PURPOSE Ixabepilone (BMS-247550) is an epothilone B analog that stabilizes microtubules and has antitumor activity in taxane-refractory patients in phase I studies. In a phase II trial, we evaluated the efficacy and safety of ixabepilone in women with metastatic and locally advanced breast cancer. PATIENTS AND METHODS Breast cancer patients with(More)
PURPOSE To evaluate safety and efficacy of trastuzumab with pertuzumab in patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer who had progressive disease on trastuzumab-based therapy. EXPERIMENTAL DESIGN Patients with measurable HER2(+) metastatic breast cancer, < or = 3 trastuzumab-based regimens, and left(More)
During the past decade, cancer stem cells (CSCs) have been increasingly identified in many malignancies. Although the origin and plasticity of these cells remain controversial, tumour heterogeneity and the presence of small populations of cells with stem-like characteristics is established in most malignancies. CSCs display many features of embryonic or(More)
PURPOSE Vascular endothelial growth factor (VEGF) is a potent molecule that mediates tumor angiogenesis primarily through VEGF receptor 2 (VEGFR2). Bevacizumab, a recombinant humanized monoclonal antibody to VEGF, was administered to previously untreated patients to evaluate parameters of angiogenesis. PATIENTS AND METHODS Twenty-one patients with(More)
PURPOSE Ixabepilone is an epothilone B analog that binds to microtubules and results in microtubule stabilization and mitotic arrest. Ixabepilone was evaluated for efficacy and safety in a phase II clinical trial for women with metastatic breast cancer. PATIENTS AND METHODS Patients were eligible if they had not previously received treatment with a taxane(More)
PURPOSE To determine the maximum-tolerated dose (MTD) and toxicity profile of the novel anticancer agent, 2-methoxyestradiol (2ME2) administered orally, in patients with solid tumors. MATERIALS AND METHODS Twenty patients with refractory solid tumors were enrolled. 2ME2 was given orally starting at 400 mg bid with dose escalation until 3000 mg bid. Tumor(More)
P-glycoprotein (Pgp), an ATP-dependent transport protein, confers multidrug resistance in cancer cells. Tariquidar binds and inhibits Pgp. To assess the toxicity, pharmacokinetics (PK), and pharmacodynamics of tariquidar, we conducted a phase I trial of tariquidar in combination with doxorubicin, docetaxel, or vinorelbine in children and adolescents with(More)
PURPOSE We tested the hypothesis that Akt-Ser473 phosphorylation (pAkt) predicts benefit from the sequential addition of paclitaxel to adjuvant doxorubicin plus cyclophosphamide (AC) chemotherapy in patients with node-positive breast cancer participating in the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-28 trial. PATIENTS AND METHODS(More)
PURPOSE The aim of this study was to identify conserved pharmacodynamic and potential predictive biomarkers of response to anti-VEGF therapy using gene expression profiling in preclinical tumor models and in patients. EXPERIMENTAL DESIGN Surrogate markers of VEGF inhibition [VEGF-dependent genes or VEGF-dependent vasculature (VDV)] were identified by(More)
Cancers arising in pancreas, lung, liver and stomach are difficult to treat successfully. Wanting to understand the basis for such intractability, we previously performed comparative analyses of publicly available gene expression data from tumor biopsies. Expression of many cell adhesion genes correlated significantly with intractability of cancers, our(More)
