Brief summary

This is a phase 1 clinical trial comparing imatinib mesylate to placebo for individuals with lymphangioleiomyomatosis (LAM).

Detailed description

This is a double blind, adjusted parallel design, randomized clinical trial comparing imatinib mesylate 400 mg daily or matching placebo on the primary outcome of log transformed serum VEGF-D level in patients with LAM. Sirolimus using patients will have co-administration of Imatinib mesylate or placebo for 28 days prior to sirolimus discontinuation. The duration of 400 mg imatinib mesylate or placebo will be 56 days, a dose reduction is allowed for toxicity. The primary endpoint will be the change in the log transformed VEGF-D one month after monotherapy imatinib mesylate or placebo. Total trial duration is 2 months of drug administration.

Recruitment details

18 Subjects signed consent, 2 subjects failed baseline evaluation and were not randomized. 1 subject was randomized, took 4 placebo pills and stopped (without side effects) and is deemed not evaluable.
