MOdel-Informed Precision Dosing of Ustekinumab and VEdolizumab in Inflammatory Bowel Disease

Официальное название

MOdel-Informed Precision Dosing (MIPD) of Ustekinumab and VEdolizumab in Inflammatory Bowel Disease - An Independent Randomized Controlled Trial

Обзор

The goal of this clinical trial is to investigate if dosage of Ustekinumab (UST) and Vedolizumab (VDZ) based on Model-Informed Precision Dosing (MIPD) is equally as efficient in keeping adults with Inflammatory Bowel Disease (IBD) in remission as management based on what the treating physician deems best. The main question is: Is using pharmacokinetic-pharmacodynamic (PK-PD) models to predict the appropriate dose and dosing interval for VDZ and UST at least as effective as current practices in maintaining IBD remission. As above mentioned the comparison-group is adults with IBD, treated with UST or VDZ, managed as the physician deems best. Participants will: Have blood and stool tests done, as well as answer a questionnaire 4th weekly Have their dosage frequency decided on either by the PK-model or as the physician deems best visit the clinic once every 24 weeks for checkups. Have an endoscopy done at completion of the study (if the disease is primarily located in the small intestine, MRI or capsule endoscopy will be used instead)

Подробное описание

Patients will 4th weekly have their drug-concentration in blood measured (and if low, also antidrug antibodies). Hemoglobin, Albumin, CRP and white blood cell count will also be done, as well as a stool-sample for calprotectin measurement.

For the control group however, the clinicians and patients will be blinded for the results of the blood- and stool samples, and the samples for drug concentration will not get analyzed before end of study.

4th weekly they will also answer PRO2 questionnaire, as well as the VAS-F. 8th weekly they will in addition to above mentioned also answer the EQ-5D-5L questionnaire.

At inclusion, after 24 weeks, and at 48 weeks the patients will in addition to the above mentioned also answer the short IBDQ and WPAI questionnaires, as well as be seen in the outpatient clinic to obtain HBI or SCCAI score as applicable, as well as to document any changes in concomitant medication or diseases, and to register if any serious adverse events have presented.

At completion of the trial, patients will have a endoscopy done.

In one subprotocol, the investigators will include 20 patients from Odense to have an endoscopy at both inclusion and completion. Here they will also have biopsies taken from all segments of the colon, which will be stores in a biobank for future research.

In another subprotocol 20 patients will be included to have a intestinal ultrasound done at inclusion and completion.

In a biobank for future research the investigators will also store serum-samples, buffy coat, and stool samples collected at inclusion, after 24 and 48 weeks from all included patients.

Вмешательства

• Препарат PK-model to decide when to dose Vedolizumab and Ustekinumab
  the pharmacokinetic model will include information about inflammatory parameters both in blood- and fecal samples, as well as weight, sex, previous treatments and drug concentration.
