A Safety Extension Study in Patients With Erythropoietic Protoporphyria (EPP)
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The main objectives of the study were to evaluate the safety and tolerability of afamelanotide by measuring treatment emergent adverse events (AEs) and to determine whether afamelanotide can improve the quality of life of EPP patients.
Change in Quality of Life Measured Using the EPP-quality of Life Questionnaire (EPP-QoL). [ Time Frame: Baseline, Day 60, Day 120, Day 180 or early termination (ET) (if applicable) ]
The EPP-QoL is presented as 15 questions aiming at measuring how the condition has affected the patient over the last 2 months. Each question is answered on a categorical scale. The maximum score is calculated by summing the score of each question resulting in a maximum of 100 and a minimum of 0. The higher the score, the better the quality of life.
Change in Quality of Life Measured Using the Dermatology Life Quality Index Questionnaire (DLQI) [ Time Frame: Baseline, Day 60, Day 120, Day 180 or early termination (ET) (if applicable) ]
The DLQI questionnaire consists of 10 questions, each answered on a categorical scale. The DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired.
