Results of Novel Clinical Study of Guselkumab and Golimumab Combination Therapy Show Adults with Moderately to Severely Active Ulcerative Colitis Maintained Higher Rates of Clinical, Histologic, and Endoscopic Remission at Week 38

The rate of clinical remission was 47.9 percent in patients who received combination induction therapy with guselkumab and golimumab compared with either treatment alone (31.0 percent and 20.8 percent, respectively) at 38 weeks¹

SPRING HOUSE, PA, USA I October 10, 2022 I The Janssen Pharmaceutical Companies of Johnson & Johnson today announced data from an ongoing analysis of a Phase 2a clinical trial showing adults with moderately to severely active ulcerative colitis (UC) who received 12 weeks of combination induction therapy with guselkumab and golimumab, followed by a transition to guselkumab alone for maintenance, achieved a clinical remission rate^a (based on the modified Mayo score [mMayo])^b at week 38 of 47.9 percent, a higher rate than induction and maintenance treatment with either guselkumab alone (31.0 percent) or golimumab alone (20.8 percent).^1,2 Patients had comparable rates of adverse events (AEs) across the treatment groups.¹ Guselkumab alone, or the combination of guselkumab and golimumab are under clinical investigation and not approved for the treatment of adults with UC in the U.S.

The VEGA study is the first randomized controlled trial to evaluate the efficacy and safety of combination therapy with an interleukin (IL)-23p19 subunit antagonist (guselkumab) and a tumor necrosis factor-alpha (TNFα) antagonist (golimumab) in UC.^3,4 Detailed results were presented today as an oral presentation (OP087) at the United European Gastroenterology (UEG) Week 2022 congress taking place in-person in Vienna, Austria and virtually from October 8-11.¹

“Exploring combinations of advanced therapies is an important step in continuing to innovate for the many patients living with ulcerative colitis,” said Bruce E. Sands, M.D., M.S., Chief of the Dr. Henry D. Janowitz Division of Gastroenterology at Mount Sinai, Professor of Medicine at the Icahn School of Medicine at Mount Sinai, and VEGA Steering Committee member.^c “These new data from the VEGA trial build upon and affirm our initial 12-week findings showing the potential clinical benefit of combining guselkumab and golimumab in treating adults with moderately to severely active ulcerative colitis.”

In the VEGA study, patients with moderately to severely active UC were randomized (1:1:1) to receive combination therapy with guselkumab and golimumab, guselkumab monotherapy, or golimumab monotherapy.¹ After endpoints were evaluated at week 12, patients in the monotherapy groups continued their initially assigned treatment, while patients randomized to the combination therapy group transitioned to guselkumab alone as a maintenance therapy.¹ Patients remained blinded and received their respective therapies through the final efficacy assessment at week 38. Clinical remission^a,d was assessed based on the modified Mayo score (mMayo),^b as well as the total Mayo score.^e Symptomatic remission,^f endoscopic improvement,^g endoscopic remission,^h histologic remission,ⁱ and composite histologic-endoscopic endpoints^g,i were also assessed at week 38 in an exploratory analysis.¹ Safety was evaluated through week 50 (16 weeks after the final dose of study intervention at week 34).¹

Patients who received combination therapy with guselkumab and golimumab followed by maintenance treatment with guselkumab achieved clinical remission^a (mMayo^b) at week 38 (47.9 percent [34/71]) versus 31.0 percent (22/71) and 20.8 percent (15/72) of patients who received guselkumab or golimumab alone, respectively (nominal p=<0.05).¹

Rates of clinical remission^d as defined by the total Mayo score^e at week 38 were similar to those based on the mMayo,^a,b with 43.7 percent (31/71) in the combination therapy followed by guselkumab group achieving this endpoint, compared to either the guselkumab or golimumab monotherapy groups, (31.0 percent [22/71] and 22.2 percent [16/72], respectively).¹ 

Also, patients receiving combination therapy followed by guselkumab had the following outcomes at week 38:¹

• Endoscopic improvement^g and the composite histologic-endoscopic endpoint^g,i were higher in patients who received combination therapy followed by treatment with guselkumab compared to patients who received guselkumab or golimumab alone.
• Endoscopic remission^h and histologic remissionⁱ were higher in patients who received combination therapy followed by treatment with guselkumab compared to patients who received golimumab alone.

Patients receiving combination therapy followed by maintenance treatment with guselkumab and patients receiving treatment only with guselkumab monotherapy achieved the same rate of symptomatic remission^f of 69 percent at week 38, which was greater than the golimumab monotherapy group of 59.7 percent.¹

Rates of AEs were comparable through week 50 of the study.¹ Respectively, the combination therapy followed by guselkumab, guselkumab alone, and golimumab alone groups had AE rates of 63.4, 64.8, and 76.4 percent and infection rates of 31.0, 23.9, and 31.9 percent.¹ All groups had the same serious AE rates of 5.6 percent and the same serious infection rates of 2.8 percent.¹ Overall, 13.1 percent of patients discontinued their treatment prior to the final dose of study intervention.¹

“The 38-week VEGA data suggest the potential that guselkumab and golimumab combination therapy has in patients with moderately to severely active ulcerative colitis for whom previous conventional treatments have inadequately managed their disease or improved their well-being,” said Jan Wehkamp, M.D., Ph.D., Vice President, Gastroenterology Disease Area Leader, Janssen Research & Development, LLC. “We thank the patients who participated in the VEGA study, as their contribution helps us get closer to our goal of developing therapies that will bring meaningful improvements to patients with ulcerative colitis.”

Janssen previously announced the 12-week data of patient outcomes from the VEGA study at the 17th Congress of the European Crohn’s and Colitis Organisation on February 19, 2022.²

Editor’s Notes:

a. Clinical remission (based on the mMayo) is defined as a stool frequency subscore of 0 or 1, where the stool frequency subscore has not increased from baseline, a rectal bleeding subscore of 0, and an endoscopy subscore of 0 or 1 with no friability present on endoscopy.¹

b. Modified Mayo score consists of three of the four components of the full Mayo score: stool frequency, rectal bleeding, and endoscopic score. The physician global assessment score is not included.⁵

c. Dr. Sands is a paid consultant for Janssen. He has not been compensated for any media work.

d. Clinical remission is defined as a Mayo score ≤2, with no individual subscore >1.¹

e. The total Mayo score is the sum of four subscores – stool frequency, rectal bleeding, physician’s global assessment, and endoscopy findings – that are scored from normal (0) to severe (3).³

f. Symptomatic remission is defined as Mayo stool frequency subscore of 0 or 1, where the stool frequency subscore has not increased from baseline, and a rectal bleeding subscore of 0.¹

g. Endoscopic improvement is defined as an endoscopy subscore of 0 or 1 with no friability present on the endoscopy.¹

h. Endoscopic remission is defined as an endoscopy subscore of 0.¹

i. Histologic remission is defined as absence of neutrophils from the mucosa (both lamina propria and epithelium), no crypt destruction, and no erosions, ulcerations or granulation tissue according to the Geboes grading system.¹

About VEGA (NCT03662542; EudraCT 2018-001510-15) 

VEGA was a randomized, double-blind, active-controlled, parallel group, global multicenter Phase 2a proof-of-concept study evaluating the efficacy and safety of combination induction therapy with guselkumab and golimumab, followed by a transition to guselkumab monotherapy for maintenance, in patients with moderately to severely active UC as defined by a Mayo score of 6 to 12 inclusive and an endoscopy subscore of 2 or greater as determined by central read.^3,4

Study participants were naïve to TNFα, IL-12/23, and IL-23p19 antagonists and had to be refractory or intolerant to conventional therapy (e.g. immunosuppressants and/or corticosteroids).¹ Participants were randomly assigned 1:1:1 to receive guselkumab monotherapy dosed at 200 milligrams (mg) intravenously (IV) at weeks 0, 4, and 8 followed by 100 mg every 8 weeks (q8w) subcutaneous (SC) (n=71); golimumab SC monotherapy dosed at 200 mg at week 0 followed by 100 mg SC at weeks 2, 6, and 10 followed by 100 mg every 4 weeks SC monotherapy (n=72); or a combination of 200 mg IV guselkumab plus 200 mg SC golimumab at week 0, 100 mg SC golimumab at weeks 2, 6, and 10, and 200 mg IV guselkumab at weeks 4 and 8 (n=71) followed by 100 mg guselkumab SC q8w thereafter.¹ After week 12, participants in the monotherapy groups continued their initially assigned treatment, while patients randomized to the combination group transitioned to guselkumab 100 mg SC q8w as a maintenance therapy.¹ The participants received their respective therapies through week 34 with final efficacy assessments at week 38.¹

The primary endpoint was clinical response at week 12, defined as a decrease from baseline in the Mayo score by 30 percent or more and 3 or more points, with either a decrease in rectal bleeding subscore of 1 or more or rectal bleeding subscore of 0 or 1. The trial’s major secondary endpoint was clinical remission at week 12, defined as Mayo score less than or equal to 2, with no individual subscore more than 1. No adjustments were made for multiple comparisons.^2,3 Other key endpoints evaluated at week 12 were clinical remission (based on components of the mMayo score), symptomatic remission, endoscopic improvement, endoscopic remission, histologic remission, composite histologic-endoscopic endpoints, and biomarker outcomes.¹

About Ulcerative Colitis

Inflammatory bowel disease (IBD), which includes Crohn’s disease and UC, affect as many as 1.6 million people in the United States.⁶ 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.⁷ It is the result of the immune system’s overactive response.⁷ Symptoms vary, but may include loose and more urgent bowel movements, persistent diarrhea, abdominal pain, bloody stool, loss of appetite, weight loss, and fatigue.⁸
