Biologics / Biosimilars

Our integrated preclinical to early clinical offering covers recombinant proteins, monoclonal antibodies, oligonucleotides, vaccines, and other therapies. We have extensive experience in study design and PK/PD analysis of novel biologics and biosimilars in preclinical and clinical settings.

Our bioanalytical team analyzes biologics by LC-MS/MS and ligand binding, starting in animal matrices and moving to human. We measure anti-drug antibodies generated and determine if they are neutralizing using competitive binding or functional assays.

Our purpose-built clinics provide the close oversight required for treatment with novel biologics and biosimilars, and offer a high level of safety as well as comfort to participants for efficient recruitment and long-term retention.

We design, conduct, analyze, and report our studies in-house, drawing on our regulatory consultants, our experts in clinical conduct on biologics, and our biostatisticians, data managers, and medical writers with relevant experience in biologics and biosimilars.
