Brief Summary:
The purpose of this study is to evaluate the safety of FCX-007, evaluate Type VII collagen (COL7) expression and the presence of anchoring fibrils and to analyze wound healing as a result of FCX-007 administration in subjects with recessive dystrophic epidermolysis bullosa (RDEB). Funding Source- FDA OOPD

Condition or disease Intervention/treatment Phase
Epidermolysis Bullosa Dystrophica, Recessive Genetic: FCX-007 Phase 1 Phase 2

Detailed Description:

RDEB is a rare skin and connective tissue disease characterized clinically by skin fragility with easy blistering, erosion and scarring of skin and mucous membranes, and caused by the deficiency of the protein type VII collagen (COL7). The objective of this study is evaluate the safety of FCX-007 intradermal injections in RDEB subjects. Additionally, the trial will evaluate COL7 expression, the presence of anchoring fibrils, as well evidence of wound healing.

Approximately twelve subjects are expected to enroll in the Phase I/II trial. Phase I will enroll approximately six adult subjects. Phase II will enroll approximately six subjects both adults and pediatric (aged seven (7) years or older). All subjects will receive FCX-007 to one or more paired target RDEB wounds. Proof of mechanism will be monitored through digital photography of target wounds and assays conducted on biopsies taken from intact skin sites where FCX-007 is administered.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I/II Study of FCX-007 (Genetically-Modified Autologous Human Dermal Fibroblasts) for Recessive Dystrophic Epidermolysis Bullosa (RDEB)
Actual Study Start Date : July 1, 2016
Actual Primary Completion Date : September 29, 2020
Actual Study Completion Date : April 18, 2022

Arm Intervention/treatment
Experimental: FCX-007

In Phase I, a target of three adult subjects will be enrolled into Group A and a target of three adult subjects will be enrolled into Group B.

In Phase II the study will target enrolling subjects (aged seven (7 years or older) to each arm, but will allow a disproportionate distribution of subjects between Group A and Group B to equal approximately 6 total subjects.

All subjects will receive FCX-007 into one or more paired target wounds as well as to intact skin at least one time during the study with a possible second administration pending laboratory results.

One wound in each target wound pair will be used as control for efficacy and safety evaluations.

Genetic: FCX-007
FCX-007 is a genetically modified cell product obtained from the subject's own skin cells (Autologous fibroblasts). The cells are expanded and genetically modified to produce functional COL7. FCX-007 cell suspension is injected intradermally.
Other Name: Genetically-Modified Autologous Human Dermal Fibroblasts

Primary Outcome Measures :
  1. Adverse Events [ Time Frame: 52 weeks post treatment ]
    Number of subjects with adverse events.

Secondary Outcome Measures :
  1. Complete Wound Closure [ Time Frame: Through Week 52 ]
    Percentage of target wounds achieving complete wound closure (greater than 90%) at all post-baseline visits
