Name Time Method Number of Participants with Presence of Blood Inflammatory Biomarkers at Week 12 Week 12 Inflammatory biomarkers will be assessed using blood serum/plasma sample collected for local safety analysis.
Number of Participants with Presence of Skin Inflammatory Biomarkers at Week 48 or End of Study (EOS) up to Week 48 Inflammatory biomarkers will be assessed using a small piece of 4 millimeter (mm) of skin biopsy sample collected at Week 48 or until the date of initiation of any systemic therapy including phototherapy whichever comes first (EOS) (stored in RNAlater solution).
Percentage of Participants Who Experienced Psoriasis Relapse Baseline up to Week 96/ End of study (EOS) Psoriasis Area and Severity Index (PASI) is a combination of the intensity of psoriasis, assessed by the erythema (reddening), induration (plaque thickness) and scaling on a scale range from 0 (no symptoms) to 4 (very marked), together with the percentage (%) of the area affected, rated on a scale from 0 (0%) to 6 (90-100%). PASI scoring is performed at four body areas, the head, arms, trunk, and legs. The total PASI score ranges from 0 (no psoriasis) to 72 (the most severe disease). Relapse is defined using the following thresholds: PASI greater than (\>) 3 (participants who had a PASI lesser than or equal to \[\<=\] 3 at baseline); PASI \> 5 (participants who had a PASI \<= 5 at baseline); DLQI \> 5 (participants who had a DLQI \<= 5 at baseline); Initiation of any topical drug/medication for psoriasis; Initiation of any systemic therapy for psoriasis (biologic or non-biologic).

Name Time Method Time to Psoriasis Relapse Baseline up to Week 96(EOS) Time to relapse is defined as the time interval between the last administration of Tildrakizumab and the relapse of psoriasis in days.
Absolute Psoriasis Area and Severity Index (PASI) Scores Baseline, Weeks 12, 24, 36, 48, 60, 72, 84 and Week 96/ End of study (EOS) The PASI is a combination of the intensity of psoriasis, assessed by the erythema (reddening), induration (plaque thickness) and scaling on a scale range from 0 (no symptoms) to 4 (very marked), together with the percentage (%) of the area affected, rated on a scale from 0 (0%) to 6 (90-100%). PASI scoring is performed at four body areas, the head, arms, trunk, and legs. The total PASI score ranges from 0 (no psoriasis) to 72 (the most severe disease).
Change from Baseline in Absolute Psoriasis Area and Severity Index (PASI) Scores Baseline, Weeks 12, 24, 36, 48, 60, 72, 84 and Week 96/ End of study (EOS) The PASI is a combination of the intensity of psoriasis, assessed by the erythema (reddening), induration (plaque thickness) and scaling on a scale range from 0 (no symptoms) to 4 (very marked), together with the percentage (%) of the area affected, rated on a scale from 0 (0%) to 6 (90-100%). PASI scoring is performed at four body areas, the head, arms, trunk, and legs. The total PASI score ranges from 0 (no psoriasis) to 72 (the most severe disease). Change from baseline will be calculated by subtracting post-dose value from baseline value.
Absolute Body Surface Area (BSA) Scores Baseline, Weeks 12, 24, 36, 48, 60, 72, 84 and Week 96/ End of study (EOS) The BSA is a numerical score used to measure the total area of the body affected by psoriasis. The palm method will be applied: the participant's palm, including the five digits is used as a reference (representing approximately 1% of the total body surface area) and is used to repeatedly cover the lesions on the body. The investigator totals the number of palms required and then estimates the percentage (%) in each of the four body regions: head (including scalp) and neck (10%); upper extremities (20%); trunk (30%); and lower extremities (40%).

It is composed of 10 items related to symptoms, feelings, daily activities, leisure, working or studying activities, personal relationships and opinions about dermatological treatment. Each item is scored from 0 (not affected at all) to 3 (very much affected). The DLQI score is the sum of the 10 individual question scores and ranges from 0 (no effect at all on participant's life) to 30 (extremely large effect on participant's life), with lower scores indicating better quality of life.

DLQI-R is a scoring modification involves multiplying the original DLQI score by a conversion factor that increases with the number of not relevant responses.
