A Study of FCX-007 for Recessive Dystrophic Epidermolysis Bullosa (RDEB)

February 6, 2023 updated by: Castle Creek Biosciences, LLC.

A Phase I/II Study of FCX-007 (Genetically-Modified Autologous Human Dermal Fibroblasts) for Recessive Dystrophic Epidermolysis Bullosa (RDEB)

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).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

7 years and older (ADULT, OLDER_ADULT, CHILD)

Accepts Healthy Volunteers

Design Details

  • Primary Purpose: TREATMENT
  • Allocation: NA
  • Interventional Model: SINGLE_GROUP
  • Masking: NONE

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
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 Names:
  • Genetically-Modified Autologous Human Dermal Fibroblasts

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Adverse Events
Time Frame: 52 weeks post treatment
Number of subjects with adverse events.
52 weeks post treatment

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Complete Wound Closure
Time Frame: Through Week 52
Percentage of target wounds achieving complete wound closure (greater than 90%) at all post-baseline visits
Through Week 52

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
