The primary objective of this study is to obtain well-characterized blood specimens from subjects with a clinical diagnosis of inflammatory bowel disease (IBD) treated with vedolizumab (VDZ), presenting with initial failure to respond or loss of response to treatment or intolerance to VDZ. The purpose of this study is to enable analytical validation of the Anser® VDZ test, design to measure serum levels of VDZ and antibodies to VDZ (ATV).

Inclusion criteria:

  • Subjects either previously were or currently are on VDZ treatment, experiencing primary treatment failure or secondary loss of response or intolerance to VDZ treatment.
  • Subjects understand the procedures and requirements of the study by providing written informed consent or including consent and authorization for protected health information disclosure.

This study includes two (2) visits and takes about two (2) hours.
You will not directly benefit from participation in this study and it will not impact your clinical care and management. If the research is successful in developing a test for monitoring vedolizumab treatment, there may be benefit to future subjects prescribed vedolizumab for monitoring of therapy efficacy for optimization of treatment.
You will be paid $50 after each blood draw. There will be no more than two (2) blood draws.
