简要总结
The purpose of this study is to determine whether administration of D-Fi in addition to standard of care improves wound healing as compared to standard of care alone (control) in children, adolescents, and adults with Dystrophic Epidermolysis Bullosa.
详细描述
CCB-EB-304 is a multi-center, intra-patient randomized and controlled, open-label, rater-blinded Phase 3 study of D-Fi for the treatment of persistent non-healing and recurrent DEB wounds in approximately 32 subjects. Each subject will serve as his/her own control. Each subject's Target Wounds will be paired then randomized to receive D-Fi (Treatment Wound) or remain untreated (Control Wound). One Target Wound Pair will be identified for each subject.
Subjects will receive intradermal injections of D-Fi in each specified Treatment Wound in three or more treatment sessions. The first treatment session occurs at Day 1, the second at Week 8/Month 2 and the third at Week 16/Month 4. Additional treatment sessions may occur at Week 26/Month 6 and Week 32/Month 8 and Week 40/Month 10 when unclosed Treatment Wounds may be re-treated, and unclosed Control Wounds may be treated. Safety and efficacy assessments will occur at scheduled intervals through Week 48/Month 12, when the Treatment Period is completed, and is followed by an optional Open-Label Extension (OLE) treatment phase of an additional 96 weeks. A long-term safety follow-up period (through 15 years) commences for subjects who have received one or more D-Fi injections, either following the treatment phase or if the subject had opted-in, the OLE.

研究组 & 干预措施
D-Fi COL7A1 Genetically-Corrected Autologous Fibroblasts
Intra-subject randomized (paired wounds in each subject receive experimental treatment, D-Fi, or remain untreated). One target wound pair will be identified for each subject. Following pairing, target wounds will be randomly assigned as the treatment wound (D-Fi is administered) or control wound. Subjects will receive intradermal injections of D-Fi in each specified treatment wound in two or more treatment sessions. The first treatment session occurs at Day 1, the second at Week 8/Month 2 and the third at Week 16/Month 4. Additional treatment sessions may occur at Week 26/Month 6, Week 32/Month 8 and Week 40/Month 10 when unclosed treatment wounds may be re-treated, and unclosed control wounds may be treated.
干预措施: D-Fi (Biological)
