New Phase 3 Data Showed First-in-Class TREMFYA® (guselkumab) Provided Durable Complete Skin Clearance Through Five Years in Moderate to Severe Plaque Psoriasis (PsO)

SPRING HOUSE, Pa., April 23, 2021 /PRNewswire/ -- The Janssen Pharmaceutical Inc. of Johnson & Johnson today announced new Phase 3 data which showed TREMFYA^® (guselkumab) sustained durable, complete skin clearance rates in a majority of adults with moderate to severe plaque psoriasis (PsO) through five years (252 weeks), ^a and improved disease activity and axial symptoms in adults with active psoriatic arthritis (PsA) through one year (52 weeks).^1,2,3 These data are being presented at the American Academy of Dermatology Virtual Meeting Experience 2021, where Janssen will present a total of 22 abstracts. TREMFYA is the first and only selective interleukin (IL)-23 inhibitor therapy approved in the U.S. to treat both adults with moderate to severe plaque PsO who are candidates for systemic therapy or phototherapy and adults with active PsA.⁴

“People living with psoriatic disease can face a lifetime of physical pain and discomfort, which places a significant burden on their lives,” said Kristian Reich,^b M.D., Ph.D., Professor of Translational Research in Inflammatory Skin Diseases, Institute for Health Services Research in Dermatology and Nursing, University Medical Center Hamburg-Eppendorf, Germany, and lead author of the VOYAGE 2 study. “The signs and symptom improvements seen with TREMFYA are noteworthy for both patients who live with fear of disease recurrence and their physicians, as these data add to a growing body of evidence for this first-in-class IL-23 inhibitor treatment for moderate to severe plaque psoriasis and active psoriatic arthritis.”

Results show:

• Durable and Complete Skin Clearance Rates: In the PsO trial VOYAGE 2 (POSTER #27859), 55.5 percent of patients in the TREMFYA group^c achieved an Investigator’s Global Assessment (IGA)^d score of 0, indicating complete skin clearance, and 53 percent achieved a Psoriasis Area Severity Index (PASI)^e 100 skin clearance response (PASI 100) at week 252.¹ Additionally, in the same trial, 82 percent achieved a PASI 90 skin clearance response and 85 percent achieved an IGA score of 0/1 (clear/almost clear).¹ High efficacy rates were maintained through five years of TREMFYA treatment based on analyses using pre-specified treatment failure rules (patients discontinuing due to lack of efficacy, worsening of PsO, or use of a prohibited treatment were considered non-responders).¹
• Robust Joint Symptom Improvement: TREMFYA 100 mg every four weeks^f and every eight weeks improved PsA disease activity in joints and across multiple domains through week 52 in both PsA trials, DISCOVER-1 and -2, as measured by the Disease Activity Index for PsA, Minimal Disease Activity, Very Low Disease Activity and remission determined using Disease Activity Index for PsA (POSTER #27038).² Differences in response rates associated with composite indices between TREMFYA and placebo were seen as early as week eight and increased over time through week 52.² In addition, data from a separate abstract show TREMFYA is the first IL-23 inhibitor to provide sustained improvements in PsA axial symptoms based on change from baseline in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI)^g score and percentage of patients achieving a BASDAI 50 response through week 52 (POSTER #27851).³
• Established Safety Profile: Across both PsO trials, VOYAGE 1 and 2, 78.4 percent of patients (n=1,349/1,721) with moderate to severe plaque PsO treated with TREMFYA continued treatment through week 252 (7,166 patient-years of follow-up).⁵ This comprehensive safety analysis of VOYAGE 1 and 2 showed a consistent safety profile for TREMFYA from year one through year five with low rates of adverse events (AEs) leading to discontinuation and serious AEs (POSTER #28095).⁵

“The durable response rates seen in the majority of patients enrolled in the VOYAGE and DISCOVER trials further demonstrate the important role that TREMFYA has in helping patients with their moderate to severe plaque psoriasis and their active psoriatic arthritis and add to the volume of scientific insights provided by the comprehensive TREMFYA research program,” said Lloyd S. Miller, M.D., Ph.D., Vice President, Immunodermatology Disease Area Leader, Janssen Research & Development, LLC.

Editor’s Note:

a. VOYAGE 2 included a randomized withdrawal phase and some patients had treatment interrupted; all resumed treatment by week 76. Starting at 76 weeks and thereafter, patients and study investigators knew that all study participants were on TREMFYA.¹

b. Dr. Reich is a paid consultant for Janssen. He was not compensated for any media work.

c. The TREMFYA group included patients who were initially randomized to receive TREMFYA at week 0 and patients who were initially randomized to placebo then crossed over to TREMFYA at week 16.

d. Investigator’s Global Assessment (IGA Score) is a five-point scoring system used to characterize psoriasis severity. Scores range from 0 to 5 and represent cleared (0), almost clear (1), mild (2), moderate (3), severe (4) and very severe (5).⁶

e. PASI 75/90/100 responses are defined as at least 75/90/100 percent improvement in the PASI score from baseline. The PASI score grades the amount of surface area covered by PsO plaques in each body region, and the degree of plaque redness, thickness, and scaliness.⁷

f. TREMFYA is FDA approved for administration as a 100 mg subcutaneous (SC) injection every eight weeks, following two starter doses at weeks 0 and 4.²

g. BASDAI consists of a 0-10 scale (0 being no problem and 10 being the worst problem) which is used to answer 6 questions pertaining to the major symptoms of ankylosing spondylitis: fatigue, spinal pain, joint pain, enthesitis, morning stiffness and duration of morning stiffness.⁸

About Psoriasis
PsO is an immune-mediated disease resulting in an overproduction of skin cells, which causes raised, red, scaly plaques that may be itchy or painful.⁹ It is estimated that 8 million Americans and more than 125 million people worldwide live with the disease.¹⁰ Nearly one-quarter of all people with PsO have cases that are considered moderate to severe.¹⁰ Living with PsO can be a challenge and impact life beyond a person’s physical health, including emotional health, relationships, and handling the stressors of life.¹¹

About Psoriatic Arthritis
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 PsO.^12,13,14 In addition, in patients with PsA, comorbidities such as obesity, cardiovascular diseases, anxiety and depression are often present.¹⁵ Studies show up to 30 percent of people with PsO also develop PsA.¹⁶ 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.¹⁶ 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.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.¹⁸

About VOYAGE 2 (NCT02207244)¹⁹
This Phase 3, randomized, double-blind, placebo and active comparator-controlled trial was designed to evaluate the efficacy and safety of TREMFYA compared with placebo and adalimumab in adults with moderate to severe plaque PsO. Patients (N=992) were randomized to receive SC injections of TREMFYA 100 mg (n=496) at weeks 0, 4 and every 8 weeks (q8w) thereafter; placebo (n=248) at weeks 0, 4, and 12 followed by crossover to TREMFYA 100 mg at week 16; or adalimumab 80 mg (n=248) at week 0, 40 mg at week 1, then 40 mg every 2 weeks (q2w) until week 23. Weeks 28-72 incorporated a randomized withdrawal study design. During the open-label period (weeks 76-252), all patients received TREMFYA 100 mg q8w. Physician- and patient-reported outcomes were assessed. Efficacy was analyzed using pre-specified treatment failure rules (patients discontinuing due to lack of efficacy, worsening of PsO, or use of a prohibited treatment were considered non-responders). Data were combined for patients randomized to TREMFYA and for those originally randomized to placebo who later crossed over to TREMFYA at week 16. Patients were treated and followed for up to 264 weeks.

Co-primary endpoints of the study were proportions of patients receiving TREMFYA vs. patients receiving placebo achieving IGA 0/1 (clear/almost clear) [84 percent vs. 9 percent, respectively; p<0.001 vs. placebo] and PASI 90 [70 percent vs. 2 percent, respectively; p<0.001 vs. placebo] at week 16. Additional efficacy assessments included proportions of patients achieving PASI 75, and PASI 100 responses, as well as IGA scores of 0, a Dermatology Life Quality Index (DLQI) score of 0/1, a Psoriasis Signs and Symptoms Diary (PSSD) score of 0, the 36-Item Short-Form Health Survey (SF36), Hospital Anxiety and Depression scale (HADs) and the Work Limitations Questionnaire (WLQ). Efficacy was analyzed using pre-specified treatment failure rules, non-responder imputation, and as observed methodology.

VOYAGE 2 is part of a comprehensive Phase 3 clinical development program for TREMFYA in moderate to severe plaque PsO that includes VOYAGE 1, NAVIGATE, and ECLIPSE.^20,21,22

About DISCOVER-1 (NCT03162796)²³
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 tumor necrosis factor (TNF) inhibitors. DISCOVER-1 evaluated 381 participants who were treated and followed through approximately one year. The primary endpoint was response of American College of Rheumatology (ACR) 20 at week 24 and primary endpoint data was previously presented at scientific congresses. In addition to ACR20, multiple other clinical outcomes were assessed, including ACR50/70, resolution of soft tissue inflammation, enthesitis and dactylitis, improvement in physical function, skin clearance (IGA), and general health outcomes (36-Item Short-Form Health Survey [SF-36] Physical Component Summary [PCS] and Mental Component Summary [MCS]).

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)²⁴
DISCOVER-2 was a randomized, double-blind, multicenter Phase 3 study evaluating the efficacy and safety of TREMFYA administered by SC injection in bio-naïve patients with active PsA. DISCOVER-2 evaluated 739 participants who were treated and followed through approximately two years. The primary endpoint was response of ACR 20 at week 24 and primary endpoint data was previously presented at scientific congresses. In addition to ACR20, multiple other clinical outcomes were assessed, including ACR50/70, resolution of soft tissue inflammation, enthesitis and dactylitis, improvement in physical function, skin clearance (IGA), and general health outcomes (SF-36 PCS and MCS). DISCOVER-2 also assessed changes in structural damage as a key secondary endpoint (van der Heijde-Sharp score).

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 TREMFYA^® (guselkumab)⁴
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 PsO and PsA.²⁵

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.
