TREMFYA® (guselkumab) QUASAR Maintenance Study in UC met its primary endpoint and all major secondary endpoints, including highly statistically significant rates of endoscopic remission
Clinical ResultDrug ApprovalPhase 3Phase 2
WASHINGTON, May 20, 2024 /PRNewswire/ -- Johnson & Johnson today announced the first data from the Phase 3 QUASAR Maintenance Study (Abstract #759) that showed 50.0 percent (pa (UC) receiving subcutaneous (SC) TREMFYA® (guselkumab) 200 mg every four weeks (q4w) and 45.2 percent (p® 100 mg every eight weeks (q8w) achieved the primary endpoint of clinical remissionb at Week 44 compared to placebo (18.9 percent).1 In additional analyses of patients who were in clinical remission, 67 percent and 71 percent, respectively, were also in endoscopic remission at Week 44 (Mayo endoscopic subscore [MES]= 0), indicating they had normal appearance of intestinal mucosa.2
"These data suggest the potential of guselkumab to provide durable, clinical remission and improve important high-bar endpoints such as endoscopic remission to the point of normalization and histologic remission, which represent the kind of progress needed in new treatments for this inflammatory bowel disease," said David T. Rubin, M.D., Chief, Section of Gastroenterology, Hepatology and Nutrition, University of Chicago and lead study investigator.f "The clinical results measured at Week 44 in the QUASAR Maintenance Study suggest that treatment with guselkumab is a promising therapy to help ulcerative colitis patients with challenging symptoms that impact their daily lives."
Both TREMFYA® treatment groups also met all nine major secondary endpoints with high statistical significance and clinically meaningful improvements versus placebo. A summary of select secondary endpoints from the 44-week Maintenance Study include:1
The proportion of patients with more than one adverse event (AE) was similar across treatment groups: SC TREMFYA® 200mg q4w, 70.0 percent; SC TREMFYA® 100mg q8w, 64.5 percent; placebo, 68.2 percent.1 The most common AEs in the combined TREMFYA® group compared to placebo were COVID-19 (11.2 percent vs. 14.1 percent), UC (11.2 percent vs. 29.7 percent) and joint pain (6.1 percent vs. 6.8 percent), respectively.1 The safety results were consistent to the safety profile of TREMFYA® in the approved indications of moderate to severe plaque psoriasis (PsO) and active psoriatic arthritis (PsA).1,e
"The Phase 3 QUASAR Maintenance Study continues to demonstrate the promise of TREMFYA to unlock potential treatment options for patients living with ulcerative colitis who continue to experience debilitating symptoms despite the availability of treatments today," said David Lee, M.D., Ph.D., Global Therapeutic Area Head, Immunology, Johnson & Johnson. "These findings underscore our commitment to elevate the standard of care in ulcerative colitis and strengthen our resolve to advance inflammatory bowel disease science."
These data are among 28 oral and poster presentations that Johnson & Johnson is presenting at Digestive Disease Week 2024, highlighting the company's commitment and leadership in advancing the science of inflammatory bowel disease.
This year, Johnson & Johnson submitted regulatory applications seeking the approval of TREMFYA® for the treatment of adults with moderately to severely active UC in countries or regions including the United States and Europe.
Editor's Notes:
a. Baseline modified score of 5 to 9 with a Mayo rectal bleeding subscore of ≥ 1 and a Mayo endoscopy subscore ≥ 2 based on central review.1
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 endoscopy subscore of 0 or 1 with no friability present on the endoscopy.1
c. Endoscopic remission (normalization) was defined as a MES of 0.1
d. Histologic-endoscopic mucosal improvement was defined as achieving a combination of histologic improvement (neutrophil infiltration in 1
e. TREMFYA® is not approved for the treatment of adults living with UC in the U.S.

g. Endoscopic improvement was defined as an endoscopy subscore of 0 or 1 with no friability present on the endoscopy.1
h. Clinical response was defined as a decrease from induction baseline in the modified Mayo score by ≥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 1.1
ABOUT THE
QUASAR PROGRAM (NCT04033445)
QUASAR is a randomized, double-blind, placebo-controlled, parallel group, multicenter, seamless Phase 2b/3 program designed to evaluate the efficacy and safety of guselkumab, a selective IL-23 inhibitorIL-23 inhibitor, in adult patients with moderately to severely active ulcerative colitis who experienced an inadequate response or who demonstrate intolerance to conventional therapy (e.g., thiopurines or corticosteroids), other biologics and/or JAK inhibitorsJAK inhibitors (i.e., tumor necrosis factor [TNF]-alpha antagoniststumor necrosis factor [TNF]-alpha antagonists, vedolizumab, or tofacitinib).3 QUASAR includes a Phase 2b dose-ranging induction study, a confirmatory Phase 3 induction study, a Phase 3 randomized withdrawal maintenance study, and a long-term extension study through a total of 5 years. Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points.2
In the Phase 3 randomized withdrawal QUASAR Maintenance Study, adult patients who demonstrated a clinical response to 12 weeks of TREMFYA® IV induction in the Phase 2 and Phase 3 induction studies were randomized 1:1:1 to three treatment groups: SC TREMFYA® 200 mg q4w, TREMFYA® 100 mg q8w or placebo (TREMFYA® withdrawal).1 The major secondary endpoints included corticosteroid-free clinical remission, maintenance of clinical remission, clinical response, symptomatic remission, endoscopic improvement, histo-endoscopic mucosal improvement, endoscopic normalization, Inflammatory Bowel Disease Questionnaire (IBDQ) remission, and fatigue response at Week 44 (56 weeks after initiation of treatment).1
ABOUT ULCERATIVE COLITIS
Ulcerative colitis 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.4 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. UC patients also have increased rates of depression.3
ABOUT
Developed by Johnson & Johnson, TREMFYA® is the first approved fully-human dual-acting monoclonal antibody that blocks IL-23 by binding to the p19 subunit of IL-23 and binding to CD64, a receptor on cells that produce IL-235. IL-23 is an important driver of the pathogenesis of inflammatory diseases.4 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.6,7,8,9
TREMFYA® is approved in the U.S. and a number of other countries 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.4,10 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.11
