for COL7
• Devastating, progressive,
painful blistering disease
that often leads to death
• Diagnosed at infancy
• High mortality rate

FCX-007 Providing Hope for RDEB Patients
8
RDEB patients do not produce
type VII collagen (COL7) due to
mutation in COL7A1 gene
Main component of anchoring
fibrils that connect skin layers
FCX-007 is an autologous human
dermal fibroblast transduced with
a lentiviral (LV) vector encoded for
COL7A1
Simple, local injection to the
papillary dermis
9
Detection of COL7 Expression by
Immunofluorescence (Magnification 20x)
• In vitro COL7 expression noted from FCX-007 replicates (red)
• FCX-007 expresses higher levels of COL7 than normal human
dermal fibroblasts (NHDF) as depicted by a brighter signal
• No expression of COL7 in RDEB-positive fibroblasts

• COL7 detected at the basement membrane zone (BMZ; refer to

Immunoprecipitation (IP)/Western Blot
COL7 Formation
Trimeric Form
(900kDa)
• Autologous cells having less rejection risk
• Direct administration of FCX-007 to the upper dermis ensures COL7 is expressed in
the basement membrane zone where anchoring fibrils are formed
• The integrative nature of the lentivirus allows the COL7A1 gene to be passed to
daughter cells as FCX-007 cells divide
• Academic research suggests that in vivo COL7 expression persists for at least one
year in RDEB skin tissue regenerated on immunodeficient mice5
• Even if COL7A1 transgene expression were silenced, COL7 anchoring fibers would
persist, perhaps for years, due to slow turnover rate and long life of molecules6

Long-lasting COL7 Persistence Expected
FCX-007 Phase I/II Clinical Trial Design
12
Title A Phase I/II Trial of FCX-007 (Genetically-Modified Autologous Human Dermal Fibroblasts) for
Recessive Dystrophic Epidermolysis Bullosa (RDEB)
Objectives Primary
1) To evaluate the safety of FCX-007
Secondary
1) To evaluate mechanism of action of FCX-007 at weeks 12, 25, 52 and unscheduled visits through
the evaluation of skin biopsies for COL7 expression and the presence of anchoring fibrils
2) To evaluate the efficacy of FCX-007 through an intra-subject paired analysis of target wound area
at weeks 4, 12, 25, 52 and unscheduled visits, comparing FCX-007 treated wounds to untreated
wounds in Phase I and to wounds administered sterile saline in Phase II through the evaluation
of digital imaging of wounds
Number of
Subjects
Twelve subjects consisting of six adults in the Phase I portion of the trial and, subject to FDA
allowance, six pediatrics in the Phase II portion of the trial
Status Actively recruiting adult subjects
Linear Scleroderma
13
Disease Epidemiology
• Excess production of collagen
I and III characterized by skin
fibrosis and linear scars
• The linear areas of skin
thickening may extend to
underlying tissue and muscle
in children which may impair
growth in affected legs and
arms or forehead
• Lesions appearing across
joints impair motion and may
be permanent
• Localized Scleroderma
~200,000 sufferers US7
comprised of many different
sub-types
Linear Scleroderma
Initial target for FCX-013 is
a group of ~40,000 patients
who have scleroderma over
a major joint and exhibit
severe joint pain8
Current Treatments
Current treatments only
address symptoms:
• Systemic or topical
corticosteroids
• UVA light therapy
• Physical therapy

• Study Design
Bleomycin treated SCID mouse model
N=30 mice over test and control groups
Assessed histologically for reduction of dermal
thickness and sub-dermal muscle in the presence
of FCX-013 and oral ligand
• Result
Bleomycin treatment resulted in skin fibrosis, measured by a significant increase in dermal thickness
Demonstrated that FCX-013 with ligand reduced the dermal thickness of fibrotic tissue to levels
similar to non-bleomycin (saline) with ligand treated skin
Further reduced the thickness of the sub-dermal muscle layer

Non-Modified Cells
• FCX-013 employs Intrexon’s RheoSwitch
Therapeutic System® (RTS®)
The RTS® biologic switch is activated by an orally-
administered activator ligand (AL) that provides the
ability to control level and timing of protein
expression
• Enhances the safety profile of FCX-013 by
providing control over the expression of the
protein
• In vitro studies support RTS® control over FCX-
013 protein expression:
Significant increase in expression of the target
protein in the presence of the AL
In the absence of the AL, the expression is reduced
to normal cellular production of the target protein
Cells transduced with RTS® and off-target gene
construct (RTS-GFP) and non-transduced fibroblasts
(mock) express normal cellular production levels
