TREMFYA (guselkumab) studies underscore its potential to be the only IL-23 inhibitor to offer both subcutaneous and intravenous induction

PRNewswire 20-Jun-2024 8:00 AM

TREMFYA^® Phase 3 Crohn's disease study achieves all primary and secondary endpoints

SPRING HOUSE, Pa., June 20, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE:JNJ) today announced positive topline results from the pivotal Phase 3 GRAVITI investigational study of TREMFYA^® (guselkumab) subcutaneous (SC) induction therapy in adult patients with moderately to severely active Crohn's disease.¹ The study met both co-primary endpoints, achieving statistically significant and clinically meaningful outcomes for clinical remission at Week 12 as well as endoscopic response at Week 12. All remaining multiplicity-controlled secondary endpoints at Week 12, Week 24 and Week 48 were statistically significant compared to placebo. GRAVITI adds to the robust results demonstrated in GALAXI 2 and GALAXI 3, the first-ever double-blind registrational head-to-head clinical trials to demonstrate superiority versus STELARA^® (ustekinumab) in key endoscopic endpoints in Crohn's disease, which together show the potential of TREMFYA^® to become the only IL-23 inhibitor to offer both SC or IV induction options.^3,4 Safety data from GRAVITI were consistent with the well-characterized safety profile of TREMFYA^® in its approved indications.^2,a

"The Phase 3 GRAVITI study showed promising results with SC induction and provides similar clinical benefit to what was seen with IV induction in the GALAXI studies," said David Lee, M.D., Ph.D., Global Therapeutic Area Head Immunology, Johnson & Johnson Innovative Medicine. "Having both SC and IV induction options provides choice and versatility for patients and providers. TREMFYA is poised to be the only IL-23 inhibitor to offer a full SC therapy for both induction and maintenance in Crohn's disease."

Results from the GRAVITI study are being prepared for presentation at upcoming medical meetings and will be shared with health authorities in planned submissions. A separate Johnson & Johnson study evaluating the efficacy and safety of TREMFYA^® SC induction therapy in ulcerative colitis is ongoing.  

Editor's Notes:

a.  TREMFYA^® is not approved for the treatment of ulcerative colitis or Crohn's disease.

ABOUT THE GRAVITI PROGRAM (NCT05197049)

GRAVITI is a randomized, double-blind, placebo-controlled Phase 3 study to evaluate guselkumab SC induction therapy (400 mg at Weeks 0, 4, and 8) in patients with moderately to severely active Crohn's disease who experienced an inadequate response or failed to tolerate conventional therapy (i.e., corticosteroids or immunomodulators) or biologic therapy (TNF antagonists or vedolizumab).¹ The maintenance doses in GRAVITI are the same as those evaluated in GALAXI (200 mg SC q4w and 100 mg SC q8w).¹ The study employed a treat-through design, in which patients are randomized to guselkumab at Week 0 and remain on that regimen throughout the study, regardless of clinical response status at the end of induction.¹ Participants randomized to placebo were able to receive guselkumab (400 mg SC q4w x3 ? 100 mg SC q8w) if rescue criteria were met at Week 16.¹

ABOUT THE GALAXI PROGRAM (NCT03466411)

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 (corticosteroids or immunomodulators) and/or biologics (TNF antagonists or vedolizumab).³ GALAXI includes a Phase 2 dose-ranging study (GALAXI 1) and two independent, identically designed confirmatory Phase 3 studies (GALAXI 2 and 3).³ 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. Participants randomized to placebo were able to receive ustekinumab if clinical response was not met at Week 12. ³

ABOUT CROHN'S DISEASE

Crohn's disease is one of the two main forms of inflammatory bowel disease, which affects an estimated three million Americans and an estimated four million people across Europe.^5,6 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.⁷ Symptoms of Crohn's disease can vary, but often include abdominal pain and tenderness, frequent diarrhea, rectal bleeding, weight loss, and fever. Currently no cure is available for Crohn's disease.⁸

ABOUT TREMFYA^® (guselkumab)

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-23.⁹ IL-23 is an important driver of the pathogenesis of inflammatory diseases.¹⁰ 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.^11,12,13,14

TREMFYA^® is approved in the U.S.,⁹ Canada,¹⁵ Japan¹⁶ and a number of other countries for the treatment of adults with moderate-to-severe plaque psoriasis (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 psoriatic arthritis (PsA).¹⁷ 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.¹⁷
