Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All eligible patients enrolled on the study will be entered into the central randomisation system. The patient number assigned at the time of randomisation will be the primary identifier for the patient. Randomisation will be performed by the NHMRC Clinical Trials Centre which will provide a centralised tele-randomisation service that will randomly allocate patients to nicotinamide or placebo groups in a 1:1 ratio stratified by baseline skin cancer count, gender, transplant group (renal, liver, heart, lung), current retinoid and/or mTor inhibitor use and study site. The pharmacist will provide the drug kit allocated by the system for the patient, recording the kit number in the pharmacy log. The study number, patient name and MRN will then be written on the medication bottle.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised to nicotinamide or placebo in a 1:1 ratio using a minimisation method stratified by baseline skin cancer count, (6 or more versus 2-5 previous nonmelanoma skin cancers), gender, study site, transplant group (renal, liver, heart, lung), current oral retinoid use and current mTor inhibitor use.
