Investigational Subcutaneous Formulation of Vedolizumab Meets Primary Endpoint in Achieving Clinical Remission at Week 52 in Patients with Moderately to Severely Active Crohn's Disease

Osaka, Japan, July 22, 2019 – Takeda Pharmaceutical Company Limited (TSE:4502/NYSE:TAK) (“Takeda”) today announced top-line results from the VISIBLE 2 clinical trial evaluating the efficacy and safety of an investigational subcutaneous (SC) formulation of the gut-selective biologic vedolizumab as maintenance therapy in adult patients with moderately to severely active Crohn's disease (CD) who achieved clinical response* at week 6 following two doses of open-label vedolizumab intravenous (IV) therapy at weeks 0 and 2.

 

[1] In evaluating the primary endpoint of the trial, a statistically significant proportion of patients receiving vedolizumab SC achieved clinical remission** at week 52 compared to placebo. Patients received vedolizumab SC beginning at week 6 and every 2 weeks up to week 50.1 Adverse events were consistent with the known safety profile of vedolizumab IV, and no new signals were identified.

 

“Meeting the primary endpoint of the VISIBLE 2 study marks a crucial step in our efforts to help patients with Crohn’s disease as to how they may receive treatment with vedolizumab, whether that is intravenously or subcutaneously. These data, alongside the pivotal VISIBLE 1 results in ulcerative colitis, provide a more comprehensive picture of the new investigational subcutaneous formulation of vedolizumab as maintenance therapy for both ulcerative colitis and Crohn’s disease,” said Asit Parikh, MD PhD, Head of Takeda’s Gastroenterology Therapeutic Area Unit.

 

These results will be shared with regulatory authorities and further data from the VISIBLE 2 trial will be presented at a future scientific congress. The subcutaneous formulation of vedolizumab forms part of Takeda’s ongoing commitment to meet the individual preferences of patients worldwide.

 

VISIBLE 2 is a phase 3, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of vedolizumab SC as maintenance therapy in patients with moderately to severely active CD.1 The study enrolled 644 participants, all of whom had an inadequate response with, loss of response to, or intolerance to corticosteroids, immunomodulators, or tumor necrosis factor-alpha (TNFα)-antagonist therapy prior to being enrolled.1 Patients who achieved clinical response at week 6 (n=410),[2] following two doses of open-label vedolizumab 300 mg IV therapy at weeks 0 and 2, were randomized into one of two treatment groups, vedolizumab 108 mg SC or placebo SC.1 Both treatment groups received a subcutaneous injection every two weeks starting at week 6 up to week 50.1

 

* Clinical response is defined as a ≥70 point decrease in Crohn's Disease Activity Index (CDAI) score from baseline (week 0).2

** Clinical remission is defined as a Crohn's Disease Activity Index (CDAI) score ≤150 at week 52.1

About the VISIBLE Clinical Trial Program

The VISIBLE clinical trial program aims to assess the efficacy and safety of an investigational subcutaneous (SC) formulation of vedolizumab as maintenance therapy in adult patients with moderately to severely active ulcerative colitis (UC) or Crohn’s disease (CD).1,[3],[4]

 

VISIBLE consists of three phase 3 studies involving over 1,000 UC and CD patients which includes two randomized, double-blind, placebo-controlled studies examining the proportion of patients achieving clinical remission at week 52, and an open-label extension study to determine the long-term safety and efficacy of vedolizumab SC.1,3,4

 

About Ulcerative Colitis and Crohn’s Disease

Ulcerative colitis (UC) and Crohn’s disease (CD) are two of the most common forms of inflammatory bowel disease (IBD).[5] Both UC and CD are chronic, relapsing, remitting, inflammatory conditions of the gastrointestinal tract that are often progressive in nature.[6],[7] UC only involves the large intestine as opposed to CD which can affect any part of the GI tract from mouth to anus.[8],[9] CD can also affect the entire thickness of the bowel wall, while UC only involves the innermost lining of the large intestine.7,8 UC commonly presents with symptoms of abdominal discomfort, loose bowel movements, including blood or pus.8,[10] CD commonly presents with symptoms of abdominal pain, diarrhea, and weight loss.6 The cause of UC or CD is not fully understood; however, recent research suggests hereditary, genetics, environmental factors, and/or an abnormal immune response to microbial antigens in genetically predisposed individuals can lead to UC or CD.8,[11],[12]

 

About Entyvio® (vedolizumab)

Vedolizumab is a gut-selective biologic and is approved as an intravenous (IV) formulation.[13],[14] It is a humanized monoclonal antibody designed to specifically antagonize the alpha4beta7 integrin, inhibiting the binding of alpha4beta7 integrin to intestinal mucosal addressin cell adhesion molecule 1 (MAdCAM-1), but not vascular cell adhesion molecule 1 (VCAM-1).[15] MAdCAM-1 is preferentially expressed on blood vessels and lymph nodes of the gastrointestinal tract.[16] The alpha4beta7 integrin is expressed on a subset of circulating white blood cells.15 These cells have been shown to play a role in mediating the inflammatory process in ulcerative colitis (UC) and Crohn’s disease (CD).15,[17],[18] By inhibiting alpha4beta7 integrin, vedolizumab may limit the ability of certain white blood cells to infiltrate gut tissues.15

 

Vedolizumab IV is approved for the treatment of adult patients with moderately to severely active UC and CD, who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a tumor necrosis factor-alpha (TNFα)-antagonist.13,14 Vedolizumab IV has been granted marketing authorization in over 60 countries, including the United States and European Union, with more than 330,000 patient years of exposure to date.2

 

Therapeutic Indications (vedolizumab IV)

 

Ulcerative colitis

Vedolizumab is indicated for the treatment of adult patients with moderately to severely active ulcerative colitis who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a tumor necrosis factor-alpha (TNFα) antagonist.

 

Crohn’s disease

Vedolizumab is indicated for the treatment of adult patients with moderately to severely active Crohn’s disease who have had an inadequate response with, lost response to, or were intolerant to either conventional therapy or a tumor necrosis factor-alpha (TNFα) antagonist.
