E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare the efficacy, as measured by ss-PGA 0/1, of deucravacitinib vs placebo at Week 16 in participants with moderate-to-severe scalp plaque psoriasis |
|
E.2.2 | Secondary objectives of the trial |
- To compare the efficacy, as measured by PSSI 90 response, of deucravacitinib vs placebo at Week 16 in participants with moderate-to-severe scalp plaque psoriasis
- To compare the efficacy, as measured by scalp-specific itch Numeric Rating Scale (NRS) score, of deucravacitinib vs placebo at Week 16 in participants with moderate-to-severe scalp plaque psoriasis
Other Secondary - To assess the safety of deucravacitinib vs placebo in participants with moderate-to-severe scalp plaque psoriasis |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
a) Participant must be ≥ 18 years of age inclusive at the time of signing the ICF b) Men and women diagnosed with stable plaque psoriasis with scalp involvement for 6 months or more. Stable psoriasis is defined as no morphology changes or significant flares of disease activity in the opinion of the Investigator c) Deemed by the Investigator to be a candidate for phototherapy or systemic therapy d) ss-PGA ≥ 3; ≥ 20% SSA; PSSI ≥ 12 at Screening visit and Day 1 e) ≥ 3% of BSA involvement at Screening visit and Day 1 f) Evidence of plaque psoriasis in a non-scalp area g) Failed to respond to, or intolerant of ≥ 1 topical therapy for scalp psoriasis
For a complete list of inclusion criteria, please refer to the protocol. |

E.4 | Principal exclusion criteria |
• Other forms of psoriasis • History of recent infection • Prior exposure to deucravacitinib
For a complete list of exclusion criteria, please refer to the protocol. |

E.5 End points |
E.5.1 | Primary end point(s) |
ss-PGA 0/1 response as a proportion of participants with anss-PGA score of 0 (clear) or 1 (almost clear) with at least a 2-point reduction from baseline at Week 16 |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
