Vedolizumab Immunogenicity With Long-Term or Interrupted Treatment of Patients With Inflammatory Bowel Disease.

ABSTRACT: Patients in the GEMINI 1 or 2 study (NCT00790933; Eudra CT2008-002784-14) with ulcerative colitis or Crohn disease had low immunogenicity rates after vedolizumab treatment for up to 52 weeks. We report immunogenicity rates from the GEMINI long-term safety (LTS) study using a new drug-tolerant electrochemiluminescence assay, including analyses in patients who received continuous vedolizumab induction and maintenance in GEMINI 1 or 2 and long term safety, or vedolizumab induction and placebo maintenance in GEMINI 1 or 2 followed by re-treatment in long term safety (treatment interruption). Patients were enrolled in GEMINI long term safety from GEMINI 1, 2, or 3, or as de novo vedolizumab-treated patients; all received vedolizumab 300 mg intravenously every 4 weeks.
