Meta-Analysis Using Real-World Data Evaluates Safety Profile of Entyvio® (vedolizumab) in Patients with Moderate to Severe Ulcerative Colitis or Crohn’s Disease

Takeda Pharmaceutical Company Limited today announced the presentation of real-world evidence from two analyses evaluating the safety profile of Entyvio® (vedolizumab), during the 25th United European Gastroenterology (UEG) Week in Barcelona, Spain (October 28-November 1). It includes a systematic review and meta-analysis of real-world safety outcomes reported for Entyvio in ulcerative colitis (UC) or Crohn’s disease (CD), as well as a database analysis of the real-world use of immunosuppressive (IM) therapy in people living with inflammatory bowel disease (IBD) who initiated Entyvio treatment in the U.S.
A systematic review and meta-analysis of real-world outcomes screening 218 published studies from MEDLINE-, Cochrane-, and EMBASE-indexed publications and conference abstracts from May 1, 2014-January 10, 2017 examined safety events reported after use of Entyvio in patients with UC or CD. A total of 33 studies reported data on 2,857 Entyvio-treated patients (CD: 1,532; UC: 829) over an Entyvio exposure/follow-up period ranging 0.5-18 months. In the meta-analysis, pooled adverse event (AE) rates in Entyvio-treated patients were reported for infections, serious AEs and serious infections. These reported rates were consistent with previous vedolizumab clinical trial results in patients with moderate to severe UC or CD and support the long-term safety profile of Entyvio in clinical practice.
“Real-world data furthers our understanding of the efficacy and safety signals we see in placebo-controlled registration trials, which have strict selection criteria and may not be illustrative of the patient population seen in clinical practice. A meta-analysis adds stability to such real-world observations, especially when based on very large patient numbers. In this case, vedolizumab real-world data were systematically collected and analyzed with the rates of serious infections, infusion-related reactions and malignancies consistent with data previously reported in clinical trials in patients with moderate to severe UC or CD,” said Stefan Schreiber, M.D., Ph.D., Professor of Medicine and Gastroenterology, Translational Inflammation Research, Christian Albrechts University, Kiel, Germany.
Results from a second U.S-specific analysis assessing the real-world use of immunosuppressives (IM) across a total of 567 patients, identified via The Explorys Universe database, also provide information on the safety profile of Entyvio. Of the 567 patients (58.6% female; 41.4% male), 68.4% had CD and 31.6% had UC. The mean age at index was 44 and on average, patients initiated vedolizumab 4.5 years following their initial diagnosis. The findings report, in real-world clinical practice, of the 45.4% of patients without a history of IM therapy, 87% of patients treated with Entyvio were not on IM therapy during follow-up. Of the 54.6% of patients with a history of IM therapy, 61% of patients treated with Entyvio were not on IM during maintenance treatment during follow-up. In this analysis, lower rates of healthcare resource utilization were observed among patients without a history of IM use.
“These data provide additional insight on the usage patterns, long-term safety profile and outcomes of Entyvio use in real-world clinical practice,” said Mona Khalid, Senior Director, Head of Evidence and Value Generation, Takeda Pharmaceuticals. “We look forward to the continued expansion of our body of knowledge on the safety profile of Entyvio treatment in ulcerative colitis and Crohn’s disease, and are pleased to present these real-world results at the UEG Week in Barcelona.”
