People are part of an astonishing variety of life.

Chronic Kidney Disease
People with kidney disease do not make enough of the EPO protein, produced by the kidneys to stimulate production of red blood cells.
Erythropoietin (EPO) Protein
When complex processes are all working precisely, we are healthy…
But for many people, something goes wrong. Disease is the result.

Biologics Differ From Traditional Drugs in Both Complexity and Sensitivity
ManufacturingUnique bank of living cells;Unlikely to achieve identical copy
Predictable chemical & reagent reaction;Identical copy can be made
CharacterizationMany products well-characterized;Correlation of structure-function elusive
Easy to fully characterize
StabilitySensitive to storage and handling conditions
More stable
Immunogenicity Higher potential Lower potential
Structure Complex Simple
Stability Complex Degradation Stable
Variability Heterogeneous ‘product’ Single defined structure
Biologics(Protein-based medicines)
Pharmaceuticals(Chemically-based drugs)

Typical Protein Production ProcessTypical Protein Production ProcessTypical Protein Production ProcessTypical Protein Production Process
Fermentation units. Host cells thrive in these vats (also called bioreactors) filled with a life-sustaining bath of nutrients.
Fermentation is the science of growing host cells in large quantities, so that the gene inside them produces the protein that we want in large quantities.
Typical Protein Production Process
Put gene intoDNA vector
Identify and isolate gene that will produce a medically useful protein
Transfer into Host Cell ExpressionScreening/Selection
DNA vectors are used to move genes into new organisms. They are generally plasmids (pieces of bacterial DNA that can live and replicate outside the chromosome).
Chinese hamster ovary (CHO) cells were introduced in the early 1960s as an ideal cell line for genetic studies.
Genes won’t produce proteins outside of a living cell, so we have to insert our gene into a living cell (a “host cell”).
Biotech Medicine: The final protein must have precisely the right amino acid sequence, folded into precisely the right three-dimensional shape. Downstream
Extraction/Purification/Dilution
We must validate that downstream processing continues to remove viruses, DNA and toxins from the protein product stream.
Validation testing may be defined as “the act of proving that any procedure, process, equipment, material, activity or system leads to the expected results.”

Biocomparables:Similar, not Identical to Original Products
Different cell lines
Different manufacturing processes
....but not identicalBiocomparables are similar...
Impact of small differences in either biological or manufacturing process could lead to different clinical efficacy and safety for patients
No therapeutic substitution
Immunogenicity differences

We must always keep patients in mind.
