Preclinical studies indicate autophagy inhibition with hydroxychloroquine (HCQ) can augment the efficacy of DNA-damaging therapy. The primary objective of this trial was to determine the maximum tolerated dose (MTD) and efficacy of HCQ in combination with radiation therapy (RT) and temozolomide (TMZ) for newly diagnosed glioblastoma (GB). A 3 + 3 phase I(More)
PURPOSE Novel agents are currently combined with radiation and temozolomide (RT + TMZ) in newly diagnosed glioblastoma using overall survival as the primary end point. Results of these phase II studies are typically compared with the phase III European Organization for Research and Treatment of Cancer (EORTC) survival data that resulted in RT + TMZ becoming(More)
PURPOSE Hyperglycemia has been associated with poor outcomes in many disease states. This retrospective study assessed the association between hyperglycemia and survival in patients with newly diagnosed glioblastoma multiforme (GBM). PATIENTS AND METHODS; Between 1999 and 2004, before the standard use of temozolomide, 191 patients were accrued onto New(More)
PURPOSE Patients with high-grade gliomas (HGG) routinely receive radiation, temozolomide, and glucocorticoids. As each of these is immunosuppressive, we conducted a prospective, multicenter study to follow CD4 counts over time and determine whether low CD4 counts were associated with adverse outcomes. EXPERIMENTAL DESIGN Patients with newly diagnosed HGG(More)
PURPOSE Recent data suggest that the glutamatergic system is important in the proliferation and migration of glioblastoma. Talampanel is a well-tolerated, oral alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor blocker that could be beneficial in this disease. PATIENTS AND METHODS This trial was designed to estimate overall survival(More)
PURPOSE A phase I, dose-finding study of vorinostat in combination with temozolomide (TMZ) was conducted to determine the maximum tolerated dose (MTD), safety, and pharmacokinetics in patients with high-grade glioma (HGG). EXPERIMENTAL DESIGN This phase I, dose-finding, investigational study was conducted in two parts. Part 1 was a dose-escalation study(More)
In a double-blind, single-center, 1-year prospective trial, we compared a pH-dependent Eudragit L-coated formulation of oral 5-aminosalicylic acid (5-ASA) (Claversal), 0.5 g b.i.d., and sulfasalazine (SASP), 1 g b.i.d., in the prophylactic treatment of quiescent ulcerative colitis. Forty-four patients received 5-ASA and 44 received SASP. Clinical,(More)
Various high-performance liquid chromatographic (HPLC) methods for the determination of plasma levels of L-dopa and of its metabolite, 3-O-methyldopa (3-OMD), have been previously described. In this study, we report a modification of these methods, that enables the assay of these two compounds in platelets and plasma obtained from the same sample of whole(More)
The objectives of this study were to determine the safety and efficacy of polyinosinic-polycytidylic acid stabilized with poly-l-lysine and carboxymethylcellulose (poly-ICLC) when added to radiation and temozolomide (TMZ) in adults with newly diagnosed glioblastoma (GB). Patients received external beam radiation with concurrent TMZ (75 mg/m(2)/day) followed(More)
