- The two induction cohorts missed the co-primary endpoints of clinical remission and endoscopic response at Week 10
- In the maintenance phase, filgotinib 200mg once daily achieved the co-primary endpoints of clinical remission and endoscopic response at Week 58
- The safety findings were generally consistent with the known profile of filgotinib in rheumatoid arthritis (RA) and ulcerative colitis (UC)
- Galapagos decided not to submit a Marketing Authorization Application in Europe based on these topline data
- Galapagos remains fully committed to filgotinib, a JAK1 preferential inhibitor orally administered once daily, and its approved indications, RA and UC, and is on track to start a Phase 3 trial in axial spondyloarthritis (AxSpA) later this year
MECHELEN, Belgium I February 8, 2023 I Galapagos NV (Euronext & NASDAQ: GLPG) today announced the topline results from DIVERSITY, a global Phase 3 trial to evaluate the safety and efficacy of filgotinib, 100mg or 200mg once daily, during induction and maintenance treatment of biologic-naïve and biologic-experienced patients with moderate to severe Crohn’s disease (CD).
The co-primary endpoints at Week 10 and Week 58 were clinical remission per Patient Reported Outcome (PRO-2) and endoscopic response per Simple Endoscopic Score for Crohn’s Disease (SES-CD).
Induction Cohort A included biologic-naïve (54%) and biologic-experienced (46%) patients; induction Cohort B included biologic-experienced patients. In total, 33% of patients in Cohort A and 52% of patients in Cohort B had failed treatment with 3 or more biologic drugs.
Both induction cohorts of the study failed to meet the co-primary endpoints of clinical remission and endoscopic response for filgotinib, 100mg and 200mg once daily.
In the maintenance phase of the study, a statistically significant higher proportion of patients receiving filgotinib 200mg once daily achieved the co-primary endpoints of clinical remission (43.8% vs. 26.4%; p=0.0382) and endoscopic response (30.4% vs. 9.4%; p=0.0038) compared to placebo at Week 58.
The safety observations of the study were in line with the underlying disease and were consistent with the safety profile of filgotinib in previous studies across indications.
“While Crohn’s disease is a difficult-to-treat condition and a large proportion of patients enrolled in DIVERSITY had high disease activity and long-standing disease with prior exposure to multiple therapies, we are disappointed with the outcome of the induction studies. However, at the same time, we are encouraged by the confirmed safety profile and the clinical efficacy signs observed in the maintenance phase,” said Prof. Dr. Séverine Vermeire, Research Director of the Group Biomedical Sciences, University of Leuven and staff member at the Gastroenterology Department of the University Hospital Leuven, Belgium.
Daniele D’Ambrosio, MD, PhD, Therapeutic Area Head, Immunology, at Galapagos added: “As filgotinib demonstrated robust late-stage clinical data in UC1 and in earlier Phase 2 clinical studies in CD, we are very disappointed with this outcome. The current topline data do not support a Marketing Authorization Application in Europe, and we will analyze the full results to gain valuable insights to guide future research efforts. Galapagos remains fully committed to filgotinib and its approved indications of RA and UC, and we are on track to initiate a Phase 3 study in patients with AxSpA later this year. We are grateful to the patients and all medical professionals who participated in this trial.”
About Crohn’s disease
Crohn’s disease is an inflammatory bowel disease in which the balance of the intestinal immune system is disturbed causing a significant burden on people living with this disease. Crohn’s disease is considered to be a progressive disease and causes ulcerations that may affect any part of the digestive system from mouth to anus. The cause of the disease is unknown, with onset usually between the ages of 15 and 35. Patients suffer from abdominal pain, diarrhea (often bloody), vomiting, fever, and weight loss. Estimates suggest there could be up to 1.6 million people living with Crohn’s disease across Europe, with up to 78,000 new cases every year.2 Despite the availability of advanced therapies, insufficient control of inflammation and loss of response over time are still a big problem for many CD patients.3
About the filgotinib clinical development program in Crohn’s disease
DIVERSITY consisted of a combined (induction and maintenance), double-blind, placebo-controlled Phase 3 trial, enrolling 1,374 biologic-naive and biologic-experienced patients with moderately to severely active CD in 384 centers worldwide. The primary objectives of the trial were to evaluate the safety and efficacy of filgotinib 100mg or 200mg, once-daily oral treatment, versus placebo.
The co-primary endpoints at Week 10 and Week 58 were clinical remission per Patient Reported Outcome (PRO-2) and endoscopic response per Simple Endoscopic Score for Crohn’s Disease (SES-CD). Clinical remission measured by the Crohn’s Disease Activity Index (CDAI) was a key secondary endpoint in the induction and maintenance phase of the study. Additional secondary endpoints were clinical remission and endoscopic response (combined into a single endpoint on a patient level) at Week 10, clinical remission and endoscopic response (combined into a single endpoint on a patient level) at Weeks 10 and 58, sustained clinical remission and endoscopic response at Weeks 10 and 58, and 6-month corticosteroid-free clinical remission at Week 58.
The results from the previous studies, Phase 2 FITZROY and Phase 2b DIVERGENCE, contributed to the long-term evaluation of filgotinib in Crohn’s disease. Full results of the FITZROY study were reported in The Lancet.4 A long-term extension study including patients who participated in DIVERSITY is currently ongoing.

About filgotinib
Filgotinib is marketed as Jyseleca in Europe and Japan for the treatment of adults with moderate to severe active rheumatoid arthritis (RA) who have responded inadequately or are intolerant to one or more disease modifying anti-rheumatic drugs (DMARDs). Filgotinib is also marketed as Jyseleca in Europe and Japan for the treatment of adult patients with moderate to severe active ulcerative colitis (UC) who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a biologic agent. Jyseleca (filgotinib) 100mg and 200mg are registered in the above-mentioned territories.
The European Summary of Product Characteristics for filgotinib, which includes contraindications and special warnings and precautions, is available at www.ema.europa.eu. The Great Britain Summary of Product Characteristics for filgotinib can be found at www.medicines.org.uk/emc and the Northern Ireland Summary of Product Characteristics for filgotinib can be found at www.emcmedicines.com/en-GB/northernireland, respectively.
