Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary endpoint will be evaluated through the following variables: PUCAI score, IFX levels, and steroid treatment.

Clinical response to IFX will be evaluated through the PUCAI score. The response will be considered clinically significant if PUCAI points continue maintained below 30 during the study period. The IFX response will also be determined by IFX serum levels. A therapeutic IFX level, i.e. for achieving an adequate clinical response, is established above 6 μg/mL. Finally, the necessity, or not, of a steroid treatment during the study period will also be indicative of successful efficacy with GMA.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial has the following objectives:

Primary objective (PO):

The primary endpoint will be evaluated through the following variables: PUCAI score, IFX levels, and steroid treatment.

Clinical response to IFX will be evaluated through the PUCAI score. The response will be considered clinically significant if PUCAI points continue maintained below 30 during the study period. The IFX response will also be determined by IFX serum levels. A therapeutic IFX level, i.e. for achieving an adequate clinical response, is established above 6 μg/mL. Finally, the necessity, or not, of a steroid treatment during the study period will also be indicative of successful efficacy with GMA.

Secondary objectives (SO):

1. Quantification of IFX trough and ATI levels, and description of the IFX dose at baseline, 12 and 40 weeks of follow-up.
2. Measurement of PUCAI score at baseline, 12 and 40 weeks of follow-up.
3. Patients maintaining clinical response off steroids, 12 and 40 weeks of follow-up.
4. Patients experiencing flares-ups during the study period.
5. Quantification of fecal calprotectin level at baseline, 12 and 40 weeks of follow-up. Fecal calprotectin is associated with clinical remission with levels higher than 150 μg/g.
6. Measurement of C-reactive protein, erythrocyte sedimentation rate, hemoglobin, albumin, platelet levels at baseline, 12 and 40weeks of follow-up.
7. Quantification of leucocyte counts in peripheral blood at baseline, 12 and 40 weeks of followup.
8. Monitoring of AEs during the study period

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Adacolumn

Adacolumn is a non-pharmacological treatment which reduces the inflammation by removing specifically targeted white blood cells from the blood circulation. The Adacolumn is designed to be used in combination with the Adamonitor and its Adastand, and the Adacircuit. The column has a capacity of 335 mL and is filled with cellulose acetate beads of 2 mm in diameter as the column adsorptive leukocytapheresis carriers. The carriers are bathed in 130 mL of sterile saline until use when the column is primed with additional sterile saline and then with heparinized saline prior to use.

Patients will receive 10 sessions with Adacolumn. It would be reduced between 5 - 10, according to the patient´s response and following PI valuation. Patients will receive Adacolumn with IFX for that period of time.

Patients will have received previously IFX for 12-16 weeks. visits will be conducted every week, for the application of Adacolumn.

Group Type EXPERIMENTAL

Intervention Type DEVICE

The study will consist of 10 sessions of Adacolumn® treatment (once per week) and a follow-up period (from week 12 to week 40 since study inclusion).

Inclusion Criteria

1. Patients under 18 years of age and weighing ≥25 kg at the time of study initiation.

4. Patients who have received IFX between 12 and 16 weeks prior to the study initiation.
5. Patients who have showed a clinical response to IFX at the time of study initiation (defined as a reduction of at least 15 points in PUCAI score and being maintained below 30 points).
6. Patients with therapeutic IFX blood levels (above 6 μg/mL) at the time of study initiation.
7. Patient´s legal guardian must be willing and able to give written informed consent, and the patient must be willing to give written informed assent (if applicable as determined by the Ethics Committee) and comply with the Study visit Schedule.

Exclusion Criteria

1. Patients who have received another anti-TNF prior to entry in the study.
2. Patients with a peripheral circulation count of less than 2,000 granulocytes per μL.
3. Pregnant and lactating of childbearing potential patients.
4. Participation in another study or use of any experimental therapy within 30 days before day 1 of Study initiation.
