RESUMO

The unproven stem cell intervention (SCI) industry is a global health problem. Despite efforts of some nations, the industry continues to flourish. In this paper, we call for a global approach and the establishment of a World Health Organization (WHO) Expert Advisory Committee on Regenerative Medicine to tackle this issue and provide guidance. The WHO committee can harmonize national regulations; promote regulatory approaches responsive to unmet patient needs; and formulate an education campaign against misinformation. Fostering an international dialog and developing recommendations that can be adopted by member states would effectively address the global market of unproven SCIs.

RESUMO

Japan's Act on the Safety of Regenerative Medicine (ASRM) created an innovative regulatory framework intended to safely promote the clinical development of stem cell-based interventions (SCBIs) while subjecting commercialized unproven SCBIs to greater scrutiny and accountability. This article reviews ASRM's origins, explains its unprecedented scope, and assesses how it envisions the regulation of SCBIs. This analysis is used to highlight three key insights that are pertinent to the current revision of the ASRM: clarifying how the concept of safety should be defined and assessed in research and clinical care settings; revisiting risk criteria for review of SCBIs; and taking stronger measures to support the transition from unproven interventions to evidence-based therapies. Finally, the article reflects on lessons drawn from Japanese experiences in dealing with unproven SCBIs for international endeavors to regulate SCBIs.

RESUMO

Stem cell-based products (SCPs) are an emerging field of veterinary medicine that focuses on the regeneration, repair, or replacement of damaged tissues or organs. However, there are some issues in applying the traditional regulatory guideline for the approval of SCPs as veterinary medicinal products. This article describes the positions of Korea, US, and EU regarding SCPs, and compares the regulatory guidelines of each country for their safety evaluation. Although there are some differences in the regulatory guidelines, similar considerations in identifying the quality of SCPs and their safety has adopted. Overall, these guidelines need to be harmonized among countries.

RESUMO

In this article I explore how experimental stem cell treatments have become a therapeutic choice in India. Drawing on ethnographic fieldwork, I illustrate six sociotechnical pathways by which clinically unproven treatment is rendered regular health care practice for consumers and providers across the country. Through each pathway, based on the themes of bioconsumption, integration, consumer contacts, treatment experience and rituals, and political culture, I demonstrate how the experimental status of stem cell treatment is undermined and thereby experienced by key stakeholders as just another medical option. In analyzing the pathways, I argue that unproven stem cell treatment practices are promoted and sustained by multiple social, political and technical forces. The discussion on pathways is therefore situated within a conceptual framework of "normalization," derived from studies that investigate the multidimensional aspects to controversial and/or new medical technologies becoming routine.

RESUMO

This article examines how Australian providers of unproven autologous 'stem cell treatments' legitimise these products and their practices. We focus on the strategies employed by providers in their efforts to create and sustain a market for procedures that have yet to be proven safe and clinically efficacious. Drawing on the work of Thomas Gieryn and Pierre Bourdieu and the findings of research involving an analysis of direct-to-consumer online advertising of clinics that sell purported 'stem cell treatments' and interviews with clinicians who provide them, we examine the mechanisms by which medical legitimacy for these products is established and defended. We argue that Australian providers employ a number of strategies in order to create medical legitimacy for the use and sale of scientifically unproven therapies. A key strategy employed by providers of stem cell treatments is to use markers of social distinction, drawing strongly on the symbols of science, to confirm their legitimacy and differentiate their own practices from those of other providers, who are posited as operating outside the boundary of accepted practice and hence illegitimate. We argue there is a paradox at the heart of the autologous stem cell treatment market. Providers aim to create legitimacy for their work by emphasising the potential benefits of their 'treatments', their expertise and the professionalisation of their practices in an environment where regulators are yet to take a firm stance; they are also required to undertake the challenging task of managing patients' hopes and expectations that both enable and potentially jeopardise their operations and revenue. We conclude by suggesting that providers' creation of symbolic capital to establish medical legitimacy is a crucial means by which they seek to bring unproven 'stem cell treatments' from the margins of medicine into the mainstream and to portray themselves as medical pioneers rather than medical cowboys who exploit vulnerable patients.

RESUMO

'Requirements for Human Embryonic Stem Cells' is the first set of guidelines on human embryonic stem cells in China, jointly drafted and agreed upon by experts from the Chinese Society for Stem Cell Research. This standard specifies the technical requirements, test methods, test regulations, instructions for use, labelling requirements, packaging requirements, storage requirements and transportation requirements for human embryonic stem cells, which is applicable to the quality control for human embryonic stem cells. It was originally released by the China Society for Cell Biology on 26 February 2019 and was further revised on 30 April 2020. We hope that publication of these guidelines will promote institutional establishment, acceptance and execution of proper protocols, and accelerate the international standardization of human embryonic stem cells for applications.

RESUMO

In 2018, Australia's Therapeutic Goods Administration introduced regulatory reforms that set stricter criteria around the regulation of products derived from a patient's own cells and tissues, posing significant implications for clinics offering stem cell treatments. We review the regulatory framework and discuss its potential commercial implications, including the ambiguities that may arise from it in practice, as well as the likely impact it will have on product development and advertising practices in the future.

RESUMO

Cell therapies hold significant promise for the treatment of injured or diseased musculoskeletal tissues. However, despite advances in research, there is growing concern about the increasing number of clinical centres around the world that are making unwarranted claims or are performing risky biological procedures. Such providers have been known to recommend, prescribe, or deliver so called 'stem cell' preparations without sufficient data to support their true content and efficacy. In this annotation, we outline the current environment of stem cell-based treatments and the strategies of marketing directly to consumers. We also outline the difficulties in the regulation of these clinics and make recommendations for best practice and the identification and reporting of illegitimate providers.

RESUMO

The prevalence of businesses selling autologous stem cell-based interventions to patients in Australia has raised serious concerns about how weaknesses in regulation have enabled the emergence of an industry that engages in aggressive marketing of unproven treatments to patients. Little is known about how patients experience this marketing and their subsequent interactions with practitioners. This paper reports results from 15 semistructured interviews with patients and carers, and also draws upon discussion conducted with patients, carers and family members (22 participants) in a workshop setting. We explore how Australian patients and carers understand and experience these interventions, and how their presumptions about the ethics of medical practice, and the regulatory environment in Australia have conditioned their preparedness to undergo unproven treatments.

RESUMO

Aim: The industry of unproven stem cell clinics has rapidly mushroomed throughout the USA, posing risks to patients and the research field. In this study, the aim was to better define how this industry changes. Methods: I analyzed a large cohort of US stem cell clinic firms and their distinct clinic locations as defined in 2015-2016 for their status now in 2019. Results: About a quarter of the firms no longer marketed stem cells. Some lacked active websites, while others dropped stem cell services. Even so, the total number of clinics in this group increased because some firms greatly expanded their clinic numbers. Conclusion: Overall, the unproven clinic industry is a moving target requiring ongoing study and regulatory oversight.

RESUMO

BACKGROUND: The marketing of unproven direct-to-consumer stem cell interventions is becoming widespread in Canada. There is little evidence supporting their use and they have been associated with a range of harms. Canada has been slower to act against clinics offering these interventions than other jurisdictions, including the United States. Here, we outline the regulatory and policy tools available in Canada to address this growing problem. MAIN BODY: Health Canada's regulations governing cell therapies are complex, but recent statements make it clear that Health Canada believes it has jurisdiction over many of the currently marketed stem cell interventions. Still, further regulatory clarity is needed from Health Canada, as are increased directed enforcement efforts on interventions that fall within their scope. The Competition Bureau, via the Competition Act, prohibits advertisers from making materially false or misleading promotional representations. The Competition Bureau could collaborate with the scientific community to analyze the claims of existing clinics in Canada, and impose sanctions upon those who breach the established standard. Professional regulators, including provincial colleges of physicians and surgeons, have considerable power over what products and services their members can offer. Every college of physicians in Canada requires, via policy and codes of ethics, that doctors maintain evidence-based practices. This requirement is incompatible with offering many unproven stem cell interventions. Litigation may be another tool, including the use of fraud, misrepresentation and/or negligence claims for failing to meet the required standard of care. Finally, political pressure on federal and provincial lawmakers could encourage changes to marketing, cell therapy and professional regulations that would allow a more comprehensive response. CONCLUSIONS: In sum, there are many existing tools that can be used to protect the public from unproven stem cell interventions. Increased bureaucratic will and grassroots efforts are needed in order to effect a positive policy response.

RESUMO

The process of developing new and complex stem-cell-based therapeutics is incremental and requires decades of sustained collaboration among different stakeholders. In this Perspective, we address key ethical and policy challenges confronting the clinical translation of stem-cell-based interventions (SCBIs), including premature diffusion of SCBIs to clinical practice, assessment of risk in trials, obtaining valid informed consent for research participants, balanced and complete scientific reporting and public communications, regulation, and equitable access to treatment. We propose a way forward for translating these therapies with the above challenges in mind.

RESUMO

BACKGROUND: Nowadays one of the most critical aspects of innovative cell-based therapies is the unregulated industry, as it is becoming a competitor of the regulated system. Many private clinics, worldwide, advertise and offer cell-based interventions treatments directly to the consumer and this poses a risk to both vulnerable patients and health systems. Several countries have implemented Compassionate Use Programmes (CUP) that provide patients with medicines that have not yet completed the approval pathway, in the event that no reasonable alternative exists. Recently, in the public discourse, compassionate use has been increasingly associated with a patient's right to try. Thus, the aim of this study was to assess public knowledge of the clinical trials process with specific reference to innovative stem cell treatments, and trust in the institutions responsible for regulatory activities. We also asked people about their "right" to use unregulated therapies. METHODS: We developed an ad hoc questionnaire on three main areas of concern and administered it to 300 people in the patient waiting room at an Italian university hospital. RESULTS: Our findings suggest that people have a good knowledge of the clinical trials process and trust in healthcare institutions. Nonetheless, one person in two believes it is a right to use unregulated therapies. CONCLUSIONS: We stress the need, in the age of cellular therapies, for a commitment to support vulnerable patients and to strengthen awareness among the public about the substantial boundary that differentiates experimental therapies from unproven therapies. There should not be a "right to try" something that is unsafe but rather approved treatments and in line with good clinical practice. The trend, which emerged on this issue from our study, is quite different, confirming the urgent need to improve health information so that it is as complete as possible.

RESUMO

We provide an overview of the regulatory framework, pathways and underlying regulatory authority for cell, gene and tissue-engineered therapies in Canada. Canada's regulatory approach uses three sets of regulations, namely, the Cells, Tissues and Organs Regulations, the Food and Drug Regulations and the Medical Devices Regulations. We provide an overview of each these sets of regulations as they apply to clinical investigation to post-market product lifecycle stages. Information is provided on the current sources of relevant Health Canada guidance documents. We highlight several regional success stories including Prochymal, a cell therapy product that achieved Canadian regulatory approval using the conditional marketing approval system. We also examine the perceived gaps in the Canadian regulations and how those gaps are being addressed by interactions between the government, stakeholders and international bodies. We conclude that the risk-benefit approach used by Health Canada for regulatory approval processes is sufficiently flexible to enable to development of novel cell and gene therapy products in Canada, yet stringent enough to protect patient safety.
