PURPOSE Topotecan, administered intravenously, is active in small-cell lung cancer (SCLC). In this study, the comparability of oral topotecan to IV topotecan was investigated. PATIENTS AND METHODS Patients with SCLC that had relapsed 90 days or more after cessation of initial chemotherapy were randomized to receive either oral topotecan (Hycamtin) 2.3(More)
BACKGROUND The Lung Cancer Cetuximab Study is an open-label, randomized phase II pilot study of cisplatin and vinorelbine combined with the epidermal growth factor receptor (EGFR)-targeted monoclonal antibody cetuximab versus cisplatin and vinorelbine alone, in patients with advanced EGFR-expressing, non-small-cell lung cancer (NSCLC). End points of the(More)
BACKGROUND The EGFR T790M mutation is the most common mechanism of drug resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors in patients who have lung cancer with an EGFR mutation (EGFR-mutated lung cancer). In preclinical models, the EGFR inhibitor AZD9291 has been shown to be effective against both EGFR tyrosine kinase(More)
PURPOSE To establish the safety and tolerability of ZD1839 (Iressa), a selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, and to explore its pharmacokinetic and pharmacodynamic effects in patients with selected solid tumor types. PATIENTS AND METHODS This was a phase I dose-escalating trial of oral ZD1839 150 mg/d to a maximum of(More)
UNLABELLED First-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provide significant clinical benefit in patients with advanced EGFR-mutant (EGFRm(+)) non-small cell lung cancer (NSCLC). Patients ultimately develop disease progression, often driven by acquisition of a second T790M EGFR TKI resistance mutation. AZD9291 is a novel oral, potent, and(More)
Circulating tumor cell (CTC) number in metastatic cancer patients yields prognostic information consistent with enhanced cell migration and invasion via loss of adhesion, a feature of epithelial-to-mesenchymal transition (EMT). Tumor cells also invade via collective migration with maintained cell-cell contacts and consistent with this is the circulating(More)
PURPOSE A multicenter phase II study to determine the activity and toxicity of Caelyx (Doxil; Sequus Pharmaceuticals Inc, Menlo Park, CA) in patients with metastatic breast cancer. PATIENTS AND METHODS Seventy-one patients with stage IV breast cancer were treated with Caelyx at doses of 45 to 60 mg/m2 every 3 to 4 weeks for a maximum of six cycles.(More)
INTRODUCTION Epithelial circulating tumor cells (CTCs) are detectable in patients with non-small cell lung cancer (NSCLC). However, epithelial to mesenchymal transition, a widely reported prerequisite for metastasis, may lead to an underestimation of CTC number. We compared directly an epithelial marker-dependent (CellSearch) and a marker-independent(More)
BACKGROUND AND OBJECTIVES Gefitinib (IRESSA, ZD1839), an epidermal growth factor receptor tyrosine kinase inhibitor, has been approved in several countries for the treatment of advanced non-small-cell lung cancer. Preclinical studies were conducted to determine the cytochrome P450 (CYP) isoenzymes involved in the metabolism of gefitinib and to evaluate the(More)
PURPOSE To evaluate tumor response, pharmacodynamic effects, and safety of a combination of lomeguatrib (LM), an O6-methylguanine DNA-methyltransferase (MGMT) inactivator, and temozolomide (TMZ), TMZ alone, and LM/TMZ after disease progression on TMZ alone in patients with advanced melanoma. PATIENTS AND METHODS Patients with unresectable stage III or IV(More)
