On Sept. 4, Takeda Pharmaceutical Company Ltd., announced that it received priority review status from the FDA for its drug vedolizumab, an investigational antibody for the treatment of adults with moderately to severely active Crohn’s disease (CD) and ulcerative colitis (UC). Takeda submitted a biologics license application (BLA) to the FDA in June for the treatment of CD and UC; the UC application will receive priority review, and the application for CD will be reviewed under the standard timeline.
The FDA grants priority review status for drugs that are designed to treat a serious condition, and that if approved, would provide a significant improvement in safety or effectiveness. Priority review designation allows for an eight-month review period compared with the standard 12-month review.
“The need to seek new treatment options is well recognized,” said William J. Sandborn, MD, chief, Division of Gastroenterology, and professor of medicine, University of California, San Diego School of Medicine, in a press statement. “Vedolizumab has demonstrated the potential to be another possible treatment option for people with moderately to severely active CD and UC.”
Vedolizumab is a humanized monoclonal antibody that specifically antagonizes α4β7 integrin and inhibits it from binding to its target receptor, mucosal addressin cell adhesion molecule-1 (MAdCAM-1). MAdCAM-1 is preferentially expressed on blood vessels and lymph nodes of the gastrointestinal tract. It interacts with α4β7 integrin, which is expressed on a subset of circulating white blood cells, to mediate the inflammatory process in patients with CD and UC.
Takeda’s BLA submission is supported by four Phase III clinical studies—GEMINI I, II and III, and GEMINI LTS (Long-Term Safety)—which comprise the GEMINI StudiesTM, a clinical program designed to investigate the efficacy and safety of vedolizumab in clinical response and remission in patients with moderate to severe CD and UC. Patients enrolled in the studies failed at least one conventional therapy for inflammatory bowel disease, including corticosteroids, immunomodulators and/or a tumor necrosis factor–alpha antagonist. The results of the Phase III studies of vedolizumab in patients with CD and UC were published recently in the New England Journal of Medicine (Sandborn WJ et al. N Engl J Med 2013;369:711-721 and Feagan BG et al. N Engl J Med 2013;369:699-710, respectively).
According to Takeda, vedolizumab has been studied in 2,700 patients in nearly 40 countries, making it the largest Phase III clinical trial program to date to simultaneously evaluate CD and UC. GEMINI LTS is an ongoing, open-label, long-term safety study of vedolizumab and is designed to collect data on the occurrence of important clinical safety events resulting from the administration of vedolizumab.
