Trial Outcomes & Findings for A Safety Extension Study in Patients With Erythropoietic Protoporphyria (EPP) (NCT NCT04578496)

NCT ID: NCT04578496

Last Updated: 2020-11-19

Results Overview

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.
