Introduction

The advent of biologic therapies has marked a significant milestone in the treatment of various complex and chronic diseases, including cancer, autoimmune disorders, and infectious diseases. These biologics, which include monoclonal antibodies, recombinant proteins, and gene therapies, offer targeted and personalized treatment options that can dramatically improve patient outcomes. However, the effectiveness of these therapies is often influenced by individual patient characteristics, dosing regimens, and potential immune responses, making therapeutic drug monitoring (TDM) a critical component of optimizing treatment [1].

Therapeutic drug monitoring for biologics involves measuring drug levels, assessing the presence of anti-drug antibodies, and evaluating pharmacokinetic and pharmacodynamic parameters to ensure optimal therapeutic efficacy and minimize adverse effects. Despite the advancements in biologic therapies, there remains a significant gap between the development of these drugs in research settings and their practical application in clinical practice. Bridging this gap requires sophisticated monitoring techniques and a deeper understanding of how various factors influence drug behavior in the body [2].

Recent advancements in TDM for biologics have the potential to enhance treatment precision and patient outcomes. Innovations such as more sensitive and specific assays, improved pharmacokinetic modeling, and personalized dosing strategies are paving the way for more effective and individualized patient care. These developments promise to refine the management of biologic therapies by providing clinicians with better tools to tailor treatments to individual needs and optimize therapeutic responses [3].

This review aims to explore the latest advances in therapeutic drug monitoring for biologics, focusing on emerging technologies, methodologies, and clinical applications. By examining recent progress and identifying key challenges, we seek to provide insights into how these advancements can bridge the gap between bench research and bedside practice, ultimately improving the delivery of biologic therapies and patient outcomes.
