Condition

Pemphigus Vulgaris (Pv)

Treatment

Filsuvez

Clinical Study ID

NCT06423573
AEB-21
  • All Genders

Study Summary

In patients with epidermolysis bullosa (EB), collagen does not form properly, so their skin is very fragile and blisters easily. Such patients are also at greatly increased risk of developing skin cancers. Filsuvez is a topical gel used to promote healing of skin lesions in patients with certain types of EB. In this observational study, patients with either dystrophic EB (DEB) or junctional EB (JEB) will receive standard of care treatment, whether Filsuvez or something else, and will be followed for up to 5 years. The main purpose is to see if the use of Filsuvez affects the likelihood of developing skin malignancies in these patient populations.

Study Description

Some forms of EB are associated with a greatly increased incidence of aggressive skin and mucosal squamous cell carcinoma (SCC), as well as increased incidence of other skin malignancies including basal cell carcinoma (BCC) and malignant melanoma (MM). This long-term non-interventional study will assess all types of skin malignancies (SCC, BCC, and MM) in DEB and JEB patients. It is an observational study of real-world treatment practices, in which patients will receive standard of care therapy whatever that may entail. Data will be obtained from two sources: clinical study centers in the European Union (EU) and the United Kingdom (UK), and pre-existing EB registries in the EU. Participants will be followed for up to 5 years, and information about the development and nature of skin malignancies will be collected over this time period both from patients who are taking and those who are not taking Filsuvez.
