  Purpose

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.

Primary Outcome Measures:
  • To evaluate whether afamelanotide (CUV1647) prevents episodes or reduces the severity of PLE symptoms in patients with a well documented history of PLE [ Time Frame: 18 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the safety and tolerability of afamelanotide (CUV1647) in this specific clinical setting [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • To evaluate the effect of afamelanotide (CUV1647) on melanin density levels as measured by skin reflectance [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • To evaluate whether afamelanotide (CUV1647) has a beneficial effect on the quality of life of patients with a documented history of PLE [ Time Frame: 18 months ] [ Designated as safety issue: No ]
  • To determine if there are other factors that may influence the severity of PLE symptoms eg. sun exposure and use of sun protection methods [ Time Frame: 18 months ] [ Designated as safety issue: No ]

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.

  Eligibility

Ages Eligible for Study:   18 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Patients with moderate/severe polymorphic light eruption (PLE)

Criteria

Inclusion Criteria:

  • Aged 18 - 70 years at inclusion.
  • Well documented history of moderate/severe PLE as diagnosed/confirmed by a photodermatologist or photobiologist. Newly diagnosed patients with moderate/severe PLE can be included if numbers of established patients are limited provided their diagnosis is confirmed by a photodermatologist or photobiologist.
  • Recurrent episodes that occur at least once a year, developing in own country (to exclude patients affected only when traveling to sunnier climates).
  • Have given written informed consent to participate in the study.

Exclusion Criteria:

  • Personal history of melanoma, lentigo maligna or multiple (3 or more) dysplastic nevi.
  • Current Bowen's Disease, basal cell carcinoma, squamous cell carcinoma or other malignant skin lesions.
  • Documented history of other photosensitive conditions.
  • Female who is pregnant (confirmed by positive serum β-HCG pregnancy test prior to baseline) or lactating.
  • Females of child-bearing potential that are not using adequate contraceptive measures.
