Definition of Biotechnology
• Bio – deals with living organisms
• Technology – involves the practical application of knowledge
Therefore, Biotechnology is the practical application of knowledge related to living
organisms
Biotech vs Biologicals
• Biologicals are products which quality, purity, specificity, and potency cannot be expressed completely by chemical and physical terms (UK approach)
• Origin, manufacture and structure are not mentioned, therefore includes– immunological products (vaccines, toxins, serum,
and allergens -89/342/EC)– products from human blood or plasma -
89/381/EC
Wide Range of Products
• New molecular entities:– Recombinant DNA products
• CHO products• Proteins from milk of transgenic animals
– Gene therapy products
– Cell therapy products
– Monoclonal antibodies
Evolution of Biotechnology
10,000 BC: Alcohol fermentation, bread, cheese & yogurt
5,000 BC: Beer is brewed in Egypt
Evolution of Biotechnology (Overview)
• Whole Organism (macroscopic level)• Cells and other Microorganisms• Subcellular
– Components of the cell (organelles)– What did these components do?
• Nucleus and its Genetic Material– How did this material control the cell?– How was this information passed on
as the cell divided?
1953
Watson & Crick resolve the double helix structure of DNA
Evolution of Biotechnology 1800 - today
Key Developments in Biotechnology
• Cell Culture (bacteria, yeast, CHO)
• Monoclonal Antibodies
• Molecular Biology– Genetic Engineering– Recombinant DNA Technology– Transgenic Animals– Cloning
• Stem Cells (Great Potential)

Implication of the manufacturing process on a r-DNA biotech product
• The process defines the product
and
• The process determines the quality and reproducibility
Note: case by case assessments
Regulatory Requirements
• Quality, Safety and Efficacy– Less guidance available compared versus NCEs
• Quality specifics:– Characterization– Viral safety– Cell banking
• Preclinical specifics:– ICH S6 versus ICH M3– Immunogenicity
• Clinical specifics:– dependent on product– Immunogenicity
