Managing Quality and Regulatory Risks in Pharmaceutical Technology Transfer

Technology transfer moves more than manufacturing instructions. It moves process knowledge, supplier dependencies, labeling requirements, packaging specifications, and the evidence needed to demonstrate control. For medical device manufacturers, including those supporting drug-device combination products, these interfaces can become recurring sources of compliance gaps during site transitions, acquisitions, and remediation. The central problem is often not a missing procedure. It is a quality system that allows connected activities to change independently. A label revision may be approved while packaging artwork, supplier instructions, or production-system data still reflect an obsolete version. Staying inspection-ready requires manufacturers to manage these dependencies as one controlled system. Why Compliance Gaps Keep Recurring Findings are treated as documentation defects Revising a procedure can resolve an immediate discrepancy without changing the behavior that caused it. If unclear decision rights, weak escalation, or ineffective training remain, the same failure may surface elsewhere. Corrective and preventive action should distinguish the observed finding from its underlying cause and establish how effectiveness will be demonstrated. Ownership is divided across connected functions Quality, Regulatory Affairs, labeling, packaging engineering, operations, suppliers, and digital-system owners often maintain separate workflows. Each team may complete its assigned task while an interface remains uncontrolled. For example, changing an instruction for use can affect packaging configuration, translations, technical documentation, inventory disposition, and release controls. Transitions expose unresolved weaknesses Acquisitions and site transfers can introduce conflicting procedures, incomplete knowledge transfer, or different assumptions about validated processes. Regulatory changes add further demands. When these events coincide with CAPA or change-control backlogs, teams may prioritize administrative closure over risk reduction. Without a coordinated impact assessment, local fixes can create new gaps downstream. Establish the Regulatory Baseline Inspection readiness starts with knowing which requirements apply to the product, activity, and market. Pharmaceutical, device, and combination-product obligations are not interchangeable; transfer planning should identify the applicable requirements rather than assume one quality framework covers every operation. According to FDA’s Quality Management System Regulation overview and FAQs, the QMSR became effective on February 2, 2026, incorporates ISO 13485:2016 by reference, and introduced the updated device inspection process under Compliance Program 7382.850. ISO 13485 certification does not exempt a manufacturer from FDA inspection or guarantee compliance with FDA requirements. For devices marketed in the European Union, Regulation (EU) 2017/745, Annex I, Section 23, provides the primary requirements for information supplied with devices, including labels and instructions for use. Teams should assess the applicable provisions alongside relevant language, product-specific, and market requirements. A labeling review should therefore evaluate required content and consistency with the device’s intended purpose and supporting documentation—not merely artwork accuracy. How to Identify the Real Gaps Begin with a cross-functional assessment that follows actual product and information flows. Select representative transfers, label changes, supplier changes, and CAPAs, then trace each from initiation through implementation and effectiveness review. Map dependencies: Identify affected specifications, suppliers, packaging components, systems, validation activities, and training. Compare records with practice: Check whether approved procedures match what operators and reviewers actually do. Test traceability: Follow a requirement through technical documentation, labeling, production instructions, and release evidence. Examine recurrence: Look for repeated deviations, reopened actions, overdue changes, and findings shared across sites. Assess capacity: Determine whether qualified owners have enough time and authority to complete corrective work. Prioritize gaps by potential patient or user harm, regulatory impact, likelihood of recurrence, and detectability. Document the rationale; an old overdue item is not automatically more important than a newly identified high-risk weakness. Align Quality, Labeling, Packaging, and Change Control Create a coordinated remediation plan with one accountable owner for each action, named contributors, acceptance criteria, and required evidence. Separate immediate containment from systemic correction. Containment might prevent obsolete labels from being issued; correction might redesign approval and implementation controls so obsolete versions cannot return. Use change control as the integration point. Before approval, evaluate effects on regulatory submissions or notifications, technical documentation, supplier controls, packaging performance, validation, electronic master data, inventory, and training. Record both identified impacts and justified decisions that particular activities are unaffected. During technology transfer, define readiness gates before production or release responsibilities move. These should address the transfer of process knowledge, acceptance criteria, receiving-site capability, required qualification or validation, approved documents, and personnel competence. The appropriate evidence depends on the product and process; a generic checklist cannot replace a documented assessment. Finally, verify implementation where the work happens. Confirm that current instructions are available, suppliers received approved requirements, systems contain correct versions, and affected personnel can perform their tasks. A signed approval is not evidence that every downstream change took effect. Mistakes That Undermine Inspection Readiness Closing CAPAs on task completion alone: Effectiveness checks should test whether the underlying failure has been controlled. Updating labels in isolation: Assess packaging, supplier, system, documentation, and inventory consequences. Counting closures instead of evidence: Dashboards need defensible records behind their status indicators. ...

Dyadic International, Inc. a leading biotechnology innovator focused on accelerating the development and lowering the manufacturing costs of vaccines and biopharmaceuticals, recently announced results which further support record expression levels of the SARS-CoV-2 Receptor Binding Domain (RBD) antigen produced from Dyadic’s industrially proven proprietary & patented hyper-productive C1 gene expression platform. The RBD was produced at three grams per liter (3 g/l) in only five days.

Additionally, Dyadic highlighted how its C1 Rapid Recombinant Protein Manufacturing Platform can manufacture monoclonal antibodies (mAbs) more efficiently and faster than currently existing CHO (Chinese Hamster Ovary) expression platforms. Dyadic announced that it has expressed a SARS-CoV-2 mAb in collaboration with a biotech company who is developing promising new antibody cocktails to treat COVID-19 patients.

Dyadic’s CEO Mark Emalfarb commented: “The recent successful use of mAb cocktails for the treatment of COVID-19, revealed the potential for significant capacity and supply constraints in the manufacturing chain. Dyadic’s C1 gene expression platform offers a potential answer to these challenges because it can yield three to four times greater quantities of mAbs in the same timeframe as the current CHO cell production methods.

“While that is still not yet enough to meet anticipated global demand, it certainly is a significant step in potentially helping to ensure patients have greater access to medicines, and at a lower cost.”

Currently, the proprietary C1 expressed receptor binding domain (RBD) of the SARS-CoV-2 spike protein is being used in animal trials by seven research groups, governmental agencies and biopharma companies including the Israel Institute for Biological Research (IIBR) and a collaboration of European Union scientists that participated with Dyadic in the ZAPI program.

These institutions and companies are testing the C1 expressed RBD vaccine candidate(s) in animal trials on a stand-alone basis as well as testing the C1 RBD with nanoparticles and adjuvants. Dyadic currently expects up to 10 animal trials to be completed by the end of 2020.

Data generated by a number of these third parties confirmed that the C1 expressed RBD has the correct structure resulting in high binding and neutralizing capacity. Additionally, the recently concluded IIBR mice study shows that the C1 RBD has the potential to generate excellent immunogenicity responses with very high titers and neutralizing antibodies against the SARS-CoV-2 coronavirus.

Dyadic is open to applying its C1 gene expression platform for the development & manufacturing of biologic vaccines & drugs for third parties using their vaccine, antibody and therapeutic protein candidates for COVID-19 or otherwise.

Mark continued: “Our C1 technology can express high levels of proteins more rapidly at flexible commercial scales more affordably using single use or stainless-steel bioreactors. We believe that our C1 platform, developed initially for high-volume, low-cost industrial use, can enable affordable, regional production of vaccines, antibodies and other therapeutic proteins, which has driven a heightened interest in our C1 technology.”

About C1

Developed from a biosynthesized biopharmaceutical gene expression platform based on the fungus Thermothelomyces heterothallica (formerly Myceliophthora thermophila), the C1 microorganism, is a breakthrough that has the potential to significantly improve the production economies associated with processing today’s and tomorrows most advanced biologic medicines.

Because C1 enables the development and large-scale manufacture of low-cost proteins. it has the potential to be further developed into a safe, efficient expression system that can accelerate the development, lower the production costs and improve the performance of biologic vaccines and drugs at flexible commercial scales.

Dyadic is using the C1 technology and other technologies to conduct research, development and commercial activities for the development and manufacturing of human and animal vaccines and drugs, such as virus like particles (VLPs) and antigens, monoclonal antibodies, Fab antibody fragments, Fc-Fusion proteins, biosimilars, and other therapeutic proteins. Certain other research activities are ongoing which include the exploration of using C1 to develop and produce certain metabolites and other biologic products.

About Dyadic International, Inc.
Dyadic International, Inc. is a global biotechnology company pursuing research and development collaborations, licensing arrangements and other commercial opportunities with its partners and collaborators to leverage the value and benefits of these technologies in development and manufacture of biopharmaceuticals. In particular, as the aging population grows in developed and undeveloped countries, Dyadic believes the C1 technology may help bring biologic vaccines, drugs and other biologic products to market faster, in greater volumes, at lower cost, and with new properties to drug developers and manufacturers, and improve access and cost to patients and the healthcare system, but most importantly save lives.
