Study Details

Study Description

Brief Summary

The CUV156 study will evaluate the safety of afamelanotide in XP-C patients, as well as the drug's ability to assist reparative processes following ultraviolet (UV) provoked DNA damage of the skin. It will assess whether SCENESSE® increases the amount of UV light needed to cause DNA damage of skin cells, as well as the extent of skin repair before and after treatment.

Patients will receive afamelanotide every two weeks for twelve weeks and undergo a follow up visit 6 months later.

Outcome Measures

Primary Outcome Measures

  1. Change in minimal erythema dose (MED). [From Baseline to Day 76.]

    MED is the lowest dose of UV light that causes reddening of the skin.

Secondary Outcome Measures

  1. Change in UV-induced DNA damage and repair capacity. [From Baseline to Day 76.]

    Analysis of UV photoproducts and DNA repair mechanisms.

  2. Change in skin disease severity (A). [From Baseline to Day 238.]

    The higher the score, the more severe the disease.

  3. Change in skin disease severity (B). [From Baseline to Day 238.]

    The higher the score, the more severe the disease.

  4. Change in skin disease severity (C). [From Baseline to Day 238.]

    The higher the score, the more severe the disease.

  5. Change in dermal melanin density. [From Baseline to Day 238.]

    Non-invasive quantitative skin reflectance measurement.

  6. Change in quality of life assessed by a disease specific tool (A) [From Baseline to Day 238.]

    Higher scores represent worse health-related quality of life.

  7. Change in quality of life assessed by a validated global quality of life tool (B) [From Baseline to Day 238.]

    Score calculated in impairment percentages, with higher numbers indicating greater impaired quality of life.
