Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: •Evaluate the impact of afamelanotide on minimal erythema dose (MED) in patients with XPC •Evaluate the impact of afamelanotide on MED in patients with XPV. ;Secondary Objective: •Evaluate the impact of afamelanotide on UV-induced DNA damage and repair capacity in patients with XPC. •Evaluate the impact of afamelanotide on UV-induced DNA damage and repair capacity in patients with XPV. •Evaluate the impact of afamelanotide on melanin density in patients with XPC. •Evaluate the impact of afamelanotide on melanin density in patients with XPV. •Evaluate the safety and tolerability of afamelanotide in patients with XP. •Evaluate the impact of afamelanotide on the skin disease severity of patients with XPC. •Evaluate the impact of afamelanotide on the skin disease severity of patients with XPV. •Evaluate the impact of afamelanotide on the quality of life of patients with XPC. •Evaluate the impact of afamelanotide on the quality of life of patients with XPV;Primary end point(s): The change in MED ;Timepoint(s) of evaluation of this end point: Analysis will compare the individual fold increase in MED from Day 0 to the post-treatment assessment at Day 76. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): •The changes in UV-induced DNA damage and repair capacity from baseline to Day 76, as measured through analysis of UV photoproducts and DNA repair mechanisms on irradiated skin in comparison with non-irradiated skin; •The change in skin disease severity from baseline to Day 70, Day 75 or 76 or Premature Termination Visit (if applicable) and Day 238(±14) as measured by: 5-point IGA scale; 11-point Likert-type scale. •The change in (skin) disease severity from baseline to Day 75 or 76 or Premature Termination Visit (if applicable) and Day 238(±14) as measured by the European XP severity score. •The change in melanin density from baseline to Days 28, 56, 75 or 76 or Premature Termination Visit (if applicable) and Day 238(±14) as measured by spectrophotometry. •The change in Quality of Life from baseline to Days 70, 75 or 76 or Premature Termination Visit (if applicable) and Day 238(±14), as measured by the two instruments: WPAI:GH; XP-derived QOLEB. ;Timepoint(s) of evaluation of this end point: Please see above. | — |
