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. ...

Cancer Research UK, the world’s leading cancer charity, and Hummingbird Bioscience, an innovative systems-biology enabled biotechnology company, have announced a partnership to develop Hummingbird’s anti-HER3 antibody drug, HMBD-001, for the treatment of people with HER3 driven cancer.

Under the terms of the partnership, Cancer Research UK’s Centre for Drug Development will fund the programme, manufacture the clinical grade antibody and conduct a phase I clinical trial to evaluate drug safety, toxicity and efficacy.

Hummingbird will retain the rights to further advance the HMBD-001 programme and following completion of the trial, will have the option to acquire the rights to the clinical trial results to support further development of the antibody. If Hummingbird elect not to exercise their option, Cancer Research UK will have the right to take the programme forward in all indications.

The novel antibody, brought to Cancer Research UK through its Clinical Development Partnerships scheme, was discovered by Hummingbird using its Rational Antibody Discovery Platform.

The antibody targets the HER3 receptor, which when activated through binding to other cancer-associated proteins, turns on a strong signal that causes cancer cells to grow and divide.

This activation is common in multiple solid tumours, including breast, gastric, pancreatic, ovarian and lung cancers, and is also seen when cancers develop resistance to existing cancer therapies. HMBD-001 is the only anti-HER3 antibody in development that binds to the most critical region involved in HER3 activation, turning off this signal completely. Therefore, if successful, this new antibody could be used in the treatment of multiple cancers and be effective against drug resistant cancers.

Dr Nigel Blackburn, Cancer Research UK’s director of drug development, said: “We’re thrilled to be working with Hummingbird to fast track such a promising new antibody, through one of the most difficult stages of drug development.

“For many people with cancer, targeted treatments can work in the short term, but drug resistance sometimes leads to the eventual return of their tumour. We hope this antibody may be able to overcome a key mechanism of drug resistance and help us find new lasting ways to tackle the disease.”

Hummingbird’s antibody is distinct from other anti-HER3 agents currently in development, because it blocks all mechanisms through which HER3 can be activated, overcoming an intrinsic mechanism that has prevented previous HER3 therapeutics from working effectively.

The HER3 receptor is activated via a process called heterodimerisation, where HER3 combines with other proteins also linked to cancer growth, EGFR or HER2. This process can be aided by a ligand molecule called NRG1, which is at higher levels in patients with a specific genetic mutation.

When HER3 or its binding partners are overexpressed in cancer, excessive heterodimerisation can trigger tumour growth and lead to the spread of disease to other parts of the body. This process is also thought to contribute to some patient’s cancers becoming resistant to common cancer drugs, such as trastuzumab (Herceptin), which is used to treat breast cancer.

The binding position of HMBD-001 is unique and it is currently the only antibody that can efficiently block HER3 activation in both the presence and absence of the ligand, NRG1.

Dr Jerome Boyd-Kirkup, chief scientific officer at Hummingbird Bioscience, said: “We are excited and privileged to be working with the deeply experienced team at Cancer Research UK to develop HMBD-001 into the clinic.

“As an emerging drug discovery company, the funding and management support that Cancer Research UK will provide allows us to progress a potentially transformative new cancer therapy into patients as quickly and as safely as possible. This support also allows Hummingbird to focus on developing more desperately needed drugs against new targets using our Rational Antibody Discovery Platform.”

About Cancer Research UK’s Centre for Drug Development

Cancer Research UK has an impressive record of developing novel treatments for cancer. The Cancer Research UK Centre for Drug Development, formerly the Drug Development Office, has been pioneering the development of new cancer treatments for 25 years, taking over 140 potential new anti-cancer agents into clinical trials in patients. It currently has a portfolio of around 30 new anti-cancer agents in preclinical development, Phase I or early Phase II clinical trials. Six of these new agents have made it to market including temozolomide for brain cancer, abiraterone for prostate cancer and rucaparib for ovarian cancer. Two other drugs are in late development Phase III trials. This rate of success is comparable to that of any pharmaceutical company.

About Hummingbird Bioscience

Hummingbird Bioscience is an innovative biotech company, with facilities in Singapore, South San Francisco, California and Houston, Texas, focused on applying advances in systems biology to rapidly develop successful cancer therapeutics for patients with limited treatment options. Recognition of the importance of both tumor evolution and evasion of immune response as key “hallmarks of cancer” has provided a wide class of new drug targets. Building on these insights, Hummingbird is applying integrative genomics and proteomics to develop a comprehensive framework to systematically address the barriers to an effective anti-tumor response in every patient. Using its Rational Antibody Discovery Platform, a proprietary systems immunology and computational structural biology approach that enables precise targeting of epitopes and mechanisms of action on cancer-associated proteins, Hummingbird Bioscience has developed a pipeline of highly promising first and best-in-class oncology and immuno-oncology drugs. Within its pipeline, HMBD-001 (anti-HER3 antibody) and HMBD-002 (anti-VISTA antibody) are anticipated to start clinical trials in 2020. For more information on Hummingbird Bioscience.
