Active clinical trials for "Lymphangioma"

Overgrowth syndromes are rare genetic disorders defined by tissue hypertrophy that can be either localized or generalized, affecting both latitudinal and longitudinal growth. The genes involved in overgrowth syndromes are not well characterized but mostly concern the PIK3CA/AKT/mTOR pathway, a major actor of cell growth and proliferation. The mutations are not inherited but occurs during embryogenesis leading to somatic mosaicism. Owing to the variability of the clinical presentation, their exact prevalence is yet unknown. In order to answer this question, the investigators team create here the first French national registry on overgrowth syndromes.

The investigators propose a pilot trial to obtain preliminary information regarding the safety and response rate of patients with symptomatic lymphatic malformations treated with oral Selenium. Information obtained in this pilot trial will be used to plan future phase 2 clinical trials. Hypotheses: Selenium will be safe and efficacious in the treatment of adolescents and young adults with symptomatic lymphatic malformations Disease response will correlate with serum levels of selenium and blood levels of antioxidants essential to selenium metabolism.

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.

OBJECTIVES: I. Determine the efficacy of picibanil sclerotherapy in children with macrocystic lymphangioma.

Standard of care for Lymphatic Malformations has been surgical excision. We have been using OK432/Picibanil (generously supplied by Chugai Pharmaceuticals in Japan) since 1992 with great success for macrocystic disease. The objective of the study was to provide OK-432 immunotherapy to subjects with macrocystic or mixed (> 50% macrocystic) lymphatic malformations (LMs) and investigate the efficacy and safety of OK 432 as a treatment option in subjects with LMs.

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.

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.

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.

A Phase 2 study to evaluate safety and efficacy of sildenafil taken orally to improve or resolve lymphatic malformations in children. Subjects may receive either placebo or treatment in an oral dosage with an open label extension for subjects who received placebo. The study treatment assignment will be randomized in a double blind fashion. MRI examination will evaluate change in lesion volume due to treatment. Other safety and efficacy measures will be taken through the 32-week study duration. Funding Source - FDA OOPD

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.
