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.

A United States Food and Drug Administration advisory panel has voted in favour of approving GRAIL’s Galleri, positioning the multi-cancer early detection test for a potential landmark regulatory decision in the months ahead.

Panel Votes Across Three Key Dimensions

The ten voting members of the FDA’s Molecular and Clinical Genetics Devices advisory panel evaluated the GRAIL Galleri test across three separate votes, each addressing a distinct dimension of the product’s regulatory profile — safety, effectiveness, and overall benefit-risk assessment — specifically for screening adults aged 50 years and older for the early detection of multiple types of cancer.

The panel voted seven to two in favour of market approval, with one abstention, concluding that the test’s benefits outweighed its risks. The panel unanimously supported Galleri’s safety profile and voted six to four in support of its effectiveness.

How the Galleri Test Works

GRAIL submitted its pre-market approval application for the GRAIL Galleri test to the FDA on 29 January 2026. The test is designed to detect more than 50 types of cancer from a single blood draw. It works by identifying cancer-specific methylation patterns shared across many cancer types through the detection of chemical changes in fragments of cell-free DNA that break off from cancer cells. The test is intended to identify cancer before symptoms appear, including cancers that do not currently have recommended screening protocols in place.

Galleri secured breakthrough device designation from the FDA in 2018. Following the advisory panel’s vote, the FDA is expected to make its final decision on the pre-market approval application in the coming months.

GRAIL Chief Executive Officer Josh Ofman commented on the outcome: “The Galleri test was developed to improve the effectiveness and efficiency of our national cancer screening programme by adding multi-cancer early detection to recommended screening — helping find more cancers safely, when they may be easier and less costly to treat, and it still may be possible for a patient to receive treatment with curative intent.”

Ofman further stated that the panel’s vote reinforced the strength of Galleri’s clinical evidence. “We believe the panel’s recommendations reaffirm a high evidence bar that GRAIL has set for a multi-cancer early detection test,” he concluded.

Panel Endorsement Follows Mixed Results in NHS-Galleri Trial

The FDA panel’s endorsement arrives against the backdrop of a mixed year for the technology. In February, Galleri failed to meet its primary endpoint in a large United Kingdom National Health Service trial. Primary results from the NHS-Galleri trial were presented at the American Society of Clinical Oncology meeting in Chicago in May, with final results from the randomised trial of over 140,000 patients subsequently published in the New England Journal of Medicine on 22 September.

The NHS-Galleri trial sought to determine whether the test’s application within the NHS reduced the likelihood of a late-stage cancer diagnosis in an asymptomatic population. The test’s primary endpoint of a statistically significant Stage III and Stage IV reduction across 12 prespecified cancers was not met.

Despite this outcome, study investigators highlighted that adding annual MCED testing to standard-of-care cancer screening substantially increased screen-detected cancers, reduced Stage IV cancers, and reduced emergency presentations. The investigators suggested that integrating MCED testing into population screening programmes may help reduce late-stage cancer burden.

PATHFINDER 2 Study Findings and Ongoing REACH Study

Also at this year’s American Society of Clinical Oncology meeting, GRAIL presented findings from its 35,878-patient registrational PATHFINDER 2 study. Results indicated that adding Galleri to recommended screenings for breast, cervical, colorectal, and lung cancers — in line with United States Preventive Services Task Force A and B recommendations — led to a 6.5-fold increase in the number of cancers found through screening.

Separately, the GRAIL Galleri test is currently being evaluated in the ongoing United States-based REACH study, which is enrolling 50,000 Medicare beneficiaries who receive usual care alongside a Galleri test. The study includes a matched comparator arm of beneficiaries who receive usual care alone, with the objective of assessing the test’s real-world clinical impact.
