A Study to Evaluate the Safety and Efficacy of Afamelanotide in Patients With Xeroderma Pigmentosum C and V
Study Details
Study Description
Brief Summary
The CUV152 study will evaluate the safety of afamelanotide in XP-C and XP-V 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.

Outcome Measures
Primary Outcome Measures
- Change in minimal erythema dose (MED) in patients with XP-C. [From baseline to day 76.]
MED is the lowest dose of UV light that causes reddening of the skin.
- Change in MED in patients with XP-V. [From baseline to day 76.]
MED is the lowest dose of UV light that causes reddening of the skin.
Secondary Outcome Measures
- Changes in UV-induced DNA damage, as assessed by quantification of UV photoproduct levels in patients with XP-C. [From baseline to day 76.]
Analysis of UV photoproducts from skin samples.
- Changes in UV-induced DNA damage repair capacity, as assessed by quantification of DNA repair mechanisms in patients with XP-C. [From baseline to day 76.]
Analysis of DNA repair mechanisms from skin samples.
- Changes in UV-induced DNA damage, as assessed by quantification of UV photoproduct levels in patients with XP-V. [From baseline to day 76.]
Analysis of UV photoproducts from skin samples.
- Changes in UV-induced DNA damage repair capacity, as assessed by quantification of DNA repair mechanisms in patients with XP-V. [From baseline to day 76.]
Analysis of DNA repair mechanisms from skin samples.
- Change in skin disease severity in patients with XP-C (A). [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in skin disease severity in patients with XP-V (A) [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in skin disease severity in patients with XP-C (B). [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in skin disease severity in patients with XP-V (B). [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in skin disease severity in patients with XP-C (C). [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in skin disease severity in patients with XP-V (C). [From baseline to day 76.]
The higher the score, the more severe the disease.
- Change in quality of life assessed by a disease specific tool (A) in patients with XP-C. [From baseline to day 76.]
Higher scores represent worse health-related quality of life.
- Change in quality of life assessed by a disease specific tool (A) in patients with XP-V. [From baseline to day 76.]
Higher scores represent worse health-related quality of life.
- Change in quality of life assessed by a validated global quality of life tool (B) in patients with XP-C. [From baseline to day 76.]
Score calculated in impairment percentages, with higher numbers indicating greater impaired quality of life.
- Change in quality of life assessed by a validated global quality of life tool (B) in patients with XP-V. [From baseline to day 76.]
Score calculated in impairment percentages, with higher numbers indicating greater impaired quality of life.
