Filter by:Hereditary epidermolysis bullosa (HEB) is a heterogeneous group of rare genetic diseases, characterized by fragility of the skin and mucous membranes, which results in the appearance of mucocutaneous bullae and erosions during minimal trauma. Pruritus is a neuropathic pain mainly related to activation of unmyelinated cutaneous C nerve fibers and is very common in patients with HEB. It is the cause of trophic disorders, aggravation of certain wounds, appearance of new bubbles. In addition, this chronic pruritus can also have a major psychological impact on the patient and his family. However, these therapies used in the pruritus of patients with HEB have often proven to be ineffective. In order to improve the quality of life of children and their families, research into new therapies to limit this chronic pruritus is necessary. Among phytocannabinoids, CANNABIDIOL (CBD) should be clearly distinguished from Delta-9-tetrahydrocannabinol (THC). Indeed, CBD is an "inverse" agonist of the CB2 receptor, it acts by reducing the effect of this receptor, while THC is an agonist of the CB1 and CB2 receptors. Thus, CBD has antipsychotic, anxiolytic, antiemetic, anti-inflammatory and anti-epileptic effects, unlike THC which has psychotic, relaxation effects, impairs cognitive function and memory. Cannabinoids are involved in the physiopathology in pruritus at the level of the peripheral nervous system via the CB1 and TRPV1 receptors, and also at the level of the central nervous system thanks to the CB1 and CB2 receptors. In addition, inflammation plays an important role in the physiopathology of pruritus and this is reduced via the activation of CB2 receptors, expressed in immune cells. Various studies with promising results have examined the effect of cannabinoids in pruritus. No serious adverse effects have been reported and the rare adverse effects that have been observed are reversible upon discontinuation of treatment. The research project seeks to estimate the efficacy of CANNABIDIOL in the pruritus of 10 children with severe hereditary epidermolysis bullosa. Pruritus is assessed before the start of treatment, then after one month of taking oral treatment, three times a day. The effectiveness of taking the treatment will also be assessed on pain, on the impact on sleep and on overall quality of life. The tolerance of CANNABIDIOL will be well monitored. The systemic passage of CANNABIDIOL is measured during a routine blood test 1 month after treatment.
This is a three-part, Phase I, first-in-human study designed to evaluate the safety, tolerability, and potential systemic exposure of multiple topical doses of TCP-25. Part I includes healthy volunteers with acute epidermal wounds formed by the suction blister technique. Part II includes patients with non-healing leg ulcers and Part III patients with dystrophic epidermolysis bullosa (DEB).
A sub-set of patients who participated in PTR-01-002 will be enrolled in an open-label study, if they meet the study eligibility criteria.
TolaSure is a topical gel for the promotion of accelerated wound healing. This Phase I study will assess the safety, tolerability, and clinical effects of TolaSure when applied to wounded skin areas of patients diagnosed with severe epidermolysis bullosa simplex (i.e., EBS-Dowling Meara). A total of 10, severe EBS patients, males and females ages 18 years and older, will be enrolled. Patients will apply TolaSure and Vehicle Gel once-daily for a maximum of 10 weeks.
This is a 112-week (approximately two-year) open-label extension study of Beremagene Geperpavec (B-VEC), for participants aged 2 months and older, who have been diagnosed with Dystrophic Epidermolysis Bullosa (DEB). Participants will be dosed weekly with the topical B-VEC therapy. The primary endpoint will be to assess long term safety and tolerability of the topical gene therapy. The study is for those who participated in Phase 3 study, as well as, new participants who were unable to participate in the Phase 3 study, who meet all enrollment criteria.
The purpose of this study is to evaluate the safety of INM-755 (cannabinol) cream and obtain preliminary evidence of efficacy in treating symptoms and healing wounds over a 28-day period in patients with epidermolysis bullosa (EB).
Hereditary epidermolysis bullosa (HEB) are rare genodermatoses, clinically characterized by epithelial and subepithelial fragility leading to the formation of blisters and spontaneous erosions on skin at the slightest contact, with possible mucosal damage. The care of these patients consists of therapeutic baths leading to renew bandages that sometimes covering the entire integument. These are difficult, delicate and painful moments that patients experience daily at home. For an unexplained reason for 70 to 80% of them, the weak or strong opioid analgesics, deemed necessary and prescribed for good pain control, are not taken on a regular basis as a premedication for baths and dressing changes. The aim of the study is to understand the child's brakes on taking weak or strong opioid analgesics at the time of care and the parents' difficulties in giving these treatments by means of individual interviews.
The overall purpose of this study is to address whether topical gentamicin therapy is an effective and feasible treatment. Specifically, we will investigate the effect of non-intensive treatment (once daily or every other day) on skin protein expression, as well as quantify the effect on wound healing in patients with EB caused by PSC (part A). Furthermore, we will address in vitro whether gentamicin restores protein expression of genes affected by SSM in fibroblasts derived from skin biopsies obtained from patients with EB caused by SSM (part B). If these in vitro experiments yield positive results, the patients donating the cells will be offered to enter part A of this study. The overall duration of part A in this study is planned to be 18 weeks per patients and consists of a 6 weeks treatment period followed by a 12 week follow up period. Each patient will attend 3 study visits: at week 0, week 6 and week 18. All patients will be included within a time period of 12 months. The overall duration of part B will be up to 8 weeks per patients of which 4-7 weeks are spent to prepare fibroblasts obtained from skin biopsies. Then 5 days of in vitro intervention and subsequent analysis follows. Altogether, the duration of the GENTELBULL study will be 78 weeks or less.
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.
Previously, many studies have been conducted on mesenchymal stem cells derived from bone marrow or subcutaneous fat, but interest in cord blood-derived mesenchymal stem cell treatments has been increasing recently. In the case of cord blood as a source, the isolation of mesenchymal stem cells is easier than bone marrow or fat tissue, and cord blood-derived mesenchymal stem cells have an advantage as a treatment because they have faster population doubling time. To date, no clinical research on the treatment of patients using cord blood-derived mesenchymal stem cells has been reported in the literature, but there have already been registered at clinicaltrials.gov and currently being conducted overseas. In this study, we will study the safety and effectiveness of RDEB patient treatment using cord blood-derived mesenchymal stem cells with these advantages.
