A Virtual Think Tank Executive SummaryTransition to Next Gen DownstreamProcessing to Capitalize on Growth Opportunitiesin High-Value Low-Volume BiologicsBy: Unmesh Lal, Program Manager,Transformational Health, Frost & SullivanFrost & Sullivan recently invited industry leaders in biopharmaceutical manufacturing to participatein a new and unique thought leadership forum, our Virtual Think Tank series. This forum broughttogether leading minds in manufacturing to discuss challenges, strategies, techniques,and barriers to new technology implementation in downstream processing.
A VIRTUAL THINK TANKEXECUTIVE SUMMARYChallenges in Downstream Bioprocessing NecessitateDisruptive Purification StrategiesUnmesh Lal opened the discussion by noting that the increasing demand forbiologics is driving the need for innovation in bioprocessing. The primary goalof downstream processing is the isolation and purification of the desiredprotein or nucleotide from the bacterial or animal cells that produce it in afermentation process.PANELISTSnnnnnnnnn2Christopher GillespieAssociate Director,Downstream ProcessDevelopmentImmunogen Inc.Paul JorjorianHead of BioProcess SciencesThermo FischerUmang TrivediAssociate Director,Global Tech OpsMerck & Co.Alexei VoloshinGlobal Application StrategyLeader3MDarshini ShahSenior Scientist DownstreamProcess DevelopmentPatheonAndrew TustainAssociate DirectorRegeneronHiren D. ArdesnaSenior Scientific Investigator,Downstream ProcessDevelopmentGlaxoSmithKline Inc.Jennifer PollardSenior Scientific InvestigatorMerck & Co.Russell OverbeckPrincipal ScientistBoehringer IngelheimThe fermentation processes that are used by biopharmaceuticalmanufacturers have shown to lead to increasing quantities of therapeuticproteins. Manufacturers are increasingly recognizing the present need forimprovement and have shifted their focus from improving the upstreamprocess to improving the downstream process. Umang Trivedi said,‘’The problem that we are facing right now is some of the inefficienciesin the process which are being brought to the forefront because of theincreased titres, increased cell densities that are coming out of theupstream processes.’’Challenges in downstream bioprocessing are driven by the pipeline growth ofvariable and complex emerging molecules such as bispecific antibodies,monoclonal antibodies (mAbs), antibodydrug conjugates (ADCs), and viralvectors for gene and cell therapies. From a CDMO (Contract Development& Manufacturing Organization) perspective, Paul Jorjorian, stated ‘’thisproblem of flexibility that you have some molecules that are demandingmetric tons, and then you have some that are, maybe it’s a couple batches ayear.’’ Echoing Paul, Russell Overbeck questions ‘’How do we device
A VIRTUAL THINK TANKEXECUTIVE SUMMARYstrategies for dealing with molecules where yes, we only need to make twoto three batches a year?’’ He continues to state that there is a need forstrategies and technology to be able to at least meet these new challenges inan innovative way – so we’re not treating different products the same way.Umang Trivedi contributes to the requirement for flexibility by commentingthat that while suppliers like GE, Sartorius, Pall, Millipore continue to makeprogress in downstream, we need to focus on verification strategies whichwill allow us to produce large amounts of drug substance using the smallestmanufacturing footprints.From a different perspective, Andrew Tustian notes that it is not that werequire completely disruptive purification strategies but a kind of anintensification and industrialization of the existing technologies. JenniferPollard supports the opinion stating, ‘’A lot of the challenges that we’ve beenfacing is just trying to do developments faster- this whole idea of acceleratingto the clinic. We do not necessarily need very disruptive verificationstrategies because there’s not always time to completely revamp something.’’KEY TAKEAWAYS: New developments in novel biologics and expansion in upstreamthroughput demands improvements in downstream capabilities. While new downstream technologies are emerging to increasethroughput times, reduce human resources and processdevelopment costs and increase yield, downstream processing isstill seen as the main technology bottleneck in the processingof biopharmaceuticals.“We need to focus onverification strategieswhich will allow us toproduce large amountsof drug substanceusing the smallestmanufacturingfootprints.”–– Umang Trivedi,Associate Director,Global Tech OpsMerck & Co.3
A VIRTUAL THINK TANKEXECUTIVE SUMMARYImplications of Small Batch Pseudo and FullyPersonalized Therapeutic DevelopmentRegenerative medicine and immunotherapy are at the forefront ofbiomedical research and are used to treat a variety of medical conditionssuch as cancer, neurodegenerative and other orphan diseases for whichmost of the currently available treatments are rather palliative.“Effectivecharacterization isthe key, effectivecharacterization of theproduct and then theprocess, how we candevelop the robustcontrol strategy of thesenew modalities.”–– Umang Trivedi,Associate Director,Global Tech OpsMerck & Co.4Investments across complex immunotherapies, alongside a strongpotential for personalized cell and gene therapies is shifting the marketparadigm towards low-volume high-value biologics manufacturing. Inparticular, with the recently launched therapies Kymriah and Yescarta, andan increasing number of products reaching late phase clinical trials, therewill be a growing need for increased large-scale manufacturing capacity.Manufacturing hurdles include the challenge that many of the T-cellprocesses involve very personalized patient specific production. Thiscommercialization of gene and cell therapies requires industrializedproduction approaches, which will drive technology innovation downstream.The key driver of these new modalities is shortening the productionprocess, thereby reducing the time required to get the product to thepatient. There is a demand for technologies that companies can adapt tointensify the production process without having to modify their existingmanufacturing facility. Umang Trivedi emphasized ‘’Effective characterizationis the key, effective characterization of the product and then the process,how we can develop the robust control strategy of these new modalities.’’Highlighting the requirement for smaller biotechs in regards to theircollaborations with CDMOs, Christopher Gillespie commented, ‘’ We don’thave our own independent manufacturing capabilities and we’re usingCMOs to partner and do these types of developments. And so havingdifferent types of technologies that are accessible across the, I guess CMOnetworks, would be something very advantageous. However, somebody likeus would probably be more risk averse of going towards some of thesenew technologies.’’
A VIRTUAL THINK TANKEXECUTIVE SUMMARYAdeno-associated virus (AAV) vectors have become one of the bestfitted platform technologies for in vivo gene therapy, mainly due to theirvaluable safety profile and their highly efficient transduction for varioustarget tissues. This requires all downstream purification steps to beupscaled while removing holdups present in traditional biomanufacturingmethods. Andrew Tustian explained, ‘’ The size may push you towardsmembranes and monoliths. And also it may push you to more kind ofcontained, fully contained system, so the kind of disposable systems thatyou can contain.’’Russell Overbeck elaborated ‘’But certainly when you look at cost ofgoods and things of that nature even from a development standpoint, inorder for these strategies to work, I think you're moving towards whatwould need to be high capacity, inexpensive, single use, disposablepurification technology that could potentially be portable.’’ Paul Jorjorianechoed the future of smart factories while providing a differentperspective stating ‘’That as you go to fully personalized, It’s almostequipment that is close to the patient, I always have envisioned, all of thestuff is going to move into the hospitals or to sort of care centers, akin tosort of dialysis centers if you think about it at some point, just because Ithink that’s the only place where you can even start to think about rollingout on a large scale and achieving the costs that are reasonable for thesetypes of therapies.’’ Jennifer Pollard added ‘’So a small profusion bioreactorattached in a closed system, the columns, and ending up sort of in afilled vial, all within like a bench top unit. That’s sort of what that’sgoing to look like. It’s not going to be a factory, it’s going to be somesort of clinical module.’’“So a small profusionbioreactor attached in aclosed system, thecolumns, and ending upsort of in a filled vial,all within like a benchtop unit. That’s sort ofwhat that’s going tolook like. It’s not goingto be a factory, it’sgoing to be some sort ofclinical module.”–– Jennifer Pollard,Senior ScientificInvestigatorMerck & Co.5
A VIRTUAL THINK TANKEXECUTIVE SUMMARY“Even if you workwith the monoclonalantibodies, or even ifyou work with the newmodalities, are youanswering the rightquestion, are you testingthe right attributes torelease this product intothe market to kind ofsatisfy the safety andefficacy requirement.”–– Alexei Voloshin,Global ApplicationStrategy Leader3MAndrew Tustian concluded, ‘’To achieve fully personalized medicine signifiesthat there is no more separation between your product and your productis your process because you're never going to fully validate your productssince you're always making a new product. What you can validate is thefact that your process will produce a product in a certain scaffold familywith certain quality and certain efficacy.’’KEY TAKEAWAYS: Cell and gene therapy is a highly invested area growing at a CAGRof 22.0% between 2017-22. With the advent of new modalities, there is an expected shift toflexible, small-volume manufacturing comprising of single-usesystems exploring continuous processing technologies inmodular facilities.Rethinking Collaborative PartnershipsAs biopharma manufacturing involves challenges from governmentalregulations to complex business models, the key pharma players in themarket are increasingly focusing on collaborating with players includingbiotech, CDMOs, CROs as well as regulators and technology vendors tomeet the evolving needs of the industry.6
A VIRTUAL THINK TANKEXECUTIVE SUMMARYBeing a highly regulated environment; timelines for the development andadoption of new technologies are lengthy. Concerns were raised, ‘’Even ifyou work with the monoclonal antibodies, or even if you work with thenew modalities, are you answering the right question, are you testing theright attributes to release this product into the market to kind of satisfythe safety and efficacy requirement.’’ Alexei added, ‘’And so the question isthat every single time you improve something, it will be either through acell line or through a certain purification technology, what are you givingup. And the things that you're giving up in terms of either performance,quality, or robustness, are they making your process riskier, both in termsof the risk to the patient, but also the risk of technical failure of theprocess itself as it migrates into commercial manufacturing. I think that’san area that should be scrutinized quite heavily as the improvements anddisruption in these processes accelerates.’’Connected factories and manufacturing error free are the tenets forflexible manufacturing solution providers. Umang Trivedi questioned, ‘’Can'twe reduce that human kind of operation to make our process much morerobust? Can't we have more automation in our process to gain thisproductivity and performance? We need to connect all these different ITsystems at some point to make it our digitalization much more efficient.So we can have the access of all the right data at the right time.’’ PaulJorjorian explained, ‘’ I think there’s also this question about how the data– these technology suppliers especially in the world of single usemanufacturing, but certainly applies to things like media, mediacomponents etc. flows in to what’s occurring within the shop floor.’’Jennifer Pollard emphasized ‘’We need to have collaborative relationshipsbetween the industry and technology suppliers.’’“We need to connectall these different ITsystems at some pointto make it ourdigitalization muchmore efficient.So we canhave the access of allthe right data at theright time.”–– Paul Jorjorian,Head of BioProcessSciences,Thermo FischerCorroborating the need for partnerships with technology suppliers, AlexeiVoloshin commented ‘’3M as a material science company, we can actuallygo look into our toolkit and to be able to understand what it is that wecan bring from this toolkit in order to make products which address someof these sort of changing paradigms that we’ve talked about today, forexample such as some of these newer modalities which not only requiresort of different chemistries but different physics as well because of theirbiophysical characteristics.’’Panelists agreed that a standard format for connectors, filters and columns,would make the implementation of a new technology easier. As an industry,pharma companies need to communicate with technology suppliers inregards to their challenges and feedback about their products. Anadditional benefit of these intra-industry collaborations would be to easethe filing burden, and other regulatory hurdles that companies face.7
A VIRTUAL THINK TANKEXECUTIVE SUMMARYKEY TAKEAWAYS: There is a need for digital continuity, connecting data tomanufacturing decisions across the value chain. There is a focus to improve productivity and have platformableprocesses for these new modalities, while meeting the high qualityand regulatory standards for the therapeutic. Collaboration and partnerships is the key to having the mostadvanced bioprocessing technologies.ConclusionA robust biologics pipeline coupled with a high growth rate is transformingthe biopharma manufacturing landscape. As the industry transitions from“small molecule” to “large molecule” manufacturing, advancements indownstream processing is necessary in removing purification bottlenecks,streamlining development, and reducing cost, complexity, and risksassociated with biopharmaceutical production. Innovation in functionalchemistries and materials science are creating opportunities fortechnology suppliers in integrating upstream and downstream unitoperations, buffer management and handling, highly selective affinity resins,membrane chromatography, depth filtration systems etc.Owing to this growing demand for biologics and biosimilars with complexmanufacturing requirements alongside a capital-intensive market, manypharmaceutical companies are seeing the profitability in collaborating withCDMOs and technology vendors for both clinical and commercial stagemanufacturing. Unified strategies will further ease the interaction with theregulatory bodies, ultimately resulting in high quality and timely launches,increased operational excellence and continuous improvement inmanufacturing.8
