Eligibility

Inclusion Criteria:

Subjects are eligible to be included in the study only if all of the following criteria

apply:

1. Subjects with a chronic moderate to severe plaque-type psoriasis for at least 6 months (as determined by subject interview and confirmation of diagnosis through physical examination by Investigator).

2. Subjects must have moderate to severe nail psoriasis at Screening and Baseline,

defined by:

• mNAPSI score of =20.
• ViSENPsO =3

3. Subjects must have moderate to severe plaque psoriasis at Screening and Baseline,

defined by:

• s-PGA score of at least 3.
• Body Surface Area (BSA) involvement of =10%.
• PASI =12

4. Subjects must be considered candidates for systemic therapy, meaning psoriasis inadequately controlled by topical treatments (corticosteroids), and/or phototherapy, and/or previous systemic therapy. Exclusion Criteria:

Subjects are excluded from the study if any of the following criteria apply:

1. Subjects who have predominantly non-plaque forms of psoriasis, specifically erythrodermic psoriasis, predominantly pustular psoriasis, medication-induced, or medication-exacerbated psoriasis, or new-onset guttate psoriasis.

2. Subjects with ongoing inflammatory skin diseases other than psoriasis or any other disease affecting the fingernails, which may potentially confound the evaluation of study treatment.

3. Subjects with fungal nail infection should be excluded from the study. Subjects in whom the Investigator suspects a fungal nail infection in addition to nail psoriasis should have scrapings sent for direct microscopy and fungal culture. If fungal culture or direct microscopy of nail scrapings turns out to be positive for fungal infection, the subject should be excluded from the study. At the discretion of the investigator, Periodic Acid-Schiff (PAS) staining for nail clippings could also be considered to rule of fungal infection of the nails. Direct microscopy or fungal culture are not required if fungal infection is diagnosed in PAS staining.

4. Subjects with any previous use of tildrakizumab or other IL-23/Th-17 pathway inhibitors, including p40, p19 and IL-17 antagonists for psoriasis.

5. Subjects with known history of allergy or hypersensitivity to any of the inactive ingredients of the Tildrakizumab or placebo formulations.
