Last month, Elodie, Magali, and I found ourselves in Lisbon—not for a spring getaway (though the weather was a delightful preview of the season) and certainly not for ultra-trail training (although the city’s hills did give our calves a solid workout!). Instead, we were there for EIP, an event…

What is a generic PK assay? A generic pharmacokinetic (PK) assay, also referred to as a universal PK assay for New Biologic Entities (NBE), is used to measure circulating human biotherapeutics—primarily antibody-based—post-administration across various non-human matrices. These assays are particularly beneficial when drug-specific reagents, such as anti-idiotype antibodies, are…

The Role of Pharmacokinetics (PK) in Drug R&D Pharmacokinetics (PK) is defined as the study of the fate of a new therapeutic entity (NTE) after it is administered into the body of animals or humans. It involves understanding how the drug is absorbed, distributed, metabolized, and eliminated (ADME). Essentially, PK…

Charcot, Gehrig, Hawking: A Journey Through ALS When you hear the names Charcot, Gehrig, and Hawking, what comes to mind? These names are all linked by a shared thread: Amyotrophic Lateral Sclerosis, or ALS. ALS, also known as Charcot disease, is named after Jean-Martin Charcot, a neurologist from the Pitié-Salpêtrière…

In the scientific field, the often neglected fifth sense, the sense of smell, contributes to broadening our understanding of various phenomena, particularly in the field of biomarkers.Here, we will guide you along our lines of thought on the importance of our olfactory sense, and how it contributes to scientific exploration…

Immunoassays are bioanalytical methods that generally use antibodies to detect and quantify specific analytes, often proteins, in biological samples. The process involves the capture of a target protein by an immobilized antibody, followed by its detection with another antibody conjugated either to enzymes, such as phosphatase alkaline or horseradish peroxidase…

Immunogenicity refers to the ability of a substance, such as an antigen or a vaccine, to provoke an immune response in an organism. The recognition of the substance as foreign triggers an immune response, which involves the production of antibodies and the activation of immune cells to fight against or…

ELISpot (Enzyme-linked immunosorbent spot) is an immunoassay-based technique used to quantify cells that are capable of secreting proteins, including cytokines, cytotoxic molecules, and antibodies, when stimulated with the appropriate antigen. Initially designed to monitor the frequency of circulating antigen-specific memory B-cells, it is now commonly used to determine the frequency…

Ligand binding assays (LBAs) have been our core activity for decades. LBAs are commonly used to measure interactions between two proteins, a ligand and its receptor, a monoclonal antibody (mAb) and its target, or biologics and Anti-Drug Antibodies (ADA). Throughout the development of New…

A biomarker is a defined characteristic that is measured as an indicator of normal biological processes, pathogenic processes, or biological responses to an exposure or intervention, including therapeutic interventions(1). With the development of innovative and personalized therapies, biomarker tracking is increasingly important to support the clinical development…
