Clinical Trial 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

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