Description of intervention(s) / exposure
Efficacy of Tildrakizumab in adults with moderate-to-severe plaque psoriasis will be evaluated through photographic analysis from baseline to week 64.

Patients will be receiving Tildrakizumab every 12 weeks following two loading doses 4 weeks apart, by the decision of the treating physician (prior to offering this trial). Week 0 will coincide with the first loading dose, and the second will occur at Week 4, both in clinic. Subsequent observation sessions will occur immediately following administration of Tildrakizumab as scheduled.

Observational study visits will occur at scheduled visited at Week 0,4,8,16,28,40,52 and 64 with each visit requiring time to review any adverse events, concomitant medication collection, vital signs, targeted physical examination, quality of life questionnaires and full body photography administered by treating dermatologist. Each scheduled visit should take no longer than approximately 120 minutes.

Patients that chose to not enrol or are ineligible are required to be PBS-approved in order to receive Tildrakizumab treatment.

Summary
Brief summary
Plaque psoriasis is a multifaceted immunological condition primarily resulting from a dysfunctional immune response with T-cells at the center of immunogenesis.

Who is it for?
You may be eligible for this study if you are an adult who has been diagnosed with moderate to severe plaque psoriasis and your treating physician has prescribed you Tildrakizumab. Your treating physician will have prescribed two loading doses of Tildrakizumab 4 weeks apart.

Study details:
This is an observational study that uses high quality photography and investigator assessments to determine changes to plaque psoriasis over a period of 64 weeks (Study visits will be conducted at week 0,4,8,16,28,40,52 and 64.).

The aim of the study is to evaluate the efficacy of Tildrakizumab in the resolution/treatment of psoriasis.
