Active clinical trials for "Lymphatic Abnormalities"

In this study, we investigate the safety and efficacy of topical sirolimus in the treatment of superficial complicated vascular anomolies.

To evaluate the efficacy of Rapamycin in extended cervicofacial lymphatic malformations in pediatric patients. Rapamycin is administered oral for a 6 month period. The success rate is determined by volume reduction superior to 1/5e of the initial volume measured by MRI, impact on QOL and reduction of bleeding in case of mucosal involvement.

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.

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.

Lingual microcystic lymphatic malformations (LMLMs) are rare congenital vascular malformations, presenting as clusters of cysts filled with lymph fluid or blood. They are responsible for a heavy burden even with small well-limited lesions because of oozing, bleeding, infections, or even speech, chewing or breathing impairment. Pain and aesthetic prejudice are also frequently reported. The natural history of LMLMs is progressive worsening. LMLMs complex management requires multidisciplinary care in specialised centres, and the "wait-and-see" approach is frequently used. In complicated lymphatic malformations, whatever the location, treatment with oral sirolimus, an mTOR (mammalian Target of Rapamycin) inhibitor, is often used. Topical sirolimus is a known effective treatment for some cutaneous conditions such as angiofibromas in tuberous sclerosis. Topical applications of sirolimus on the buccal mucosae have been reported in erosive lichen planus and oral pemphigus vulgaris with good tolerance and none to slight detectable blood sirolimus concentrations. The objective of this study is to evaluate the efficacy and safety of a 1mg/mL sirolimus solution applied once daily on mild to moderate lingual microcystic lymphatic malformation in children and adults after 4, 8, 12, 16, 20 and 24 weeks of treatment as compared to usual care (no treatment).

Cutaneous microcystic lymphatic malformations (CMLMs) are rare conditions of children and adults resulting from abnormal embryologic development of lymphatic vessels. They present as clusters of vesicles full of lymph and blood of various extent. They ooze and bleed, inducing maceration, esthetic impairment, scars, pain, bacterial infections and impaired quality of life. Currently, treatments for CMLMs are disappointing, and their management is challenging. Sirolimus is an inhibitor of mammalian target of rapamycin (mTOR), a serine/threonine protein kinase involved in cell growth and proliferation, cellular metabolism, autophagy and angio-lymphangiogenesis. Topical sirolimus, known to be efficient and well tolerated in cutaneous angiofibromas linked to tuberous sclerosis, has recently been reported effective in few reports of patients with CMLMs. The objective of this trial is to compare the efficacy and safety of a 12-week application of 0.1% topical sirolimus versus topical vehicle in CMLMs in children and adults.

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.

Recent studies have demonstrated that growth of vascular malformations can be driven by genetic variants in one of 2 signalling pathways. Targeted drugs specific to these pathways have been developed and shown to be effective in treating cancer. This study will describe the effectiveness of (i) 12 months of alpelisib therapy for participants with slow-flow vascular malformations and a gene mutation in one of these signalling pathways (module 1) and (ii) 12 months of mirdametinib therapy for participants with fast-flow vascular malformations and a gene mutations in the other signalling pathway (module 2).

The main purpose of this study in participants with PIK3CA-mutated lymphatic malformations (LyM) is to assess the change in radiological response and symptom severity upon treatment with alpelisib as compared to placebo.

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.
