279: Why Nanovesicles Outperform Exosomes: Scalable Drug Delivery Beyond Injectable Vaccines with Christopher Locher - Part 1
Aug 17, 202622 min
What if the best way to unlock durable, broad-spectrum immunity is to rethink the very vessels delivering our vaccines? While much of the industry focuses on refining existing delivery systems, Christopher Locher is charting a new course—one inspired by nature’s own couriers. Imagine a future where oral vaccines and modular, on-demand manufacturing aren’t just possibilities, but standard practice. Christopher Locher, CEO and Co-founder of Versatope Therapeutics, brings decades of experience in drug discovery from Vertex Pharmaceuticals, Opsona Therapeutics, and Maxigen. In this episode, he shares his journey from high school science classrooms to the helm of a company pioneering recombinant extracellular transport vesicles—nanovesicles that promise to transform vaccine delivery and immunomodulation. Topics discussed: How basic scientific curiosity and the inspiration from teachers sparked Christopher's career in biotechnology (03:39) The unmet needs in vaccine development for infectious and parasitic diseases, especially in regions below the equator (04:17) Engineering nanovesicles as immunomodulators and drug delivery vehicles, using microbial bioreactors for production (06:38) Co-producing proteins and vesicles in a single process, and the flexibility of the platform (08:28) Key benefits of Versatope's platform, such as cost efficiency, stability, and commercial scalability compared to mammalian exosomes (09:53) Prospects for multi-specific vaccines and the future direction for scalable bioprocessing (11:47) Adapting manufacturing processes and overcoming logistical challenges—from COVID-related shutdowns to supply chain bottlenecks (12:21) Strategies for navigating evolving regulatory requirements with agencies like the FDA, and experience with fast IND allowance (14:53) Analytical and characterization challenges of complex nanovesicle-based products versus simpler platforms like antibodies (17:30) The vision for decentralized or local vaccine manufacturing, especially in resource-limited settings (19:12) Smart insight: Christopher Locher highlighted that the FDA allowed their IND submission for a universal influenza vaccine in less than a month after review—and notably, with no hold clinical questions—when it was submitted just before the Christmas holidays and allowed on January 19th, 2025. This rapid regulatory turn-around was made possible by a strong regulatory team and collaborative CDMO efforts, showcasing how innovative platforms and well-prepared submissions can accelerate early-stage clinical development in biotech. If Christopher's vesicle platform has you thinking about building a novel modality on an unconventional host, these four episodes go deeper on alternative production systems, microbial scale-up, and the CMC and cost decisions that get a first-in-class biologic to patients.

278: Your Bioprocess Data Already Holds 35% More Yield: From End-to-End Models to Digital Twins with Ignasi Bofarull-Manzano - Part 2
Aug 12, 202619 min
How do you take a model that works in process development and get it accepted for use in GMP manufacturing? That question stalls most bioprocess modeling projects before they start. Ignasi Bofarull-Manzano, Senior Data Scientist and CMC Consultant at Körber Pharma, pushes back on the premise: the process you run today is already governed by a mathematical model, fitted once at small scale during process characterization and then left untouched for years, even as the process shifts. Part 1 separated digital models from digital shadows and digital twins, and made the case for starting with the decision rather than the data. Part 2 goes into the plant: what regulators actually require, what the numbers looked like on a real biologics process, and where a team should start on Monday morning. Topics covered: Core differences—and surprising similarities—between modeling in development versus manufacturing (02:35) Regulatory requirements: credibility assessments, model risk, and validation steps for digital twins (05:07) Real-world example: How deploying an end-to-end process model led to 35% yield increase for Takeda, and considerations for ROI in manufacturing (08:34) Advice for startup leaders on when to invest in modeling and how to scale efforts case-by-case (11:42) Steps for scientists new to modeling: identifying bottlenecks, starting simple, and proving value offline before scaling up (12:26) The importance of understanding basic statistics before relying on AI-generated models (15:22) A stepwise summary for deploying digital modeling effectively in biotech (16:01) Smart insight: The digital twin is the last step, not the first. Identify the bottleneck, build the simplest model that supports the decision, and concatenate it end to end so you can see how a parameter moves final drug substance quality rather than one unit operation's output. Prove the value offline. Only then connect interfaces, because that is where the cost and the validation burden live. Teams that lead with the twin arrive at the C-level with a proof of concept and no evidence. Teams that lead with the offline model arrive with a number. Before a digital twin can earn its keep, you need connected data, the right model, and a clear decision for it to support. These four episodes cover that ground — data silos, hybrid and mechanistic modeling, and twins built to survive regulatory scrutiny.

277: Your Bioprocess Data Already Holds 35% More Yield: From End-to-End Models to Digital Twins with Ignasi Bofarull-Manzano - Part 1
Aug 10, 202627 min
Most bioprocess teams believe a digital twin demands vast datasets and sophisticated models. Ignasi Bofarull-Manzano argues both assumptions are wrong, and that the data already sitting in your Excel files, historians and ELNs is probably enough to start. Ignasi Bofarull-Manzano, Senior Data Scientist and CMC Consultant at Körber Pharma, breaks down what a digital twin actually is, where modeling pays back fastest across the product lifecycle, and how to tell a real business case from an expensive proof of concept. In this episode: Misconceptions about data requirements for digital twins—why quality and context of data matter more than sheer quantity (02:40) Ignasi’s journey from curiosity in biology to a career in data science, modeling, and digital twins (04:31) Clear distinctions between digital models, digital shadows, and digital twins, explained with real-world analogies (06:42) How to approach digital development when faced with legacy data silos and scattered analytics (09:56) The importance of starting with a focused business need instead of chasing trends or buzzwords (12:28) Insights into where modeling truly delivers value in the product lifecycle—development versus manufacturing (13:11) Strategies for small companies to leverage digitalization and data from the ground up (15:56) An accessible overview of physics-informed AI, physical AI, and hybrid modeling—and their application in bioprocessing (18:15) The comparative advantages of physics-informed AI versus hybrid models in different bioprocessing contexts (24:45) Smart insight: Do not start with the model. Start with the bottleneck. Identify the business need first, then the decision the model must support, then the minimum data required for that context of use. Build the model offline, concatenate it end to end across unit operations rather than optimizing one in isolation, and prove the value before connecting a single interface. Teams that skip this sequence end up building models because models sound impressive, and those projects get expensive before they get useful. Before a digital twin can earn its keep, you need connected data, the right model, and a clear decision for it to support. These four episodes cover that ground — data silos, hybrid and mechanistic modeling, and twins built to survive regulatory scrutiny.

276: From Lab-Scale Molding to GMP: Manufacturing a Collagen Implant for the Clinic with Eva-Maria Balet - Part 2
Aug 5, 202618 min
How do you turn a lab-born regenerative medical device into a solution that surgeons actually want to use and investors want to back? The path from academic innovation to clinical adoption is full of practical hurdles and strategic pivots, where compelling science alone isn’t enough. David Brühlmann welcomes back Eva-Maria Balet, whose journey spans tissue engineering research at EPFL to leading Regenosca through first-in-human trials, fundraising, and an executive MBA completed while running the company. This conversation covers the practical realities behind that journey, from quality control to clinical setbacks to investor pitches. Topics discussed: Defining TissueSpan’s regulatory path and quality control as a medical device (02:49) The significance of first-in-human studies and what early clinical experience reveals (04:11) Selecting an initial clinical indication and opportunities for technology expansion (05:50) Realistic assessment of where soft tissue repair technologies apply—and where they do not (07:18) The stepwise progression from in vitro to animal models in product development (08:18) Navigating setbacks, including the impact of Covid-19 on clinical trials, and the value of adaptability (10:36) Bridging science and business in biotech fundraising and communication (12:15) Key takeaways from pursuing an executive MBA alongside building a biotech company (13:42) The importance of collaboration, mindset, and meaningful networks in driving biotech innovation (15:19) Smart insight: The transition from scientist to founder brought its own learning curve. Eva-Maria pursued an executive MBA while running Regenosca, and points to financial and business vocabulary as the skill she'd have built earlier if she could. For a technical founder or CMC lead, the lesson isn't to become a business generalist, it's that the moment you're translating a manufacturing process or clinical dataset into an investor pitch, fluency in the language of accounting, market strategy, and cost structure becomes as load-bearing as the science itself. This week's episode with Eva-Maria Balet steps out of bioprocessing into MedTech, following a collagen scaffold from EPFL lab bench to first-in-human implant. These back-catalog picks cover similar ground: what it takes to win investor buy-in beyond the science, the discipline of turning a lab process into GMP manufacturing, why regulatory classification shapes a product's whole trajectory, and what it really takes to commercialize a lab discovery. Episodes 259 - 260: Why Strong Science Isn't Enough to Get Funded: What Investors Actually Look For with Michael Rome Episodes 257 - 258: Why Regulatory Affairs Belongs in Drug Design: 30 Years of CMC Lessons from Discovery to GMP Manufacturing with Milan Tomic Episodes 105 - 106: From Proteins to Cell Therapy: Why ATMPs Aren't Just Complex Biologics with Oliver Kraemer Episodes 183 - 184: From Lab to Market: Secrets to Commercializing Cutting-Edge Biotech Innovations with Chervee Ho Connect with Eva-Maria Balet: LinkedIn: www.linkedin.com/in/eva-maria-balet-72561737 Regenosca website: www.regenosca.com Support the show
275: From Lab-Scale Molding to GMP: Manufacturing a Collagen Implant for the Clinic with Eva-Maria Balet - Part 1
Aug 3, 202617 min
Imagine a wound too large for the body to close on its own. That's the problem Eva-Maria Balet set out to solve, not with living cells, but with a structural bridge that lets the body's own healing mechanisms do the rest. In this episode, David Brühlmann welcomes Eva-Maria Balet, Co-Founder & CEO of Regenosca. Trained at EPFL, Eva-Maria brought her fascination with cellular "factories" from academia straight into entrepreneurship. Rather than chasing elegant science for its own sake, she built her company around a single principle: start with a real clinical need and build backward, collaborating with clinicians from day one so every experiment serves a patient. Highlights & Topics: Why starting with clinical needs—not just scientific excitement—creates meaningful real-world impact in life sciences (02:38) How Eva-Maria’s fascination with biotechnology guided her from cell factories to developing scaffolds for tissue repair (03:51) The unmet challenges in current soft tissue repair treatments and where new solutions are needed (05:51) What makes Regenosca’s fully-engineered collagen implant, TissueSpan, different from existing meshes and biological materials (07:09) The biological mechanisms behind tissue regeneration using a temporary collagen scaffold (08:28) Translating lab-scale research into a robust, scalable, and regulatory-compliant production process (10:34) The practical realities and hurdles of navigating the medical device vs. biologic regulatory pathways (11:59) Advice on building regulatory expertise into your founding team or leveraging consultants effectively (13:31) The importance of interdisciplinary teams and trust when forming biotech startups (14:36) Smart insight: Eva-Maria put it plainly: what works in the lab has to work reliably every single time you produce it for a patient. That shift, from proving a concept to controlling a process, from raw materials through in-process controls to final product testing, is the same discipline any CMC scientist recognizes: science alone doesn't get a product to patients. Reproducibility does. This week's episode with Eva-Maria Balet steps out of bioprocessing into MedTech, following a collagen scaffold from EPFL lab bench to first-in-human implant. These back-catalog picks cover similar ground: what it takes to win investor buy-in beyond the science, the discipline of turning a lab process into GMP manufacturing, why regulatory classification shapes a product's whole trajectory, and what it really takes to commercialize a lab discovery.
