STELARA® Phase 3 Study Published In The Lancet Reports One Year Efficacy And Safety In Treatment Of Active Psoriatic Arthritis Data Show Interleukin-12/23 Inhibitor STELARA Improved Joint, Soft Tissue and Skin Components of Psoriatic Arthritis PR Newswire SPRING HOUSE, Pa., June 13, 2013 SPRING HOUSE, Pa., June 13, 2013 /PRNewswire/ -- Results from a Janssen Research & Development, LLC (Janssen)-sponsored Phase 3 study published today in The Lancet showed patients with active psoriatic arthritis who received either STELARA^® (ustekinumab) 45 mg or 90 mg achieved significant improvement in joint symptoms at the study's primary endpoint compared with patients receiving placebo. According to findings from the investigational study, continued treatment with STELARA every 12 weeks resulted in improvements in signs and symptoms of active disease and psoriasis symptoms through one year. In December 2012, Janssen announced submissions to health authorities in the United States and Europe seeking approval of STELARA, an interleukin (IL)-12/IL-23 inhibitor, for the treatment of active psoriatic arthritis. STELARA is approved for the treatment of adults with moderate to severe plaque psoriasis in 72 countries. "Data from the PSUMMIT I Phase 3 study showed that STELARA significantly improved the joint and skin manifestations of psoriatic arthritis, and a significant proportion of patients maintained improvement in disease symptoms through one year," said lead study investigator Iain B. McInnes, PhD, FRCP, Professor of Medicine, and Director of the Institute of Infection, Immunity, and Inflammation, University of Glasgow, Scotland. "STELARA remains an investigational therapeutic for psoriatic arthritis, and may represent an important future option and alternative mechanism to currently available therapies, pending health authority approval." During the induction portion of the Phase 3 Multicenter, Randomized, Double-blind, Placebo-controlled trial of Ustekinumab, a Fully Human anti-IL-12/23p40 Monoclonal Antibody, Administered Subcutaneously, in Subjects with Active Psoriatic Arthritis (PSUMMIT I) study, patients were randomized to receive subcutaneous STELARA 45 mg or 90 mg or placebo at weeks 0, 4 and then every 12 weeks. By week 24, all patients receiving placebo were crossed over to receive STELARA. At week 24, 42.4 percent and 49.5 percent of patients receiving STELARA 45 mg and 90 mg, respectively, achieved at least 20 percent improvement in signs and symptoms according to the American College of Rheumatology criteria (ACR 20), the primary endpoint, compared with 22.8 percent of patients receiving placebo (P < 0.0001 for both comparisons). Improvement in signs and symptoms continued to increase after week 24, with 55.7 percent and 60.3 percent of patients in the STELARA 45 mg and STELARA 90 mg groups, respectively, demonstrating ACR 20 response at week 52. ACR 50 (at least a 50 percent improvement in signs and symptoms according to the ACR criteria) and ACR 70 (at least a 70 percent improvement in signs and symptoms according to the ACR criteria) response rates also increased over time among patients receiving STELARA maintenance therapy. At week 24, 24.9 percent and 27.9 percent of patients receiving STELARA 45 mg and 90 mg, respectively, achieved ACR 50 compared with 8.7 percent of patients receiving placebo (P < 0.0001 for both comparisons). Improvement in signs and symptoms continued to increase after week 24, with 31.4 percent and 37 percent of patients in the STELARA 45 mg and STELARA 90 mg groups, respectively, demonstrating ACR 50 response at week 52. At week 24, 12.2 percent and 14.2 percent of patients receiving STELARA 45 mg and 90 mg, respectively, achieved ACR 70 compared with 2.4 percent of patients receiving placebo (P < 0.0001 for both comparisons). Improvement in signs and symptoms continued to increase after week 24, with 18 percent and 21.2 percent of patients in the STELARA 45 mg and STELARA 90 mg groups, respectively, demonstrating ACR 70 response at week 52. Investigators reported improvements in physical function and skin symptoms throughout the study in both STELARA treatment groups. Nearly half of patients receiving treatment with STELARA demonstrated a clinically meaningful change from baseline in the Health Assessment Questionnaire Disability Index (HAQ-DI) at both weeks 24 and 52. Significantly more patients with at least three percent body surface involvement of psoriasis at baseline achieved at least a 75 percent improvement in psoriasis symptoms as measured by the Psoriasis Area Severity Index (PASI 75) at week 24 [57.2 percent and 62.4 percent of patients receiving STELARA 45 mg and 90 mg, respectively, compared with 11 percent of patients receiving placebo (P < 0.0001 for both comparisons), and more than two-thirds of patients across all treatment groups achieved PASI 75 through week 52. Among study participants affected with enthesitis (inflammation of the entheses, the sites where tendons or ligaments attach to bone, n=425) or dactylitis (inflammation of the finger or toe, n=286) at baseline, patients receiving STELARA achieved clinically relevant improvements in both measures at week 24 and week 52. At week 24, percent improvement in enthesitis scores (median: 42.9 percent for STELARA 45 mg and 50 percent for STELARA 90 mg) and dactylitis scores (75 percent for STELARA 45 mg and 70.8 percent for STELARA 90 mg) were significantly higher than those seen for patients receiving placebo (P = 0.0019 and P < 0.0001, respectively, for enthesitis comparisons; P = 0.0003 for both dactylitis comparisons). Median percent improvements in enthesitis scores (83.3 percent and 74.2 percent) and dactylitis scores (100 in both dose groups) in the STELARA 45 mg and 90 mg groups, respectively, continued through week 52. The trial had a placebo-controlled period of 16 weeks after which some non-responding, placebo-treated patients were switched to the STELARA 45 mg regimen. Through this 16-week placebo-controlled period, 40 percent and 43.6 percent of patients receiving STELARA 45 mg or STELARA 90 mg, respectively, experienced at least one adverse event (AE) compared with 42 percent of patients receiving placebo. Through week 16, the percentages of patients experiencing at least one serious AE were reported as 2 percent in the STELARA 45 mg group, 1.5 percent in the STELARA 90 mg group and 2 percent in the placebo group. Safety through week 52 was consistent with that observed during the placebo-controlled period. No malignancies, cases of tuberculosis (TB), opportunistic infections or deaths occurred through week 52. After the placebo-controlled period, major adverse cardiovascular events (MACE) were reported in three patients with multiple pre-existing cardiovascular risk factors who were receiving STELARA 45 mg dosing. About PSUMMIT I The PSUMMIT I trial is a Phase 3, multicenter, randomized, double-blind, placebo-controlled study including 615 adults with active psoriatic arthritis designed to evaluate the efficacy and safety of STELARA. The trial included 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 (upper limit of normal [ULN] 1.0 mg/dL) despite treatment with disease-modifying antirheumatic drugs (DMARDs) and/or nonsteroidal anti-inflammatory drugs (NSAIDs). Patients were naive to treatment with anti-TNF-alpha therapies and/or IL-12/23 inhibitors. Patients were randomized to three groups: STELARA 45 mg or STELARA 90 mg at weeks 0, 4 and then every 12 weeks or placebo. Patients with less than a five percent improvement in tender and swollen joint counts at week16 were considered non-responders for the primary and major secondary analyses at week 24. Patients with less than a five percent improvement in tender and swollen joint counts at week16 who were receiving placebo were switched to STELARA 45 mg, and patients receiving STELARA 45 mg were switched to 90 mg. Patients receiving STELARA 90 mg remained on the 90 mg dosing regimen. The primary endpoint was ACR 20 response at week 24. Secondary endpoints at week 24 included ACR 50 and ACR 70 response, Disease Activity Score (DAS) 28-CRP response, PASI 75 in patients with at least three percent body surface area involvement at baseline, improvements in enthesitis and dactylitis scores and improvements in Health Assessment Questionnaire-Disability Index (HAQ-DI) scores. Following week 24 assessment, patients receiving STELARA 45 mg and 90 mg continued to receive every-12-week maintenance therapy, and placebo patients were crossed over to receive STELARA 45 mg induction (at weeks 24 and 28) and maintenance therapy every 12 weeks thereafter. Safety and efficacy results were reported through week 52 in the trial. About Psoriatic Arthritis Psoriatic arthritis is a chronic immune-mediated inflammatory disease characterized by both joint inflammation and the skin lesions associated with psoriasis that affects up to 37 million people worldwide. While estimates of the prevalence of psoriatic arthritis among people living with psoriasis vary, up to 30 percent may develop inflammatory arthritis. The disease causes pain, stiffness and swelling in and around the joints and commonly appears between the ages of 30 and 50, but can develop at any time. Though the exact cause of psoriatic arthritis is unknown, genes, the immune system and environmental factors are all believed to play a role in the onset of the disease. About STELARA (ustekinumab) STELARA, a human interleukin (IL)-12 and IL-23 antagonist, is approved for the treatment of adult patients (18 years or older) with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy. IL-12 and IL-23 are naturally occurring proteins that are believed to play a role in inflammatory conditions such as psoriasis and psoriatic arthritis. Janssen Biotech, Inc. discovered STELARA and has exclusive marketing rights to the product in the United States. The Janssen Pharmaceutical Companies maintain exclusive worldwide marketing rights to STELARA, which is currently approved for the treatment of moderate to severe plaque psoriasis in 72 countries.
