  • Topical Steroids Cannot Be Used Long-Term on a Two-Year-Old’s Face or Skin Folds. For Children That Young With Plaque Psoriasis, There Has Been Almost Nothing Else. Zoryve Cream Just Changed That.

    Topical Steroids Cannot Be Used Long-Term on a Two-Year-Old’s Face or Skin Folds. For Children That Young With Plaque Psoriasis, There Has Been Almost Nothing Else. Zoryve Cream Just Changed That.

    The essentials: On June 29, 2026, the FDA expanded the approval of Zoryve (roflumilast) cream 0.3% (Arcutis Biotherapeutics) to include children aged 2 years and older with plaque psoriasis, including intertriginous areas. The prior lower age limit was 6 years. The new approval makes Zoryve cream 0.3% the first once-daily, steroid-free topical treatment for plaque psoriasis approved down to age 2, and the only topical PDE4 inhibitor approved for plaque psoriasis in children under 6. This is not a new drug. Roflumilast is the active molecule in Zoryve cream 0.3%, a topical phosphodiesterase 4 (PDE4) inhibitor that has been approved for plaque psoriasis in patients 12 and older since July 2022, extended to ages 6 to 11 in October 2023, and now extended to ages 2 to 5. The indication, including application to intertriginous (skin fold) areas, is now continuous from age 2 through adulthood with no restrictions on duration of use. Formulation: Zoryve cream 0.3% is steroid-free, does not contain PEG, propylene glycol, ethanol, or fragrances, and is applied once daily to affected areas. Supplied in a 60 g tube. The clinical basis for the ages 2 to 5 expansion: Phase 2 open-label MUSE study (ARQ-151-216; NCT04746911), 4 weeks, evaluating pharmacokinetics, safety, tolerability, and exploratory efficacy in children aged 2 to 5 years with plaque psoriasis involving at least 2% BSA; and long-term open-label trial (ARQ-151-306; NCT04286607) providing supportive safety, tolerability, and efficacy data through 24 weeks. At week 4 in the MUSE 2-to-5 cohort (n=10): IGA success 90%; PASI-75 90%; Worst Itch NRS success 90% (caregiver-reported). Safety consistent with the established profile in older patients. Systemic absorption detected but within acceptable bounds under maximal-use conditions, consistent with prior adult and adolescent pharmacokinetic observations. AAD designation: strong recommendation for Zoryve cream 0.3% in pediatric atopic dermatitis ages 6 and older in the AAD’s first-ever pediatric atopic dermatitis guidelines (April 2026). National Psoriasis Foundation Seal of Recognition awarded to Zoryve cream 0.3% and Zoryve foam 0.3%, the first FDA-approved prescription brand to receive this honor.

    The first thing most people need to understand about psoriasis in very young children is that it looks and behaves differently from psoriasis in adults, and the places it appears most commonly are precisely the places where standard treatment is most constrained. A two-year-old with plaque psoriasis is not just a smaller version of a forty-year-old with plaque psoriasis. The disease in toddlers and preschool-age children frequently involves the face, including the hairline and ears, and the skin folds: the diaper area, groin, axillae, and neck creases. These are all areas where topical corticosteroids, the standard of care for decades, carry the highest risk of local adverse effects with extended use.

    Topical corticosteroids applied to the face and intertriginous areas of young children can cause skin atrophy, striae, telangiectasia, and with potent or prolonged application, suppression of the hypothalamic-pituitary-adrenal axis. Guidelines do not support their long-term use in these locations. But pediatric plaque psoriasis is a chronic disease. It does not resolve after a four-week course of cream. Families managing it need a treatment that can be applied consistently, anywhere on the body, for as long as the disease requires. For children under six, there has been essentially nothing that meets that description.

    Zoryve cream 0.3% (roflumilast, Arcutis Biotherapeutics) received FDA approval on June 29, 2026, for the treatment of plaque psoriasis in children as young as age 2, making it the first once-daily steroid-free treatment for plaque psoriasis approved in this age group. The approval closes a real prescribing gap rather than an incremental one: the drug is now labeled for use anywhere on the body including intertriginous areas, with no restrictions on duration, from age 2 through adulthood.


    The Pediatric Psoriasis Treatment Gap: Why This Age Range Matters

    Pediatric psoriasis affects approximately 1% of children and accounts for roughly 30% of all psoriasis cases when considered across lifetime onset. Onset in the first five years of life is not uncommon, and early-onset disease is often associated with a chronic relapsing course that extends into adulthood.

    For children under six, the practical treatment options before this approval were:

    Emollients and moisturizers: Appropriate for all pediatric psoriasis as supportive care but not therapeutic in moderate disease.

    Mild topical corticosteroids: Acceptable for short-term use on the body in young children, but guidance against extended use on the face, skin folds, and genital area is consistent across dermatology guidelines. The very areas most commonly affected by psoriasis in toddlers are the areas most restricted for steroid use.

    Topical calcineurin inhibitors (tacrolimus, pimecrolimus): Approved for atopic dermatitis but carry an FDA boxed warning about a theoretical cancer risk that has made many families and clinicians reluctant to use them long-term, despite the fact that current evidence does not substantiate the concern. Not approved for psoriasis.

    Coal tar preparations: Older, generally well-tolerated, but cosmetically challenging and with limited acceptability in daily use on young children.

    Systemic therapy: Not appropriate for most toddlers with mild-to-moderate plaque psoriasis, and options for systemic therapy in children under 6 are even more constrained than for older children.

    The result: families of young children with chronic plaque psoriasis have often cycled through short courses of topical steroids, periods without effective treatment, and repeated conversations with pediatric dermatologists about what to do next. This is the clinical reality that the Zoryve cream 0.3% approval for ages 2 to 5 addresses.

    As Dr. Lisa Swanson, a board-certified pediatric dermatologist at Ada West Dermatology and a clinical trial investigator, noted: “Young children with plaque psoriasis face unique challenges, including disease involvement on sensitive skin, such as the face and skin folds. In clinical studies, Zoryve cream 0.3% demonstrated consistent safety and efficacy in improving the signs and symptoms of plaque psoriasis as seen in adults and adolescents, and was safe and well tolerated in children as young as age 2.”


    What Roflumilast Is: The PDE4 Inhibitor Mechanism in Skin Disease

    Roflumilast is a selective inhibitor of phosphodiesterase type 4 (PDE4), a family of intracellular enzymes responsible for degrading cyclic AMP (cAMP). PDE4 is the dominant phosphodiesterase in immune and inflammatory cells, including T cells, neutrophils, eosinophils, macrophages, and keratinocytes.

    Under normal signaling conditions, cAMP acts as an intracellular second messenger that inhibits pro-inflammatory activity in immune cells. When PDE4 degrades cAMP, this anti-inflammatory brake is released and inflammatory mediators are produced. By inhibiting PDE4, roflumilast prevents cAMP degradation, allowing cAMP to accumulate intracellularly, which suppresses the production of pro-inflammatory cytokines including TNF-alpha, IL-2, IL-4, IL-5, IL-12, IL-13, IL-17, and IL-23. These are precisely the cytokines that drive psoriatic skin inflammation.

    The clinical consequence of this mechanism in psoriasis is anti-inflammatory activity that reduces plaque thickness, erythema, and scaling without the structural effects of corticosteroids on the skin. Roflumilast does not thin the skin, does not cause striae, and does not suppress adrenal function. These properties are what enable its use without restrictions on body site or treatment duration.

    Roflumilast in oral form (Daliresp) has been approved since 2011 for COPD, where it reduces systemic inflammation. The topical formulations used in dermatology are chemically the same molecule but delivered in cream and foam vehicles designed to maximize skin penetration while minimizing systemic absorption.

    The Zoryve cream formulation is notable for what it does not contain alongside the active ingredient: no PEG, no propylene glycol, no ethanol, and no fragrances. These are common irritants and sensitizers that make many topical preparations inappropriate for inflamed or sensitive skin in young children. The absence of these excipients is a meaningful formulation attribute for the ages 2 to 5 population, where skin barrier function may already be compromised by psoriatic inflammation.


    How Zoryve Cream 0.3%’s Approval History Has Expanded: Age by Age

    Understanding this approval requires understanding where Zoryve cream 0.3% stands in the broader Zoryve portfolio and how its age indication has been systematically extended.

    ApprovalDateIndicationAge range
    Original Zoryve cream 0.3%July 29, 2022Plaque psoriasis including intertriginous areasAges 12 and older
    Age expansionOctober 9, 2023Plaque psoriasis including intertriginous areasAges 6 and older (added 6 to 11)
    Zoryve cream 0.15%July 9, 2024Mild-to-moderate atopic dermatitisAges 6 and older
    Zoryve cream 0.05%October 2025Mild-to-moderate atopic dermatitisAges 2 to 5
    This approvalJune 29, 2026Plaque psoriasis including intertriginous areasAges 2 and older (added 2 to 5)

    The Zoryve portfolio now covers plaque psoriasis and atopic dermatitis across overlapping pediatric age ranges with different concentrations tailored to the inflammation depth and pharmacokinetic considerations relevant to each age group. For plaque psoriasis specifically, Zoryve cream 0.3% now covers from age 2 through adulthood in a continuous, unrestricted indication.

    Zoryve foam 0.3%, approved separately for scalp and body plaque psoriasis, is indicated for adults and patients aged 12 and older and has not been extended to younger children in this action.


    The MUSE Study and Supporting Data: What the Evidence Shows

    The FDA approval for ages 2 to 5 is based on two clinical studies specifically conducted in this age group, supported by the larger efficacy database in older patients.

    MUSE study (ARQ-151-216; NCT04746911)

    The MUSE study was a Phase 2, open-label trial evaluating roflumilast cream 0.3% in children aged 2 to 5 years (n=10) with plaque psoriasis involving at least 2% body surface area. This was a maximal usage systemic exposure study, meaning the drug was applied to the maximum amount of affected skin to evaluate pharmacokinetics and confirm that systemic absorption under worst-case conditions remained within acceptable safety limits.

    At 4 weeks:

    EndpointResult (ages 2 to 5, n=10)
    IGA success (clear or almost clear, plus at least 2-grade improvement)90%
    PASI-75 (at least 75% improvement in PASI)90%
    WI-NRS success (at least 4-point reduction in worst itch, caregiver-reported for children under 8)90%

    Source: HCPLive MUSE data summary. June 2026. NCT04746911.

    Evidence of systemic absorption of roflumilast and its active N-oxide metabolite was detected in most participants, consistent with prior Phase 3 pharmacokinetic data in adults and adolescents. The pharmacokinetic profiles were within the acceptable range established by the broader adult and adolescent safety database.

    Long-term open-label study (ARQ-151-306; NCT04286607)

    The long-term study provided supportive safety and efficacy data through up to 24 weeks of treatment in children aged 2 to 5 years. Results showed the safety and efficacy of roflumilast cream 0.3% in patients 2 years and older were generally consistent with those observed in clinical trials involving pediatric patients aged 6 to 11 years, adolescents, and adults.

    Interpreting the small-n MUSE data honestly

    The MUSE cohort for ages 2 to 5 enrolled 10 patients. This is a small sample, and the 90% response rates at 4 weeks should be interpreted in that context: with n=10, each patient accounts for 10 percentage points of any rate. The open-label, single-arm design without a placebo comparator also means the observed rates include the natural course of psoriasis during the observation period alongside the drug effect.

    The FDA’s decision to approve based on this data rests on several established principles for pediatric drug development. The efficacy of roflumilast cream 0.3% has been established in large, well-controlled Phase 3 trials in adults and adolescents (DERMIS-1 and DERMIS-2). The mechanism of action and pharmacokinetics are well-characterized across multiple age groups. The MUSE study’s role was primarily to confirm that systemic exposure in the youngest children does not differ meaningfully from the established safety-relevant exposure range in older patients, and that the clinical response is directionally consistent with what has been observed in the rest of the population. Both were confirmed.

    The single most important limitation to acknowledge: long-term pharmacokinetic surveillance in children aged 2 to 5 with real-world application patterns is not available from the clinical trial program. The MUSE design was built for maximal use conditions over 4 weeks. Whether extended real-world use in this age group produces different systemic exposure patterns will be learned over time in clinical practice.


    The Established Phase 3 Efficacy Base: DERMIS-1 and DERMIS-2

    Because the ages 2 to 5 approval relies on consistency with the broader efficacy database, understanding that broader database is essential context for clinicians and families.

    DERMIS-1 (NCT04211363) and DERMIS-2 (NCT04211389) were the pivotal Phase 3 trials supporting the original roflumilast cream 0.3% approvals. Both were 8-week, randomized, double-blind, vehicle-controlled trials in patients aged 2 years and older (the trials were designed with the full age range in mind, though the youngest age group’s formal approval has come in stages).

    At week 8, significantly more roflumilast-treated than vehicle-treated patients achieved PASI-75 (40.3% versus 6.5%; p less than 0.0001). Using the more sensitive PASI-HD endpoint, which captures finer changes in plaque thickness, erythema, and scaling, 59.9% versus 17.9% achieved the threshold at week 8 (p less than 0.0001).

    Among patients with intertriginous psoriasis, IGA success in the affected intertriginous area was achieved in 73% of roflumilast 0.3%-treated patients versus 29% of vehicle-treated patients. This intertriginous-specific response rate is clinically significant given how commonly this body site is affected in young children with psoriasis.

    These are the efficacy data that anchor the confidence in the younger age group approval: a drug with well-demonstrated efficacy in adults and older children, consistent pharmacokinetic behavior across age groups in the MUSE studies, and directionally consistent response rates in the 2-to-5 cohort.


    Zoryve’s Full Current Indication Coverage After June 2026

    ProductIndicationAge range
    Zoryve cream 0.3%Plaque psoriasis, including intertriginous areasAges 2 and older
    Zoryve foam 0.3%Plaque psoriasis, scalp and bodyAges 12 and older
    Zoryve cream 0.15%Mild-to-moderate atopic dermatitisAges 6 and older
    Zoryve cream 0.05%Mild-to-moderate atopic dermatitisAges 2 to 5

    Zoryve is also approved for seborrheic dermatitis in foam formulation in adults. The portfolio now represents the broadest age coverage of any topical PDE4 inhibitor franchise in the United States.


    Safety: What Prescribers and Caregivers Need to Know

    The safety profile of Zoryve cream 0.3% in the ages 2 to 5 population was consistent with the established profile in older patients and adults. No new safety signals emerged in the MUSE study or the long-term extension study.

    Contraindication: Zoryve cream 0.3% is contraindicated in patients with moderate-to-severe liver impairment (Child-Pugh B or C). This reflects the hepatic metabolism of roflumilast and is standard across all roflumilast formulations.

    Common adverse reactions (occurring in at least 1% of patients in clinical trials of Zoryve cream 0.3% for plaque psoriasis): diarrhea, headache, insomnia, nausea, application site pain, upper respiratory tract infection, and urinary tract infection. These reflect low-level systemic exposure to roflumilast even from a topical formulation, consistent with the known pharmacology of PDE4 inhibition.

    Systemic absorption in young children: Roflumilast is absorbed to a small degree through the skin. In the MUSE study, systemic exposure was detected in most participants aged 2 to 5 under maximal-use conditions. The FDA considered this acceptable based on consistency with adult and adolescent exposure levels. For clinical practice, applying the drug to the minimum area necessary to control disease, rather than liberally to all skin regardless of activity, is appropriate practice in any age group.

    No boxed warning, no restriction on duration, no restriction on body site including face, skin folds, and genitalia. These are the specific label attributes that make roflumilast cream 0.3% suitable as a long-term topical option in young children with psoriasis in locations where corticosteroids cannot be used indefinitely.

    Driving and machinery: Not relevant for the ages 2 to 5 population. The adverse event of headache, nausea, and insomnia noted in clinical trials are worth monitoring; caregivers should report persistent systemic symptoms to the treating dermatologist.


    What This Means for Pediatric Dermatologists and Families

    For pediatric dermatologists

    This approval fills a specific prescribing gap that has been documented in the literature for years: children aged 2 to 5 with moderate plaque psoriasis involving the face and intertriginous areas, where corticosteroids are inappropriate for long-term use, now have an FDA-approved once-daily steroid-free option. The label explicitly covers these body sites, which removes any ambiguity about whether the approval supports use in the locations most relevant to this age group.

    The MUSE data should be interpreted in the context of the broader Phase 3 efficacy database and the established pharmacokinetic consistency across age groups, rather than as a standalone primary efficacy study. The response signals in the 2-to-5 cohort were directionally strong (90% IGA success at 4 weeks), but the n=10 sample size means these numbers carry wide uncertainty bounds.

    The AAD’s strong recommendation for various Zoryve formulations in pediatric atopic dermatitis, combined with this psoriasis indication expansion, makes roflumilast a versatile topical option for pediatric inflammatory skin disease broadly, with age-appropriate concentrations and indications mapped across the full pediatric range.

    For families

    If your child is aged 2 to 5 and has been diagnosed with plaque psoriasis, and particularly if their disease involves the face, diaper area, groin, or other skin folds where you have been told steroid creams cannot be used long-term, Zoryve cream 0.3% is now an FDA-approved option that your child’s pediatric dermatologist can prescribe.

    The cream is applied once daily to affected areas. It does not need to be washed off before bedtime. It can be applied to skin folds. There is no defined treatment duration limit. It is steroid-free and does not contain common skin irritants.

    Because Zoryve cream 0.3% is a specialty prescription product, insurance prior authorization is typically required. Arcutis operates a patient support program, Arc+, that provides insurance and access support for patients prescribed Zoryve. A specialty pharmacy familiar with Arcutis products can help navigate the prior authorization process.

  • Pediatric Psoriasis Has Lacked Good Biologic Options for Younger Children and Smaller Patients. Skyrizi Just Became the First IL-23 Inhibitor Approved Down to Age Six and Under 40 Kilograms.

    The essentials: On June 26, 2026, the FDA expanded the approval of Skyrizi (risankizumab-rzaa, AbbVie) to include two pediatric indications: moderate-to-severe plaque psoriasis in children aged 6 years and older who are candidates for systemic therapy or phototherapy, and active psoriatic arthritis in children aged 6 years and older. Both approvals cover pediatric patients regardless of body weight. A new 55 mg pre-filled syringe has been simultaneously approved to support weight-based dosing for patients weighing less than 40 kg. The existing 150 mg pre-filled syringe and pen remain approved for patients weighing 40 kg or more. This makes Skyrizi the first and only IL-23 inhibitor approved in the United States for pediatric patients aged 6 years and older who weigh less than 40 kg with plaque psoriasis or psoriatic arthritis. The European Commission approved risankizumab for pediatric plaque psoriasis in the same age group on June 23, 2026, three days before the U.S. action. The clinical basis for the plaque psoriasis approval: Phase 3 OptIMMize-1 (NCT04435600) and OptIMMize-2 (NCT04862286). Adolescents aged 12 to younger than 18 years (n=82, randomized 2:1 risankizumab versus ustekinumab): at week 16, PASI75 achieved in 85.2% (risankizumab) versus 85.7% (ustekinumab); PASI90 64.8% versus 60.7%; PASI100 40.7% versus 17.9%; sPGA0/1 79.6% versus 75.0%. Responses maintained or improved at week 52; sPGA0/1 achieved in approximately 95% of risankizumab responders who continued to week 52. Children aged 6 to younger than 12 years (n=30, open-label, single-arm): at week 16, PASI75 86.7%; PASI90 76.7%; PASI100 43.3%; sPGA0/1 90.0%. Responses maintained or improved through week 52. The psoriatic arthritis approval was supported by the OptIMMize program data plus population pharmacokinetic modeling and simulation extrapolated from well-controlled adult PsA studies. No dedicated randomized pediatric PsA efficacy trial was conducted. Safety profile in pediatric patients was consistent with the established adult safety profile. Skyrizi was originally approved in April 2019 for adults with moderate-to-severe plaque psoriasis and subsequently approved for adults with active psoriatic arthritis (2022), Crohn’s disease (2022), and ulcerative colitis (2024).

    Psoriasis in children is not the same clinical experience as psoriasis in adults. The visible, chronic, and often unpredictable nature of the disease shapes childhood in ways that extend well beyond the skin. School-age children with moderate-to-severe plaque psoriasis deal with itching, pain, and lesions during the years when peer relationships form and self-image develops. Adolescents navigate a disease that can appear on exposed skin just as social self-consciousness peaks. Parents manage the daily treatment burden alongside their own anxiety about long-term treatment options for a child whose body and immune system are still developing.

    The treatment toolkit for moderate-to-severe pediatric psoriasis has been narrower than most clinicians and families would like. Methotrexate, cyclosporine, and acitretin are systemic options that carry meaningful toxicity concerns in children. Etanercept, a TNF inhibitor, has been approved for pediatric psoriasis for many years. Secukinumab and ixekizumab, IL-17 inhibitors, expanded the pediatric biologic options. But the IL-23 inhibitor class, which in adults has produced some of the most durable and complete skin clearance rates seen in dermatology, has until now been unavailable to children.

    Skyrizi (risankizumab-rzaa, AbbVie) changed that on June 26, 2026. The approval covers children as young as six years old, extends to patients weighing less than 40 kg through a new weight-based formulation, and includes both plaque psoriasis and psoriatic arthritis. It is the first time any IL-23 inhibitor has received FDA approval for pediatric psoriatic disease, and it is supported by Phase 3 data showing complete skin clearance in more than 40% of treated children at 16 weeks, with responses maintained through a year of treatment.


    What Pediatric Psoriasis and Psoriatic Arthritis Are

    Plaque psoriasis in children

    Plaque psoriasis is a chronic immune-mediated skin disease characterized by well-demarcated, raised, erythematous plaques covered by silvery-white scale. It results from dysregulated immune activation that accelerates the normal skin cell lifecycle from 28 to 30 days down to 3 to 5 days, causing immature keratinocytes to accumulate on the skin surface in the characteristic plaques. The scalp, elbows, knees, and trunk are the most commonly affected areas, though involvement can occur anywhere on the body including the face, nails, and flexural areas.

    Pediatric psoriasis affects approximately 1% of children globally and accounts for roughly 30% of all psoriasis cases when considered across lifetime onset. Onset most commonly occurs in the first two decades of life, with two peaks: one in early childhood and one in adolescence. The disease presentation in children can differ from adults, with facial involvement, scalp disease, and guttate morphology (small, drop-like lesions often triggered by streptococcal infection) being more common in younger patients.

    Moderate-to-severe disease, the population covered by this approval, is defined by a Psoriasis Area and Severity Index (PASI) above 10 or body surface area involvement above 10%, or disease affecting critical areas including the face, palms, soles, or genitalia regardless of BSA. Patients with moderate-to-severe disease are candidates for systemic therapy or phototherapy, the threshold specified in the approval.

    The psychosocial burden of pediatric psoriasis is substantial and often underappreciated in clinical settings. Studies consistently show that children with psoriasis have higher rates of depression, anxiety, social withdrawal, and reduced health-related quality of life compared to peers without skin disease. Adolescents are particularly affected. These psychological consequences are among the reasons that achieving complete or near-complete skin clearance, rather than merely reducing plaque severity, has become the goal of modern biologic therapy.

    Psoriatic arthritis in children

    Psoriatic arthritis in children, sometimes referred to as juvenile psoriatic arthritis within the broader category of juvenile idiopathic arthritis, involves inflammation of the joints that occurs in the setting of psoriatic disease. It presents with swollen, tender joints, morning stiffness, and in some children with characteristic features including dactylitis (sausage-shaped swelling of fingers or toes) and enthesitis (inflammation at tendon or ligament insertion sites). Without adequate treatment, pediatric psoriatic arthritis can cause permanent joint damage and growth abnormalities.

    The psoriatic arthritis indication in this approval is meaningful because children with psoriasis are at elevated risk of developing arthritis, and early effective treatment of both the skin and joint manifestations can prevent structural damage. The evidentiary basis for the PsA approval in children rests on population pharmacokinetic modeling and simulation from adult PsA trials, along with the psoriasis data from OptIMMize, rather than a dedicated randomized pediatric PsA efficacy trial. This extrapolation approach is acceptable under FDA pediatric development frameworks when the disease mechanism and drug pharmacology are well-characterized in adults and PK data support comparable drug exposure in children. However, it is a meaningful limitation that clinicians and families should understand during shared decision-making, particularly for younger children.


    How Risankizumab Works: The IL-23 Mechanism

    Risankizumab is a humanized IgG1 monoclonal antibody that selectively targets interleukin-23 (IL-23), specifically the p19 subunit of the IL-23 cytokine. IL-23 is a key regulatory cytokine produced by antigen-presenting cells (dendritic cells and macrophages) in response to immune stimulation. Its primary function is to promote the differentiation, expansion, and survival of Th17 cells, the T helper cell population that drives much of the inflammatory activity in psoriatic disease.

    By blocking IL-23 at its p19 subunit, risankizumab interrupts this cascade before it begins. With less IL-23 available, Th17 cell populations cannot expand normally. As a result, the downstream cytokines that drive psoriatic inflammation, principally IL-17A, IL-17F, and IL-22, are produced in lower quantities. The result is a reduction in keratinocyte hyperproliferation, dermal inflammation, and the immune-mediated joint damage that characterizes psoriatic arthritis.

    The IL-23 p19 targeting approach distinguishes risankizumab and the other IL-23 inhibitors (guselkumab, tildrakizumab) from IL-12/23 dual inhibitors like ustekinumab, which block the shared p40 subunit of both IL-12 and IL-23. By specifically targeting IL-23 and sparing IL-12, risankizumab does not interfere with IL-12-dependent immune responses that are important for host defense against certain infections, a theoretical advantage over dual inhibition that is reflected in the clinical safety profile.

    The practical consequence of this mechanism for patients is that risankizumab produces deep and durable skin clearance by addressing the upstream cytokine driver of psoriatic disease rather than its downstream effects. In adult trials, risankizumab has produced PASI90 and PASI100 rates that are among the highest reported for any psoriasis biologic, and these effects are sustained over years of treatment.


    The OptIMMize Program: What the Pediatric Data Shows

    The FDA approval for pediatric plaque psoriasis rests on data from Phase 3 OptIMMize-1 (NCT04435600) and its open-label extension OptIMMize-2 (NCT04862286). The program included four components: two lead-in pharmacokinetic cohorts that established age- and weight-appropriate dosing, a randomized active-controlled cohort in adolescents aged 12 to younger than 18, and a single-arm open-label cohort in children aged 6 to younger than 12.

    Adolescents aged 12 to younger than 18 years: randomized cohort

    In the randomized cohort, 82 adolescents were randomized 2:1 to risankizumab (n=54) or ustekinumab (n=28) for 16 weeks. Ustekinumab was chosen as the active comparator because it was, at the time the trial was designed, one of the few biologics with established pediatric psoriasis data and approval. Both drugs were dosed according to weight-based protocols consistent with their respective approved adult dosing frameworks.

    Endpoint at week 16Risankizumab (n=54)Ustekinumab (n=28)
    PASI75 (at least 75% improvement in PASI)85.2%85.7%
    PASI90 (at least 90% improvement in PASI)64.8%60.7%
    PASI100 (complete skin clearance)40.7%17.9%
    sPGA0/1 (clear or almost clear)79.6%75.0%
    sPGA0/1 with at least 2-grade improvement68.5%67.9%

    Source: Magnolo N, Lee LW, Reich A et al. Efficacy and safety of risankizumab in pediatric patients with psoriasis: results from the OptIMMize-1 phase 3 study. J Invest Dermatol. 2026;146(3):S19. NCT04435600.

    The PASI75 results were comparable between risankizumab and ustekinumab at week 16, meaning both drugs achieved substantial disease control at a similar rate in this population. The more clinically meaningful differentiator was the PASI100 rate: complete skin clearance in 40.7% of risankizumab-treated adolescents versus 17.9% of ustekinumab-treated adolescents. In practical terms, more than twice as many adolescents treated with risankizumab achieved completely clear skin at 16 weeks compared to those on ustekinumab.

    Durability through week 52 was maintained and in many cases improved. Among adolescents who responded to risankizumab and continued treatment through week 52, sPGA0/1 (clear or almost clear skin) was achieved in approximately 95% of patients. This long-term durability is consistent with what has been observed in adult risankizumab trials, where sustained responses without tachyphylaxis have been a characteristic feature of the drug.

    Children aged 6 to younger than 12 years: open-label cohort

    The younger cohort (n=30) was evaluated in a single-arm, open-label design, which is appropriate for this age group given the practical and ethical challenges of conducting blinded, placebo-controlled trials in young children with moderate-to-severe skin disease. These children received the 55 mg dose (for those under 40 kg) or the standard adult dose (for those at or above 40 kg) and were evaluated at week 16 and through week 52.

    Endpoint at week 16Risankizumab (n=30)
    PASI7586.7%
    PASI9076.7%
    PASI100 (complete skin clearance)43.3%
    sPGA0/1 (clear or almost clear)90.0%
    sPGA0/1 with at least 2-grade improvement83.3%

    Source: OptIMMize-1/2 open-label cohort, ages 6 to younger than 12. NCT04435600/NCT04862286.

    These response rates are high across all measures. A 90% rate of clear or almost clear skin at 16 weeks, alongside a 43.3% rate of complete skin clearance, represents an efficacy signal in children aged 6 to 11 that is consistent with and in some measures exceeds what has been observed in adult trials with risankizumab. Responses in this younger cohort were maintained or improved through week 52, confirming sustained disease control over a year of treatment.

    An important interpretive note: the open-label, single-arm design of the younger cohort means there is no placebo or active comparator for this group’s results. Response rates in open-label trials are generally higher than in blinded, placebo-controlled trials because of patient and investigator expectancy effects and the known PASI improvement that occurs in some patients over time even without active treatment (regression to the mean). This is a recognized limitation of pediatric trial design in diseases where withholding treatment from children with moderate-to-severe psoriasis for the duration of a placebo-controlled study raises ethical concerns. The FDA’s approval for this age group reflects a judgmental weighing of the unmet medical need, the consistency of the results with the mechanistic and adult evidence base, and the favorable safety profile.


    The New 55 mg Formulation: Why Weight-Based Dosing Matters for Children

    The simultaneous approval of a 55 mg pre-filled syringe specifically for patients weighing less than 40 kg is a clinically important element of this approval that could easily be overlooked in headlines focused on the age extension.

    Children under 40 kg receiving the standard adult 150 mg dose would receive a substantially higher mg/kg dose than intended, with potential implications for both safety and long-term tolerability. The 55 mg dose was developed through the pharmacokinetic lead-in cohorts of OptIMMize, which characterized risankizumab exposure across the pediatric weight and age range and identified the dose that achieves drug exposure comparable to the adult 150 mg dose on a per-kilogram basis.

    This weight-based dosing approach is what allows the approval to extend meaningfully to children aged 6 to 11, many of whom will weigh less than 40 kg. Without a lower-dose formulation, the approval would carry a practical limitation that undermined its clinical utility in younger and smaller children. With it, clinicians have a dosing framework that is pharmacokinetically grounded rather than extrapolated downward from adult dosing.

    Patient weightRisankizumab doseFormulation
    Less than 40 kg55 mg subcutaneous injectionNew 55 mg pre-filled syringe
    40 kg or more150 mg subcutaneous injectionExisting 150 mg pre-filled syringe or pen

    Dosing schedule mirrors the adult schedule: subcutaneous injection at weeks 0 and 4, then every 12 weeks for maintenance. This 12-weekly maintenance schedule is one of the most infrequent in the biologic psoriasis class and is a meaningful practical advantage for families managing a child’s long-term treatment. Fewer injections per year reduces the physical and psychological burden on both the child and the caregivers who administer the medication.


    The Psoriatic Arthritis Approval: What the Evidence Does and Does Not Cover

    The psoriatic arthritis approval for children aged 6 and older is supported by two distinct evidentiary streams: the OptIMMize psoriasis data (establishing the drug’s safety and efficacy in the same age group for the related psoriatic condition) and population pharmacokinetic modeling and simulation extrapolated from well-controlled adult PsA trials, including the KEEPsAKE-1 and KEEPsAKE-2 trials that supported the 2022 adult PsA approval.

    The modeling demonstrates that the weight-based risankizumab dosing approved for pediatric psoriasis achieves drug exposures in children similar to those produced by the 150 mg adult dose that was shown to be effective in adult PsA trials. The FDA considered this extrapolation appropriate given the shared pathophysiology between adult and pediatric psoriatic arthritis, the well-established adult efficacy database, and the pharmacokinetic consistency across weight groups.

    What the approval does not include is a dedicated randomized, controlled efficacy trial specifically in children with psoriatic arthritis. This is the most important limitation for clinicians managing pediatric PsA patients considering risankizumab. The drug is approved and the pharmacokinetic rationale is sound, but clinicians and families should understand that the PsA efficacy evidence is extrapolated rather than directly demonstrated in this age group. For children with active joint disease alongside psoriasis, this distinction should be part of the treatment discussion.


    Safety: Consistent with the Established Adult Profile

    The safety profile observed in pediatric plaque psoriasis patients treated with Skyrizi was consistent with the established safety profile in adult patients with plaque psoriasis. This is a reassuring finding given that the IL-23 inhibitor class has accumulated a substantial real-world safety dataset across several years of adult use since risankizumab’s original 2019 approval. Patient Care Online

    The key safety considerations from the adult label and their pediatric relevance:

    Serious infections: IL-23 inhibition reduces the Th17-mediated immune response, which plays a role in mucosal defense against certain fungal pathogens including Candida species. Fungal skin infections are among the more common adverse events reported with risankizumab. Serious infections including those requiring hospitalization have been reported in adults, though at low absolute rates. Clinicians treating children should assess for active infection before initiating and monitor for infection signs during treatment.

    Prior to initiating, tuberculosis testing is required. Risankizumab has not been studied in patients with active TB, and the prescribing information requires evaluation for latent TB before treatment. Patients with latent TB should be treated with standard anti-tuberculosis therapy before starting risankizumab.

    Hypersensitivity reactions: Serious hypersensitivity reactions, including anaphylaxis, have been reported. Patients and caregivers should be educated about signs of hypersensitivity and instructed to seek immediate medical attention if they occur.

    Live vaccines: Do not administer live vaccines during risankizumab treatment. This is particularly important in the pediatric setting, where the standard childhood immunization schedule includes live vaccines. The timing of immunizations should be discussed with the prescribing physician before initiating risankizumab. All required vaccinations should be completed before starting treatment wherever possible.

    Common adverse reactions reported in the pediatric trial, consistent with the adult profile, include upper respiratory tract infections, headache, fatigue, injection site reactions, and fungal skin infections.

    Inflammatory bowel disease: In adult trials, rare cases of new or worsening inflammatory bowel disease have been reported with IL-17 inhibitors. While the IBD signal with IL-23 inhibitors is less pronounced and risankizumab is actually approved for Crohn’s disease and ulcerative colitis in adults, clinicians should monitor for GI symptoms in all patients.

    What This Means for Pediatric Dermatologists, Rheumatologists, and Families

    For clinicians

    This approval gives pediatric dermatologists and rheumatologists their first IL-23 inhibitor option for children, the drug class that has produced the most durable complete clearance rates in adult psoriasis. For adolescents aged 12 and older who have failed or are intolerant to methotrexate or a TNF inhibitor and are candidates for an IL-23 inhibitor, the OptIMMize data now provides direct randomized evidence in their age group comparing risankizumab favorably to ustekinumab, particularly on the metric of complete skin clearance.

    For children aged 6 to 11, the open-label data and the weight-based dosing framework are now available, though the single-arm design means clinicians should interpret the efficacy data with appropriate awareness of its limitations.

    For the psoriatic arthritis indication in children: the extrapolation-based approval is appropriate for use in clinical practice but should be accompanied by discussion with the family of the evidentiary basis, so that treatment expectations and monitoring plans reflect what is and is not directly demonstrated in children.

    The 12-weekly maintenance dosing schedule is a meaningful practical advantage for pediatric patients. Fewer clinic visits and fewer injections per year reduce treatment burden on children and families and may improve long-term adherence.

    For families

    If your child has been diagnosed with moderate-to-severe plaque psoriasis or psoriatic arthritis and is at least 6 years old, risankizumab is now an FDA-approved option that your child’s pediatric dermatologist or rheumatologist can prescribe. The drug is given as a subcutaneous injection (under the skin, typically in the thigh or abdomen) at weeks 0 and 4, and then every 12 weeks. For children under 40 kg, the new 55 mg dose is specifically designed for their weight range.

    Because Skyrizi is a specialty biologic medication, insurance coverage and prior authorization requirements vary by plan. AbbVie operates a patient support program called myAbbVie Assist for eligible patients who need help with access or cost. A specialty pharmacy familiar with AbbVie biologics can help navigate the prior authorization process and assist with co-pay or patient assistance programs.

    Before starting risankizumab, your child’s doctor will need to: rule out active or latent tuberculosis, review your child’s current vaccination status and complete any needed live vaccines before treatment begins, and review any current or planned medications including other immunosuppressants.

  • The First Oral IL-23 Receptor Blocker for Psoriasis Is FDA-Approved. Here Is What the ICONIC Trial Data Actually Shows.

    The First Oral IL-23 Receptor Blocker for Psoriasis Is FDA-Approved. Here Is What the ICONIC Trial Data Actually Shows.

    The essentials: On March 18, 2026, the FDA approved ICOTYDE (icotrokinra, Johnson & Johnson) for the treatment of moderate to severe plaque psoriasis in adults and adolescents aged 12 years and older weighing at least 40 kg who are candidates for systemic therapy or phototherapy. What makes it mechanistically distinctive: icotrokinra is the first oral peptide that directly blocks the IL-23 receptor, not the IL-23 ligand. All currently approved IL-23-targeting biologics (guselkumab, risankizumab, tildrakizumab) are monoclonal antibodies targeting the IL-23 cytokine itself. Icotrokinra works at the receptor level, introducing a distinct pharmacological approach in an established mechanism. How it is taken: one 200 mg tablet once daily, taken with water upon waking, at least 30 minutes before eating. May be dispersed in water for patients who have difficulty swallowing tablets. Who it is approved for: adults and adolescents aged 12 and older weighing at least 40 kg who are candidates for systemic therapy or phototherapy. The clinical basis: the Phase 3 ICONIC clinical development program across five randomized controlled trials enrolling more than 2,500 patients. Key efficacy numbers at week 16 across trials: IGA 0/1 (clear or almost clear skin) approximately 65 to 70%; PASI 90 approximately 50 to 57%. In head-to-head comparisons, icotrokinra showed superiority to deucravacitinib (Sotyktu) on both primary endpoints. At 52 weeks, complete skin clearance (PASI 100) rates increased to 48 to 49% in two pivotal studies.

    Plaque psoriasis is among the most common immune-mediated skin conditions in the world, affecting more than 125 million people globally. It is not primarily a cosmetic problem. The chronic inflammation that drives the characteristic plaques, scaling, and itch also carries systemic consequences: psoriatic arthritis develops in up to 30% of patients, and individuals with moderate to severe disease have elevated cardiovascular risk, increased rates of depression and anxiety, and substantially reduced quality of life.

    The treatment landscape for moderate to severe plaque psoriasis transformed with the arrival of biologics targeting the IL-17 and IL-23 pathways in the 2010s and 2020s. These injectable therapies produce very high rates of skin clearance but require subcutaneous or intravenous administration, carrying an injection burden that affects adherence for some patients. The oral options in this space have been limited: apremilast (Otezla) is a PDE4 inhibitor with more modest efficacy than IL-17 or IL-23 biologics, and deucravacitinib (Sotyktu) targets TYK2 and has shown meaningful but not biologic-comparable clearance rates.

    ICOTYDE (icotrokinra), approved March 18, 2026, enters this landscape as the first oral therapy targeting the IL-23 receptor directly. The efficacy data from the ICONIC program puts it in a different category from prior oral options and, on some measures, in range of biologic-level responses, in a once-daily pill.


    What Icotrokinra Is and How It Works

    IL-23 (interleukin-23) is a cytokine that plays a central role in the inflammatory cascade driving plaque psoriasis. It activates and sustains Th17 cells, the immune cell population that produces IL-17, the downstream cytokine directly responsible for much of the skin inflammation in psoriasis. Blocking IL-23 at any point in this pathway reduces Th17 activation and downstream inflammation.

    Existing IL-23-targeting biologics work by binding to the p19 subunit of the IL-23 cytokine itself, preventing it from activating its receptor. Icotrokinra takes a different approach: it is an oral peptide that binds directly to the IL-23 receptor (IL-23R) on the surface of immune cells, blocking the receptor from receiving the IL-23 signal regardless of how much IL-23 is present. This is mechanistically analogous to blocking the lock rather than confiscating the key.

    The ability to deliver this level of receptor-targeted precision in an oral small molecule format is what makes icotrokinra mechanistically distinctive. It is not a large protein antibody requiring injection. It is a peptide that survives oral ingestion and reaches the target receptor after absorption from the gastrointestinal tract. The pharmacological challenge of engineering peptides that can do this reliably is substantial, which is why icotrokinra is the first of its kind to reach approval.

    How icotrokinra compares to other oral psoriasis treatments Apremilast (Otezla) is an oral PDE4 inhibitor that broadly dampens inflammatory signaling. It produces IGA 0/1 rates of approximately 20 to 30% at 16 weeks and PASI 75 rates of approximately 40% in pivotal trials. It is generally considered a step below biologics in efficacy for moderate to severe disease. Deucravacitinib (Sotyktu) is an oral TYK2 inhibitor that selectively suppresses IL-23 and IL-12 signaling. In its pivotal POETYK PSO-1 and PSO-2 trials, it produced IGA 0/1 rates of 53 to 58% and PASI 75 rates of 58 to 65% at week 24, positioning it meaningfully above apremilast. Icotrokinra produced IGA 0/1 rates of 65 to 70% and PASI 90 rates of 50 to 57% at week 16 across its pivotal trials, with head-to-head superiority demonstrated directly against deucravacitinib in ICONIC-ADVANCE 1 and 2. No head-to-head trial comparing icotrokinra to IL-17 or IL-23 biologics has been completed. Where icotrokinra fits in the treatment hierarchy will be determined by payer formularies, prescriber experience, and individual patient considerations including injection hesitancy, comorbidities, and treatment history.

    The ICONIC Clinical Development Program: What the Data Shows

    The FDA approval is based on five Phase 3 randomized controlled trials collectively enrolling more than 2,500 patients, designated the ICONIC program. The co-primary endpoints across studies were the proportion of patients achieving IGA 0/1 (clear or almost clear skin) with at least a 2-grade improvement, and PASI 90 (at least 90% improvement in psoriasis severity from baseline), both at week 16.

    ICONIC-ADVANCE 1 and 2: the pivotal approval studies with active comparator

    The two pivotal trials supporting the approval are ICONIC-ADVANCE 1 (NCT06143878) and ICONIC-ADVANCE 2 (NCT06220604), published simultaneously in The Lancet in September 2025. These trials were randomized, double-blind, placebo-controlled and active-comparator-controlled, comparing icotrokinra (200 mg once daily) to both placebo and deucravacitinib (6 mg once daily) in adults with moderate to severe plaque psoriasis.

    Endpoint at Week 16IcotrokinraPlaceboDeucravacitinib
    IGA 0/1 (ADVANCE 1)68% (213/311)11% (17/156)49%
    IGA 0/1 (ADVANCE 2)70% (227/322)9% (7/82)49%

    PASI 100 complete clearance (ADVANCE 2, Week 16)~33%Less than 1%~16%

    Source: Gold et al. The Lancet. 2025. doi:10.1016/S0140-6736(25)01576-4.

    Both coprimary endpoints and all key secondary endpoints were met in each study. Icotrokinra demonstrated statistically significant superiority over deucravacitinib on both IGA 0/1 and PASI 90 at week 16, with treatment differences of approximately 19 to 20 percentage points on IGA 0/1 and approximately 18 to 19 percentage points on PASI 90 versus deucravacitinib. This head-to-head superiority over the most recently approved oral systemic therapy is the most clinically significant efficacy finding in the dataset.

    ICONIC-LEAD: adolescent and adult data

    ICONIC-LEAD (NCT06095115) enrolled 684 participants (456 icotrokinra, 228 placebo) in a 2:1 randomization. This study evaluated both adults and adolescents and provides the specific data supporting the pediatric indication. At week 16, 65% of icotrokinra-treated patients achieved IGA 0/1 versus 8% with placebo (difference 56%; 95% CI 50 to 62%), and 50% achieved PASI 90 versus 4% with placebo (difference 45%; 95% CI 40 to 50%). By week 24, these rates improved to 74% IGA 0/1 and 65% PASI 90.

    ICONIC-TOTAL: high-impact sites

    ICONIC-TOTAL (NCT06095102) specifically enrolled patients with plaque psoriasis affecting high-impact and difficult-to-treat areas including scalp, genitals, and hands/feet. At 52 weeks, 72% of patients with scalp psoriasis achieved scalp-specific IGA 0/1 clearance. Genital and hand/foot clearance rates were similarly high. These difficult-to-treat locations are often where patients report the greatest impact on quality of life and where many existing systemic therapies show lower effectiveness than in non-special site disease.

    52-week durability data

    One-year data from ICONIC-ADVANCE 1, ICONIC-ADVANCE 2, and ICONIC-LEAD, presented at the 2026 American Academy of Dermatology Annual Meeting in March 2026, showed that response rates continued to improve beyond week 16. PASI 100 (completely clear skin) rates increased from 33 to 41% at week 24 to 48 to 49% at week 52 across the two ADVANCE studies. No new safety signals were identified through 52 weeks of treatment.


    Safety Profile

    Across the ICONIC clinical program, icotrokinra demonstrated what the FDA and independent reviewers characterized as a placebo-like safety profile at week 16, with adverse event rates within 1.1 percentage points of placebo. No new safety signals emerged through 52 weeks of follow-up.

    Common adverse events reported in trials:

    • Headache
    • Nausea
    • Cough
    • Mild fungal infections (predominantly oral candidiasis)
    • Upper respiratory tract infection
    • Fatigue

    Key safety considerations from the prescribing information:

    Tuberculosis screening is required before initiating icotrokinra, consistent with other immunomodulating therapies. Live vaccines should not be administered during treatment. Providers should monitor for signs and symptoms of infection throughout the treatment course.

    The absence of the elevated cardiovascular risk signals observed with some JAK inhibitors, and the absence of the hepatic or hematologic monitoring requirements associated with older systemic therapies like methotrexate, are practical clinical advantages in a patient population that often has cardiovascular comorbidities.


    Dosing and Administration

    • Dose: 200 mg once daily
    • Timing: Upon waking, at least 30 minutes before eating
    • Method: One tablet swallowed with water. For patients who have difficulty swallowing tablets, the tablet may be dispersed in at least 120 mL of water; administration should be completed within 15 minutes of dispersion
    • Who is eligible: Adults and adolescents aged 12 years and older weighing at least 40 kg who are candidates for systemic therapy or phototherapy

    Where Icotrokinra Fits in Psoriasis Treatment

    Current treatment guidelines from the American Academy of Dermatology recommend a stepwise approach. Topical therapies are typically first-line for mild disease. Systemic therapy becomes appropriate when topical treatments fail or disease is classified as moderate to severe.

    For systemic therapy, the options now include:

    • Conventional systemic agents: methotrexate, cyclosporine, acitretin. Effective but carry significant monitoring burdens and toxicity profiles
    • Apremilast (Otezla): oral PDE4 inhibitor. Modest efficacy, generally better tolerated than conventional systemic agents
    • Deucravacitinib (Sotyktu): oral TYK2 inhibitor. More effective than apremilast, now demonstrated to be less effective than icotrokinra on primary endpoints
    • Biologic therapies targeting IL-17 or IL-23: highest efficacy class but require injection (ixekizumab, secukinumab, guselkumab, risankizumab, bimekizumab, others)
    • Icotrokinra (ICOTYDE): oral IL-23R peptide. Efficacy on primary endpoints exceeds prior oral options and approaches biologic-level response rates in some analyses

    Icotrokinra’s approval creates a new clinical decision point for prescribers who have patients with moderate to severe disease who prefer or require oral treatment but have not achieved adequate responses on apremilast or deucravacitinib, or who want to avoid injectable biologics.

    Whether icotrokinra will move earlier in the treatment sequence, potentially as first-line systemic therapy, will depend on payer formulary decisions, prescriber adoption patterns, and the results of the ongoing ICONIC-ASCEND trial (NCT06934226), which compares icotrokinra to ustekinumab (an IL-12/23 biologic) and will provide the first direct head-to-head data versus an injectable biologic.


    For Patients

    If you have moderate to severe plaque psoriasis and are currently on a systemic therapy that is not achieving adequate control, or if you have been reluctant to try injectable biologics, icotrokinra adds a clinically meaningful new oral option to the conversation you can have with your dermatologist.

    It is not a replacement for injectable biologics in patients who are doing well on those regimens. It is an alternative for patients for whom oral treatment is preferable, for whom prior oral therapies were insufficient, or who are appropriate candidates for first-line systemic therapy.

    Patient support is available through Johnson & Johnson’s ICOTYDE withMe program, which provides cost assistance options and educational resources. Information on eligibility and enrollment is available at icotyde.com.

    The National Psoriasis Foundation maintains current information on all approved psoriasis treatments, including patient perspectives, treatment decision support tools, and a healthcare provider directory for finding dermatologists with psoriasis expertise. The American Academy of Dermatology’s “Find a Dermatologist” tool is a reliable starting point for patients seeking specialist care.
