Primary outcomePrimary: The Change in Disease Severity in Patients With VP as Measured by CGIC. — 2.5 Scores on a scale
Summary
The primary objective is to evaluate the impact of afamelanotide on the severity of skin disease in patients with Variegate Porphyria (VP). The secondary objectives are to evaluate the safety and tolerability of afamelanotide in patients with VP and evaluate the impact of afamelanotide on the quality of life of patients with VP.
