  • 253: How to Source, Manufacture, and Scale the Earliest Stem Cells for Allogeneic Cell Therapy Without Ethical Barriers with Yuta Lee - Part 1

    What if the key to scalable, off-the-shelf cell therapy was hiding in tissue that surgeons discard every day?

    Yuta Lee, Founder and CEO of Accelerated Bio, has spent two decades building a cell therapy platform on exactly that insight. Human trophoblast stem cells, sourced from ectopic pregnancy tissue that is otherwise discarded, sit at a unique biological intersection: earlier than MSCs, free from the ethical barriers of embryonic stem cells, expandable to 85 population doublings, and naturally equipped with HLA-G immune modulation that opens the door to allogeneic, off-the-shelf therapy at scale.

    Topics discussed

    • Common misconceptions and challenges in bioprocess development for biological therapeutics (02:45)
    • The origin story behind Yuta Lee's interest in stem cells, including his father’s surgical discovery (04:15)
    • A look at the intellectual property strategy that protected and enabled Yuta Lee's company to develop its platform (07:26)
    • A clear explanation of different stem cell types (embryonic, trophoblast, mesenchymal, adult, and induced pluripotent) and their sources (09:37)
    • Ethical and regulatory issues involved in sourcing stem cells, and how trophoblast cells offer a unique alternative (10:59)
    • Discussion of stem cell differentiation, population doubling, and scalability for manufacturing purposes (17:03)
    • Importance of immune privilege and HLA-G expression in pre-placental cells for off-the-shelf therapies (20:20)
    • Shifts in the industry from autologous to allogeneic therapies, and the role trophoblast cells may play in future treatments (22:00)

    In Part 2, Yuta Lee goes into the science of biological aging, the senescent cell secretome findings from the National Institute on Aging, and what a prevention-first therapeutic approach to healthspan extension could look like in practice.

    Smart insight:

    The scalability ceiling of MSCs is not just a manufacturing inconvenience, it is a strategic constraint. At 25 to 30 population doublings from birth-derived donors, every new donor batch requires revalidation as a distinct biological starting material. Trophoblast stem cells at 85 doublings from a single donor change that equation fundamentally, making true allogeneic scale not just biologically possible but manufacturable.

  • 252: How to Use Media Supplements to Tailor Biosimilar Glycan Quality to Your Reference Product in Two Rounds

    Are you still using one-factor-at-a-time experiments for biosimilar development, losing months, missing interactions, and risking costly dead-ends?

    In this episode, David Brühlmann, host of the Smart Biotech Scientist Podcast, reveals how traditional "one factor at a time" screening in biosimilar development can take over 12 months, while the parallel group design massively accelerates discovery by grouping up to five factors per experiment and applying a multivariate analysis pipeline.

    Topics discussed:

    • The limitations of traditional and large DoE designs and the advantages of parallel group design (00:08)
    • Best practices for grouping compounds by biological mechanism with four essential rules (00:53)
    • The importance of anchor compounds, separating strong modulators, and initial univariate screens for unknown compounds (01:43)
    • Guidance on managing practical issues, including evaporation, liquid handling, osmolality, and replicating production processes (06:42)
    • The use of multivariate analysis tools: Principal Component Analysis, Mahalanobis distance, and decision trees for candidate selection (10:14)
    • Key results and outcomes from applying the parallel group method, including faster and more cost-effective quality modulator identification (12:46)
    • Three improvements David would recommend today: prequalifying compounds, broader quality analytics, and hybrid modeling integration (13:49)
    • The shift in mindset from “time problem” to “information problem” in process development (16:50)
    • Extending the parallel group and multivariate approach to other areas like clone selection and scale-up decisions (17:52)

    Smart insight:

    Process development is fundamentally about generating actionable information, not just running more experiments. The parallel group, multivariate pipeline lets teams ask better questions, in parallel, with dramatically improved data yield. This mindset and methodology extend well beyond biosimilar media development into clone selection, feed design, and process characterization, wherever complexity would paralyze traditional approaches.

    If you want more detail, you can read the full article “Parallel experimental design and multivariate analysis provides efficient screening of cell culture media supplements to improve biosimilar product quality” published in Biotechnology and Bioengineering, which outlines the methods and findings behind this approach.

    If you’re interested in hybrid modeling, here’s what previous podcast guests have shared on the topic, offering perspectives from fundamentals to real-world applications.

  • 251: Why a Single Large DoE Fails Biosimilar Glycan Optimization — And the Parallel Screening Method That Actually Works

    Are you stuck screening endless compounds in biosimilar development and still not hitting your quality targets? Efficient compound screening is one of the toughest bottlenecks in biopharma, with outdated methods slowing progress and risking critical quality attributes in monoclonal antibody development.

    David Brühlmann breaks down a practical, parallel framework for rapid compound screening that addresses interaction effects, masking, and data quality. Methods proven in challenging biosimilar development programs.

    Topics discussed:

    • The historical bottleneck of one-at-a-time screening in drug discovery and the impact of high throughput methods (01:04)
    • Problems with both one-factor-at-a-time and large design of experiments approaches when handling many variables (02:10)
    • Description of the parallel group method: splitting 17 quality modulating compounds into five biologically relevant groups and running experiments in parallel (06:09)
    • How grouping compounds by biological mechanism improves interpretability and experimental design (06:43)
    • Strategies for minimizing dilution effects, toxicity risks, and masking in multi-factor screens (08:24)
    • The importance of multivariate analysis: using principal component analysis (PCA), Mahalanobis distance, and decision trees to interpret and select optimal experimental conditions (10:31)
    • Real-world outcomes: identifying optimal compound combinations in just two rounds of screening (15:20)
    • Reflections on the evolving role of hybrid modeling and machine learning in biosimilar process optimization (15:54)

    In Part 2, the focus shifts to a hands-on approach, covering how to design compound groups based on biology, set concentration ranges without compromising data quality, and execute a 96-well screen with the rigor the method demands. It also highlights three key aspects that would be approached differently if the study were conducted today.

    Strategic insight:

    Effective compound screening shifts from one-at-a-time testing to biology-driven parallel grouping combined with multivariate analytics, enabling faster identification of optimal combinations while preserving data quality and capturing interaction effects.

    If you want more detail, you can read the full article “Parallel experimental design and multivariate analysis provides efficient screening of cell culture media supplements to improve biosimilar product quality” published in Biotechnology and Bioengineering, which outlines the methods and findings behind this approach.

  • 250: How T Cell Activation Redefines TIL and CAR-T Manufacturing (Boosting Success Rates to 95%) with Chantale Bernatchez - Part 2

    When every batch belongs to a single patient, a single centralized facility cannot serve the world. In Part 2, Chantale Bernatchez moves from process development into the broader consequences of that reality: the manufacturing model built around clinical proximity, the global alliance bringing TIL production to regions with no current access, and the next-generation engineered approaches redefining what these therapies can do.

    Chantale Bernatchez is Head of Process Development at CTMC, a joint venture between Resilience and MD Anderson Cancer Center. If you missed Part 1, she explained how specific activation changes recovered a failing TIL process from 50% to 95% success in heavily pre-treated patients.

    Topics discussed:

    • How close collaboration with MD Anderson accelerates clinical development and regulatory readiness (03:08)
    • CTMC’s approach to process development and adapting to innovative technologies (05:15)
    • The value of partnership-based models versus traditional CDMO-driven approaches (06:24)
    • Global technology transfer: building alliances to expand access to cell therapies, with a case study in Brazil (07:35)
    • Key barriers and solutions for cell therapy manufacturing in new regions (09:41)
    • Practical advice for scientists starting in GMP manufacturing and process development (10:46)
    • Future directions in CAR T and TIL, including logic-gated CARs, engineered TILs, and in vivo therapies (12:24)
    • The importance of continued innovation and collaboration to expand global patient access (17:39)

    Smart insight:

    The choice of manufacturing partner in cell therapy is not a logistics decision. It is a process development decision. CTMC's collaboration-based model exists because many early-stage developers arrive without a process robust enough to hand over. For scientists in small or mid-sized companies, engaging that kind of partnership too late, or on purely transactional terms, is one of the most avoidable risks in early clinical development.

  • 249: How T Cell Activation Redefines TIL and CAR-T Manufacturing (Boosting Success Rates to 95%) with Chantale Bernatchez - Part 1

    The most underappreciated parameter in cell therapy process development is not your bioreactor, your media, or your activation protocol. It is the patient. Chantale Bernatchez has spent 20 years learning that lesson the hard way, watching the same manufacturing process succeed brilliantly with one donor and fail completely with the next. In this episode, she explains why starting material variability is the defining challenge of cell therapy manufacturing, and what it actually takes to build a process robust enough to survive it.

    Chantale Bernatchez is Head of Process Development at CTMC, a joint venture between Resilience and MD Anderson Cancer Center. She holds a PhD in immunology and has spent two decades advancing T cell therapy from early research programs at MD Anderson to GMP-compliant clinical manufacturing. She holds four patents in adoptive cell therapy.

    Key topics discussed:

    • Personal journey: from immunology PhD in Quebec to cell therapy leadership in Houston (04:25)
    • Evolution of TIL therapy at MD Anderson, including manufacturing innovations to overcome declining T cell yields (06:14)
    • The fundamental differences between traditional medicines and cell-based immunotherapies (10:01)
    • Unique manufacturing complexities for autologous therapies, including batch variability and process standardization (11:19)
    • Strategies to address decreased cell fitness in heavily pretreated patients, including changes in cell activation and culture conditions (13:57)
    • Key learnings from the CAR T and TIL manufacturing process: balancing process duration, cell fitness, and product yield (16:28)
    • Mechanistic differences between CAR T and TIL therapies and their implications for efficacy and resistance (17:58)
    • The limits and risks of automation in cell therapy manufacturing—balancing manual vs. automated processes (24:04)
    • Why moving between manufacturing platforms raises challenges in comparability and clinical outcomes (25:44)
    • The ongoing search for critical cell quality attributes that correlate with patient response (27:00)

    In part two, Chantale goes deeper into next-generation approaches, technology transfer, and what needs to change to broadly expand patient access.

    Smart insight: In cell therapy, manufacturing isn’t just a production step. It defines the therapy itself. Because each patient’s starting cells are unique, even subtle changes in the process can significantly alter clinical outcomes.

  • 248: Nitrosamine Risk Assessment and CRO Selection: The $6 Million Mistake CMC Teams Must Avoid with Ron Najafi - Part 2

    Getting an NDA signed shouldn't take weeks. If your CRO needs more than 48 hours to start the paperwork, your project timeline is already moving in the wrong direction.

    Ron Najafi knows what rigorous analytical work actually looks like under pressure. As founder and CEO of Emery Pharma, he led the investigation that identified NDMA as a degradation product of ranitidine — findings the FDA formally validated and that reshaped how the industry approaches nitrosamine risk assessment. In Part 2, he moves from that scientific foundation into the operational questions that determine whether a CRO partnership accelerates your program or quietly slows it down.

    If you haven't heard Part 1, it covers Ron's career arc and the technical details of nitrosamine contamination in pharmaceutical development. This episode stands on its own for anyone focused on CRO selection, bioanalytical strategy, and what three decades of building analytical companies actually teaches you.

    Topics discussed:

    • How to tell if a CRO’s workflow is robust—or just rigid (05:51)
    • The importance of method validation and product stability testing (07:27)
    • Managing expectations and trust-building in client relationships (08:29)
    • Entrepreneurial lessons: raising capital, team-building, and finding the right partners (10:00)
    • The hidden costs of public vs. private biotech ventures (12:31)
    • Reducing bioanalytical costs in biologics through mass spectrometry (13:23)
    • The future of analytical workflows and personalized medicine (14:48)

    Smart insight:

    In biotech, success isn’t just about the science—it’s about strategic discipline. Ron emphasizes a few hard-earned principles: raise more capital than you think you’ll need, don’t fixate on valuation, and invest in smart, creative talent. Just as important, real value is unlocked through strong partnerships and the ability to manage collaborations and acquisitions with intention.

  • 247: Nitrosamine Risk Assessment and CRO Selection: The $6 Million Mistake CMC Teams Must Avoid with Ron Najafi - Part 1

    When drug safety fails, patients and entire markets pay the price. Understanding your CMC isn't just compliance — it's the line between therapeutic promise and product recall.

    Ron Najafi has lived that reality firsthand. As founder of NovaBay Pharmaceuticals and Emery Pharma, he spent decades building companies at the intersection of analytical chemistry and drug development. His investigation into nitrosamine contamination in ranitidine — which led the FDA to formally validate Emery Pharma's findings — remains one of the most consequential episodes in recent pharmaceutical quality history.

    In Part 1, Ron traces the scientific and entrepreneurial path that led him there, and shares what CMC teams working in drug development need to understand about impurity risk before it becomes a regulatory crisis.

    Episode highlights:

    • Early academic experiences and inspirations that Ron Najafi to a science career (05:46)
    • Challenges and milestones in building companies like CP Lab Safety and NovaBay Pharmaceuticals (07:59)
    • The invention and impact of the ECO Funnel® on lab safety and environmental responsibility (12:01)
    • The formation of Emery Pharma following industry setbacks and lessons in adaptation (17:03)
    • The fundamentals of impurity risk analysis, especially nitrosamine contamination in pharmaceuticals (20:56)
    • The ranitidine (Zantac) NDMA discovery, its investigation, and consequences for drug regulation (23:33)
    • Common sources of nitrosamine and practical advice for bioprocess risk management (27:51)
    • Differences in impurity risk between small molecule and biologic drug processes (28:03)
    • The necessity and regulatory expectation of impurity and leachable/extractable analysis (30:07)

    Smart insight:

    One of Ron's clients conducted a superficial nitrosamine risk assessment, proceeded to manufacturing, and spent approximately $6 million producing three batches. At final FDA-required testing, NDMA came back at 11,000 nanograms per pill against an acceptable daily intake limit of 96 nanograms. The batches were unusable.

    A thorough risk assessment run earlier would have cost a fraction of that. If you are developing a drug with secondary or tertiary amines in your process and have not yet conducted a formal nitrosamine risk assessment, that is the one action to take after listening to this episode.
