A greater number of patients treated with subcutaneous guselkumab induction and maintenance vs placebo achieved clinical remission and endoscopic response at 48 weeks in the Phase 3 GRAVITI study1
Guselkumab shows potential to become the first IL-23 treatment to offer both a subcutaneous and intravenous induction regimen for patients living with Crohn’s disease1
High Wycombe, UK (29 October 2024) – Johnson & Johnson today announced results from the Phase 3 GRAVITI study of TREMFYA® (guselkumab), the first IL-23 inhibitor, demonstrating robust results in subcutaneous (SC) induction and maintenance therapy. The findings demonstrated significant clinical remission and endoscopic response at 48 weeks vs placebo in adults with moderately to severely active Crohn’s disease (CD).1 These results are among the 14 Johnson & Johnson abstracts presented at the American College of Gastroenterology (ACG) 2024, 25th – 30th October 2024.
“The results from the GRAVITI study indicate that guselkumab has the potential to make a positive difference for individuals with Crohn’s disease,” said Professor Ailsa Hart, Consultant Gastroenterologist and Director Inflammatory Bowel Disease Research, St Mark’s Hospital & Imperial College, London, UK. “Subcutaneous induction therapy with guselkumab could help people living with Crohn’s disease to actively manage their symptoms and provides choice and flexibility for them and healthcare providers.”
GRAVITI SC Induction Week 12 Results:
- More than half of patients treated with guselkumab (400 mg administered subcutaneously at Weeks 0, 4, and 8) achieved clinical remission versus those in the placebo group (56.1 percent versus 21.4 percent; p<0.001).1
- Endoscopic response was achieved in 41.3 percent of patients treated with guselkumab SC induction therapy versus 21.4 percent in the placebo group (p<0.001).1
- Greater improvements in clinical remission were seen as early as Week 4 with guselkumab compared with placebo, demonstrating rapid onset of action.2
GRAVITI SC Induction Week 48 Results:
- The number of patients achieving clinical remission was more than three times higher with both maintenance doses of guselkumab versus placebo at week 48 (60.0 percent for 100 mg SC every eight weeks (q8w) and 66.1 percent for 200 mg SC every four weeks (q4w) versus 17.1 percent in the placebo group; p<0.001).1
- Endoscopic response at week 48 was achieved in 44.3 percent and 51.3 percent of patients in the guselkumab 100 mg SC q8w group and 200 mg SC q4w group respectively, versus 6.8 percent in the placebo group (p<0.001).1
- Endoscopic remission was achieved in 30.4 percent and 38.3 percent of patients in the guselkumab 100 mg SC q8w group and 200 mg SC q4w group respectively, versus 6.0 percent in the placebo group.2
The co-primary endpoint of clinical remission and endoscopic response at week 12 and all multiplicity-controlled endpoints were met.1 Safety findings were consistent with the known safety profile of guselkumab in approved indications.1,a
“These results show that guselkumab could become the first IL-23 inhibitor to offer both subcutaneous and intravenous induction options,” stated Dr. John Fleming, Country Medical Director, UK at Johnson & Johnson Innovative Medicine. “The one-year results of this study suggest that subcutaneous induction with guselkumab is a promising approach to help people with Crohn’s disease manage their symptoms and achieve meaningful endoscopic improvements.”
Johnson & Johnson submitted a regulatory application seeking the approval of guselkumab for the treatment of adults with moderately to severely active Ulcerative Colitis (UC) and for the treatment of adults with moderately to severely active CD in the United Kingdom.
Editor’s Notes:
ABOUT THE GRAVITI PROGRAMME (EudraCT 2020-006165-11)
GRAVITI is a randomised, double-blind, placebo-controlled, global, multicentre 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 have had an inadequate response or failed to tolerate conventional therapy (i.e., corticosteroids or immunomodulators) or biologic therapy (TNF antagonists or vedolizumab).1,3 The maintenance doses in GRAVITI are the same as those evaluated in GALAXI (200 mg SC q4w and 100 mg SC q8w).1,4 The study employed a treat-through design, in which patients are randomised 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 randomised 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 PROGRAMME (EudraCT 2017-002195-13)
GALAXI is a randomised, double-blind, placebo-controlled, active-controlled (ustekinumab), global, multicentre Phase 2/3 programme 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).4,5 GALAXI includes a Phase 2 dose- ranging study (GALAXI 1) and two independent, identically designed confirmatory Phase 3 studies (GALAXI 2 and 3).4,5 Each GALAXI study employed a treat-through design in which participants remained on the treatment to which they were initially randomised and includes a long-term extension study that will assess clinical, endoscopic, and safety outcomes with guselkumab through a total of five years.4,5 Patients received guselkumab 200 mg intravenous induction at Weeks 0, 4 and 8 followed by guselkumab 200 mg subcutaneous maintenance every 4 weeks; or guselkumab 200 mg intravenous induction at Weeks 0, 4 and 8, followed by guselkumab 100 mg subcutaneous maintenance every 8 weeks; or a biologic active control; or placebo.4 Participants randomised to placebo were able to receive ustekinumab if clinical response was not met at Week 12.5 Of the 873 individuals pooled across the GALAXI 2 & 3 dataset, 456 (52 percent) had prior history of inadequate response to biologics, 365 (41.8 percent) were biologic-naïve and 52 (6 percent) were biologic experienced without documented inadequate response or intolerance.4
ABOUT CROHN’S DISEASE
Crohn’s disease is one of the two main forms of inflammatory bowel disease, which affects over 500,000 people across the UK.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.8 Currently no cure is available for Crohn’s disease.9
ABOUT GUSELKUMAB
Developed by Johnson & Johnson, Guselkumab is the first approved fully human 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-23.10,11 IL-23 is an important driver of the pathogenesis of inflammatory diseases.12
