Abstract
Biologic medicines (or biologics) have revolutionized the treatment of cancer, autoimmune disorders, and genetic conditions. Their therapeutic success stems from complex structural properties that confer high target specificity and biological compatibility. However, their high cost and complex manufacturing limit patient access, with annual treatment expenses often reaching tens of thousands of dollars per patient. Biosimilars, developed to match reference biologics in quality, safety, and efficacy, provide a pathway to curb escalating costs. Having generated more than 36 billion USD in healthcare savings over the past decade, their wider adoption remains challenged by stringent regulatory pathways and the market exclusivity of reference products. These limitations have spurred the development of biobetters, which are engineered biologics with enhanced stability, potency, half-life, or reduced immunogenicity that maximize patient benefit. This review explores the distinctions, development strategies, and regulatory challenges of biologics, biosimilars, and biobetters. Biosimilarity establishment and biobetter design strategies are examined with emphasis on enzyme-based examples such as L-asparaginase and glucarpidase. Advanced delivery technologies have also been demonstrated to improve drug stability, bioavailability, and patient adherence. Finally, emerging innovations and future directions underscore the transformative potential of these biopharmaceuticals in addressing unmet medical needs and expanding global access.
