Filter by:The study aimed to assess the long-term safety of topical use of Zorblisa (SD-101-6.0) in participants with Epidermolysis Bullosa (EB).
Our goal is to determine whether daily oral administration of VPD-737 (5 mg) is effective and safe in treating moderate to severe pruritus in patients with Epidermolysis Bullosa (EB).
Adult participants will apply a broccoli sprout extract-jojoba oil compound to one arm every night under occlusion for 1 week. Jojoba oil alone will be applied to the other arm. At the end of 1 week, a 6mm punch biopsy will be taken from both arms and analyzed via polymerase chain reaction (PCR) and immunohistochemistry for differences in various skin proteins.
This is a single-institution, phase II study to determine the event-free survival at 1 year post allogeneic transplant and serial mesenchymal stem cell (MSC) infusions from a related donor (HLA identical, mismatched or haploidentical) or matched unrelated donor for the biochemical correction of severe epidermolysis bullosa (EB).
This is a phase I/II open-label study to evaluate the efficacy and safety of ALLO-ASC-DFU in patients with Dystrophic Epidermolysis Bullosa.
Recessive dystrophic epidermolysis bullosa (RDEB) is a severe form of blistering skin disease caused by mutations in COL7A1 gene. This study aims to assess the safety of intradermal injections of gene-modified autologous fibroblasts in 5-10 adults with RDEB.
Epidermolysis bullosa simplex type Dowling-Meara (EBS-DM) is one of the most severe subtypes of EBS. Blisters and erosions of the skin and mucous membranes upon minor trauma are the consequence of dominantly inherited mutations in either the keratin 5 (K5) or keratin 14 (K14) gene, which encode proteins constituting the intermediate filament (IF) network in basal keratinocytes . Autosomal dominant mutations lead to a conformational change and an increased self-aggregation of the protein. Upon stress, aggregates present in the periphery of the cytoplasm, subsequently leading to the disintegration and collapse of the IF network. Clinically, patients suffer from blistering of the skin and mucous membranes upon minor trauma, resulting in an impaired life quality due to pain and pruritus . In vitro studies on Dowling-Meara keratinocytes revealed a significant upregulation of the pro-inflammatory cytokine interleukin-1beta (IL-1ß). Apart from paracrine effects of IL-1ß upon wounding (e.g. attraction of lymphocytes, activation of dermal fibroblasts), IL-1ß also activates keratinocytes via the cjun N-terminal kinase (JNK) stress pathway. The activation of this pathway leads to the activation of a number of transcription factors and the enhanced transcription of a number of genes, like matrix metalloproteinases, kallikreins, but also IL-1ß itself and K14 . Interestingly, this state of activation is constitutive and was also found in keratinocytes from non-lesional sites. It seems that the upregulation of IL-1ß and K14 in the presence of dominant Dowling-Meara mutations, results in a positive feedback loop, potentially aggravating the EBS-DM phenotype. This was strongly corroborated by the fact that when impairing IL1ß signaling, using IL-1ß neutralizing antibody (IL-1Ab) or the small molecule diacerein, expression levels of IL-1ß and K14 decreased and keratinocytes were much less susceptible to heat shock in vitro . Furthermore, activation levels of JNK widely correlated with expression levels of K14 and IL-1ß. (Wally V et al, 2013). These findings led to the hypothesis that blocking IL-1ß will also lead to an amelioration of the EBSDM phenotype in effected patients. Based on previous in vitro findings diacerein was chosen to be topically applied in a pilot study with five patients suffering from EBS-DM. In that study , each participant received 1% diacerein-cream for one armpit, and placebo for the other (randomized withdrawal). The number of blisters was reduced significantly (left: -78%; right: -66% of baseline) within two weeks and remained significantly below the initial level even during withdrawal in four patients. These findings pointed to a relevant effect of diacerein and provide important information for our confirmative study. Diacerein is a component of the rhubarb root, which is reported to block the release of active IL-1b by inhibiting plasma membrane-bound IL-1 converting enzyme . Diacerien is already approved for systemic application in osteoarthritis . In general, small molecules (SM) are low molecular weight compounds with biological functions that can influence molecular processes. They allow a symptomatic treatment, offering a short-term benefit for patients in terms of an amelioration of the phenotype. Although this kind of treatment does not correct genetic alterations, it can still be highly beneficial by damping down disease symptoms, thereby increasing life quality and minimizing secondary manifestations. It is important to emphasize that besides dressings, there are currently no other treatments, therefore, investigators do not prevent an accepted treatment for the patient and there is no risk for the participant. The treatment will be given only to the armpits although the disease can involve other areas, so stopping dressings in the armpits during the study does not risk the patient. Should there be any deterioration of the patient, whether it is related to the treatment with diacerein or not, investigators will stop the use of diacerein.
The aim was to assess the efficacy and safety of SD-101-6.0 cream versus Placebo (SD-101-0.0) cream in the treatment of skin lesions in participants with Epidermolysis Bullosa. Funding Source - United States Food and Drug Administration (FDA) Office of Orphan Products Development (OOPD).
To assess whether intravenously administered third-party bone marrow-derived mesenchymal stromal cells (MSCs) are safe and have an impact on disease severity in RDEB
Skin wounds of Recessive Epidermolysis Bullosa Dystrophica (REBD) involve pain, superinfection, protein-losing, inflammation, and joint contractures are the bed of squamous cell carcinoma. There is no precise data on the kinetics of healing post-bullous erosions but clinical experience suggests that most epidermise in less than a month. Some, however, for unknown reasons, persist for several months. These chronic ulcers (UC), arbitrarily defined for this study as lasting more than three months are a source of major discomfort and could play a decisive role in the morbidity and mortality of the disease. The aim of this study is to evaluate the efficacy of the amniotic membrane on the healing of chronic ulcers REBD on the percentage ulcerated surface re-epithelialised at 12 weeks (M3) from the start of treatment.
