  Purpose
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.

Detailed Description:

Tuberous sclerosis complex (TSC) is an autosomal dominant disorder caused by mutations in tuberous sclerosis complex 1 (TSC1) or TSC2 tumor suppressor genes. TSC is characterized by tumors in a wide range of tissues, seizures, mental retardation, autism, and organ failure. Lymphangioleiomyomatosis (LAM), the major pulmonary manifestation in women with TSC, is a progressive lung disease characterized by infiltration of atypical smooth muscle like cells (TSC-/- LAM cells) and formation of parenchymal cysts. Sporadic LAM can develop in women who do not meet the criteria for the diagnosis of TSC, owing to somatic mutations in the TSC2 gene.

The long term goal of this research is to devise novel therapeutic strategies for patients with LAM. The observed behavior of LAM cells with respect to their infiltrative growth pattern, metastatic potential, and altered cell differentiation is reminiscent of cells undergoing epithelial-mesenchymal transition (EMT). Src kinases are key regulators of cellular proliferation, motility, invasiveness and EMT. Recent results have shown that autophagy promotes degradation of active Src. Thereby, decreased autophagy due to mTOR activation known to occur in LAM cells, may play a significant role in accumulation of active Src in these cells. Src suppresses transcription of E-cadherin by upregulating its transcriptional repressors. The preliminary data reveal an increase in active Src in lung tissues of patients with LAM as well as in cultured TSC2-/- cells. Further, in TSC2-/- cells, E-cadherin is considerably reduced and does not localize to the plasma membrane, as it does in wild-type cells.

The focus of this study is to examine if Src inhibition represents a potential therapeutic strategy in LAM. It is proposed that Src activation in TSC2-/- cells results in the reduction of E-cadherin, loss of cell-cell adhesion and elevation of oncogenic and metastatic potential of these cells. The increased Src activity in TSC2-/- cells is likely caused by inhibition of autophagy associated with hyper-activation of mTOR. Therefore, the use of Src inhibitors may lead to a reduction in tumor growth and prevent dissemination of TSC2-/- cells. In this study, the investigators will evaluate the safety and efficacy of Src inhibition in subjects with LAM.

A number of inhibitors of Src are now in clinical trials in patients with a range of different tumors. Dasatinib, an oral adenosine triphosphate (ATP)-competitive Src inhibitor, is now approved for clinical use in patients with chronic myeloid leukemia or acute lymphoblastic leukemia. However, dasatinib has wider 'off target' inhibitory activity than saracatinib including potent activity against Abl, ephrin receptor kinases, platelet-derived growth factor receptor and c-KIT (type of receptor tyrosine kinase and a type of tumor marker. Also called CD117 and stem cell factor receptor.) In contrast, saracatinib has a >10-fold preference for Src over Abl kinases and has very little activity against other tyrosine and serine/threonine kinases. Saracatinib has been already characterized in multiple clinical trials in terms of safety and pharmacokinetics.

The investigators have conducted a Phase1b study to test the safety of various doses of Saracatinib in LAM subjects. The purpose of the Phase1b trial was to determine the optimal dose in terms of safety and tolerability in LAM population. Three escalating doses of saracatinib; 50, 125 and 175 mg were studied. Saracatinib was given orally once a day. Overall, subjects tolerated Saracatinib well. The investigators chose the dose of 125 mg to conduct further testing of both safety and efficacy in this Phase 2a trial.
