New TREMFYA® (guselkumab) Post-Hoc Analysis Reveals Early Efficacy Predicted Longer-Term Efficacy And Sustained Achievement Among A Diverse Active Psoriatic Arthritis Patient Population

"Active psoriatic arthritis is a chronic, lifelong condition that can be progressive for many patients, leading to extensive and permanent joint damage," said Philip J. Mease, M.D.,i Swedish Medical Center/Providence St. Joseph Health and University of Washington in Seattle, Washington. "The data derived from TREMFYA-treated patients in the DISCOVER program give us more tools to evaluate treatment plan options that may help facilitate long-term relief as we work toward the ultimate goal of disease remission."

Presented at the 2022 American College of Rheumatology (ACR) Convergence meeting, taking place in Philadelphia, PA and virtually, November 10-14, 2022, these new analyses of DISCOVER-1 and DISCOVER-2 dataj show:Early Skin and Entheseal Responses in TREMFYA-Treated Active PsA Patients May Predict Future Achievement of Rigorous Measures of Disease Control:1

At week 24, early skin responsea was associated with greater odds of achieving MDA, Disease Activity in Psoriatic Arthritis (DAPSA) Low Disease Activity (LDA), DAPSA remission, and DAPSA50k in PsA.

Early entheseal response was associated with greater odds of achieving MDA, DAPSA LDA, DAPSA50, and resolution of enthesitis or dactylitis.

DAPSA remission was achieved by a greater proportion of early entheseal responders, though the association was significant only at week 52.

Among patients with baseline PsO and enthesitis, a dual effect was observed: those who responded early in both domains were more likely to achieve clinical response (MDA, DAPSA LDA, DAPSA50, DAPSA remission) than patients with individual responses to these domains.

These results highlight the importance of early entheseal and skin responses on the trajectory of future patient outcomes.Treatment with TREMFYA Sustained Stringent PsA Disease Control Endpoints Through Two Years Among a Diverse Population of Adults with Active PsA in Post-hoc Analysis of DISCOVER-23:

Sustained achievement of stringent endpoints spanning key GRAPPA-recommended domains, including ACR50 and ACR70, IGA 0, dactylitish and enthesitis resolution, and MDA responses was seen across a variety of diverse, baseline demographicsd (sex, body mass index [BMI]) and disease characteristics (swollen joint count [SJC], tender joint count [TJC], PsA duration, C-reactive protein [CRP], Body Surface Area [BSA], Psoriasis Area and Severity Index [PASI]).

At week 100, sustained achievement of stringent endpoints was observed across all domains (MDA response, IGA 0 and resolution of dactylitis), irrespective of use of concomitant therapies (nbDMARDs and methotrexate [MTX])

No consistent differences were observed in the proportion of responders across patient subgroupsd of adequate sample size or between TREMFYA dosing regimens.

Results of this post-hoc analysis further support the long-term efficacy (week 100) of TREMFYA across the full spectrum of active PsA disease domains and diverse PsA populations.

"These analyses from the DISCOVER program give us greater insight into the potential for TREMFYA to provide long-term efficacy across multiple stringent disease control endpoints in diverse patient groups with active psoriatic arthritis," said Terence Rooney, M.D., Vice President, Rheumatology and Maternal-Fetal Immunology Disease Area Leader, Janssen Research & Development, LLC. "The data underscore Janssen's ongoing commitment to extensive research in active psoriatic arthritis, so that we may provide effective therapeutic options for patients living with the disease."

Editor's Notes:

a. Early skin response was defined as skin visual analogue scale (VAS) <=15mm at week 8 or PASI score ≤1 at week 16.
b. Enthesitis is defined as inflammation where tendons and ligaments meet bone. It is associated with certain kinds of arthritis, including active PsA.4 Early entheseal response was defined as Leeds Enthesitis Index (LEI) score ≤1 at week 8.1
c. Longer-term clinical responses were defined by achievement of MDA,f DAPSA (LDA or remission), DAPSA50k and enthesitis/dactylitis resolution at week 24 or week 52.
d. Baseline characteristics of interest were patient's sex, BMI, swollen joint count (0-66, SJC), tender joint count (0-68, TJC), PsA duration, CRP, percent of BSA with PsO, PASI score, and use of conventional synthetic (cs) DMARDs and MTX.
e. In DISCOVER-2, 739 patients were randomized (1:1:1) and treated with TREMFYA 100 mg q4w (n=245); TREMFYA 100 mg at week 0, week 4, then q8w (n=248); or placebo (n=246) with crossover to TREMFYA 100 mg q4w at week 24.3
f. MDA is defined by fulfillment of 5/7 criteria: TJC ≤1, SJC ≤1, PASI score ≤1, patient pain score ≤15, patient global disease (arthritis and skin) activity score ≤20, Health Assessment Questionnaire–Disability Index (HAQ-DI) score ≤0.5, and ≤1 tender entheses.4
g. Skin clearance was evaluated using an Investigator's Global Assessment score of 0 [clear skin] (IGA 0). The IGA score is a 5-point clinical scale evaluating PsO severity.5
h. Dactylitis involves the swelling of fingers or toes and is associated with active PsA.6
i. Dr. Mease is a paid consultant for Janssen. He has not been compensated for any media work.
j. Please see the 'About DISCOVER-1' and 'About DISCOVER-2' sections for further details regarding study design.
k. DAPSA50 response represents at least 50 percent improvement in the DAPSA score from baseline. The DAPSA score is derived via summation of the following five variables: TJC, SJC, patient global assessment of arthritis (0-10 VAS), and patient assessment of joint pain (0-10 VAS, and CRP level.7
l. Disease activity control was measured by the following endpoints: MDA, ACR50 and ACR70,m IGA 0, PASDAS LDA, resolution of enthesitis and dactylitis, FACIT-F response (≥4-point improvement), and HAQ-DI response (≥0.35-point improvement).
m. ACR50 and ACR70 response criteria require ≥50 percent or ≥70 percent improvement in both the TJC and SJC, as well as in three of the following: patient global assessment of disease (arthritis) activity (VAS), physician global assessment (VAS), patient assessment of pain (VAS), HAQ-DI score, and either erythrocyte sedimentation rate or CRP.8,9About DISCOVER-1 (NCT03162796)10

DISCOVER-1 was a randomized, double-blind, multicenter Phase 3 study evaluating the efficacy and safety of TREMFYA administered by SC injection in participants with active PsA, including those previously treated with one or two TNF inhibitors. DISCOVER-1 evaluated 381 participants who were treated and followed through approximately one year. The study consisted of a screening phase of up to six weeks, a blinded treatment phase of 52 weeks that included a placebo-controlled period from week 0 to week 24 and a blinded active treatment period from week 24 to week 52. It also included a safety follow-up phase through week 60 (i.e., approximately 12 weeks from the last administration of study agent at week 48). Efficacy, safety, pharmacokinetic, immunogenicity and biomarker evaluations were performed in the study on a defined schedule.About DISCOVER-2 (NCT03158285)12

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.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.4,6,14 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 age15. 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.15 In patients with PsA, comorbidities such as obesity, cardiovascular diseases, anxiety and depression are often present.16 Studies show up to 30 percent of people with plaque PsO also develop PsA.17 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.18About TREMFYA® (guselkumab)3

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 csDMARD therapy.
