SPRING HOUSE - The Janssen Pharmaceutical Companies of Johnson & Johnson today announced new TREMFYA (guselkumab) efficacy and safety data from the Phase 3b COSMOS trial published in Annals of the Rheumatic Diseases (ARD), evaluating this selective interleukin (IL)-23

inhibitor in adults with active psoriatic arthritis (PsA) who demonstrated inadequate efficacy or intolerance to tumor necrosis factor inhibition (TNFi).1 Results showed significantly higher proportions of patients treated with TREMFYA had improvement in joint signs and symptoms and complete skin clearance versus placebo at week 24 in this documented TNFi-IRa patient population, which is often more difficult to treat.1

Furthermore, improvements in signs and symptoms of PsA were maintained or numerically increased through one year (week 48) among TREMFYA-randomized patients.1

'Active psoriatic arthritis is a heterogenous disease and a significant number of patients do not respond adequately to TNF inhibition,' said lead author Laura Coates, M.D., Ph.D., Associate Professor, University of Oxford, UK.b 'The COSMOS data demonstrate that TREMFYA significantly improved signs and symptoms of active psoriatic arthritis across multiple clinical disease domains, including patient reported outcomes, with treatment effects observed by week four. These findings reinforce the utility of this alternative mechanism of action as a therapeutic option for adults with active psoriatic arthritis who have not responded to one or more therapies.'

About Active Psoriatic Arthritis (PsA)

Active PsA is a chronic, immune-mediated inflammatory disease characterized by peripheral joint inflammation, enthesitis (pain where the bone, tendon and ligament meet), dactylitis (severe inflammation of the fingers and toes), axial disease, and the skin lesions associated with plaque PsO.11-13 In addition, in patients with active PsA, comorbidities, such as obesity, cardiovascular diseases, anxiety and depression are often present.14 Studies show up to 30 percent of people with plaque PsO also develop active PsA.14 The disease causes pain, stiffness and swelling in and around the joints; it commonly appears between the ages of 30 and 50, but can develop at any time.15
