Filter by:The primary objective of the study is to determine the effect of pozelimab on active CD55-deficient protein-losing enteropathy (PLE; CHAPLE). The secondary objectives of the study are: - To evaluate the safety and tolerability of pozelimab in patients with CD55-deficient PLE disease - To evaluate the effect of pozelimab on CD55-deficient PLE (both patients with active disease at baseline and those with inactive disease on eculizumab, switching to pozelimab) - To determine the effects of pozelimab on albumin and other serum proteins (total protein, immunoglobulins) - To determine the effects of pozelimab on ascites - To determine the effects of pozelimab on stool consistency - To determine the effect of pozelimab on health-related quality of life - To determine the effect of pozelimab on lab abnormalities observed in CD55-deficient PLE such as hypertriglyceridemia, thrombocytosis, and hypovitaminosis B12 - To describe the effects of pozelimab on the sparing of concomitant medications and reduction in hospitalization days - To determine the effects of pozelimab on growth - To characterize the concentration of pozelimab in patients with CD55-deficient PLE - To assess the incidence of treatment-emergent ADA for pozelimab in patients with CD55-deficient PLE disease
The Fontan procedure has revolutionized the treatment of patients born with a congenital univentricular heart defect. However, over time, it is associated with severe lymphatic complications such as plastic bronchitis, protein-losing enteropathy (PLE) and peripheral edema. The hypothesis is that patients with a univentricular circulation have a changed morphology which may be associated with both the degree of lymphatic complications and their physical capacity. The morphology will be described using T2-weighted non-contrast MRI.
Plastic bronchitis (PB) is a rare, most often pediatric disease characterized by the formation of obstructive airway casts primarily composed of fibrin. There is presently no FDA-approved pharmacotherapy for PB, but acute exacerbations of the illness are often treated with inhaled tissue plasminogen activator (tPA). To date, this is done somewhat anecdotally because there has been no safety or efficacy testing of this treatment. In addition, there is presently no reliable surrogate marker of adverse drug events. Nevertheless, in the absence of inhaled tPA treatment, PB-induced respiratory distress can be severe, often warranting urgent or emergent bronchoscopy for cast removal, or can sometimes result in respiratory failure. As such there is a significant unmet need for safety and efficacy testing of inhaled tPA and for biomarkers of drug response. Objectives and Endpoints: The objectives of this protocol are to: 1) test the safety and efficacy of an inhaled tPA regimen in children with PB; and 2) identify potential candidate biomarkers of inhaled tPA drug response. Safety endpoints will consist of the development of new, active bleeding that is systemic and/or pulmonary and/or new hematuria (defined as gross hematuria). Secondary endpoints of efficacy will also be measured (e.g., frequency of cast production). Urine and blood will also be collected for the development of potential biomarkers of inhaled tPA drug response. Funding source- FDA OOPD
The investigators are studying what causes Plastic Bronchitis and Protein Losing Enteropathy. The investigators think that these problems are from too much of two small proteins called Vasoactive Intestinal Peptide (VIP) and Substance P. VIP and Substance P are important proteins in the body that normally tell the body to make small amounts of fluid and they help the intestines work. Normally, VIP and Substance P are made in the intestines and then destroyed in the lungs after they do their normal work. The investigators think that kids who have Plastic Bronchitis and/or Protein Losing Enteropathy who also had the Fontan surgery might have too much VIP and Substance P in their bodies. The investigators think this causes too much fluid to go in the lungs and too much protein in the intestines.
