Phase 2/3 Clinical Study of QRX003 Lotion in Subjects With Netherton Syndrome

This is a multicenter, open-label study to evaluate the safety, tolerability, and efficacy of 4% QRX003 lotion applied twice daily (BID) for 12 weeks to Netherton syndrome (NS) diseased skin in all affected areas of the body excluding the scalp (the Treatment Area), totaling approximately 50% Body Surface Area (BSA) or more.

A Pilot Study of the Efficacy and Safety of Dupilumab Versus Placebo in Patients With Netherton Syndrome

To date, there are no effective therapy for the management of Netherton Syndrome (NS) Patients use emollients with a limited efficacy on scaling and no efficacy on skin inflammation and pruritus. They may also use topical corticosteroids or calcineurin inhibitors in case of eczematous lesions. The use of therapies targeting skin inflammation has been reported in a few case reports. Their efficacy is very limited and their uses are limited because of the chronicity of the disease, the impaired skin barrier function and the risk for skin infections and skin cancers. Therefore, there is a huge medical need for novel therapies in NS.The expected consequences of this study are that a 16-week course of dupilumab will be more effective than placebo for the treatment of moderate to severe NS Dupilumab could therefore improve skin condition and quality of life.

Clinical Study of QRX003 Lotion in Subjects With Netherton Syndrome

The goal of this clinical trial (via an expanded access Treatment Protocol) is to learn if QRX003 (an investigational drug) applied topically to the skin (including up to the entire body \[except the scalp\]) works to treat the genetic disease Netherton syndrome. It will also learn about the safety of QRX003. The main questions the trial aims to answer are: 1. Does QRX003 impact the clinical presentation of NS in adults and minors by improving the clinical symptoms (diseased skin area, itch, and discomfort; based on clinical scoring, subject self-assessment, and other criteria)? 2. What medical problems do participants have when taking QRX003? 3. What percent of subjects will require rescue therapy? Participants will: Take drug QRX003 twice daily (applied topically to all affected areas of the body excluding the scalp) for 3 months, visit the clinic once every 4-6 weeks for checkups and tests, and to keep a dosing diary that records the times they applied the drug.

Open Label, Safety and Efficacy Study of QRX003 Lotion in Subjects With Netherton Syndrome

To assess the safety, tolerability, and efficacy of QRX003 lotion (4%) when added to standard of care treatment regimen, including systemic therapy in subjects with Netherton syndrome

A Study of the Safety, Tolerability, Pharmacokinetics, and Immunogenicity of BCX17725

This is a first-in-human, Phase 1/1b, 4-part study that includes the evaluation of safety, tolerability, pharmacokinetics (PK), and immunogenicity of BCX17725 when administered via single and multiple doses in healthy adult participants (Parts 1 and 2), and multiple doses in adult participants with Netherton syndrome (Part 3). In Part 4, the effectiveness, safety, and tolerability of BCX17725 when administered via multiple IV and/or SC doses through 12 weeks will be evaluated in adult and adolescent participants with Netherton syndrome.

Evaluation of Topical ATR12-351 in Adults With Netherton Syndrome

The objectives of this clinical trial are to evaluate the safety and tolerability of topically applied ATR12-351, to understand what the body does to ATR12-351, and to observe treatment benefits of the drug in approximately 12 adult patients with Netherton Syndrome (NS). ATR12-351 will be applied to skin lesions on one side of the body, while the vehicle control will be applied to similar lesion on the other side of the body twice daily for 2 weeks.

Study of Skin and Gut Microbiome in a Skin Condition Involving Skin Barrier Impairment and Allergic Symptoms: Netherton Syndrome

It is proposed to conduct an exploratory study to analyze the skin, intestinal, and salivary microbiome, as well as the skin mycobiome and virome, of patients (adolescents and young adults) with Netherton syndrome, a condition characterized by an impaired skin barrier that most likely promotes the development of allergic manifestations. The study will be conducted on patients with Netherton syndrome and control subjects in order to investigate possible correlation factors between the three microbiomes and identify which ones.

Natural History of Netherton Syndrome

The goal of this non-interventional study (NIS) is to collect real-world data to describe the natural history of Netherton Syndrome (NS).

A Study to Explore Safety, Pharmacokinetics, and Early Clinical Signal of Efficacy of DS-2325a in Patients With Netherton Syndrome

Netherton Syndrome (NS) is a severe rare disease characterized by generalized scaling, erythema, and epidermal barrier defects. This study assessed the safety, pharmacokinetics (PK), and efficacy of DS-2325a in patients with NS.

Defining the Skin and Blood Biomarkers of Ichthyosis

Ichthyosis is a group of genetic skin disorders that present with dry, thickened, scaly, or flaky skin. As of today, there is no cure or treatment. Doctors can only treat the dry skin with different types of emollients to soften the scale. A deeper understanding of this disease is required to develop better treatments. There are different types of cells and cell-produced signals (biomarkers) that are being studied in order to help find these new treatments. Looking at biomarkers has been successful in helping us to understand other skin disorders better. The purpose of this study is to determine which blood and skin biomarkers characterize ichthyosis. Hypothesis: We predict that the biomarkers correlating with disease activity in Netherton syndrome will be different than the biomarkers found to correlate with the lamellar and other ichthyosis phenotype.

Clinical Trial Using Humira in Netherton Syndrome

The main objective of this studies therapeutic : to determine the effect of Adalimumab (HumiraR) on clinical inflammatory manifestations of patients with Netherton syndrome after 3 months of treatment , with a post treatment period follow-up of 3 months. Second objectives are To evaluate the safety of Adalimumab in the context of NS To evaluate the improvement of the quality of life at 3 months To evaluate the improvement of pruritus and pain in the patients To study markers of inflammatory and allergy in NS prior and after treatment Benefit of the study An improvement by at least 20% of the cutaneous signs in these patients who suffer from a genetic incurable, chronic, painful and very afflicting disease would be of a great help for these patients. NS is a major source of social exclusion. Risks They are inherent to the risks of biotherapies, especially for an anti-TNF therapy, they comprise a risk of infection. Cutaneous infections occur mainly during infancy, and we have therefore chosen to treat patients over 4 years of age in this study. A close clinical surveillance will be set up (initially every week during the first month of treatment, then every month). This will represents a large number of visits but will provide a high level of security. Benefits/risks ratio In the absence of curative treatment for these patients with a severe genetic skin disease, the benefits/risks ration clearly appears to be in favour of an expected benefit.
