Tulisokibart is now being evaluated in two Phase 3 studies in ulcerative colitis and Crohn’s disease
12-week data from the Phase 2 ARTEMIS-UC trial recently published in the New England Journal of Medicine
RAHWAY, N.J.--(BUSINESS WIRE)--Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced that new data highlighting the long-term efficacy and safety of tulisokibart (MK-7240), an investigational humanized monoclonal antibody directed to a novel target, tumor necrosis factor (TNF)-like cytokine 1A (TL1A), in ulcerative colitis (UC) and Crohn’s disease (CD) will be presented at the United European Gastroenterology (UEG) Week 2024 Congress in Vienna, Austria.
Long-term efficacy and safety data for tulisokibart from the open-label extension period of the Phase 2 ARTEMIS-UC and APOLLO-CD studies will be featured in two oral presentations. In both studies, at week 50, maintenance of treatment efficacy was generally observed in 12-week induction responders. The observed safety profile in the study extensions was consistent with previously reported data. Key data presentation details:
- #OP078: Long-term efficacy and safety of tulisokibart in patients with Crohn’s disease (CD): Results from the open-label extension period of the Phase 2 APOLLO-CD study; October 14, 10:12-10:24 a.m. CEST
- #OP194: Long-term efficacy and safety of tulisokibart in patients with ulcerative colitis (UC): Results from the open-label extension period of the Phase 2 ARTEMIS-UC study; October 15, 11:54-12:06 p.m. CEST
“We are encouraged by the new maintenance data for tulisokibart in ulcerative colitis and Crohn’s disease, which shows the potential of this novel approach to help patients achieve long-term clinical remission,” said Dr. Aileen Pangan, vice president, global clinical development, Merck Research Laboratories. “Many patients with inflammatory bowel disease do not achieve their treatment goals despite available therapies. There is still a need for additional treatment options to enable patients to manage the challenging symptoms of ulcerative colitis and Crohn’s disease.”
Merck has initiated two Phase 3 studies to evaluate the efficacy and safety of tulisokibart in patients with UC (ATLAS-UC; NCT06052059) and CD (ARES-CD; NCT06430801). These are the first Phase 3 clinical studies for an anti-TL1A antibody in inflammatory bowel disease.
Additionally, results from ARTEMIS-UC, a Phase 2 proof-of-concept study evaluating the efficacy and safety of tulisokibart in patients with moderately to severely active UC were recently published in the New England Journal of Medicine. These data were first presented at the 18th Congress of European Crohn’s and Colitis Organisation (ECCO) in 2023. Findings published in the New England Journal of Medicine show that after 12 weeks, tulisokibart was more effective than placebo for inducing clinical remission in patients with moderately to severely active UC. The publication also includes additional data from a prespecified analysis of patients with a positive test for likelihood of response from cohorts 1 and 2.
About Ulcerative Colitis
Ulcerative colitis (UC) is a chronic disease of the large intestine that causes chronic inflammation and ulcers in the lining of the large intestine and rectum. Symptoms of UC include diarrhea, rectal bleeding, abdominal pain, rectal urgency and weight loss, with some patients also developing complications such as strictures. The severity of symptoms places a substantial burden on the more than five million people living with UC worldwide.
About Crohn’s Disease
Crohn’s disease (CD) causes chronic inflammation which can affect all parts of the gastrointestinal tract from mouth to anus. Symptoms of CD include abdominal pain, diarrhea with or without bleeding and weight loss. These symptoms, along with complications such as fistulas and strictures, can cause significant physical burden on the estimated six to eight million people living with CD worldwide.
About Tulisokibart
Tulisokibart is an investigational humanized monoclonal antibody directed to a novel target, tumor necrosis factor (TNF)-like cytokine 1A (TL1A), that is associated with both intestinal inflammation and fibrosis. Tulisokibart is thought to bind both soluble and membrane-bound human TL1A. Clinical studies suggest that tulisokibart may inhibit inflammatory pathways involved in inflammatory bowel disease (IBD), and help reduce intestinal fibrosis, which may be important in altering disease progression in IBD. Merck is developing tulisokibart for the treatment of immune-mediated inflammatory diseases including ulcerative colitis, Crohn’s disease and systemic sclerosis-associated interstitial lung disease (SSc-ILD).
