Phase III Trial of CUV1647 in Polymorphic Light Eruption (PLE)

Completed

• Conditions: Polymorphic Light Eruption (PLE)

• Registration Number: NCT00472901
• Lead Sponsor: Clinuvel Pharmaceuticals Limited

Brief Summary

The purpose of this study is to determine whether the afamelanotide (CUV1647) formulation is effective in preventing PLE episodes or reducing the severity of PLE symptoms in patients with a well documented history of the disease. The study also aims to determine whether treatment with afamelanotide (CUV1647) can reduce the use of rescue medication in this group.

Detailed Description

Polymorphic Light Eruption (PLE) is a prevalent photosensitivity disorder, occurring in up to 20% of the European and US populations and up to 5% of the Australian population. The disease is characterised by a rash that is intensely itchy with blisters, bumps and patches presenting on areas of the skin that have been exposed to the sun. There is a lack of effective treatment available for the condition but the most common available forms of therapy include sun avoidance and the use of the use of steroids and/or phototherapy.
