    193: Viral Vector CDMO Mastery: Singapore's Answer to Cell and Gene Therapy Supply Shortages with Lucas Chan - Part 1

    Viral vectors are the backbone of cutting-edge cell and gene therapies, delivering life-altering treatments to patients with genetic diseases. But making these biological delivery vehicles is a high-wire act: unpredictable, complex, and fraught with hurdles that traditional biologics manufacturers have never faced. While the world races toward next-generation therapies, the challenge of producing viral vectors at clinical and commercial scale threatens to leave patients waiting on the sidelines. Our guest on the Smart Biotech Scientist Podcast is Lucas Chan, a molecular and cell biologist with over two decades of hands-on experience in cell and gene therapy development. From his formative research at Imperial College London, where he pioneered novel viral vector cell lines, to building the UK’s first GMP clinical viral vector core and later founding CellVec Pte Ltd Asia Pacific CDMO in Singapore, Lucas is the go-to architect for manufacturing viral vectors where infrastructure barely exists. Along the way, he’s faced and overcome challenges few others could imagine. Here are three reasons this episode is a must-listen: Viral Vectors Demystified: Lucas breaks down a common misconception: viral vectors aren’t malignant viruses, but genetically disarmed delivery vehicles that can’t revert or replicate, making them safe tools for gene therapy.Manufacturing Mayhem Made Manageable: Unlike monoclonal antibodies and other biologics, viral vectors (and other cell and gene therapies) are made in living cells, leading to a level of process unpredictability and complexity where “everything, everywhere, all at once” applies. Success hinges on scientific acumen and attention to even the smallest detail, from raw materials to equipment parameters, to ensure patient safety and product quality.Pioneering in Uncharted Territory: Moving from London to Singapore, Lucas faced not just technical but regulatory and logistical challenges to founding Asia-Pacific’s first CDMO dedicated to viral vectors. His advice: engage regulators early, leverage local biomanufacturing strengths, and build multidisciplinary teams to transfer and scale bioprocess know-how.Curious how viral vector manufacturing can be reimagined to unlock the full promise of cell and gene therapies? Listen to this episode and gain unique insights into the science, strategy, and sheer determination needed to bring advanced therapies out of the lab and into the clinic.

    192: Process Intensification Secrets: A Process Engineer's Decision Framework with Andreas Castan - Part 2

    Is continuous manufacturing delivering the transformative results everyone promised, or are you being sold an expensive solution to the wrong problem? While industry headlines tout revolutionary productivity gains, the economic reality behind continuous bioprocessing tells a more nuanced story that every process engineer needs to understand before making capital investment decisions. In this episode, host David Brühlmann continues his conversation with Andreas Castan, Strategic Technology and Business Development Leader at Cytiva, diving deep into the hard economics and operational realities of next-generation manufacturing strategies. Andreas brings over 25 years of bioprocess expertise from upstream innovation to cGMP manufacturing scale-up. Here are three critical takeaways from this conversation: Continuous vs Fed-Batch Economics Are Closer Than Expected: Andreas reveals real process economic modeling data showing that while continuous reduces capital costs through smaller bioreactors and facilities, higher media consumption (20-25% of COGS) and operational complexity often balance out the savings. The deciding factor isn't technology elegance but your specific production volume and pipeline needs.Regulatory Approval Isn't Easier Despite FDA Support: Even with regulatory enthusiasm for continuous processing, QA teams still demand the same fundamentals: traceability, batch definition, viral clearance validation, and process characterization. The technology choice should be driven by your business case, not regulatory preferences.Sustainability Benefits Are Modest: Contrary to industry hype, Andreas shares findings showing continuous manufacturing delivers only 20% carbon footprint reduction compared to optimized fed-batch. Real environmental gains come from HVAC efficiency and smaller cleanroom footprints, not inherent process advantages.Ready to cut through the marketing noise and make data-driven manufacturing decisions? This conversation delivers the unvarnished truth about when continuous processing creates real value and when intensified fed-batch might be your smartest investment.
