NCT04128722
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).
NCT05871970
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.
NCT06437158
Bleomycin has nowadays been more and more widely used in the sclerotherapy of LMs, which has been proven to be primarily dose dependent. The investigators aim to compare the efficacy and safety of different concentrations of Bleomycin in the sclerotherapy of LMs for pediatric patients.
NCT06257719
The primary purpose of this study is to retrospectively identify the clinical characteristics of abdominal lymphatic malformations (ALMs) in our single center in China. The second objective of this study is to retrospectively compare the epidemiological features, clinical presentations, cyst properties, surgical treatments, and risk factors for preoperative complications of ALMs between paediatric participants and adult participants.
NCT04994002
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.
NCT01212965
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.
