Pfizer’s Diverse Pipeline:

Delivering on Multiple Molecular Modalities

• Antibodies

– Standard Mab platform process using Protein A affinity capture (ProA), anion exchange chromatography

(AEX) polishing step, virus filtration (VRF) and ultrafiltration/diafiltration (UF/DF) for formulation

• Antibody Drug Conjugate (ADC)

– Typically standard mAb platform process but additional work may be required because of conjugation of

molecule

• Fc-Fusions

– Protein A Affinity capture step, VRF and UF/DF; may require non-platform chromatography steps (i.e.

cation exchange (CEX) , hydrophobic interaction (HIC) or ceramic hydroxyapatite (CHA) to address

increased aggregation, clipping or stability issues

• Therapeutic Proteins (e.g. Clotting Factors, recAP, Lagova, enzymes)

– Complicated processes employing multiple chromatography steps, precipitation, refolding, etc. and

analytics requiring more extensive development

• Vaccines (e.g. Trumenba, Prevnar, Staph A, C. diff, GBS, PNG)

– Extremely diverse modalities (microbial proteins, polysaccharides, VLPs)

– A number of molecules /processes make up one vaccine product (multivalent)

– Typically non-platform processes with unique challenges

• Gene Therapy (e.g. Duchennes Muscular Dystrophy, Factor IX, Factor VIII, Friedrich’s Ataxia)

– Early and late stage viral vector product pipeline with varying vector serotypes

– A platform process is being developed that can be used for future products

Challenges in Late Stage Development

• Unique for each program

• Maintain comparability as Process Evolves during Development

• Heightened Characterization

• Accelerated timelines (unmet clinical need)

• Portfolio Diversity (in-house & in-licensed assets, more than mAbs)

Tech Transfer to Clinical Manufacturing

• Started the tech transfer process in Feb for Sept runs

– Started early due to # of new raw materials and complexity of process

• Tech transfer modifications:

– Assess storage solutions for columns: Ethanol vs Benzyl alcohol

– Lowered challenge limits for both UFs : (Confirm in Pilot)

– Increased challenge to chromatography steps for flexibility in manufacturing

– New unit operation tested in pilot with direct feedback to manufacturing

– Added lower challenge to column loading range per manufacturing request

Support during Clinical Campaign

• Tech Transfer Team transitions to the clinical manufacturing.

• Person In Plant Program (PIP)

– PIP is fully trained in gowning and suite access to minimize PGS resource

drain

– Actively supports investigations and process troubleshooting

– Real Time Data analysis

• Remote access, sharepoint

• Tech Transfer Governance

Take Home Message

• Complex processes present a unique challenge.

• Start Early!

• (bias alert ☺ )Leverage your Pilot group.

• Encourage communication.

• Encourage transparency.
