Submission included data from the Phase 3 QUASAR program in ulcerative colitis and the Phase 3 GALAXI program in Crohn’s disease, which each achieved their primary endpoints1,2

BEERSE, Belgium I May 1, 2024 I Janssen-Cilag International NV, a Johnson & Johnson company, today announced it has submitted applications to the European Medicines Agency (EMA) seeking to expand the Marketing Authorization Application for TREMFYA® (guselkumab) to include the treatment of adult patients with moderately to severely active ulcerative colitis and moderately to severely active Crohn’s disease.

The submission included data from the Phase 3 QUASAR program in ulcerative colitis and the Phase 3 GALAXI program in Crohn’s disease.1,2,3,4,5 In the Phase 3 QUASAR induction and maintenance studies, guselkumab achieved each primary endpoint and showed statistically significant and clinically meaningful improvements relative to placebo in symptoms, measures of disease activity including stringent endpoints such as endoscopic normalization and histo-endoscopic mucosal healing, and patient-reported outcomes such as fatigue.1,3,4 The safety results were consistent with the known safety profile of guselkumab in approved indications.3,4,a

In the Phase 3 GALAXI 2 and 3 studies, guselkumab achieved co-primary endpoints at Week 12 and demonstrated statistically significant and clinically meaningful improvements relative to placebo in corticosteroid free clinical remission and endoscopic response at Week 48.2,5 Safety results were consistent with the known safety profile of guselkumab in approved indications.2,5

“People living with chronic, immune-mediated disease such as ulcerative colitis and Crohn’s disease often spend a considerable amount of time cycling from one treatment to another in search of relief and sustained remission,” said David Lee, MD, PhD, Global Therapeutic Area Head Immunology. “This submission is an important step in our mission to develop novel, effective therapies for the millions of people worldwide living with ulcerative colitis and Crohn’s disease who are experiencing persistent and debilitating symptoms.”

Guselkumab 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.6 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 ulcerative colitis and Crohn’s disease.7 Guselkumab is approved in the European Union (EU) for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy and for the treatment of active psoriatic arthritis in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.6

“Inflammatory bowel disease, which includes ulcerative colitis and Crohn’s disease, affects as many as four million people in Europe annually,” said Ludovic de Beaucoudrey, PhD, Senior Director, Therapeutic Area Lead, Immunology, Janssen-Cilag Limited, a company of Johnson & Johnson. “We look forward to working closely with the EMA during review of these applications and are deeply committed to rapidly innovating for those patients who live with immune-mediated diseases like ulcerative colitis and Crohn’s disease where considerable needs remain.”

Clinical data from the Phase 3 QUASAR induction study through 12 weeks were presented at the 2023 Digestive Disease Week Annual Meeting and results from the Phase 3 QUASAR maintenance study through 44 weeks will be presented at an upcoming medical meeting.3 Clinical data from the long-term extension of the GALAXI Phase 2 study through three years were presented at United European Gastroenterology Week 2023 and results from the Phase 3 studies through 48 weeks will be presented at an upcoming medical meeting.5 In March 2024, Johnson & Johnson submitted a supplemental Biologics License Application to the U.S. Food and Drug Administration seeking approval of guselkumab for treatment of adults with moderately to severely active ulcerative colitis.

Editor’s Notes:

a.  Guselkumab is not approved to treat ulcerative colitis or Crohn’s disease.

ABOUT THE QUASAR PROGRAM (EudraCT 2018-004002-25)
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 inhibitor, in adult patients with moderately to severely active ulcerative colitis who had an inadequate response or intolerance to conventional therapy (e.g., thiopurines or corticosteroids), prior biologics and/or JAK inhibitors (i.e., tumor necrosis factor [TNF]-alpha antagonists, vedolizumab, or tofacitinib).1 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.1 Efficacy, safety, pharmacokinetics, immunogenicity, and biomarkers are assessed at specified time points.1

ABOUT THE GALAXI PROGRAM (EudraCT 2017-002195-13)
GALAXI is a randomized, double-blind, placebo-controlled, active-controlled (ustekinumab), global, multicenter Phase 2/3 program designed to evaluate the efficacy and safety of guselkumab in participants with moderately to severely active Crohn’s disease with inadequate response/intolerance to conventional therapies (immunomodulators, corticosteroids) and/or biologics (TNF antagonists, vedolizumab).GALAXI includes a Phase 2 dose-ranging study (GALAXI 1) and two independent, identically designed confirmatory Phase 3 studies (GALAXI 2 and 3).2 Each GALAXI study employed a treat-through design in which participants remained on the treatment to which they were initially randomized and includes a long-term extension study that will assess clinical, endoscopic, and safety outcomes with guselkumab through a total of five years.2

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.8 It is the result of the immune system’s overactive response.8 Symptoms vary, but may 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 CROHN’S DISEASE
Crohn’s disease is one of the two main forms of inflammatory bowel disease, which affects an estimated four million people across Europe.Crohn’s disease is a chronic inflammatory condition of the gastrointestinal tract with no known cause, but the disease is associated with abnormalities of the immune system that could be triggered by a genetic predisposition, diet, or other environmental factors.10 Symptoms of Crohn’s disease can vary, but often include abdominal pain and tenderness, frequent diarrhea, rectal bleeding, weight loss, and fever. There is currently no cure for Crohn’s disease.11

ABOUT TREMFYA® (guselkumab)
Developed by Johnson & Johnson, 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.6 IL-23 is an important driver of the pathogenesis of inflammatory diseases.7 

TREMFYA® is approved in the U.S., Canada, Japan, and a number of other countries for the treatment of adults with moderate to severe plaque psoriasis who are candidates for injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light) and for the treatment of adult patients with active psoriatic arthritis.12,13,14 It is also approved in the EU for the treatment of moderate to severe plaque psoriasis in adults who are candidates for systemic therapy and for the treatment of active psoriatic arthritis in adult patients who have had an inadequate response or who have been intolerant to a prior disease-modifying antirheumatic drug therapy.6
