About this study
Official title: Prospective, Open-label, Uncontrolled Clinical Trial to Assess the Safety and Efficacy of Autologous Cultured Epidermal Grafts Containing Epidermal Stem Cells Genetically Modified With a Gamma-retroviral (rv) Vector Carrying COL17A1 cDNA for Restoration of Epidermis in Patients With Junctional Epidermolysis Bullosa
Prospective open-label, uncontrolled clinical study to assess the safety and efficacy of autologous cultured epidermal grafts containing epidermal stem cells genetically modified with the aid of a gamma-retroviral vector carrying COL17A1 complementary DNA (cDNA) for restoration of the epidermis in patients with junctional epidermolysis bullosa. The purpose of this study is to demonstrate the safety and efficacy after one or more treatments with genetically corrected cultured epidermal autograft (Hologene 17) in patients suffering of junctional epidermolysis bullosa (JEB) with COL17A1 mutation.
Read the detailed description
This is a prospective, open label, uncontrolled clinical trial, phase I/II. Patients will be screened according to the Study Inclusion and Exclusion criteria and will be candidate for the treatment if all inclusion and none of the exclusion criteria are met.
After confirmation of eligibility, patients will undergo biopsy for the collection of the autologous epidermal cells to be used to produce the tissue for the treatment. In case all criteria are met, the transplantation of the new cultured transgenic epidermis will be planned according to the procedures and the need of the patient.
The study treatment consists of a surgical intervention for new restored stem cells implantation.
The surgery will be carried out in 2 stages, the first aims at taking biopsy to isolate epidermal cells including stem cells. The biopsy will be processed in a laboratory of a regenerative medicine manufacturing site where they will be corrected, expanded and prepared as final sheets to be implanted. Therefore, the patient can have his second intervention. In this second surgery, genetically corrected cultured epidermal autograft (Hologene 17) will be implanted into the selected area. The specialist surgeon will either use a local or general anaesthetic for the transplant operation. The treated area will be immobilized for some days after this operation. Antibiotics and anti-inflammatory drugs will be administered (if necessary) to prevent infections and to minimise swelling.
Three months after the transplantation, primary endpoint will be evaluated by the Investigator. The study completion will be reached when 1 year (secondary endpoint) of follow-up after the last transplant in the last patient will be accomplished.
The end of the trial is defined as the last visit of the last patient after the last treatment if any.

Transplantation surgery of genetically corrected cultured epidermal autograft (ATMP)Other
Also called Transplantation of Hologene17 study product (ATMP)
Surgergical procedure for transplantation under anaesthesia of genetically corrected cultured epidermal autograft (Hologene17) on blistering skin areas of JEB patients. By taking some autologous epidermal cells, a new layer of transgenic tissue is grown in the laboratory. This layer of tissue - containing genetically modified stem cells - is then implanted by a surgeon into the damaged area. The implantation can be done in one or more areas and repeated in case of failure of the first surgery.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Transplantation surgery of genetically corrected cultured epidermal autograft (ATMP) in people with Junctional Epidermolysis Bullosa, run by Holostem s.r.l. at 1 site in Austria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 7 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early (reason given: No patient ongoing (none completed the study). Changes to the viral vector ongoing.). Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Safety events (ADRs and SAEs) related to the study treatment (tolerability) (time frame: 3 months after treatment). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Mar 2022.
