Introduction

Biologics have revolutionized the pharmaceutical industry, offering treatments for complex diseases that traditional small-molecule drugs could not effectively address. Biologics are derived from living organisms, unlike conventional drugs synthesized through chemical processes. They have shown great promise in treating conditions such as cancer, autoimmune diseases, and rare genetic disorders.
