A Study to Evaluate Effectiveness and Safety of Deucravacitinib in Participants With Non-Pustular Palmoplantar and Genital Psoriasis

Prior treatment

• Has non-plaque psoriasis (for PP pustulosis, PP pustular psoriasis, isolated pustules on palms or soles with or without erythema outside psoriatic plaques, guttate, pustular, erythrodermic, and drug-induced psoriasis) at screening or Day 1.
  • Other protocol-defined inclusion/exclusion criteria apply.

Other illness

• Target Disease Exceptions

• Men and women diagnosed with stable plaque psoriasis with involvement of the palm(s)and/or sole(s) for at least 6 months or more. Stable psoriasis is defined as no morphology changes or significant flares of disease activity in the opinion of the investigator.
• Moderate-to-severe plaque psoriasis defined as s-PGA score of ≥ 3 on a 5-point scale at both screening visit and Day 1.
• Moderate-to-severe non-pustular PP psoriasis, defined as pp-PGA score of ≥ 3 on a 5-pointscale and pp-PASI ≥ 8 at both screening visit and Day 1.
  • A total maximum of 5 sterile pustules across both palms and soles limited only to psoriatic plaques will be allowed.
• Evidence of typical plaque psoriasis outside palms and soles at both screening visit and Day 1.
• Deemed by the investigator to be a candidate for phototherapy or systemic therapy.
• Failed to respond to, or intolerant of ≥ 1 topical therapy.
• Men and women diagnosed with stable plaque psoriasis with involvement of the genital area for at least 6 months or more. Stable psoriasis is defined as no morphology changes or significant flares of disease activity in the opinion of the investigator.
• Moderate-to-severe plaque psoriasis defined as s-PGA score of ≥ 3 on a 5-point scale at both screening visit and Day 1.
• Moderate-to-severe GenPs, defined as static Physician's Global Assessment of Genitalia (s-PGA-G) score of ≥ 3 on a 6-point scale at both screening visit and Day 1.
• Evidence of typical plaque psoriasis in a non-genital area at both screening visit and Day 1.
• Deemed by the investigator to be a candidate for phototherapy or systemic therapy.
• Failed to respond to, or intolerant of ≥ 1 topical therapy.
