Value of Pharmacokinetic Assays in the Prediction of Therapeutic Response in Ulcerative Colitis

Study Purpose

Vedolizumab (VDZ) is a monoclonal antibody that binds to the heterodimer α4β7 integrin and which has shown its efficacy in Ulcerative Colitis (UC) by inducing and maintaining clinical response/remission. The French marketing authorization was obtained for Ulcerative Colitis in patients in failure with anti-Tumor Necrosis Factor (anti-TNF) agents. In the pivotal study, correlation between drug levels and clinical response during induction and maintenance therapy were reported. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. Up to now, data on the pharmacologic VDZ parameters are scarce and the relationships as well as the predictive value of the measurement of VDZ concentrations and VDZ monoclonal antibodies (mAbs) during the induction and maintenance phases remains unknown. It could be of paramount interest to early identify UC patients under VDZ who will be responders to VDZ induction and to identify those who will achieve clinical remission under maintenance therapy with VDZ.

Recruitment Criteria

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Accepts Healthy Volunteers
No

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

More Inclusion & Exclusion Criteria

Inclusion Criteria:

  • - - Aged over 18 years - Men or non-pregnant women - Patients with a diagnosis of ulcerative colitis who requires to start VDZ - Moderate to severe active ulcerative colitis defined as a total mayo score ranging from 6 to 12 and endoscopic Mayo score above 1 - UC patients with previous failure with TNF antagonist agents and unacceptable side-effects from steroids, and/or immunosuppressive agents (i.e., azathioprine, 6-mercaptopurine, or methotrexate).
In France, VDZ has to be prescribed only in patients in failure or intolerant to anti-TNF.
  • - Stable doses of oral prednisone (≤30 mg per day) or budesonide (≤9 mg per day), are allowed at stable dose for at least 4 weeks-before inclusion.
Concomitant immunosuppressive agents, mesalamine, are allowed at stable dose for at least three months before inclusion. Steroid tapering has to be set up at Week 6 after starting VDZ, according to the European Crohn's and Colitis Organisation (ECCO) recommendations.
  • - Informed written consent given.

Exclusion Criteria:

  • - - Existing pregnancy, lactation, or intended pregnancy within the next 15 months - Minors or History of disease, including mental/emotional disorder that might interfere with their participation in the study - Serious secondary illnesses of an acute or chronic nature, which in the opinion of the investigator renders the patient unsuitable for inclusion into the study - Inability to comply with the protocol requirements - Inability to fill in the diary cards during the last 7 days before each visit - Severe Acute UC needed hospitalisation - Known previous or concurrent malignancy (other than that considered surgically cured, with no evidence for recurrence for 5 years) - Short bowel syndrome - Previous treatments with vedolizumab, natalizumab, efalizumab or rituximab.
  • - Previous treatment with adalimumab within 30 days prior enrollment or infliximab and certolizumab pegol within 60 days before enrollment - Prior extensive colonic resection, obstructive (symptomatic) intestinal stricture, abdominal abscess, active or latent tuberculosis, - Clostridium difficile superinfection; - Indeterminate colitis - Concomitant leukocyte apheresis.
- Any contraindication to vedolizumab therapy - Patients who denied the protocol, not ability to accept or sign consent of the protocol - Subject involved in another clinical trial

Trial Details

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

Trial ID:
NCT03724929

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

The contribution of the pharmacokinetic studies of monoclonal antibodies (anti-TNF antibodies currently) has assumed increasing importance of its use in clinical practice. Therapeutic algorithms for both Infliximab (IFX) and Adalimumab (ADA) have been published and are used by many expert teams in the event of loss of therapeutic response. Similarly, the concentrations are assuming important in the indication of therapeutic de-escalation. Lastly, the assays may predict medium-term therapeutic response to treatment and thus enable proposal of preventive therapeutic changes (5). The Gemini 1 study (phase 3 vedolizumab vs.#46; placebo in Ulcerative Colitis) showed a correlation between drug levels and clinical response during induction and maintenance therapy. Moreover, in 3.7% of cases, anti-vedolizumab antibodies were reported during the time-course and 1% had samples that were persistently positive. (1). In addition, we have decided to assess the clinical response to VDZ induction at W10 (Week 10), as the Gemini III trial for Crohn Disease (Crohn Disease) have reported, among patients who had experienced previous Tumor Necrosis Factor (TNF) antagonist failure, that 15% of those given vedolizumab versus 12% under placebo were in remission at W6 (P=0.433) whereas a higher proportion of them were in remission (26%) under VDZ when compared with the placebo arm (12%) at week 10. Therefore, in clinically non-responders at W10, an additional dose of 300 mg of VDZ will be infused at W10 and every four weeks.
