Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study objective is to see if IV IgG treatment in Recessive Dystrophic Epidermolysis Bullosa (RDEB) skin in conjunction with VYJUVEK treatment improves wound healing and affects the levels of C7 and HSV-1 antibody levels in serum.

Fewer wounds, more rapidly healing wounds, and decreased C7 and HSV-1 antibodies could improve quality of life.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intra-Personal Control

There is one arm of the study. First, each participant undergoes a 3-month observational period, during which they continue application of their prescribed Vyjuvek. After 3 months, they enter the treatment period, during which they continue their Vyjuvek application and, in addition, receive the IV IgG treatment.
