"IL-1β Blockade to Prevent Immunothrombosis in Recipients of a Pancreatic Organ"

Pancreas transplantation is the treatment of choice for curing diabetes by restoring long-term endogenous insulin secretion. However, the increased risk of rejection compared to other transplants, and especially the risk of early graft loss due to immunological thrombosis, are major obstacles to this procedure.

IL-1β blockade is commonly used in islet transplantation, as it has demonstrated a benefit in terms of graft survival when administered immediately postoperatively, in combination with TNFα blockade18.

The ILIPO study therefore aims to evaluate the safety of anti-IL-1β treatment as an adjunct to the regimen currently used in our department for pancreatic transplants.

Inclusion criteria

• Patient admitted to Nantes University Hospital for a pancreatic transplant (alone or combined with a kidney transplant)
• Pancreatic graft rank: 1, 2 or 3
• Affiliated with the social security scheme
• Written consent to participate in the study
• Women must meet one of the following criteria at the time of inclusion:

• use adequate contraceptive measures and have a negative pregnancy test (urine test) before receiving the first dose of the trial drug
• or be postmenopausal (aged over 50 with amenorrhoea for at least 12 months after stopping all exogenous hormone treatments);
• or (if under 50 years of age) have been amenorrhoeic for at least 12 months after stopping exogenous hormone treatments and with luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels corresponding to postmenopausal levels;
• or have undergone irreversible surgical sterilisation by hysterectomy, bilateral oophorectomy or bilateral salpingectomy (this operation must be documented).
• Male patients with a partner must be willing to use male contraception (condoms) during the trial and for up to 90 days after the last dose of the trial drug. partners of male subjects participating in the trial may use hormonal contraceptives as one of the acceptable methods of contraception, as they will not be receiving the trial drug (i.e., oral hormonal contraception, cap, diaphragm, or sponge with spermicide).

Exclusion criteria

• Patient under guardianship/curatorship
• Patient under judicial protection
• Pregnant or breastfeeding woman
• Positive tuberculin skin test in the last 12 months
• Hepatitis B viral replication in the last 12 months
• History of known hypersensitivity to Anakinra or any of its excipients or to proteins derived from E. coli
• Neutropenia < 1500/mm3 prior to transplantation (daily assessment)
• Patient unable to understand and speak French
• Patient participating in another interventional study (outside RIRCM)
