Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis (IPAA) is considered the procedure of choice in patients with ulcerative colitis (UC) refractory to medical therapy or with neoplasia. The most common complication after IPAA is the development of pouchitis. Pouchitis is clinically characterized by variable symptoms including increased stool frequency, altered consistency, bloody stools, abdominal cramping, urgency, and incontinence. Symptomatic pouchitis longer than four weeks is considered chronic pouchitis.
The conventional treatment for acute and chronic pouchitis is antibiotics, such as metronidazole and ciprofloxacin. The disease course of antibiotic responsive pouchitis may evolve into antibiotic dependent (requiring antibiotic maintenance therapy) pouchitis and then antibiotic refractory (no response to antibiotic treatment) pouchitis. Although many patients respond to antibiotic therapy, there is also evidence that suggest that aberrant regulation of the mucosal immune system might play a part in the pathogenesis of pouchitis arising from an abnormal mucosal immune response to a dysbiosis of the pouch microbiota. If individuals fail to respond to antibiotics, anti-tumor necrosis factor (anti-TNF) agents and vedolizumab have been proposed for the treatment of chronic pouchitis.
Guselkumab, an interleukin-23 (IL-23) p19 subunit antagonist monoclonal antibody, is proven to be efficacious in patients with moderately-to-severely active UC. Efficacy of guselkumab in treating UC has been shown in multiple large clinical trials. However, patients with pouchitis were never the targeted population and were even often excluded from the trials.
Pouchitis becomes a chronic problem with a huge impact in the quality of life of these patients. The incidence of pouchitis has been rising in the last decades. This increase might be explained by a change in dietary habits of this population.
This open label single center trial at UZ Leuven aims to evaluate the efficacy and safety of guselkumab in the treatment of chronic antibiotic refractory pouchitis during a 48-week treatment period, with or without a dietary intervention. Twenty subjects with a proctocolectomy and IPAA for UC who have developed chronic or relapsing pouchitis will be enrolled.

Elucidating Shared Mechanisms Contributing to Non-Alcoholic Fatty Liver Disease (NAFLD) and Psoriatic Arthritis (PsA) Disease Severity With Guselkumab Therapy

While many studies examine Nonalcoholic fatty liver disease (NAFLD), little is known about its progression to high-risk nonalcoholic steatohepatitis (NASH) in PsA patients. Shared disease mechanisms may explain the increased severity in PsA. This study involves two visits from PsA patients with NAFLD and active disease signs (e.g., swollen joint, enthesitis, or psoriatic plaque). It aims to assess the impact of biological therapies on liver disorders, joints, and skin in PsA patients.

Efficacy of Guselkumab in the Treatment of Hailey Hailey Disease: An Open-label, Proof of Concept Study

Hailey-Hailey disease (HHD) is a debilitating genetic skin disorder, affecting mainly body folds with erythema and painful erosions and blisters. Histopathological findings include epidermal hyperplasia, suprabasilar clefting, dyskeratosis and acantholysis of keratinocytes. A final diagnosis of HHD is usually confirmed based on clinical and histopathological findings in line with genetic testing.
Several treatment options have been proposed for this chronic and disabling disorder, however, there is no reproducibly effective therapeutic for it.
The primary objective is to evaluate the treatment response of guselkumab. Single-center, non-randomized, single-arm, open-label, phase II trial to evaluate the efficacy and safety of guselkumab for the treatment of patients with HHD.

Residual non-specific and disease-specific inflammatory markers in successfully treated young psoriasis patients: a cross-sectional study

Article

Author: Kraner Šumenjak, Tadeja ; Merzel Šabović, Eva Klara ; Božič Mijovski, Mojca ; Janić, Miodrag

Abstract:

Psoriasis is a chronic, immune-mediated disease. The systemic inflammation triggered by psoriasis contributes significantly to increased cardiovascular risk. While various treatments completely clear the skin, the associated effects on systemic inflammation are not yet clear. We investigated residual systemic inflammation in successfully treated patients. Circulating disease-specific and non-specific inflammatory markers were measured and compared in 80 psoriasis patients (aged 30–45 years) successfully treated with topical therapy, methotrexate, adalimumab, secukinumab or guselkumab, and in 20 healthy controls. Non-specific inflammatory markers (high-sensitivity C-reactive protein (hs-CRP), complete blood count (CBC) parameters, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), mean platelet volume-to-platelet ratio (MPR), and red blood cell distribution width-to-platelet ratio (RPR)) and disease-specific inflammatory markers (interferon-γ (IFN-γ), tumor necrosis factor (TNF), interleukin (IL)-1β, IL-12p70, IL-17, and IL-23) were measured and compared between groups. Disease-specific cytokines (IFN-γ, TNF, IL-1β, IL-12p70, and IL-17, but not IL-23), were significantly elevated in patients compared to controls, while non-specific inflammatory markers showed no differences compared to controls. The residual disease-specific cytokines were similarly elevated in all five treated groups. In addition, they correlated significantly with body mass index (BMI) and waist circumference. Our results suggest that psoriasis patients have elevated residual disease-specific cytokines despite successful treatment, while the non-specific inflammatory markers are similar to those in control subjects. Residual disease-specific inflammatory markers correlated with BMI and waist circumference. A possible beneficial effect of body weight control in psoriasis patients merits further investigation. The study was registered at http://clinicaltrials.gov (identifier: NCT05957120) on July 24, 2023.

Author: Eghbali, Sara ; Ghane, Yekta ; Lotfi, Zahra ; Heidari, Nazila ; Hajikarim-Hamedani, Arman ; Heidari, Amirhossein ; Pishraft-Sabet, Homayoun ; Goodarzi, Azadeh

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disorder that presents significant treatment challenges. Recent advancements have enhanced our understanding of its pathophysiology, leading to the development of novel therapeutic strategies. This systematic review evaluates the role of interleukin (IL) inhibitors as emerging treatment options for HS. A systematic search was conducted in PubMed/Medline, Scopus, and Web of Science databases for studies published up to September 2nd, 2024, with inclusion limited to clinical trials available in English. The National Institute of Health (NIH) Quality Assessment Tool for clinical trials and before-after studies with no control group was used to assess the methodological quality of the included studies. Out of 1289 studies, 20 met our inclusion criteria involving 3957 patients. Secukinumab showed sustained hidradenitis Suppurativa Clinical Response (HiSCR) improvements, particularly in biologic-naïve patients with common adverse events (AEs). Bimekizumab was effective with biweekly dosing, while the four-week regimen had inconsistent results, with rare reports of AEs. Brodalumab and bermekimab provided rapid and sustained HiSCR responses with lesion reductions, which were well tolerated. Guselkumab and ustekinumab showed promising but statistically nonsignificant improvements with mild AEs. Risankizumab did not significantly improve HiSCR rates but showed Dermatology Life Quality Index (DLQI) benefits. Anakinra offered moderate efficacy with prolonged exacerbation-free periods but led to some treatment discontinuations. Spesolimab reduced inflammatory lesions and draining tunnels while maintaining a favorable safety profile. IL inhibitors, especially IL-17 inhibitors, have demonstrated efficacy in treating moderate-to-severe HS, while IL-23 inhibitors have shown inconsistent results. Despite their generally favorable safety profiles, further research is needed to optimize treatment strategies and assess long-term outcomes.

Diffusion dimensionality modeling of subcutaneous/intramuscular absorption of antibodies and long-acting injectables

Article

Author: Ramanathan, Murali ; Krzyzanski, Wojciech

To evaluate the role of diffusion process dimensionality in drug absorption following subcutaneous or intramuscular administration. The diffusion dimensionality model is based on analytical solutions of the 1-, 2- or 3-dimensional diffusion equations for a bolus input linked to a central compartment with first-order elimination. The model equations were reparameterized to contain three parameters for the time needed for the drug diffusion from the administration site, drug absorption into the central compartment, and the elimination rate constant. The diffusion dimensionality models were challenged with previously published subcutaneous absorption data for 13 antibody drugs and insulin lispro, and the long-acting injectable antipsychotic drugs: subcutaneous Perseris™, intramuscular Invega Sustenna®, Risperdal Consta®, and olanzapine. The Bayesian information criterion was used for model selection. The solution to the diffusion equation for a bolus dose administration is strongly dependent on the number of dimensions. The maximal concentration is lowest for the 3-dimensional diffusion equation. The pharmacokinetic profiles of all 13 antibodies were satisfactorily approximated by a diffusion dimensionality model. Three antibodies (CNTO5825, ACE910 and ustekinumab) were best described by the 2-dimensional diffusion equation. The 2- and 3-dimensional diffusion equations were equivalent for ABT981, guselkumab, adalimumab, nemolizumab, omalizumab, and secukinumab. Golimumab, DX2930, AMG139, and mepolizumab were best described by the 3-dimensional diffusion equation. All the long-acting antipsychotic dosage forms except Risperdal Consta were modeled satisfactorily. Diffusion dimensionality models are a parsimonious and effective approach for modeling drug absorption profiles of subcutaneously and intramuscularly administered small molecule and protein drugs and their dosage forms.

TREMFYA® (guselkumab) positioned to become the first and only IL-23 inhibitor to offer subcutaneous induction in ulcerative colitis as demonstrated in new data through 24 weeks

TREMFYA® subcutaneous induction demonstrates significant rates of clinical remission and endoscopic improvement at Week 24 in ulcerative colitis Findings build on recent FDA-approval of both routes of administration for induction therapy with TREMFYA® in Crohn's disease SAN DIEGO, May 5, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced new data from the Phase 3 ASTRO study evaluating TREMFYA® (guselkumab) subcutaneous (SC) induction therapy in adults with moderately to severely active ulcerative colitis (UC). The ASTRO Week 24 data build on the Week 12 SC induction data that showed statistically significant and clinically meaningful improvements compared to placebo across all clinical and endoscopic measures consistent with the U.S. Food and Drug Administration (FDA)-approved intravenous (IV) induction regimen evaluated in this population, in the Phase 3 QUASAR study.1,2 TREMFYA® is the first and only IL-23 inhibitor to demonstrate robust results with a fully SC regimen. These findings are among 24 abstracts highlighting the Company's research being presented at Digestive Disease Week (DDW) 2025. Data at Week 24 show patients treated with TREMFYA® 400 mg SC induction followed by SC maintenance dose regimens of either 100 mg every eight weeks (q8w) or 200 mg every four weeks (q4w) demonstrated statistically significant and clinically meaningful improvements across all clinical and endoscopic measures compared with patients receiving placebo.1 "Data from the ASTRO study demonstrate that subcutaneous induction treatment with TREMFYA provides clinically meaningful remission in patients with ulcerative colitis, similar to the effects seen with intravenous induction," said Millie Long, M.D., MPH, Professor of Gastroenterology and Hepatology at the University of North Carolina at Chapel Hill and study investigator.e "The availability of both subcutaneous and intravenous induction options would offer physicians and patients greater flexibility in their treatment approach." Furthermore, at Week 24, in prespecified analyses of subpopulations defined by prior advanced therapy treatment status, TREMFYA® demonstrated statistically significant results across endpoints in both biologic and JAK inhibitor-naïve and biologic and JAK inhibitor-refractory patients. Safety data from the ASTRO study were consistent with the well-established safety profile of TREMFYA®.1 "These results highlight the potential of TREMFYA to redefine ulcerative colitis care with a fully subcutaneous induction and maintenance regimen that offers a convenient option with meaningful clinical and endoscopic improvements," said Esi Lamousé-Smith, MD, PhD, Vice President, Gastroenterology Disease Area Lead, Immunology, Johnson & Johnson Innovative Medicine. "Our goal is to reshape UC care and empower prescribers with a differentiated and effective treatment that offers the option of patient self-administration from day one." TREMFYA® is the first and only approved, dual-acting monoclonal antibody that blocks IL-23 while also binding to CD64, a receptor on cells that produce IL-23. IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including UC.3,4,5,6,7 TREMFYA® received FDA approval in September 2024 for the treatment of adult patients with moderately to severely active UC and is currently administered via an IV induction regimen, followed by a SC maintenance regimen. In November 2024, a supplemental Biologics License Application (sBLA) was submitted to the FDA seeking approval of a SC induction regimen of TREMFYA® for the treatment of adults with moderately to severely active UC. TREMFYA® was also approved by the FDA in March 2025 for SC and IV induction options for the treatment of adults with moderately to severely active Crohn's disease (CD). For a full list of all data being presented at DDW visit: Editor's Notes: a. Clinical remission was defined as a Mayo stool frequency subscore of 0 or 1 and not increased from baseline, a Mayo rectal bleeding subscore of 0, and a Mayo endoscopic subscore of 0, or 1 with no friability present on the endoscopy. b. Symptomatic remission per Mayo score is defined as a stool frequency subscore of 0 (normal number of stools) or 1 (1 to 2 stools more than normal) and a rectal bleeding subscore of 0 (no blood seen). c. Endoscopic improvement was defined as an endoscopy subscore of 0 or 1 with no friability present on the endoscopy. d. Clinical response is defined as decrease from baseline in the modified Mayo score by greater than or equal to (>=) 30 percent (%) and >=2 points, with either a >=1-point decrease from baseline in the rectal bleeding subscore or a rectal bleeding subscore of 0 or 1. e.

ABOUT THE ASTRO STUDY (NCT05528510) ASTRO is a randomized, double-blind, placebo-controlled, parallel-group, multicenter, treat-through Phase 3 study designed to evaluate the efficacy and safety of TREMFYA® SC induction therapy (400 mg at Weeks 0, 4, and 8) in adults with moderately to severely active ulcerative colitis who had an inadequate response or intolerance to conventional therapy (e.g., thiopurines or corticosteroids), prior biologics (TNF antagonists or vedolizumab) and/or ozanimod or approved JAK inhibitors. Patients (n = 418) were randomized 1:1:1 to receive TREMFYA® 400 mg SC induction at Weeks 0, 4 and 8 followed by TREMFYA® 200 mg SC every 4 weeks (q4w); or TREMFYA® 400 mg SC induction at Weeks 0, 4 and 8, followed by TREMFYA® 100 mg SC every 8 weeks (q8w); or placebo. The maintenance dose regimens in ASTRO (200 mg SC q4w and 100 mg SC q8w) are the same as those evaluated in the Phase 3 QUASAR program which established the efficacy and safety profile of IV induction followed by SC maintenance therapy in patients with moderate to severely active UC.8 ABOUT ULCERATIVE COLITIS Ulcerative colitis (UC) is a chronic disease of the large intestine, also known as the colon, in which the lining of the colon becomes inflamed and develops tiny open sores, or ulcers, that produce pus and mucus. It is the result of the immune system's overactive response. Symptoms vary but may typically include loose and more urgent bowel movements, rectal bleeding or bloody stool, persistent diarrhea, abdominal pain, loss of appetite, weight loss, and fatigue.9 ABOUT TREMFYA® (guselkumab) Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human, dual-acting monoclonal antibody designed to neutralize inflammation at the cellular source by blocking IL-23 and binding to CD64 (a receptor on cells that produce IL-23). Findings for dual-acting are limited to in vitro studies that demonstrate guselkumab binds to CD64, which is expressed on the surface of IL-23 producing cells in an inflammatory monocyte model. The clinical significance of this finding is not known.

J&J’s Tremfya gains EC marketing authorisation for ulcerative colitis

Ulcerative colitis is a chronic inflammatory condition of the colon. Credit: Jo Panuwat D/Shutterstock. The European Commission (EC) has granted marketing authorisation for Johnson & Johnson’s (J&J) Tremfya (guselkumab) to treat adults with moderately to severely active ulcerative colitis (UC) who have not responded adequately to conventional therapy or biologic treatment. UC is a chronic inflammatory condition of the colon. Tremfya, developed by J&J, is the first fully-human, dual-acting interleukin-23 (IL-23) p19 subunit inhibitor that targets IL-23, a known driver of immune-mediated conditions, along with UC. The approval is underpinned by the QUASAR programme data, which includes a Phase IIb induction dose-ranging trial and Phase III induction and maintenance trials. These trials assessed guselkumab’s safety and efficacy in the target patient group. 45% of subjects on a 100mg subcutaneous dose every eight weeks and 50% on a 200mg dose every four weeks achieved clinical remission at week 44, higher than the 19% remission rate in placebo-treated subjects.

By GlobalData Learn more about Strategic Intelligence In addition, 35% of patients on the 100mg dose and 34% on the 200mg dose attained endoscopic normalisation at week 44, versus 15% for placebo. The safety profile of the therapy in UC aligns with its established safety record in psoriasis and psoriatic arthritis indications. J&J innovative medicine EMEA [Europe, Middle East and Africa] immunology therapeutic area lead and senior director Mark Graham stated: “There is a significant need for new ulcerative colitis therapies that offer meaningful improvements in symptoms and the promise of remission – both overall clinical remission and visible healing of the colon through endoscopic normalisation. “This approval builds on our sustained efforts to help improve the quality of life of patients, which can be significantly impacted from both a physical and mental health perspective.” For UC treatment, guselkumab is initially given as a 200mg intravenous induction dose at weeks zero, four and eight. The recommended maintenance dosage is 100mg administered subcutaneously at week 16, then every eight weeks. If patients do not respond adequately to the induction treatment, a 200mg subcutaneous maintenance dose every four weeks may be considered. This approval adds a third indication for the therapy in the EU. It was first approved there in November 2017 for moderate-to-severe plaque psoriasis and later for active psoriatic arthritis in November 2020. The EC is also reviewing an expansion of guselkumab’s marketing authorisation to include treatment for moderately to severely active Crohn’s disease, with a decision expected later in 2025. In early April 2025, the EC approved an extended indication for Janssen-Cilag International’s Darzalex (daratumumab) subcutaneous formulation for newly diagnosed multiple myeloma in adults.
