoriasis. The primary hypotheses of the study are that tildrakizumab is superior to placebo in the treatment of moderate-to-severe chronic plaque psoriasis as measured by the proportion of participants achieving >= Psoriasis Area Sensitivity Index of 75% (PASI-75) response and the proportion of participants with a Physician's Global Assessment (PGA) score of "clear" or "minimal" with at least a 2 grade reduction from baseline at Week 12.

Phase 3
The base study consists of a screening phase of up to 4 weeks followed by a treatment period of 52 weeks, and a 20-week follow-up period. The base study treatment period is divided into 3 sequential parts.
In Part 1 of the base study (Week 0 to Week 12), participants will be randomized to one of 4 study arms (Arm A: tildrakizumab 200 mg + matching placebo to etanercept; Arm B: tildrakizumab 100 mg + matching placebo to etanercept; Arm C: matching placebo to tildrakizumab + matching placebo to etanercept; Arm D: matching placebo to tildrakizumab + etanercept 50 mg).
In Part 2 of the base study (Week 12 to Week 28), participants in Arm A and Arm B will receive matching placebo to tildrakizumab to maintain blinding at Week 12 and will receive either tildrakizumab 200 mg (Arm A) or tildrakizumab 100 mg (Arm B) at Weeks 12 and 16. Participants in Arm A and Arm B will also receive matching placebo to etanercept once weekly through study Week 28. At study Week 12, Arm C participants will be re-randomized to receive their first dose of tildrakizumab 200 mg or tildrakizumab 100 mg, and will receive additional doses of study medication according to their re-randomized treatment assignment at Week 16. Participants in Arm C will also receive matching placebo to etanercept through treatment Week 28. Participants in Arm D will continue with once weekly doses of etanercept through study Week 28 in combination with matching placebo to tildrakizumab.
In Part 3 of the base study (Week 28 to Week 52), participants in Arm A with >= PASI-75 response at Week 28 will be re-randomized to either continue tildrakizumab 200 mg or receive tildrakizumab 100 mg at study Weeks 28, 40, and 52. Participants with >= PASI-50 response but < PASI-75 response will continue to receive tildrakizumab 200 mg every 12 weeks and those participants with < PASI-50 response will be discontinued from the study. Participants in Arm B with >= PASI-75 response at Week 28 will continue to receive tildrakizumab 100 mg every 12 weeks. Those with >= PASI-50 response but < PASI-75 response will be re-randomized to receive continued tildrakizumab 100 mg or tildrakizumab 200 mg every 12 weeks. Participants in Arm B with < PASI-50 response will be discontinued from the study. Participants in Arm C will continue to receive treatment every 12 weeks according to their re-randomized treatment assignment. Participants in Arm D that achieve >= PASI-75 response at Week 28 will be discontinued from the study. Those participants with < PASI-75 response at Week 28 will be crossed over to tildrakizumab 200 mg to receive doses at Weeks 32, 36 and 48.
Eligible participants that choose to enroll in the extension study will have an additional treatment period of up to 192 weeks and will be monitored for an additional 20 weeks in the follow-up period. Each participant will receive tildrakizumab 200 mg or tildrakizumab 100 mg every 12 weeks up to study Week 244 according to their treatment assignment at the conclusion of Part 3 of the base study.

Time frame: Week 12
The PASI is a measure of the average redness, thickness, and scaliness of lesions (each graded on a 0-4 scale), weighed by the area of involvement. Calculated PASI score ranges from 0 to 72, with higher score indicating more severe disease status. The PASI-75 response indicates the number of participants achieving a 75% reduction in PASI score compared to baseline. Statistical analyses presented below compare tildrakizumab to placebo to support the primary hypothesis of the study.
Time frame: Week 12
The PGA is used to determine the overall severity of a participant's psoriasis lesions at a given time point. Overall lesions will be graded for thickness, erythema, and scaling on a scale from 0 to 5. The sum of the 3 scales will be divided by 3 to obtain the PGA score. PGA is assessed as: 0= Cleared, except for residual discoloration. 1= Minimal, majority of lesions have individual scores that average 1. 2 =Mild, majority of lesions have individual scores that average 2. 3= Moderate, majority of lesions have individual scores that average 3. 4= Marked, majority of lesions have individual scores that average 4. 5= Severe, majority of lesions have individual scores that average 5. Statistical analyses presented below compare tildrakizumab to placebo to support the primary hypothesis of the study.

An adverse event is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment.
