Introduction

Biobank is the repository that stores human biological materials and associated data. Their advent in science and technology has seen scientists entering a new age in biotechnology research.¹ The field of medical research has witnessed a revolutionary shift with the rise of biobanks. A well-established biobank accelerates health research as it exploits state-of-the-art genetics together with big data sets, coupled with individual clinical data. It offers complex and powerful studies on a remarkable scale for understanding diseases, developing novel therapies and improving human health. They serve as a treasure trove for researchers, allowing them to identify genetic and biological markers associated with various conditions, track disease progression, and test the efficacy of new treatments. Unlocking the potential of the biobanks hinges on a critical yet delicate balance and the paramount concerns are needed for robust research against the fundamental rights of patients, consent, privacy, and data ownership. The individual’s contribution to the biobanks must be valued and it is imperative to ensure these are used ethically and responsibly. This article delves into the intricate world of legal frameworks for biobank patient protections, and ethical considerations surrounding biobanking, highlighting potential risks like breaches of confidentiality and misuse of biospecimens, and aims to illuminate the path towards robust legal frameworks that foster groundbreaking research while safeguarding the rights of individuals who contribute to biobanks.

Ethical considerations

The main challenge in the management of the biobank is to identify ways to protect the fundamental rights of the participants who provide samples, and data while fostering the public interest in carrying out lawful and ethical medical research that maximises access to the resource. To remain sustainable, the biobanks must depend on continual public, political and commercial support.² In this complex world of medical advancement, a biobank is a powerful player needing to address ethical considerations as much as possible.

Privacy

In the biobanks different types of privacy have been articulated, it is accepted that the biobanks raise several privacy concerns, including fear of misuse of personal information, stigmatisation and intrusion into private life.³ In this context, the individuals have the right to ask for informed consent before participating in research as donors, they also have the right to have their specimen anonymized to prevent unauthorised identification to maintain confidentiality and most importantly the right to withdraw at any stage if they wish.  Also, the individual’s interest in controlling genetic identity should be upheld to protect against discrimination.⁴ One technical solution to protect individual privacy has been to enhance confidentiality by removing personal identifiers linked to the encoded data. if a serial number or other code is attached to data as a key then this needs to be held elsewhere.  

Informed Consent

Informed Consent operates on the principle of protecting the participant’s freedom of choice and privacy. The importance of obtaining consent from research participants is stressed both at the international and national level and is one of the fundamental principles. World Medical Association’s Helsinki Declaration states:

In any research on human beings, each potential subject must be adequately informed of the aims, methods, anticipated benefits and potential hazards of the study and the discomfort it may entail.⁵

However, consent alone would not ensure that all of the interests of the participants are protected, and biobanks require additional policies for ethical data access to prevent misuse of an individual’s data. Obtaining informed consent is crucial, this process must be transparent, allowing patients to understand the nature of biobanking, the potential uses of their samples and data, and the associated risks. This includes the possibility of future research beyond the scope initially envisioned.

Data access and knowledge sharing

Biobanks contain both samples and associated identifiable personal data. The risk of individual identification and possible privacy breaches are heightened when data and samples are combined.⁶ The central question around data access is whether the data access request is necessary and compatible with robust privacy protection or if it compromises privacy interests and is unjustifiable. Once access is accepted to be in the public interest, the priority for biobanking is how to share data rather than whether data should be shared at all. Expert data access committees may be established to review access applications in an accountable and transparent way.⁷ Data access policies can be drafted to outline the access requirements for the biobank data, mentioning criteria for the assessment of the researcher’s proposals, affiliations and purposes. If successfully granted access, researchers must  agree to conditions of use, which are often contained in contractual or Material Transfer Agreements (MTA)

There is also a growing acceptance that the merits of biobanking will only be fully realised if resources can ‘link up and learn from each other, ideally on a global scale.’ There is an international collaborative effort to establish a data-sharing code of conduct for international genomic research; one of it is the European Biobanking and Biomolecular Resources Research Infrastructure (BBMRI) intended to develop governance structures for biobank networks.^8,9 

Ownership and rights

Determining the ownership of biospecimens and data collected in biobanks is a thorny issue. Do the participants retain any ownership rights, or do they cede control upon donation? Similarly, how should data be shared with researchers and commercial entities? Balancing the need for open access to facilitate research with fair compensation for patient contributions remains a challenge. Some of the solutions are described as potential models for biobank governance. They include Winickoff’s own ‘Charitable Trust Model’, as well as other models of benefit sharing with research donors (for example by contract, regulation, taxation and ethical standards) and models for participant involvement and engagement in biobanking such as the ‘Stakeholder Model’ proposed by Hunter and Laurie.¹⁰

Legal frameworks for patient protections

International guidelines

Universal Declaration on Bioethics and Human Rights (UNESCO, 2005)

As a non-binding instrument, the declaration must be incorporated by UNESCO’s member states into their national laws, regulations or policies. The first such document to set global standards in biological and medical ethics, it merges bioethics with human rights. The declaration establishes core principles for bioethics, including informed consent, privacy, and respect for human dignity.¹¹

Council for International Organizations of Medical Sciences (CIOMS) International Ethical Guidelines for Biomedical Research Involving Human Subjects (2016)

This guideline relates mainly to ethical justification and scientific validity of research, ethical review, consent, choice of control in clinical trials, confidentiality, compensation, and obligations of sponsors to provide healthcare services.

Regional initiatives

Council of Europe Convention on Human Rights and Biomedicine (1997)

It is the first international treaty focused on bioethics. This convention, ratified by several European nations, sets legal standards for biobanking practices. It is a framework convention aiming to protect dignity, identity without discrimination, respect for integrity and fundamental freedom.¹²

Declaration of the Asian Bioethics Forum (2005)

Drafted by Asian nations, emphasises the importance of respecting cultural values and ensures equitable access to benefits derived from biobanking research. While not legally binding, it promotes responsible biobanking practices in the Asian region.

National Laws

Establishing biobanking-specific laws or regulations is on the sovereignty of an individual country. n the United Kingdom, a leader in genomics research, with the presence of numerous types of biobanks there is no specific statute or a single piece of legislation for medical research on human beings. On the contrary, it is governed by multiple statutory laws, common regulations, and guidance documents.¹³

Legal and regulatory privacy framework

The constitutional framework provides the basis for the law and regulation of privacy in biobanking in the United Kingdom.

Fundamentally, a distinction is maintained across UK legislation between human specimens and data, and this determines the appropriate regulatory framework for each. The Human Tissue Act 2004 (HTA) and Data Protection Act 1998 (DPA) regulate the storage and usage of human specimens, personal information and genetic information.

The complexity of the UK position is largely because the law that applies to biomedical research at the European level spans several areas of law, such as data protection, privacy and tissue regulation as well as medical research regulations. Depending upon the context and key statutes the other relevant acts are,  

• Human Rights Act 1998
• Mental Capacity Act, 2005
• National Health Service Act, 2006
• Access to Health Records Act, 1990
• Health and Social Care Act, 2012

Policy Guidance, role of courts and governing bodies

In the absence of specific legislation, there are several guidance documents and codes of practice for biobank governance created by large funding bodies in the UK, such as the Medical Research Council or the Wellcome Trust charity. These documents are not binding in UK law, adherence to them is done with the intent to demonstrate good practice and compliance. As of now, there are no reported cases that are related specifically to biobanking. Before 2011 no one body was responsible for the oversight of the research process, the advent of the Human Research Authority protects and promotes the interests of patients and the public, providing guidance and accreditation for research ethics committees.

What are the future considerations needed to strengthen the legal frameworks?

Existing legal frameworks lay the groundwork for biobank patient protection, there's room for improvement.

Clarity, specificity and need for a separate law

There is a lack of clarity in some areas of the current framework about the usage of specimens and private information for research purposes, which is very much needed for biobanking and upholding patient rights. Dedicated biobanking law could offer clear definitions for key terms like informed consent, anonymization, and broad consent which would provide a stronger foundation for ethical research practices.

Facilitating the framework for dynamic, adaptable, and periodic review 

Technologies and research practices are evolving constantly, legal frameworks need to be dynamic and adaptable to accommodate these advancements. Periodic review and updates are essential to ensure the legal landscape keeps pace with scientific progress to ensure it remains effective in addressing emerging challenges and ethical considerations.

Addressing informed consent challenges

One of the most controversial aspects of biobanking has been the use of broad consent, i.e. consenting to undefined future research uses of donations, rather than the more conventional informed consent. The complexities in the section of informed consent, particularly concerning future research use and incidental findings, require careful consideration. Legal frameworks could define different tiers of consent (broad vs. specific) and establish clear guidelines for researchers regarding communication with patients about potential future research directions.¹⁴

Addressing Data sharing and ownership challenges 

Inherent to the challenges of privacy and data access raised by biobanks are questions of ownership and commercialization. Researchers are also under pressure to commercialise and translate their work for funding agencies. It has been argued, ‘It is not unreasonable to view the overall purpose of biobanks is to enable the development of translational outcomes intended to benefit patients.¹⁵ Developing clear mechanisms for benefit-sharing with patients who contribute to biospecimens is crucial. This could involve royalty structures or patents for commercially successful discoveries.¹⁶ Legal frameworks need to strike a balance between facilitating data sharing for research and ensuring fair compensation for patients who contribute their biological samples. Establishing oversight bodies and outlining penalties for violations are crucial deterrents against unethical practices and ensure adherence to patient protections.

Harmonising national guidelines with international standards

Aligning national biobanking guidelines with established international frameworks like the CIOMS guidelines and the UNESCO Declaration on Bioethics and Human Rights would demonstrate the country's commitment to ethical research practices and facilitate international collaboration in biobanking research. Building public trust in biobanking is essential. The legal framework should promote transparency and public engagement by encouraging open communication about biobanking practices and data security measures.

Conclusion

The value of biobanks in the health research arena must be appreciated by scientists, the public and policymakers. The use of biobank assets will lead to benefits in the diagnosis and treatment of numerous diseases. This should be encouraged while considering the associated ethical, legal and social issues and working towards a balance between these two requirements. The importance of public trust and confidence in this equation must not be underestimated. Biobanking holds immense potential for revolutionising healthcare. However, unlocking this potential hinges on striking a delicate balance between scientific progress and patient rights. By fostering a legal environment that prioritises both robust research and patient protection, we can ensure that biobanking thrives as a force for good. With strong ethical foundations, biobanks can serve as a powerful tool for advancing medical knowledge, developing new therapies, and ultimately improving human health for future generations.
