    •   Selection of cell lines – product specific & IP sensitive   Many matured cell line platforms to choose from (e.g. mAbs: CHO, NSO, per.C6)   Cell line selection and construction in early basic research stage without considering manufacturing may result in challenges/ delays in commercialization   Select cell line critically with END in mind: titer, stability, product glycosylation & manufacturability   change of cell line post phase I clinical trials undesirable   process changes post phase II to be minimized Process is Product  Cell line dictates process
    • Selective to infection; reduces risk to adventitious agents   Swine cell lines: EB66 duck embryonic stem cell line by Vavilis shows promises A-Bio notes: process information is gathered from EPAR sources and published literature; CELVAPAN information is from Baxter
    • •  Product design & selection in early basic research stage without considering manufacturing may result in challenges/delays in commercialization •  Characterization of desired product driven by clinical needs impacts significantly downstream •  Product characterization requires advanced analytics •  Product complexity presents challenges in consistent supply to patients (eg. blood factors, live virus vaccines)   Multiple cell hosts developed at early stage for strategic decision including manufacturability Process is Product  Product quality challenges process (eg. glycosylation pattern)
    •   Glycan homogenity •  Large statistical population of variants •  Difficult to achieve due to macro and microhetergenity •  Achievable via process design and manufacturing consistency   Immunogenicity - injection site reactions/threat of anaphylaxis   Change in efficacy – ADCC response (Rituxin, tumor killing)   Product incomparability after scale up (Lumizyme, Genzyme) •  Myozyme (160L) = Lumizyme (2,000L) •  New BLA requested submission over carbohydrate structure changes   CMC comparability issues (Erbitux, Imclone) •  pre-clinical PK issues: sBLA for non-small lung cancer withdrawn •  Additional PK requested by FDA for Erbitux 1st line head & neck cancer Biopharm Bulletin.

    • Upstream Process Downstream Process  Disposable Technology: Eliminates CIP, SIP, utilities  Controlled Environment Modules: Gowning , operator mobility , protects product & people  Advantages: 60%++ reduction in capital investment, 40% less space needed, 85% reduction in water and waste, 32% reduction in COGS  Faster deployment: 12-18 months vs. 4+ years
    •   For biologics, Process is the Product – effective process development for manufacturing critical for product quality and consistency, hence commercialization.   Monoclonal anitbodies and vaccines present significant opportunities among future biologics being developed – advanced manufacturing platform available to improve productivity and reduce COGS.   Emerging market will enjoy significant growth in biopharmaceuticals driven by global changes   Drug development process paradigm shift towards earlier tech transfer around phase I for biologics – integrated cross functional CMC team, formed early to guide process development with END manufacturing ability in mind essential for successful commercialization.
