The US Direct-to-Consumer Marketplace for Autologous Stem Cell Interventions.

Hundreds of businesses and clinics in the United States are engaged in direct-to-consumer marketing of unproven and unlicensed stem cell-based interventions. This essay provides an overview of this marketplace, examines advertising techniques companies use to draw clients and legitimate marketing claims, and summarizes the roles the Food and Drug Administration (FDA) and other agencies are supposed to play in regulating the direct-to-consumer marketplace for stem cell interventions. The essay also reviews federal regulations, describes how many businesses selling purported "stem cell treatments" appear to violate these standards, and considers ethical issues and harms associated with widespread promotion of unapproved stem cell products.

Between the Local and the Global: Evaluating European regulation of stem cell regenerative medicine.

Current European regulations hinder the compilation of the evidence that would be required to bring safe and effective autologous stem cell-based interventions (SCBIs) into standard clinical care. European agencies have expanded their regulations to cover all new SCBIs and research. They establish demanding conditions for cell retrieval, processing, and application. Drawing on empirical sociological findings from the implementation of the first phase III stem cell clinical trial in Europe, this article examines ethical problems effected by that policy, such as that the costs of bringing treatments to market means new autologous SCBIs may remain untested and that this plays in favor of the growing direct-to-consumer market, and that the research pathways in regenerative medicine and the role of clinician-scientists in developing new treatments are restricted, because the regulations are biased to enable specific SCBIs that are of interest to industry. This situation contradicts the moral and social concerns in favor of new treatments and patient interests, which the regulations supposedly safeguard. To align the aims and effects of policy better, European regulatory authorities should reconfigure their regulations to advance a fair and effective governance regime that allows pursuit of all promising SCBIs.

Challenges in the Regulation of Autologous Stem Cell Interventions in the United States.

The direct-to-consumer marketing of stem cells for unproven therapeutic uses has grown rapidly in the United States in recent years. This development is surprising since the marketing and distribution of human cell-based medical products is stringently regulated in the US. This essay describes ambiguities, gaps, and inconsistencies in the current regulatory system that have enabled such businesses to thrive. In addition to directly challenging the authority of the Food and Drug Administration (FDA) over autologous cell-based products in the courts, stem cell marketing firms have also identified and exploited regulatory loopholes, such as the same surgical procedure exception, which exempts from FDA oversight human cell-based products that are harvested and reimplanted in a single procedure. Many businesses also advertise stem cell clinical studies on a pay-to-participate basis, which requires patients to pay large sums to enroll in clinical research. This business model not only shifts many of the cost and risks of medical experimentation from providers to patients but may also indemnify sellers from fraud litigation. Lastly, stem cell advertisers borrow heavily from the language and concepts of science-based medicine in their marketing. The inaccurate promotion of autologous stem cell injections as a form of "personalized" medicine lends a veneer of credibility and precision that may encourage patients to undergo procedures of uncertain effectiveness and to sympathize with stem cell businesses in their efforts to evade oversight.

Conditional Approvals for Autologous Stem Cell-Based Interventions: Conflicting norms and institutional legitimacy.

Demands from patients, health-care professionals, and industry to streamline the market approval process for promising new therapies has prompted the introduction of programs that can provide more rapid access to stem cell-based products before evidence of safety and efficacy has been demonstrated in clinical trials. These products may be approved for marketing under "conditional authorizations," while uncertainty around safety and efficacy is reduced through the collection of clinical data in observational trials or registries. The rationale for conditional approval programs assumes that patients with unmet medical needs will benefit with rapid access to novel stem cell therapies. It also assumes that data gathered in actual clinical contexts is inherently better at reducing uncertainty than conventional clinical trial methods of demonstrating safety and efficacy. These assumptions may be overly optimistic and do not account for the broader societal burdens of prematurely releasing high-cost therapies with uncertain safety risks and benefits on to health-care markets. This essay focuses on the introduction of conditional approval programs for autologous somatic stem cell therapies and argues that these programs may conflict with, and potentially undermine, the normative commitments of regulatory agencies charged with promoting population health and protecting vulnerable groups from harm and exploitation. It concludes with suggestions of how programs designed to accelerate access to potentially helpful but experimental interventions could be reconfigured to be more equitable.

Vulnerabilities and the Use of Autologous Stem Cells for Medical Conditions in Australia.

Australia has a booming market of unproven autologous stem cell- based interventions (SCBIs) for a wide range of medical conditions. Multiple SCBIs are provided in private practices outside of formal clinical trials. Some defend the provision of unproven SCBIs on grounds of patient choice. This essay interrogates this argument for patient choice and explores patients' vulnerabilities in clinical practice with autologous SCBIs. While all patients are inherently vulnerable, the regulatory framework for autologous stem cells in Australia exacerbates the problems associated with inherent vulnerabilities and generates situational and pathogenic vulnerabilities. A just state ought to implement regulatory measures that mitigate vulnerabilities and foster patients' autonomy.

The Need for Beneficence and Prudence in Clinical Innovation with Autologous Stem Cells.

The term innovation is frequently used as a justification for allowing clinicians to offer unproven autologous stem cell-based interventions (SCBIs) to their patients. Proponents of this kind of innovation (which we refer to as "clinical innovation") argue that physicians should be free to administer whatever interventions they choose, and informed consumers should be free to receive them. This article refutes the notion that clinician autonomy and consumer demand are a sufficient justification for offering patients unproven autologous SCBIs. We argue that, while clinician and consumer preferences need to be taken seriously, access to unproven SCBIs can only be fully justified when it is based on a commitment to beneficence and prudence. We also argue that there is a need for a clearer distinction between the definition of clinical innovation with autologous stem cells, which is morally neutral, and its justification, which entails a commitment to beneficence and prudence. Finally, we argue that regulation of clinical innovation with autologous stem cells needs to be based on a bioethics of innovation that attends to beneficence and prudence alongside other ethical principles.

Ethical and Regulatory Challenges with Autologous Adult Stem Cells: A Comparative Review of International Regulations.

Cell and tissue-based products, such as autologous adult stem cells, are being prescribed by physicians across the world for diseases and illnesses that they have neither been approved for or been demonstrated as safe and effective in formal clinical trials. These doctors often form part of informal transnational networks that exploit differences and similarities in the regulatory systems across geographical contexts. In this paper, we examine the regulatory infrastructure of five geographically diverse but socio-economically comparable countries with the aim of identifying similarities and differences in how these products are regulated and governed within clinical contexts. We find that while there are many subtle technical differences in how these regulations are implemented, they are sufficiently similar that it is difficult to explain why these practices appear more prevalent in some countries and not in others. We conclude with suggestions for how international governance frameworks might be improved to discourage the exploitation of vulnerable patient populations while enabling innovation in the clinical application of cellular therapies.

The deadly business of an unregulated global stem cell industry.

In 2016, the Office of the State Coroner of New South Wales released its report into the death of an Australian woman, Sheila Drysdale, who had died from complications of an autologous stem cell procedure at a Sydney clinic. In this report, we argue that Mrs Drysdale's death was avoidable, and it was the result of a pernicious global problem of an industry exploiting regulatory systems to sell unproven and unjustified interventions with stem cells.

A question of ethics: selling autologous stem cell therapies flaunts professional standards.

The idea that the body's own stem cells could act as a repair kit for many conditions, including cardiac repair, underpins regenerative medicine. While progress is being made, with hundreds of clinical trials underway to evaluate possible autologous cell-based therapies, some patients and physicians are not prepared to wait and are pursuing treatments without evidence that the proposed treatments are effective, or even safe. This article explores the inherent tension between patients, practitioners and the need to regulate the development and commercialization of new cellular therapies--even when the cells come from the patient.

Ethical and legal issues raised by cord blood banking - the challenges of the new bioeconomy.

• Cord blood banking raises ethical and legal issues which highlight the need for careful regulatory approaches to the emerging bioeconomy. • Consent processes for both private and public banking should be inclusive and representative of the different familial interests in the cord blood. • Property law is a potentially useful way of understanding the mechanisms for donation to both public and private banks. • Increasing tensions between public and private models of banking may require the adoption of hybrid forms of banking.

Analysis of attitudes toward the source of progenitor cells in tissue-engineered products for use in burns compared with other disease states.

The first trials using progenitor cells to improve burn wound healing are beginning. However, there remains a paucity of data on patients' opinions of the source of stem cells. In this study, 279 patients attending plastic surgery/burns outpatient and medical outpatient clinics were questioned to assess willingness to accept a tissue-engineered skin product derived from a variety of sources. Levels of acceptance for the use of progenitor cells derived from these sources for treatment across a range of disease states (burns, Parkinson's disease, diabetes, and for cosmetic use) were also assessed. Overall, 80% of those questioned would accept a tissue-engineered product. Autologous cells were the preferred choice of cells (acute burns 94%, diabetes 95%, Parkinson's 93.9%). Allogeneic cells were still widely accepted (acute burns 67%, diabetes 66.7%, Parkinson's 69.2%). There was no difference observed between plastic surgical patients and medical patients in acceptance of cell therapy for burns, Parkinson's disease, or diabetes. There is good potential acceptance for the use of both autologous and allogeneic cells for the treatment of acute burns and burns' scarring as well as in diabetes and Parkinson's disease. Disease state does not appear to influence overall acceptability and choice of cells.

The clinician-scientist: professional dynamics in clinical stem cell research.

Clinical applications of biomedical research rely on specialist knowledge provided by professionals who straddle research and therapy, and possess both medical and scientific expertise. To date, this professional group remains under-explored in sociology. Our article presents a case study of clinician-scientists working in stem cell research for heart repair in the UK and Germany who are engaged in double-blind randomised clinical trials using patients' own stem cells. The analysis draws on sociological and medical literature, interviews and ethnographic fieldwork to analyse the experiences and self-rationalisations of a small number of clinician-scientists and the ways in which these professionals portray, explain and justify their role in the wider clinical research environment. We examine our participants' views on the clinical trials they conduct, the challenges they encounter and the ways through which they negotiate a complex disciplinary terrain, and argue that the recent clinical implementation of stem cell research brings clinician-scientists to the fore and provides a renewed platform for their professional legitimisation. The article helps increase our understanding of how randomised clinical trials are involved in consolidating the individual status of actors and the collective standing of clinician-scientists as leaders of change in translational medicine.

Ethical issues in autologous stem cell transplantation (ASCT) in advanced breast cancer: a systematic literature review.

BACKGROUND: An effectiveness assessment on ASCT in locally advanced and metastatic breast cancer identified serious ethical issues associated with this intervention. Our objective was to systematically review these aspects by means of a literature analysis. METHODS: We chose the reflexive Socratic approach as the review method using Hofmann's question list, conducted a comprehensive literature search in biomedical, psychological and ethics bibliographic databases and screened the resulting hits in a 2-step selection process. Relevant arguments were assembled from the included articles, and were assessed and assigned to the question list. Hofmann's questions were addressed by synthesizing these arguments. RESULTS: Of the identified 879 documents 102 included arguments related to one or more questions from Hofmann's question list. The most important ethical issues were the implementation of ASCT in clinical practice on the basis of phase-II trials in the 1990s and the publication of falsified data in the first randomized controlled trials (Bezwoda fraud), which caused significant negative effects on recruiting patients for further clinical trials and the doctor-patient relationship. Recent meta-analyses report a marginal effect in prolonging disease-free survival, accompanied by severe harms, including death. ASCT in breast cancer remains a stigmatized technology. Reported health-related-quality-of-life data are often at high risk of bias in favor of the survivors. Furthermore little attention has been paid to those patients who were dying. CONCLUSIONS: The questions were addressed in different degrees of completeness. All arguments were assignable to the questions. The central ethical dimensions of ASCT could be discussed by reviewing the published literature.

The ongoing charity of organ donation. Contemporary English Sunni fatwas on organ donation and blood transfusion.

BACKGROUND: Empirical studies in Muslim communities on organ donation and blood transfusion show that Muslim counsellors play an important role in the decision process. Despite the emerging importance of online English Sunni fatwas, these fatwas on organ donation and blood transfusion have hardly been studied, thus creating a gap in our knowledge of contemporary Islamic views on the subject. METHOD: We analysed 70 English Sunni e-fatwas and subjected them to an in-depth text analysis in order to reveal the key concepts in the Islamic ethical framework regarding organ donation and blood transfusion. RESULTS: All 70 fatwas allow for organ donation and blood transfusion. Autotransplantation is no problem at all if done for medical reasons. Allotransplantation, both from a living and a dead donor, appears to be possible though only in quite restricted ways. Xenotransplantation is less often mentioned but can be allowed in case of necessity. Transplantation in general is seen as an ongoing form of charity. Nearly half of the fatwas allowing blood transfusion do so without mentioning any restriction or problem whatsoever. The other half of the fatwas on transfusion contain the same conditional approval as found in the arguments pro organ transplantation. CONCLUSION: Our findings are very much in line with the international literature on the subject. We found two new elements: debates on the definition of the moment of death are hardly mentioned in the English Sunni fatwas and organ donation and blood transfusion are presented as an ongoing form of charity.
