A Trial of Targeted Therapies for Patients With Slow-Flow or Fast-Flow Vascular Malformations

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) 48 weeks of alpelisib therapy for participants with slow-flow vascular malformations and a gene mutation in one of these signalling pathways (module 1) and (ii) 48 weeks of mirdametinib therapy for participants with fast-flow vascular malformations and a gene mutations in the other signalling pathway (module 2).

24VA021; VATCH Trametinib for Ras/MAPK Pathway VAs

The purpose of this study is to assess the effectiveness and safety of Trametinib (the "Study Drug") in patients with Ras/MAPK pathway driven vascular anomalies (VA). Trametinib has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of metastatic melanoma. Its use in this study is considered experimental because the FDA has not approved the study drug for treating people with VAs. The study will enroll participants 2 months of age up to 30 years of age that have been diagnosed with Ras/MAPK pathway driven vascular anomalies. Study participation will last up to 3 years and will involve regular study visits to Children's Hospital of Philadelphia (CHOP) Philadelphia Campus. Participants will need to take the study drug Trametinib for at least 2 years, or up to 3 years in total, if there is a positive response. Participating in this research means you will attend up to 16 clinic visits. Most visits will take approximately 30 minutes, but some visits will take approximately 2 hours, because you will be asked to complete questionnaires about your experience. Participating in this research also means taking the study drug, having pictures taken, and completing study drug diaries. There is also an optional portion to this study that involves collecting blood for biomarker testing.

24VA022; VATCH Alpelisib for TIE2/PIK3CA Pathway VAs

The study will enroll participants 2 months of age up to 30 years of age. The purpose of this study is to assess the effectiveness and safety of Alpelisib (the "Study Drug") in patients with PIK3CA/TIE-2/TEK pathway driven vascular anomalies (VA). Alpelisib has been approved by the U.S. Food and Drug Administration (FDA) for treating adults and children with certain types of breast cancer. Its use in this study is considered experimental because FDA has not approved the study drug for treating people with VAs. Study participation will last for up to 3 years and will involve regular study visits to Children's Hospital of Philadelphia (CHOP)'s Philadelphia Campus. Participants will need to take the study drug Alpelisib for at least 2 years, or up to 3 years in total if there is a positive response. Participating in this research means you will attend up to 16 clinic visits for the purposes of the study. Most visits will take approximately 30 minutes, but some visits will take approximately 2 hours, because you will be asked to complete questionnaires about your experience. Participating in this research also means taking the study drug, having pictures taken, and completing study drug diaries. There is also an optional portion to this study that involves collecting blood for biomarker testing.

Pregnancy in Women With Rare Multisystemic Vascular Diseases: COGRare5 Study

There are no prospective studies of pregnancies for the diseases studied here in (Heredity Hemorrhagic Telangiectasia, Marfan syndrome or related, primary lower limb lymphedema, superficial arteriovenous malformations, and cerebro-spinal arteriovenous malformations) although complications of these can present life-threatening health problems for the mother and her baby. The purpose of this National prospective study is to obtain greater insight into obstetrical complications associated with rare maternal vascular genetic disorders in order to improve prevention and to reduce risk of death. In this context, experts and patient associations consider that there is a need to make real progress in the formulation of recommendations based on scientific data.

Imaging Lymphatic Function in Normal Subjects and in Persons With Lymphatic Disorders

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).

Identification of Biomarkers for Patients with Vascular Anomalies

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.

A 10-Minute Cardiovascular Magnetic Resonance Protocol for Cardiac Disease

This study aims to identify and assess new CMR techniques that can improve current CMR protocols.
