BACKGROUND Cholangiocarcinoma (CCA) is clinically heterogeneous; intra and extrahepatic CCA have diverse clinical presentations. Next generation sequencing (NGS) technology may identify the genetic differences between these entities and identify molecular subgroups for targeted therapeutics. METHODS We describe successful NGS-based testing of 75 CCA(More)
Recognition of molecular diversity in disease is required for the development of targeted therapies. We have developed a screening method based on phage display to select peptides recognized by the repertoire of circulating tumor-associated antibodies. Here we isolated peptides recognized by antibodies purified from the serum of prostate cancer patients. We(More)
INTRODUCTION PRONOUNCE compared the efficacy and safety of pemetrexed+carboplatin followed by pemetrexed (Pem+Cb) with paclitaxel+carboplatin+bevacizumab followed by bevacizumab (Pac+Cb+Bev) in patients with advanced nonsquamous non-small-cell lung cancer (NSCLC). METHODS Patients ≥18 years of age with stage IV nonsquamous NSCLC (American Joint Committee(More)
The purpose of this study was to evaluate the feasibility, efficacy, safety, and pharmacokinetics of trastuzumab plus cisplatin and gemcitabine in patients with Her2-overexpressing stages IIIB or IV non-small cell lung cancer (NSCLC) and to study the relationship between results from the two methods for determining levels of Her2 overexpression. Chemonaive(More)
BACKGROUND The primary objectives of this study were to determine the efficacy and tolerability of a pemetrexed-carboplatin combination as first-line therapy in patients with advanced nonsmall cell lung cancer. METHODS Eligibility criteria included Zubrod performance status of 0 or 1, Stage IIIB (malignant effusion) or IV disease, and no prior(More)
BACKGROUND Since PI3K/AKT/mTOR pathway activation diminishes the effects of hormone therapy, combining aromatase inhibitors (anatrozole) with mTOR inhibitors (everolimus) was investigated. PATIENTS AND METHODS We evaluated anastrozole and everolimus in 55 patients with metastatic estrogen (ER) and/or progesterone receptor (PR)-positive breast and(More)
PURPOSE To determine the tolerability and pharmacokinetics of oral CI-1033, a pan-erbB tyrosine kinase inhibitor, administered over 14 consecutive days of a 21-day cycle. DESIGN Phase 1, multicenter trial involving patients with solid tumors that are refractory to standard therapy. CI-1033 was administered initially at 300 mg/day to a minimum cohort of(More)
PURPOSE This study aimed to assess MET amplification among different cancers, association with clinical factors and genetic aberrations and targeted therapy response modifications. EXPERIMENTAL DESIGN From May 2010 to November 2012, samples from patients with advanced tumors referred to the MD Anderson Phase I Clinic were analyzed for MET gene(More)
The identification of new therapeutic uses for existing agents has been proposed as a means to mitigate the escalating cost of drug development. A common approach to such repurposing involves screening libraries of agents for activities against cell lines. In silico methods using knowledge from the biomedical literature have been proposed to constrain the(More)
Background Lenalidomide, an immunomodulatory and anti-angiogenic drug, and temsirolimus, an mTOR inhibitor, have synergistic anti-cancer effects in preclinical models. We conducted a phase I study of the combination in patients with advanced cancers. Patients and methods A “3 + 3” study design was used. During the escalation phase, lenalidomide (orally,(More)
