Spring House, Pennsylvania , February 7, 2024 —Johnson & Johnson today announced publication in the New England Journal of Medicine (NEJM) of the Phase 2b FRONTIER 1 trial results for JNJ-2113.1 JNJ-2113 is the first and only investigational targeted oral peptide inhibitor designed to block the IL-23 receptor.2 IL-23 plays a critical role in pathogenic T-cell activation in moderate-to-severe plaque psoriasis (PsO) and underpins the inflammatory response in PsO and other dermatological and gastroenterological IL-23-mediated diseases.3,4 The FRONTIER 1 clinical trial achieved the primary and all secondary efficacy endpoints evaluating JNJ-2113 in adults with moderate-to-severe plaque PsO.1
The primary endpoint of the study was a reduction from baseline of at least 75 percent in the Psoriasis Area and Severity Index score (PASI 75 response) at Week 16. Study results demonstrated a significant dose-response on PASI 75 at Week 16 for adult patients who received JNJ-2113 compared to patients treated with placebo, with 79 percent of patients achieving a PASI 75 response in the highest dose group tested of 100 mg twice-daily. The data were consistent with the secondary endpoints, with patients who received the highest dose of JNJ-2113 achieving PASI 100 of 40.5 percent and IGA 0 (clear skin) of 45.2 percent.1
“The science behind advanced treatments for immune-mediated inflammatory diseases like PsO has advanced over the last few decades and patients desire treatment options that combine standard of care efficacy, an acceptable safety profile and flexible routes of administration,” said Robert Bissonnette, M.D., Chief Executive Officer and Medical Director at Innovaderm Research, Montreal, Canada.d “The Phase 2b FRONTIER 1 data, as reported in NEJM, are very encouraging for the ongoing clinical development program and offer a reason to look forward to the continued research of investigational JNJ-2113 as an oral therapy that may offer an attractive and convenient treatment option for patients.”
Improvements were also consistent across Patient Reported Outcomes through Week 16.1 Patients who were treated with JNJ-2113 demonstrated greater improvements from baseline in the severity of their disease-related symptoms by Week 16, as assessed by the Psoriasis Symptoms and Signs Diary (PSSD)c.1 Among patients with baseline Dermatology Life Quality Index (DLQI)e scores greater than 1, significantly higher proportions of JNJ-2113-treated patients compared with placebo-treated patients achieved DLQI scores of 0/1 (no impact on quality of life) at Week 16.1
In this phase 2 study, rates of adverse events (AEs) were generally similar between the JNJ-2113 and placebo groups.1 The most common (≥5 percent of any treatment group) AEs were COVID-19 infection, nasopharyngitis, upper respiratory tract infection, diarrhea, headache, and cough.1 No relationship between the JNJ-2113 dose group and the occurrence of AEs or serious AEs was observed.1
Treatment with JNJ-2113 was also associated with lower serum levels of human beta-defensin 2 (hBD-2), relative to placebo, as early as Week 4.1 The lowest hBD-2 level was observed with the 100 mg twice-daily dose, beginning by Week 8.1 Lower levels of hBD-2 were observed with clinical response and indicate inhibition of the IL-17/IL-23 axis.5,6,7
“The impacts of living with moderate-to-severe plaque PsO are felt across all aspects of life and many patients do not seek advanced treatments because they have concerns with injectables and prefer an oral therapeutic option,” said Lloyd Miller, M.D., Ph.D., Vice President, Immunodermatology Disease Area Leader, Johnson & Johnson. “We are encouraged by the study findings published in NEJM, including consistency across clinician and patient-reported outcomes and objective biomarkers. If approved, JNJ-2113 has the potential to improve both clinical and quality of life outcomes.”
The pivotal Phase 3 ICONIC clinical development program of JNJ-2113 in adult and adolescent patients with moderate-to-severe plaque PsO was initiated with two studies in Q4 2023 – ICONIC-LEAD and ICONIC-TOTAL – pursuant to the license and collaboration agreement between Protagonist Therapeutics, Inc. and Janssen Biotech, Inc.8 ICONIC-LEAD is a randomized controlled trial (RCT) to evaluate the safety and efficacy of JNJ-2113 compared with placebo in participants with moderate-to-severe plaque PsO, with the higher efficacy bar of PASI 90 and IGA score of 0 or 1 with at least a 2-grade improvement as co-primary endpoints.9 ICONIC-TOTAL is a RCT to evaluate the efficacy and safety of JNJ-2113 compared with placebo for the treatment of PsO in participants with at least moderate severity affecting special areas (e.g., scalp, genital, and/or palms of the hands and the soles of the feet) with overall IGA score of 0 or 1 with at least a 2-grade improvement as the primary endpoint.10 Other Phase 3 studies in the development program are expected to begin in Q1 2024, including ICONIC-ADVANCE 1 and ICONIC-ADVANCE 2, which will evaluate the safety and efficacy of JNJ-2113 compared with both placebo and deucravacitinib.11
The findings from the FRONTIER 1 clinical trial suggest the potential of JNJ-2113 across the spectrum of additional IL-23-mediated diseases.2,12 The Company has initiated the Phase 2b ANTHEM-UC study to evaluate the safety and effectiveness of JNJ-2113 compared with placebo in participants with moderately to severely active ulcerative colitis.12
Editor’s Notes:
a. The PASI score grades the amount of surface area on each body region that is covered by PsO plaques and the severity of plaque redness, thickness, and scaliness.13
b. The IGA is a five-point scale with a severity ranging from 0 to 4, where 0 indicates clear, 2 is mild, 3 is moderate, and 4 indicates severe disease.1
c. The PSSD is a patient-reported instrument that assesses severity of six symptoms (itch, skin tightness, burning, stinging, and pain) and five signs (dryness, cracking, scaling, shedding/flaking, redness, and bleeding) of PsO. An improvement (reduction) of 40 points or more is considered clinically meaningful.1
d. Dr. Robert Bissonnette is a paid consultant for Johnson & Johnson. He has not been compensated for any media work.
e. The DLQI measures impact of any skin disease on daily life, and assesses symptoms, feelings, daily activities, leisure, work/school, relationships/sex, and treatment effects.14
About FRONTIER 1 (NCT05223868)
The FRONTIER 1 Phase 2b trial (NCT05223868) is a randomized, multicenter, double-blind, placebo-controlled clinical trial that evaluated three once-daily dosages and two twice-daily dosages of JNJ-2113 taken orally.1,15 It was designed to assess the efficacy and safety of JNJ-2113 in patients with moderate-to-severe plaque PsO.1 A total of 255 participants were randomized into six treatment groups (placebo [n=43], 25 mg daily [n=43], 25 mg twice-daily [n=41], 50 mg daily [n=43], 100 mg daily [n=43], and 100 mg twice-daily [n=42]).1 The total duration of the trial was up to 24 weeks, which included a four-week screening period, a 16-week treatment period and a four-week safety follow-up period.1
The primary endpoint of the clinical trial was the proportion of patients achieving PASI 75 at 16 weeks.1 Secondary endpoints at Week 16 included change from baseline in PASI total score, proportion of participants achieving PASI 90 and PASI 100 score, proportion of participants achieving an Investigator’s Global Assessment (IGA) score of cleared (0) or minimal (1), change from baseline in Body Surface Area (BSA), change from baseline in Psoriasis Symptoms and Signs Diary (PSSD) symptoms scores, percentage of participants achieving PSSD symptoms score=0 among participants with a baseline symptom score ≥1, proportion of participants achieving a Dermatology Life Quality Index (DLQI) of 0 or 1 among participants with baseline DLQI Score >1, change from baseline in Patient-Reported Outcomes Measurement Information System (PROMIS-29) domain score, proportion of participants who achieve ≥ 5-point improvement from baseline in PROMIS-29 domain score, and number of participants with adverse events and serious adverse events up to 24 weeks.15
About Plaque Psoriasis (PsO)
Plaque PsO is an immune-mediated disease resulting in overproduction of skin cells, which causes inflamed, scaly plaques that may be itchy or painful.16 It is estimated that eight million Americans and more than 125 million people worldwide live with the disease.15 Nearly one-quarter of all people with PsO have cases that are considered moderate-to-severe.17 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.18
