Active clinical trials for "Epidermolysis Bullosa Dystrophica"

After confirming eligibility, a single subject with four selected target lesions will receive both ALLO-ASC-SHEET and Vehicle control, three target lesions for ALLO-ASC-SHEET and the other target for Vehicle control, and which lesion to apply which IP treatment will be determined randomly at the time of enrollment using pre-designed block randomization scheme.

Recessive dystrophic epidermolysis bullosa (RDEB) is an incurable, devastating, inherited skin disease caused by mutations in the COL7A1 gene that encodes for type VII collagen (C7), the major component of anchoring fibrils (AFs), structures that mediate epidermal-dermal adherence. Thirty percent of RDEB patients have nonsense mutations. The investigators recently demonstrated in 5 such patients that intradermal and topical gentamicin induced "read-through" of their nonsense mutations and created robust and sustained new C7 and AFs at the dermal-epidermal junction (DEJ) of their skin and also stimulated wound closure and reduced new blister formation. No untoward side effects occurred. Herein, the investigators propose evaluating the safety and efficacy of intravenous gentamicin in these patients. In theory, this intravenous administration has the possibility of treating simultaneously all of the patients' skin wounds. The milestones will be increased C7 and AFs in the patients' DEJ, improved EB Disease Activity Scores, and absence of gentamicin side effects.

To evaluate and further characterize the safety of EB-101 (LZRSECol7A1 Engineered Autologous Epidermal Sheets [LEAES]) for the treatment of RDEB wounds in new and previously EB-101 treated patients 6 years and older.

Epidermolysis bullosa (EB) is a heritable skin disease characterized by marked fragility of epithelialized tissue with blistering in skin and mucous membranes following the slightest mechanical trauma. Eighty percent of all patients suffering from recessive dystrophic EB (RDEB), a subtype originating from mutations in the COL7A1 gene, develop squamous cell carcinoma (SCC). In RDEB patients SCC presents early (most patients are in their 20s or 30s) and shows a highly aggressive metastatic course which often leads to premature death at this young age. In light of scarce data on the efficacy and safety of systemic treatment regimens for advanced SCC, the investigators propose to perform a small, "first in EB " trial of an experimental drug called rigosertib for the treatment of EB cancer. The trial will be conducted in two study centres, in London and Salzburg, and will last approximately 2.5 years with each patient recruited being in the study for 1 year. The drug is a polo-like kinase inhibitor interfering with different molecular pathways that are essential for cancer cell growth. Rigosertib was developed by Onconova Therapeutics and is currently tested in several clinical trials for a number of other cancers including myelodysplastic syndrome (a cancer of the blood). The investigators have identified that rigosertib most selectively kills EB cancer cells in vitro while leaving normal EB skin cells unaffected. This project will evaluate whether rigosertib is capable of inducing an anti-cancer response in EB patients and whether the drug is well-tolerated. Mechanisms of molecular targeting of squamous cancer cells by rigosertib will further be investigated in EB patients, also aiming at the identification of biomarkers that may allow the predictive identification of best responders.

This pilot trial studies how rigsertib sodium works in treating patients with Recessive Dystrophic Epidermolysis bullosa (RDEB) with locally advanced Squamous Cell Carcinoma (SCC). Rigosertib may selectively target Epidermolysis bullosa (EB) cancer cells while leaving normal EB cells unaffected.

The purpose of this study is to determine whether administration of FCX-007 in addition to standard of care improves wound healing as compared to standard of care alone (control) in children, adolescents, and adults with Recessive Dystrophic Epidermolysis Bullosa. Funding Source - FDA OOPD

This phase I/II clinical trial aims to treat 3 adult subjects with Recessive Dystrophic Epidermolysis Bullosa, expressing residual C7 levels, by genetically corrected autologous skin equivalent grafts on selected areas (up to 300 cm2).

Single patient study. Patient diagnosed with dystrophic epidermolysis bullosa presenting chronic open wounds that are not responding to dressings, topical preparations (antimicrobials, antibiotics) and systemic agents (anti-inflammatory antibacterials). The Self-Assembled Skin Substitutes will be used to cover wounds.

The study will compare gene expression differences between blistered and non-blistered skin from individuals with all subtypes of EB, as well as normal skin from non-EB subjects. State of the art computational analysis will be performed to help identify new drugs that might help all EB wound healing and reduce pain. Researchers will focus on drugs that have already been approved for treatment of other dermatologic or non-dermatologic diseases, and therefore be repurposed for treatment of EB. Drug development is a very expensive process taking decades for execution. Drug repurposing on the other hand, significantly reduces the cost and shortens the amount of time that is needed to bring effective treatments to clinical use. To date, there is no specific treatment targeting the physiology and immunologic response in EB patients during wound healing. Market availability of repurposed medications will provide all EB patients rapid access to treatments, thus improving their quality of life.

INVESTIGATIONAL PRODUCT: AGLE-102 is an allogeneic derived extracellular vesicle (EV) product derived from normal donor mesenchymal stem cells (MSCs). INDICATION AND RATIONALE: The aim of the study is to assess the safety and efficacy of AGLE-102 in the treatment of lesions in subjects with Epidermolysis Bullosa (EB). STUDY DESIGN: This is a phase 1/2A, non randomized, multi-center, ascending dose, study to assess the effectiveness and safety of AGLE-102 on lesions in subjects with EB.
