22 Clinical Trials for Various Conditions
Background: The lymphatic system is a network of vessels that carry a clear fluid called lymph through the body. Problems in the lymphatic system can cause pain, fluid buildup, and issues with immunity. There is much researchers do not understand about lymphatic anomalies. In this natural history study, they will collect data from a lot of people over a long time. Objective: To better understand why lymphatic anomalies develop. The goal is to improve future treatments. Eligibility: People aged 0 days and older with a suspected or confirmed lymphatic anomaly. Their unaffected parents or siblings aged 7 years or older are also needed. Design: Participants may remain in the study indefinitely. Affected participants may be evaluated every 10 months to 2 years. Some participants will be seen over telemedicine. Others will be seen at the NIH Clinical Center for 2-5 days. All participants will have a physical exam. They may provide specimens including blood, saliva, hair follicles, stool, skin, and other tissues. Samples may be used for genetic testing. Participants may undergo other tests depending on their medical conditions. The NIH Clinical Center visit may include: Heart tests include placing stickers on the chest to measure electrical activity and using sound waves to capture pictures of the heart. A lung test measures the muscle strength in the chest. Participants will blow into a tube. Photographs may be taken of participants faces and other features. Imaging scans will take pictures of the inside of the body. One scan will measure bone density. One type of scan tracks how lymph fluid moves through the body. Participants will be under anesthesia, and they will be injected with a dye.
Lymphatic Anomalies (LA) is characterized by proliferation of lymphatic tissue causing deterioration of pulmonary function. Understanding changes in lymphatic anatomy in these patients is hindered by the difficulty of imaging the lymphatic system. Dynamic Contrast Enhanced MR Lymphangiogram (DCMRL) may be useful in investigating pathological changes in the lymphatic system.
Lymphatic anomalies are a rare subset of vascular anomalies that are poorly understood. the understanding of the natural history, long-term outcomes, risk factors for morbidity and mortality, and the relative benefit of medical therapies and procedures is limited.The goal of this project is to better understand these diseases and improve the care of theses rare patients. To do this, the investigators are conducting an observational study of patients with lymphatic anomalies, including an annual follow-up questionnaire to gather prospective data on mortality, morbidity, treatments, and functionality as well as quality of life.
SELVA: A Multicenter, Phase 3 Baseline-Controlled Study Evaluating the Safety and Efficacy of QTORIN 3.9% Rapamycin Anhydrous Gel in the Treatment of Microcystic Lymphatic Malformations The main purpose of this study is to assess the change in microcystic lymphatic malformations IGA after 24 weeks of treatment with QTORIN 3.9% Rapamycin Anhydrous Gel in approximately 40 participants with microcystic lymphatic malformations. Efficacy will be evaluated at 24 weeks and patients have the option of continuing on treatment for \>24 weeks.
This is a Phase 2a/b single arm open label study to evaluate the safety, reactogenicity, and efficacy of intracystic injection of TARA-002 in participants 6 months to less than 18 years of age for the treatment of macrocystic and mixed cystic lymphatic malformations. The Phase 2a safety lead-in, age de-escalation study is designed to establish the safety of TARA-002 in older participants 6 years to less than 18 years before proceeding to younger participants 2 years to less than 6 years, then 6 months to less than 2 years. The Phase 2b is an expansion study in which enrollment of participants will be initiated after safety has been established in each cohort during the Phase 2a safety lead-in study. Each participant will receive up to 4 injections of TARA-002 spaced approximately 6 weeks apart.
This study evaluates the safety and efficacy of PTX-022 (sirolimus) Topical Gel 3.9% w/w in the treatment of Microcystic Lymphatic Malformations. The participant will receive 3 months of PTX-022 treatment by the end of the study.
The primary objective of this study is to evaluate the safety and tolerability of CERC-006 in adults (aged 18-31 years) with active, moderate to severe complex lymphatic malformations.
In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.
The purpose of this research is to gather information on the safety and effectiveness of core biopsy of vascular anomalies for clinical pathology and clinical genomics studies.
VT30-101 is a 2-part first-in-human trial of topically administered VT30 to subjects with cutaneous venous malformations, lymphatic malformations, or mixed venolymphatic malformations associated with PIK3CA or TEK mutations. Part 1 is a 4-week treatment, open-label, 4-sequence, escalating repeat-application cohort study, with intra-subject and inter-cohort dose escalation. Part 2 is a 12-week treatment, randomized, placebo-controlled, double-blind, safety and exploratory efficacy study. Part 2 will be initiated only after the successful completion of Part 1 with results that demonstrate the general safety and tolerability of topically applied VT30. Up to 12 subjects who complete Part 1 may be enrolled into Part 2 of the study. The primary objective is to evaluate the safety and tolerability of VT30. The study will also determine the dose and regimen of VT30 to be carried into Part 2 of the protocol. Other aims include documenting plasma drug levels of VT30 and VT10 and, on an exploratory basis, examining pharmacologic target engagement and change in potential efficacy readouts.
The study will use blood (serum and plasma) and tissue obtained from participants undergoing prescribed surgical resection of vascular anomalies of interest proposed in this study. The study will also use blood (serum and plasma) and tissue collected and stored in a tissue bank maintained by the Department of Hematology/Oncology.
The purpose of this study is to determine if the use of sirolimus in the treatment of children and young adults with complicated vascular anomalies will prove to be safe and provide objective response resulting in improved clinical status and quality of life.

The main purpose of this study in participants with PIK3CA-mutated LyM is to assess the change in radiological response and symptom severity upon treatment with alpelisib film-coated tablets (FCT) as compared to placebo.
There is an unsatisfied medical need for a first-line treatment of lymphatic malformations with a good benefit/risk profile. Based on a patient experience in the institution, the investigators plan to verify whether or not the medication sildenafil has a beneficial effect on lymphatic malformations. The investigators plan to do this by treating patients with lymphatic malformations with the medication sildenafil for a 20 week period. This is an investigator initiated study funded by an Innovations in Patient Care grant and a SPARK grant.
PURPOSE The purpose of this study is to learn more about multifocal lymphangioendotheliomatosis with thrombocytopenia (MLT). MLT is a rare vascular disorder characterized by multiple congenital skin and visceral lesions, profound thrombocytopenia, and gastrointestinal bleeding. The skin lesions may appear red, brown or blue, often misdiagnosed as hemangiomas. The gastrointestinal tract, liver, and lungs are the most common internal organs involved. The severe thrombocytopenia (low platelets) is believed to be the result of platelet trapping within the skin and visceral vascular lesions. Severe and chronic gastrointestinal bleeding is common during infancy and early childhood. Although a relatively newly described entity, MLT was likely previously reported as hemangiomas, blue rubber bleb nevus syndrome, diffuse hemangiomatosis, Kasabach-Merritt phenomenon, and hereditary hemorrhagic telangiectasia. The term cutaneovisceral angiomatosis with thrombocytopenia is also a term used for this same disease. This study is a longitudinal cohort study of MLT to collect detailed clinical data on the distribution of disease, disease severity, and complications. This data will be used to create diagnostic criteria and an evaluation protocol for infants with this disease
3 patients were enrolled in each of 3 study cohorts. There three cohorts were given differing, incrementally larger doses of this phase I drug. The same safety measures are being obtained on all patients. Efficacy measures were individualized as enrolllees do not have the same underlying vascular anomaly. The study is structured to include a 24 month drug-phase and a 24 month follow-up phase. The study is now closed to enrollment.
Background: - Lymphatics are a type of vessel, similar to arteries and veins. Lymphatic disorders happen when these vessels don t work properly. Researchers want to look for a relationship between lymphatic disorders and variations of certain genes found in the lung, blood, and other places in the body. Objective: - To learn more about lymphatic disorders and evaluate how genetic factors affect lymphatic disorders. Eligibility: * People ages 2 90 who have a lymphatic disorder or relatives of people with lymphatic disorders. * Healthy volunteers 18 and older. Design: * Participants may have 1 2 visits a year, or more as needed. The study is expected to last 5 years. Visits may last 1 5 days. Participants may have lab tests, medical history, and physical exam at each visit. * Participants may have blood testing that includes genetics tests, and urine tests. They may have nose and throat cultures, saliva collection, and cheek swabs to collect samples. * Participants may have a skin biopsy and have blood taken from an artery. * Participants may have breathing tests and be studied while exercising. * Participants may have an electrocardiogram. Electrodes will be placed on their chest, tracing heart rhythms. They may also have chest X-rays. * Participants may have a bronchoscopy. A thin, flexible instrument will be passed through the nose or mouth, into the lung. A tissue sample will be taken. * Participants who have lymphatic disease or have a relative with it may also have: * CT scans. They will lie on a table and hold their breath while their chest is scanned. * MRI. They will lie flat on a table that slides in and out of a scanner. * ultrasound. A probe is rolled around outside the abdomen. * removal of fluid around the lungs, chest, and abdomen.
The purpose of the International Lymphatic Disease and Lymphedema Patient Registry and Biorepository is to collect health information in order to study the disease classification, natural history, and impact of Lymphatic Disease, Lymphedema and Related Disorders and its treatments and medical outcomes.
The purpose of this study is to demonstrate the feasibility of near-infrared fluorescence imaging in subjects with acquired or hereditary lymphedema, in subjects with lipidema and other lymphovascular disorders and in normal health subjects; in order to attempt to correlate imaging phenotype(s) with genotype(s).
This is a 3-part Phase 2 randomized study evaluating the safety and efficacy of the mutant-selective PI3Kα inhibitor, RLY-2608, in adults and children with PIK3CA Related Overgrowth Spectrum (PROS) and malformations driven by PIK3CA mutation. Part 1 is a dose selection, Part 2 is a basket design with exploratory single-arm cohorts for various subpopulations of participants, and Part 3 is randomized, double-blinded study vs placebo.
This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.
The purpose of this research study is to evaluate the safety of the drug Etanercept (Enbrel) and to determine if this drug can help in the treatment of early bone marrow failure in patients with Fanconi anemia.
