  Purpose

The purpose of this study is to determine whether afamelanotide (CUV1647) is effective in reducing the number of actinic keratoses and squamous cell carcinomas developing in immune compromised organ transplant recipients, who are at particularly high risk, over a 24 month test period.

The number of lesions formed on the head, hands and forarms will be monitored over this 24 month test period.

Primary Outcome Measures:
  • To determine the effect of afamelanotide (CUV1647) administered from slow release subcutaneous implants on the number of actinic keratoses (AKs) on the head, forearms and back of hands [ Time Frame: 24 months ]

Secondary Outcome Measures:
  • To determine and compare the proportion of patients in each group that develops one or more squamous cell carcinoma (SCC) [ Time Frame: 24 months ]
  • To examine the effect of ongoing sun exposure on lesion formation and progression in the patient group [ Time Frame: 24 months ]
  • To evaluate the safety and tolerability of multiple slow release subcutaneous implants of afamelanotide (CUV1647) [ Time Frame: 24 months ]
