HORSHAM, PENNSYLVANIA, August 1, 2022 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced that the U.S. Food and Drug Administration (FDA) has approved STELARA^® (ustekinumab) for the treatment of pediatric patients six years of age and older with active psoriatic arthritis (PsA). This rare disease that resembles adult PsA affects five to eight percent of children and adolescents with chronic inflammatory arthritis.*^1-7 Two of the four indications for STELARA now include pediatric patients, further expanding its treatment profile since the first approval in 2009 for adults living with moderate to severe plaque psoriasis (PsO).

STELARA is a fully human monoclonal antibody that selectively inhibits both interleukin (IL)-12 and IL-23, two cytokines thought to play an important role in tempering the overactive inflammatory response in several autoimmune diseases. STELARA is administered as a subcutaneous injection dosed four times per year after two starter doses for the treatment of pediatric patients six years of age and older with active PsA.

“We know active pediatric psoriatic arthritis is a challenging inflammatory disease given its rarity and that symptoms, such as swollen joints and skin lesions, can vary significantly in presentation and severity,” said Terence Rooney, M.D., Ph.D., Vice President, Rheumatology and Maternal Fetal Disease Area, Janssen Research & Development, LLC. “With this pediatric approval of STELARA, we’re pleased to help address the unmet needs of these young patients and provide physicians with a much-needed treatment option that has an established track record of safety and efficacy.”

The FDA’s approval was based on pharmacokinetic (PK) data and extrapolation of the established efficacy and existing safety profile of STELARA in multiple Phase 3 studies in adult and pediatric patients with moderate to severe plaque PsO (PSTELLAR, CADMUS, and CADMUS Jr) and adult patients with active PsA (PSUMMIT I and II). With the limited availability of pediatric PsA patients for inclusion in clinical trials, researchers utilized an extrapolation approach based on previous PK, efficacy and safety observations from a closely adjacent population of pediatric patients with moderate to severe plaque PsO who also had active PsA, as well as adult patients with moderate to severe plaque PsO or active PsA. An analysis of the data demonstrated that PK exposure of STELARA in these pediatric PsO patients with active PsA was consistent with that of Phase 3 clinical trials of STELARA in pediatric PsO patients without active PsA, as well as with adult patients with moderate to severe plaque PsO or adult patients with active PsA, while data on common efficacy endpoints were similar in these pediatric PsO patients with active PsA.

“The approval of STELARA for use in children six years of age and older with active psoriatic arthritis, which follows the 2020 approval for moderate to severe plaque psoriasis in this population, is complemented by more than 12 years of clinical trial and real-world evidence across all approved indications demonstrating the safety and efficacy of this biologic therapy,” said Jennifer Davidson, DO, Vice President of Immunology Medical Affairs, Janssen Scientific Affairs, LLC. “As a global leader in immunology, Janssen is dedicated to reducing the burden of chronic autoimmune diseases, and this additional approval for STELARA builds on our legacy of bringing important treatment options to younger patients.”

About Active Psoriatic Arthritis in Pediatric Patients
Active psoriatic arthritis (PsA) in pediatric patients, a rare disease that resembles adult PsA, affects five to eight percent of children and adolescents with chronic inflammatory arthritis.*^1-7 Symptoms of active pediatric PsA can vary significantly in presentation and severity from patient to patient, but often include joint inflammation and skin lesions.⁸ PsA can be a challenging disease to treat – especially in younger populations – reinforcing the need for additional treatment options.

About PSTELLAR
PSTELLAR, a Phase 3b, randomized, double-blind, active-controlled, multicenter study assessed the effect of extending maintenance dosing intervals beyond 12 weeks on the clinical efficacy and safety of STELARA in patients with moderate to severe plaque psoriasis. Adults with moderate to severe plaque psoriasis received STELARA at weeks 0, 4 and 16 during open-label treatment. Patients achieving a week-28 Physician's Global Assessment (PGA) score of cleared/minimal (PGA = 0/1) were randomized 1:4 to group 1 [approved every 12 weeks (q12 wk) maintenance] or group 2 (q12-24 wk; response-based dosing determined by time to loss of PGA = 0/1). Key endpoints included the number of visits with PGA = 0/1 (primary end point) and ≥ 75 percent improvement in Psoriasis Area and Severity Index (PASI 75) between weeks 88 and 112, and PGA/PASI responses between weeks 28 and 112.

About CADMUS
CADMUS, a Phase 3, randomized, double-blind, placebo-controlled, parallel, multicenter trial, evaluated the efficacy and safety of STELARA in adolescent patients 12 to 17 years of age with moderate to severe plaque psoriasis. Patients (N=110) had been diagnosed with psoriasis more than six months prior to first study agent administration and had a Psoriasis Area Severity Index (PASI) score greater than or equal to 12, a Physician's Global Assessment (PGA) score greater than or equal to 3 and body surface area (BSA) involvement of at least 10 percent. In addition, patients were inadequately controlled with topical therapy or were candidates for systemic/phototherapy.

A Phase 3 study, CADMUS Jr, evaluated the efficacy and safety of STELARA in the treatment of pediatric patients 6 to 11 years of age living with moderate to severe plaque psoriasis.

About PSUMMIT
Two Phase 3 multicenter, randomized, double-blind, placebo-controlled trials of STELARA in adult patients with active psoriatic arthritis, PSUMMIT I and PSUMMIT II, evaluated the efficacy and safety of subcutaneously administered STELARA 45 mg or 90 mg at weeks 0, 4 and then every 12 weeks. The trials included adult patients diagnosed with active psoriatic arthritis who had at least five tender and five swollen joints and C-reactive protein (CRP) levels of at least 0.3 mg/dL despite previous treatment with conventional therapy. PSUMMIT II also included adult patients with previous exposure to tumor necrosis factor (TNF) inhibitors. The primary endpoints for both studies were the proportion of patients demonstrating at least a 20 percent improvement in arthritis signs and symptoms [American College of Rheumatology (ACR) 20] at week 24. Secondary endpoints at week 24 included in the submissions were: improvements in Health Assessment Questionnaire Disability Index (HAQ-DI) scores, a 50 or 70 percent improvement in arthritis signs and symptoms (ACR 50 or ACR 70), and at least a 75 percent improvement in psoriatic skin lesions as measured by the Psoriasis Area Severity Index (PASI 75) in patients with at least three percent body surface area involvement at baseline.
