Clinical Trial Summary

OPERA Study is a randomized, open-label, prospective, pilot, and a monocentric clinical trial involving outpatients within Abu Dhabi Stem Cells Center (ADSCC) with a confirmed diagnosis of type 1 diabetes mellitus (T1DM). The patients will be randomly allocated (1:1) in a parallel assignment involving two groups of participants: Group A (Regular-intensity arm): Extracorporeal Photopheresis (ECP) on a regular-intensity regimen described in the Protocol as add-on T1DM standard of care, or Group B (Accelerated-intensity arm): ECP on an accelerated regimen plus T1DM standard of care.

Clinical Trial Description

The standard of care is defined as per the "DOH Standards for diagnosis, management and data reporting for diabetes" in combination with the DOH recommended NICE (UK National Institute for Health and Care Excellence) guidelines "Type 1 diabetes in adults: diagnosis and management (NG17)". OPERA Study will be fully conducted in ADSCC, including the patient assessment and inclusion, randomization, ECP procedures, and follow-up consultations, according to this Protocol and GCP principles. All patients will receive T1DM standard of care, plus additional ECP protocols on two regimens of investigational interventions. The primary objective is the safety assessment of ECP, to be assessed by the tolerability to the ECP procedures, incidence of treatment-emergent adverse events (TEAEs), adverse events of special interest (AESIs), and serious adverse events (SAEs) assessed by the CTCAE v5.0, and the WHO-UMC causality assessment system. The other primary objective is the preliminary efficacy assessment of the ECP as an add-on treatment to the standard of care for T1DM patients, assessed by the exogenous insulin use, HbA1c levels, C-peptide levels, and clinically important hypoglycemic episodes. The secondary objective is the assessment of the immune response profile in T1DM patients receiving standard of care and additional ECP procedures. The trial is approved by the institutional ADSCC Research Ethics Committee (REC) and written informed consent will be obtained from all patients. OPERA Study will be conducted following the principles of the Declaration of Helsinki and ICH-GCP guidelines. ;
