Summary

The purpose of this study is to determine if treatment with PLX3397 and Sirolimus will be tolerated and result in shrinking of the cancer or stopping the cancer from growing. In the phase I portion, the maximum tolerate dose of the study drug will be determined. In the Phase II portion, progression free survival will be assessed at the dose level found in Phase I. Participants will continue to take the study drug until they experience an unacceptable side effect or their disease progresses. Funding Source - FDA OOPD

Interventions

DRUG

PLX3397

PLX3397 is a small molecule that potently and selectively inhibits macrophage colony-stimulating factor receptor (FMS), Kit, and FMS-like tyrosine kinase 3 (Flt3)-internal tandem duplication (ITD) kinases, which regulate key components of the tumor microenvironment and oncogenic variants of these kinases that drive certain tumors.

DRUG

sirolimus

Sirolimus is a macrocyclic lactone that binds to tacrolimus (FK506) binding protein 12 and inhibits mammalian target of rapamycin (mTOR) resulting in cell-cycle arrest and apoptosis. Sirolimus is currently approved as an immunosuppressive agent for organ transplantation and more recently, as a component of cardiac arterial stents because of its potent antiproliferative effects on fibroblasts responsible for restenosis after such a procedure (26) Sirolimus is commonly administered orally on a daily basis, in doses ranging from 2 to 40 mg/day.
