Ramucirumab and its use in gastric cancer treatment

2014

Abstract: The inhibition of the mechanisms of tumor neo-angiogenesis represents a milestone that in the last 10 years has seen the advent of numerous molecules to target action against the vascular endothelial growth factor (VEGF). More recently, new molecules have been developed that inhibit tumor spread by the blockade of specific VEGF receptors (VEGFRs), thereby preventing the binding of a ligand to its receptor and the cascade of proliferative events downstream. Ramucirumab is a fully humanized IgG1 monoclonal antibody that performs its action by blocking the isoform 2 of the VEGF receptor (VEGFR-2). Numerous preclinical and clinical studies have demonstrated its activity in several sol…

Detection of RAS mutations in circulating tumor DNA: a new weapon in an old war against colorectal cancer. A systematic review of literature and meta…

2019

Background: Tissue evaluation for RAS (KRAS or NRAS) gene status in metastatic colorectal cancer (mCRC) patients represent the standard of care to establish the optimal therapeutic strategy. Unfortunately, tissue biopsy is hampered by several critical limitations due to its invasiveness, difficulty to access to disease site, patient’s compliance and, more recently, neoplastic tissue spatial and temporal heterogeneity. Methods: The authors performed a systematic literature review to identify available trials with paired matched tissue and ctDNA RAS gene status evaluation. The authors searched EMBASE, MEDLINE, Cochrane, www.ClinicalTrials.gov , and abstracts from international meetings. In to…

Mitomycin 'C' and vinorelbine as second line chemotherapy for metastatic breast carcinoma

1994

Aims and background Patients with metastatic breast carcinoma resistant to first line chemotherapy may require further treatment. Results o second line chemotherapy are still largerly unsatisfactory. For this reason a phase II study on the combination of mitomycin C and vinorelbine was carried out. Methods Forty patients with anthracycline pretreated metastatic breast cancer were treated with a combination of mitomycin C 10 mg/m2 i.v. on day 1, and vinorelbine 25 mg/m2 i.v. on days 1 and 8. This cycle was repeated every 28 days. Responses were evaluated according to the WHO criteria. Results A major objective response was recorded in 16 cases (40%; 95% confidence limits 32%-48%), with 2 pat…

Treatment of metastatic breast cancer with vinorelbine and docetaxel.

2006

Objective: A phase II study was performed to evaluate efficacy and safety of the combination vinorelbine and docetaxel in patients with metastatic breast cancer previously treated with anthracycline-based regimens. Overall 41 patients were included in the study. Methods: Treatment consisted of vinorelbine 25 mg/m 2 and docetaxel 75 mg/m 2 , both administered on day 1 every 3 weeks for a maximum of 9 cycles. Most patients (92%) were postmenopausal with a median age of 57 years, and median ECOG performance of 1. Sites of disease were viscera in 42% of patients, bones in 30%, soft-tissues in 32%. Sixty-five percent of patients had >2 metastatic sites. Previous treatments included neo-adjuvant …

Cisplatin and epirubicin plus oral lonidamine as first-line treatment for metastatic breast cancer: A phase II study of the Southern Italy Oncology G…

1998

Lonidamine (LND) is a unique antineoplastic drug derived from indazole-3-carboxylic acid which inhibits oxygen consumption and aerobic glycolysis, interfering with energy metabolism of neoplastic cells. LND has been experimentally shown to potentiate the cytotoxic effects of epirubicin (EPI) in human breast cancer cell lines, cisplatin activity in both platinum-sensitive and -resistant human ovarian carcinoma cell lines, and EPI antineoplastic activity in some recent phase III trials carried out in advanced breast cancer. A multicenter phase II trial was carried out with the combination of cisplatin 60 mg/m2, EPI 100 mg/m2 and LND 450 mg/day p.o. in three refracted doses/day starting 2 days…

A phase I/II trial of non-pegylated liposomal doxorubicin, docetaxel and trastuzumab as first-line treatment in HER-2-positive locally advanced or me…

2011

Abstract Aim To assess the activity and safety of non-pegylated liposomal doxorubicin (Myocet®) in combination with docetaxel and trastuzumab as first-line treatment of patients with HER-2/neu-positive metastatic breast cancer (MBC). Patients and methods The maximum tolerated dose of the combination was defined in the phase I part of the study. In the phase II part, 45 HER-2/neu-positive MBC patients were enrolled to receive 6–8 cycles of Myocet® 50 mg/m2 (day 1), docetaxel 30 mg/m2 (days 2 and 9) plus trastuzumab (day 2, 4 mg/kg followed by 2 mg/kg/week) every 21 d until unacceptable toxicity or progression occurred. Objective response (primary end-point) and treatment tolerability were as…

“Weekly docetaxel and gemcitabine as first line treatment for metastatic breast cancer: results of a multicenter phase II study”

2004

<i>Objectives:</i> We conducted a multicenter phase II study to evaluate the clinical efficacy, toxicity, and dose intensity of a new weekly schedule of docetaxel and gemcitabine as first-line treatment of metastatic breast cancer patients. <i>Methods:</i> We enrolled 58 patients, 52% of whom had received a previous anthracycline-containing chemotherapy. The treatment schedule was: docetaxel 35 mg/m<sup>2</sup> and gemcitabine 800 mg/m<sup>2</sup> i.v. on days 1, 8, 15 every 28 days. <i>Results:</i> All patients were assessable for toxicity and 56 for efficacy. Overall response rate was 64.3% with 16.1% of complete responses and 48…

Cigarette smoking habit does not reduce the benefit from first line trastuzumab-based treatment in advanced breast cancer patients.

2011

Many ErbB2-positive cancers may show intrinsic resistance, and the frequent development of acquired resistance to ErbB-targeted agents represents a substantial clinical problem. The constitutive NF-κB activation in some HER-2/neu positive breast cancer may represent a potential cause of resistance to trastuzumab therapy. Preclinical data revealed that 4-(N-Methyl-N- nitrosamino)-1-(3-pyridyl)-1-butanone (NNK), the tobacco-specific nitrosamine is able to enhance NF-κB DNA binding activity and theoretically to increase the resistance to trastuzumab. Two hundred and forty-eight women with pathologically confirmed, uni- or bidimensionally measurable, HER-2-positive metastatic breast cancer (MBC…

An open-label, randomized phase II study of adecatumumab, a fully human anti-EpCAM antibody, as monotherapy in patients with metastatic breast cancer

2009

Background: High-level expression of epithelial cell adhesion molecule (EpCAM) is associated with unfavorable prognosis in breast cancer. This study was designed to investigate two doses of the fully human IgG1 anti-EpCAM antibody adecatumumab (MT201) in patients with metastatic breast cancer (MBC). Methods: A total of 109 patients were stratified into high- and low-level EpCAM expression by immunohistochemical staining of primary tumors and subsequently randomly assigned to receive monotherapy with either high- (6 mg/kg every two weeks (q2w)) or low-dose adecatumumab (2 mg/kg/ q2w) until disease progression. Results: No complete or partial tumor responses could be confirmed by central RECI…
