SPRING HOUSE, PENNSYLVANIA, November 10, 2022 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced a new post-hoc analysis of the Phase 3 DISCOVER-2 study that show early (week 8) clinical improvements^a of most measures (joint and skin disease, enthesitis and dactylitis) in adult patients with active psoriatic arthritis (PsA) treated with TREMFYA^® (guselkumab) were associated with meaningful improvements in health-related quality of life (HRQoL) (measured by EQ-5D)^b from year one (week 52) through year two (week 100).¹ TREMFYA is the first fully human selective interleukin (IL)-23 inhibitor therapy approved in the U.S. for adults with active PsA and adults with moderate to severe plaque psoriasis (PsO).²

People with active PsA can experience both physical and mental health challenges that can interfere with their daily lives and impact their work and relationships. Additionally, some patients experience fatigue – a burdensome symptom that often can be underestimated and underreported.³

In a separate post-hoc analysis of DISCOVER-2, clinically meaningful improvements in fatigue (measured by Functional Assessment of Chronic Illness Therapy-Fatigue [FACIT-F])^c observed at one year in TREMFYA-treated patients were enhanced through two years, resulting in greater proportions of patients achieving normative FACIT-F levels.⁴

“Patients with active psoriatic arthritis may struggle with engaging in everyday tasks as a result of health-related quality of life symptoms often associated with the disease,” said Philip J. Mease^d, M.D., Swedish Medical Center/Providence St. Joseph Health and University of Washington in Seattle, Washington. “In these analyses, we see that achieving early clinical strides in distinct symptom domains may demonstrate future gains in health-related quality of life and fatigue improvement, which underscores the important role this therapy plays in the management of the multiple and complex symptoms of active psoriatic arthritis.”

These new analyses of DISCOVER-2 data presented at the 2022 American College of Rheumatology (ACR) Convergence meeting, taking place in Philadelphia, PA and virtually, November 10-14, 2022, show:

Improvements in Health-Related Quality of Life Through Two Years
In DISCOVER-2, biologic-naïve patients with active PsA who were randomized to TREMFYA:¹

• Early (week 8) response in distinct active PsA domains differentially impacted specific components of HRQoL (e.g. EQ-5D, SF-36, DLQI)^b,e over two years versus placebo.
• Statistically significant improvements in overall and physical HRQoL were observed among early clinical responders across several active PsA domains including joint and skin disease, enthesitis, and dactylitis, versus placebo.
• Despite differences in HRQoL observed among early clinical responders and non-early responders, non-early responders also saw benefit in long-term HRQoL with TREMFYA versus placebo.

Clinically Meaningful Improvements in Fatigue Through Two Years
In DISCOVER-2 patients with active PsA and elevated measures of fatigue:⁴

• TREMFYA provided statistically significant benefit over placebo for reducing fatigue as early as week 8 (nominal P-values).
• FACIT-F scores continued to improve between week 24 and week 52 in TREMFYA-treated patient groups.
• The clinically meaningful improvements in fatigue seen at week 52 in TREMFYA-treated patients were further enhanced through week 100, resulting in greater proportions of patients achieving normative FACIT-F levels.
• Improvement of ≥2 points in FACIT-F by week 8 predicted clinically meaningful improvement of ≥4 points at week 100.
• Early targets in FACIT-F levels achieved at 8 weeks of TREMFYA treatment were identified as a potential predictor of later response.

“The burden of active psoriatic arthritis on a patient’s quality of life makes the task of effectively managing the debilitating symptoms of this disease all the more urgent and challenging,” said Terence Rooney, M.D., Vice President, Rheumatology and Maternal-Fetal Immunology Disease Area Leader, Janssen Research & Development, LLC. “These analyses from DISCOVER-2 provide patients and physicians with critical insights as they consider the most appropriate treatment option to manage physical symptoms and help improve overall well-being.”

Editor’s Notes: 
a. Early (week 8) clinical improvement was defined as any of the following:

• ≥20% improvement in swollen joint count (SJC), tender joint count (TJC), patient pain visual analogue scale (VAS), patient Skin VAS, Health Assessment Questionnaire-Disability Index (HAQ-DI)
• ≥4-point improvement in FACIT-F measure¹
• Minimal clinically important improvement in clinical Disease Activity in PsA (cDAPSA, ≥5.7) composite score¹
• Change (reduction) in the Leeds enthesitis index (LEI) or dactylitis severity score (DSS)¹

b. EQ-5D is a preference-based HRQoL measure with one question for each of the five dimensions that include mobility, self-care, usual activities, pain/discomfort and anxiety/depression.⁵

c. FACIT-F Scale: measured on a 4-point Likert scale (4 = not at all fatigued to 0 = very much fatigued).⁶

d. Dr. Mease is a paid consultant for Janssen. He has not been compensated for any media work.

e. Dermatology Life Quality Index (DLQI) is a self-administered questionnaire for patients to score the impact of PsO on their quality of life. The higher the score, the more quality of life is affected. Scores may range from 0-1, indicating no effect of PsO on a patient’s life, to 21-30, indicating many aspects of their life are severely affected by PsO.⁷

f. The PASI score grades the combination of the amount of surface area covered by PsO plaques in each body region, and the degree of plaque redness, thickness, and scaliness to assess the extent and severity of PsO.⁸

About DISCOVER-2 (NCT03158285)⁹
DISCOVER-2 is a randomized, double-blind, multicenter Phase 3 study evaluating the efficacy and safety of TREMFYA administered by SC injection in biologic-naïve patients with active PsA. DISCOVER-2 evaluated 739 participants who were treated and followed through approximately two years. The study consisted of a screening phase of up to six weeks, a blinded treatment phase of approximately 100 weeks that included a placebo-controlled period from week 0 to week 24 and a blinded active treatment period from week 24 to week 100. It also included a safety follow-up phase through week 112 (i.e., approximately 12 weeks after the last administration of study agent at week 100). Clinical efficacy, radiographic efficacy, health economics, safety, pharmacokinetics, immunogenicity, biomarker, and pharmacogenomics evaluations were performed in the study on a defined schedule.¹⁰

About Psoriatic Arthritis (PsA)
PsA is a chronic, immune-mediated inflammatory disease characterized by peripheral joint inflammation, enthesitis (pain where the bone, tendon and ligament meet), dactylitis (a type of inflammation in the fingers and toes that can result in a swollen, sausage-like appearance), axial disease, and the skin lesions associated with plaque PsO.^11-132 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 age.¹⁴³ Nearly half of patients with PsA experience moderate fatigue and about 30 percent suffer from severe fatigue as measured by the modified fatigue severity scale.¹⁴³ In patients with PsA, comorbidities, such as obesity, cardiovascular diseases, anxiety and depression are often present.¹⁵⁴ Studies show up to 30 percent of people with plaque PsO also develop PsA.¹⁶⁵ Although the exact cause of PsA is unknown, genes, the immune system and environmental factors are all believed to play a role in disease onset.¹⁷

About TREMFYA^® (guselkumab)¹
Developed by Janssen, TREMFYA is the first approved fully human monoclonal antibody that selectively binds to the p19 subunit of IL-23 and inhibits its interaction with the IL-23 receptor. IL-23 is an important driver of the pathogenesis of inflammatory diseases such as moderate to severe plaque PsO and active PsA. TREMFYA is approved in the U.S., Canada, Japan, and a number of other countries worldwide for the treatment of adults with moderate to severe plaque PsO who are candidates for injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light), and for the treatment of adult patients with active PsA. It is also approved in the EU for the treatment of moderate to severe plaque PsO in adults who are candidates for systemic therapy and for the treatment of active PsA in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.
