E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1. To compare the evolution of advanced diabetic retinopathy between
the 2 groups of Type 1-diabetic patients undergoing simultaneous
pancreas/kidney allograft transplantation in terms of the prevalence of
micro vascular retinal abnormalities (micro aneurysms, micro
hemorrhages and hemorrhages), range retinal neovascularization and
macular thickness at 1 and 2 years pot-transplant
2 a) To compare other parameters of diabetic retinopathy (visual
acuity, intraocular bleeding, need for laser therapy and other) between
the 2 groups
b) To compare graft survival, rejection rate, treatment tolerance and the
time to wound healing between the 2 groups |
|
E.2.2 | Secondary objectives of the trial |
a) i. Change in visual acuity
ii. need for laser therapy
iii. new vessels formation within the field assessed by the color fundus
stereoscopic photographs
iv. new occurrence or change in cataract grading scale of more than 1 step
v. changes in retinal thickness compared to baseline examination assessed by OCT. Changes will be compared in the whole group and separately in subjects with pre-transplant OCT signs of macular (central macular thickness of > 250 μm or more)
vi. new occurrence of intravitreal bleeding registered by the patient and confirmed by the ophthalmologist
vii. retinopathy level assessed using the methodology of the EURODIAB IDDM Complications Study [1]
b) General parameters (patient and graft survival rates; rejection rate; treatment intolerance; the time to complete wound healing; blood glucose and C-peptide levels; creatinine clearance rate; glycosylated hemoglobin values) |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1 Male or female patients, of 18 to 65 years of age, with a pre- or an
end-stage renal failure, Type 1-diabetic nephropathy, C¬-peptidenegative
(defined as C-peptide upper limit 0.2 nmol/l ,. If C-peptide is >
0.1 nmol/l, mixed-meal test will be performed with C-peptide upper limit
> 0.2 nmol/l).
2 Female patients of childbearing age must have a negative pregnancy
test and must agree to maintain effective birth control practice
throughout the study period (2 years).
3 Patient must have signed the Patient Informed Consent Form.
4 Patient must receive a primary simultaneous pancreas/kidney (SPK)
cadaver transplant, with either intestinal or bladder and either portal or

E.4 | Principal exclusion criteria |
1. Patient is pregnant or breastfeeding.
2. Patient is allergic or intolerant to any drug comprising both
immunosuppressive protocols
3. Patient has a positive T-cell cross-match on the most recent serum
specimen.
4. Patient is known for active liver disease or has significant liver
disease; defined by ASAT and ALAT serum levels greater than 3 times the
upper limit of normal.
5. Patient has history of prothrombotic disorders.
6. Patient has malignancy or history of malignancy, with the exception of
adequately treated localized squamous cell or basal cell carcinoma,
without recurrence.
7. Patient has been included in another clinical trial protocol for any
investigational drug within 4 weeks prior to randomization.
8. Patient has any form of substance abuse, psychiatric disorder or
condition, which, in the opinion of the investigator, may invalidate
communication.
9. Patient receives a kidney transplant from a living donor, or receives
segmental pancreatic transplant, or a previous kidney transplant alone.
10. Pancreatic duct occlusion technique.
11. Donor is older than 65 years of age.
12. The use of any other commercial or investigational
immunosuppressive drugs is prohibited if it is not clinically indicated.
13. Patient has an immunological high risk, defined as a PRA grade >
50% |

E.5 End points |
E.5.1 | Primary end point(s) |
a) need for laser therapy except procedures that had been scheduled
already pre-transplant and were performed not later than 4 months
post-transplant
b) newly diagnosed proliferative retinopathy that was not present on
the pre-transplant examination
c) newly diagnosed clinically significant macular edema
d) worsening of visual acuity of more than 2 rows of Snellen´s
optotypes
e) occurrence of blindness |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The study will last 2 years with a primary endpoint at 1 year and at the
study end. Extension of the study duration for survival data may be
decided by the Study board. Patients will be enrolled over a period of 3
years. |
|
E.5.2 | Secondary end point(s) |
a) Ophthalmic parameters:
i. Change in visual acuity
ii. need for laser therapy except procedures that had been scheduled
already pre-transplant and were performed not later than 4 months
post-transplant
iii. new vessels formation within the field assessed by the color fundus
stereoscopic photographs (performed according to the EURODIAB IDDM
XML File Identifier: jgXRtxN9yCiFR7cToieRD2u4L7Y=
Page 12/21
Complications Study [1] ETDRS report number 10 [2]
iv. new occurrence or change in cataract grading scale of more than 1
step
v. changes in retinal thickness compared to baseline examination
assessed by OCT. Changes will be compared in the whole group and
separately in subjects with pre-transplant OCT signs of macular (central
macular thickness of > 250 μm or more)
vi. new occurrence of intravitreal bleeding registered by the patient and
confirmed by the ophthalmologist
