Key inclusion & exclusion criteria

Inclusion criteria:

- Ages 18-65 years, inclusive.

- Patients eligible for pancreatic islet transplantation based on local accepted
practice and guidelines. This includes at least: a)clinical history compatible with
T1D with insulin-dependence for >5 years; b) undetectable stimulated (arginine or
MMTT) C-peptide levels (<0.3 ng/mL) in the 12 months before transplant. Sites will
comply with any additional or more stringent criteria locally accepted, as per centre
practice.

- Patients with adequate renal reserve as per calculated creatinine clearance (CLcr) >
60 mL/min according to the Cockcroft-Gault formula (1976).

- Planned intrahepatic islet transplantation alone from a non-living donor with brain
death.

- Planned infusion of 4000 to 7000 islet equivalent (IEQ)/kg body weight.

- Patients willing and able to comply with the protocol procedures for the duration of
the study, including scheduled follow-up visits and examinations.

- Patients given written informed consent, prior to any study-related procedure not
part of normal medical care, with the understanding that consent may be withdrawn by
the patient at any time without prejudice to their future medical care.

Exclusion criteria:

- Recipients of any previous transplant, except from recipients of a previous
pancreatic islet transplantation that has failed, are off immunosuppression since at
least 1 year and have negative anti-HLA.

- Recipients of islet from a non-heart beating donor.

- A body mass index >30 kg/m2 or patient weight <45 kg.

- Pre-transplant average daily insulin requirement >1 IU/kg/day.

- Pre-transplant HbA1c >11%.

- Patients with hepatic dysfunction as defined by increased ALT/AST > 3 x ULN and
increased total bilirubin > 3mg/dL [>51.3 micromol/L]).

- Patients who receive treatment for a medical condition requiring chronic use of
systemic steroids.

- Treatment with any anti-diabetic medication other than insulin within 4 weeks of
transplant.

- Use of any investigational agent within 4 weeks of enrolment.

- Hypersensitivity to:

- ibuprofen or to more than one non steroidal anti-inflammatory drug

- medications belonging to the class of sulfonamides, such as sulfamethazine,
sulfamethoxazole, sulfasalazine, nimesulide or celecoxib.

- Pregnant or breast-feeding women; unwillingness to use effective contraceptive
measures (females and males).

Sites will comply with any additional exclusion criteria locally accepted, as per centre
practice.
