Three Questions with CEO Andrew Knudten

  1. What excites you about the gene and cell therapy industry right now?
    We are fortunate to be part of an extremely exciting time for gene and cell therapy product development. Advances in technology, the sheer number of programs in development as well as recent product approvals all point toward continued progression. One thing I’m particularly excited about is that regulators are supportive of the rapid growth we are seeing in the gene and cell therapy space. The U.S. Food and Drug Administration’s Center for Biologics Evaluation and Research has made it clear that they aim to address key challenges to the development of gene and cell therapies, especially for rare disorders, and they want to work with sponsors to advance medicines for patients. This is great news, but I think we as an industry play a key role in that effort. Frankly, we need to make the jobs of regulators easier, especially in the area of manufacturing and analytical testing.
  2. That’s not something you hear very often. What exactly do you mean when you say the industry should make the jobs of regulators easier?
    Industry and regulators are sometimes framed in opposition, but we are on the same side. We all want to see safe and effective treatments reach the patients and families who need them. As an industry, our approach to manufacturing, analytical method development, and QC testing has not fully enabled the development of therapeutics regulators want to see and patients are desperately seeking. We need to evolve as an industry and begin delivering the quality of product that patients deserve and regulators expect. In the past, it may have been that technology was still catching up, but now we have access to the technology we need. It’s not just technology, though. We need to have people with the breadth of experience and expertise needed to harness the technology. Simply put, more time and energy needs to be invested in CMC product development so that CMC is not a major topic during regulatory interactions. How great would it be for regulatory interactions to focus exclusively on preclinical data review and clinical trial design instead of CMC-related topics? Choosing a CDMO with experience can help achieve this goal for complex gene and cell therapy medicines.
  3. What are some of the common CMC challenges that come up in regulatory discussions? Are they solvable?
    One issue that has been widely scrutinized is product purity or rather a product’s impurity profile. Immature manufacturing processes may produce drug product that has unacceptable levels of process and product-related impurities. Regulators assess a product’s impurity profile as part of their quality and safety assessments. Another challenge biopharmaceutical companies may come up against is bridging between an early manufacturing process and a commercially-viable manufacturing process. Ideally, sponsors should develop a commercially-viable manufacturing process at the onset of a program. Financial and strategic considerations, though, do not always allow for this. Some sponsors may also find themselves in a situation where they’ve inherited a product that has promising clinical data but was supplied with an immature manufacturing process. This might seem provocative, but sponsors should not be afraid of comparability or bridging studies! Recently, regulators have reinforced that they are very open to modifying a gene or cell therapy manufacturing process if the sponsor can confirm the dose, demonstrate process control and its impact on critical quality attributes, and prove analytically the product produced via a new manufacturing process is more pure than the previous iteration. An experienced CDMO like Advanced Medicine Partners can help a sponsor develop a prospective comparability plan that will be looked on favorably by the regulators. We do this through employing advanced analytics to clearly quantify attributes of product made through each manufacturing process. This allows us to ensure product quality is better through the new manufacturing process and that we are delivering an accurate and precise dose. Sponsors should not be satisfied with a sub-optimal manufacturing process. Patients deserve better.

How We Stand Apart to Deliver the Science, Partnership and Technical Solutions You Need

At Advanced Medicine Partners, we have a very clear vision for our company – to be THE leader in process development, manufacturing, analytical development and testing for advanced therapy products. Our vision stems from our deep desire to improve the lives of patients and their families, and from our unrelenting drive to push the boundaries of science to create the purest and most potent medicines possible. To become THE leader, though, we have to clearly differentiate ourselves from traditional contract development manufacturing organizations (CDMOs). Having spent many years as clients ourselves, we identified three key areas that would set Advanced Medicine Partners apart from the rest: experience, past successes and a proven track record; depth and breadth of capabilities; and a true partnership mindset focused on accelerating programs, not slowing things down. We have been on the other side of the table, so we know how important these differences are.

We are fortunate at Advanced Medicine Partners to have one of the most experienced genetic medicines teams – at all levels, from bench to boardroom – in the industry. We boast 583 combined years of biopharma experience and 217 combined years of gene therapy CMC experience. While those numbers are impressive, it’s more important what our team accomplished in those years. For example, we have led CMC efforts for three globally approved gene therapies. Part of that work involved taking an academic manufacturing process and scaling it up for clinical and commercial needs, while working with regulators to ensure a robust CMC package and prove comparability between the academic and commercial process. We have also developed a best-in-class proprietary AAV manufacturing process that prioritizes patient safety by minimizing process and product related impurities while still maintaining industry-leading batch yields.

We’ve taken our experience and previous successes and built on them to be able to offer expansive development capabilities to partnering companies.

  • Process Sciences: We conduct both small- and large-scale development work and have completed experiments ranging in scale from small well plates to 2L and 5L benchtop bioreactors, to AMBR modular bioreactor systems, to 200L and 500L commercial-scale bioreactors. With a wide array of equipment in varying scales, manufacturers and in-process testing capabilities, we can execute early-stage bench scale development work through commercial-scale IND-enabling material generation.
  • Analytical Development: Advanced Medicine Partners has state-of-the-art analytical laboratories and equipment, which are designed to provide accurate and reliable results that meet cGMP standards. Our facilities are equipped with advanced instrumentation and technology. Our platform methods are already qualified and readily available. Many of our assays are validated and available for GMP product testing and release.
  • Quality and Regulatory Consultation: We offer a full suite of quality and regulatory consultation services. Our team has a deep understanding of successful CMC regulatory packages. We offer our partnering companies CMC strategy development, IND/IMPD CMC documentation preparation and agency support.
  • GMP Manufacturing: Advanced Medicine Partners uses a commercially viable GMP-ready process to generate product for preclinical studies, product characterization, stability, and a host of other uses including material compatibility and other tests required by regulators. We are in the process of building out a 174,000-square-foot cGMP manufacturing facility with the flexibility for clinical and commercial production across modalities. We anticipate it to be fully operational supporting clinical GMP in early 2025.

When it comes to adeno-associated virus (AAV) work, we have developed a robust and reproducible manufacturing process that is commercially viable and highly productive, including best-in-class analytics and characterization. Our innovative AAV process is one of the most productive in the industry (see figure 1).

Figure 1

There’s no doubt that experience and past successes as well as current capabilities are critical, but we think our MOST important differentiator is our partnership mindset. Traditionally, CDMO operations work independent of their clients – we want to be your partner in the truest sense of the word. We want you to think of us as your extended workbench because we know real-time data helps you drive decisions and accelerate your programs. Our partnership philosophy is fully collaborative and amplifies the capabilities of our partners. By leveraging our collective knowledge and experience (your experience and Advanced Medicine Partners’ experience), we will build a long-lasting partnership that allow for delivering fast and effective solutions for patients.

We are so proud to have launched Advanced Medicine partners to set new standard in developing and manufacturing innovative medicines. From the start, we have had our partnered companies in mind and have built our entire operation to stand apart by delivering the science, partnership and technical solutions you need.
