Phase II trial of the oral mammalian target of rapamycin inhibitor everolimus in relapsed or refractory Waldenstrom macroglobulinemia.

ABSTRACT: PURPOSE The phosphatidylinositol 3-kinase/mammalian target of rapamycin (mTOR) signal transduction pathway controls cell proliferation and survival. Everolimus is an oral agent targeting raptor mTOR (mTORC1). The trial's goal was to determine the antitumor activity and safety of single-agent everolimus in patients with relapsed/refractory Waldenström macroglobulinemia (WM). PATIENTS AND METHODS Eligible patients had measurable disease (immunoglobulin M monoclonal protein > 1,000 mg/dL with > 10% marrow involvement or nodal masses > 2 cm), a platelet count more than 75,000 x 10(6)/L, a neutrophil count more than 1,000 x 10(6)/L, and a creatinine and bilirubin less than 2 x the laboratory upper limit of normal. Patients received everolimus 10 mg orally daily and were evaluated monthly. Tumor
