This clinical trial is focused on studying two rare conditions: Erythropoietic Protoporphyria (EPP) and X-Linked Protoporphyria (XLP). These are genetic disorders that cause sensitivity to sunlight, leading to painful skin reactions. The study is testing a medication called Dersimelagon, also known by its code name MT-7117. This medication is taken orally in the form of a tablet.
The purpose of the study is to evaluate the long-term safety and tolerability of Dersimelagon in individuals with EPP or XLP. Participants in the study will take the medication over an extended period, and their health will be monitored to ensure the treatment is safe and well-tolerated. The study will involve regular check-ups, including physical exams and laboratory tests, to track any changes in health and to identify any potential side effects.
Throughout the study, participants will be closely observed for any treatment-emergent adverse events, which are any new or worsening health issues that occur during the study. This includes serious adverse events and any other health concerns that may arise. The study aims to provide valuable information on the long-term use of Dersimelagon for managing EPP and XLP, contributing to better understanding and treatment of these conditions.
