Filter by:This is a physiopathological case-control, non-interventional, monocentric study of adult patients with lymphangioleiomyomatosis. The controls are patients followed in neurology at the CHU of Tours for a tuberous sclerosis complex without lymphangioleiomyomatosis, the healthy volunteers are women with neither pulmonary nor renal pathology and recruited at the clinical investigation centre of the CHU of Tours.
In this study, subjects with spontaneous or tuberous sclerosis complex associated lymphangioleiomyomatosis (LAM) who have not been started on therapy with mTOR inhibitors such as sirolimus or everolimus to undergo a PET/CT scan using an novel PET tracer that may better evaluate disease activity in LAM subjects both before and after the initiation of mTOR inhibitor therapy will be enrolled. The procedure for each scan will be similar, involving one administration of the novel tracer C11-glutamine followed by a whole body PET/CT scan.
Data from patients with the orphan disease of lymphangioleiomyomatosis (LAM) which performed a pulmonary Rehabilitation program will be analyzed retrospectively. Data will be taken from the internal data base of the reference Center (Schoen Klinik Berchtesgadener Land, Schoenau, Germany) where These data were collected during clinical routine. Data will be included from the year 2000 until now. A retrospectively matched COPD cohort will be included for comparison.
RESULT is a phase II dose-escalating, open-label, safety and efficacy study to determine if there is a potential benefit of resveratrol in combination with sirolimus in patients with lymphangioleiomyomatosis (LAM). The primary study objective is to assess the change in serum vascular endothelial growth factor-D (VEGF-D) level after 24 weeks of treatment with a combination of resveratrol and sirolimus as compared to the VEGF-D level in patients on a stable dose of sirolimus alone. The secondary objectives of this study include an assessment of the safety and adverse effect profile of combined resveratrol and sirolimus in adult patients with LAM, and to determine the effect of treatment with a combination of resveratrol and sirolimus on changes in lung function and quality of life.
This is a phase 1 clinical trial comparing imatinib mesylate to placebo for individuals with lymphangioleiomyomatosis (LAM).
This trial is conducted locally. The aim of this trial is assess the efficacy and a favorable benefit-risk ratio for nintedanib in the treatment of LAM at the dose of 150 mg bid
ECMO(Extracorporeal membrane oxygenation) is being essential for cardiopulmonary failure patients. There are two types of ECMO, which is veno-veno (V-V) that can be used in respiratory failure patients and veno-arterial (V-A) that can be used in cardiac failure patients. V-A ECMO can also be used during lung transplantation, substitution of cardiopulmonary bypass, which can show sufficient performance during operation and better postoperative outcome. However, regarding V-A ECMO circulating from femoral vein to femoral artery, there is a pro blem of differential hypoxia which might influence coronary artery and head vessels. In this prospective study, the investigators are planning to put another ECMO catheter into internal jugular vein which takes a role of left to right shunt, to mitigate the hypoxia of coronary artery.
The investigators will perform a two-center phase I trial of celecoxib (COX-2 inhibitor) administered at 200mg by mouth daily for 6 months. Up to 12 adult women with LAM will be recruited (between 4-8 at each site). The Specific Aims are: Aim 1: To investigate whether, in LAM patients, celecoxib is safe and well tolerated, and has evidence of clinical benefit. Aim 2: To investigate the potential value of a novel biomarker of LAM, quantitative measurement of the number of TSC2 mutant LAM cells per ml of blood, to assess disease severity.
Tuberous Sclerosis Complex (TSC) is a multisystemic autosomal dominant disease that is characterized by the development of benign neoplasms in brain, kidney, lung, skin and heart. TSC is caused by mutations in TSC1 and/or TSC2 genes, which encode, respectively, hamartin and tuberin, that are involved in the regulation of cell proliferation, cell cycle and protein synthesis. Most patients exhibit dermatological, renal, neurological and pulmonary (lymphangioleiomyomatosis, LAM) manifestations. Neurological involvement include subependymal nodules, subependymal giant cell astrocytomas and cortical tubers. LAM is characterized by the proliferation of LAM cells around the airways, blood vessels and lymphatics, which result in vascular and airway obstruction and cyst formation. The most frequent TSC manifestation in the kidney is the development of angiomyolipomas (AML). Dermatologic lesions represent the most common manifestations of TSC, mainly hypomelanotic macules and facial angiofibromas. The most significant functional implication of the tuberin-hamartin complex is its regulatory role upon the mammalian target of rapamycin (mTOR) pathway. Mutations in TSC1 or TSC2 lead to increased mTOR activity and favor tumor development and growth. All lesions associated with TSC, sporadic LAM and sporadic AML share a common molecular pathogenesis, based on TSC1/TSC2 mutations and mTOR hyperactivity. Up to date, TSC patients have been followed in separated medical services in our institution, according to their predominant phenotype. The current knowledge, however, suggest that the ideal follow up of such patients should be conducted in an integrated fashion among the specialties associated with the main disease manifestations. Experts in TSC from each of these areas have recently created a TSC/LAM/AML integrated program in the University of São Paulo Medical Center, and his project will be initiated with the generation of an integrated TSC/LAM/AML registry, which intends not only to clinically characterize this patient population but also to document the employed treatment modalities. Once this first goal is achieved, clinical trials are planned to be performed. The central aim of this observational study is to clinically characterize the TSC/LAM/AML subject population followed and referred to the University of São Paulo Medical Center. Specific aims: To characterize the pulmonary, the neurological, the renal and the dermatologic phenotypes of this patient population.
Lymphangioleiomyomatosis (LAM) is a rare lung disease that mostly affects women of childbearing age. In LAM, abnormal, muscle-like cells begin to grow out of control in the lungs. As a result, air can't move freely in and out of the lungs. In some cases, this means the lungs can't supply the body's other organs with enough oxygen. This study is being conducted to find out what dose of a drug called saracatinib is best tolerated by people with LAM. This drug has been tested in patients with certain types of cancer but is not currently approved by the United States Food and Drug Administration (FDA). Saracatinib may work in cancer by preventing the growth, movement and invasiveness of cancer cells. The use of saracatinib to treat LAM is considered experimental. Preliminary testing already completed suggests that the study drug, saracatinib, may suppress certain substances in the lungs of patients with LAM thus may be effective in slowing down the disease process
