National GMA Post-market Clinical Follow-up Study (GRACE)

It is planned to enrol a minimum of 350 patients from approximately 30 sites. To avoid screening biases, the patients to be included per site will be selected consecutively from among those who meet the eligibility criteria to participate in the study.

A national, multicentre, noninterventional post-market clinical follow-up (PMCF) study with an estimated follow-up period of 12 months after completion of GMA therapy to evaluate the efficacy of Adacolumn® GMA in actual conditions of use, as specified in the product instructions for use, in adult patients diagnosed with UC or CD. Approximately 350 patients from about 30 centres in Spain are planned to be included.

The standard regimen according to product instructions for use is one session per week for 5 consecutive weeks, although in specific cases continuous regimens have been established for maintenance (one or two sessions per month) or others for induction (two sessions per week). The use of a higher number of sessions seems to increase efficacy from 40% with 5 sessions to 80% with 10 in the more refractory cases and may achieve a greater reduction in steroid use. In Europe, where GMA is used in different scenarios, it is routinely being used in 7 to 10 sessions.

The study will consist of a maximum of 4 visits: a baseline visit, which will coincide with patient inclusion in the study, and 3 follow-up visits at 4 (±2 weeks) (month 1), 24 (±2 weeks) (month 6) and 48 (±2 weeks) (month 12) weeks after the last session of induction apheresis.

All visits scheduled during the study will coincide with any of the patient visits made as part of routine clinical follow-up, without interfering with the investigator's clinical duties. Note: In the event that a patient discontinues Adacolumn® GMA, the reasons for discontinuation of the procedure will be recorded and the change in treatment for IBD, if any.

Once the patient has been adequately informed, his/her eligibility has been confirmed and he/she has signed the informed consent (IC), the investigator will start data collection in an appropriate and precise manner. Therefore, no diagnostic or therapeutic intervention outside of routine clinical practice will be applied. To ensure the noninterventional nature of the study, the data will be collected provided they are available in the patient's medical record or can be collected during patient visits to his/her physician as part of actual clinical care (as in the case of questionnaires used as source documents).

Adacolumn® is a medical device intended for modifying the biological or chemical composition of the blood (class IIb), according to Regulation (UE) 2017/745 on Medical Devices, manufactured by Japan Immnunoresearch Laboratories, JIMRO (Takasaki, Japan). It consists of a 335 ml column formed by cellulose acetate beads of 2 mm in diameter bathed in saline, where granulocytes (65%), monocytes (55%), and only 2% of lymphocytes are selectively adsorbed.

Adacolumn® is indicated for induction of remission in patients with IBD (active UC and CD), for suppression of subjective and objective symptoms in patients with rheumatoid arthritis in the inflammatory stage whose symptoms might be resistant to standard drug therapy, for treatment of patients with ocular Behcet disease and for treatment of patients with systemic lupus erythematosus.

In this study, the intended use of Adacolumn® is for application of GMA in patients diagnosed with IBD, both UC and CD
