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. ...

Dupixent, the immunology favourite developed by Sanofi and Regeneron Pharmaceuticals, is still on the rise. It has received back-to-back approvals this year for the treatment of eosinophilic esophagitis and paediatric eczema, and now the IL-4/IL-13 inhibitor has achieved a late-stage victory demonstrating its ability to treat yet another type 2 inflammatory condition, this time affecting the skin.

Data from the late-stage Prime trial, also known as dupixent or dupilumab, substantially reduced pruritus and skin lesions after 24 weeks in prurigo nodularis, as per information provided by the partners at the 2022 annual congress of the European Academy of Dermatology and Venereology.

The antibody developed by Sanofi and Regeneron performed admirably in the second of two late-stage studies that served as the foundation for the partners’ FDA clearance application.

The FDA is expected to make a decision on Dupixent’s priority review in prurigo nodularis by September 30.

If it were approved for the persistent skin condition, dupixent would be the first medication especially authorised for prurigo nodularis. Topical steroids are the current gold standard of treatment. However, prolonged use of these drugs can have serious negative effects. In the U.S. and Europe, there are thought to be roughly 145,000 adults with prurigo nodularis, and many more individuals battle to manage their condition with topical medications, a Sanofi spokesman said via email.

In terms of dermatological conditions, prurigo nodularis may not be as well-known as atopic dermatitis or eczema, but it actually has one of the greatest impacts on patients’ quality of life, according to M.D., SVP and therapeutic area head of immunology and inflammation at Regeneron, Bola Akinlade, in a recent interview.

Additionally, the illness is frequently misinterpreted, said Naimish Patel, M.D., Sanofi’s SVP and global development leader for inflammation and immunity. People with prurigo nodularis frequently struggle with an unrelenting itch all the time, Patel added, which doctors sometimes feel is only in the patient’s head because they have long endured inadequate steroid therapy.

According to Patel, the prime data clearly demonstrates that all is entirely upside down. As per Patel and Akinlade, diagnoses are probably underreported, as is the case with many disorders for which there are few therapeutic choices. Sanofi and Regeneron anticipate that diagnosis data will increase should Dupixent become available for prurigo nodularis.

One will probably learn that many more patients may genuinely have prurigo nodularis, according to Akinlade.

At the 24-week point of the Prime trial, 60% of the Dupixent patient population, more than 3 times as many as those on placebo, saw clinically relevant decreases in itching from baseline, which was the study’s key success indicator. Compared to patients in the control cohort, 48% of patients using the medication developed by Sanofi and Regeneron had clear or almost clear skin.

According to an announcement from Sanofi and Regeneron, safety was largely comparable to Dupixent’s known safety characteristics in its various dermatology applications.

Sanofi and Regeneron released their first batch of delayed prurigo nodularis data from Dupixent’s Prime2 study in October 2021. Along with similar data on itch and skin clearance as the Prime results, Prime2 discovered that the antibody demonstrated larger improvements than a placebo in treating symptoms of anxiety and sadness. Sanofi and Regeneron are evaluating Dupixent in three additional skin disorders with type 2 inflammation, in addition to prurigo nodularis. These include chronic spontaneous urticaria, bullous pemphigoid, and atopic dermatitis in individuals as young as six months old, where Dupixent is approved in the U.S. and pending an EMA decision in that age range.

According to Regeneron’s Akinlade, the growth of Dupixent in a variety of illnesses driven by type 2 inflammation is only the beginning. Adding that Dupixent’s trip is still in mid-stream, Patel agreed.

On the company’s most recent second-quarter results call, Paul Hudson, chief executive of Sanofi, stated that Dupixent clearly remains the No. 1 contributor to their growth story. According to Sanofi at the time, Dupixent generated sales of 1.96 billion euros for the second quarter of 2022, an increase of 43.4% at constant currency. For Sanofi, which recently increased its peak sales estimate for the pill from 10 billion euros to even more than 13 billion euros (about $14.44 billion), the idea that Dupixent is just getting started is a recurrent theme. The possibility of increased sales may be boosted by forthcoming readouts on chronic obstructive pulmonary disease scheduled for release in 2019.

In the United States, Dupixent was first authorised in 2017 to treat eczema. Since then, it has received approval for three disorders across a range of age categories. Dupixent has had success in treating eosinophilic esophagitis, severe asthma, even in younger patients, and atopic dermatitis just this year.
