The objective of this phase I study was to determine the maximal tolerated dose (MTD) of erlotinib in patients with recurrent malignant gliomas (MGs) or recurrent meningiomas on enzyme-inducing antiepileptic drugs (EIAEDs). Dose escalation was by a standard 3 x 3 design. The initial starting dose of erlotinib was 150 mg daily. If no dose-limiting toxicity (DLT) was observed, then dose escalatio...

PURPOSE 2-methoxyestradiol (2ME2; Panzem) is an endogenous, estradiol-17beta metabolite that at pharmacologic doses exerts antimitotic and antiangiogenic activities. Studies with a 2ME2 capsule formulation showed limited oral bioavailability. We report the results of a phase I study using a NanoCrystal Dispersion formulation of 2ME2 (2ME2 NCD). EXPERIMENTAL DESIGN Patients with refractory sol...

Phase I trials of anti-cancer therapies aim to identify a maximum tolerated dose (MTD), defined as the dose that causes unacceptable toxicity in a target proportion of patients. Both rule-based and model-based methods have been proposed for MTD recommendation. The escalation with overdose control (EWOC) approach is a model-based design where the dose assigned to the next patient is one that, gi...

BACKGROUND This study evaluated the maximum tolerated dose (MTD) of sunitinib, a multitargeted tyrosine kinase inhibitor, combined with FOLFIRI (irinotecan 180 mg/m2 given over 90 min i.v. and l-leucovorin 200 mg/m2 given over 120 min on day 1, followed by 5-FU 400 mg/m2 bolus and then 2400 mg/m2 infused over 46 h) in untreated metastatic colorectal cancer (mCRC). PATIENTS AND METHODS In this...

Growing evidence has shown that podocyte number is a critical determinant for the development of glomerulosclerosis and progressive renal failure. We previously reported that mitochondrial dysfunction (MtD) is an early event in podocyte injury. Peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) is an important modulator of mitochondrial biogenesis. Here, we investigated the ro...

It has been reported that several naturally occurring and related syn thetic organosulfur compounds exert chemopreventive effects in several target organs in rodent models. The chemopreventive actions of 40 and 80% maximum tolerated doses (MTD) of organosulfur compounds, namely anethole trithione, diali) I disulfide, W-acelylcysteine, and taurine, administered in AIN-76A diet, on azoxymethane (...

Aim: To ascertain the maximum tolerated dose (MTD) and to investigate the acute oral toxic effects of imidacloprid towards Swiss albino male mice. Materials and Methods: The MTD of imidacloprid was determined in pilot dose range finding study following the standard method. Animals were observed for toxic signs and symptoms after oral administration of MTD of imidacloprid in single dose. th The ...

Modern day technology has found its way into every aspect of our lives– be it the server storing our social information, the hand-held smartphones, the home security systems or a remotely monitored pacemaker. Unfortunately, this also increases the opportunity for agents with malicious intent to violate the privacy, availability or integrity of these applications. In fact, with the advancement o...

A recent report shows a correlation of the historical use of thimerosal in therapeutic immunizations with the subsequent development of autism; however, this association remains controversial. Autism occurs approximately four times more frequently in males compared to females; thus, studies of thimerosal toxicity should take into consideration gender-selective effects. The present study was ori...

The primary objective of this 2-part phase 1/2 study was to determine the maximum-tolerated dose (MTD) of the potent and selective Aurora B kinase inhibitor barasertib (AZD1152) in patients with newly diagnosed or relapsed acute myeloid leukemia (AML). Part A determined the MTD of barasertib administered as a continuous 7-day infusion every 21 days. In part B, the efficacy of barasertib was eva...
