Efficacy and safety of everolimus in extrapancreatic neuroendocrine tumor: a comprehensive review of literature
2016
BACKGROUND Everolimus, an oral mTOR (mammalian target of rapamycin) inhibitor, is currently approved for the treatment of progressive pancreatic neuroendocrine tumors (NETs). Although promising, only scattered data, often from nondedicated studies, are available for extrapancreatic NETs. PATIENTS AND METHODS A systematic review of the published data was performed concerning the use of everolimus in extrapancreatic NET, with the aim of summarizing the current knowledge on its efficacy and tolerability. Moreover, the usefulness of everolimus was evaluated according to the different sites of the primary. RESULTS The present study included 22 different publications, including 874 patients and 4…
Preliminary biomarker and pharmacodynamic data from a phase I study of single-agent bispecific antibody T-cell engager GBR 1302 in subjects with HER2…
2018
69 Background: HER2 is overexpressed in many solid tumors and is a validated therapeutic target. GBR 1302 is a HER2xCD3 bispecific antibody engineered (using Glenmark’s BEAT® platform) to direct T-cells to HER2-expressing tumor cells. GBR1302-101 (NCT02829372) is an ongoing, multicenter, open-label, first-in-human study of GBR 1302 in subjects with HER2-positive cancers to evaluate the safety, tolerability, and preliminary efficacy of GBR 1302, and to elucidate the mechanism(s) by which it redirects T-cells to tumor and enhances cytolytic activity of cytotoxic T-cells. Methods: Adults with progressive HER2-positive solid tumors with no available standard or curative treatment receive intra…
A phase II study of the PI3K inhibitor taselisib (GDC-0032) combined with fulvestrant (F) in patients (pts) with HER2-negative (HER2-), hormone recep…
2016
520Background: The PI3K pathway is activated in HR+ BC, often via gain-of-function mutations in PIK3CA that occur in ~40% of HR+ BC. Taselisib is a potent and selective PI3K inhibitor, with greater selectivity against mutant PI3Kα isoforms than wild type (WT) PI3Kα. Phase Ib data demonstrated good tolerability and preliminary efficacy for taselisib + F in HR+ BC. Methods: This Phase II, open-label, single-arm study enrolled post-menopausal pts with HER2-, HR+ locally advanced or metastatic BC (mBC) who had progression or non-response to ≥ 1 prior endocrine therapy in adjuvant or mBC settings. Pts received taselisib (6 mg capsule PO qd) plus F (500 mg IM on Cycle 1 Day 1, Cycle 1 Day 15, the…
Copy number variations inDCC/18q andERBB2/17q are associated with disease-free survival in microsatellite stable colon cancer
2017
We conducted a prospective study to assess the prognostic impact of selected copy number variations (CNVs) in stage II-III microsatellite stable (MSS) colon cancer. A total of 401 patients were included from 01/2004 to 01/2009. The CNVs in 8 selected target genes, DCC/18q, EGFR/7p, TP53/17p, BLK/8p, MYC/8q, APC/5q, ERBB2/17q, and STK6/20q, were detected using a quantitative multiplex polymerase chain reaction of short fluorescent fragment (QMPSF) method. The primary end-point was the impact of the CNVs on the 4-year disease-free survival (DFS). The recurrence rate at 4 years was 20.9%, corresponding to 14% stage II patients vs 31% stage III patients (p<0.0001). The 4-year DFS was significan…
Abstract CT034: A first-in-human phase I/II clinical trial assessing novel mRNA-lipoplex nanoparticles for potent melanoma immunotherapy
2017
Abstract Therapeutic vaccination with tumor antigen-encoding RNAs by local administration is currently being successfully employed in various clinical trials. Advancing from local to more efficient systemic targeting of antigen-presenting cells (APCs), we have developed pioneering RNA-lipoplex (RNA(LIP)) immunotherapeutics for intravenous application based on the employment of well-known lipid carriers without the need for functionalization of particles with molecular ligands. The novel RNA(LIP) formulation has been engineered to preserve RNA integrity after intravenous injection and physicochemically optimized for efficient uptake and expression of the encoded antigen by APCs in various ly…
Pazopanib (GW786034) and cyclophosphamide in patients with platinum-resistant, recurrent, pre-treated ovarian cancer - Results of the PACOVAR-trial.
2017
Abstract Purpose The prognosis is poor for patients with recurrent, platinum-resistant epithelial ovarian cancer (EOC). Evidence suggests that antiangiogenic treatment modalities could play a major role in EOC. A combined therapy consisting of the investigational oral antiangiogenic agent pazopanib and metronomic oral cyclophosphamide may offer a well-tolerable treatment option to patients with recurrent, previously treated EOC. Patients and methods This study was designed as a multicenter phase I trial evaluating the optimal dose as well as activity and tolerability of pazopanib with metronomic cyclophosphamide in the treatment of patients with recurrent, platinum-resistant, previously tre…
Intermittent targeted therapies and stochastic evolution in patients affected by chronic myeloid leukemia
2016
Front line therapy for the treatment of patients affected by chronic myeloid leukemia (CML) is based on the administration of tyrosine kinase inhibitors, namely imatinib or, more recently, axitinib. Although imatinib is highly effective and represents an example of a successful molecular targeted therapy, the appearance of resistance is observed in a proportion of patients, especially those in advanced stages. In this work, we investigate the appearance of resistance in patients affected by CML, by modeling the evolutionary dynamics of cancerous cell populations in a simulated patient treated by an intermittent targeted therapy. We simulate, with the Monte Carlo method, the stochastic evolu…
Update on tolerability and overall survival in COLUMBUS: landmark analysis of a randomised phase 3 trial of encorafenib plus binimetinib vs vemurafen…
2020
Abstract Background BRAF/MEK inhibitor combinations are established treatments for BRAF V600–mutant melanoma based on demonstrated benefits on progression-free survival (PFS) and overall survival (OS). Here, we report an updated analysis of the COLUMBUS (COmbined LGX818 [encorafenib] Used with MEK162 [binimetinib] in BRAF mutant Unresectable Skin cancer) trial with long-term follow-up. Methods In part 1 of the COLUMBUS trial, 577 patients with advanced/metastatic BRAF V600–mutant melanoma, untreated or progressed after first-line immunotherapy, were randomised 1:1:1 to 450 mg of encorafenib QD + 45 mg of binimetinib BID (COMBO450) vs 960 mg of vemurafenib BID (VEM) or 300 mg of encorafenib …
Molecular profile in Paraguayan colorectal cancer patients, towards to a precision medicine strategy
2019
[EN] Somatic mutation analysis and evaluation of microsatellite instability (MSI) have become mandatory for selecting personalized therapy strategies for advanced colorectal cancer and are not available as routine methods in Paraguay. The aims of this study were to analyze the molecular profile as well as the microsatellite status in a series of advanced colorectal patients from two public hospitals from Paraguay, to introduce these methodologies in the routine practice to guide the therapeutic decisions. Thirty-six patients diagnosed with advanced colorectal cancer from two referent public hospitals from Paraguay were recruited from May 2017 to February 2018. Sequenom Mass spectrometry, On…
Associations of Pathogenic Variants in MLH1, MSH2, and MSH6 With Risk of Colorectal Adenomas and Tumors and With Somatic Mutations in Patients With L…
2020
Contains fulltext : 220040.pdf (Publisher’s version ) (Closed access) BACKGROUND & AIMS: Lynch syndrome is caused by variants in DNA mismatch repair (MMR) genes and associated with an increased risk of colorectal cancer (CRC). In patients with Lynch syndrome, CRCs can develop via different pathways. We studied associations between Lynch syndrome-associated variants in MMR genes and risks of adenoma and CRC and somatic mutations in APC and CTNNB1 in tumors in an international cohort of patients. METHODS: We combined clinical and molecular data from 3 studies. We obtained clinical data from 2747 patients with Lynch syndrome associated with variants in MLH1, MSH2, or MSH6 from Germany, the Net…
