Crohn Disease

Data from the QUASAR long-term extension study demonstrate more than 70% of patients were in clinical remission and more than 40% of patients were in endoscopic remission at Week 92 SAN DIEGO, Calif., May 5, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) today announced new data from the TREMFYA® (guselkumab) Phase 3 QUASAR long-term extension (LTE) study in adults with moderately-to-severely active ulcerative colitis (UC). These data are among 24 abstracts highlighting the Company's research being presented at Digestive Disease Week (DDW) 2025. Data from the QUASAR LTE study demonstrate patients treated with TREMFYA® sustained clinical and endoscopic efficacy at Week 92: a, 1 72% of patients were in clinical remissionb with 99% of those patients remaining corticosteroid free for 8 or more weeks through Week 92. 43% of patients were in endoscopic remission.c Among patients achieving endoscopic improvementd at Week 44, 84% maintained endoscopic improvement through Week 92. Patients treated with TREMFYA® sustained clinical and endoscopic remission regardless of prior biologic and/or JAK inhibitor treatment history. "People living with ulcerative colitis seek treatments that both address the challenging symptoms of the disease and provide durable results," said Gary R. Lichtenstein, Vice Chief, Division of Gastroenterology and Hepatology, Development and Philanthropy at the University of Pennsylvania.e "These new data show TREMFYA delivers long-term, sustained clinical and endoscopic remission, marking important progress in UC care." Safety data were consistent with the well-established safety profile of TREMFYA® in inflammatory bowel disease (IBD) with no new safety concerns identified. "With these findings, TREMFYA shows the powerful impact it can have in achieving longer term remission in patients," said Esi Lamousé-Smith, MD, PhD, Vice President, Gastroenterology Disease Area Lead, Immunology, Johnson & Johnson Innovative Medicine. "This is a significant step forward in our mission to reshape the standard of care in inflammatory bowel disease." 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.2,3,4,5,6 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. Nonresponder imputation results. Data were analyzed using 2 methods: 'nonresponder imputation' (NRI) accounting for patients with treatment failure or missing data, and 'as observed'. NRI results were consistent with as observed. b. Clinical remission was defined as a Mayo stool frequency subscore of 0 or 1 and not increased from induction baseline, a Mayo rectal bleeding subscore of 0, and a Mayo endoscopic subscore (MES) of 0 or 1. c. Endoscopic remission (normalization) was defined as a MES of 0. d. Endoscopic improvement was defined as a MES of 0 or 1. e. Dr. Lichtenstein has received honorarium for his role as a consultant to Johnson & Johnson. He has not been compensated for any media work. ABOUT THE QUASAR PROGRAM (NCT04033445) QUASAR is a randomized, double-blind, placebo-controlled, parallel group, multicenter, Phase 2b/3 program designed to evaluate the efficacy and safety of TREMFYA® 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 JAK inhibitors (tofacitinib). QUASAR included a Phase 2b dose-ranging induction study, a confirmatory Phase 3 induction study, and a Phase 3 randomized withdrawal maintenance study. In the Phase 3 induction study, patients received either TREMFYA® 200 mg or placebo by IV infusion at Weeks 0, 4, and 8. In the Phase 3 maintenance study, patients received a SC maintenance regimen of either TREMFYA® 200 mg q4w, TREMFYA® 100 mg q8w, or placebo.7 The ongoing long-term extension study provides an additional 4 years of treatment. Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points. 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.8 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.

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.

SPY001 is a novel, half-life extended α4β7 antibody in development for the treatment of Inflammatory Bowel Disease (IBD) SPY001 pharmacokinetic (PK) data up to eight months continues to support a potential best-in-class profile, including a half-life more than three times that of vedolizumab SPY001 pharmacodynamic (PD) data up to eight months showed that a single dose of SPY001 resulted in rapid and sustained saturation of α4β7 receptors at expected Phase 2 trough concentrations Spyre remains on track to initiate its planned platform Phase 2 trial in mid-2025 that includes SPY001, followed by SPY002 (TL1A), SPY003 (IL-23), and combinations thereof, with initial monotherapy data expected in 2026 WALTHAM, Mass., May 5, 2025 /PRNewswire/ -- Spyre Therapeutics, Inc. (NASDAQ: SYRE) (the "Company" or "Spyre"), a clinical-stage biotechnology company advancing best-in-class antibody engineering, dose optimization, and rational therapeutic combinations for the treatment of Inflammatory Bowel Disease ("IBD") and other immune-mediated diseases, today announced two poster presentations at Digestive Disease Week (DDW) 2025, being held May 3-6, 2025, in San Diego, California. Spyre presented results out to eight months of follow up from its SPY001 Phase 1 program. Updated results from our ongoing Phase 1 trial of SPY001, our novel half-life extended α4β7 antibody for the treatment of IBD, continues to show that SPY001 is well tolerated, has a half-life of more than three-fold compared to vedolizumab based on population PK modeling, and sustains target engagement at expected Phase 2 trough concentrations. This longer follow-up data strengthens the potential for SPY001 to demonstrate improved induction responses with greater exposures as well as durable responses with quarterly or biannual maintenance dosing. Spyre presented expanded preclinical data on combined inhibition of α4β7 integrin and TL1A cytokine in murine colitis models. Data presented demonstrate that combined inhibition of α4β7 integrin and TL1A cytokine is superior to either monotherapy in mouse models of colitis. "Extended follow-up data continue to show that SPY001 is well tolerated and has a PK and PD profile that supports potential best-in-class quarterly or biannual dosing for patients with IBD," said Deanna Nguyen, MD, SVP of Clinical Development at Spyre. "We look forward to testing SPY001 as a monotherapy and as a backbone for combinations in our Phase 2 platform trial in ulcerative colitis patients, which remains on-track to begin mid-year." The poster will be available for viewing during the DDW exhibition, and details are as follows: Title: Interim PK Data for SPY001, a Novel Half-Life Extended Monoclonal Antibody Targeting α4β7, Suggest a Potential for Q3M or Q6M Maintenance Dosing for Inflammatory Bowel Disease Authors: D Nguyen, L Yan, K Hew, P Patel, R McLean, R Himes, T Das, M Huyghe, B Connolly, J Friedman Title: Combined inhibition of TL1A and integrin β7 is superior to either monotherapy in mouse models of colitis and coadministration of SPY001 and SPY002 demonstrates no drug-drug effects on exposure in non-human primates Authors: M Siegel, J Friedman, D Nguyen, J McNally, M Kennedy, O Ballew, M Rose, A Spencer Full session details can be accessed via the DDW Program. About SPY001 SPY001 is an investigational novel, extended half-life monoclonal antibody targeting α4β7 for the treatment of IBD. IBD is a chronic condition characterized by inflammation in the gastrointestinal tract and encompasses two main disorders: ulcerative colitis and Crohn's disease. In the United States, it is estimated that approximately 2.4 million individuals currently have IBD. SPY001 targets the same epitope as vedolizumab and demonstrates equivalent potency and selectivity as vedolizumab in head-to-head preclinical studies. Interim data from a Phase 1 trial demonstrated that SPY001 was well tolerated and exhibited a human half-life of ~80 days, approximately three-fold greater than vedolizumab. This half-life supports potential quarterly or biannual SC maintenance dosing in a single autoinjector compared to vedolizumab's Q2W SC profile. Based on initial Phase 1 clinical data, the company plans to initiate a Phase 2 platform trial in ulcerative colitis in mid-2025.
