This study describes, for the first time, the development and validation of a highly selective and sensitive heterogeneous fluoroimmunoassay (FIA) for the bioanalysis of two monoclonal antibodies (mAbs) used for cancer immunotherapy: bevacizumab (BEV) and cetuximab (CET). The assay combines reliable non-competitive binding of BEV and CET to their specific cell receptor proteins (human vascular endothelial growth factor (VEGF) and epidermal growth factor receptor (EGFR), respectively) with the highly specific fluorescence activity of the fluorescein isothiocyanate labeled anti-human IgG (FITC-IgG) used as label...

Epidermal Growth Factor Receptor (EGFR)-dependent signaling plays a crucial role in epithelial cancer biology, and dictated the development of several targeting agents. The mouse-human chimeric antibody Cetuximab was among the first to be developed. After about two decades of clinical research it has gained a significant place in the management of advanced colorectal and head and neck cancers, whereas its development in non small cell lung cancer (NSCLC) has not led to a place in routine clinical practice, because of marginal clinical benefit despite statistically significant Phase III trials...

BACKGROUND: Pretargeting-based approaches are being investigated for radioimmunoimaging and therapy applications to reduce the effective radiation burden to the patient. To date, only a few studies have used short-lived radioisotopes for pretargeting of antibodies, and such examples with internalizing antibodies are even rarer. Herein, we have investigated pretargeting methodology using inverse electron-demand Diels-Alder (IEDDA) for tracing two clinically relevant, internalizing monoclonal antibodies, cetuximab and trastuzumab...

Epidermal growth factor receptor (EGFR), upregulated in gastric cancer patients, is an oncogene of interest in the development of targeted cancer nanomedicines. This study demonstrates in silico modeling of monoclonal antibody cetuximab (CET MAb)-conjugated docetaxel (DOCT)-loaded poly(γ-glutamic acid) (γ-PGA) nanoparticles (Nps) and evaluates the in vitro/in vivo effects on EGFR-overexpressing gastric cancer cells (MKN-28). Nontargeted DOCT-γ-PGA Nps (NT Nps: 110±40 nm) and targeted CET MAb-DOCT-γ-PGA Nps (T Nps: 200±20 nm) were prepared using ionic gelation followed by 1-Ethyl-3-(3-dimethyl aminopropyl)carbodiimide-N-Hydoxysuccinimide (EDC-NSH) chemistry...

Anti-idiotypic binders which specifically recognize the variable region of monoclonal antibodies have proven to be robust tools for pharmacokinetic studies of antibody therapeutics and for the development of cancer vaccines. In the present investigation, we focused on the identification of anti-idiotypic, shark-derived IgNAR antibody variable domains (vNARs) targeting the therapeutic antibodies matuzumab and cetuximab for the purpose of developing specific capturing ligands. Using yeast surface display and semi-synthetic, CDR3-randomized libraries, we identified several highly specific binders targeting both therapeutic antibodies in their corresponding variable region, without applying any counter selections during screening...

BACKGROUND: The survival of colorectal cancer patients is frequently determined by the extent of metastatic invasion to the liver; in cases of major involvement, therapeutic strategies are limited because the liver is necessary for drug metabolism. MATERIAL AND METHODS: We have reviewed articles about the pharmacokinetic profiles of each drug used in colorectal cancer patients with hepatic dysfunction to determine which of these treatments are most feasible. RESULTS: Some drugs appear to be feasible options for patients with hepatic insufficiency...

Administration of first-in-class anti-EGFR monoclonal antibody cetuximab is contingent upon extensive pharmacogenomic testing. However in addition to tumor genomics, drug exposure levels could play a critical, yet largely underestimated role, because several reports have demonstrated that cetuximab pharmacokinetic parameters, in particular clearance values, were associated with survival in patients. Here, we have developed an original bioanalytical method based upon the use of LC-MS/MS technology and a simplified sample preparation procedure to assay cetuximab in plasma samples from patients, thus meeting the requirements of standard Therapeutic Drug Monitoring in routine clinical practice...

The combination of hepatic artery infusion (HAI) of irinotecan, 5-fluorouracil and oxaliplatin with intravenous cetuximab has safely achieved prolonged survival in colorectal cancer patients with extensive liver metastases and prior treatment. Systemic exposure to the drugs or their main metabolites was determined during the first course of chronomodulated triplet HAI in 11 patients and related to toxicities after one or three courses. Consistent trends were found between the area under the plasma concentration-time curve (AUC) values of irinotecan, 7-ethyl-10-hydroxycamptothecin (SN38; a bioactive metabolite), total oxaliplatin and platinum ultrafiltrate (P-UF), on the one hand, and subsequent leukopenia severity, on the other hand...
