20 Clinical Trials for Various Conditions
Lymphangioleiomyomatosis (LAM) is a rare cystic lung disease that appears to behave like a slowly growing cancer. Since clinical progression is very slow, new blood tests have been used to speed the time required to find safe and effective medications. A large National Institute of Health study called MILES showed that sirolimus (also known as Rapamycin) improved lung function in individuals with LAM. Since most individuals with LAM and impaired lung function are now on sirolimus, future studies may prove more difficult. Laboratory studies suggested that Imatinib mesylate (imatinib), an FDA-approved drug for leukemia, initiates LAM cell death. A pilot trial with imatinib titled "Imatinib Mesylate for the treatment of Lymphangioleiomyomatosis" - (LAMP-1) was funded by the Department of Defense in 2016, and documented (1) the safety of use of tyrosine kinase inhibitors in patients with LAM; (2) the safety of concurrent use of tyrosine kinase and mTOR inhibitors; and, (3) short term variability in vascular endothelial growth factor D (VEGF-D) - a LAM biomarker, as a response to therapies. Due to the short-term LAMP-1 trial, LAMP-2 will be a longer-term 6-month clinical study evaluating the safety and tolerability of imatinib in patients with LAM. Patients that participate in the trial will come in for 5 office visits and check-up phone calls every 2 weeks over the course of 6 months.
This is a study to determine if early, long-term low dose sirolimus is effective for preventing progression to more advanced stages.
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
This is an open label long term follow up study, open to those subjects who were previously enrolled in"RAD001 Therapy of Angiomyolipomata in Patients with Tuberous Sclerosis Complex and Sporadic Lymphangioleiomyomatosis", CCHMC IRB #2008-0812 and who meet the criteria for this long-term follow-up study. The hypothesis is that the drug will inhibit the growth of the angiomyolipomas and possibly even cause regression.
This study will evaluate the safety and efficacy of RAD001 in treating patients with Angiomyolipoma associated with Tuberous Sclerosis Complex or Sporadic Lymphangioleiomyomatosis.
Pulmonary lymphoangioleiomyomatosis (LAM) is a rare destructive lung disease typically affecting women of childbearing age. Currently, there is no effective therapy for the disease and the prognosis is poor. In order to better study this disease, the National Heart, Lung, and Blood Institute (NHLBI) has developed a registry to keep an official record of patients diagnosed with LAM. This research project will collect data from 6 health care centers as well as outside physicians. Researchers hope to provide valuable information about the rate of lung destruction and quality of life in patients with LAM. Patients participating in this study will be followed for 5 years. Tissue collected from these patients may contribute to the development of future studies on the disease processes of LAM.
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.
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.
The purpose of this research study is to see if simvastatin can be taken safely in patients with either LAM or TSC, who are already being treated with everolimus or sirolimus. This is the first step in looking at simvastatin as a drug that may help patients, by impacting the growth and survival of cells that make up the lung lesions that cause problems in LAM and TSC patients. The study also seeks to learn more about how simvastatin works, when given to patients being treated with everolimus or sirolimus, and to evaluate the safety and any potential benefit to patients taking this 2-drug combination. The primary objective of this study is to determine the safety of simvastatin in the treatment of LAM-S or LAM-TS in patients on a stable (for at least 3 months) dose of sirolimus or everolimus. Secondary objectives include: * To assess the effect of simvastatin on forced expiratory volume in 1 second (FEV1). * To assess the effect of simvastatin on forced vital capacity (FVC). * To assess the effect of simvastatin on diffusing lung capacity (DLCO). * To assess the effect of simvastatin on vascular endothelial growth factor -D (VEGF-D) serum levels. * To assess the effect of simvastatin with questionnaire- based assessments of dyspnea, fatigue, and quality of life (QOL). * Assess signs of clinical benefit.
Lymphangioleiomyomatosis (LAM), a disease primarily of women of child-bearing age, is characterized by cystic lung disease and abdominal tumors (e.g., angiomyolipomas). Within the LAM patient population is a subset of patients who develop chylous effusions and lymphangioleiomyomas. Treatment of many of these symptoms has been ineffective. Previous studies with somatostatin and octreotide in other clinical settings have shown reduction in chylous effusions. This study assesses the effectiveness of octreotide in symptomatic patients with LAM, lymphangioleiomyomas and/or chylous effusions/ascites, peripheral lymphedema and chyluria.
This study is an observational registry designed to gather information about Tuberous Sclerosis Complex (TSC) and Lymphangioleiomyomatosis (LAM) in pregnant women and their child.
This study aims to assess \[11C\]acetate positron emission tomography (PET)/computed tomography (CT) as a biomarker for renal angiomyolipomas and pulmonary lymphangioleiomyomatosis (LAM) and an early biomarker of response to rapamycin in LAM patients. \[11C\]Acetate is a radioactive form of acetate, a nutrient commonly processed in our body's cells to generate fat and energy. Preclinical studies support the hypothesis that TSC tumors enhance lipid synthesis compared to normal tissues, suggesting that quantification of \[11C\]acetate in these tumors by PET/CT may provide a metabolic biomarker of disease. Participants in the study will undergo 1 or 2 PET/CT scans over 3 to 6 months at the Massachusetts General Hospital (Boston, MA). \[11C\]acetate is administered through an intravenous catheter. This small amount of radioactivity is short-lived and eliminated from the body within a few hours.
This is a phase 1 clinical trial comparing imatinib mesylate to placebo for individuals with lymphangioleiomyomatosis (LAM).
This study is being done to determine if there is a potential benefit of saracatinib in LAM subjects. Based on the information of this trial, additional clinical development trials will be needed. The study will also test the tolerability of 125 mg of saracatinib given once daily over a 9 month period.
The MIDAS study aims to follow male and female LAM patients who are currently taking, have previously failed or been intolerant of, or may (at some time in the future) take mTOR inhibitors (sirolimus or everolimus) as part of their clinical care. Adult female TSC patients may also enroll, with or without lung cysts.
Specific Aim 1: To investigate whether, in Lymphangioleiomyomatosis (LAM) patients, the combination of sirolimus and hydroxychloroquine is safe and well tolerated Specific Aim 2: To investigate whether, in LAM patients, 6 months of combination therapy with sirolimus and hydroxychloroquine results in improvement of indicators of disease, and whether the gains are sustained after stopping therapy. Specific Aim 3: To investigate the potential role of a LAM-specific peripheral blood signature to predict rates of disease progression and determine responsiveness to combination therapy. This will be a phase I dose escalation study of the combination of sirolimus (2 mg adjusted to keep trough levels between 5-15 ng/ml) and hydroxychloroquine (200 mg or 400 mg) taken orally daily. Up to 18 adult women with LAM will be enrolled.
The purpose of this research study is to find out what effects RAD001 has on angiomyolipomas of a person with Tuberous Sclerosis Complex and to determine the safe dose of RAD001 without toxicity. The hypothesis is that the drug will inhibit the growth of the angiomyolipomas and possibly even cause regression.
The purpose of this study was to determine if rapamycin reduced angiomyolipomata volume in patients with tuberous sclerosis complex or lam.
Lymphangioleiomyomatosis (LAM) is a rare lung disease of women that is caused by genetic mutations. It results in the uncontrolled growth of an unusual type of smooth muscle cell in the lung. These cells invade lung tissue, including the airways, blood vessels, and lymph vessels, and restrict the flow of air, blood, and lymph, respectively. Respiratory failure, lung collapse (pneumothorax), and pleural effusions (chylothorax) are hallmarks of the disease. This study will evaluate the safety and effectiveness of sirolimus, an inhibitor of the mTOR pathway, in stabilizing or improving lung function in people with LAM.
This study will examine the effect of fasting on lymphangioleiomyomas abdominal tumors formed from enlarged lymph nodes containing lymphatic fluid. Previous studies have determined that these tumors increase in size in the evening, but this result could stem from the fact that previous study participants were tested after eating lunch. The purpose of the study is to help researchers understand the factors that produce changes in size of lymphangioleiomyomas, as well as to improve the ability of medical professionals to diagnose lymphangioleiomyomas and avoid confusing these tumors with other malignant tumors. Volunteers must be women who are at least 18 years of age and who have been diagnosed with lymphangioleiomyomas in the abdominal or pelvic areas. Candidates who have had lung or kidney transplants or who have type 1 diabetes will be excluded. Candidates will be screened with a physical examination and medical history. During the study, participants will be admitted to a National Institutes of Health clinical center for three days to undergo a number of tests. Tests will include routine blood and urine tests, and electrocardiogram, research blood testing, and abdominal and pelvic ultrasounds....
