Abstract

BACKGROUND: Lymphangioleiomyomatosis (LAM) is a progressive, cystic lung disease in women; it is associated with inappropriate activation of mammalian target of rapamycin (mTOR) signaling, which regulates cellular growth and lymphangiogenesis. Sirolimus (also called rapamycin) inhibits mTOR and has shown promise in phase 1-2 trials involving patients with LAM. METHODS: We conducted a two-stage trial of sirolimus involving 89 patients with LAM who had moderate lung impairment--a 12-month randomized, double-blind comparison of sirolimus with placebo, followed by a 12-month observation period. The primary end point was the difference between the groups in the rate of change (slope) in forced expiratory volume in 1 second (FEV(1)). RESULTS: During the treatment period, the FEV(1) slope was -12±2 ml per month in the placebo group (43 patients) and 1±2 ml per month in the sirolimus group (46 patients) (P<0.001). The absolute between-group difference in the mean change in FEV(1) during the treatment period was 153 ml, or approximately 11% of the mean FEV(1) at enrollment. As compared with the placebo group, the sirolimus group had improvement from baseline to 12 months in measures of forced vital capacity, functional residual capacity, serum vascular endothelial growth factor D (VEGF-D), and quality of life and functional performance. There was no significant between-group difference in this interval in the change in 6-minute walk distance or diffusing capacity of the lung for carbon monoxide. After discontinuation of sirolimus, the decline in lung function resumed in the sirolimus group and paralleled that in the placebo group. Adverse events were more common with sirolimus, but the frequency of serious adverse events did not differ significantly between the groups. CONCLUSIONS: In patients with LAM, sirolimus stabilized lung function, reduced serum VEGF-D levels, and was associated with a reduction in symptoms and improvement in quality of life. Therapy with sirolimus may be useful in selected patients with LAM. (Funded by the National Institutes of Health and others; MILES ClinicalTrials.gov number, NCT00414648.).

  • Exposure to mTOR inhibitors in the immediate post-transplant period is associated with delayed bronchial anastomotic healing or dehiscence.

    “Although exposure to mTOR inhibitors in the immediate post-transplant period has been associated with delayed bronchial anastomotic healing or anastomotic dehiscence, mTOR inhibitors are now successfully continued up until the time transplant in many centers without complications.(305, 315, 320)”

    The Adverse Events section reports events during sirolimus treatment for lymphangioleiomyomatosis, but does not discuss bronchial anastomotic healing after transplantation. Searches for bronchial anastomotic dehiscence and post-transplant wound-healing complications found no passage addressing the claimed association. Page numbers were not provided in our copy.

    The Study Design describes one year of sirolimus treatment followed by a year without study drug, and the Secondary Analyses mention only two placebo recipients placed on a transplant list. Our copy does not report whether patients continued mTOR inhibitors until transplantation, whether centers followed that practice, or whether it occurred without complications (searched: transplant, sirolimus before transplant, anastomosis).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
