Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients will be recruited through file review and direct referral from Nephrologists in the renal transplant outpatient department at Royal Prince Alfred Hospital. After signing the consent form, patients will go into 1 month of screening to ensure stable BGL levels. Patients will then be randomised as per the procedures below. It is not a blinded study.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The patients will be randomised 1:1 to each group, stratified by time post-transplant (less than 6 months vs more than 6 months). The randomisation sequence will consist of computer-generated random permuted blocks of size 4-8. The sequence will be stored in numbered, sealed, opaque envelopes. The envelopes will be opened by non-study personnel following successful completion of screening.
Masking / blinding

Summary
Brief summary
Diabetes is common after renal transplant and gliclazide is often used as a first line treatment. The objective of the trial is to show that Vildagliptin can be safely used to control hyperglycaemia, with less hypoglycaemic episodes than its comparator of Gliclazide. 48 participants will be randomly allocated to either the intervention arm of oral tablets of 50mg once daily or twice daily of vildalgliptin or to the comparator arm of oral tablet 60mg Gliclazide modified release once daily. The patients will be followed for 16 weeks to assess for hypoglyacaemic episodes and safety.
