|---|---|
| Main Objective: The aim of this study is to determine possible molecular changes on large scale gene expression profiling after treatment with Metvix® Photodynamic therapy (PDT) of Actinic Keratoses (AK) and cancerised field in renal transplant recipients. It will be studied if Metvix® reduces the number of molecular aberrations leading to epidermal neoplasia in the treated area. Both the treatment effect [on existing lesions (actinic keratoses)] and the prophylactic effect (prevention of appearance of new lesions) will be measured and linked to the effect on gene expression.;Secondary Objective: In addition to the main objectif the Investigator will assess at each evaluation visit after baseline all clinical actinic keratosis lesions' response to the procedure, within the target field, as follows : clear or not completely clear lesion (including new and recurrent lesions).;Primary end point(s): Week 18 | — |
