Patients' attitudes toward the donation of biological materials for the derivation of induced pluripotent stem cells

Anticipating in vitro gametogenesis: Hopes and concerns for IVG among diverse stakeholders

In vitro gametogenesis (IVG), the reconstitution of germ cell development in vitro, is an emerging stem cell-based technology with profound implications for reproductive science. Despite researchers' long-term goals for future clinical applications, little is currently known about the views of IVG held by the stakeholders potentially most affected by its introduction in humans. We conducted focus groups and interviews with 80 individuals with lived experience of infertility and/or LGBTQ+ family formation in the US, two intersecting groups of potential IVG users. Respondents expressed hope that IVG would lead to higher reproductive success than current assisted reproductive technology (ART), alleviate suffering associated with ART use, and promote greater social inclusion, while expressing concerns predominantly framed in terms of equity and safety. These findings underscore the importance of sustained engagement with stakeholders with relevant experience to anticipate the implications of IVG for research and clinical translation.

Give heart cells a beat: An interactive museum exhibit that synchronizes stem cell-derived cardiomyocytes to visitors' heartbeat

Science museums play an important role in science education, engaging the public with science concepts and building support for scientific research. Here, we describe Give Heart Cells a Beat, an interactive exhibit that lets museum visitors synchronize the beating of live stem cell-derived cardiomyocytes to their own heart rate in real time. The beat rate of cells accurately matched the beat rate of visitors and responded dynamically to changes such as exercise. Visitor evaluation revealed that engagement with the specimen prompted curiosity in heart biology and stem cells. Give Heart Cells a Beat is the product of a close collaboration between a museum and an academic research laboratory, and to our knowledge, it is the first interactive exhibit to use live human heart cells. We hope this exhibit serves as an example for the implementation of stem cell technology in informal science education and inspires future relationships between academia and public science venues.

Post-identifiability in changing sociotechnological genomic data environments

Data practices in biomedical research often rely on standards that build on normative assumptions regarding privacy and involve 'ethics work.' In an increasingly datafied research environment, identifiability gains a new temporal and spatial dimension, especially in regard to genomic data. In this paper, we analyze how genomic identifiability is considered as a specific data issue in a recent controversial case: publication of the genome sequence of the HeLa cell line. Considering developments in the sociotechnological and data environment, such as big data, biomedical, recreational, and research uses of genomics, our analysis highlights what it means to be (re-)identifiable in the postgenomic era. By showing how the risk of genomic identifiability is not a specificity of the HeLa controversy, but rather a systematic data issue, we argue that a new conceptualization is needed. With the notion of post-identifiability as a sociotechnological situation, we show how past assumptions and ideas about future possibilities come together in the case of genomic identifiability. We conclude by discussing how kinship, temporality, and openness are subject to renewed negotiations along with the changing understandings and expectations of identifiability and status of genomic data.

Prospective donors' perspectives on hematopoietic cell donation for cell and gene therapy research and development

Aim: To explore prospective donors' attitudes and perceptions toward donating hematopoietic stem cells (HSCs) for novel treatments research and development (R&D). Methods: A survey was launched by Anthony Nolan (AN) to assess prospective donors' willingness to donate HSCs for novel therapies R&D, and their degree of comfort with the AN collaborating with and receiving payment from external organizations. Results: Most participants (87%) were willing to donate for novel treatment R&D and were comfortable with AN collaborating with external organizations and receiving payment (91% and 80%, respectively). Conclusion: Results reveal an overall positive response toward donating HSCs for R&D. These findings can support stakeholders and policymakers in outlining donation practices that uphold donors' safety and welfare.

Identification and Re-consent of Existing Cord Blood Donors for Creation of Induced Pluripotent Stem Cell Lines for Potential Clinical Applications

We aim to create a bank of clinical grade cord blood-derived induced pluripotent stem cell lines in order to facilitate clinical research leading to the development of new cellular therapies. Here we present a clear pathway toward the creation of such a resource, within a strong quality framework, and with the appropriate regulatory, government and ethics approvals, along with a dynamic follow-up and re-consent process of cord blood donors from the public BMDI Cord Blood Bank. Interrogation of the cord blood bank inventory and next generation sequencing was used to identify and confirm 18 donors with suitable HLA homozygous haplotypes. Regulatory challenges that may affect global acceptance of the cell lines, along with the quality standards required to operate as part of a global network, are being met by working in collaboration with bodies such as the International Stem Cell Banking Initiative (ISCBI) and the Global Alliance for iPSC Therapies (GAiT). Ethics approval was granted by an Institutional Human Research Ethics Committee, and government approval has been obtained to use banked cord blood for this purpose. New issues of whole-genome sequencing and the relevant donor safeguards and protections were considered with input from clinical genetics services, including the rights and information flow to donors, and commercialization aspects. The success of these processes has confirmed feasibility and utility of using banked cord blood to produce clinical-grade iPSC lines for potential cellular therapies.

The Promoting Equity in Stem Cell Genomics Survey

Aim: This study aimed to determine knowledge and attitudes toward induced pluripotent stem cell technology and biobanking. Methods: A survey instrument was developed to determine individuals' knowledge of and attitudes toward these technologies. Results: Results from 276 ethnically diverse participants who took the online survey demonstrated significant associations (p ≤ 0. 05) in knowledge by ethnicity and race regarding properties of stem cells, different types of stem cells and previous sample donation behavior. Significantly more Whites 39% (n = 53) compared with Blacks or African-Americans 19.2% (n = 14) had previous knowledge of induced pluripotent stem cells (χ² = 8.544; p = 0.003) Conclusion: Overall, White race was associated with greater knowledge about stem cells and biobanks and greater willingness to donate samples for future research.

A scoping review of patient and public perspectives on cell and gene therapies

Aim: The development and introduction of cell and gene therapies presents complex social and economic issues. Fully addressing these challenges requires engagement with patients and the public. Materials & methods: A systematically conducted scoping review was undertaken to gauge current patient and public knowledge and perspectives, and as such inform requirements for future research, education and engagement activities. Results: A heterogeneous collection of 35 studies were identified. Levels of knowledge among patients and the public were extremely variable. Studies indicated general acceptance of therapies. Conclusion: The review identified the need for tailored educational activities, and in particular the importance of addressing misconceptions. There is also a need for robust qualitative research considering perspectives on current and forthcoming licensed therapies.

Content and Method of Information for Participants in Clinical Studies With Induced Pluripotent Stem Cells (iPSCs)

Research with induced pluripotent stem cells (iPSCs) involves specific ethical challenges, which should be addressed in the informed consent process. Up to now, little concern has been paid to the practice of information in iPSC-clinical studies. In order to fill this research gap, we have searched the documentation of the Research Ethics Committee at Ulm University from the years 2007 to 2019. In our previous research, we have identified 11 items for evaluation of the process of information in iPSC research. We used these items to analyze content and form of information provided for participants in the iPSC studies conducted at Ulm University and Ulm University Hospital in Germany. All analyzed studies provide general information regarding the study's aim, method, and collection of donor's personal data and specimen. The information for participants in these studies adheres to general guidelines for research involving human subjects; however, in several areas fails to take into account the specific nature of research with iPSCs. The majority of analyzed studies fail to provide information about possible individual consequences connected with genetic research, such as the possibility of re-identification of the donor or incidental findings acquired during research. Missing is also information about the possibility of future studies involving reproductive research or transplantation of cells and organs. The donor information process in all analyzed studies is conducted in form of the information sheet and oral information. The results of our research show that the process of informed consent in iPSC research should be updated as new developments emerge in this area. However, comprehension of information should not be jeopardized through information overload. Effective communication of essential information requires improved information methods tailored to the needs of participants, such as video animations, interactive consent modules or social media instruments.

Patient and public perspectives on cell and gene therapies: a systematic review

Cell and gene therapies offer opportunities for treating disease with potential to restore function, and cure disease. However, they are not without risk and pose complex logistical, economic, ethical and social challenges for health systems. Here we report our systematic review of the current evidence on patient and public knowledge and perspectives of cell and gene therapies, to inform future research, education and awareness raising activities. We screened 10,735 titles and abstracts, and evaluated the full texts of 151 publications. The final selection was 35 publications. Four themes were generated from the narrative synthesis of the study findings namely: (1) Knowledge and understanding of cell and gene therapies, (2) Acceptance of cell and gene therapies (3) Understanding of risk and benefits of therapy, and (4) Information needs and current sources of information. As potential funders or future recipients, it is important that the public and patients are aware of these therapies, understand the issues involved, and can contribute to the debate. This review highlights the need for appropriate patient and public education on the various aspects of cell and gene therapies. High quality studies exploring patient and public opinions and experiences of cell and gene therapy are required. Patient and public perceptions of these therapies, alongside evidence of clinical and cost-effectiveness, will be central to their uptake and use.

Research, Digital Health Information and Promises of Privacy: Revisiting the Issue of Consent

The obligation to maintain the privacy of patients and research participants is foundational to biomedical research. But there is growing concern about the challenges of keeping participant information private and confidential. A number of recent studies have highlighted how emerging computational strategies can be used to identify or reidentify individuals in health data repositories managed by public or private institutions. Some commentators have suggested the entire concept of privacy and anonymity is “dead”, and this raises legal and ethical questions about the consent process and safeguards relating to health privacy. Members of the public and research participants value privacy highly, and inability to ensure it could affect participation. Canadian common law and legislation require a full and comprehensive disclosure of risks during informed consent, including anything a reasonable person in the participant or patient’s position would want to know. Research ethics policies require similar disclosures, as well as full descriptions of privacy related risks and mitigation strategies at the time of consent. In addition, the right to withdraw from research gives rise to a need for ongoing consent, and material information about changes in privacy risk must be disclosed. Given the research ethics concept of “non-identifiability” is increasingly questionable, policies based around it may be rendered untenable. Indeed, the potential inability to ensure anonymity could have significant ramifications for the research enterprise.

Donor information in research and drug evaluation with induced pluripotent stem cells (iPSCs)

Background

The discovery of induced pluripotent stem cells (iPSCs) opened the possibilities for reprogramming cells back to a pluripotent state. Because of no apparent ethical issues connected with donation and derivation of biomaterial, iPSCs are considered as a research alternative to ethically highly disputed human embryonic stem cells (hESCs). However, the unique character of iPSCs leads to numerous ethical considerations, which mainly concern the issue of donor information and consent for the use of biospecimen in research and drug evaluation.

Methods

For the purpose of this analysis, we conducted a review of the literature in the PubMed/MEDLINE and Web of Science databases. The search algorithm led to the identification of 1461 results. After removing duplicates and screening of title and abstract, 90 articles were found to be relevant to the study’s objective. Full texts of these articles were apprised and 62 articles were excluded at this step for not properly addressing the study’s objective. In the final step, 28 articles were included in the analysis. Analyzed were both research and non-research manuscripts published in peer-reviewed journals.

Results

In the case of iPSC research, the information process should be guided by general frameworks established for research on human subjects but also by specific characteristics of iPSCs. We determined four main domains and 12 thematic subdomains that should be included in donor information. Our results show that majority of authors agree to the content of information with regard to the areas of general information, storage of cells, and protection of privacy. Two main issues that are discussed in the literature are donor’s consent for use in future studies and the process of donor information.

Conclusions

Given the unique character of iPSCs and the possibility of their various uses in the future, the content of donor information should contain specific information central to iPSC research. Effective methods of communicating information to donors should combine written and oral information with the possible use of multimedia.

Secondary Use of Patient Tissue in Cancer Biobanks

BACKGROUND

As scientific techniques evolve, historical informed consent forms may inadequately address modern research proposals, leading to ethical questions regarding research with archived biospecimens.

SUBJECTS, MATERIALS, AND METHODS

We conducted focus groups among patients with cancer recruited from Massachusetts General Hospital to explore views on medical research, biobanking, and scenarios based on real biospecimen research dilemmas. Our multidisciplinary team developed a structured focus group guide, and all groups were recorded and transcribed. Transcripts were coded for themes by two independent investigators using NVivo software.

RESULTS

Across five focus groups with 21 participants, we found that most participants were supportive of biobanks and use of their own tissue to advance scientific knowledge. Many favor allowing research beyond the scope of the original consent to proceed if recontact is impossible. However, participants were not comfortable speaking for other patients who may oppose research beyond the original consent. This was viewed as a potential violation of participants' rights or interests. Participants were also concerned with a "slippery slope" and potential scientific abuse if research were permitted without adherence to original consent. There was strong support for recontact and reconsent when possible and for the concept of broad consent at the time of tissue collection.

CONCLUSION

Our participants support use of their tissue to advance research and generally support any productive scientific approach. However, in the absence of broad initial consent, when recontact is impossible, a case-by-case decision must be made regarding a proposal's potential benefits and harms. Many participants support broad use of their tissue, but a substantial minority object to use beyond the original consent.

IMPLICATIONS FOR PRACTICE

For prospective studies collecting tissue for future research, investigators should consider seeking broad consent, to allow for evolution of research questions and methods. For studies using previously collected tissues, researchers should attempt recontact and reconsent for research aims or methods beyond the scope of the original consent. When reconsent is not possible, a case-by-case decision must be made, weighing the scientific value of the biobank, potential benefits of the proposed research, and the likelihood and nature of risks to participants and their welfare interests. This study's data suggest that many participants support broad use of their tissue and prefer science to move forward.

Broad Consent for Research on Biospecimens: The Views of Actual Donors at Four U.S. Medical Centers

Commentators are concerned that broad consent may not provide biospecimen donors with sufficient information regarding possible future research uses of their tissue. We surveyed with interviews 302 cancer patients who had recently provided broad consent at four diverse academic medical centers. The majority of donors believed that the consent form provided them with sufficient information regarding future possible uses of their biospecimens. Donors expressed very positive views regarding tissue donation in general and endorsed the use of their biospecimens in future research across a wide range of contexts. Concerns regarding future uses were limited to for-profit research and research by investigators in other countries. These results support the use of broad consent to store and use biological samples in future research.

Mini-guts in a dish: Perspectives of adult Cystic Fibrosis (CF) patients and parents of young CF patients on organoid technology

BACKGROUND

Organoid technology enables the cultivation of human tissues in a dish. Its precision medicine potential could revolutionize the Cystic Fibrosis (CF) field. We provide a first thematic exploration of the patient perspective on organoid technology to set the further research agenda, which is necessary for responsible development of this ethically challenging technology.

METHODS

23 semi-structured qualitative interviews with 14 Dutch adult CF patients and 12 parents of young CF patients to examine their experiences, opinions, and attitudes regarding organoid technology.

RESULTS

Four themes emerged: (1) Respondents express a close as well as a distant relationship to organoids; (2) the open-endedness of organoid technology sparks hopes and concerns, (3) commercial use evokes cautiousness. (4) Respondents mention the importance of sound consent procedures, long-term patient engagement, responsible stewardship, and stringent conditions for commercial use.

CONCLUSIONS

The precision medicine potential of organoid technology can only be realized if the patient perspective is taken adequately into account.

Examining Provisions Related to Consent in the Revised Common Rule

The long-standing overarching policy governing research with human subjects conducted and supported by most federal agencies and departments in the United States, known as the Common Rule, has recently been revised, with most requirements slated to become effective in 2018. Although there are multiple alterations to the current regulations, some of the most significant changes aim to enhance consent for research. While some of the particular provisions in this regard will be easy to apply and promise to help meet this goal, others may be more challenging to implement despite their intuitive appeal. In this article, I examine some of the provisions in the revised Common Rule that relate to consent: (1) new required consent elements; (2) the goal of comprehension in the consent process; (3) consent forms; and (4) broad consent. By raising issues about these provisions now and suggesting possible ways to overcome their potential shortfalls, the hope is that future efforts can be taken to help clarify and appropriately implement them.

Voting on Embryonic Stem Cell Research: Citizens More Supportive than Politicians

As the public debate over stem cell research continues, the observable voting behaviour in Switzerland offers a unique opportunity to compare the voting behaviour of politicians with that of voters. By analysing the outcomes of a referendum on a liberal new bill regulating such research, we reveal an about 10 percentage point lower conditional probability of the bill being accepted by politicians than by voters. Whereas the behaviour of politicians is driven almost entirely by party affiliation, citizen votes are driven not only by party attachment but also by church attendance. Seldom or never attending church increases the probability of bill acceptance by over 15 percentage points, while supporting the Liberal Party and the Social Democratic Party instead of the Christian Democratic Party makes supporting the bill more likely for voters, suggesting that religious observance is important. The observance of these tendencies in Switzerland—an environment that promotes discussion through direct democratic rights—strongly suggests that citizens see the benefits of stem cell research.

Participant understanding and recall of informed consent for induced pluripotent stem cell biobanking

The ability to generate human induced pluripotent stem cells (iPSCs) has opened new avenues for human disease modelling and therapy. The aim of our study was to determine research participants' understanding of the information given when donating skin biopsies for the generation of patient-specific iPSCs. A customised 35-item questionnaire based on previous iPSC consent guidelines was sent to participants who had previously donated samples for iPSC research. The questionnaire asked pertinent demographic details, participants' motivation to take part in iPSC research and their attitudes towards related ethical issues. 234 participants were contacted with 141 (60.3 %) complete responses received. The median duration between recruitment and follow-up questioning was 313 days (range 10-573 days). The majority of participants (n = 129, 91.5 %) believed they understood what a stem cell was; however, only 22 (16.1 %) correctly answered questions related to basic stem cell properties. We found no statistically significant difference in responses from participants with different levels of education, or those with a health sciences background. The poor understanding amongst participants of iPSC research is unlikely to be unique to our study and may impact future research if not improved. As such, there is a need to develop an easily understood yet comprehensive consent process to ensure ongoing ethical progress of iPSC biobanking.

Global strategic partnerships in regenerative medicine

The approach to research and development in biomedical science is changing. Increasingly, academia and industry seek to collaborate, and share resources and expertise, by establishing partnerships. Here, we explore the co-development partnership landscape in the field of regenerative medicine, focusing on agreements involving one or more private entities. A majority of the largest biopharmaceutical companies have announced strategic partnerships with a specific regenerative medicine focus, signifying the growth and widening appeal of this emerging sector.

The DISCUSS Project: Revised Points to Consider for the Derivation of Induced Pluripotent Stem Cell Lines From Previously Collected Research Specimens

Human somatic cell reprogramming is a leading technology for accelerating disease modeling and drug discovery. The Deriving Induced Stem Cells Using Stored Specimens (DISCUSS) project is a consensus-building initiative designed to consider how human somatic cells obtained under general biomedical research protocols can be used in induced pluripotent stem cell (iPSC) derivation. We previously published a draft list of points to consider for the use of previously collected specimens in iPSC research and then initiated a structured feedback and comment process. Here, we present a summary of this feedback and revised list of points to consider.

Identifiability and privacy in pluripotent stem cell research

Data sharing is an essential element of research; however, recent scientific and social developments have challenged conventional methods for protecting privacy. Here we provide guidance for determining data sharing thresholds for human pluripotent stem cell research aimed at a wide range of stakeholders, including research consortia, biorepositories, policy-makers, and funders.
