Bevacizumab-based chemotherapy adaptive to pharmacokinetic of bevacizumab in first-line treatment of patients with unresectable metastatic colorectal cancer: A double-blind, multicenter, randomized phase III trial study (PHARBEVACOL trial).

Bevacizumab shows inter-individual pharmacokinetic variability, with an exposure-response relationship in metastatic colorectal cancer (mCRC) patients. This study explores whether a double dose of bevacizumab, compared to a standard dose, increases efficacy in mCRC patients treated with bevacizumab-based chemotherapy as first-line therapy and who have a low initial trough concentration of bevacizumab. PHARBEVACOL is a multicenter, randomized, double-blind, two-parallel group trial.

A Fab of trastuzumab to treat HER2 overexpressing breast cancer brain metastases.

Despite major therapeutic advances for two decades, including the most recently approved anti-HER2 drugs, brain metastatic localizations remain the major cause of death for women with metastatic HER2 breast cancer. The main reason is the limited drug passage of the blood-brain barrier after intravenous injection and the significant efflux of drugs, including monoclocal antibodies, after administration into the cerebrospinal fluid. We hypothesized that this efflux was linked to the presence of a FcRn receptor in the blood-brain barrier.

Confounding mitigation for the exposure-response relationship of bevacizumab in colorectal cancer patients.

Aims: The exposure-response relationship of bevacizumab may be confounded by various factors, including baseline characteristics, time-dependent target engagement and recursive relationships between exposure and response, requiring effective mitigation. This study aimed to investigate the exposure-response relationships of bevacizumab in metastatic colorectal cancer (mCRC) patients while mitigating potential biases.

Methods: Bevacizumab pharmacokinetics was described using target-mediated drug disposition modelling.

Relationship Between Cetuximab Target-Mediated Pharmacokinetics and Progression-Free Survival in Metastatic Colorectal Cancer Patients.

Background And Objective: Cetuximab, an anti-epidermal growth factor receptor (EGFR) monoclonal immunoglobulin (Ig)G1 antibody, has been approved for the treatment of metastatic colorectal cancer (mCRC). The influence of target-antigen on cetuximab pharmacokinetics has never been investigated using target-mediated drug disposition (TMDD) modelling. This study aimed to investigate the relationship between cetuximab concentrations, target kinetics and progression-free survival (PFS).

Panitumumab and cetuximab affect differently miRNA expression in colorectal cancer cells.

Resistance to anti-EGFR monoclonal antibodies in metastatic colorectal cancer (CRC) is frequent and prognostic biomarkers are lacking. MicroRNAs (miR) are good candidates in this context. We aimed to characterize cetuximab and panitumumab exposure influence on miR expression in colorectal cancer cells to identify those regulating the EGFR pathway and implicated in resistance to treatment.

A robust enzyme-linked immunosorbent assay to measure serum ramucirumab concentrations.

Ramucirumab, an anti-VEGFR2 monoclonal antibody, has been approved for the treatment of metastatic gastric and colorectal cancer. An assay measuring ramucirumab serum concentrations was needed to investigate its pharmacokinetics and concentration-response relationship. An ELISA was developed and validated according to the international guidelines for ligand-binding assays.

Therapeutic Antibodies for the Treatment of Respiratory Tract Infections-Current Overview and Perspectives.

Respiratorytract infections (RTIs) are frequent and life-threatening diseases, accounting for several millions of deaths worldwide. RTIs implicate microorganisms, including viruses (influenza virus, coronavirus, respiratory syncytial virus (RSV)), bacteria (, , and ) and fungi ( spp., spp.
