Lymphangioleiomyomatosis (LAM) is an uncommon disease affecting women. It is associated with cystic lung destruction and progressive respiratory failure. The Multicenter International LAM Efficacy of Sirolimus (MILES) Trial, led by the investigators' research team, demonstrated that mTOR (mammalian target of rapamycin) inhibition with sirolimus was an effective therapy that stabilized decline in FEV1 (forced expiratory volume). However, lung function decline resumed when the drug was stopped at the one year point in MILES, suggesting that therapy is suppressive rather than remission-inducing, and may need to be lifelong. There is therefore a need to understand whether long-term therapy with sirolimus is safe and effective. To accomplish this goal, the investigators will conduct the Multicenter International Durability and Safety of Sirolimus in LAM Trial (MIDAS). This is an observational, real world registry. The investigators propose to enroll 600 LAM patients who are on, have previously failed or been intolerant of or are considering taking sirolimus or everolimus for clinical reasons in a longitudinal observational study. This registry will follow lung function tests and adverse events that are obtained for clinical purposes over periods of at least 2 years. The decision to treat with mTOR inhibitor therapy is made by the clinician and the patient, and will be managed by the participant's clinician. This study will help us to refine treatment for patients with LAM and determine if long term suppressive therapy with sirolimus can prevent progression to later stages of disease. This research will be accomplished as part of the NIH/NCATS Rare Lung Disease Consortium, with data stored and analyzed by the Database Management Coordinating Center (DMCC) at the University of South Florida.
