Study of the Disease Process of Lymphangioleiomyomatosis

United States2,000 participantsStarted 1995-12-18

Plain-language summary

Pulmonary lymphangioleiomyomatosis (LAM) is a destructive lung disease typically affecting women of childbearing age. Currently, there is no effective therapy for the disease and the prognosis is poor. This study is designed to determine the disease processes involved at the level of cells and molecules, in order to develop more effective therapy. Researchers intend to identify the proteins and genes that contribute to the process of lung destruction in affected individuals.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

* INCLUSION CRITERIA: General admission criteria for patients include one or both of the following: Findings on lung biopsy diagnostic of LAM; Findings on chest x-ray and/or chest computed axial tomography consistent with LAM. Patients with TSC and pulmonary LAM will be included in the study. Normal non-smokers in the control group are defined as individuals who have not smoked for greater than or equal to 1 year and have no systemic or pulmonary disease. Normal smokers defined as individuals with no systemic or pulmonary disease, who have smoked for greater than or equal to 1 year and have normal chest x-ray and normal pulmonary function tests may be included if needed as controls for a similar population of patients with LAM. Pregnant and or nursing women can be included in accordance with Federal Regulations at Subpart B of 45 CFR 46 Subjects who are pregnant and or nursing will be excluded from procedures during their pregnancy that are greater than minimal risk, until they are no longer pregnant and/or nursing. Procedures that will not be completed while the subject is pregnant and/or nursing including: PFTs, Six Minute Walk Test, thoracentesis, bronchoscopy, and measurements with imaging modalities requiring contrast or with radiation exposure such as Chest x-ray, CT scan, MRI, bone densitometry (DEXA). Allowing subjects to be included in the study may glean important information about individuals with uncommon pulmonary disease during and post pregnancy. EXCLUS…

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
