From Bench to Bedside: Navigating the Regulatory Pathway for Cell and Gene Therapies By Donna Matuizek


Where Science Meets Regulation

When I first stepped into the world of cell therapy back in the early 2000s, I knew I was entering a space where science was rapidly evolving. I didn’t fully realize just how complex the regulatory journey would be for these types of therapies. Unlike traditional pharmaceuticals, cell and gene therapies don’t follow a one-size-fits-all pathway. They’re living products, often personalized, making their development incredibly promising and challenging.

At Dendreon, I was part of the team that helped bring Provenge, the first FDA-approved cell therapy for prostate cancer, to market. It was a milestone moment, but it didn’t happen overnight. It took a deep understanding of regulatory expectations, tight collaboration across departments, and a commitment to doing things the right way—even when that meant taking the longer, harder road.


It Starts at the Bench

Cell and gene therapies usually start in a lab, often as a concept that seems far removed from the patient. But from the very beginning, I’ve learned it’s essential to think with the end in mind. If you’re working in research or early development, keep asking: How will this scale? How will it be manufactured consistently? What will regulators expect in terms of safety and efficacy?

Too many teams wait until clinical phases or commercial planning to seriously consider a regulatory strategy. But in this space, every decision, down to the materials used and the assays developed, can have regulatory implications. The earlier you bring in Quality and Regulatory Affairs, the better your chances of avoiding major roadblocks later.


Bridging Science and Systems

One of the biggest challenges in navigating the regulatory pathway is translating groundbreaking science into something that fits into a structured, compliant system. Cell therapies don’t behave like small or large molecules. They require custom manufacturing processes, aseptic environments, and validation approaches that often don’t have clear guidance.

That’s where strong Quality Systems come in. At Just Biotherapeutics, when we were building a new clinical manufacturing site, we knew we needed both compliant and adaptable systems. We had to document every process, validate every environment, and still allow for innovation. It’s a tricky balance, but it’s possible with the right team and mindset.

Regulators aren’t just looking for data—they’re looking for confidence—confidence that the process is controlled, the risks are managed, and the product will be safe for patients every single time. That comes from having a clear story and systems supporting it.


Regulatory Relationships Matter

When it comes to cell and gene therapies, the FDA and other global regulators aren’t just gatekeepers—they’re partners. I’ve participated in numerous audits and inspections over the years, and what stands out most is that regulators truly care about getting effective therapies to patients. They ask tough questions, yes—but they also want to help you succeed.

Early and ongoing engagement with regulators is essential for a cell therapy product. Don’t wait for the pre-IND meeting to start the conversation. Use every opportunity—type B meetings, scientific advice consultations, even informal dialogue—to clarify expectations and gain alignment. That communication can make or break your development timeline.

At Magnolia Medical Technologies, for example, we worked closely with the FDA to achieve clearance for a Class II next-generation medical device aimed at reducing false-positive sepsis diagnoses. That collaboration was key to getting the product across the finish line and getting the product to as many patients as fast as possible.


Your Team is Your Greatest Asset

Navigating the regulatory path for these therapies is not a solo job. It takes a committed, knowledgeable, and flexible team. At Dendreon, I helped build the Quality Control operation from the ground up and was later responsible for overseeing clinical product manufacturing at two contract manufacturing sites. None of that would have been possible without a dedicated cross-functional team—from scientists to engineers to regulatory specialists.

Resilience and communication are non-negotiable. The pace is fast, the expectations are high, and the science constantly evolves. I’ve always believed in investing in people, building a culture of trust, and empowering team members to take ownership of their role in the bigger picture. That kind of culture shows during an FDA inspection—and even more so during those everyday moments when you’re solving real problems under pressure.


Patients Are Always the Priority

Getting caught up in the technical and regulatory details is easy, but we can never forget why we’re doing this work. These therapies are not just products—they’re potential lifelines. At Dendreon, I met patients whose lives were extended because of Provenge. That changes the way you see everything. Every SOP, every deviation investigation, every batch record becomes part of a patient’s story.

That sense of purpose has kept me in this field for decades. Whether I’m reviewing a validation protocol, leading an audit, or mentoring a new QA manager, I always come back to this question: Would I want my loved one receiving this therapy? I know we’re doing it right if the answer is yes.


Final Thoughts

Cell and gene therapies represent the cutting edge of what’s possible in medicine. But with that potential comes complexity. Navigating the regulatory pathway isn’t easy, but it is achievable with the proper foundation: early planning, strong systems, open communication, and a patient-first mindset.

From my first days in biotech in the 1980s to leading quality efforts in new manufacturing builds, I’ve seen firsthand how powerful these therapies can be—and how important it is to get them right. If you’re working in this space, stay curious, compliant, and focused on the people waiting for the hope these therapies bring.

The path from bench to bedside is winding, but it’s worth walking together.
