What researchers measure

Primary outcomes

  1. Proportion of patients achieving an absolute Psoriasis Area Severity Index (aPASI) score ≤ 3 at Week 24 or nearest visit

    Time frame: Approximately 24 weeks after treatment initiation (data to be collected at visit nearest to this timepoint)

Secondary outcomes

  1. Effectiveness of deucravacitinib treatment measured by the number of participants who achieve an absolute Psoriasis Area Severity Index (aPASI) score ≤ 3 and ≤ 6

    Time frame: 5 years

  2. Effectiveness of deucravacitinib treatment measured by the number of participants who achieve Psoriasis Area Severity Index (PASI) 75/90/100

    Time frame: 5 years

  3. Effectiveness of deucravacitinib treatment measured by the number of participants who achieved static Physician's Global Assessment (sPGA) 0/1 and change in sPGA over time

    Time frame: 5 years

  4. Effectiveness of deucravacitinib treatment measured by body surface area (BSA) affected by psoriasis and changes in BSA from baseline and over time

    Time frame: 5 years

  5. Effectiveness of deucravacitinib treatment in sensitive body areas measured by Physician's Global Assessment (PGA) for the genital area

    Time frame: 5 years

  6. Effectiveness of deucravacitinib treatment in sensitive body areas measured by Physician's Global Assessment (PGA) for the intertriginous areas

    Including but not limited to axilla, popliteal fossa, inguinal, genital, submammary, anal region

    Time frame: 5 years

  7. Effectiveness of deucravacitinib treatment in sensitive body areas measured by palmoplantar psoriasis Physician's Global Assessment (pp-PGA) for the palmoplantar area

    Time frame: 5 years

  8. Effectiveness of deucravacitinib treatment in sensitive body areas measured by target Nail Psoriasis Severity Index (NAPSI) for the nails

    Time frame: 5 years

  9. Effectiveness of deucravacitinib treatment in sensitive body areas measured by scalp-specific Physician's Global Assessment (ss-PGA) for the scalp

    Time frame: 5 years

  10. Treatment modalities and patient's satisfaction with deucravacitinib therapy measured by the Treatment Satisfaction Questionnaire for Medication (TSQM)-9

    Time frame: 5 years

  11. Treatment modalities and patient's satisfaction with deucravacitinib therapy measured by the persistence of deucravacitinib therapy

    Time from therapy initiation until discontinuation visualized using Kaplan-Meier methods

    Time frame: 5 years

  12. Treatment modalities and patient's satisfaction with deucravacitinib therapy measured by reasons for therapy discontinuation

    Discontinuation of deucravacitinib defined as a treatment interruption of \>90 days with or without resumption of deucravacitinib treatment, with or without start of a follow-up therapy

    Time frame: 5 years

  13. Patient-reported outcomes measured by the Dermatology Life Quality Index (DLQI)

    Time frame: 5 years

  14. Patient-reported outcomes evaluating pruritus measured by the Itch Numeric Rating Scale (NRS)

    Time frame: 5 years

  15. Patient-reported outcomes measured by the Patient Benefit Index standard version (PBI-S)

    Time frame: 5 years
