Active clinical trials for "Epidermolysis Bullosa Dystrophica"

This study was conducted to assess the safety and efficacy of topical Beremagene Geperpavec (KB103, HSV1-COL7) on DEB patients.

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 investigators also propose optimizing the concentration and manner of delivery of topical gentamicin. The unambiguous milestones will be increased C7 and AFs in the patients' DEJ, improved EB Disease Activity Scores, and absence of significant gentamicin side effects.

The purpose of this trial is to evaluate safety and efficacy of surgical application of EB-101 (autologous, gene-corrected keratinocyte sheets) as a treatment of recessive dystrophic epidermolysis bullosa (RDEB).

Recessive dystrophic epidermolysis bullosa (RDEB) is an incurable, devastating, inherited skin disease for which there is only supportive care. RDEB is due to mutations in COL7A1 gene that encodes for type VII collagen (C7), the major component of anchoring fibrils (AFs) mediating epidermal-dermal adherence. Approximately 20% of COL7A1 mutations are nonsense mutations leading to premature stop codons and a truncated C7 with diminished function. The investigators demonstrated that aminoglycosides such as gentamicin readily induce premature termination codon (PTC) "read through" and produce biologically functional C7 in 22 reported COL7A1 nonsense mutations. Importantly, aminoglycoside-induced C7 reversed the abnormal RDEB cell phenotype and incorporated into the dermal-epidermal junction. Herein, the investigators propose the first clinical trial of gentamicin (topical and intradermal) in RDEB patients with nonsense mutations that the investigators have fully characterized. The milestones include increased C7 and AFs at the patients' dermal-epidermal junction and absence of significant gentamicin side effects.

The purpose of this study is to test the effectiveness of Helicoll (a collagen wound dressing) in treating chronic and non-chronic wounds of recessive dystrophic epidermolysis bullosa (RDEB) patients. Helicoll will be compared to standard wound dressings.

To evaluate the effect of human amniotic membrane as a weekly dressing on chronic wounds in Epidermolysis Bullosa (EB) patients.

Protocol PTR-01-001 is a Phase 1/2 study of PTR-01. The study is divided into an up to 4-week Screening Period, a 10-week Treatment Period and an 8-week Follow-up Period. Cohorts 1, 2, 3 and 4 will consist of 2, 4, 3 and 3 patients respectively. Each cohort will consist of patients divided into two groups (Group 1 and Group 2) randomized in a 1:1 ratio. Patients in Group 1 will receive three doses of active drug followed by 3 doses of saline control. Patients in Group 2 will receive three doses of saline control followed by 3 doses of active drug. Cohort 1 patients randomized to Group 1 will receive 3 doses of active treatment (PTR-01) at a dose of 0.1 mg/kg followed by 3 doses of saline control for a total of 6 doses. Cohort 1 patients randomized to Group 2 will receive 3 doses of saline control followed by 3 doses of active treatment (PTR-01) at a dose of 0.1 mg/kg for a total of 6 doses.

The aim of this clinical trial is to investigate the efficacy (by monitoring overall improvement of EB symptoms) and safety (by monitoring adverse events) of three doses of allo-APZ2-EB administered intravenously to patients with recessive dystrophic epidermolysis bullosa (RDEB).

Protocol PTR-01-002 is a 3-part Phase 2, open-label study of PTR-01. While new patients will be enrolled, priority will be given to patients that satisfactorily completed study PTR-01-001.

This trial will create a skin graft, which the investigators call "LEAES," using the patient's own skin cells that have been genetically engineered in the lab to express a missing protein called type VII collagen. The corrected cells will be transplanted back to the patient.
