Understanding The Difference Between Small-Molecule Drugs And Biotherapeutics

Join our experts, and by attending this forum, you will:

• Enhance your comprehension of the fundamental differences between small-molecule drugs and biologics, including monoclonal antibodies (mAbs) and various novel drug modalities.
• Recognise the testing requirements, critical quality attributes (specifications), and regulatory expectations and challenges faced in the pharmaceutical and biopharmaceutical sectors.
• Learn how to apply and adapt any developmental experience with small-molecule drugs to biologics.
• Understand what does and does not translate from small-molecule drug development to biologics, and where thoughtful adaptations are critical.

Event Overview

Presentation #1: An Overview of Key Differences of Small-Molecule Drugs and Biotherapeutics: Perspectives and Quality Attributes

Understanding how foundational quality approaches for small-molecule drugs translate—or fail to translate—to biotherapeutics is essential for modern drug development. This session provides a comparative overview, starting with small molecules and their chemical properties, manufacturing, and testing practices. It then examines biotherapeutics, highlighting their biological complexity and bioprocessing techniques.

Key topics include differences and similarities in physicochemical and pharmacological properties, formulation strategies, analytical testing requirements, and critical quality attributes (CQAs). The discussion also explores how quality models developed for small molecules may inform biologics development and the impact on drug purity. Regulatory frameworks and market access considerations—generics versus biosimilars—will be addressed, with a case study illustrating practical implications.

Presentation #2: A Journey of a developmental scientist from Biologics to Synthetics, and then Novel Drug Modalities

This session follows the evolution of a developmental scientist navigating between monoclonal antibodies (mAbs), small-molecule drugs, and emerging drug modalities. Special attention will be given to manufacturing and purification strategies, comparing chemical synthesis with fermentation and bioprocessing methods.
Discussions will explore how quality control principles shift across modalities, with a focus on process design, PAT tools, regulatory expectations, and technical innovations. Several case studies are demonstrating how technical innovation can impact the way we perform QC testing strategies and how we understand manufacturing processes.
